We all love how powerful and convenient pressure washers are, but there are going to be times when a cordless pressure washer will become very useful. The spring and summer seasons of the year are perfect for getting these items out, and they’ll offer an advantage on the potential of a hosepipe ban.
They’ve happened across the UK in previous summers, and fines can go up to £1,000. However, the neat trick of a cordless pressure washer is that you can feed the hose into a bucket of water and clean your car as normal. No continuous running water is needed, and our experts have employed this method to great effect when testing cleaning products on cars.
Best cordless pressure washers tested 2025 at a glance
These battery-powered gems give you the freedom to work anywhere and not be reliant on a plug. Cordless pressure washers use water much more efficiently and do not need a hose to feed in water. What’s more, a lot of these items are very compact as well – making thing easier for storage.. Inevitably, you won’t get the same performance as you would from a corded machine, but you may be surprised at how powerful they can be.
How we test the best cordless pressure washers
Cordless pressure washers are some of our favourite things to test here at Parkers. Each example we test, we test to its limits. Using a selection of dirty cars available, we park them as far away from taps and power as possible to see just how portable they are. Each car will be daily-driven and the perfect testbed for the different types of dirt you’ll need to wash off a car.
Battery-operated units will often struggle to clean compared to a traditional pressure washer, but cleaning ability is crucial for a good pressure washer. We still want it to be capable of cleaning a car thoroughly.
Ease of use is the trade-off you get for less pressure and is crucial for making a cordless pressure washer worthwhile. For this versatility and portability are what we’re looking for. Battery life, durability, and ergonomics are also assessed here.
Value for money is another top consideration for cordless pressure washers. They’re often more expensive than a comparative traditional unit thanks to the cost of batteries and so they really have to work hard to represent the absolute best value for money.

Verdict
The Worx Hydroshot Nitro WG633E is the winner by a country mile here. No other cordless pressure washer can match it for cleaning performance or versatility. If the price is simply too much, the non-Nitro Worx Hydroshot is a top choice, just less powerful.

The best cordless pressure washer
With a silky-smooth motor operation that feels more comfortable than any similarly-priced Karcher, the 4.0Ah battery can last well-over an hour in a standard cleaning procedure (tested) and you get an array of useful nozzle settings for different cleaning tasks, from general to precision tasks. The six metre hose should be enough for most situations.
Take this head-to-head with a budget corded pressure washer and the results won’t be too different. It outclasses every other portable pressure washer we’ve tried, and we still regularly rely on it for cleaning the press cars on test. If Worx weren’t so stingy with the included attachments, this would almost be without fault.

Editor's pick
There’s more to like with this budget-oriented Worx, too. It retains all the good ergonomic touches of the Nitro, making it easy to use and lightweight. The hose length is the same, the excellent 5-in-1 nozzle is kept, and every bit feels like it’s a quality item. It’ll even accept the same batteries as the Nitro. Worx’s battery-sharing technology is some of the best we’ve ever tested for runtime, which does present this kit as a bit of a bargain.
If you only ever need something for light cleaning or want to save some cash without compromising on quality, this Worx really cannot be faulted.
Review by Ryan Gilmore
Pros
- Great Worx build quality with sturdy materials included
- Smooth running operation, as per Worx products
- Six-metre hose included, which is nicer than the average five-metre hose
Cons
- 2.0Ah battery won't last as long as the 4.0Ah unit included with the WG633E
- Half the pressure of the WG633E

The best budget cordless pressure washer
It also has a five-metre hose, which is the standard for most units, so it's very nice to see a cheap option have that feature. And from what I could tell, it's the only cheap-feeling component of the machine itself. Everything from the battery locking mechanism to the nozzle feels quite chunky.
It's not as powerful to use; the pressure tops out at 15 Bar. But on our test, it turned out to be a wonderfully easy-to-use and easy-to-assemble tool that proves to be a very decent upgrade over your standard hose. It's more capable than I expected to get the remaining soap and dirt off a car. There isn't anywhere near as much flow rate as the others, but it doesn't matter as it's a lightweight, portable, and long-lasting machine that can stand its own ground against the establishments.
Review by Aaron Hussain
Pros
- Better build quality and feel than we expected, bar the cheap-feeling hose
- Very quick and easy to assemble and use, unlike others that require construction
- Great value for money at under £70
Cons
- The power and flow rate is compromised compared to others
- The battery life is much shorter than the Worx machines, which is to be expected

The best value pressure washer
The pressure varies by twisting the nozzle's spray pattern, unleashing 16bar / 232psi. While not a match for our class leader, this is still five times the pressure of a garden hose. It came with a six-metre hose to provide a water supply from a bucket of water. I cleaned a moderately dirty Ford Fiesta with 25-litres of water, plus another bucket for the car soap clean stage - so it's worth bearing this in mind if you are far away from a tap.
I found that Draper's supplied snow foam lance sprayed the foam on rather thinly, but this could be due to the amount of concentrated detergent I used. Overall, this is a well-made cordless pressure washer from Draper, with a good supply of standard accessories, with further reassurance given by its 24-month warranty.
Review by Dave Kirby
Pros
- Well thought out design and supply of lances and accessories
- Fast battery charger doesn't keep you waiting long before use
- Six metre hose better than the five metre average
Cons
- Lower pressure rate compared to others
- As with all cordless pressure washers, you'll make regular bucket refills
The best soft cordless pressure washer
In practice, however, it was hopelessly outclassed for cleaning a car. Even in the strongest setting, it failed to chop through mud and grime like the competition. It was more suited to bikes and wellies than to car care. There are three pressure modes, with 20 bar the maximum, and all of them were simply too weak to properly clean muck off a car.
I’ve concluded that its best use is as a massive powered watering can. With the 15-litre tank brimmed and an outstanding 60-minute runtime from the battery, you’ll be able to water the plants easily. The pressure can be made so weak that even the most delicate of petals won’t be harmed, so you’ll be able to trundle around, happy at not having to drag a big hose up and down the garden.
Review by Ryan Gilmore
Pros
- Water tank included
- Snow foam attachment included
- Long run time
Cons
- Too weak for properly mucky cars
- It's heavy when brimmed
| Max pressure | 20 bar/290psi |
| Max flow | 186 litres per-hour |

The best cordless pressure washer for lightness
When we tested it, it impressed us mostly too. It was lightweight and easy to hold for long periods. And despite the cheap-and-cheerful pricing, it never felt or performed like it was a budget piece of kit. The stand-out feature had to be the Turbo mode which helped it chop through mud during our testing at the expense of the battery life.
The design wasn’t quite as refined as the Worx. It would constantly topple over during testing, but that was a small fry issue compared to the motor, which burnt out a year into my testing. The smouldering motor was a huge disappointment in what ought to have been the best budget cordless pressure washer. The batteries have lasted well, however, and I still regularly use them with the rest of my Ryobi tools.
Review by Ryan Gilmore
Pros
- Lightweight design, weighing in at 3.3kg
- The Turbo mode helped with tough dirt
- Part of the excellent Ryobi battery sharing range
Cons
- A couple of design quirks make cleaning less fun
- The motor burnt out after a year
| Max pressure | 22 Bar |

FAQs and what to consider with cordless pressure washers:
Is a pressure washer worth the money?
Our answer is a simple yes. There are plenty of great cordless pressure washers out there. They range from budget units to more powerful ones like the Worx Nitro Hydroshot WG633E. When you don’t have access to running water, they can really be a time and life-saver, depending on your home and/or work situation. The only real drawback is the charge anxiety when using it, which you don’t get with a corded unit.
Are cordless pressure washers any good?
Once again we would say yes. Cordless pressure washers are convenient to use, especially for smaller tasks, and are versatile enough to be used for a number of jobs. The biggest advantage of a cordless pressure washer is the fact they are portable, so you can use them even if you’re struggling for mains power and a water supply.
There are some drawbacks, however, as cordless pressure washers generally can’t match the pressure that you’ll typically find in traditional pressure washers. Battery life is also something that you should consider when looking for a cordless pressure washer.
How do pressure washers work?
The clue is in the name – they use electrical energy from a battery or a mains power source to engage the motor, which powers a pump. The pump then pressurises the water to shoot through the high-pressure hose and out of the nozzle.
That high-speed blast of water lifts dirt, grime, and other unsightly mess from your car. For most people, having a good-quality pressure washer is essential for maintaining a car’s clean exterior.
Are pressure washers safe to use on cars?
Yes, they are, but only if used correctly. There are a number of things that you must consider before pointing the nozzle at your pride and joy:
Nozzle – The most important aspect of cleaning your car with a pressure washer is choosing the correct nozzle. Some nozzles will shoot water out at a higher rate at a more localised spot. While this is great to lift stubborn dirt when washing a garden fence, for example, it might not be suitable for your car as it can strip away paint. Always test the nozzle before applying it to your car.
Spray angle – Sometime you might need to use a high pressure nozzle to remove tough dirt, but we recommend you always use a shallow angle when pressure washing your car as it is less harsh on paintwork. It allows excess pressure to be directed away from bodywork.
Distance – If you use a pressure washer with high pressure then be sure to wash your car from a distance. This works by allowing the water to lose some momentum before it reaches your car, and therefore being less harsh on paintwork.
Other things to consider include the shampoo or product you use to clean your car, the temperature of the water, and parts of the car that can be easily damaged, like wing mirrors.
What should you look for in a cordless pressure washer?
Pressure and Flow Rate: Look for a washer that provides sufficient pressure and flow rate. Higher pressure and flow rate generally result in more effective cleaning, but will use more water and battery power. The battery life should be capable of providing enough runtime to complete your cleaning without frequent recharging. However, if this is an issue and you’re worried about cord length on a traditional pressure washer, outdoor waterproof extension cables are a solution.
Portability and Weight: Cordless pressure washers should be lightweight and easy to carry around. Look for ergonomic designs and features like wheels or handles for the best portability.
Water Storage: Do you need an onboard water storage tank, or will you have access to a water source?
Nozzle Options: Different nozzle attachments provide various spray patterns and pressure levels for different jobs. A wide-angle nozzle is ideal for general cleaning, and a narrow nozzle works best on more focused areas or stubborn marks. Aftermarket pressure washer attachments may not be much use with these specialised tools.
Can pressure washers remove stains?
Yes, pressure washers can remove stains from a number of surfaces thanks to the high-pressure, but we’d recommend caution when using a pressure washer on paintwork. When using a pressure washer to remove stains from your car you should apply the appropriate cleaning products.
What’s more important: power or water capacity?
Arguably, we’d say power. The point of a pressure washer is to provide a lot more of it than your standard hose in order to enhance your car cleaning experience. The Worx WG633E is the perfect example; it provides up to 56 Bar of pressure which is around ten or 11 times as much as a standard garden hose/tap.
This will make an obvious difference to the consumer who has to clean their car. Suddenly having the wrath of power will lift off dirt and grime like never before. Water capacity, assuming there’s some kind of hosepipe ban in place, will depend on the size of your bucket that you’re running the water from.
What PSI pressure washer is best for home use?
You will have noticed we’ve been using the Bar measurement when it comes to pressure. This is the unit that manufacturers like to boast about, and put simply, one Bar of pressure equates to 14.5 PSI (Pounds per square inch). Based on our impressions of the Worx Nitro Hydroshot which generates 56 Bar of pressure (812 PSI), we’d say that would be more than enough – and will provide enough pressure when a snow foam lance is attached. A lot of soft pressure units will have around 72 PSI which is more useful for lighter home jobs.
