Vacuuming with double the power: two 18-volt batteries power a powerful 36-volt motor for demanding cleaning tasks. Part of the 18 V Kärcher Battery Power platform, the WD 4-18 Dual Battery wet and dry vacuum cleaner offers maximum freedom of movement during vacuuming. It perfectly combines a 2.2-metre-long suction hose and removes wet, fine or coarse dirt in no time. The hoover features an impact-resistant 20-litre plastic container, a fleece filter bag and a flat filter suitable for continuous wet and dry vacuuming without the need to change the filter. Thanks to the patented removal technology, the filter can be removed and cleaned in seconds - without contact with dirt. Where vacuuming is not possible, the blowing function proves its worth. The suction hose storage is space-saving; simply and safely hang the hose from the device head. The tubes and floor nozzle can be quickly and easily parked on the bumper. Other features include the ergonomic carrying handle and the "Pull & Push" locking system for easy opening and closing of the container.
