When a snow-blowing task starts, Yarbo first completes one full lap around the perimeter of the defined work area. This behavior is expected and part of the standard snow-clearing logic.
While clearing the perimeter:
This is why you may see snow being thrown back into the area during the first lap.
After the perimeter pass is completed:
Some users expect Yarbo to re-clean the perimeter after finishing the interior area. At the moment, Yarbo completes only one perimeter pass at the beginning of the task.
This feedback has been noted by the product team, and the option to perform a second perimeter pass after interior cleaning is being considered for future updates.
