Step-by-Step Fix

Safety & Preparation

Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).

  1. For your safety, always begin by switching off your vacuum cleaner at the mains power socket and then unplugging it completely. This crucial step prevents accidental starting and potential injury whilst you're inspecting the machine.
  2. Carefully turn the vacuum cleaner over to inspect the brush head or roller bar located on the underside of the main cleaning head. Look for any tangled hair, string, or large pieces of debris that might be wrapped around the brushes and use scissors or a seam ripper to carefully cut them away, ensuring the brush can spin freely again.
  3. Detach the main hose from both the vacuum body and the cleaning head, then carefully inspect its full length for any obstructions. Shine a torch through one end to see if light appears at the other, or gently run a broom handle through to dislodge any blockages.
  4. Locate your vacuum cleaner's filter – its position varies by model but is often found near the dust bin or motor compartment – and remove it according to your manual's instructions. If the filter is visibly dirty or clogged with dust, clean it thoroughly by shaking, rinsing (if washable), or replacing it as appropriate before reassembling.
  5. Check the height setting dial or lever on your vacuum's cleaning head; if it's set too low, it can prevent proper suction on thicker carpets. Adjust the setting to a higher position suitable for your floor type, ensuring the brushes are at the correct distance to effectively agitate and pick up dirt.
