Step 2: Check for Blockages
- Remove the wand and cleaner head from the main body.
- Inspect the wand, cleaner head, and hose for any debris or obstructions.
- Clear out any visible blockages carefully to restore airflow.
Step 3: Clean or Replace Filters
Dirty filters can restrict airflow and cause suction loss. Remove the pre-filter and main filter, then rinse them thoroughly with water. Allow them to air dry completely before reinstalling. Replace if worn out.
Step 4: Check for Clogs in Filter Housing
Inspect the filter housing for debris or buildup. Clean out dust and obstruction gently with a soft brush or cloth. Ensure all components are dry before reassembling.
Step 5: Test and Troubleshoot Further
Once reassembled, turn on your vacuum. If suction remains weak, verify battery charge or consider replacing filters with compatible ones like the 3Pack Pre Filters or V10 Filters that help maintain peak performance.
