Wet and dry vacuum cleaner WD 4 – 20L
The WD 4 20L is built for high-volume cleaning in larger homes and garages. With 240W suction and a dry-use top filter, it is power tool compatible for mess-free DIY tasks.
The WD 4 20L is designed for substantial home projects where a standard vacuum lacks the capacity and durability required. This larger machine is perfect for renovations, providing 240W of suction power to clear fine dust, heavy debris, and liquid spills. The Patented Filter Box positions the filter at the top of the machine, ensuring it never gets wet during liquid recovery and does not reduce the 20L debris capacity. To ensure you do not have to stop mid-job, the Air-Flush function clears the filter with a pulse of air at the touch of a button. For those undertaking decorating tasks, the machine can be equipped with an optional power tool adaptor to capture sawdust and plaster dust before they spread through your home.
