Uncompromising across the board: maximum pressure, maximum flow rate. The HDS 10/20-4 M hot water high-pressure cleaner is the most powerful machine in the Kärcher middle class. An innovative eco!efficiency mode as well as a precise cleaning agent dosing unit and the optimised burner engineering reduce environmental pollution and also benefit your wallet, whereas the patented nozzle technology, ceramic piston, turbo blower as well as the excellent pump efficiency ensure the best cleaning results. The operability, which is characterised for example by an intuitive dashboard, LED displays, as well as a clever mobility concept that makes handling the machine and its transport extremely easy is also optimal. What's more all service and maintenance work is also simple as all components are easily accessible and operating data can be called up easily at any time.
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.
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.
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.
