Step 2: Check for Blockages
- Detach the wand and cleaner head from the main body.
- Inspect the wand, hose, and cleaner head for visible debris or obstructions.
- Remove any blockages carefully with your fingers or a long, flexible tool.
Step 3: Clean or Replace Filters
- Remove the pre-filters and main filters as instructed in your user manual.
- Wash the filters with cold water, avoiding detergents, and let them air dry completely—usually 24 hours—before reinstalling.
- If filters are damaged or excessively dirty, replace them with compatible filters such as the 3Pack Pre Filters or V10 Filters.
Step 4: Check the Brush Bar
Remove the cleaner head and inspect the brush bar for hair, string, or debris wrapped around it. Use scissors if necessary to cut away tangled hair. Clean the brush bar thoroughly and ensure it spins freely.
Step 5: Reassemble and Test
Reattach all components securely. Turn on the vacuum and test suction by vacuuming a small area. If suction is still weak, proceed to replace filters or parts as needed.
