Best pressure washers – tried and tested reviews

Best pressure washer overall

Max out on power and capability with the Karcher K4 Premium High-Pressure Washer, which aced our at-home tests. This super versatile pressure washer is fully equipped to deal with a range of problems that might arise after a winter in the UK – we’re talking lacklustre garden chairs, clogged gutters and sad-looking BBQs.

To tackle these tough jobs, our reviewer powered through the three pressure settings on the K4, using each of them to blast through dirt and grime and get surfaces back to their original colour. When using this pressure washer, our expert found the trigger handle display which clearly shows which setting you’re on especially useful.

This sturdily-built washer is kitted out with everything you need to sort out both your garden and your car, and enabled our reviewer to easily clean her glass patio doors, car, stone patio and wooden sleeper pathway. With an RRP of £399.99, we know that this is a real investment, but if you want a pressure washer built to last that can take on practically any of your surfaces, and make your car gleam too, then you’re onto a winner.

Best multipurpose pressure washer

You can’t go wrong with Nilfisk’s Excellent 160-10 pressure washer. Ideal Home‘s Senior digital editor, Jenny McFarlane, reviewed it at her Belfast home. She found it a powerful mid-range machine that made light work of her patio, car and kids’ outdoor toys.

It requires minimal set-up and is super efficient in removing dirt and grime from all of the grotty surfaces she used it on. Including a multipurpose gun and lance, Nilfisk’s Excellent 160-pressure washer can tackle anything from cars and bikes to cleaning garden furniture and barbecue grills with its arsenal of handy tools.

The Power Foam Blaster creates a rich lather to get your car pristine, while the Mid Patio Cleaner will make small work of cleaning large areas such as patios, driveways and wooden decks. The variety of attachments available helped to give more control to the cleaning tasks whether you need a powerful stream of pressure or something more gentle for the car or windows.

Powered by a low-noise, 2100W induction motor and a longer-lasting metal pump, it’s super easy to move about with its telescopic handle and trolley. Although it could be a potential trip hazard, the 10m long Ultraflex hose reduces kinks and knots and is easily wound up inside the machine after use.

Best cordless pressure washer

Do you think you need to have an outdoor tap or nearby plug socket to use one of the best pressure washers? Think again. This pressure washer from Worx makes cleaning outdoors much more accessible thanks to the portability features that make it a totally ‘ingenious’ buy, according to our reviewer.

In short, you can fill it up using a nearby bucket or water butt, and battery power eradicates the need to be dictated by a plug or cord length. Even better, you can actually use a draw hose and soda bottle with this washer, and take it wherever you need to clean up outdoors.

This is a lightweight, compact tool, and while it is perfect for smaller jobs (especially in larger gardens), it won’t quite hit the mark if you need a heavy-duty pressure washer for big patio cleaning jobs, for example. If you already own Worx products, you’ll be happy to know that this tool is part of the Worx PowerShare system, so that you can use the battery across other garden tools. Our reviewer and garden expert Rhoda Parry found that the battery lasted for around 30 minutes of pressure washing, which is plenty enough for smaller jobs.

Best small pressure washer

This versatile, compact pressure washer is not only budget-friendly, but also a total all-rounder. Ideal Home’s Editor Heather Young has been testing the Karcher K2 out for some time now, saying that while it’s ‘small and compact, it doesn’t compromise on power.’

Heather loves using the K2 in her garden as part of a clean-up operation after gardening work – especially after wet weather. Her patio has been cleared of mud thanks to this pressure washer, and the compact nature of the K2 means it’s a breeze to get out and pack away again, even for small jobs. Heather says that she’s more inclined to use the K2 than her full-sized pressure washer, thanks to just how convenient it is.

Pet owners can also trust the K2 to help them get rid of pesky muddy paw prints across the garden, as well as for smartening up their car or garden furniture. For portability, look no further than the built-in wheels, five-metre cable and extendable handle.

While this is a great value choice for smaller jobs and gardens, it has to be said that the K2 probably isn’t the most capable choice for expansive patios or walls. For quick and easy use though, it’s a total star.

Best affordable pressure washer

If you want to tackle your patio or decking on a budget, then the Bosch Aquatak 110 might just be the ideal remedy to your dirt and grime problems. For under £60, this small corded pressure washer can help you clean up your driveway without issue, even if it’s not fully equipped for bigger jobs (like freshening up your home’s exterior or car).

Yep, if it’s small jobs you need to complete, then that’s where the Bosch Aquatak excels. This model is currently being tested by our garden expert and reviewer Rhoda Parry, but user reviews online are mostly positive about this washer. On B&Q, it scores 4.5 stars out of a possible five, generated from 46 user reviews. While there are some reports of a lack of quality, on the whole, customers are happy with their purchase.

One reviewer comments that ‘This machine had good reviews and lived up to them. This is for our decking and patio/drive. So no large jobs. The instructions are good. Easy to our together and light to use. I have mobility issues, so ideal’. Our full review of this washer is coming soon, but for now, this washer sounds like a solid bargain buy.

Best heavy-duty pressure washer

The Stihl RE 120 Pressure Washer is an admittedly expensive buy, with a price tag of £420.00 (though you can find it elsewhere for less) but our expert reviewer Linda Clayton stands by the fact that it’s a value-for-money buy if you can afford it. This ultra-capable pressure washer aced almost every test Linda threw at it – she’s confident that it can transform any outdoor space.

She used it across her home to bring various areas back to life, including her patio, slate slabs and steps, outdoor furniture, glass divider, and stone brick pathway. The user-friendliness of this pressure washer was one of Linda’s highlights, with small details going a long way to make using the Stihl RE 120 more enjoyable. She was especially keen on the RA 90 Surface Cleaner attachment from the brand, which sparked her enthusiasm to clean almost every surface in her back garden. Of all the pressure washers she’s tested, Linda also found that connecting and disconnecting this model was easier than the rest.

The one test the STIHL RE 120 Pressure Washer fell down on was cleaning Linda’s dark-coloured car, with some smear marks being left over. This aside, the STIHL RE 120 Pressure Washer proved itself to be an unmissable pressure washer if you’ve got a long list of outdoor jobs to get on with, and a bigger budget.

How to choose the best pressure washer

If you’re buying a new pressure washer for the first time, it can be tricky to know where to start. It all depends on your requirements and the area you’ll be using it on.

When choosing the right pressure washer, think about what you need daily,’ says Henrique Conceicao,area manager, Total Clean. ‘Check the pressure (PSI) and flow (litres per minute), and don’t overshoot your actual need. And remember, whilst power is crucial, comfort in handling is equally vital.’

So, what should you watch out for?

Water pressure and flow rate

‘Look out for a pressure washer that provides both good pressure and a high water flow rate,’ says Paul Hicks, pressure washer expert and Marketing and Product Manager at STIHL GB. ‘It’s easy to get high pressure (like when you put your finger over the end of a hosepipe) but pressure and water flow together give the best cleaning effect.’

Bjørn Snelders, sales manager, consumer UK & Ireland for Nilfisk adds, ‘The flow rate (how much water the machine can actually pass through) is also a key consideration. The combination of both the flow and pressure will determine the overall cleaning effectiveness.’

Don’t go too heavy on the pressure, though. ‘Pressure control is key,’ says Clair Albone, Wickes’ gardening expert. ‘Too much pressure damages delicate surfaces; too little and you won’t clean effectively.’

Pressure washer attachments

Accessories are important to consider, too. You should shop for a pressure washer with attachments that can handle the jobs you need it for.

‘Always check that the right nozzle is being used for the job,’ advises Paul from STIHL. ‘For instance, rotary jet nozzles are not recommended for wooden surfaces, as directing high-pressure water jets directly at the surface could cause damage.’

Storage space

You’ll need to consider where you can store your pressure washer, so make sure you have room available for the model you choose. Compact models are also likely to be a bit cheaper if your budget isn’t massive.

FAQs

What PSI is best for a pressure washer?

The pressure of a pressure washer is measured in PSI, and generally, the higher the bar, the more pressure and power the machine has. But that doesn’t necessarily mean it’s the best option for your space.

‘For light cleaning tasks, such as washing garden furniture, sprucing up your deck or fence, a 100 bar machine with a flow rate of 400 l/per hour would be sufficient,’ says Bjørn from Nilfisk.

‘For medium pressure tasks, look for a 110 to 140 bar pressure with flow rates over 400 l/per hour. This would be ideal for cleaning your car or patio. For heavier and large-area cleaning, a machine of 150 bar or above and a flow rate of over 450 l/per hour is your best bet.’

Handily, there are a number of machines on the market that allow you to adjust the pressure level

What is the average life of a pressure washer?

So, how long does the average pressure washer last?

‘The average life of a pressure washer can vary drastically depending on the frequency and type of use it is subjected to, and on the machine’s pump and motor,’ says Bjørn from Nilfisk. ‘To maximise lifetime, avoid machines with pumps made with less durable materials such as plastic and instead, look for machines which use metal pumps.

‘Another important aspect to consider is the motor. Brushed motors are lighter and intended for less frequent use. They are not recommended for longer or more frequent use. Machines with a brushless/induction motor are heavier but designed for longer periods of use and are also quieter in operation, which your neighbours will appreciate.’
