4. Maintenance

Both the General Purpose Dry Filter and the Wet Application Filter are washable and reusable. Regular cleaning and timely replacement are essential for maintaining your shop vacuum's suction performance and extending its lifespan.

4.1 Cleaning Filters

• General Purpose Dry Filter: Tap off loose debris. For heavier dirt, rinse the pleated paper material under running water. Allow the filter to air dry completely before reinstallation for dry use.
• Wet Application Filter: Rinse the foam material thoroughly with water to remove collected liquids and debris. Squeeze out excess water and allow to air dry, or reinstall while damp for wet applications.

7. Troubleshooting

If your wet/dry vacuum experiences reduced suction or decreased performance, consider the following:

• Clogged Filter: The most common cause of reduced suction is a dirty or clogged filter. Refer to the Maintenance section (4.1) for cleaning instructions.
• Incorrect Filter for Application: Ensure you are using the appropriate filter (dry for dry debris, wet for liquids). Using a dry filter for wet pickup can quickly clog it and damage the vacuum.
• Damaged Filter: Inspect filters for tears, holes, or excessive wear. A damaged filter will not provide adequate filtration and should be replaced.
• Improper Installation: Verify that the filter is securely installed using the Qwik Lock system, and that the power head is properly sealed onto the collection tank.

Regular inspection and maintenance of your filters will prevent most performance issues.
