2. Clean or Replace the Filters

Dirty filters can cause the vacuum to pulse by restricting airflow. Remove the pre-filters and main filters as per the manual. Rinse washable filters with water and let them air dry completely before reinstalling. If filters are excessively worn or damaged, replace them with suitable replacements.

3. Check the Battery and Charging Port

  1. Ensure the vacuum is fully charged; a low or faulty battery can cause power fluctuations.
  2. Inspect the charging port and cable for damage or debris.
  3. If the battery shows signs of overheating or age, consider replacing it or contacting Dyson support for assistance.

4. Examine the Motor and Electrical Connections

Loose or damaged wiring can cause intermittent power delivery. Carefully check visible wiring and connections inside the vacuum. If you’re uncomfortable with internal inspection, seek professional repair or contact Dyson support.

5. Perform Maintenance and Reset

After cleaning filters and checking connections, reset your vacuum by turning it off, then on again. Regular maintenance, including filter replacement every 2-3 months, helps prevent pulsing issues.
