Symptom
The dirt cup will not latch securely or falls off during use.
Dust Cup Latch Failure
Symptom
The powered mini turbo tool (pet tool) does not spin when attached, but the main floor head works.
Accessory Motor/Connection Failure
Symptom
The vacuum body or handle creaks and flexes excessively during use.
Housing/Chassis Fatigue
Symptom

Symptom
The vacuum will not stay on the wall mount or dock, falls off easily, and sometimes does not charge.
Docking/Mounting Misalignment
Symptom
The vacuum's runtime is much shorter than specified, even after a full charge.
Reduced Battery Capacity/High Load
Symptom
Vacuum emits a burning smell during use.
Electrical Overheating / Component Failure
Symptom
Vacuum handle or body becomes uncomfortably hot where you hold it.
Localized Overheating / Poor Heat Dissipation
Symptom
Vacuum hose collapses or kinks easily, reducing suction.
Hose Structural Failure
Symptom
Vacuum leaves lines of debris behind and does not pick up well from carpet.
Poor Agitation / Worn Brushroll
Symptom
Vacuum makes a grinding or rattling noise from the floor nozzle when the brushroll is engaged.
Brushroll Bearing or Gear Damage
Symptom
Vacuum powers on but has very weak suction; motor sounds normal.
