Yeedi Robot Vacuums Error Codes

E1

Robot vacuum reports E1 and will not start cleaning; often accompanied by a voice prompt about a stuck main brush or brush error.

Main Brush Obstruction / Overload

E10

Robot vacuum shows E10 and will not start; often described as LDS/LiDAR error on mapping-capable Yeedi models.

LiDAR (Laser Distance Sensor) Rotation Failure

E11

Robot vacuum reports E11 and stops; often associated with gyroscope or internal navigation sensor error on non-LiDAR Yeedi models.

IMU / Gyroscope Calibration Failure

E12

Robot vacuum displays E12 and stops; often related to overcurrent or overload on one of the motors (brush, fan, or wheels).

Motor Overcurrent Protection Triggered

E13

Robot vacuum announces E13 and stops; often associated with over-temperature protection, especially after long runs or blocked airflow.

Thermal Overload of Fan or Main Board

E14

Robot vacuum shows E14 and cannot find or use the charging dock properly.

Charging Dock Detection / IR Receiver Fault

E15

Robot vacuum reports E15 and stops; often related to Wi-Fi or communication module error.

Wi-Fi Module Communication Failure

E16

Robot vacuum displays E16 and stops; often associated with stuck or misdetected top cover or sensor cover (on some Yeedi models with removable covers).

Top Cover / Sensor Cover Switch Error

E17

Robot vacuum reports E17 and stops; often related to floor tracking sensor error (downward optical sensor).

Optical Floor Tracking Sensor Blocked / Faulty

E18

Robot vacuum shows E18 and stops; often associated with water tank error on mopping models (tank not detected or empty).

Water Tank Detection / Flow Error

E19

Robot vacuum reports E19 and stops; often related to overfilled dustbin or airflow sensor error.

Dustbin Full / Airflow Sensor Fault

E2

Robot vacuum reports E2 and stops; often described as side brush error or side brush stuck.

Side Brush Obstruction / Motor Overload

E20

Robot vacuum displays E20 and stops; often associated with main board communication error between modules.

Internal Communication Bus Failure

E3

Robot vacuum announces E3 and stops; typically associated with wheel error or wheel stuck.

Drive Wheel Obstruction / Stall

E4

Robot vacuum reports E4 and stops, often near edges or stairs; may be described as cliff sensor error or anti-drop sensor blocked.

Cliff Sensor Blockage / Misreading

E5

Robot vacuum announces E5 and stops; often associated with bumper error or collision sensor stuck.

Front Bumper Stuck / Collision Sensor Fault

E6

Robot vacuum shows E6 and refuses to start; often related to dustbin not installed or dustbin sensor error.

Dustbin Presence Detection Failure

E7

Robot vacuum reports E7 and stops; commonly linked to fan error or suction motor fault.

Vacuum Fan Motor Failure / Blockage

E8

Robot vacuum displays E8 and stops; often associated with low battery protection or battery error.

Battery Pack Fault / Undervoltage

E9

Robot vacuum announces E9 and stops; often related to stuck or misinstalled mop module on Yeedi hybrid mop/vac models.

Mop Module Detection / Obstruction Error

Symptom

Robot vacuum cannot find the charging dock and stops in the middle of the floor with low battery.

Dock Homing / Return-to-Base Failure

Symptom

Robot vacuum does not power on at all; no lights, no sounds, even when placed on the charging dock.

No Power / Dead Robot

Symptom

Robot vacuum emits a musty or moldy odor, especially when mopping.

Biological Growth in Water Tank or Mop Cloth

Symptom

Robot vacuum frequently gets stuck on low thresholds, rugs, or cables.

Mobility / Obstacle Negotiation Issue

Symptom

Robot vacuum frequently reports that the dustbin is full even when it is nearly empty (no explicit code shown).

False Dustbin Full Detection

Symptom

Robot vacuum is excessively loud from the fan area, with a roaring or buzzing sound.

Fan Motor Bearing Wear / Imbalance

Symptom

Robot vacuum leaves streaks or dirty patches on the floor when mopping.

Poor Mopping Performance

Symptom

Robot vacuum leaves visible dust trails along walls or in corners.

Edge Cleaning Inefficiency

Symptom

Robot vacuum leaves wet puddles under or around the unit when docked or stored.

Water Tank Leakage

Symptom

Robot vacuum makes loud grinding or rattling noises from the brush area during operation.

Main Brush Bearing / Gearbox Noise

Symptom

Robot vacuum occasionally shuts off abruptly during cleaning without returning to the dock.

Intermittent Power Loss

Symptom

Robot vacuum powers on but will not start cleaning; pressing the start button or using the app does nothing.

Start Command / Mode Lockout

Symptom

Robot vacuum produces a high-pitched whine or squeal from the wheels while moving.

Drive Wheel Bearing Wear / Contamination

Symptom

Robot vacuum repeatedly bumps into furniture and seems to navigate poorly, missing areas or getting lost.

Navigation / Mapping Degradation

Symptom

Robot vacuum runs but leaves a lot of debris behind; suction seems weak compared to normal.

Reduced Suction Performance

Symptom

Robot vacuum smells like burning plastic or hot electronics during or after use.

Overheating Component / Electrical Smell

Symptom

Robot vacuum starts but stops after a few seconds and returns to the dock without cleaning much.

Premature Return to Dock / Battery or Navigation Issue

Symptom

Robot vacuum's app map shows incorrect room shapes or the robot appears to drive through walls virtually.

Mapping Data Corruption / Sensor Misalignment

Symptom

Robot vacuum's buttons on the top (power, home, spot) are unresponsive or require very hard presses.

Top Button Panel / Keypad Failure

Symptom

Robot vacuum's clock, schedules, or Wi-Fi settings reset frequently.

Settings Retention / Memory Issue

Symptom

Robot vacuum's voice prompts are distorted, very quiet, or absent, but it still cleans.

Speaker / Audio Output Fault
