Symptom
Crevice tool or soft brush has very low suction compared to the floor head.
Localized Blockage / Seal Issue in Attachments
Symptom
Dust bin door will not latch closed or pops open during use.
Dust Bin Latch Failure
Symptom
Fine dust escapes from exhaust, visible haze when vacuuming.
HEPA Filter Bypass / Damage
Symptom
LED indicators on the battery flicker or show inconsistent levels during use.
Battery Indicator / BMS Calibration Issue
Symptom
Mini motorized brush (for sofa/mattress) does not spin, but the main floor head works.
Accessory Motor Failure
Symptom
Motorized floor brush is very noisy, rattles, or vibrates strongly.
Brushroll Imbalance / Gearbox Wear
Symptom
Trigger must be pressed very hard or at a specific angle to start the vacuum.
Worn Trigger Mechanism
Symptom
Vacuum body creaks or flexes, with visible cracks after being dropped.
Structural Housing Damage
Symptom
Vacuum body or handle becomes uncomfortably hot to hold, even on low power.
Chronic Overheating
Symptom

Mounting / Docking Misalignment
Symptom
Vacuum does not respond to any buttons, but LEDs are on when charging.
Control Interface Failure
Symptom
Vacuum has very weak suction even though the motor sounds normal.
Air Leak / Loss of Sealing
Symptom
Vacuum intermittently cuts out when moving the wand or twisting the handle.
Intermittent Electrical Connection
Symptom
Vacuum leaves visible dust on floors and carpets despite a normal suction sound.
Brushroll Inefficiency / Floor Head Blockage
Symptom
Vacuum makes a loud, high-pitched whine or grinding noise during operation.
Motor Bearing Wear / Fan Damage
Symptom
Vacuum produces excessive vibration in the hand, especially at high power.
Rotating Assembly Imbalance
Symptom
Vacuum runs only for a very short time (1–3 minutes) on a full charge.
Battery Capacity Degradation
Symptom
Vacuum smells like burning plastic or hot electronics during use.
Overheating / Electrical Insulation Breakdown
Symptom
