Possible Causes

Brushroll loaded unevenly with debris, Bent brushroll shaft, Damaged motor fan blades, Loose motor mounting screws

How to Fix / Troubleshooting

Safety first: Remove the battery pack before inspecting moving parts.

  • Clean brushroll thoroughly: Remove the brushroll and clear all debris, especially from one side, which can cause imbalance.
  • Check brushroll straightness: Roll the brushroll on a flat surface. If it wobbles or appears bent, replace it.
  • Isolate vibration source: Run the vacuum briefly without the nozzle. If vibration persists, the main motor fan may be damaged.
  • Inspect motor mount (advanced): Open the main body and verify that the motor is securely mounted. Tighten any loose screws. If the fan is visibly damaged, replace the motor assembly.
