A boon - not only for allergy sufferers. The DS 6 vacuum cleaner with water filter not only ensures thoroughly clean floors, but also fresher, 99.5% dust-free exhaust air. And thus for a noticeably more pleasant room climate. In contrast to a conventional vacuum cleaner with filter bag, the DS 6 vacuum cleaner with water filter relies on the natural power of the water, which is swirled in the filter at high speed. The sucked in dirt is led through the water vortex, reliably filtered out of the air and bound in the water. The result: exceptionally fresh, clean exhaust air.
