Karcher HDS 7/10-4 M Professional Hot Water Pressure Washer with Steam Stage 100 Bar

The Kärcher HDS 7/10-4 M is a professional single-phase hot water pressure washer designed for demanding commercial cleaning applications. Operating at up to 100 bar with adjustable pressure from 30 to 100 bar, this middle-class machine delivers exceptional cleaning performance for contractors and facilities requiring reliable hot water cleaning capability. The unit combines a robust 3-piston axial pump with ceramic pistons, a water-cooled 4-pole electric motor, and optimised burner technology to provide efficient and dependable operation.

Built for intensive professional use, the HDS 7/10-4 M features an economical eco!efficiency mode that reduces heating oil consumption to 3.8 kg/h whilst maintaining effective cleaning performance. The machine can heat water to temperatures between 80°C and 155°C (from a 12°C supply), making it ideal for removing grease, oil, and stubborn contaminants in workshops, garages, industrial facilities, and agricultural environments. Two integrated detergent tanks with a precise dosing unit allow quick switching between cleaning solutions, whilst the rinse function ensures thorough system maintenance.

Ergonomics and user comfort have been prioritised throughout the design. The EASY!Force Advanced trigger gun with servo control significantly reduces operator fatigue during extended cleaning sessions, whilst the 1050mm stainless steel spray lance with patented nozzle technology provides excellent reach and control. A comprehensive mobility system features large rubber wheels, a steering roller, and integrated tipping trough for effortless transport across job sites and over obstacles.

Safety and reliability are ensured through multiple protection systems including an accessible water filter to protect the pump from debris, safety valves, water shortage protection, and fuel protection. The Soft Damping System (SDS) compensates for vibration and pressure peaks, extending component life. Intuitive single-switch operation controls all main functions, whilst generous on-board storage includes hooks for the suction hose and power cable, plus a spacious compartment for detergents and cleaning accessories.

Please Note some of the images show the machine with an optional hose reel fitted: this is not supplied as standard with this model but is available separately.
