Possible Causes

Worn suction motor bearings, damaged motor fan blades, loose motor mounting, internal debris in motor housing

How to Fix / Troubleshooting

Safety first: Remove the battery before opening the main body. Do not run the motor with covers removed for extended periods.

  • Rule out simple causes: Ensure filters are correctly seated and the dust bin is properly installed; misalignment can increase noise.
  • Access motor compartment: Remove the necessary screws to open the main body (refer to SEBO service documentation). Locate the suction motor.
  • Check motor play: Gently move the motor shaft or fan (if accessible). Excessive side-to-side play or scraping sounds indicate bearing wear.
  • Inspect fan (if visible): Look for broken or chipped fan blades. A damaged fan will cause imbalance and loud noise.
  • Replace motor: Suction motors are not typically serviceable. Replace the entire motor assembly if bearings or fan are damaged.
