The HDS 9/20-4 M hot water high-pressure cleaner from Kärcher combines high cleaning quality with high ergonomics and user-friendliness. High-quality components and systems, such as the robust 3-piston axial pump with ceramic piston, the low-speed, water-cooled, 4-pole electric motor, optimised burner engineering and the Eco!Mode, ensure safe and economical operation. When Eco!Mode is activated, the high-pressure cleaner automatically switches to particularly economical 60 °C operation, which is completely sufficient for most cleaning tasks and at the same time reduces fuel consumption by at least 20% compared to maximum hot water operation at 90 °C. The innovative EASY!Force Advanced HP trigger gun with servo control and 1050-millimetre-long stainless steel spray lance with patented nozzle technology is also included as standard for effortless, fatigue-free and ergonomic work. The middle class machine also impresses with its 2 detergent tanks, intuitive 1-switch operation, ergonomic accessory storage, time-saving EASY!Lock quick-release fasteners and a sophisticated mobility concept. Consistently applied safety technology with water filter, safety valves and SDS hose also reliably protects the particularly maintenance-friendly HDS 9/20-4 M from damage.
Highly cost-effective
In Eco!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.
Wide-ranging accessories with EASY!Lock
EASY!Force Advanced for fatigue-free work without any holding force. Pressure and water volume can be adjusted on the Servo Control controller positioned between the lance and trigger gun. Rotating 1050 mm stainless steel lance.
Maximum performance
Burner technology with a minimum output-to-input ratio of 91% – Made in Germany. 4-pole electric motor with 3-piston axial pump. Water-cooled motor for a high performance and long service life.
Operational safety
Easy-to-access water filter protects the pump against dirt particles in the water. Safety valves, water shortage and fuel protection ensure the availability of the machine. The Soft Damping System (SDS) compensates for vibrations and pressure peaks in the high-pressure system.
Multiple storage spaces for accessories integrated into the machine
On-board storage for full range of accessories. Includes 2 hooks for suction hose and power cord. Spacious storage compartment, e.g. for detergents, gloves or tools.
Detergent dosing unit
