Pressure Washers Price Comparison 2026
Compare 166 pressure washers from Kärcher, Bosch and Nilfisk. Find the best price across top UK retailers, from compact electrics to petrol powerhouses.
Pressure washers are one of those purchases where the gap between a cheap impulse buy and the right tool is enormous — and our data makes that gap very visible. With 166 models tracked across dozens of UK retailers, prices stretch from 22 £ for basic units up to 636 £ for professional-grade petrol machines. The sweet spot for most households sits around the median of 139 £, which is precisely where Kärcher dominates with half its catalogue clustered.
Kärcher is the undisputed market leader here — 80 of the products we track carry that yellow livery, at an average price of around 188 £. That dominance is earned: their K-series machines are consistently well-reviewed by Which? and TechRadar alike, and spare parts are widely available from Currys to Amazon.co.uk. That said, Nilfisk and Bosch offer genuinely compelling alternatives, particularly if you want something a touch more compact or you're after a patio cleaner rather than a full-pressure setup. Bosch's average sits notably higher than Nilfisk's, reflecting their focus on mid-to-premium electric models.
The power source question is the first decision to make. Corded electric machines — the vast majority of what's listed here — are the sensible default for garden patios, driveways and car washing. They're quieter, cheaper to run, and perfectly adequate for 80% of domestic jobs. Petrol models like the Draper Tools range are a different beast entirely: louder, heavier, but genuinely useful when you're working far from a mains socket or tackling a large agricultural site. Battery-powered options — Flymo's EasiClean being the standout example — are growing in popularity, especially among those who already own a compatible lithium-ion platform.
One thing worth flagging: several products in this category are listed at very low prices but deliver flow rates below 200 l/h and pressures under 80 bar — barely enough to shift stubborn algae from a patio. If you're comparing prices, don't just look at the headline figure. Check the bar rating and flow rate alongside the cost. A machine priced at 89 £ might clean your car adequately but struggle with a moss-covered driveway. For serious outdoor cleaning, budget at least to the 139 £ mark.

Top products
- Kärcher K 3 Classic Pressure Washer (Kärcher) : The best all-round domestic pressure washer for most UK buyers. Hits the right balance of pressure, flow rate and price — our top recommendation for patios, driveways and car washing alike.
- Kärcher K 2 Compact pressure washer Electric 360 l/h Black, Yellow (Kärcher) : Excellent if storage space is tight — genuinely compact and light enough to carry with one hand. Pressure is adequate for car washing and light patio work, but don't expect miracles on heavily soiled concrete.
- Black & Decker BEPW1300L-GB pressure washer Upright Electric 396 l/h 1300 W Orange (Black & Decker) : The best value alternative to Kärcher at this price point. A solid 396 l/h flow rate punches above its weight, and the upright design stores neatly. Not as refined as the K3, but the price gap is hard to ignore.
- Flymo EasiClean Plus Li pressure washer Compact Battery 200 l/h Black, Orange (Flymo) : The standout battery-powered option — genuinely useful for bikes, garden furniture and car rinsing where a cable would be inconvenient. Flow rate limits it to lighter tasks; don't buy this expecting to replace a corded machine.
- Draper Tools 83818 pressure washer Upright Petrol 474 l/h Black, Blue (Draper Tools) : A serious machine for serious jobs — 474 l/h from a 6.5HP petrol engine means it'll tackle anything a domestic user could throw at it. Loud, heavy and expensive to run, so only buy this if you genuinely need petrol-level performance.

Frequently Asked Questions
What bar pressure do I need for cleaning a patio or driveway?
For a typical concrete or block-paved driveway, you need at least 120 bar — ideally 130–150 bar for anything with embedded moss or oil stains. Most mid-range Kärcher K3 and K4 machines hit this comfortably. Below 100 bar, you'll shift loose dirt but struggle with anything that's had time to settle in. A rotary turbo nozzle can compensate somewhat for lower pressure, but it's not a substitute for adequate bar rating.
Is a Kärcher really worth the premium over cheaper brands?
For most buyers, yes — but not because of raw performance. Kärcher's advantage is longevity, spare parts availability, and after-sales support. A Kärcher K3 bought from Currys or John Lewis comes with a two-year warranty and replacement parts are easy to source years later. Budget alternatives from lesser-known brands can match the headline specs on paper but often use lower-quality pumps that degrade faster. If you're buying a pressure washer you intend to use for five-plus years, the Kärcher premium is justified. For occasional use, a Nilfisk or Black & Decker offers solid value at a lower price point.
Can I use a pressure washer to clean my car safely?
Yes, but keep the pressure below 130 bar and use a wide-angle nozzle (40° or a dedicated car wash nozzle) — never a 0° lance directly on paintwork. Keep the nozzle at least 30 cm from the surface. The Kärcher K2 and K3 models are popular for car washing precisely because their pressure range is appropriate. Avoid turbo nozzles on painted surfaces. If your machine has a detergent injection system, use a pH-neutral car shampoo rather than general-purpose cleaner.
Are battery-powered pressure washers any good, or are they a gimmick?
They're genuinely useful for specific jobs, but they're not a replacement for a corded electric machine. Battery models like the Flymo EasiClean Plus Li typically deliver 200 l/h and around 20–35 bar — enough for rinsing garden furniture, bikes, or a lightly soiled car, but not for a mossy patio or a heavily soiled driveway. The cordless convenience is real, particularly if you're cleaning in areas without easy socket access. If you already own a compatible 18V or 20V battery platform (Bosch, Makita, etc.), a battery washer makes excellent sense as a secondary tool.
What's the difference between the Kärcher K2, K3 and K4 — is it worth going up a level?
Each step up in Kärcher's K-series brings meaningfully higher pressure and flow rate, not just minor tweaks. The K2 (around 110 bar, 360 l/h) handles light domestic tasks. The K3 (130 bar, 380–400 l/h) adds enough power for patios and driveways. The K4 (130 bar but higher flow, better pump) is the step up for regular heavy use or larger areas. The jump from K2 to K3 is worth it for most buyers; K4 and above is only necessary if you're cleaning frequently or tackling large surfaces. Compare current prices across retailers on MagicPrices before deciding — the gap between models fluctuates significantly during Black Friday and January sales.
Should I avoid petrol pressure washers for home use?
For most UK homeowners, yes — petrol machines are overkill and come with real drawbacks. They're loud (often 90+ dB, which will upset neighbours in a typical semi-detached), require fuel storage, need annual servicing, and are significantly heavier. The Draper Tools petrol models in our catalogue are excellent machines, but they're designed for tradespeople and those with large rural properties. Unless you're regularly cleaning large areas without mains electricity access, a quality corded electric machine will do everything you need at a fraction of the running cost.
How do I avoid buying a pressure washer that underperforms its advertised specs?
Check both bar pressure and flow rate together — a machine that claims 160 bar but only delivers 200 l/h will clean slowly despite the impressive pressure figure. Look for independent reviews from Which? or TechRadar rather than relying solely on manufacturer claims. Also check whether the advertised pressure is the maximum (peak) or working pressure — the working pressure is what you'll actually experience in use, and it's typically 20–30% lower. Finally, verify the hose length and what's included in the box; some machines are priced attractively but require you to buy a patio cleaner or extension hose separately.
