The Kärcher HDS 10/21-4 MXA is a premium middle-class hot water pressure washer designed for demanding professional cleaning applications where maximum performance, efficiency, and ease of use are essential. Combining powerful hot water cleaning with Kärcher’s advanced automatic hose reel system, this machine is ideal for industrial cleaning, agriculture, transport, workshops, and heavy commercial use.

Powerful Hot Water Cleaning Performance

With up to 250 bar working pressure and a high water flow rate of 16l/min, the HDS 10/21-4 MXA delivers exceptional cleaning power for removing oil, grease, mud, and stubborn contamination from machinery, vehicles, production areas, and industrial surfaces. The hot water system significantly increases cleaning efficiency while helping reduce detergent usage.

Integrated Automatic Hose Reel (XA System)

The standout feature of the MXA model is its integrated automatic hose reel, allowing fast and convenient winding and unwinding of the high-pressure hose directly at the machine. This improves workflow efficiency, reduces setup time, and helps protect the hose from twisting and damage during daily use.

Durable 4-Pole Water-Cooled Motor

The machine is equipped with a robust slow-running 4-pole water-cooled electric motor and a durable 3-piston axial pump with ceramic pistons, ensuring excellent reliability, low wear, and long service life under continuous professional operation.

eco!efficiency Mode for Reduced Running Costs

Kärcher’s innovative eco!efficiency mode enables economical operation at an optimised temperature setting of 60°C, reducing fuel consumption and emissions while maintaining strong everyday cleaning performance.

EASY!Force Advanced & EASY!Lock System

The professional EASY!Force Advanced trigger gun reduces operator fatigue during extended cleaning tasks by using recoil force to assist trigger operation. Combined with the EASY!Lock quick-connect system, setup and accessory changes are significantly faster and more convenient than traditional threaded fittings.

Built for Professional Reliability

Integrated protection and maintenance systems help maximise machine lifespan and minimise downtime, including:

• SDS vibration damping system
• Integrated water softening system
• Large water filter
• Efficient burner technology
• Pressure cut-off system
• Twin detergent tanks for flexible chemical application

Excellent Mobility & Ergonomic Design

Large wheels, ergonomic push handles, and the compact chassis design make the HDS 10/21-4 MXA easy to manoeuvre across uneven surfaces and busy work environments. Integrated storage compartments keep accessories organised during transport and operation.
