No water connection? No problem! With the WT 12-liter water trolley, water is always available where cleaning is needed – whether on the forest parking lot after a mountain biking tour or conveniently without a water connection while cleaning around the house. The water tank, designed as a trolley with large wheels and a telescopic handle, is the perfect complement to the separately available battery-powered medium-pressure cleaner OC 6-18. As a mobile base, the water trolley makes transport comfortable and ergonomic. The water tank can be easily filled at home and transported in the car. Completely leak-proof thanks to a screw cap.
