Dock Contact or Wiring Failure
Symptom
Vacuum emits a burning smell (plastic or electrical) during operation.
Overheating Component or Electrical Short
Symptom
Vacuum handle or battery area becomes excessively hot to the touch during normal use.
Battery or Motor Overheating
Symptom
Vacuum leaves dust and debris on the floor even though the brush is spinning.
Poor Pickup / Floor Head Performance Degradation
Symptom
Vacuum makes loud grinding or rattling noise from the motor area.
Motor Bearing or Fan Damage
Symptom
Vacuum produces a high-pitched whistling noise during use.
Air Leak at Seals or Cracks
Symptom
Vacuum randomly switches between power modes without user input.
Mode Button or Control PCB Fault
Symptom
Vacuum runs but suction is weak even with fully charged battery and no error code displayed.
General Suction Loss
Symptom
Vacuum runs for a very short time (1–3 minutes) on a full charge before shutting off.
Severely Reduced Battery Capacity
Symptom
Vacuum shuts off after a few seconds of use with no error code; can be restarted but stops again.
Thermal Cutout or Overcurrent Without Display Code
Symptom
Vacuum smells musty or emits an unpleasant odor during use.
Odor from Contaminated Dust Bin or Filters
Symptom
Vacuum turns on only when the handle is held at a certain angle or when the tube is twisted.
