Kärcher high-pressure washer HD 9/20-4 S

The HD 9/20-4 S cold water high-pressure washer is ideal for daily use in demanding conditions. The best materials ensure top quality. Inside the machine is a durable stainless steel piston pump with a brass cylinder head, complemented by a 4-pole motor with an air-water cooling system. Integrated aluminum frame carriers reduce weight and ensure a light yet robust frame suitable for loading with a crane. For a compact design and maximum mobility, the motor and pump are mounted vertically upright. Additionally, the machine has storage compartments. The HD 9/20-4 S takes ergonomic working to the next level. Thanks to the EASY!Force Advanced high-pressure gun, it can be used effortlessly without holding force. The high-pressure gun also features a well-rotating 1050 mm stainless steel lance. The Servo Control located between the gun and the lance can be used to regulate pressure and water volume.
