Robot vacuum displays E11 and stops when transitioning between floor types or over thresholds.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Lift sensor misreading due to debris, Chassis flex sensor fault, Firmware miscalibration

Safety first: Turn OFF the robot and place it upside down.

Clean underside sensors: Wipe all underside sensors (cliff, floor tracking, and any lift sensors) with a dry microfiber cloth.
Check for warped parts: Inspect the bottom shell for cracks or warping that might cause the robot to think it is lifted.
Test on flat surface: Place the robot on a perfectly flat hard floor and start a cleaning cycle. Avoid thick thresholds during testing.

If E11 continues on flat floors, a lift or chassis sensor inside the robot may need calibration or replacement.
