Symptom
Vacuum attachments (crevice tool, dusting brush) fall off easily during use.
Accessory Latch Wear
Symptom
Vacuum bin fills very quickly and performance drops after a short time.
Cyclone Separation Inefficiency
Symptom
Vacuum does not respond to app scheduling or remote start commands, but cleans normally when started manually.
Cloud / App Control Communication Issue
Symptom
Vacuum emits a burning smell during operation.
Electrical Overheating / Motor or Brush Motor Failure
Symptom
Vacuum handle or body becomes uncomfortably hot during normal use.
