5. Begin vacuuming dry debris.
6. When finished, turn the vacuum OFF and unplug it.

6. Maintenance

6.1 Emptying the Collection Tank

• Always unplug the vacuum before emptying.
• For dry debris, unlatch the powerhead and lift it off the tank. Carefully remove the filter and dispose of debris.
• For liquids, use the drain plug at the bottom of the tank for convenient emptying.

6.2 Filter Cleaning and Replacement

• Washable Cartridge Filter: For optimal performance, clean the filter regularly. Remove the filter and gently tap it to dislodge loose dirt. For thorough cleaning, rinse the filter under running water. Allow it to air dry completely before reinstallation. Do not use the vacuum with a wet filter for dry pickup.
• Disposable Dust Bag: Replace the disposable dust bag when it is full or when suction power decreases significantly.
