Ambrogio Real-Time Clock / Backup Power Issue

Robot lawnmower occasionally loses time/date or schedule settings after being powered off

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

Weak RTC backup battery on main board, Firmware bug, Main board fault, Frequent full power disconnections

Safety first: Turn OFF the robot before opening the cover.

Avoid unnecessary power cuts: Use the main switch only when needed; leave the robot in standby when possible.
Update firmware: Install the latest Ambrogio firmware, as some RTC issues are software-related.
Inspect RTC battery (if present): Some boards have a small coin-cell battery. If accessible and allowed by Ambrogio, replace it with the same type and polarity.
If problem persists: The main control board may need replacement.
