Top-of-range domestic corded pressure washer with 2800W water-cooled induction motor for frequent, heavy-duty outdoor cleaning. Covers approx. 60 m²/hour — the highest area performance in Kärcher’s domestic K range. Suited to large patios, driveways, decking, exterior walls, garden machinery, large vehicles and commercial vehicles. Accepts hot water inlet up to 60°C (unlike K2–K5 models limited to 40°C). Connects to a standard outdoor tap (min. 0.15 MPa). 5m mains cable with standard 13A plug.
What the eco!Booster lance does
The eco!Booster lance delivers 50% greater cleaning performance compared to a standard flat jet (confirmed by an independent testing institute), while using the same amount of water and energy. The wide-angle spray covers more surface per pass and runs significantly quieter than a standard flat jet — ideal for car paintwork, wooden decking and garden furniture where concentrated pressure could cause surface damage. For the toughest heavy-duty grime on paving, concrete and stubborn moss, switch to the Dirtblaster lance for maximum concentrated rotating jet power.
