New levels of performance, reliability and economy

110v, 240v and 420v hot water & steam pressure cleaners

Our new HDS medium and super class hot water high-pressure cleaners reach new levels of performance, reliability and economy. Extensive research and development combined with our unrivalled design and manufacturing capabilities make the new HDS machines our best pressure washers ever. With innovative new features such as the ECO mode, offering fuel savings of up to 20% without compromising cleaning performance, the new HDS range provides our customers with the toughness, cleaning power, and low running costs they demand.

Environmental protection

Improved efficiency (up to 20% savings) with the new ECO mode, service switch for controlling water hardness, turbo fan, precision detergent metering, optimised burner technology and a high efficiency pump.

User friendliness

Clearly arranged control panel designed for intuitive operation, LED display, two secure spray lance holders, an integral, low-friction hose reel with 20 metre hose (MX model only), and much more.

Cleaning performance

Greater water flow rate and pressure than previous machines. Highly efficient cleaning is guaranteed by patented nozzle technology, ceramic pistons, turbo fan and increased pump efficiency. Accessories are optimised for specific applications and designed to exactly suit customer requirements.

Mobility

High mobility and ease of transportation through front casters, large rear wheels with rubber tyres, ergonomic handles, forklift lifting points, tie-down points and tilting aid.

Reliability

Superb features to further enhance reliability include flue gas monitoring, a corrosion-proof, flexurally stiff, robust chassis, machine protector system, three-piston axial pump with ceramic pistons, heat resistant flue outlet, and much more. Now with three-year warranty on heater coils.

Service friendliness

With an improved chassis layout, all key components can be accessed easily and quickly. The new LED service display ensures maintenance tasks can be diagnosed quickly, and usage hours and
maintenance history can be recalled.

Efficiency and reliability for low running costs

The outstanding design and build quality of KÄRCHER hot water high-pressure cleaners makes them
reliable, long lasting and exceptionally efficient, resulting in low fuel and maintenance costs over a number of years.

The new ECO mode

KÄRCHER is the first manufacturer of high-pressure cleaners to introduce an ECO mode on its new generation of hot water units. In 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 optimising burner operating cycles.

Service switch

The service switch offers a choice of five settings to suit local water hardness. This allows the correct metered quantities of machine protector to be added, also preventing limescale build-up on the heater coil and other components. Furthermore, operating data (machine service) can be called up at any time.

Time-proven burner technology with new turbo fan

KÄRCHER burner technology with new turbo fan design provides even greater economy and reduced emissions, without compromising performance.

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, optimised pump design offers high efficiency and a long service life.

Detergent switch

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

4-pole motor

The new 4-pole motor features improved bearings, providing up to 9% longer life on 240V versions and lower noise.

Power nozzle

The patented KÄRCHER Power nozzle cleans large areas thoroughly with more power and efficiency. Compared to a conventional nozzle, the Power nozzle's sharp-contoured spray jet of large droplets increases impact pressure by up to 40%.
