The robot is fitted with three drop-off sensors in the bottom. These drop-off sensors are used to detect and avoid height differences. In some cases, depending on specific circumstances in your home, the drop-off sensors may not detect a staircase or other height difference in time. Therefore avoid using the robot in these situations or monitor it carefully.
Note: To ensure proper detection of stairs, steps or other height differences, clean the sensors in the bottom of the robot regularly.
