Possible Causes

Wheel motor overloaded by slope or obstacles, Internal short in motor windings, Gearbox binding, Debris wrapped around axle

How to Fix / Troubleshooting

Safety first: Immediately turn OFF the robot and disconnect from charging. Allow it to cool before touching the motors.

  • Inspect wheels: Remove grass, string, or debris from around the wheel axles and hubs.
  • Check for free movement: Once cool, rotate each wheel by hand. If one is significantly stiffer, its motor or gearbox may be failing.
  • Reduce load: Exclude very steep or rough areas from the mowing zone by adjusting the perimeter wire.
  • Replace suspect motor: If the smell returns or the motor becomes very hot quickly, replace the affected Ambrogio wheel motor assembly.
