Step 1: Turn Off and Unplug
Before troubleshooting, ensure the vacuum is turned off and disconnected from any charging source to prevent injury.
Step 2: Check for Blockages
- Remove the cleaner head and inspect for debris or hair wrapped around the brush.
- Detach the wand and check for obstructions inside the tube.
- Look into the dustbin and empty if full.
Step 3: Clean or Replace Filters
Remove the pre-filters and main filters. Rinse filters with water, wring out excess moisture, and let them air dry completely before reinstalling. Replace filters if they are damaged or excessively dirty.
Step 4: Verify Assembly and Connections
Ensure all parts, including the cleaner head, wand, and dustbin, are securely attached. A loose connection can cause suction loss.

Make sure the vacuum is in the correct power mode for your cleaning needs. If the battery is old or not holding charge, consider replacing it or consult Dyson support.
