Why does the GOAT return to the docking station before mowing is complete?

(1) The map is too large and cannot be covered in a single mowing cycle, so the robot needs to return and recharge. It will continue with the unfinished task when its battery level is sufficient.
(2) It may trigger underlight, animal protection, rain sensor, etc., so that the machine needs to stop working midway and return to the charging station first;
(3) Please check the App and the notifications to see if there are any errors or faults with the GOAT.
