Pressure washer K 4 WCM Premium Home

The K 4 WCM Premium Home with water-cooled motor is perfect for moderate dirt on patios, garden furniture and vehicles. Incl. hose reel and Home Kit.

The K 4 WCM Premium Home impresses with a powerful water-cooled motor, which is characterised by a long lifetime. The pressure washer with 6-metre-long high-pressure hose was built for occasional use and moderate dirt. Thanks to the Vario Power spray lance (VPS) and dirt blaster, patios, garden furniture and vehicles can be cleaned as required. The water pressure can be precisely adjusted to the specific object to be cleaned simply by turning the VPS. Moreover, the dirt blaster with rotating point jet ensures successful cleaning without compromise even on stubborn dirt. The Home Kit includes the T 5 Surface Cleaner and 1 litre of the Stone and Façade Cleaner 3-in-1. The integrated hose reel makes packing away the high-pressure hose child's play, and all other accessories can be stored on the device itself. A built-in water filter reliably protects the pump against dirt particles.
