Kärcher K4 WCM Flex eco!Booster Car & Home — 1800W corded pressure washer, 130 bar, 420 L/hr, includes full Car & Home accessory kit
Corded pressure washer with 1800W water-cooled induction motor and 130 bar max pressure. Designed for occasional to regular outdoor cleaning: patios, driveways, decking, cars, motorbikes and garden furniture. Connects to a standard outdoor tap (min. 0.15 MPa). 5m mains cable with standard 13A plug — no special installation needed. Built-in water filter protects the pump from sediment damage.
What makes the eco!Booster different
The eco!Booster lance delivers 50% greater cleaning performance compared to a standard flat jet (Kärcher internal test), while using less water and energy. The wide-angle spray covers more surface per pass — ideal for delicate surfaces including car paintwork, wooden decking and garden furniture where a concentrated jet could cause damage. For stubborn dirt on driveways, paving and grouting, switch to the Dirtblaster lance for a concentrated rotating jet.
