Dyson Inadequate Brush Penetration / Height Setting Issue

Carpet cleaner performance is weak on high-pile or shag carpets

Possible Causes

Incorrect height setting, Worn brush bar bristles, Blocked airflow vents, Low motor power due to clogged filters

How to Fix / Troubleshooting

Safety first: Unplug before adjusting or inspecting the floorhead.

  • Adjust height (if available): Set the floorhead to the appropriate height for high‑pile carpets.
  • Check brush bar condition: Replace if bristles are worn short and cannot reach deep into the pile.
  • Clean vents and filters: Ensure all vents are clear and filters are clean to maximise suction.
  • Use slower passes: Move more slowly over thick carpets to allow the brush and suction to work effectively.
