The best strimmer for your garden will ideally be cordless, as it’s safer and frees up your mobility. Of course, you’ll then want good battery life (I recommend at least 30 minutes), and a fast charging time. It also needs a cutting width of at least 25cm, and enough power and speed to cut through long grass, weeds and even brambles. Weight is a big factor to avoid aching arms, so the lighter the better. Lastly, a telescopic shaft will enable you to adjust the height perfectly to your needs. 

I’ve significantly researched and field tested the best cordless strimmers and it’s incredible how differently they perform. Below I present to you my findings and recommendations for a variety of strimming scenarios…

BLACK+DECKER STC1802PC-GB Cordless Strimmer Review

Specifications

  • Weight: 2.6kg
  • Cutting Width: 28cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 120m
  • Max. Running Time: 40m
  • Battery: 2.0 Ah lithium-ion
  • Power: 18V
  • Max. Speed (RPM): 7400 RPM
  • Noise Level (Decibels): Not listed
  • Telescopic Shaft?: Yes

For cutting the grass without a mower, and neatly edging the lawn, the BLACK+DECKER STC1802PC-GB Strimmer offers both a trimmer and a wheel edger in one convenient unit. It’s easy to switch between the two settings, meaning time isn’t wasted moving between tasks, and it does both jobs efficiently.

Plus, it’s able to hack through overgrown grass, weed patches, nettles and plant stems – your unruly garden undergrowth doesn’t stand a chance!

With a rechargeable 18 V lithium-ion battery, you get between 15- and 40-minutes run time to play with, depending on which setting you use.

It can chop through some thicker vegetation with persuasion and a methodical approach, but you’ll need to use the Turbo Mode setting and the battery won’t last as long. This strimmer is best suited to use on smaller areas of long grass, in places that the lawn mower can’t reach, as this is where you’ll be able to get the most out of the battery and the unit using the ECO mode.

Being cordless certainly has its advantages, and this electric strimmer can be used anywhere you like without the necessity for a mains connection; we’re talking allotments, awkward corners of the garden, and tucked-away flowerbeds. With a high-torque gear system that can whizz through overgrown areas at 7400 rpm, this strimmer puts its 28cm-wide cutting swathe to good use. It’s wide enough to pack a punch yet can still fit into smaller spaces.

The telescopic handle and adjustable hand-grip make this strimmer suitable for a range of different users, and it weighs a reasonable 2.6 kg which isn’t bad for a cordless strimmer. I’d say this sits roughly in the middle of the strimmers on this list.

There is an option to change between functions, from strimmer to lawn edger, and this can be easily done by simply shifting the head through 90 degrees. With a built-in wheel guide, which not every strimmer/edger has, unit can produce a neat finish, omitting the need for two separate tools to do this job.

Pros

  • The boost setting works well to cut small weeds.
  • Assembly is straight forward and does not take long.
  • The edging wheel gives the option of creating a neat edge to the lawn.
  • Reasonable charging time of 120 mins even without 'fast' charger.

Cons

  • Battery life may be as little as 15 minutes depending on the task in hand.
  • Not suitable for larger overgrown areas because of battery life, but will work well for smaller spaces.
  • It should predominantly be used to cut long grass, as thicker vegetation will drain the battery.

Swift Cordless Grass Strimmer Review

Specifications

  • Weight: 2.4kg
  • Cutting Width: 25cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 90m
  • Max. Running Time: 73m
  • Battery: Lithium-ion
  • Power: 40V
  • Max. Speed (RPM): 9000 RPM
  • Noise Level (Decibels): 80dB
  • Telescopic Shaft?: Yes

If you’ve had enough of strimmers with nylon cutting line, there are other options out there. The Swift Cordless Grass Strimmer uses plastic nylon blades which spin around at an impressive speed to cut down grass without a string in sight.

It has good speed and power for an electric model and the blades are surprisingly forceful. They’ll cut through thicker grass and undergrowth more efficiently than an equivalent single-cutting-line model.

Running at 900 RPM, with a 40 V battery that can last up to an impressive 73 minutes, this is one of the best garden strimmers for larger gardens – you can still avoid being tethered by a mains cord, but also achieve a decent cutting time. Of course, as with all strimmers, the battery run time is somewhat dependent on how hard the strimmer is having to work.

It trims and edges, and is easy to switch between the two functions. After strimming, simply twist the pole to turn it into an edger and give your lawn borders a neat and tidy finish.

Weighing just 2.4 kg, this Swift grass trimmer is one of the lightest strimmers featured on this list. Lighter tools can often be more comfortable for those with arthritis or people who struggle with upper-body strength, so it’s worth bearing this model in mind if this is relevant to you.

Finally, there is a two-button start system – this is a reassuring safety feature which means the strimmer can’t be accidentally turned on. The buttons must be used together, creating a safer tool.

One thing to bear in mind is that the blades can snap off or break if they hit something hard. They’re replaceable, and not overly fragile, but you’ll probably want to buy replacements alongside the initial purchase just to be prepared.

Pros

  • Time isn't wasted re-threading or feeding any cutting line because this machine has blades instead.
  • Can run for upwards of an hour when used for general domestic use.
  • There is a holder for storing spare blades on the unit, making them easily accessible.
  • The shaft can split into two making it easy to store and transport.
  • The blades are easy to take off and put on if they need replacing.

Cons

  • Plastic cutting blades may not be suitable for gardens with lots of stones - can hit them and break (note: blades are replaceable).
  • The length may be a little short for people over 6ft
  • It's better as a strimmer than edger as there is no wheel guide for edging.
  • It doesn't have a flower guard so you have to be mindful not to get too close to plants.

WORX WG163E.2 Cordless Grass Trimmer Review

Specifications

  • Weight: 2.4kg
  • Cutting Width: 30cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 180m
  • Max. Running Time: 30m
  • Battery: 2.0 Ah lithium-ion
  • Power: 20V
  • Max. Speed (RPM): 7600 RPM
  • Noise Level (Decibels): 80dB
  • Telescopic Shaft?: Yes

For more extensive jobs, the WORX WG163E.2 Cordless Grass Trimmer comes with two batteries and a charger so you won’t get unceremoniously cut off before the job’s done.

With a push-button spool system for automatic line feeding, you don’t even need to stop to change the line; work can continue, uninterrupted, for as long as the battery lasts. Which, seeing as two batteries come included, is quite a long time!

Both batteries are capable of providing approximately 30 minutes of power, and they’re used one at a time, meaning one can be switched out for the other when the first goes flat. They charge in around one hour using the fast-charger provided, resulting in quite a lot of cutting-time potential from this WORX strimmer.

At just 2.4 kg this tool is easy to manage, and its cordless nature means it can be taken anywhere in the garden. It’s best suited to use on long grass, as opposed to patches of thick weeds and shrubbery, but will capably take the place of a mower especially in areas that larger machines just can’t reach.

Featuring a flower-protector bar, your chrysanthemums can let out a sigh of relief as you whizz past them, neatly strimming the grass without accidentally catching any prized plants in your storm.

Pros

  • Comes with two batteries, and fast charger - expensive to buy separately and therefore good value.
  • The edger works well to create very clean lines around the borders.
  • Each battery, when fully charged, lasts for around 30 minutes - 1 hour total strimming time!
  • Helps cut long grass in 'bumpy' or difficult areas that mower can't trim on.

Cons

  • Not really strong enough for use on thicker vegetation - best suited to cutting grass.
  • There are no written instructions (just pictures) and they don't make it clear how to use some of the features.
  • The cutting head can be difficult to adjust requiring quite a lot of force.
  • The spools only hold a small amount of wire which means they need to be replaced more often.
  • The batteries do not have an indicator light to display how much charge remains.

Bosch AdvancedGrassCut Cordless Grass Trimmer Review

Specifications

  • Weight: 2.9kg
  • Cutting Width: 30cm
  • Battery Included?: No
  • Charge Time (Minutes): Depends on battery
  • Max. Running Time: Depends on battery
  • Battery: Ah Lithium-ion
  • Power: 36V
  • Max. Speed (RPM): Not Listed
  • Noise Level (Decibels): 74dB
  • Telescopic Shaft?: Yes

If you’ve got a medium garden, you’re probably after something with reasonable battery life that will provide a reliable cut – it’s especially important in slightly larger spaces that you don’t have to waste time going over the same patch twice.

As you might expect from Bosch, their AdvancedGrassCut Cordless Grass Trimmer has been very well designed indeed. It has a powerful 36 V battery (although you’ll have to buy this separately) and it can tackle long grass and nettles. You’ll be able to use it for edging as well, so it’s an all-round useful tool to have in the shed.

The battery is also compatible with some other Bosch tools. For example, it’s the same battery that is used by Bosch’s Rotak cordless lawnmower, so if you already own some of these products, you’ll likely be able to share the batteries between machines. Having one battery on charge whilst using the other is a useful way to extend cutting time.

With a dual-line cutting system, this strimmer has a bit more power behind it than many other models featured on this list which are only single line. Strimmers with two cutting lines tend to be able to take on tougher vegetation, and this Bosch model certainly won’t get stuck when cutting through thicker grass.

An auto-feed line system provides about 1 cm of new line each time you switch on the strimmer meaning there’s no bump-feed to contend with. The only thing to bear in mind is to avoid switching the strimmer off and on more than necessary, as new line will be fed through each time whether you need it or not.

In terms of comfort, at 2.9 kg this isn’t the lightest model featured; however, it does have an ergonomic handle and second-hand support which help make it more comfortable. The length of the shaft and position of the support can also be altered, and there is an option to attach a shoulder strap as well. A strap doesn’t come included, but can be purchased separately to help balance the weight further.

Unlike some other models, which last for around 30 minutes only on their ‘eco modes’, this Bosch cordless grass trimmer has a slightly better run time as it can work for 30 minutes whilst cutting thicker vegetation too.

In terms of pricing, it’s definitely one of the more expensive models on the list, but if you’re after a strimmer with a bit more power behind it to tackle thicker vegetation, this one is probably worth paying a bit extra for.

Pros

  • Can tackle long, thick grass without problems.
  • Battery lasts for approximately 30 minutes.
  • Has loops to attach a shoulder strap (not included) which can make it more comfortable.
  • It's easy to change the angle of the cutting head, making it simple to change to lawn edging.

Cons

  • As the battery starts to die, the strimmer may struggle to auto feed the line out.
  • No variable speed option so you need to be careful not to damage tree trunks etc.
  • The line auto-feeds when machine is turned back on whether you want it to or not - can be wasteful.
  • It can feel quite heavy after a while, although a strap can be purchased separately.

BLACK+DECKER GLC3630L20 Cordless Strimmer Review

Specifications

  • Weight: 3.5kg
  • Cutting Width: 30cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 120m
  • Max. Running Time: 30m
  • Battery: 2.0 Ah lithium-ion
  • Power: 36V
  • Max. Speed (RPM): 8500 RPM
  • Noise Level (Decibels): 80dB
  • Telescopic Shaft?: Yes

Whether you’re looking for a tool to help cut the lawn in areas your mower can’t reach, or want to hit back at some thicker weeded patches, the BLACK+DECKER GLC3630L20 Cordless Strimmer has the power to help with both.

Able to run at 8500 RPM, this strimmer’s turbo mode is pretty powerful stuff, even capable of tearing through thicker plants like thistles. On eco mode the battery will last around 30 minutes and, whilst not as intense as turbo, it still packs enough of a punch to chop through grass of 10 – 20 cm in length.

A tool like this, with its 30 cm cutting swathe, is ideal for awkwardly-shaped borders or edging narrow pathways. The 30 minute battery life offers a reasonable amount of time to get jobs done, plus, the added convenience of battery power means there’s no cord to worry about accidentally cutting through.

Thanks to its decent cutting with and the auto-spool cutting line, this Black +Decker strimmer moves efficiently through the undergrowth.

With a battery that charges in around 120 minutes, you’ll be able to get a lot out of this strimmer even if you have a slightly larger garden – you might just have to break up the task throughout the day.

Additional batteries are available to purchase as well, which can be useful as one battery can charge whilst the other is in use. However, the batteries are quite expensive, so this isn’t a solution for everyone.

Where I feel this model lets itself down is the weight. At 3.5kg it’s definitely on the side heavier side for cordless strimmers. Every 10-15 minutes I find myself putting it down to give me arms a little break. If you’ve got a larger garden, this perhaps isn’t the right strimmer for you, however if it’s small to medium, it probably won’t be an issue.

Pros

  • Runs for approximately 30 mins in ECO mode, which is a lot of time to get strimming done.
  • Recharges quickly in around two hours which is fairly good for battery-powered machines.
  • Adjustable length means it is comfortable for users of most heights.
  • The turbo mode can tackle thick vegetation like weeds and thistles.
  • Gradient battery-power lights keep you well informed about how much battery power is left.

Cons

  • A little too much on the heavy side for my liking at 3.5kg
  • Battery life on full/turbo power (required for tackling thicker grass/plants) is around 10 mins.
  • Additional batteries can be purchased but are expensive.
  • After a couple of years the battery may need replacing; some users report they stop charging well.
  • The edging function is not this strimmer's best attribute.

Ryobi OLT1832 ONE+ Cordless Grass Strimmer Review

Specifications

  • Weight: 2.3kg
  • Cutting Width: 25cm or 30cm
  • Battery Included?: No
  • Charge Time (Minutes): Depends on battery
  • Max. Running Time: Depends on battery
  • Battery: Ah Lithium-ion
  • Power: 18V
  • Max. Speed (RPM): Not Listed
  • Noise Level (Decibels): 94.2dB
  • Telescopic Shaft?: Yes

If you’re a fan of the Ryobi range, the Ryobi OLT1832 ONE+ Cordless Grass Strimmer is an excellent investment that is both powerful and versatile. In fact, even if you’re not yet familiar with Ryobi, you may well become a convert after using this strimmer.

Straight off the bat it’s worth pointing out that this unit does not come with a battery or charger included – hence the bargain price.

The thing with Ryobi ONE+ products is that the batteries can be used across the whole tool range. As a result, you only really need to invest in one battery and charger, and then you’ll be able to benefit from buying these well-priced ‘bare’ machines in the future.

With an adjustable cutting width of 25-30 cm, and a pivoting head, this Ryobi strimmer can get into smaller spaces than most other models – a fixed 30 cm width is generally considered standard. It’s therefore perfect to use in tight corners and around smaller features.

The telescopic handle and reasonably light weight also make it easy to manage in any awkward areas of the garden. This unit weighs 2.3 kg without the battery attached, so the weight of the battery will dictate how heavy it is in use.

The cutting line adjusts automatically, by simply easing off the power when necessary, and it’s easy to adjust between trimming and edging. There’s no edging wheel included, which can make it harder to create a straight line, perhaps resulting in a machine that is more suitable for cutting grass than tidying up edges in general.

Whilst the battery isn’t included, this strimmer can get good mileage out of different batteries: a 2.5 Ah battery will last for around 25-30 mins, whilst a 5.0 Ah battery can last for up to an hour.

Pros

  • Will tackle areas with light weeds.
  • With a 5.0 Ah battery it will run for approximately 1 hour.
  • Height adjustable handle means suitable for a range of users and easier to store.
  • Small head size makes it easier to get into corners where the mower won't reach.
  • Easy to assemble and start using in under 10 minutes.

Cons

  • The battery and charger do not come included.
  • Unlikely to work effectively in areas that are overgrown or have a lot of weeds.
  • No wheel-guide for trimming edges so can be harder to do neat finishes.
  • Changing the cutting width is not easy enough to do frequently, requires unscrewing and re-affixing the unit.
  • Nosiest strimmer on this list at 94.2 decibels. Not the best for keeping peace with the neighbours!

Flymo Contour Cordless Grass Trimmer Review

Specifications

  • Weight: 3kg
  • Cutting Width: 25cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 180m
  • Max. Running Time: 33m
  • Battery: 2.5 Ah lithium-ion
  • Power: 20V
  • Max. Speed (RPM): Not Listed
  • Noise Level (Decibels): 74.4dB
  • Telescopic Shaft?: Yes

Whether you have narrow areas in your garden that are difficult to cut, or are looking for a strimmer that generally won’t be too difficult to manoeuvre, the Flymo Contour Cordless Grass Trimmer has a relatively thin 25 cm cutting width with a weight and design that isn’t unwieldly.

It’s multifunctional, working as a trimmer and edger, with a plant guard that will keep your blooms safe as you tidy up the borders. There is also a foot pedal which helps adjust the cutting angle. As a result, it’s easy to alter even in cramped areas where it might be awkward to bend down.

Weighing in at 3 kg, this Flymo strimmer isn’t too heavy for use in small to medium gardens, plus it’s not overly cumbersome so it can be used in tight spots without too much difficulty. Of course, after a while this weight can start to put strain on the arms, and lighter models are available, but this Flymo Countour provides a good compromise between weight, battery life, and power.

The battery will last for around 20 – 30 minutes depending on the job in hand, and only takes approximately 180 minutes to fully recharge. Best suited to normal domestic use – some long grass and general garden edging, you’ll likely find you can get a lot done from just one charge.

Pros

  • Guide wheel works well and creates a good, neat edge when used as a lawn edger.
  • The LED lights on the battery are helpful to see how much battery is left.
  • Only 74.4 decibels makes it the second quietest model on this list

Cons

  • The plant guard can get in the way when strimming up close to fences, but it can be removed.
  • Just one speed - no ECO mode - so there is no option to extend batter power run time.
  • The diagram assembly instructions are very small and hard to read - the written ones are slightly better.

Terratek Cordless Strimmer Review

Specifications

  • Weight: 2kg
  • Cutting Width: 25cm
  • Battery Included?: Yes (Two)
  • Charge Time (Minutes): 180-300m
  • Max. Running Time: 40m
  • Battery: 1.3 Ah lithium-ion
  • Power: 20V
  • Max. Speed (RPM): 8000 RPM
  • Noise Level (Decibels): 82.8dB
  • Telescopic Shaft?: Yes

Offering excellent value, the Terratek Cordless Strimmer comes with two batteries and a charger included, as well as 30 replacement blades. One battery lasts for around 30 – 40 minutes (whilst doing relatively light work) meaning you can often achieve a run time of over an hour.

Given that this Terratek strimmer is both cordless and lightweight, it’s very easy to carry around. At 2 kg, it can be used for the duration of its battery-run-time without causing too much fatigue.

If you have a larger garden, with patches of normal lawn that can get a bit overgrown, this is a helpful tool to have around. It provides the freedom of not being connected to mains power, with a battery that will last long enough to navigate a bigger area. That said, this machine shouldn’t be expected to cut through thicker vegetation – the motor can struggle in denser areas, although a methodical top-down approach will see it get through nettles.

Like many strimmers, the Terratek Cordless Strimmer has a head that can be rotated through 90 degrees to help with lawn edging. It doesn’t have an edging guide wheel though, so is best purchased primarily with strimming in mind.

There’s no nylon cutting string to thread or untangle as it uses a blade cutting system instead. For those who are fed up of fighting with string strimmers, this can offer a welcome alternative.

Cutting at a width of 25 cm, the blades trim well on normal grass, but you do need to be careful not to catch them on hard surfaces as they can break. Replacement blades are easy to attach and can be purchased in bulk online – 30 spares come included with the strimmer as mentioned.

Pros

  • Long battery life of around 30 - 40 minutes.
  • Two batteries included meaning overall running time is 1 hour +
  • The lightness of it means you can use it for the battery run time without getting too tired.

Cons

  • Getting too close to solid objects like walls/paving can damage blades.
  • With no wheel guide the strimmer is not very easy to use for edging.
  • Some customers have found that the plastic safety guard is easily knocked off, requiring relatively frequent reattaching.

Garden Gear Cordless Strimmer Review

Specifications

  • Weight: 1.86kg
  • Cutting Width: 26cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 180-300m
  • Max. Running Time: 30m
  • Battery: Ah Lithium-ion
  • Power: 20V
  • Max. Speed (RPM): Not Listed
  • Noise Level (Decibels): 89.9dB
  • Telescopic Shaft?: Yes

For a mid-range strimmer that offers a good balance of quality and value, the Garden Gear Cordless Strimmer is a worthy option to consider. As a bladed model, there’s no nylon cutting string to contend with, and the 20 V lithium-ion battery offers reasonable power without being excessive.

If you’re looking for something that will simply tidy the lawn where the mower can’t reach, this 20 V machine has enough power to get through grass and nettles. Plus, it’s cheaper than more powerful models.

That said, if your garden is looking a bit more ‘Jungle Book’ than ‘Stepford Wives’, this Garden Gear option might not be the best strimmer for you – it’s not cut out for tackling thicker undergrowth.

The battery tends to last in the area of 20-30 mins, depending on how much you put it through its paces, and there’s no spare battery included. Batteries can be bought separately but, if we just consider this unit as it’s sold, it’s going to be best suited to small to medium gardens.

With a 26 cm cutting width, this strimmer is well designed to fit into the places where the mower can’t go. It also comes with an edge guide and detachable wheel to make it easy to create neat lawn edges.

The lightweight aluminium shaft is what helps keep the weight down; at just 1.86kg, this strimmer is the lightest model on the list and best suited for older people or those concerned about the tool weight.

Adjustable from 95 to 115 cm, Garden Gear have created a strimmer which is comfortable for a range of users. Plus, the strimmer head is adjustable as well, up to an angle of 90 degrees, which makes it easy to use in awkward areas and on slopes.

However, at 89.9dB it’s also the loudest strimmer too! So if you’re concerned about upsetting the neighbours, this may not be the right option for you.

Pros

  • Suitable for a small/medium garden: battery lasts 20 - 30 mins.
  • Head angle and handle length can be adjusted so it's comfortable for most users.
  • Lightweight enough to lift and strim at an angle to cut on a banked lawn.
  • Will cut through grass and nettles quickly.

Cons

  • Blade will struggle to cut through tougher patches like brambles.
  • If cutting longer grass you may have to stop to unwrap it from around the blades.
  • Due to battery life and blade strength it isn't very suitable for overgrown gardens.
  • Noise of strimmer increases through use as blades wear down.

Makita DUR181Z Cordless Garden Strimmer Review

Specifications

  • Weight: 3.1kg
  • Cutting Width: 26cm
  • Battery Included?: No
  • Charge Time (Minutes): Depends on battery
  • Max. Running Time: Depends on battery
  • Battery: Ah Lithium-ion
  • Power: 18V
  • Max. Speed (RPM): 7800 RPM
  • Noise Level (Decibels): 88.5dB
  • Telescopic Shaft?: Yes

If you’re after a tool that will neaten up borders and edges, the Makita DUR181Z Cordless Garden Strimmer is well designed to get right up close to boundaries whilst creating a neat, reliable finish.

With a single nylon cutting line, it’s more delicate than strimmers with a double line, making it suitable for lighter gardening tasks without being unwieldy. It might not be the best tool for cutting through thicker undergrowth like brambles, but for tidying garden edges and patches of overgrown grass around trees, it’s all you’ll need.

If you’ve got other Makita tools in your shed, this strimmer will be able to run off the same battery. Similarly to the Ryobi ONE+ strimmer, the battery and charger don’t come included with this Makita model; however, buying ‘bare’ machines like this can keep costs down. You often get a better-quality machine, without spending as much as you would if a battery were included, and can transfer the battery between tools.

To help with comfort, this strimmer can be adjusted to suit your height, and the cutting angle can be changed. As a result, if you are strimming the grass and suddenly spot a border that could do with a bit of edging, it’s quick to change between the two.

The line is fed by simply pushing the bump feed against the ground, making this less of a hassle than non-bump-feed strimmers. Plus, as with all cordless tools, there’s no need for trailing cords or extension leads.

And, finally, whilst aesthetics aren’t everything when looking at garden tools, the design of this Makita strimmer is somewhat uninspiring and looks a bit dated. If you’re after something a bit more modern looking, you’re perhaps better suited to Black+Decker or Worx.

Pros

  • If you already own Makita products with a battery, this offers extremely good value.
  • The handle and head can be tilted making it easier to use on slopes.
  • Useful for smaller patches and clumps of grass that can't be reached with the mower.

Cons

  • The single nylon cutting line is best suited to cutting grass only.
  • Unlikely to be powerful enough for thick patches of nettles and tough vegetation.
  • The shaft length may be a bit short if you are over 6ft.
  • Unit is on the heavier side compared to other models at 3.1kg.

Things to Know Before Buying a Cordless Strimmer

Using a cordless strimmer is an excellent way to achieve a tidy lawn, with none of the back-breaking effort of using lawn shears or scissors.

Compared to other designs, cordless strimmers are one of the best options to go for – you’re not held back by a mains cable, or the weight of a petrol machine.

Often, mains-powered tools need to be used with an extension cable in the garden, and this can sometimes be too much to bother with. It’s always a better idea to have a tool that you won’t put off using, and cordless strimmers save a lot of hassle. Ultimately, if the strimmer is easy to use and it’s comfortable – you’re more likely to use it.

Are you in the market for a new garden strimmer? It’s worth considering a few factors before making a purchase. Check out the tips below to help you make an informed decision:

How Garden Strimmers Work

Garden strimmers tend to cut using either a cutting line, or cutting blades.

Cutting Line Strimmers

Models that use a cutting line generally have one or two lines of nylon line inside the head of the strimmer. The strimmers work using centrifugal force. The line is no good for cutting when at rest, but it becomes stiff and blade-like when it spins quickly.

Single-line strimmers have less cutting force than double-line strimmers, but sometimes that isn’t a bad thing. The best design for you will depend on what jobs you’re doing; some people find strimmers with a double cutting line to be too strong, as they can damage tree trunks, flower pots or fencing if you get too close.

As the line wears down, new line needs to be fed into the cutting head from the spool. Sometimes this is done manually, but most strimmers have a system in place to make this process automatic or semi-automatic.

There are two main systems for distributing more line: ‘bump feed’ and ‘automatic feed’.

Cutting-line strimmers with a ‘bump feed’ system require you to ‘bump’ the strimmer on the ground to release more line. This means that you’re in control of when to release more line, and can help control how quickly line is used.

‘Automatic feed’ strimmers release more line each time the machine is turned back on. In principle this makes sense; however, it can sometimes result in going through line much faster. Imagine – if you’re using a cordless strimmer, you’ll likely keep turning off the unit as you move around the garden to save battery, and then when you turn it on, new line will automatically be released.

Some people prefer the automatic system to the ‘bump feed’ system, you just need to be aware that it could use more line.

Bladed Strimmers

A design which is slowly growing in popularity, bladed strimmers generally have two nylon blades on the head of the strimmer which spin at significant speed. As they spin, they generate a lot of cutting power.

The blades are replaceable, and generally you’ll need to replace a blade every couple of hours use. This is because they can get damaged, and occasionally they’ll come off and get lost in the garden. Generally, about 10 – 20 spare blades will come included with the strimmer, with replacement packs of around 30 blades available for about £10 online.

In terms of cutting power, blades and cutting line are pretty evenly matched. Some gardeners have grown tired of messing with cutting line and prefer the bladed models, but others don’t enjoy having to replace the blades.

The Benefits of Using a Cordless Strimmer

Cordless strimmers make it easier to move around the garden to access patches of grass that the lawnmower can’t reach. As with all strimmers, they create light work of cutting grass, with some models even being capable of tackling brambles and heavier undergrowth.

The added benefit of a cordless strimmer, of course, is that you are not restricted by the length of the power cable. And having the use extension cables? Forget it! Tripping hazards are a thing of the past with cordless strimmers. Plus, you can even use them out on the allotment without having to mess around with generators and the like.

Many cordless strimmers also have wheel-guide edging attachments, which means they can be used to neatly edge borders anywhere in the garden. If you’re mowing the garden and spot some untidy edges, you can be safe in the knowledge that you can get them later when you go round with the strimmer. No matter where it is, with no cables in sight, and using only one multi-functional tool.

How to Use a Cordless Strimmer

Cordless strimmers naturally require you to be slightly more organised compared to mains-powered tools – charging the battery needs to be done in advance to avoid disappointment when it’s time to tackle the garden.

If you don’t wear the battery all the way down, you’re unlikely to need to recharge it before using it again; the lithium-ion batteries used in cordless tools hold their charge relatively well. Of course, charging before use will make sure that you get the most run-time possible from your cordless machine.

Generally speaking, using a cordless strimmer is quite intuitive. There is usually a simple start button which will start the motor going. It may take a bit of practise, and trial and error, to work out where the cutting line is, but this doesn’t take long.

One side of the strimmer will host the cutting edge, and debris will shoot out from the other side. Experiment until you know which is which, otherwise you’ll walk against the cutting direction.

Go slowly with the strimmer regardless of whether it’s an edging job or a tougher task – rushing can cause an uneven cut (and can also be dangerous) so it’s better to take your time to avoid having to go back over the same spot twice.

Finally, look out for tripping hazards. Bricks, small fences, garden ornaments, cats, dogs and small children can all trip you up when you’re concentrating on creating a perfect line! Best to clear the parameters first just to be sure.

Why Choose Cordless Over Mains Powered?

As discussed, both cordless and mains-powered strimmers are available. Petrol models are available too, although they’re generally not necessary for domestic use, so here we’re going to mainly focus on electric models.

Firstly, a look at the main features of each style:

Mains-Powered strimmers plug into the mains. They are powerful and there’s no battery to run down – their run-time is essentially limitless.

However, corded strimmers can cause problems sometimes. Some people worry about cutting the cord with the strimmer, which is an understandable concern. Also, as mentioned several times above, mains-powered strimmers limit you in terms of where you can go in the garden. Generally, they have a mains cable of up to 10 m long, so for anything bigger than a small garden, or for reaching awkward places, an extension cable will be needed.

Cordless strimmers are battery powered so have a limited amount of run-time before you need to stop and charge them. However, the batteries generally last around 30 – 45 minutes, depending on the job, which is a reasonable amount of time for getting a lot done.

Cordless strimmers can be much easier to manoeuvre than their corded counterparts. Not only is there no potentially-hazardous cord to accidentally cut or trip over, but there’s no cord restricting your movement either.

Petrol strimmers are heavier but more powerful than electric models. They tend to be quite noisy, often requiring ear protectors to be worn, and aren’t great for the environment. As a result, they only really need to be used in more professional settings where this sort of powerful tool is required.

The Conclusion

Comparing mains-powered strimmers with cordless ones, some consideration will come down to personal preference; however, cordless strimmers are starting to dominate the market over mains-powered options and there are some pretty clear reasons why.

The battery run-time of cordless tools has greatly improved over the last couple of years, with the majority of cordless strimmers able to run for at least 30 minutes. Some have a run-time of up to an hour and, if you buy more batteries, you can swap them for charged ones to continue with the job. There are few strimming jobs that will really require more time than this, maybe cordless a no brainer for a lot of people.

Plus, the power capabilities of cordless strimmers are a lot better than they were. Now it’s not only petrol or mains-powered models that can cut through thicker undergrowth and weeds – a lot of cordless models can do this too.

Choosing the Most Comfortable Strimmer Design

Here are a few things to look out for when choosing the best garden strimmer for you:

  • Handles – an ergonomic handle is a great plus, and a second handle further down the shaft makes strimming much easier. The second handle balances out the weight to avoid ending up with one aching arm. The design of the second handle can differ, and some people find a real handle more comfortable than just a raised hand-hold.
  • Telescopic shaft – Adjustable shafts help you find the perfect working height and save on backache. More powerful strimmers should have a longer reach so you can hold them away from your toes. (This is a good place to say you should never strim the lawn in flip flops. Always wear sturdy boots!)
  • Auto-feed spool – this makes it easier to release more line when the existing line gets worn. You simply turn on the machine and new line is released. Other line-feed options include:
    • Bump-feed spool: you need to bump the head of the strimmer on the ground to release more line.
    • Manual spool: the user manually pulls the line out

Wearing the Correct Attire

Protective clothing such as ear defenders for louder, powerful motors can be useful, particularly if the job is going to take a while.

Sturdy boots are a must, and avoid wearing loose trailing clothes that could get caught in the strimmer.

If you’re cutting overgrown areas, protective glasses are important because strimmers can throw up stones and other sharp objects.

Strimmers and Wildlife

It would be remiss not to mention the injuries strimmers can inflict on harmless wildlife.

They are great bits of kit, but use them mindfully to avoid inflicting unnecessary damage and pain.

Always rake through long grass or undergrowth first, before using a strimmer. This gives hedgehogs, frogs, toads, grass snakes, newts, mice and all our native wildlife a chance to escape.

Bear in mind that creatures like hedgehogs would rather curl up to avoid danger, so watch what you’re doing and never put a strimmer somewhere you can’t see the cutting line.

Cordless Strimmer FAQs

How long can I realistically expect the battery to last on my cordless strimmer?

Naturally, battery run-time varies between strimmer models. However, the most common battery life for a cordless strimmer to have is between 30 – 40 minutes.

Battery life depends on the job you’re doing – if you’re simply cutting lawn grass where your mower can’t reach, you can expect to achieve the upper ends of the maximum run-time.

However, if you’re cutting through thicker undergrowth, and especially if you’re having to use a ‘turbo’ setting, you’ll use up the battery quicker – maybe even in as little as 20 minutes.

How do I replace the cutting line on my strimmer?

  1. Firstly, make sure the strimmer is unplugged or turned off.
  2. Next get out your spare strimmer line.
  3. Remove the casing and place the new strimmer line on the spool’s starter hole, winding it around the directional arrows.
  4. It’s worth taking your time to make sure it’s neatly done, otherwise the strimmer may jam and you’ll have to start again. When you reach maximum capacity, or come to the end of your strimmer line, cut it with around six inches to spare and fix the end into the spool’s eyelets.
  5. Then you’ll need to put the spool back in, making sure the strimmer line matches up with any outer eyelets.
  6. Finally replace the strimmer casing by lining up the tabs and pressing until it clicks.

It may take some time to figure this out as it can vary between strimmers, so always retain the instruction booklet. There are some helpful videos online too.

Which is better for releasing cutting line – a ‘bump feed’ system, or ‘automatic feed’?

A bump-feed system requires you to push the head of the strimmer into the ground to prompt more line to be released.

This gives you control over when more line gets used, but can sometimes be unreliable and difficult to use.

An automatic-feed system sees new line getting released automatically everything time the strimmer is turned on.

This is often quite reliable, but can result in line being used up more quickly than necessary.

If you’re worried about having to buy line more often, you might consider a strimmer with a bump-feed system. If that doesn’t concern you as much, and you just want the most straight-forward option, consider an automatic-feed system.
