6.1 Filter Cleaning and Replacement

Do not wash the HEPA filter with water unless specifically instructed by the manufacturer, as this can damage the filter media. Replace the HEPA filter periodically or when suction significantly decreases despite cleaning.
• Foam Filter (if applicable for wet use): Rinse the foam filter with water and allow it to air dry completely before reinstallation.

6.2 Tank Cleaning

After wet vacuuming, always empty and rinse the tank thoroughly with water to prevent mold, mildew, and odors. For dry debris, simply empty the tank into a waste receptacle.

Inspect the hose and accessories regularly for blockages, cracks, or damage. Clear any blockages. Clean accessories with water and mild detergent if necessary, and allow them to dry completely before storage.
