Clean or Replace the Filters

Dirty filters are a common cause of loss of suction. Remove the pre-filter and other filters from your vacuum.

Rinse filters with water and let them air dry completely before reinstalling. If filters are damaged or excessively dirty, replace them with compatible replacements such as the 3Pack Pre Filters or V10 Filters.

Empty and Clean the Bin

  1. Remove the dustbin from your Dyson vacuum.
  2. Empty the contents into the trash.
  3. Wash the bin with water if it’s particularly dirty, then dry completely before reassembling.

Check the Cyclone and Air Path

Clean the cyclone by removing dust and debris that may have accumulated, ensuring smooth airflow.

Use a soft brush or cloth to wipe the cyclone and surrounding air pathways.

Test and Maintain

After completing these steps, turn on your vacuum and test if suction has improved. Repeat cleaning or replace parts as needed.

Regular maintenance, including filter replacement and cleaning, will keep your Dyson performing optimally.
