The team at DIY Garden have spent hours putting the best cordless strimmers to the test. Not only did we analyse their performance when cutting lawn edges, but we also put them up against thicker weeds and vegetation too. Each strimmer battery was also tested, from its charging time to how long it ran for. Finally, we assessed their weight, noise levels, key safety features, and value for money too. The results are in and this is what we discovered…

WORX-GT-3.0-Cordless-Grass-Strimmer-review-performance

WORX is known for producing high-quality garden tools, one of which is the GT 3.0 Cordless Grass Strimmer. A 2-in-1 tool that also has an edger function, this strimmer is packed with features and also marked at a reasonable price. 

The WORX GT 3.0 required very little assembly – it was up and running in less than five minutes. However, you may want to spend a little more time exploring its many adjustable features – from the shaft, to the handle, to the angle of the head – these can all be altered to make the strimmer as easy and comfortable to use as possible. 

Whilst the strimmer felt lightweight to hold, its power was evident as soon as it was turned on.

It handled the easy stuff (long grass and light weeds) without a problem, but did struggle with thicker vegetation. However, you’ll still be able to strim dense areas by cutting thicker stems in two or three sections (rather than in a single swipe) – it’ll just take a little longer. 

The battery that came with this cordless grass trimmer had a run time of around 30 minutes, but you can’t expect too much from a 2.0Ah battery. The fact that it charges in just one hour is a huge plus, and you always have the option of purchasing a larger battery. 

The WORX GT 3.0 would be considered a mid-range cordless trimmer. It costs a little more than some of the budget options, but it’s not as pricey as high-end models. Nevertheless, it offers just as many, if not more, features as several of the high-end strimmers out there. For this reason, it’s one of the best cordless strimmers overall.

Even if you don’t use the edger function very often, the adjustable design, push-button cable feeder, and sheer power of this strimmer make it a worthwhile purchase for gardens of all sizes.

Pros

  • Adjustable shaft, handle, and head makes this cordless strimmer more versatile, as well as comfortable to use
  • The 2.0Ah battery charges in just one hour
  • Has an edging function that works well on lawns
  • Can cope with all types of vegetation - long and short grass, light weeds, and thick vegetation
  • Lightweight at 2.4 kg - it won’t leave your arms aching!

Cons

  • Thick vegetation needs to be cut down in 2-3 sections, which takes a lot more time
  • The 2.0Ah battery only lasts for 30 minutes - you’ll need to purchase a larger battery if you want to strim for longer

Einhell GC-CT Cordless Grass Strimmer Review

Specifications

  • Weight: 1.77kg
  • Cutting Width: 24cm
  • Battery Included?: Yes
  • Charge Time (Minutes): 120 mins
  • Max. Running Time: 55 mins
  • Battery: 2.0 Ah Lithium-ion

Einhell-GC-CT-Cordless-Grass-Strimmer-Review-performance

The Einhell GC-CT Cordless Strimmer comes with a 2.0Ah battery. Manufactured in Germany, this strimmer has been designed to keep lawn edges and flowerbeds tidy, whilst enabling you to cut hard-to-reach areas of your garden.

Assembling this strimmer only takes a few minutes. It’s been designed well, although the adjustable shaft isn’t quite long enough for tall people like myself – I had to stoop while strimming. 

This strimmer cuts using plastic blades instead of a cutting line. However, this doesn’t seem to put it at any sort of disadvantage – it copes well with long grass, docks, nettles, and brambles. Even though it hasn’t been designed to cut thick vegetation, it’s powerful enough to do so. The blades are sufficiently flexible not to snap easily, even when up against vegetation that this strimmer can’t hack

Even better, this is a very lightweight grass trimmer. It can be used continuously for long periods of time without tiring the arms. However, you’ll need to purchase a larger battery to be able to use it for more than a 45-minute stretch. 

Although I never really thought much of plastic blade strimmers in the past, I have to say that I’m a convert – especially when you can purchase one that’s this good for such a reasonable price.

Overall I have to say that this is one of the best lightweight cordless strimmers available. It offers great value for money and is ideal for small to medium-sized gardens, even if you have thick vegetation to occasionally strim. It’s able to cope with more than it says it will, which is particularly impressive considering its light construction.

Pros

  • The lightest cordless strimmer we tested, weighing just 1.77 kg, which makes it easy and comfortable to use
  • Has an adjustable shaft that will suit people of varying heights (although it isn’t quite long enough for those over 6 feet) and enables you to strim hard-to-reach areas
  • Can cope with all types of vegetation - short grass, long grass, light weeds, and thick vegetation
  • Blades don’t break easily, which saves having to replace them often
  • This grass trimmer can be used with all Einhell Power X-Change lithium ion batteries

Cons

  • Thick vegetation needs to be strimmed in sections, which takes longer
  • Doesn’t have a safety button to press alongside the trigger, meaning that the strimmer could easily be accidentally turned on
  • Tall people will need to stoop when strimming, which can get uncomfortable

Ryobi-One+18V-Cordless-Grass-Strimmer-Review-performance

There are several products in Ryobi’s One+ cutting tool range, one of which is their RLT1825M20S ONE+ Cordless Grass Strimmer. Strimming isn’t a task that I particularly love doing, but hearing that this strimmer has been designed to make strimming easy and effortless gave me high hopes for how this product would perform. 

Upon opening the box, you’ll see that there are only a few components to assemble, which is a good thing since the instruction manual isn’t very clear. Assembly is relatively simple and only took me about 10 minutes. 

In general, there’s a lot to say about the design of this cordless grass trimmer –  it’s all been very cleverly thought out. Just about everything is adjustable – the handle, the head, and even the cutting width (25 cm or 30 cm), which is a feature that most other cordless strimmers don’t offer.

All of this great design meant that I had high expectations when I first gave the strimmer a try. It cut grass well, both short and long, and didn’t have a problem with light, mostly dried weeds either. However, it really struggled with thicker weeds. This isn’t the strimmer to choose if you’re planning on clearing dense and overgrown vegetation. 

I also noticed that this strimmer didn’t feel quite as powerful as some of the others that I tested. It came with a 2.0Ah battery, which gave me about 20 minutes of strimming time. This may be all you need if you have a small garden, but I would recommend purchasing a larger battery for medium or large spaces. 

When you consider its many features, this cordless grass trimmer comes in at a fair price. However, as mentioned, if thick weeds are what you need to cut, then you’d probably find this strimmer to be a waste of money. On the other hand, if you only need to strim grass and light weeds, then this is one of the best cordless strimmers for the job. It will not only hold up well, but it’ll also make the task easy, comfortable, and relatively enjoyable!

Pros

  • Adjustable handle, cutting head, and cutting width gives the strimmer more versatility, and makes it comfortable to use
  • Auto-feed line feature releases more line each time you lightly pull the trigger, saving you from having to pull more line out manually
  • This grass trimmer has an edging function to keep lawns looking neat
  • Lightweight at 2.1 kg - doesn’t require the use of a harness

Cons

  • 2.0Ah battery only lasts for 20 minutes (but larger lithium ion batteries can be used if you need to strim for longer)
  • Struggles to cut thick vegetation, such as docks, brambles, and thick nettles
  • Doesn’t feel as powerful as some of its competitors

Bosch-Advanced-Grass-Cut-36-Cordless-Strimmer-Review-performance

Bosch is a brand that just about everyone knows and loves, so I had high hopes for the Bosch Advanced Grass Cut 36 – a cordless grass trimmer and edger that’s designed for long grass and overgrown areas. 

Assembling Bosch power tools is usually a simple task, but this cordless trimmer required quite a bit of strength to put together. As long as that’s not an issue for you, assembly should only take about 15 minutes.

From its colours and design to its numerous features, everything about this strimmer screams Bosch. In my eyes, that’s a good thing – this is a brand that has a solid reputation for quality and reliability. 

However, I have to admit that I was a little disappointed by how this strimmer performed. It has supposedly been made for long grass, yet got quickly tangled which caused it to choke. It does well on short grass and most weeds, including brambles and docks, but struggled in thick patches of nettles. 

Having a battery life of just 35 minutes also limits you if you need to strim large areas. The semi-automatic line-feed function stops working once the battery light is down to its final bar.

That said, you could easily swap out the 2.0Ah battery for something more powerful, which is especially easy to do if you already own other battery-powered Bosch tools. 

This strimmer’s weight is both a pro and a con. At 4.1 kg, it feels solid and sturdy. However, it’s also the heaviest of the cordless grass trimmers I tested – you’ll need to purchase a shoulder harness for long periods of use. 

All in all, I expected more from this strimmer. There are cheaper alternatives out there that offer more features and do a better job. That said, if you already own a more powerful Bosch battery, not only could you cut down on costs, but you could significantly extend the strimmer’s running time, which would be a big bonus.

If you have a small garden, I would recommend going with a more cost-effective option. However, if you’re a Bosch fan, this could be one of the best cordless strimmers for medium or large gardens – especially if you can upgrade the battery.

Pros

  • Has an edging function to keep lawns looking tidy and defined
  • This grass trimmer cuts short grass and most weeds well
  • Can be used with any Bosch battery, which is useful if you already own battery-powered Bosch tools
  • Has a semi-automatic line feed function that releases more line each time you pull the trigger, saving you from having to check the cable as you’re strimming

Cons

  • Priced significantly higher than its competitors, yet doesn’t have quite as many features as other cordless grass trimmers
  • Heavy at 4.1 kg (can be used with a harness, but doesn’t come with one included)
  • This was the only strimmer we tested that choked in long grass
  • The semi-automatic line feed function stops working once the battery is down to one bar - you’ll need to pull more line out manually

Terratek-Cordless-Grass-Strimmer-Review-performance

Terratek is known for producing quality tools at low prices, resulting in the brand building up a loyal following over the years. Compared to its competition, the Terratek Cordless Grass Strimmer is at the lower end of the price scale, yet it still promises to make light work of cutting grass and weeds. 

If minimal assembly appeals to you, then you’ll love this strimmer. It’s pretty much already assembled – open the box and you’ll have the strimmer up and running in less than five minutes. 

Overall, there’s no denying that this strimmer’s design is impressive. Granted, at first glance, it may not look particularly exceptional, but take a closer look and you’ll see that numerous features have been crammed into this compact tool.

You can adjust the shaft, handle, and head, and it also has an edging function. It also has a satisfactory cutting diameter of 25 cm. The only downside is how flimsy the plastic blades feel, although I tried to remain optimistic that they’d be up to the job. 

Unfortunately, I was right to have doubts about the strength of the blades. They worked well on grass, both long and short, dry and damp, but struggled big time when it came to weeds.

This strimmer can cut back the occasional thin weed, such as a spindly willowherb or nettle stalk, but it left thicker weeds standing. What made this even more frustrating was that the blades would easily snap, or spin right off and disappear into the vegetation, when they came into contact with a thick weed. 

While I was disappointed with the strimmer’s ability to handle dense vegetation, its battery life impressed me. It came with two batteries, each one 1500 mAh. I didn’t expect much from them, but each one lasted for 30 minutes – just as long as larger batteries from other brands. The fact that there were two of them meant that this strimmer gave me the longest run time of all (an hour in total).

Being a lightweight strimmer, with so many adjustable parts, the Terratek cordless strimmer was easy to use. However, it does vibrate considerably, which is a concern. Products that vibrate a lot, and are used frequently, have been known to cause a medical condition called vibration white finger.

To conclude: when it comes to features, this cordless grass trimmer offers great value. However, the blades aren’t good quality, and replacement blades can be expensive, which isn’t ideal for those who plan on using this strimmer regularly.

The fact that it also struggles with thick weeds could be a problem for some, but I would say that it’s one of the best cordless strimmers to help with managing grass in a small or medium garden. If you only need something light, for occasional use, then the Terratek Cordless Strimmer offers good value, especially due to its long battery life.

Pros

  • Easy assembly means that the grass trimmer is up and running in less than 5 minutes
  • Adjustable shaft, handle, and head makes the strimmer more versatile in the garden, as well as more comfortable to use
  • Comes with 2 x 1500 mAh batteries, which, together, run the strimmer for longer than the larger 2.0Ah batteries from other brands
  • Cuts grass well, whether this is long, short, wet, or dry
  • Lightweight at 2 kg - you won’t need a harness to comfortably use this strimmer

Cons

  • Doesn’t strim thick weeds, such as docks, brambles, and thistles
  • Blades are flimsy, break very easily, and replacement blades aren’t cheap
  • Very strong vibration makes it uncomfortable (and potentially dangerous) to use for long periods of time

How to Choose a Cordless Strimmer

Written by:

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 grass trimmers 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 be a lot of effort. By comparison, a cordless strimmer save a lot of hassle. Ultimately, if the strimmer is easy to use, you’ll be more likely to get it out the shed.

If you’re after a new cordless grass trimmer, there are a few things to bear in mind to make sure you’re getting the best one. The information below should give you an idea of what to look out for, and also what to avoid:

How Grass Trimmers Work

Grass trimmers tend to use one of two cutting mechanisms: a cutting line, or cutting blades.

Here’s a description of each type, as well as their pros and cons.

Cutting Line Strimmers

Strimmers that use a cutting line have one or two lines of nylon string inside the head of the strimmer. They cut using centrifugal force; whilst the line is no good for cutting when at rest, it becomes stiff and blade-like when it spins quickly.

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’.

Strimmers with a ‘bump feed’ system require you to ‘bump’ the end of 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 it is used.

‘Automatic feed’ strimmers release more line each time the machine is turned back on. This can help ensure you’re never using weak, blunt line. However, it can sometimes result in using line too fast, which becomes expensive. If you’re using a cordless grass trimmer, you’ll likely keep turning off the unit to save battery as you move around the garden. It can therefore be wasteful if new line is automatically released each time you turn the unit on.

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

There are also single-line and double-line strimmers. Single-line strimmers have less cutting force than double-line strimmers, but that isn’t necessarily a bad thing. It just depends what job you are doing. Some people find that a grass trimmers with a double cutting line is too strong: they can damage tree trunks, flower pots or fencing if you get too close.

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 speed. As they spin, they generate a lot of cutting power.

The blades are replaceable, and generally you’ll need to replace a blade after every 2 hours of 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.

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 grass trimmer is quite intuitive. There is usually a simple start button which will start the motor going. Some machines have a safety button as well as a start trigger, requiring both to be pushed to avoid accidental start-ups.

It may take a bit of practise initially, as well as trial and error, to work out where the cutting line is, but it doesn’t take long to master.

One side of the grass trimmer 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. With tougher plants, it can help to tackle them in sections. If a strimmer can’t immediately tackle the thick stem of a weed, it can help to cut from the top down and cut it gradually.

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. It’s best to clear the parameters first, just to be sure.

Why Choose Cordless Over Mains Powered?

Cordless battery-powered strimmers and mains-powered strimmers work well in the garden. Petrol models are also available, although they’re less commonly used for domestic use so here we’re going to focus on electric models. There are pros and cons to cordless and mains-powered strimmers, which are covered below:

Mains Powered Strimmers

Mains-Powered grass trimmers are powerful and there’s no battery to run down – their run-time is essentially limitless. They can often cut through slightly thicker vegetation than battery-powered models.

However, these strimmers can cause problems sometimes. Some people worry about cutting through the cord with the strimmer, which is easier to do than you might think. Also, as mentioned 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 larger than a small garden, or for reaching awkward places, an extension cable will be needed. This can be a hassle, as well as a tripping hazard.

Cordless Strimmers

Battery-powered strimmers have a limited amount of run-time before you need to stop and charge them. However, how long the battery lasts for depends on its size and power. Some cordless grass trimmers will have a battery than only lasts 20 minutes, but others (normally with a battery of 4 Ah or more) can last around 30 – 40 minutes depending on the job.

Naturally, one of the main benefits of a battery-powered strimmer is that they are 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.

The Conclusion

As with a lot of things, personal preference will likely dictate whether you choose a mains-powered or battery-powered strimmer. It also depends on the job you are doing, whether you need slightly more power with a mains-powered option, or prioritise the freedom of cordless tools.

In terms of power, there is now some crossover between battery-powered models and mains-powered ones, especially in the mid-range price bracket. So, the biggest caveat is the battery run-time of cordless strimmers. This is something that has greatly improved over the last couple of years, so it’s best to look for a tool that has 30 – 40 minutes run time. 20 minutes may not be enough. Of course, if you buy more batteries, you can keep swapping them out to continue with the job. There are few strimming jobs that will really require more than an hour’s work, making cordless a no brainer for a lot of people.

Choosing the Most Comfortable Design

Here are a few things to look out for when looking for a garden strimmer

  • 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!)
  • A cutting style that you get on with – as mentioned above, strimmers can use either cutting line or cutting blades. Keep this in mind when shopping, and decide if you’re more comfortable (physically and economically speaking) replacing line or blades when it wears 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. This is particularly relevant for petrol machines, but certain electric motors can also be very loud.

Sturdy boots are a must, and you should 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.

Wear gloves to protect your hands whilst strimming, and be aware of the need to take frequent breaks – especially if the machine vibrates a lot.

A Warning About 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 grass trimmer?

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 grass trimmer?

  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.
