The DS 6 is a hoover with water filter that not only cleans floors thoroughly, but also provides fresher air and used air from which up to 99.95% of the dust has been removed. This noticeably improves the air and thus the feel in the room. Unlike conventional hoovers with filter bags, the DS 6 hoover with water filter relies on the natural power of water swirling around the filter at high speed. The dirt sucked in has to pass through this swirling water, filtering it out of the air and trapping it in the water very efficiently. The result is fresh, exceptionally clean exhaust air.
