Features & Benefits
The new ECO mode
In the ECO mode the machine operates in the most economical temperature range (60°C) and at the maximum water flow rate. Compared to full-load operation at 80°C, fuel consumption is reduced by up to 20% by optimizing burner operating cycles.

Service switch
The service switch offers a choice of five settings to suit local water hardness. This allows optimum metered quantities of descaler and corrosion inhibitor to be added. And it prevents the build-up of limescale on the heater coil. Furthermore, operating data (machine service) can be called up at any time.

Easy Press and Servo Control
The Easy Press trigger gun significantly reduces holding and operating effort.
The precise Servo controller allows the user to adjust the water flow rate and operating pressure directly on the trigger gun.

Three-piston axial pump
The new, optimized pump is characterized by particularly high efficiency and a long service life.

Ceramic pistons
The three pistons of the axial pump are made of hard, wear-resistant ceramics. This guarantees an exceptionally long wear life.

Detergent switch
The detergent switch is used to select the exactly metered quantities required from the detergent tanks. In the ‘O’ position (feed off), the system is rinsed clear with fresh water.

4-pole motor
The main features of the 4-pole low-speed motor are its longevity and low noise level.

Control panel
The controls and LED indicators on the new Kärcher medium and super class hot water high-pressure cleaners are clearly laid out and designed for intuitive operation.

Defined lifting points for forklift
The new generation of high-pressure cleaners has defined lifting points for handling with a forklift truck – ideal for loading and unloading.Lashing rings
Defined rope attachment points for safe transportation in a service vehicle.

Sturdy large diameter wheels with rubber tyres and caster guarantee trouble-free manoeuvrability. This is enhanced by the ergonomic handles, which are suitable for pushing or pulling the machine.

Tilting aid
The tilting aid enables the machine to be raised at the front to overcome obstacles such as steps, for example.

Flue gas temperature sensor
The flue gas temperature sensor inside the flue shuts off the machine when the flue gas temperature exceeds 300°C. This ensures greater safety for both the machine and the operator.

The chassis is made of corrosion-free plastic. It has an all-round bump guard and built-in fuel and detergent tanks.

Fine mesh water filter
The fine mesh water filter upstream of the float tank traps suspended matter and protects the high-pressure pump from impurities.

SDS Soft damping system
The SDS soft damping system compensates for pressure surges in the high-pressure system and prolongs the life of all high pressure components (e.g. heater coil).

Low fuel cut-out
The unit shuts down automatically when the tank is empty.

Machine Protector Adaptation
The new machine protector system protects heater coils against the build-up of limescale. The cleaning agents in the machine protector Advance series are formulated to protect and maintain the whole machine. The practical 1-litre bottles are inserted in their integral holders and the high-pressure cleaner immediately identifies the care product being used. New to the range is a care additive for the high-pressure pump which also protects it against black water contamination (rust in heater coil due to very soft water).
