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

The cold water high-pressure washer HD 9/20-4 S Plus is the ideal machine for ergonomic and tireless work. Kärcher's EASY!Force Advanced high-pressure gun makes it comfortable to use without holding force. The pressure and water volume can be adjusted using the Servo Control controller. The Vibrasoft rotating nozzle reduces the vibration of the spray lance by up to 30%. The HD 9/20-4 S Plus is characterized by carefully selected materials and first-class quality. The durable pump, stainless steel pistons and brass cylinder head work together with the air-water cooling system and the 4-pole motor. Integrated carrying handles made of aluminum form a light but strong frame, which makes loading with a crane easy. The motor and pump unit are installed vertically upright to ensure maximum mobility and compact proportions. The machine also has accessory storage.
