Energy efficiency meets high suction power: The WD 4 is super-absorbent with a power consumption of only 1000 watts. The suction cup in modern optics offers a robust & shock-proof 20-liter plastic container and a flat-pleat filter in a filter cartridge, which can be removed quickly by folding out completely without dirt contact. The filter is suitable for wet and dry suction without filter change. The new suction hose and the innovative clip-on nozzle with 2 rubber & 2 brushstrips form an ideal team and always guarantee excellent cleaning results. The detachable handle allows the attachment of the suction hose directly. The park position for the intake manifold and floor nozzle provides excellent service during interruption of work. In addition, the pull & push closure system, the ergonomic handle as well as the practical cable and accessory storage on the device.
