Sweeping with double power: two 18-volt batteries power a high-performance 36-volt motor for demanding cleaning tasks. The WD 4-18 dual battery wet and dry vacuum cleaner is part of the 18 V Kärcher Battery Power platform and offers maximum freedom of movement while sweeping. The device ideally combines a 2.2-meter flexible suction hose and a floor nozzle with clips and can remove wet, fine, or coarse dirt in no time. The vacuum cleaner features a 20-liter impact-resistant plastic container, a fleece filter bag, and a flat pleated filter suitable for continuous wet and dry suction without needing to change the filter. Thanks to the patented removal technology, the filter can be removed and cleaned in seconds - without coming into contact with dirt. Where vacuum suction is not possible, the blower function comes to the fore. The storage of the flexible suction hose saves space - simply hang it securely on the device's head. The tubes and floor nozzle also park quickly and easily on the bumper. Other features include the ergonomic carrying handle and the "Pull & Push" locking system for easy opening and closing of the container.
