How your robot cleans
Cleaning system
The robot has a 2-stage cleaning system to clean your floors efficiently.
- The two side brushes help the robot clean in corners and along walls. They also help to remove dirt
from the floor and move it towards the suction opening (Fig. 4).
- The suction power of the robot picks up loose dirt and transports it through the suction opening
into the dust container (Fig. 5).
Cleaning patterns
In its auto cleaning mode, the robot uses an automatic sequence of cleaning patterns to clean each
area of the room optimally. The cleaning patterns it uses are:
1 Z-pattern or zigzag pattern (Fig. 6)
2 Random pattern (Fig. 7)
3 Wall-following pattern (Fig. 8)
4 Spot-cleaning pattern (Fig. 9)
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 by pressing the appropriate button on the remote
control. For more details, see chapter 'Using your robot', section 'Cleaning modes'.
How your robot avoids height differences
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).

Before first use

Mounting the side brushes
1 Unpack the side brushes and place the robot upside down on a table or on the floor.
2 Push the side brushes onto the shafts on the bottom of the robot (Fig. 10).
Note: Make sure you attach the side brushes properly. Press them onto the shaft until you hear
them lock into position with a click.
Removing the protection tag from the remote control
The remote control works on a CR2025 coin-shaped battery. This battery is protected with a
protection tag that has to be removed before use.
