High-pressure cleaner HDS 9/20-4 MXA

Ergonomic, easy to operate: hot water high-pressure cleaner with automatic hose reel, Eco!Mode and 4-pole, water-cooled electric motor.

Thanks to the automatic hose reel with integrated, 20-metre-long, Teflon-coated Ultra Guard HP hose, the HDS 9/20-4 MXA hot water high-pressure cleaner impresses with high user comfort and short set-up times. The hose reel allows the hose to be wound and unwound at an angle of up to 45° and also reduces the usual set-up time by over 50 per cent. High-quality components and systems, such as the water-cooled 4-pole electric motor, the robust 3-piston axial pump with ceramic piston, the optimised burner engineering and the Eco!Mode, reliably ensure economical and safe 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 spray lance also enables fatigue-free cleaning applications. Furthermore, the maintenance-friendly machine from the Kärcher middle class stands out from the crowd with its 2 detergent tanks, extensive safety technology, patented nozzle technology, high mobility, intuitive operation, time-saving EASY!Lock quick-release fasteners and sophisticated storage options for accessories.
