worx hydroshot performance

The WORX Hydroshot is one of the most popular and well-known cordless pressure washers on the market.

It’s an excellent all-rounder that delivers in all the ways you’d expect. Out of the washers I tested, this comes out as the very best portable pressure washer.

It’s easy to assemble, and provides impressive power even when drawing from a portable water source. The construction is solid, it has a good range of spray angles and pressures to choose from, and it will legitimately clean almost anything.

I tested bikes, muddy boots, garden tools, our car, patio furniture, the wheelie bin and our windows. It cleaned them all with ease. The only things I don’t think it’s suitable for are my dogs paws (it’s too powerful) and patio algae (it’s not powerful enough for this).

Overall though, after testing a variety of models, I do believe it’s the best cordless pressure washer on the market and well worth your consideration.

Pros

  • Pumps out a lot of power even when drawing from a portable water source
  • One of the quietest pressure washers tested - shouldn't be too disruptive for neighbours or wildlife
  • 5 spray angles range from 'pencil' jet spray to a wider, gentler spray, so a lot of options depending on the job
  • Just one button to press to switch between high pressure and low pressure setting which is useful for saving battery life
  • Long 30 minute battery life is quite substantial for a batter-powered pressure washer

Cons

  • Can't be used to clean pets as there isn't an ideal spray setting - the jets are too strong, and the gentle sprays are too wide
  • Charge time is relatively long at 3 - 4 hours
  • Only the pencil jet is strong enough to remove thick algae, and it's not practical to try to clear a large patio area with such a narrow jet

Norse SK25i Portable Electric Pressure Washer Review

Tested by: - Read the Full Review

Specifications

  • Pressure (Bars): 25 bar
  • Water Flow Rate: 3 L/min
  • Battery Life: 15-30 mins
  • Weight: 1.5 kg
  • Charging Time: 1 - 2 hours

  • Spray Patterns: 4
  • Hose Length: 4 m
  • Water Tank: No

norse

With a team of Norwegian engineers behind its design, the Norse SK25i Portable Electric Pressure Washer is a very popular cordless pressure washer.

There’s a lot to like about this pressure washer, let down only by its poor battery life.

In terms of power, it’s one of the best cordless pressure washers available. The 25 bar water pressure is noticeably strong, suitable for tackling dried-on dirt, and when combined with the detergent bottle there isn’t much it can’t clean. Plus, the extension lance gives a really long reach, so it’s great for cleaning windows too.

The fact that the battery only lasts for 10 minutes of continuous use is a bit of a let down. You have to be quite methodical with your approach to tasks to make sure you get the most done in the available time. This is the compromise that you need to make when it comes to powerful cordless pressure washers – if they’ve got a lot of power, running time becomes limited.

If you want something that is both cordless and powerful, this is a great choice, and the short battery life is the price you pay. Otherwise, you’ll probably have to go for a mains-powered pressure washer if you want this level of power without the battery issue.

 

Pros

  • The 'turbo' setting produces a powerful spray that will remove small areas of algae and reach over 4 metres
  • A longer lance can be created by connecting both lances together, creating a long reach which is useful for jobs like cleaning windows
  • Included detergent bottle makes it easy to dispense soap at the same time as cleaning

Cons

  • It only has a short battery life of 10 minutes
  • The soap is used up from the detergent bottle quite quickly, so it may need to be refilled several times during one job
  • The jets are too strong to use for cleaning pets

Karcher OC3 Mobile Outdoor Cleaner Review

Tested by: - Read the Full Review

Specifications

  • Pressure (Bars): 5 bar
  • Water Flow Rate: 2 L/min
  • Battery Life: 15 mins
  • Weight: 2.78 kg
  • Charging Time: 3 hours
  • Spray Speeds: 1
  • Spray Patterns: 1
  • Hose Length: 2.8 m
  • Water Tank: Yes

karcher-2

The Kärcher OC3 Mobile Outdoor Cleaner is pretty unique in that it has a built-in water reservoir which is extremely helpful in certain situations, making it the best cordless pressure washer with a water tank. You can fill it up and then not worry about having to use an external water source. However, it does run out quickly.

I can see myself taking this camping to clean plates, wash off footwear, and clean the car window screen after a trip down a wet motorway. Basically – gentle tasks that don’t require a lot of power.

The nozzle has one spray pattern, whereas other machines have a variety of jets, so it’s not all that versatile.

This is not high-powered machine and it doesn’t claim to clean your patio. I think this cordless power washer is pretty good for its claims but removing dried mud and bird mess took a lot of soaking and the water ran out.

If you want something that will clean all your patio furniture, I’d look for another that uses an external water source.

This certainly has its place as a portable source of cleaning muddy paws and fresh mud. It’s not really the same product as others on this list so comparing them directly is unfair. The built-in reservoir is handy, but it’s not a ‘high-powered pressure washer’ in the traditional sense.

Pros

  • All of the parts can be stored underneath the removable tank for easy storage and portability
  • Suitable for low pressure tasks such as washing the dog and cleaning fresh mud off boots
  • The water tank can be filled and then clipped to the machine, meaning water won't spill and it can be put in the boot of the car
  • Relatively quiet - about the same volume as a hairdryer

Cons

  • Not a very high-powered machine - the jet is similar to a tap on full power
  • Gets through water quickly - the water tank will empty with two minutes of continuous use
  • There's only one spray setting with no additional nozzles

Specifications

  • Pressure (Bars): 22 bar
  • Water Flow Rate: 2 L/min
  • Battery Life: 30 mins

wesco-2

Next up, I put the Wesco WS8800 Cordless Portable Pressure Washer through its paces.

The best way to describe this cordless pressure washer is basic but powerful. It’s certainly capable of doing the majority of jobs that you would require from a cordless pressure washer and I think it’s the best budget cordless pressure washer.

It doesn’t have quite as much reach as some others – the jet itself doesn’t stretch quite as far, and there’s no extension lance, so it’s not quite so good for long-range jobs. In particular, it feels heavier than others, possibly down to its basic, non-ergonomic design. For this reason, it’s not quite as good for jobs such as cleaning the windows.

The fact that you sometimes need to stop to let the battery cool down is also a bit of a nuisance, it makes jobs take longer and you have to remember to keep an eye on it.

Also, other cordless pressure washers at the same price tend to come with more accessories, which I think Wesco should look to include to provide more value to the consumer.

Overall though, for the price-point I think it offers decent value for money and is a good cheaper option.

Pros

  • 15-minute run time is sufficient for car cleaning
  • The jet can reach 3 m and has a lot of power behind it
  • 6 m hose makes it easier to do long-range tasks without constantly having to move the water source
  • Capable of removing dried-on dirt along with fresh mud

Cons

  • Relatively long charge time of 1 hour 20 minutes
  • Feels bulky and heavy to hold above waist height making it more uncomfortable to clean some taller objects
  • The battery can get very hot and need time to cool down partway through a job

Yard Force Aquajet Cordless Portable Pressure Washer Review

Specifications

  • Pressure (Bars): 22 bar
  • Water Flow Rate: 4.5 L/min
  • Battery Life: 10 – 20 mins
  • Weight: 3.7 kg
  • Charging Time: 1 hour
  • Spray Speeds: 2
  • Spray Patterns: 3
  • Hose Length: 6 m

yardforce-2

The Yard Force Aquajet Cordless Portable Pressure Washer is a good cordless pressure washer that does that majority of cleaning jobs well.

It doesn’t have quite the same pressure as most of the other washers that I tested. However, with the help of the brush accessory it is capable of cleaning most surfaces.

The accessories are very good. From the machines I tested, I’d say this is the best cordless pressure washer for accessories. If you’re worried about accidentally removing car paint or breaking old glass, the additional brush allows you to clean more gently. The ECO mode also softens the pressure for a gentle clean.

I suppose the biggest downside is that most people buy a pressure washer so that they don’t have to get manually stuck in, so if you’re only wanting to clean from a distance (without using the brush) this may not be right for you.

Pros

  • The brush accessory is especially good for achieving a clean surface with no debris left behind
  • The ECO setting makes the jet softer, which means it is safer to use on car paint and windows
  • It's possible to change the angle of the handle to make it more comfortable to hold

Cons

  • The loudest of the pressure washers tested, emitting quite a loud screeching sound
  • Quite expensive for what you get, unless the detergent bottle and brush attachment are a priority for you
  • The trigger can be quite difficult to press and requires reasonable hand strength
  • Not enough power for cleaning tougher stains without the help of the brush attachment

How to Choose a Portable Pressure Washer

Written by:

A cordless pressure washer can help make life a lot easier (and cleaner!).

They’re particularly useful for taking with you on the go – on camping trips or walks – and for cleaning cars and bikes without being tethered to mains power.

There are a few things to bear in mind if you’re looking at buying a cordless pressure washer. Here are a few things to consider, to help you make an informed purchase:

What Do You Want to Clean With Your Cordless Pressure Washer?

This is something that’s important to consider. What do you want to use your cordless portable pressure washer for?

Some models are better suited to hosing down the bikes after going down a muddy trail, whilst others might be too powerful for this job. Equally, you might be keen to remove dried-on stains, in which case you’ll want a lot of power.

A washer with more than 22 bar should be capable of removing most types of dirt. A good pressure washer with this power can usually remove algae on patios using a fine ‘pencil’ jet.

If you want to use your cordless pressure washer for more delicate tasks, such as cleaning a grubby dog after a walk, you should look for something much gentler, around 5 bar.

Depending on how important portability is, you might want to look for a cordless pressure washer with a built-in water tank. Many of the best cordless pressure washers need an external water source – often this can be a bucket, bottle of water, or stream. However, there are some washers that can contain the water ‘on board’.

An on-board water reservoir will make the unit more compact, and quicker to use. For certain jobs, this could be desirable.

Finally, if you will be doing a lot of window cleaning with your cordless power washer, you will benefit from a longer reach. In this case you should look for a washer with an extension lance.

How Easy is it To Use?

With cordless power washers there are no cables to worry about tripping over or getting wet.

Their compact size also makes them easy to use. Standard mains power pressure washers can be quite heavy and get tiring. The best cordless pressure washers weigh between 1 – 4 kg and can be easily carried around.

Of course, there is still quite a different between 1 kg and 4 kg, so bear in mind what jobs you’ll be doing and how long you’ll need to hold it for.

When buying a cordless pressure washer, double check that it comes with a hose that will allow you to draw water from any water source not just a mains tap (of course, this doesn’t apply if it has a built-in reservoir).

Being able to carry around the washer and the water source, without being connected to any mains power or tap, makes a lot of jobs much easier.

If you want to take your cordless pressure washer in the car, and hose down your mountain bike or dog after a day of fun in the great outdoors, consider a smaller model which can be transported easily.

Remember, if it isn’t quick and simple – you won’t use it. If a model is too big or heavy, you might be put off using it often, even if it is powerful. Sometimes it’s better to go for a slightly lighter often, with marginally less power, if you’ll actually get more use from it.

You should also look for a cordless pressure washer that has a simple gun and various attachments. This will make it more versatile and mean you can clean different things. A fine mist, pulsating jet and pencil jet are really helpful.

Follow the care instructions carefully because these will extend its life. Pay particular attention to the advice about charging – overheating a battery does it no favours, and it may benefit from being charged before it has 100% run down.

Make Sure You Consider The Battery Power

Battery power is something you must consider with portable cordless pressure washers. There’s no way they can compete with petrol pressure washer or mains powered pressure washer when it comes to run-time and power. However, they can push out a fair amount of strength and come into their own in certain situations.

The biggest problem is always going to be how long the battery will last. This can vary quite dramatically between cordless pressure washers, and the charging time is also worth bearing in mind.

Using the tools featured on this page as an example, batteries may last for as little as 10 minutes, or a maximum of around 30 minutes. Portable cordless pressure washers with a shorter battery life may be more powerful, but you have to take a methodical approach to tasks to use them efficiently.

Remember: battery life only refers to the time when the washer is on. Washing the car might take a total of 30 minutes, but you may only sporadically use the power washer for 10 minutes of that time.

Some high-power washers have ECO settings which produce a lower-pressure jet. This allows their battery to last for longer and you can switch to high pressure only when it’s necessary.

Another option to consider is ‘interchangeable batteries’. Several brands, like WORX, have products that work on compatible batteries. This means you can use the same battery in your drill and your cordless pressure washer.

If you have any products from a particular brand already, it’s worth checking if their batteries are interchangeable. This would allow you to can charge one whilst using the other, and double the amount of time you can use the washer for.

Getting Enough Pressure to Your Washer

Too little pressure and the job takes hours, too much pressure and you can damage paintwork and pointing. Pressure is all-important when you’re trying to choose the best portable pressure washer for your needs.

By nature, cordless portable pressure washers have lower bar pressure than electric and petrol model. However, this ‘low’ bar pressure isn’t useless, and can even make them suitable for a greater range of jobs.

As seen with the products featured on this page, water pressure of 22 bar or more is enough for washing the car, removing dried-on dirt and general cleaning tasks. The only thing that isn’t possible is cleaning large areas of paving of built-up grime.

The benefit of cordless pressure washers, with their lower bar pressure, is that they tend to have a range of gentler pressure settings, so you’ll be less likely to damage paintwork with them.

It’s possible to buy cordless pressure washers with less pressure, of around 5 bar. These have the same pressure as a garden hose, but can still be useful due to their portable nature. Whereas you mustn’t use a 20 bar pressure washer to clean a pet, you could use a 5-bar option to hose them down.

You may have to get more ‘hands on’ with a lower pressure portable washer than you would with a mains-powered pressure washer. For example, using a brush attachment can help shift dirt.

How Easy is Transportation?

Not all of the best cordless pressure washers are as easy to transport as others. Most models are great for using around the house, but if you want to take them camping, or store them in the car, there are a couple of useful features to look out for.

Primarily, it helps if all of the attachments store on the washer itself.

When keeping items in the car boot for a long time, it’s easy for them to roll around and for small parts to get lost in the melee.

Finding a cordless pressure washer that stores all accessories ‘on board’ helps avoid this problem. Equally, you may find it easier if a water reservoir is also built in, so you can fill up with water before you leave the house.

Alternatively, of course, you can buy a jerrycan for a few pounds to store water in, and a clip box can keep the accessories from rolling around in the car boot. So there are solutions!

Portable Pressure Washer FAQs

I don’t have an outside tap or garden hose – can I still use a cordless pressure washer?

Yes. You can use a cordless pressure washer. You don’t need to connect them to a constantly flowing water source. With a cordless pressure washer you can either fill up the unit’s water tank (if it has one), or rest its hose in a body of water (bucket, water bottle, lake, etc.).

Jut make sure when buying a cordless pressure washer that it has the right hose included to allow it to ‘draw’ water from a static external source.

Can I use my cordless pressure washer in the winter?

You can use your cordless pressure washer if the temperatures are above freezing. Don’t leave the machine outside for long in winter. If temperatures are likely to fall below freezing after you pressure wash, you should make sure to dry the surfaces that you have cleaned (particularly if you cleaned your car) thoroughly.

Don’t leave your cordless pressure washer anywhere that it can get too cold, and make sure that all the components are dry before packing it away. If there is still water in the machine and temperatures drop below freezing, ice could form inside and damage it.

Can I wash down my dog with a cordless pressure washer?

Be careful when giving your dog a bath with a cordless pressure washer. Some jets are way too strong and will be dangerous.

A 5-bar pressure washer should be gentle enough for cleaning your dog, but anything higher may be too powerful. You must test the spray on your hand first, and this will help you tell if the jet is too strong or not.

If you have a sufficiently gentle portable power washer, it may have a built-in water reservoir. You can fill these with warm water to wash your dog, so that it doesn’t get cold.
