How your robot avoids height differences
Before first use
Mounting the side brushes
3 Wall-following pattern
4 Spot-cleaning pattern
In its auto cleaning mode, the robot uses these patterns in a fixed
sequence:z-pattern, random pattern, wall-following pattern, and spot-
cleaning pattern.
When the robot has completed this sequence of patterns, it starts moving in
Z-pattern again. The robot continues to use this sequence of patterns to
clean the room until the rechargeable battery runs low, or until it is switched
off manually.
Note: You can also select each mode individually in the app.
The robot has three drop-off sensors in its bottom. It uses these drop-off
sensors to detect and avoid height differences such as staircases.
Note: It is normal for the robot to move slightly over the edge of a height
difference, as its front drop-off sensor is located behind the bumper.
Caution: In some cases, the drop-off sensors may not detect a staircase or
other height difference in time. Therefore monitor the robot carefully the
first few times you use it, and when you operate it near a staircase or
another height difference. It is important that you clean the drop-off
sensors regularly to ensure the robot continues to detect height
differences properly (see chapter ' Cleaning and maintenance' for
instructions).
1 Unpack the side brushes and place the robot upside down on a table or
on the floor.
