HDS 10/20-4 M – the most powerful 3-phase hot water high-pressure cleaner in the Kärcher middle class. With 4-pole, water-cooled electric motor, 2 cleaning agent tanks, service electronics.

Feature and Benefits

Efficiency

In the eco!efficiency mode the machine operates in the most economical temperature range (60°C) – with full water flow. The burner cycles are optimised to reduce fuel consumption by 20% compared to full-load operation.

Maximum efficiency

Highly efficient, tried-and-tested burner technology. Four-pole electric motor with three-piston axial pump. Water-cooled motor for a high level of performance and durability.

Operational safety

The large, integrated water fine filter reliably protects the high-pressure pump against small dirt particles. The integrated exhaust gas thermostat switches off the drive motor if the emission temperature exceeds 300 °C. The Soft Damping System (SDS) compensates for vibration and pressure peaks in the high-pressure system.
