Step 2: Clean or Replace Filters

  • Remove the pre-filters and filters as per the user manual.
  • Rinse the filters with water and let them air dry completely before reinstalling.
  • If filters are worn or damaged, replace them with genuine replacements like the 3Pack Pre Filters.

Step 3: Clear Blockages and Debris

  1. Check the wand, cleaner heads, and crevice tools for clogs or trapped debris.
  2. Remove any blockages carefully to restore airflow.
  3. Ensure no hair or debris is wrapping around the brush bars or filters.

Use the LCD screen to monitor power mode and remaining run time. Switch to lower power modes if possible to conserve battery during cleaning sessions. Avoid overusing high-power modes unnecessarily.

Step 5: Replace the Battery (if necessary)

If your vacuum still experiences rapid battery drain after troubleshooting, consider replacing the battery. Consult Dyson customer support or authorized service providers for genuine replacement batteries compatible with your model.
