About this product
The Karcher KHB 4-18 Plus is a battery powered pressure washer that works independently of mains water and electricity, making it useful for cleaning in more remote spots. It runs at medium pressure, with a maximum of 21 bar and a flow rate of up to 170 litres per hour, suiting tasks from cleaning garden furniture, tools and bins to watering plants.
It forms part of the Karcher 18V Battery Power cordless system, so batteries are shared with other tools in the range. The set includes a 5-in-1 Multi Jet nozzle, lance, suction hose (allowing use with unpressurised water sources), a 3/4in garden hose adaptor, an 18V 2.5Ah battery and charger. Maximum water feed temperature is 40°C, and the machine weighs 1.3kg.
