The Karcher HD 4/11 C BP battery-powered pressure washer is manufactured in Germany and is Karcher's first cordless pressure washer. Storage for 2 x Karcher batteries: the 7.5AH battery gives you a run time of 30 minutes per battery. All accessories with the machine are Karcher industrial attachments, which include a gun, 84cm lance, an Adjustable nozzle for 0, 25 and 40-degree spray angles, a dirt blaster and a 10m hose. With a two-year warranty on the machine, RapidG is your authorised Karcher repair and service agent. The main questions we get asked are: Are battery pressure washers worth it, and which is the best? RapidG is a re-seller of most brands, and the Karcher HD 4/11 battery pressure washer is the best machine by a fair distance and the first battery pressure washer we would endorse for complete cleaning and not as a particular area machine where power is unavailable.
