High pressure washer HDS 9/18-4 M

Powerful three-phase HDS 9/18-4 M hot water high-pressure cleaner with 4-pole, water-cooled electric motor, eco!efficiency mode, two cleaning agent tanks and service electronics.

Because hot water cleans better: the HDS 9/18-4 M is a powerful hot water high-pressure cleaner with water-cooled motor. You benefit from a highly efficient cleaning performance, which is ensured by our patented nozzle technology, ceramic pistons, turbo blower and greater pump efficiency. The unique eco!efficiency mode, optimised burner engineering and other equipment features like the switch for water hardness regulation ensure just the right balance between the required cleaning performance and maximum environmental protection. You can also look forward to outstanding user-friendliness: the control panel is intuitive and ergonomic, just like the accessory storage compartments. Despite its size, the machine is manoeuvrable and easy to transport. And of course, all of the components required for maintenance are easily accessible. Using the service switch, the operating data for fault diagnosis can be conveniently retrieved at any time.

Features and benefits
