Ultenic False Stuck Detection

Robot vacuum frequently reports 'stuck' even on open, flat floors.

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

Faulty bumper switch, IMU miscalibration, Dirty cliff sensors, Loose internal wiring causing false triggers

Safety first: Turn OFF the robot.

Clean sensors and bumper: Wipe cliff sensors and ensure the bumper moves freely and returns evenly.
Reboot and recalibrate: Power cycle the robot on a flat surface and, if available, run sensor calibration via the app.
Check for rattling: Gently shake the robot to listen for loose internal parts that might trigger sensors.
If false stuck alerts continue: The bumper switch assembly or IMU may be faulty and require replacement.
