Kärcher OC 6-18 Premium medium pressure cleaner

Compact and mobile cleaning independent of power supply or water connection - battery medium pressure cleaner OC 6-18 Premium is ideal for quick continuous cleaning on the road or around the house. With a fine flat nozzle , stubborn dirt can be quickly removed from bicycles, camping or garden furniture, toys, etc. The 12-liter water cart with wheels and an extendable telescopic handle also serves as a mobile base for the battery-powered medium pressure cleaner. If a water connection is available, the device can also be operated without a tank. With the separately available suction hose, it is also possible to use water from wells, buckets or natural water bodies. The hand spray gun and spray work attachment can be attached to the tank for transport.

Thanks to the wide range of accessories, the OC 6-18 Premium is even more versatile: for example, the foam jet or the washing brush are available separately. The replaceable battery (not included) can be used in all battery devices of the 18 V Kärcher Battery Power platform.
