Robot mower occasionally shuts down when hitting bumps, then restarts when moved.

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

Loose battery pack, Poor contact at battery terminals, Cracked PCB or connector, Worn main switch contacts

Safety first: Turn OFF the mower and remove the battery before inspection.

Steps:

1. Secure battery: Ensure the battery is firmly held in its compartment and cannot move when the mower bumps.
2. Tighten connectors: Check that battery and switch connectors are tight and latch properly.
3. Inspect for cracks: Look for cracks in the PCB around heavy components; replace the PCB if found.
4. Replace switch: If the main switch feels loose or intermittent, replace it.
