Robomow Over‑Sensitive Obstacle Detection

Robomow stops mowing when it encounters light obstacles like tall grass or small branches, instead of pushing through.

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 bumper, Weak bumper springs, Faulty bumper sensor, Excessive deck height causing early contact

Safety first: Turn OFF the mower before inspecting the bumper.

Check bumper movement: Ensure the bumper moves freely and returns to its rest position.
Inspect springs: Replace any broken or weak bumper springs.
Adjust cutting height: Raise the cutting height slightly to reduce deck contact with tall grass.
Test operation: After adjustments, run the mower and observe how it handles light obstacles.
Persistent oversensitivity: The bumper sensor strip may need replacement.
