The K4 Compact Pressure Washer is the compact version of Kärcher’s mid-range machines and combines power and energy efficiency through its water-cooled induction motor resulting in exceptional performance and a longer life. A compact, lay-flat design allows the machine to be easily stored whilst the wheels and telescopic aluminium handle ensures complete mobility. The on-board storage solution means the trigger gun, hose and accessories can be stowed neatly with the machine so that they are always within reach.

A fine mesh water filter prevents dirt particles from damaging the motor and three-piston axial-flow pump, whilst a safety valve eliminates any possibility of pressure overload. The integrated suction hose allows the addition of Kärcher’s full range of detergents to assist in getting the optimum result in your cleaning task.

All Kärcher K4 Pressure washers can work using a static or harvested water source such as a water butt. Water can either be drawn into the machine through a standard hose connected to a water butt tap or using the suction hose and filter which can be purchased separately. The K4 Compact is designed for various tasks including cleaning cars, bicycles, garden furniture and fences, as well as medium sized areas around the home.
