Powerful and portable: the WD 4-18 S Dual Battery wet and dry vacuum cleaner's 36-volt motor is powered by two 18-volt batteries for powerful suction and maximum freedom of movement while vacuuming. Part of the 18-volt Kärcher Battery Power platform, this battery-powered wet and dry vacuum cleaner removes wet, fine or coarse dirt in no time. The hoover features a robust 20-litre stainless steel container, a 2.2-metre suction hose, a Clips floor nozzle, a fleece filter bag and a handy 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 coming into contact with dirt. Where vacuuming is not possible, the blower function comes in handy. The suction hose storage is space-saving; you can easily 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.
