Robot vacuum stops and displays E2; unit may spin in place or fail to move forward.

Safety first: Power off the robot and remove it from the dock. Work on a clean, flat surface.

• Inspect drive wheels: Check both left and right wheels for wrapped hair, string, or carpet fibers. Rotate each wheel by hand; they should spring up and down and spin freely.
• Clean wheel wells: Use tweezers or a small brush to remove debris from around the wheel axles and inside the wheel wells.
• Check wheel suspension: Press each wheel up and release; it should move smoothly. If it sticks, inspect for lodged debris or bent plastic.
• Test movement: Power the robot back on and start a short cleaning cycle on a hard floor to see if the error clears.
• If E2 returns: The affected drive wheel motor or gearbox may be failing. Replace the left or right drive wheel module as a complete assembly. This usually requires removing the bottom cover and disconnecting a wiring harness.
