Four backward-firing jets move the hose smoothly through the pipe to effectively clear the blockage. A continuous marking and marking ring show your progress within the pipe, ensuring you reach the source of the clog. This set is suitable for use with all Karcher K2 - K7 series domestic pressure washers and provides powerful cleaning with high pressure.
