E1
Robot vacuum beeps and reports E1; unit will not start cleaning and may say the drop sensors are dirty or the robot is near a ledge even on flat floor.
Cliff / Drop Sensor Obstruction or Failure
E10
Robot vacuum reports E10 and refuses to start cleaning; often described as battery error or power system fault.
Battery Pack or Power Management Fault
E11
Robot vacuum reports E11 and may not dock or charge properly; sometimes associated with charging error.
Charging Circuit or Docking Contact Fault
E12
Robot vacuum reports E12 and may not connect to Wi-Fi or app; sometimes shown as Wi-Fi module error.
Wi-Fi Module or Communication Fault
E13
Robot vacuum reports E13 and may not start mapping or navigation; sometimes associated with LDS/LiDAR error on mapping models.
Laser Distance Sensor (LDS) Obstruction or Failure
E14
Robot vacuum reports E14 and may stop mid-clean; sometimes related to cliff sensor calibration or dark floor detection issues.
Cliff Sensor Calibration / False Drop Detection
E15
Robot vacuum reports E15 and may not start; sometimes associated with internal communication error between modules.
Internal Communication Bus Error
E2
Robot vacuum reports E2 and stops; it may say the bumper is stuck or front bumper error.
Front Bumper Stuck or Bumper Switch Fault
E3
Robot vacuum reports E3 and stops; often described as wheel stuck, side wheel error, or wheel suspended.
Drive Wheel Stall or Suspension Error
E4
Robot vacuum reports E4 and stops; often described as side brush error or side brush stuck.
Side Brush Motor Stall
E5
Robot vacuum reports E5 and stops; often described as rolling brush error or main brush stuck.
Main Brush Motor Stall
E6
Robot vacuum reports E6 and will not start; often described as dustbin missing or dust collector error.
Dustbin Presence Sensor Fault
E7
Robot vacuum reports E7 and stops; often associated with fan error or suction motor fault.
Suction Fan Motor Failure
E8
Robot vacuum reports E8 and may shut down; often related to overheating or high-temperature protection.
Overheat Protection Triggered
E9
Robot vacuum reports E9 and may not move correctly; often associated with gyro or navigation error on some Eufy models.
Gyroscope / IMU Calibration Failure
Symptom
Robot vacuum does not avoid virtual boundaries or magnetic strips (if supported).
Boundary Sensor or Magnetic Strip Detection Failure
Symptom
Robot vacuum does not detect or avoid stairs and may approach edges dangerously.
Cliff Sensor Non-Detection
Symptom
Robot vacuum does not power on at all; no lights, no sounds, even when placed on the charging base.
Complete Power Loss
Symptom
Robot vacuum does not respond to Wi-Fi commands or app control, but cleans normally via buttons.
Wi-Fi Connectivity Loss
Symptom
Robot vacuum emits a burning smell or becomes unusually hot during or after cleaning.
Overheating Motor or Electrical Component
Symptom
Robot vacuum frequently stops and reports that it is stuck, even on open floor with no visible obstacles.
False Stuck Detection
Symptom
Robot vacuum gets stuck frequently on low thresholds, rugs, or small obstacles, more than it used to.
Reduced Mobility / Obstacle Handling
Symptom
Robot vacuum is very loud during operation, with grinding or rattling noises from the underside.
Mechanical Noise from Brush or Drive Train
Symptom
Robot vacuum leaves fine dust trails or blows dust out of the exhaust.
Filtration Failure / Dust Leakage
Symptom
Robot vacuum leaves lines of debris or clumps of hair behind, especially along its path.
Ineffective Debris Pickup
Symptom
Robot vacuum powers on but will not start cleaning; it beeps or returns to base immediately without an error code.
Start Inhibit Due to Low Battery or Sensor State
Symptom
Robot vacuum repeatedly fails to find or dock with the charging base; it wanders nearby or misses alignment.
Docking / Home Base Location Failure
Symptom
Robot vacuum runs but has very weak suction; it leaves debris behind even though brushes are spinning.
Reduced Suction Performance
Symptom
Robot vacuum spins in circles or cannot drive straight; it may veer strongly to one side.
Drive Wheel Speed Imbalance or Encoder Fault
Symptom
Robot vacuum starts but shuts off after a few minutes with a low runtime, even after a full charge.
Battery Capacity Degradation
Symptom
Robot vacuum’s clock, schedule, or cleaning history resets frequently.
Non-Volatile Memory or Backup Power Issue
Symptom
Robot vacuum’s front caster wheel does not swivel or roll freely, causing dragging and navigation issues.
Front Caster Wheel Seizure
Symptom
Robot vacuum’s main brush does not spin, but side brush and movement are normal; no specific error code.
Main Brush Drive Failure Without Code
Symptom
Robot vacuum’s side brush flies off during cleaning or frequently comes loose.
Side Brush Retention Failure
Symptom
Robot vacuum’s top buttons (Start, Home, Spot) do not respond or require excessive force.
Top Control Button Failure
Symptom
Robot vacuum’s voice prompts or beeps are distorted, very quiet, or absent.
Speaker or Audio Circuit Failure
Symptom
Robot vacuum’s wheels slip and spin on smooth floors, causing poor navigation and cleaning coverage.
Loss of Traction on Drive Wheels
