Troubleshooting
If you experience reduced suction or poor filtration, consider the following:
- Check Filter Cleanliness: A dirty or clogged filter is the most common cause of reduced suction. Clean the filter as described in the Maintenance section.
- Ensure Proper Installation: Verify that the filter is correctly seated on the filter cage and the clamp ring is securely fastened. An improperly installed filter can lead to air leaks and reduced performance.
- Inspect for Damage: Check the filter for any tears, holes, or excessive wear. A damaged filter will not provide effective filtration and should be replaced.
- Vacuum Canister Seal: Ensure the vacuum canister lid is properly sealed. Leaks can reduce suction power.
