Product information and benefits

The HD 10/21-4 S Plus cold water high-pressure cleaner is the ideal machine for ergonomic and fatigue-free work. The Kärcher EASY!Force Advanced trigger gun makes it comfortable to use without any holding force. The Servo Control controller regulates the pressure and water volume. The Vibrasoft rotary nozzle reduces vibrations on the spray lance by up to 30%. Carefully selected materials and premium quality are the hallmarks of the HD 10/21-4 S Plus. A hard-wearing wobble pump, stainless steel pistons and brass cylinder head work in partnership with a 4-pole low-speed motor with air-water cooling system.
