Product information and benefits

The HDS 10/21-4 M is one of the most powerful hot water high-pressure cleaners in the middle class and also impresses with its sophisticated ergonomics and high level of user-friendliness. Its low-speed, 4-pole and water-cooled electric motor, the robust 3-piston axial pump with ceramic piston and the Eco!Mode simultaneously ensure high performance and reliable, 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 energy-saving EASY!Force Advanced HP trigger gun with servo control and 1050-millimetre-long spray lance with patented nozzle technology as well as the EASY!Lock quick-release fasteners are also included as standard for fatigue-free and time-saving work. Many other equipment and performance details are also impressive, such as the optimised burner engineering, the 2 detergent tanks, the convenient mobility concept, the extensive safety technology, the simple operation with just one switch or the clever accessory storage options.

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

Easy to switch between detergent tank 1 and 2. Precise detergent dosing unit with rinse function.

Mobility concept

"Jogger" design with large rubber wheels and steering roller. Integrated tipping trough for effortless transport over ledges. Push handles for simple transport and manoeuvrability.
