Best Cordless Pressure Washer UK (2026)

A cordless pressure washer is for jobs where dragging a mains lead and a garden hose is more hassle than the dirt. Cars on the drive, bikes after a ride, garden furniture, muddy boots, a campervan pitch. It is not a substitute for a 110 bar plug-in machine on a mossy patio.

This guide covers the battery machines you can buy in the UK right now: Worx, Ryobi, Greenworks, Bosch, Kärcher and Makita. Specs and prices come from manufacturer pages and UK retailers in August 2026. If you click through and buy, we may earn a commission.

Worx Nitro HydroShot WG633E

Best overall

• Buy: Amazon.co.uk (kit around £159) · Worx UK (£170, was £200) · Wilko / Homebase around £199
• Pressure: 56 bar allowable, 38 bar rated high / 25 bar eco
• Flow: 220 L/h max (200 L/h rated high, 160 L/h eco)
• Battery: 20V PowerShare. Kit includes a 4Ah pack and 2A charger
• Water: 6 m suction hose, soda-bottle adaptor, quick-connect. Draws from a bucket, bottle, pond or tap
• Weight: 1.5 kg without battery, 2.2 kg with it
• Runtime: about 12 minutes on high, 22 minutes on eco with the 4Ah battery
• Who it is for: anyone who wants one handheld battery pressure washer for cars, bikes, furniture and light patio work

This is the most useful all-rounder on the UK market. It is a gun, not a trolley. You drop the hose in a bucket (or screw on a bottle), click the 5-in-1 nozzle, and work. The IPX7 battery case is there because you will get the pack wet.

Rated pressure is 38 bar, not 56. The higher figure is the allowable peak. That is still well above a garden hose (roughly 2 to 4 bar) and enough to lift road film from a car or dried mud from a bike. It will not strip moss from a large patio the way a Kärcher K4 does.

The kit is the version to buy unless you already own Worx 20V batteries. Bare tool (WG633E.9) is £130 from Worx UK. A spare 4Ah or 5Ah pack is the upgrade that makes a full car wash less stop-start.

Skip it if you need a built-in tank and wheels, or you already live on Ryobi ONE+ or Makita LXT and do not want a second battery family.

Ryobi RY18PWX41A

Best for cars if you already run ONE+

• Buy: Ryobi UK bare tool £120 (was £160) · kit with 4.0Ah £150
• Pressure: 41 / 22 / 7 bar
• Flow: 160 / 110 / 70 L/h
• Battery: any 18V ONE+ pack. IPX5 battery cover
• Water: 6 m siphon, 2 L bottle adaptor, or a standard garden hose
• Weight: 2 kg without battery
• Runtime: up to 22 minutes on high with a 5.0Ah pack
• Who it is for: car and bike owners who already have Ryobi batteries, or who want three pressure steps and a proper tap hook-up

Ryobi’s 18V HP brushless washer is the grown-up handheld. Three power settings matter on a car: 7 bar for glass and paint you do not want to scuff, 22 bar for general washing, 41 bar for arches and wheels. The 3-in-1 nozzle covers turbo, 15° fan and shower.

Expert Reviews named it Cordless Pressure Washer of the Year in April 2025. That tracks with the spec sheet. It is not the highest bar on this list, but it is the one you can plug into a tap when you are on the drive and still siphon from a bucket when you are not.

Buy the kit if you have no ONE+ batteries. Buy the bare tool if you do. A 5.0Ah pack lasts longer than the 4.0Ah in the starter kit. Do not confuse this with the older RY18PW22A 22 bar model, which is a step down.

Skip it if you have no Ryobi tools and you want the highest pressure in a small gun. That is the Worx.

Greenworks G24PW

Best budget pick

• Buy: Greenworks UK £95 tool-only. Third-party listings from around £80
• Pressure: 24 bar
• Flow: 180 L/h
• Battery: Greenworks 24V (not in the box). A 2Ah pack is £30 from Greenworks
• Water: 6 m siphon hose with filter. No built-in tank
• Weight: 4 kg
• Who it is for: first-time buyers who want a named brand under £100 for the tool, or anyone already on Greenworks 24V

This is a handheld siphon washer with a 5-in-1 nozzle and a detergent bottle. Pressure sits with the Kärcher OC 6-18, not with the Worx or Ryobi. Treat it as a strong hose you can take to a water butt, not as a patio blaster.

The honest cost is tool plus battery plus charger. A 2Ah starter pack is cheap. A 4Ah pack is the one to get if you will wash a car. Greenworks quotes a 3-year guarantee on the tool.

Skip it if you do not already own 24V Greenworks batteries and you can stretch to the Worx kit. The extra money buys more pressure and a battery in the box.

Bosch Fontus Gen II

Best with its own tank

• Buy: Wickes £275 · Machine Mart kit £269 · Howe Tools kit £228 · Bosch DIY lists the kit at £305 and the bare tool at £251
• Pressure: 20 bar (low / medium / turbo)
• Flow: 1.5 to 3.1 L/min (about 90 to 186 L/h)
• Battery: 18V Power For All. Most kits include a 2.5Ah pack and charger
• Water: 15 L onboard tank, or a tap. 4 m hose
• Weight: 7.5 kg without accessories, about 9.8 kg as a complete empty unit. Add 15 kg when the tank is full
• Runtime: up to 60 minutes (Bosch claim, 2.5Ah)
• Who it is for: caravans, allotments, front gardens with no outdoor tap, and anyone who wants to fill once and roll the machine to the work

The Fontus is a trolley, not a gun. Fill the 15 litre tank at the kitchen tap, extend the handle, and you do not need a hose run. That is the whole point. Tank trolleys as a class sit on the cordless pressure washer with tank page. 20 bar is modest. Bosch positions it for bikes, cars, furniture, windows and boots, with a SmartBrush in the box for the bits pressure alone will not shift.

Four spray patterns: pencil, 15° fan, 50° fan, shower. You can also clip it to a mains tap if one is there. The 18V pack is the same Power For All battery used across Bosch DIY (and several other brands in that alliance), so existing 18V Bosch garden tools pay for themselves here.

A full tank is short-lived at the higher flow. Plan on one or two refills for a dirty car. The long runtime claim is about the battery, not the water.

Skip it if you always have a tap and you want more punch. A handheld Worx or Ryobi is lighter and stronger.

Kärcher OC 6-18 Premium

Best Kärcher cordless for bikes, camping and furniture

• Buy: Kärcher UK product page · Kärcher Centre Trafalgar £229 · other UK centres and comparison sites £240 to £300
• Pressure: 24 bar
• Flow: 200 L/h
• Battery: 18V Kärcher Battery Power. The Battery Set (1.328-522.0) includes a 2.5Ah pack and charger
• Water: 12 L trolley tank, or a tap. Optional suction hose sold separately
• Weight: 5.7 kg without accessories
• Runtime: up to 12 minutes on 2.5Ah, 24 minutes on 5.0Ah
• Who it is for: Kärcher 18V owners, and anyone who wants a branded trolley with a tank for bikes, toys and garden furniture

Kärcher does not currently push a widely stocked high-pressure battery K 2 in the UK. The OC 6-18 is the cordless model you can actually buy here. It is a medium-pressure cleaner, not a K 2 or K 4. The 12 litre tank on wheels is the feature: enough, Kärcher says, for three to five dirty bikes on one fill.

Runtime on the included 2.5Ah pack is short. If you already own a 5.0Ah 18V Kärcher battery, use that. Foam jet and wash brush are extras. The suction hose is also extra, which is a poor omission if you wanted bucket-draw as well as the tank.

Do not mix this up with the OC 3 / OC 3 Plus. Those are 5 to 6 bar portable rinsers with a 7 litre jug. Fine for muddy boots and a dog after a walk. They are not pressure washers in the sense this page means.

Skip it if you want 40 bar-plus in a handheld, or you are not already on Kärcher 18V. The Fontus has a bigger tank. The Worx has more pressure for less money.

Makita DHW080ZK

Best premium cordless pressure washer (Makita LXT)

• Buy: Power Tool World £340 · Alan Wadkins Toolstore £339 · Amazon.co.uk from around £381 (third-party, often plus delivery)
• Pressure: 30 to 55 bar working, 80 bar max
• Flow: up to 380 L/h (about 330 L/h on high)
• Battery: two 18V LXT packs (36V system). None in the box. Makita recommends 5.0Ah or 6.0Ah
• Water: storage case doubles as a 50 L tank. Self-priming up to 1 m. 5.5 m high-pressure hose
• Weight: 7.1 to 7.9 kg with batteries (tank empty)
• Runtime: 15 minutes high / 34 minutes low with 2 × 6.0Ah
• Who it is for: trades and homeowners already deep in Makita LXT who want the closest thing to a mains washer without a 13A lead

This is the only pick here that behaves like a small pressure washer rather than a powered hose. Self-prime, variable pressure, a real high-pressure hose, and a 50 litre case you can fill from a tap or a water butt. IPX5 wet-guard if the battery cover is closed.

It is also the expensive one. Body-only from about £340, then two decent LXT batteries and a charger if you do not already own them. That can push a first-time buy well past £500. For that money a mains Kärcher K4 or K5 will clean a driveway faster.

Buy it if the batteries are already on the shelf and you need to wash plant, vans or cars away from a socket. Do not buy it as a casual patio toy.

Skip it if you are starting from zero. The Worx kit does 80% of the household jobs at a third of the outlay.

How to choose a cordless pressure washer

Battery platform first

The washer is often cheaper than the batteries. If you already own 18V Ryobi ONE+, Bosch Power For All, Kärcher 18V or Makita LXT, start there. A “bargain” tool that needs a new charger and two packs is not a bargain.

Capacity matters more than voltage on these pumps. A 4Ah or 5Ah pack is the minimum for a car. A 2Ah pack is a bike-and-boots battery.

Pressure and flow

UK boxes quote bar. A garden hose is about 2 to 4 bar.

• Under 20 bar: rinse and light dirt. OC 3 territory, or the Fontus on a gentle setting.
• 20 to 30 bar: bikes, furniture, a careful car wash. Greenworks, Kärcher OC 6-18, Fontus turbo.
• 40 to 56 bar: the useful household cordless range. Ryobi and Worx. Road film, wheel arches, a small patch of patio.
• 55 bar working / 80 bar peak: Makita. Still below a basic mains K 2 (110 bar), but the closest cordless gets.

Flow (L/h) decides how fast you rinse soap off. 160 to 220 L/h is typical for handhelds. The Makita’s 330 to 380 L/h is why it feels more like a “proper” washer.

A mossy 30 m² patio still wants a mains machine. Cordless runtime and flow run out before the slabs do.

Water source

This is the decision most buying guides skip.

1. Siphon from a bucket or water butt. Worx, Ryobi, Greenworks. Cheapest and most flexible. You refill the bucket. Use clean water. Grit wrecks pumps.
2. Onboard tank. Fontus (15 L) or Kärcher OC 6-18 (12 L). No hose to a tap. Heavy once full. Best for a front garden, a car park or a pitch.
3. Tap connector. Ryobi and the trolley models do this well. Unlimited water, still no 13A lead. Best for a car on the drive.
4. Self-prime plus a big tank. Makita. The 50 L case is enough for a real wash if you pre-fill it.

Self-prime means the pump can lift water from a bucket without a tap pushing it in. Handhelds that “draw from any source” do this with a siphon hose. Check the max suction height (Makita states 1 m).

Weight and how you will use it

A 1.5 to 2.2 kg gun lives in the boot. A 10 kg trolley with 15 litres of water does not. If the job is “rinse the mountain bike at the trailhead”, buy a handheld. If the job is “wash the car on a paved front garden with no outdoor tap”, buy a tank trolley.

What we left out

Parkside (Lidl), Titan (Screwfix) and Ferrex (Aldi) are widely sold and sometimes decent. They are not in this list because there is no stable affiliate path, and stock comes and goes with the promotion calendar.

Generic no-name 21V Amazon guns with two mystery batteries look cheap. Spares and safety marking are a lottery. Stick to a brand that still sells batteries in five years.

Nilfisk’s UK range is mains-only. There is no consumer Nilfisk battery washer to recommend.

FAQ

What is the best cordless pressure washer in the UK right now?

For most households, the Worx Nitro HydroShot WG633E. Highest useful pressure in a light gun, kit price around £159 to £170, and it draws from a bucket. If you already own Ryobi 18V batteries, the RY18PWX41A is the better buy.

Can a battery pressure washer wash a car?

Yes, if you treat it as a wash, not a blast. Use a snow-foam or shampoo, a sponge or mitt, then rinse on a mid setting. Worx and Ryobi have the pressure for film and arches. Fontus and the Kärcher OC 6-18 will rinse a car if you refill the tank. None of them replace a tap-fed mains washer for a weekly family-fleet clean.

How long does a cordless pressure washer run?

Handhelds: roughly 12 to 22 minutes on a 4 to 5Ah pack at the high setting. Trolleys: Bosch claims up to 60 minutes, but the 15 L tank empties sooner than that. Makita: 15 minutes high on two 6.0Ah packs. A second battery is the practical answer, not a bigger pump.

Do I need a tap for a cordless pressure washer?

No. That is the reason to buy one. You do need a water source: a bucket, a water butt, a bottle, or a built-in tank. Tap hook-up is a bonus for driveway work, not a requirement.

Is a cordless pressure washer powerful enough for a patio?

For a small, lightly dirty area, a Worx or Ryobi on a narrow jet will help. For green paving, driveway oil or a full terrace, buy a mains washer in the 130 to 145 bar class. Cordless water volume and battery time are the limit, not just bar.

Are cordless and battery-powered the same thing?

Yes. Shops use both names for the same machines. Check bar, battery platform and how it takes water.
