Ambrogio Delayed Blade Stop / Motor Control Issue

Robot lawnmower blades continue to spin for an unusually long time after pressing STOP

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

Firmware bug in motor control, Sticking blade relay, Faulty MOSFET on main board, STOP button contact delay

Danger: This is a safety-related issue. Keep hands and feet away from the blade area.

Observe delay: Time how long the blades take to stop after pressing STOP. It should be nearly immediate.
Update firmware: Install the latest Ambrogio firmware, as some stop-delay issues are software-related.
Inspect STOP button: Ensure the STOP button moves freely and is not sticking mechanically.
If delay remains excessive: The main control board's motor driver or relay may be faulty and should be replaced by a qualified technician.
