Do I need a special bag for fine dust?

The included fleece bag is suitable for standard job site dust; for extremely fine hazardous materials, always verify your specific local safety regulations.

  • Certified L-Class for job site safety

Setup, Compatibility & Care

To set up the unit, attach the suction hose to the inlet port and select the appropriate nozzle for your task. For dry vacuuming, ensure the fleece filter bag is correctly installed to protect the primary flat-folded filter. For wet vacuuming, remove the bag to allow liquid to be collected in the canister.

To maintain optimal performance, regularly inspect the flat-folded filter for excessive debris. If suction power decreases even after using the SFC button, manually clean the filter. Keep the exterior housing clean using a damp cloth and avoid using harsh chemicals. When finished, wind the hose neatly around the unit to prevent kinks and prolong the hose's lifespan.
