The DS 6 vacuum cleaner with water filter not only thoroughly cleans the floor, but also ensures fresher exhaust air without dust by 99.5%. And a much more pleasant atmosphere indoors. Unlike a conventional vacuum cleaner with a filter bag, the newly designed DS 6 vacuum cleaner with a water filter is based on the natural force of water stirring rapidly inside the filter. The aspirated pollutants pass through the stirred water, are reliably filtered from the air and are trapped by the water. The result: very clean and fresh air coming out.
