Powered Accessory Drive Failure
Symptom
Battery or handle area becomes excessively hot to the touch during use or charging.
Overheating Battery or Charging Circuit
Symptom
Battery runtime is significantly shorter than specified, even on low power.
Battery Capacity Degradation
Symptom
Brush roller does not spin, but suction is present and the vacuum motor runs normally.
Brush Drive Failure
Symptom
Dust and debris escape from the vacuum exhaust, or fine dust appears around the unit during use.
Filtration Failure / HEPA Bypass
Symptom
Dust bin will not latch securely or falls off during use.
Dust Bin Latch / Housing Damage
Symptom
LED lights on the floor head flicker or do not turn on, but the brush still spins.

Symptom
Vacuum intermittently cuts out when moving the wand or rotating the floor head.
Intermittent Electrical Connection in Wand or Head
Symptom
Vacuum leaves visible debris on the floor even after multiple passes.
Poor Pickup Performance
Symptom
Vacuum loses suction only when the floor head is attached; suction at the wand end is strong.
Floor Head Air Path Blockage
Symptom
Vacuum loses suction only when the wand is attached; suction at the main body is strong.
Wand Air Leak or Blockage
Symptom
Vacuum makes rattling or grinding noises from the floor head during operation.
Brush Head Mechanical Damage
Symptom
Vacuum motor pulses up and down in speed repeatedly during use without an error code.
Airflow Regulation / Partial Blockage
Symptom
Vacuum runs but has very weak suction even with a fully charged battery.
General Airflow Restriction / Loss of Suction
Symptom
Vacuum runs but makes a loud high-pitched whine from the main body.
Main Motor Bearing Wear / Air Leak Noise
Symptom
Vacuum shuts off after a few seconds of use without showing an error code.
Battery Voltage Sag / Protection Trip
Symptom
Vacuum vibrates excessively, especially when using the main floor head on hard floors.
