A pressure washer turns an afternoon of scrubbing a patio, drive or car into a ten-minute job, blasting away moss, grime and brake dust with a jet of high-pressure water — and often using far less water than a running hose. An extensive test pitted the base models of the big names — Bosch, Kärcher, Nilfisk and Scheppach — against real dirt on concrete and wood. These are the best, checked against current UK prices.
What to Look For
Two numbers define a pressure washer, and buyers fixate on the wrong one. Pressure, measured in bar, gets the headlines, but flow rate — the litres of water delivered per hour — does as much of the cleaning, sluicing the loosened dirt away; a machine with huge pressure and only a trickle of water cleans slowly. Build quality matters more than the spec sheet suggests, too: the hose, trigger and reel take real abuse, and cheaper units can feel flimsy where it counts. Then weigh the practicalities — hose length, so you can reach the far side of the car without dragging the unit through a flower bed; on-board storage for the lances and cable; and whether a patio-cleaner attachment is included or extra, since that flat, splash-free head transforms flagstone work. It is worth checking the motor as well: units built around an induction motor tend to run quieter and last longer than the cheaper universal type, though they cost more, and a detergent tank or pick-up hose that draws soap into the jet saves a lot of separate scrubbing on cars and render.
The Winner: Nilfisk Core 140
The Nilfisk Core 140 Power Control took the test outright. It shifted ground-in dirt from both concrete and wood without complaint, and — crucially — it felt the most solidly built of the group, where several rivals felt fragile. Power Control lets you dial the pressure to the job from the handle, so you can drop from stripping a patio to gently rinsing a car without swapping nozzles. At around £293.66 it is the priciest here, but it is the one most likely to still be working hard in five years. Check the price on Amazon
Best Value: Kärcher K3

Kärcher is the name most people reach for, and the K3 Power Control is the sensible mainstream buy. It cleans capably, its in-handle pressure display is genuinely useful, and Kärcher's vast ecosystem of patio cleaners, brushes and lances means you can tailor it to almost any job. The honest caveat from testing is build quality — the K3 felt less robust than the Nilfisk — but at around £139.99, with unrivalled accessory support behind it, it is the value pick for the majority of gardens.

Best Budget: Bosch UniversalAquatak
For the lowest outlay, Bosch's UniversalAquatak covers the basics — enough pressure for cars, bikes, patios and garden furniture — in a compact, easy-to-store body. Like the Kärcher it did not feel as sturdily made as the winner in testing, so treat it gently, but for occasional weekend use at around £123.34 it is a lot of cleaning for the money and a fine first pressure washer.

The test's designated value champion was the Scheppach HCE2200, praised as a robust, affordable all-rounder. Frustratingly it is not stocked on Amazon UK — the closest current Scheppach machines here are the pricier HCE2400 and HCE2600 — so if you specifically want the tested model, look to Scheppach's own retailers rather than settling for a merely similar substitute.
How to Choose
Match the machine to your jobs. For a car, a bike and the occasional patio clean, the budget Bosch or the mainstream Kärcher K3 are plenty, and the Kärcher's accessories make light of flagstones. If you have a big drive, decking and years of use ahead — and want a machine that shrugs off the abuse — the Nilfisk Core 140 is worth the premium for its cleaning power and, above all, its build. Look past the raw bar figure to flow rate and construction, buy a patio-cleaner head if you have paving to tackle, and store the washer indoors over winter so the pump cannot freeze and crack. Be honest about how often it will come out, too: for twice-a-year use a budget model is fine and will not resent being stored away, but on a big property where it earns its keep most weekends, the extra outlay on a robust unit pays for itself in longevity.
Verdict
The Nilfisk Core 140 Power Control is the pressure washer to buy if you want the best clean and the sturdiest build, at around £293.66. The Kärcher K3 is the value all-rounder at around £139.99 with the widest accessory range, and the Bosch UniversalAquatak the budget choice at about £123.34. Ignore the pressure-bar arms race, prioritise flow rate and build quality, and any of these will make short work of a grimy patio.
