Segway Reduced Obstacle Detection Sensitivity

Mower occasionally fails to detect obstacles and collides hard with trees or walls.

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

Stiff or misaligned front bumper, Dirty ultrasonic/ToF sensors, Firmware configuration issue, Damaged bumper springs

Safety first: Turn OFF the mower and disconnect power before inspecting sensors and bumper.

Test bumper response: Gently push the bumper and confirm it moves and returns freely. Adjust or replace springs if necessary.
Clean sensors: Wipe all front‑facing sensors with a soft cloth to remove dirt and grass film.
Update firmware: Install any available updates that may improve obstacle detection algorithms.
Reduce speed (if configurable): In the app, lower the mowing speed to reduce impact severity while troubleshooting.
