The DS 6 vacuum cleaner with water filter ensures not only thoroughly clean floors, but also fresher, up to 99.5% dust-free exhaust air. And therefore a much more pleasant indoor climate. In contrast to conventional vacuum cleaners with filter bags, the DS 6 vacuum cleaner with water filter relies on the natural force of water which is whirled around the filter at high speeds. The dirt taken in is guided by the whirlpool, reliably filtered from the air and bound in the water. The result: extraordinarily fresh, clean exhaust air.
