THE Kärcher 397 M and 497 M are two new mobile high-pressure cleaners.

Their upright design makes them easy to move around in rough terrain or up and down stairs.

All accessories, such as lance, trigger gun and six-metre high-pressure hose, are mounted on the case, where they can be seen at a glance.

These cold-water cleaners offer a high performance range. With an operating pressure of up to 1595 or 1740psi and a water throughput of 6.3 and 6.7 litres a minute they are suitable for use in regular cleaning sessions.

Standard equipment includes a dirt blaster for particularly stubborn dirt and a vario power nozzle. Turning the high-pressure lance to varies the water pressure. In low-pressure mode, cleaning agents can be added through the venturi suction hose.

Pressure is generated by a maintenance-free, three-piston axial pump with a cylinder head made of high-strength, corrosion-resistant polyfibre.

It is protected from dirt particles that might damage the pump by a washable fine filter at the water intake point. A pressure switch switches the motor on or off as the trigger gun is operated, which eases pressure on the pump and cuts power and water costs.
