Mobile Outdoor Cleaner OC 6-18 Premium

Compact and mobile battery-powered medium-pressure cleaner, ideal for quick intermediate cleaning without the need for a power or water connection. The 18 V exchangeable battery, battery charger and suction hose are sold separately.

Compact and mobile cleaning independently of the power or water connection - the OC 6-18 Premium battery-powered medium-pressure cleaner is ideal for quick intermediate cleaning on the go or around the house. With the gentle flat jet nozzle, stubborn dirt can be quickly removed from bicycles, camping or garden furniture, toys and much more. The 12 litre water trolley with large wheels and extendible 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 a separately available suction hose, water from wells, buckets or natural bodies of water can also be used. The pressure gun and spray lance can be fixed to the tank for transport. The extensive range of accessories makes the OC 6-18 Premium even more versatile: a foam jet or a wash brush are available separately, for example. The exchangeable battery (not included in the scope of supply) can be used in all battery-powered devices in the 18 V Kärcher Battery Power platform. Thanks to innovative Real Time Technology, the battery's LCD display shows the remaining capacity when working, charging and storing.
