Main Brush Motor Overload / Blockage
E9
Robot vacuum displays E9 and stops, often with a full dustbin or poor suction.
Dustbin / Airflow Sensor Error
Symptom
Robot vacuum cannot find its way back to the dock and often stops with low battery in random locations.
Dock Localization / Navigation Degradation
Symptom
Robot vacuum does not power on at all; no lights or sounds when pressing the power button.
No Power / Dead Robot
Symptom
Robot vacuum emits a burning smell or becomes very hot to the touch during operation.
Overheating Motor or Electrical Component
Symptom
Robot vacuum frequently gets stuck on rugs, thresholds, or cables and cannot free itself.
Obstacle Handling / Ground Clearance Issue
Symptom
Robot vacuum frequently reports that it is near a cliff or refuses to clean dark carpets, even on flat floors.
Overly Sensitive Cliff Sensors
Symptom
Robot vacuum is not picking up hair or debris along edges and corners.
Side Brush Inefficiency
Symptom
Robot vacuum is very loud during operation, with grinding or rattling noises from the bottom.
Mechanical Noise from Brush or Wheel Assemblies
Symptom
Robot vacuum leaves clumps of hair or debris behind the main brush area.
Main Brush Guard / Seal Inefficiency
Symptom
Robot vacuum leaves streaks or wet patches and does not mop evenly on mopping-capable models.
Uneven Mopping / Water Distribution Issue
Symptom
Robot vacuum leaves visible dust and debris on the floor and has weak suction.
Reduced Suction Performance
Symptom
Robot vacuum often stops with the message that the dustbin is missing, even when it is installed.
Dustbin Presence Detection Failure
Symptom
Robot vacuum randomly stops and restarts or reboots during cleaning without an error code.
Intermittent Power / Connection Issue
Symptom
Robot vacuum runs but moves in circles or has difficulty driving straight.
Drive Wheel Speed / Encoder Imbalance
Symptom
Robot vacuum runs for a very short time (5–15 minutes) and then returns to dock or shuts off, even after full charging.
Battery Capacity Degradation
Symptom
Robot vacuum smells musty or unpleasant during operation, especially when mopping.
Odor from Dustbin, Filter, or Mop Pad
Symptom
Robot vacuum’s app map is inaccurate, with missing rooms or distorted walls.
Mapping / SLAM Algorithm Inaccuracy
Symptom
Robot vacuum’s front caster wheel does not rotate freely, causing drag or squeaking.
Front Caster Wheel Seizure
Symptom
Robot vacuum’s voice prompts or beeps are distorted or silent, but it otherwise operates.
Speaker / Audio Output Failure
Symptom
Robot vacuum’s wheels slip or spin in place on smooth floors.
Reduced Traction on Drive Wheels
