Product information and benefits

The WD 4 20L is designed for substantial home projects where a standard vacuum lacks the durability required. This machine provides 240W of suction power to clear fine dust and heavy debris. The Patented Filter Box positions the filter at the top of the machine, ensuring it never gets wet during liquid recovery. This top-mounted design ensures the entire 20L container capacity is available for debris and liquids. To ensure you do not have to stop mid-job, the Air-Flush function clears the filter with a pulse of air. To maintain peak performance, always use a fleece filter bag for dry debris; explicitly remove the fleece filter bag for all liquid pickup.
