Step 1: Power Off & Unplug

Before troubleshooting, ensure the vacuum is turned off and unplugged from the charging station or wall outlet. Safety first to prevent electrical hazards or accidental activation.

Step 2: Check for Blockages

  1. Inspect the main wand, cleaner head, and hose for obstructions. Detach the cleaner head and remove any debris or tangled hair.
  2. Remove the dustbin and check for clogs in the inlet or outlet. Clear any debris you find.
  3. Use a flashlight if needed to spot hidden blockages inside tubes or filters.

Step 3: Clean or Replace Filters

Dirty or clogged filters can significantly reduce suction. Remove the pre-filter and main filter, rinse them thoroughly with water, and let them air dry completely before reinstalling. Replace filters if they are damaged or heavily soiled.

Step 4: Empty & Inspect Dustbin

Empty the dustbin and check for cracks or damage. Ensure the dustbin is seated correctly when reassembled. A full or damaged bin can restrict airflow and reduce suction.

Step 5: Check the Brush Head & Motor

Ensure the brush head spins freely and is free of tangled hair or debris. If the brush or motor seems faulty, consult the user manual or contact Dyson support for repair options.

Tips & Warnings

  • Always disconnect from power before cleaning or replacing parts.
  • Do not use harsh chemicals to clean filters; rinse with water only.
  • Regularly check for wear and tear on parts, replacing as needed.
  • If suction issues persist after these steps, contact Dyson customer support.
