The Karcher HD 4/11 C BP is a professional cordless pressure washer. It is the first Karcher Pro washer to run on lithium ion batteries. It takes two 36v packs. That suits mobile users and places with no easy mains supply. This listing is the bare tool, so the batteries and charger are extra.
Pressure reaches 150 bar maximum. Working pressure sits between 70 and 110 bar. Flow runs from 320 to 400 litres per hour. Power input is 1.6 kW. Karcher quotes a runtime of 30 minutes on 7.5Ah batteries. An eco!efficiency mode saves charge on lighter jobs. It can take water at up to 60°C.
A suction hose is in the box. It lets the machine draw from tanks and butts. Use it upright or lay it flat. A retractable carry handle helps with loading. The machine weighs 26.4kg. It measures 380 x 370 x 930mm. Parts are strong. You get a brass cylinder head and Easy!Lock quick release couplings. An automatic pressure relief system protects the pump.
The batteries also fit other Karcher Professional 36v cordless tools. If you already own them you save money. The kit includes an Easy!Force trigger gun, a 10 metre hose and an 840mm spray lance. You also get a triple nozzle and a Dirt Blaster lance. It suits mobile valeters and maintenance crews. Batteries come as extras.
