Best pressure washer brands
Brand name Average test score Reliability rating Customer score Verdict
68% 65% This brand makes a large range of pressure washers that can tackle both small and large areas. The smaller ones lack the power to shift ingrained dirt and are a bit awkward to use because they only have short hoses. The larger machines tend to do a good job of cleaning, leaving only the most entrenched weeds, moss, lichen, dirt and algae behind. But this brand doesn't have any Best Buys at the moment as its washers seem a bit slow. We're not keen on its patio cleaner accessories either as they're are difficult to use. This brand is fairly well regarded by Which? members, though, scoring satisfactorily in our reliability and customer satisfaction surveys. Overall, some models are worth considering.
72% 71% This brand offers a wide range of pressure washers and accessories for different cleaning tasks. They're all easy to use and do a good or excellent job cleaning all surfaces, which is why we recommend four Best Buys from this brand. Owners are most satisfied with the pressure washers that they own made by this brand. It's a reliable brand, too.
77% 70% This brand is definitely worth your consideration as we currently recommend 10 of its models as Best Buy. Its higher-powered models tend to excel in our tests, removing all the lichen, algae and dirt on our surfaces with alacrity. They tend to be quite heavy machines and can be tricky to manoeuvre, so it's worth checking our reviews to make sure you get a model that's manageable. Owners rate the value for money of this brand's pressure washers higher than other brands, and they have good brand reliability, too.

Choosing the best brand of pressure washer

If you want to buy a pressure washer that can make cleaning your car or patio quick and easy, and leave your paths looking as good as new, then you’ll probably be looking for a Best Buy pressure washer

A great pressure washer can lift road grime from alloy wheels and will remove weeds and moss from between paving stones without causing any damage. It should be a model you can rely on and ideally one you'd be happy to recommend to a friend.

Our brand overview takes all of this into account – including our rigorous test results as well as feedback from hundreds of Which? members who own pressure washers.

 

Customer scores are based on how satisfied Which? members were with a product, and how likely they are to recommend it to a friend.

We test pressure washers from big brands such as Bosch and Karcher, as well as models from less well-known brands, such as Mac Allister and Qualcast, to separate those which give a great all-round clean with minimal effort from the pressure washers that struggle to clean effectively and make you work hard into the bargain.

How we calculate the best and worst brands

We also ask hundreds of Which? members who own pressure washers to tell us how happy they are with the brand they own, enabling us to give a Which? customer score. 

The most popular brand of pressure washers gets a customer score of 71%, and the worst 65%. We also ask about any problems they have experienced with it so we can calculate its reliability rating.
