Clarke has unveiled a hot-water pressure washer capable of blasting away stubborn dirt, but without the weight typically associated with a heated system.

Handily, the 27kg unit runs from a standard 230V plug that powers the 2.3kW motor and can deliver water warmed to 80C.

Called the Harry Hot Wash, the model comes with an 8m-long hose and includes a 300ml detergent bottle. Maximum flow rate is at 450 litres/hour and top pump pressure is 145bar.

Heating the water is powered by a 1-litre onboard diesel tank, although the heater drinks fuel at 1.5l/hour, so regular fill-ups will be needed if you’re always using the hot setting.

It retails on the Machine Mart website for £659.
