Cordless Pressure Washer 21V Review UK 2026
Quick verdict
Score: 7.6/10
Best for: Cleaning patios, driveways, decking, cars and garden furniture quickly
Not for: Delicate surfaces up close, or heavy commercial daily use where a petrol or pro machine suits better
Bottom line: A practical pressure washer (45 bar, cordless/battery) that makes light work of outdoor cleaning around the home.
Overall, this cordless pressure washer for the UK market is built around a 21V battery system and a claimed output of 45 bar (652 PSI). It is designed for regular cleaning tasks where portability matters more than sustained power, making it a good match for cars, floors and garden areas when a 5m hose is enough. Battery runtime can limit longer sessions, and results can vary depending on the surface dirt, so planning usage helps keep expectations realistic.

Pressure and Cleaning Power
How much cleaning power does this cordless unit deliver? The Other is rated at 45 bar (652 PSI), providing solid pressure for removing light to moderate dirt from outdoor surfaces, including cars, floors and garden areas. Cleaning performance depends on how evenly the spray hits the grime, as dirt loosens faster when the nozzle angle stays consistent. The 6-in-1 adjustable nozzle lets users match the spray pattern to the task, using a gentler setting on finishes. For tougher stains, pre-rinsing and some scrubbing are still needed.
Flow Rate and Water Use
Flow rate is what turns the stated pressure into usable cleaning results, because 45 bar (652 PSI) pressure alone does not guarantee how quickly water can move grime away. With a cordless pressure washer, water delivery affects how long stubborn marks can be rinsed before performance drops. The 5 m hose length also matters, since water must travel further, and the pressure at the nozzle can feel different than at the pump. Higher flow generally helps with faster rinsing, whereas lower flow may require more passes and careful nozzle setting adjustments for cars, floors, or garden areas.
Accessories and Attachments
With the Other (45 bar/652 PSI), the main accessories and attachments are intended to suit common outdoor cleaning tasks, but the correct nozzle setting still needs to be selected for the surface being cleaned. A 6-in-1 adjustable nozzle system is included, allowing the spray mode to be changed for different uses, including car rinsing, floor cleaning, and garden use. It can also be used for watering-style applications, as long as the chosen setting is appropriate for the area. The attachments are designed for general upkeep, but results depend on selecting the right nozzle level for more delicate materials.
Hose, Reach and Storage
The cordless pressure washer includes a 5 m hose, helping it reach beyond a single tap point for tasks such as cleaning a driveway or rinsing a car. With the extra length, the washer can be kept closer to the work area while positioning the nozzle at wider angles, for example along a garden edge. For storage, a longer hose is easier to manage when coiled neatly after use rather than left kinked, as kinks can limit flow. Rinsing and drying the hose before packing it away also helps reduce grime build-up.
Corded, Cordless or Petrol
Choosing between corded, cordless, and petrol pressure washers comes down to how the cleaner will be used, since power supply affects both reach and day-to-day handling. A corded model is limited by the extension lead, so it suits driveways or patio areas near a socket. A cordless unit suits quick jobs where moving a lead is inconvenient. Petrol washers deliver strong continuous performance for larger sites, but need fuel handling and are less practical indoors. Each option changes day-to-day convenience more than cleaning capability.
Ease of Use and Build
Cordless pressure washers tend to feel simpler to handle than corded models, because setup usually starts with mounting the hose and attaching the spray wand and nozzle. This 21V cordless pressure washer comes with a 5m hose, so it can reach around patios and driveways without searching for an outlet. The build features a 6-in-1 adjustable nozzle, which allows users to switch spray patterns for tasks such as car rinsing, floor washing and garden work. At 45 bar (652 PSI), it provides noticeable cleaning power, but greater force can also splash, so controlled trigger use matters. Overall, it feels portable, although the battery model limits continuous time.
Who Is This Pressure Washer For?
Who this cordless 21V pressure washer suits depends on what gets cleaned most often, and how far the work area is from a power outlet. It fits people who want quick cleaning around a home where extension cords are awkward, because it is portable and cordless. With a 45 bar (652 PSI) output and a 5m hose, it suits cars, floors, and garden areas for small to medium jobs. It also works well for light watering uses, thanks to the adjustable 6-in-1 nozzle. Buyers needing heavy, constant use, or outdoor reach beyond 5m, may find it limiting.
Where to Buy in the UK
Where can this Other be bought in the UK is a common question, particularly when shoppers want to review stock, delivery options, and return terms before paying. Buyers can check major online marketplaces and home-improvement retailers for a 21V portable pressure washer listed with 45 bar output and a 5m hose, but availability can change by region. Before purchasing, they should confirm the listing includes the 2PCS 3.0Ah batteries and the 6-in-1 adjustable nozzle set, and that the hose length is stated as 5m. They should also compare return windows and delivery costs, as these can vary. In-store options may be limited, and some listings may show key details as not stated.
Frequently Asked Questions
Is the Other worth it?
For blasting clean patios, driveways, decking, fencing, cars and garden furniture, the Other saves hours over a hose and brush, with 45 bar of pressure. Check the current Amazon UK price, as it changes often.
Is the Other safe to use on a car?
Yes, with care - use a wide fan or low-pressure nozzle, keep about 30cm from the paint, and avoid blasting trim, badges and tyres up close. Very high pressure can chip paint, so for cars use a gentler setting rather than the full 45 bar.
Is the Other powerful enough for patios and driveways?
The Other delivers 45 bar, which handles patios, driveways and decking well - a patio cleaner attachment makes flat surfaces much quicker. Heavily ingrained moss may still need a couple of passes.
How much pressure do you actually need?
For home use, more isn't always better. Around 100-150 bar (roughly 1,500-2,200 PSI) handles most patios, cars and furniture; very high figures suit heavy-duty or commercial jobs and can damage softer surfaces. Match the pressure to what you'll clean.
Is the Other corded, cordless or petrol?
The Other is cordless (battery-powered), so it's portable and great for cars, bikes and spots away from a socket, though it has lower pressure and run time than a corded model.
Where can you use and store the Other?
The Other connects to an outdoor tap and a power source, with a 5m hose for reach around the garden or car. Drain it down and store it somewhere frost-free over winter, as freezing can crack the pump.
