Powerful and portable: the 36-volt motor of the WD 4-18 S dual battery wet and dry vacuum cleaner is powered by two 18-volt batteries for strong suction and maximum freedom of movement while vacuuming. The battery wet and dry vacuum cleaner is part of the 18 V Kärcher Battery Power platform and removes wet, fine, or coarse dirt in no time. The vacuum cleaner features a robust 20-liter stainless steel container, a 2.2-meter suction hose, a floor nozzle with clips, a fleece filter bag, and a convenient flat pleated filter suitable for uninterrupted wet and dry vacuuming without changing the filter. Thanks to the patented removal technology, the filter can be removed and cleaned in seconds - without coming into contact with dirt. Where vacuuming is not possible, the blower function comes into play. Storing the flexible suction hose saves space - simply hang it securely on the device's head. The pipes 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.
