Key takeaways
- Cordless pressure washers are having a moment this summer because they draw water from a bucket or water butt, so they still work where a hosepipe ban is in force for car and patio washing.
- Most cordless models sit around 20 to 24 bar, which is fine for cars, bikes, patios and garden furniture but well short of a mains-fed washer for heavy driveway grime.
- The WORX HydroShot WG625 is the pick most people should start with at around £130, with the brushless Nitro WG633E for tougher jobs.
- Budget 6-in-1 kits from around £40 to £60 include two batteries and a foam cannon, but build quality and after-sales support are a gamble.
Britain has spent the past few weeks under back-to-back heatwaves, and with parts of the country now facing hosepipe restrictions, a normal mains pressure washer is either banned or a hassle. That is why cordless models are flying off Amazon this summer. They run off a battery and pull water from a bucket, a water butt or a tub of reused washing-up water, so you can still rinse the car, blast the patio or clean the decking without a tap and hose. They are also lighter, quieter and quicker to grab for a five-minute job.
The trade-off is power. A cordless washer will not shift years of ground-in driveway moss the way a corded Karcher will. But for the jobs most people actually do in July, they are more than enough. Here are six worth buying right now, with a clear best-for angle on each.
How we picked these
We looked at pressure (measured in bar), flow rate, and how long each one runs on a charge, since a cordless washer lives or dies on battery life. We gave weight to models that draw from a bucket or water butt rather than needing a pressurised tap, because that is the whole point of going cordless in a dry summer. We also checked whether spare batteries and nozzles are included, how portable the unit is, and what the warranty and brand support look like. Amazon UK ratings and review counts helped separate the models people keep from the ones that get returned. On the water side, the advice from water companies during a hosepipe ban is that you can usually still wash a car or clean surfaces using water from a bucket or a container, which is exactly how these run.

WORX HydroShot WG625
Best overallThe one most people should buy. It draws water from any bucket, tub or water butt, has a 5-in-1 nozzle that twists from a fine jet to a wide fan, and the 20V PowerShare battery works with other WORX tools if you already own them. With more than 1,800 Amazon ratings it is the most proven cordless washer on the UK site, and it is genuinely handy for cars, bikes, muddy boots and garden furniture.
The catch: at up to 22 bar it is a rinser, not a heavy cleaner, and a single battery gives you roughly 15 to 20 minutes before a recharge.

Best for tough patio and deckingThe step up if the standard HydroShot feels weak. The Nitro uses a brushless motor and pushes up to 56 bar with a higher flow rate, so it clears patio grime, decking and mossy paving that the cheaper model just smears around. Same PowerShare battery system, so it fits the wider WORX 20V range.
The catch: it is pricier and thirstier on the battery, so for longer sessions you will want a second cell, which adds to the cost.

Best for brand trustIf you would rather pay more for a name you know and a proper warranty network, the Bosch Fontus is the pick. It has a built-in tank plus the option to feed from a bucket, adjustable pressure settings, and it slots into Bosch’s 18V home and garden battery family. Well built and easy to store.
The catch: it is the most expensive here by some margin, the pressure is still modest, and the on-board tank is small so you top it up often on bigger jobs.

Check price on Amazon6-in-1 Cordless Patio & Car Washer
Best for washing the carA well-priced kit aimed squarely at car and patio use. It ships with a 5-metre hose, a foam cannon for a proper snow-foam wash, and two batteries so one is always charging. The six nozzle modes cover everything from a gentle rinse to a tighter jet for alloys.
The catch: it is an unbranded make, so long-term reliability and spare parts are less certain than with WORX or Bosch. Treat it as a two-to-three season tool.
5m hose, foam cannon, 2 batteries · around £60
Check price on Amazon6-in-1 Cordless Washer with 2 Batteries
Best budget buyMuch the same idea for a little less. Two batteries, a 5-metre hose and six spray modes for around fifty pounds. For occasional patio rinses, bins, bikes and garden furniture it does the job without you thinking twice about the outlay.
The catch: each battery only lasts a short session, and the plastic build feels its price, so it is best kept for light and occasional use.
2 batteries, 5m hose · around £50
Check price on Amazon1200 PSI Portable Cordless Washer
Cheapest for light jobsThe wallet option. It comes with two batteries and claims a peak around 1200 PSI, and for quick jobs like rinsing muddy wellies, cleaning the bins or a light patio wash it is fine. Hard to argue at under forty pounds if your needs are modest.
The catch: flow rate is low, so anything bigger than a light rinse takes patience, and this is the category where cheap units are most likely to fail early.
2 batteries, light-duty · around £37

Can I use a cordless pressure washer during a hosepipe ban?
Usually yes, because the ban is on using a hosepipe connected to the mains, not on cleaning itself. A cordless washer draws from a bucket or water butt, and washing a car or surfaces with water from a container is normally still allowed. Check your own water company’s wording, as the rules vary by region and can change during a drought.
Are cordless pressure washers powerful enough for a driveway?
For a light clean, yes. For heavy, ground-in grime and moss across a big driveway, no. Cordless units top out around 20 to 56 bar, while a mains washer runs well over 100. If your main job is a large driveway, a corded washer is the better buy. For cars, patios, decking, bikes and furniture, cordless is plenty.
How long does the battery last?
Expect roughly 10 to 20 minutes of continuous spraying per battery on most models, less on the higher-pressure settings. That is why kits with two batteries are worth having, so one charges while you use the other.
Do they come with everything I need?
The budget kits usually include batteries, a hose, a foam cannon and several nozzles. The WORX HydroShot is sometimes sold as a bare tool, so check whether the listing includes a battery and charger before you buy, or you may need to add those separately.
