Step 2: Check for Blockages

  1. Remove the wand and cleaning head from the main body.
  2. Inspect the wand, hose, and cleaner head for debris or blockages.
  3. If you find any obstructions, clear them carefully using a long, thin tool or your fingers.

Step 3: Clean or Replace Filters

Filters can clog over time, reducing suction. Remove the pre-filter and main filter as per your model’s instructions. Rinse them with cold water and let them air dry completely for at least 24 hours before reinstalling. For the V15 Detect™, consider using a 3Pack Pre Filters Replacement if yours are heavily soiled.

Step 4: Check the Brush Bar

Remove the Digital Motorbar cleaner head and inspect the brush bar. Remove any hair, string, or debris wrapped around it. If the brush bar is damaged or worn, consider replacing it for optimal cleaning performance.

Step 5: Reassemble and Test

Reattach all parts securely. Turn on your vacuum and test the suction. If suction is still weak, proceed to check the internal air pathways or consider replacing filters or worn parts.
