The K4 Compact Pressure Washer combines power & energy efficiency and is equipped with an innovative water-cooled induction motor for enhanced performance and longer life. In addition the Quick Connect hose system eliminates kinking and reduces set up times making it even easier to use.

Compact dimensions allow for convenient transportation and storage. The aluminium telescopic handle and wheels makes this machine easy to use and ensures excellent mobility.

Ideal for cleaning all around the home, the K4 Compact includes a vario lance, detergent suction hose and dirtblaster lance which provides up to 50% greater cleaning power than a standard high pressure lance.

An impact-resistant recyclable plastic casing and fine mesh water filter prevent dirt particles from damaging the motor and three-piston axial-flow pump, whilst a safety valve prevents pressure overload.

All Karcher K4, K5 & K7 Pressure washers can work using a static or harvested water source such as a water butt. Water can either be drawn using a Karcher suction hose & filter or connected to a water butt tap.
