Possible Causes

Hair or threads wrapped around left wheel, Left wheel stuck in extended or retracted position, Left drive motor gearbox jammed, Left wheel motor cable loose on main board

How to Fix / Troubleshooting

Safety first: Turn OFF the robot and remove it from the dock. Flip it over on a towel.

Step-by-step:

  • Inspect the left wheel: Spin the left drive wheel by hand. It should rotate smoothly with some resistance. If it is hard to turn or locked, proceed to cleaning.
  • Remove wrapped debris: Use scissors or tweezers to cut and pull out hair, threads, or carpet fibers wrapped around the wheel axle and in the wheel well.
  • Check wheel suspension: Press the wheel up and down. It should move freely and spring back. If it sticks, clean the cavity around the wheel with a small brush.
  • Clean wheel treads: Wipe the rubber tire with a damp cloth to remove dust and slippery residue.
  • Power cycle and test: Turn the robot back ON, place it on the floor, and start a cleaning cycle. Observe whether the left wheel turns.

If E3 remains: The left drive motor or its wiring may be damaged. Replacing the left wheel motor assembly usually resolves this but requires opening the chassis and disconnecting the motor harness from the main PCB.
