No Suction / Weak Suction

How to Fix It

1. Empty the bin.

   Press the bin release button to empty the Dyson bin. For corded models, remove the bin and tap it gently to dislodge compacted dust. A bin more than half full noticeably reduces suction — empty it regularly, not just when completely full. Ensure the bin reattaches with a firm click.

2. Wash the filter.

   On cordless Dyson models, the filter is at the top of the motor body (purple or blue cylinder). Remove it by twisting, rinse under cold water until the water runs clear, then tap to remove excess water. Leave to dry in a warm, well-ventilated area for at least 24 hours — putting a wet filter back causes motor damage. Wash monthly for best performance.

3. Check for a blockage.

   Detach the wand from the main body and look through it — you should see light through the wand if clear. Check the hose, flexible reach hose, and all attachments. Look inside the cleaner head by removing it. Use a broom handle to push out any blockages. A tennis-ball-sized wad of debris in the wand is a very common cause of complete suction loss.

4. Clear hair from the brush bar.

   Lay the Dyson floor tool on its back. On most models, the brush bar is accessible by pressing a coin-turn fastener. Cut and pull out hair and fibres wrapped around the bar. A heavily tangled brush bar cannot spin, which dramatically reduces floor pick-up even if suction is fine.

5. Ensure the bin seal and post-filter are correctly seated.

   After emptying and washing, if the bin is not locked in correctly or the post-motor filter is not firmly seated, air bypasses the filtration and suction drops. Press the bin firmly back onto the body until it clicks. Ensure the HEPA post-filter (at the top or rear of the machine) is properly inserted.
