High Pressure Washer – Hot Water / Oil Heated
Kärcher HDS 10/21-4 M
Model: HDS 10/21-4 M *EU-I | Hot Water High-Pressure Cleaner
The Kärcher HDS 10/21-4 M is one of the most powerful hot water high-pressure cleaners in its class, combining outstanding performance with sophisticated ergonomics and a high level of user-friendliness. A low-speed, 4-pole water-cooled electric motor drives a robust 3-piston axial pump with ceramic pistons for maximum output and long service life. The eco!efficiency mode cuts fuel consumption by 20% while maintaining full water flow at 60 °C. From its EASY!Force Advanced trigger gun and Servo Control to its "Jogger" mobility concept and dual detergent tanks, every detail is engineered for fatigue-free, efficient, and economical operation on the most demanding sites.
