Step 1: Turn off and unplug the vacuum

Always turn off the vacuum and disconnect it from the charging station before performing any maintenance or troubleshooting to prevent electrical hazards.

Step 2: Clean or replace the filters

  1. Remove the pre-filters from the vacuum according to the user manual.
  2. Rinse the filters thoroughly with water, ensuring all dust and debris are washed away.
  3. Let the filters air dry completely—this may take up to 24 hours.
  4. If filters are damaged or very old, replace them with new ones, such as the 3Pack Pre Filters Replacement.

Step 3: Check for airflow blockages

Inspect the cleaner head, wand, and hose for obstructions. Clear any debris or tangled hair that may restrict airflow, which can cause the motor to work harder and drain the battery faster.

Step 4: Test the battery condition

If cleaning filters and removing blockages doesn’t improve battery life, consider the battery’s age. If the battery is old or showing signs of wear, replacing it may be necessary. Contact Dyson support or a qualified technician for battery replacement options.

Tips and Warnings

  • Always use genuine replacement filters and parts to maintain performance and safety.
  • Do not immerse electrical components in water or allow them to get wet.
  • Handle filters carefully to avoid tearing or damaging them.
  • If your vacuum still has poor battery life after troubleshooting, contact Dyson customer support for further assistance.
