Step 2: Check for Blockages

  1. Inspect the cleaner head, wand, and hose for debris or obstructions. Remove any visible blockages carefully.
  2. Detach the cleaner head and hose, then look inside for hair, dust, or debris that may be clogging airflow.

Step 3: Clean or Replace Filters

Remove the pre-filters and main filters. Rinse the filters with water and let them air dry completely for at least 24 hours before reinstalling. Dirty filters impair suction power.

Step 4: Empty and Check the Bin

Ensure the dustbin is fully emptied and properly reinstalled. A full bin can restrict airflow, reducing suction. Check for cracks or improper sealing.

Step 5: Examine the Brush Bar

Remove hair, string, or debris tangled around the brush bar. Use scissors or a cleaning tool to clear obstructions carefully, ensuring the brush rotates freely.

Tips and Warnings

  • Always ensure filters are dry before reinstalling to prevent mold growth.
  • Do not use harsh chemicals or abrasive tools on filters or plastic parts.
  • If issues persist after cleaning, contact Dyson support for professional assistance.
