What to know before buying

Listing details to confirm

The listing is inconsistent about pressure, giving 775PSI in the title, 1740 Pound per Square Inch in details and 120 bar in a feature. Hose length is also listed as both 10 Metres and 16 ft high pressure hose. The listed 1400 W power figure sits alongside a battery-powered claim, and the included 4.0Ah battery is described in feature text rather than a package inventory. Confirm the selected listing's specifications and included kit before purchase.

Who is it for?

A good fit for

Buyers wanting a portable washer for car, patio or outdoor cleaning where cord-free operation is useful.
People who want several spray patterns and adjustable settings rather than one fixed spray.

Less suited to

Buyers who need a confirmed pressure rating, hose length or package inventory before choosing a washer.
Those seeking a mains-powered washer, as the product is listed as battery powered.
