The HD 9/20-4 S Classic cold water high-pressure cleaner delivers high power and Superclass quality – its ergonomic design makes it the perfect tool for everyday use.
The HD 9/20-4 S cold water high-pressure cleaner is ideal for daily use in tough conditions. The finest materials guarantee the highest quality – and you can rely on both from Kärcher. Inside the machine, a durable wobble pump with stainless steel pistons and a brass cylinder head delivers powerful performance, complemented by a 4-pole low-speed motor with air-water cooling system. Integrated aluminum frame supports reduce weight and provide a lightweight yet durable chassis, suitable for crane loading. For a compact design and maximum portability, the motor and pump unit are mounted vertically in an upright arrangement. In addition, it has accessory storage in the form of a storage compartment and adjustable hooks. The HD 9/20-4 S takes ergonomic working to the next level. Thanks to the EASY!Force Advanced gun, it can be operated without holding force, effectively assisted by a rotating 1050 millimeter stainless steel lance. The Servo Control unit, located between the gun and the lance, can be used to adjust pressure and water flow.
