Step 1: Check and Clean the Filters

  1. Remove the pre-filters from the vacuum according to the user manual.
  2. Rinse the filters under cold water until clear, then gently squeeze out excess water.
  3. Allow the filters to air dry completely for at least 24 hours before reinstalling.
  4. Replace the filters if they are damaged or excessively worn.

Step 2: Inspect for Blockages

  • Check the wand, cleaner head, and hose for visible debris or obstructions.
  • Remove any debris carefully, ensuring no damage to the components.
  • Use a long, flexible brush or the crevice tool to clear hard-to-reach areas.

Step 3: Verify All Seals and Connections

Ensure that all attachment points, seals, and the dustbin are securely fitted. Loose connections can cause suction leaks, reducing cleaning power. Reattach any loose parts firmly.

Step 4: Check the Battery and Power Settings

  • Make sure the battery is fully charged.
  • Adjust the power mode if necessary; higher power mode may improve suction if debris is heavy.
  • Reset the vacuum if it has a power cycle function.

Additional Tips & Safety Warnings

  • Always unplug or turn off the vacuum before inspecting internal parts or cleaning filters.
  • Do not use harsh chemicals or abrasive materials on filters or plastic parts.
  • If problems persist after troubleshooting, contact Dyson customer support.
