E1
Vacuum will not start; display shows E1 shortly after pressing the power button.
Main Battery Pack Protection Trip
E2
Vacuum stops during use and displays E2; motor does not restart until power is cycled.
Motor Overcurrent / Overload Protection
E3
Vacuum runs briefly, then stops and shows E3; brush roll in the motorized head does not spin.
Brush Motor Overload / Stall Detection
E4
Vacuum will not run and displays E4; sometimes appears after long continuous use.
Main Motor Overheating Protection
E5
Vacuum does not respond to the trigger or power button; E5 appears on the display when the battery is inserted.
Battery Temperature Fault
E6
Vacuum powers on but shuts off within a few seconds and shows E6; sometimes accompanied by flickering LEDs.
Main Control PCB Communication / Sensor Error
E7
Vacuum runs but suction is weak and the display shows E7; sometimes accompanied by a filter icon.
Airflow Restriction / Filter Blockage Detected
E8
Vacuum cannot switch to high/turbo mode; E8 appears when attempting to change power level.
Power Mode Switching / Current Limit Fault
E9
Vacuum display shows E9 and the unit will not start; sometimes occurs after the unit was dropped.
Internal Sensor / Orientation Fault
F1
Charger LED flashes a specific pattern and the vacuum battery will not charge; charger or manual indicates F1.
Charger Overvoltage / Battery Identification Error
F2
Charger LED indicates F2 or a temperature warning; battery will not charge or stops charging prematurely.
Battery Temperature Out of Range During Charging
F3
Charger immediately stops charging and indicates F3; battery never reaches full charge.
Battery Cell Voltage Imbalance / Fault
Symptom
Brush roll in the motorized head does not spin, but suction is present.
Brush Roll Drive Failure
Symptom
Dust escapes from the dust cup area when the vacuum is bumped or tilted.
Dust Cup Latch / Seal Failure
Symptom
Extension pipe or joints wobble or disconnect easily during use.
Mechanical Coupling Wear
Symptom
LED battery indicator shows incorrect charge level (e.g., drops from full to low suddenly).
Battery Fuel Gauge Calibration Issue
Symptom
LED lights on the floor nozzle do not turn on, but the brush still spins.
Nozzle LED Circuit Failure
Symptom
Trigger or power button sticks or does not return smoothly.
Sticking Control Mechanism
Symptom
Vacuum cuts out intermittently during use; power drops in and out when moving the handle.
Intermittent Power Connection
Symptom
Vacuum does not charge when placed on the wall‑mount charging dock.
Dock Charging Failure
Symptom
Vacuum does not turn on at all; no lights or sounds when pressing the power button.
No Power / Dead Unit
Symptom
Vacuum emits a burning smell or very hot air from the exhaust.
Overheating Motor / Blocked Airflow
Symptom
Vacuum handle or body becomes uncomfortably hot to touch during normal use.
Excessive Internal Heat Build‑Up
Symptom
Vacuum has very weak suction even though the motor sounds normal.
Airflow Restriction / Loss of Sealing
Symptom
Vacuum is excessively loud compared to normal operation.
Mechanical Noise / Bearing Wear
Symptom
Vacuum leaves fine dust blowing out from the sides or exhaust.
Filter Bypass / Damaged Filter Seal
Symptom
Vacuum leaves lines of debris behind and does not pick up well from carpets.
Poor Agitation / Brush Roll Performance
Symptom
Vacuum makes a high‑pitched whistling noise during use.
Air Leak / Partial Blockage
Symptom
Vacuum occasionally gives a static shock when touched after use.
Static Electricity Build‑Up
Symptom
Vacuum produces a rattling or clunking noise from the floor nozzle.
Nozzle Mechanical Damage
Symptom
Vacuum runs for only a few minutes on a full charge before shutting off.
Battery Capacity Degradation
Symptom
Vacuum runs only in low power mode and will not switch to higher modes (no error code shown).
Power Mode Control / User Interface Fault
Symptom
Vacuum shuts off when tilted to certain angles (e.g., when cleaning high areas).
Tilt Sensor / Orientation Protection Behavior
Symptom
Vacuum smells musty or emits an unpleasant odor during use.
Contaminated Filters / Dust Cup
