Firmware Corruption / MCU Boot Error
Symptom
Charging LED on the vacuum or charger never turns green/full, charging seems to continue indefinitely.
Charge Termination / Battery Detection Fault
Symptom
Cordless vacuum has very weak suction even with fully charged battery.
Airflow Restriction / General Loss of Suction
Symptom
Dust escapes from joints and seams, visible dust on the outside of the vacuum after use.
Air Leak / Seal Failure
Symptom
Fine dust blowing out of exhaust, air feels dusty despite HEPA filter installed.
Exhaust Filtration Failure
Symptom
LED battery indicator does not light at all, even though the vacuum runs.
Battery Indicator Display Failure
Symptom
Motorized floor brush does not spin, but suction is normal.
Brush Roll Drive Failure
Symptom
Power button must be held continuously for the vacuum to run, instead of toggling on/off as before.
Control Logic / Latching Fault
Symptom
Strong burning smell from the vacuum during use.
Overheating Motor or Electrical Component
Symptom
Vacuum cannot be docked or charged properly in the wall mount or floor stand.
Charging Cradle Alignment / Contact Issue
Symptom
Vacuum cannot stand properly in the charging stand or wall mount; it wobbles or falls.
Mechanical Mounting / Docking Instability
Symptom
Vacuum emits a high‑frequency electronic squeal or whine from the handle area.
Switching Power Electronics Noise
Symptom
Vacuum handle or battery area becomes unusually hot during normal use.
Battery or Electronics Overheating
Symptom
Vacuum intermittently turns off when the tube is moved or rotated.
Intermittent Electrical Connection in Tube or Nozzle
Symptom
Vacuum leaves lines of debris and does not pick up well from carpets.
Brush Roll Performance Issue
Symptom
Vacuum makes a rattling noise from inside the dust container area.
Loose Cyclone or Internal Bin Components
Symptom
Vacuum motor makes a loud high‑pitched whine or grinding noise during operation.
Motor Bearing Wear / Fan Damage
Symptom
Vacuum produces excessive vibration and rattling during use.
Mechanical Imbalance / Loose Components
Symptom
Vacuum runs for only a few minutes on a full charge before shutting off.
Battery Capacity Degradation
Symptom
Vacuum suddenly shuts off after a few minutes but restarts after cooling down.
Thermal Cut‑Out Activation
Symptom
Vacuum will not turn on at all, no lights, no sound.
