Best pressure washers 2026: tested on patios, decking and cars

The trouble with the great outdoors is that it gets a bit untidy. Your garden tools might do a good job of keeping your plot in check, but keeping your patio, decking and outdoor furniture spick and span can take hours, especially if you rely on a bucket of soapy water and a scrubbing brush. That's where a pressure washer comes in. These handy tools connect to your hose pipe and squirt water at any cleaning problem. Stubborn and unpleasant stains, from bird dirt to years of neglect, can be lifted from your garden's hard-wearing surfaces in seconds. With the right attachments, you can also use your pressure washer to hose down cars, bikes and boats.

Car & Home Why you should trust me I've been testing all sorts of cleaning gadgets for years. I've tested vacuum cleaners, mops, hard-floor cleaners, carpet cleaners, window vacs and various robots designed to do jobs automatically, from internal cleaning to lawn mowing. I've got a keen nose for a labour-saving device, and I live in a busy household that never seems short of a dirty surface to test things on, including an extensive patio area and a filthy car. There was a perfect alignment of dirty jobs crying out to test these pressure washers on.

How I tested I gathered 11 pressure washers of various types and prices from a range of manufacturers, and put each through the same tests, over two testing periods. First, I used each washer to clean one of the dirty paving slabs at the side of my house. This is where the dog gets washed after walks, and it's a well-trodden thoroughfare, making it a dark and grimy corridor. Next, I wanted to test the washers on decking. Unfortunately, I don't have a deck of my own, so I had to find someone else's to clean. Fortunately, a shoutout on our neighbourhood WhatsApp group found a neighbour with a deck that hadn't had a deep clean for a few years, so it was primed and ready to challenge the washers. This was by far the wettest job of the lot – but my neighbour was delighted with the extreme hose down I gave it. I then washed the wheels of my car. As with most cars, it has only four, so I washed half of each wheel with each washer, so I could compare their work. Where appropriate, I tried the various attachments and settings that I hadn't used previously on other jobs. It included cleaning out empty water butts, clearing a few years of built-up algae off my whirligig and testing the supplied foam cannon on the rest of my car. All the pressure washers were supplied by their manufacturers, most of whom will pick them up when I've finished. Any that don't get collected will be given to Workaid, a Chesham-based charity that refurbishes tools of all kinds. It donates them to training centres and self-help organisations in Africa and the UK, to help young people develop new skills or start their own businesses.

The best pressure washers in 2026 The best of the rest What you need to know What to look out for Hoses Your pressure washer will come with a high-pressure hose to connect the pump unit to the spray gun. If you're going to use your pressure washer a lot, opt for an anti-tangle or premium hose, as these are easier to manage. Lesser hoses don't unwind as well and require regular untwisting as you work. When it comes to connecting the pressure washer to your water supply, you'll need your own hose. Every pressure washer we've tested uses the standard 0.5in quick-connect attachment, compatible with most garden hoses and accessories found in the UK, including the Hozelock system. Solid plastic hoses are generally better here than the softer expandable hoses because they're less liable to kink and restrict the required volume of water getting to the pump. The exception may be if you get a portable pressure washer that can operate from an alternative water supply. This may come with its own short length of hose you can dangle into any available source of water.

Nozzles Pressure washers come with various nozzles. These are usually interchangeable and sit at the end of the spray gun, creating different angles of spray for different levels of pressure and cleaning power. A concentrated narrow spray, for example, produces a lot of water pressure at the tip, which is useful for precision cleaning. A fan that spreads the water across a larger area produces less pressure and is suitable for more delicate surfaces. Some nozzles may be variable, offering options from a single nozzle. The other type of nozzle has a relatively narrow angle but rotates the water around a slightly larger area. These are often called turbo or dirt-blaster nozzles. They have all the power of a concentrated nozzle, but work faster as they work over a greater surface area.

Attachments Most pressure washers have a range of accessories available. Some may come in the box, and others can be bought separately. The most common accessories are reservoirs that add detergent to your washer. These are normally used to produce a covering of suds over something particularly dirty, such as a car. This should work its way into the dirt so you can rinse it with a lighter spray to remove both the soap and the dirt. Other attachments put a brush or mop on the end of the spray gun. This adds a constant supply of clean water to these more traditional cleaning tools. Brushes are good for patios and decking, particularly where the pressure from a jet might damage older surfaces. Mops are good on cars, particularly for wiping down after a dousing of detergent. If you have a particular attachment in mind, look out for bundles that include it, as many washers come in both bare-bones and fully loaded versions. Kits with attachments are more expensive, but are usually better value than buying those attachments separately.

How do you use a pressure washer? Pressure washers are simple tools that accept water from a water supply, build up the pressure using an electric motor, and then squirt out the water again from a gun attached to a separate hose (called a pressure hose). All the washers I tested use a universal garden hose attachment that lets them easily hook up to your water supply. My garden hose has a Hozelock connector, which fitted perfectly on to every model, so check yours is compatible. Once the water is connected and the tap is on, you can power up the washer either by connecting it to the mains or charging and slotting in a battery. Then you simply select an appropriate attachment or setting, depending on the pressure you want, and point it at the dirt. The gun has a trigger so you can start and stop the water as you please without returning to the main unit or closing the tap.

What safety equipment do you need? Keep in mind that dirt and debris can fly around when squirted at high pressure. Safety glasses, long trousers and proper shoes should be worn. Gloves are a good idea, and you might want to deck yourself out in some waterproof clothing.

What is a good pressure for home use? Different jobs require different levels of pressure. Heavy-duty dirty work, such as blasting a concrete paving slab, is best done with high-pressure washers that can produce pressure in excess of 100 bar (1,450PSI). You can get decent results from lower-pressure washers, too, but it might take a bit longer. Softer surfaces, such as wooden fencing and decking, shouldn't be attacked with the highest pressure settings of a powerful washer but can be hosed down with a less powerful spray. Washers with pressure of less than 100 bar can be used for this kind of thing. Try your washer on a small and inconspicuous area first to see how it fares before tackling the whole thing. Some jobs are best done with the pressure at a minimum, such as washing your car. Although you can still use a pressure washer for this, you should use a rinse or fan setting from a safe distance – the pressure is most intense at the tip of the nozzle. Pressure washers with foam cannon are good for covering a car with soap, which you can then rinse after it's lifted off some of the dirt. Don't mix detergent with your pressure washer's main water supply, though, as this can damage the device.

Are pressure washers noisy? None of the pressure washers I've reviewed here was particularly noisy. Your nextdoor neighbour will notice when you're using one, but they're quieter than lawnmowers and hedge trimmers. There's no requirement to wear ear defenders.

Can I rent a power washer instead? You can, and it makes sense if you need a washer for a one-off job or you don't have the space to store one. National hire services such as HSS and B&Q offer pressure washers, which you can order online and have delivered to your home. It's a good option if you're looking for a more powerful washer, as these tend to be more expensive to buy. There may be competitively priced local hire services or even tool share groups in your area, too, so it's worth comparing prices online before you commit.

Should I put detergent in my power washer? Never put detergent through the main water inlet of a pressure washer, as it can cause permanent damage. Some pressure washers come with a separate reservoir for detergent, which is either connected to the main unit or attached to the end of the spray gun. These add detergent to the mix after the water has been pressurised, so they are safe to use. However, it's worth checking the manual for instructions and information on the type of detergent to use.

Can you clean your patio without using a pressure washer? Yes. You can clean a patio with soapy water and a stiff brush, though it might take some scrubbing. You can mix water with white vinegar to remove particularly stubborn stains – be sure to be careful around plants, though. Products such as Wet & Forget are good if applied on a dry day and allowed to dry, as they can stop algae and other dirt from building up in the first place. Keep pets away until the surface is dry.
