Hello, here are possible reasons why the robot stops midway:
The robot goes into sleep mode after getting stuck outside.
The robot fails to charge at the base and powers off due to drained battery. This may happen if the base station is not powered on or there is poor contact between the robot and the base.
If the above points are ruled out, there may be an internal fault of the main unit.
