The DS 6 Premium is a vacuum cleaner with a water filter and is not only for thoroughly vacuumed floors, but also incidentally also provides for a fresher and 99.95% of dust cleaned exhaust air. This leads to a noticeably more pleasant room climate. Unlike a traditional vacuum cleaner with filter bag, the DS 6 Premium 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 must pass through this water vortex and is thus highly efficiently filtered out of the air and bound in the water. The result is fresh, exceptionally clean exhaust air.
