Clean or Replace Filters

Dirty filters can cause airflow restrictions, leading to pulsing. Remove the pre-filters and main filters according to your model’s instructions.

  • Rinse the filters under water if washable, and let them air dry completely (at least 24 hours).
  • Replace filters if they are damaged or excessively dirty.
  • Reinstall the filters and run the vacuum to check performance.

Check for Overheating

Overheating can trigger the pulsing to protect the motor. Ensure the vacuum is used correctly and not on overly thick or dense carpets for extended periods.

  • Allow the vacuum to cool down for at least 30 minutes if it feels hot.
  • Avoid blocking airflow vents during use.

Ensure Proper Battery and Power Settings

Make sure the battery is charged and connected properly. Use the appropriate power mode for the task—higher power on carpets, lower on hard floors.

  • Check the LCD screen for alerts or errors.
  • Reset the vacuum if necessary by turning it off, then on again.

Additional Tips and Warnings

  • Always unplug before performing maintenance.
  • Use genuine filters and attachments for best results.
  • Regularly clean the filters and check for blockages to avoid pulsing issues.
  • If problems persist after troubleshooting, contact Dyson support or a qualified technician.
