Dust bin overfilled, Cyclone cone blocked, Flap valve at bin inlet stuck open, Using Turbo mode on very large debris

How to Fix / Troubleshooting

Safety first: Remove the battery before cleaning the bin and cyclone.

  • Step 1 – Empty bin: Always empty the dust bin before it reaches the MAX line.
  • Step 2 – Clean cyclone: Remove and clean the cyclone cone and mesh to restore proper separation.
  • Step 3 – Check inlet flap: Inspect the flap valve at the bin inlet (if present) to ensure it moves freely and closes when suction stops.

If the flap is damaged or missing, replace the dust bin assembly.
