WD 4 V-20/5/22 Wet & Dry Vacuum Cleaner with Blower Function - Part Number: 1.628-209.0
The WD 4 V-20/5/22 multi-purpose wet and dry vacuum cleaner (commercial part number 1.628-209.0) is a high-performance, professional-grade compact cleaning machine engineered for wet, dry, coarse, and fine debris across workshops, garages, worksites, and home applications. Driven by an energy-efficient 1,100 W rated power motor delivering an effective 240 W suction output (airflow up to 55 l/s and a maximum vacuum of 240 mbar), it guarantees seamless transition between dry and liquid pick-up without changing the filter. Constructed with a heavy-duty 20-litre impact-resistant plastic container, a 2.2-metre suction hose, a 5-metre power cord, and an adaptable clip-on floor nozzle, it features an exclusive patented flat pleated filter removal technology that allows cassette removal in seconds without any direct contact with dirt. Standard equipment also includes a built-in blower function for clearing inaccessible areas, a removable handle for attaching nozzles directly to the suction hose, the robust Pull & Push container locking system, and integrated storage points for parking the hose, tubes, and accessories on the machine body.
Key Features & Engineering Advantages
- Patented Flat Pleated Filter Technology: Slide-out filter box design permits rapid filter removal and cleaning in seconds with zero contact with grime, remaining suitable for both wet and dry vacuuming without filter replacement.
- High-Efficiency Performance (1,100 W Input / 240 W Suction): Optimized motor dynamics that generate 240 W of real suction power and up to 240 mbar vacuum pressure while drawing only 1,100 W of electrical power.
- Integrated Blower Function: Convenient reverse airflow mode that dislodges leaves, shavings, and dirt from gravel beds, narrow cracks, radiators, and tight recesses where direct vacuuming is impractical.
- Durable 20-Litre Impact-Resistant Container: Rugged plastic drum fitted with quick-release "Pull & Push" latches for fast, effortless, and safe emptying.
- Smart On-Board Accessory & Hose Storage: Space-saving profile with top-head recesses for securing the 2.2 m hose, power cord hooks, and bumper-mounted nozzle clips.
- Removable Handle with Direct Tool Coupling: Quick-release ergonomic handle allows 35 mm nominal accessories to be connected straight to the suction hose for agile cleaning in confined spaces.
- Triple-Layer Fleece Filter Bag: Heavy-duty tear-resistant fleece bag provides superior retention of fine airborne dust particles compared to conventional paper filter bags.

Operating Guidelines & Workshop Maintenance Notes: For fine dust and dry dirt pickup, always install the tear-resistant fleece filter bag in combination with the flat pleated filter to safeguard the suction turbine. When vacuuming liquids, remove the fleece filter bag; the flat pleated filter can remain installed in its cassette without taking damage. When maximum liquid capacity is reached in the 20-litre container, the internal float switch automatically cuts suction: switch off the unit, disconnect the plug, and empty the container using the Pull & Push latches. Clean the flat pleated filter periodically by sliding out the patented cassette and tapping it against a firm surface or rinsing under running water (ensure it is completely dry before reinstalling). After vacuuming dirty water or sticky residues, rinse the container and the 2.2 m hose with clean water to prevent clogs and odors.
