The HDS 9/20-4 M hot water high-pressure cleaner from Kärcher combines the highest cleaning quality with the best 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 economical eco!efficiency mode, ensure safe and economical operation. 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.
Maximum Efficiency with eco!efficiency Mode
One of the standout features of this Kärcher model is the innovative eco!efficiency mode. When you operate the machine in this setting, it runs in the most economical temperature range (60°C) while maintaining full water flow. Consequently, this optimizes burner cycles and reduces fuel consumption by up to 20%. Therefore, it is an environmentally friendly and cost-effective choice for your business.
Ergonomic Handling and Advanced Technology
You can now say goodbye to operator fatigue. This specific HDS 9/20-4 M comes standard with the EASY!Force Advanced trigger gun. This revolutionary technology uses the recoil force of the water jet to reduce the holding force to zero.
-
Total Control: Adjust pressure and water volume directly from the handle.
-
Quick Setup: Use the EASY!Lock fasteners to set up five times faster than standard screws.
Superior Performance and Durability
Built to last, this high-pressure cleaner features a water-cooled, 4-pole electric motor. Furthermore, it includes a robust 3-piston axial pump with ceramic pistons. As a result, the hardware ensures a long service life even under heavy daily use.
Key Performance Specs:
-
Working Pressure: 30–200 bar (Adjustable)
-
Flow Rate: 450–900 liters per hour
-
Max Temperature: Up to 155°C (Steam stage)
User-Friendly Design and Mobility
The “jogger” design features large rubber wheels and a front steering roller for better movement. Additionally, the integrated tipping trough allows you to tilt the machine easily. This makes it simple to navigate over ledges and uneven terrain. Moreover, the on-board storage keeps your nozzles and tools organized and within reach.
