Q10. Fail to return to the charging base.
* Remove any objects near the charging base that block the robotic vacuum going back for recharging.
* If the charging base is located far away, the robotic vacuum will need more time to return. Please be patient as it works its way back.
* Make sure the battery level is not critically low or empty.
* Clean the sensors on the bumper of the robotic vacuum and the charging base.
