Clean your garden fast and energy-efficiently with a Kärcher eco!Booster nozzle for your high-pressure cleaner. The eco!Booster is available for the Kärcher K4, K5, and K7 high-pressure cleaners. The lance removes dirt better than a flat jet nozzle, without consuming extra water. That way, you save water and energy. You can also effortlessly clean soft surfaces, because the lance divides the water evenly. This means you can clean surfaces like wood, sand in between your tiles, and painted surfaces.
