3 If the dry wipe is to dirty to use again, pull the fixation blocks out of the dry wipe attachment and
dispose of the dry wipe.
Note: You cannot rinse or wash the dry wipes.
Using the invisible wall (FC8822 only)
You can use the invisible wall to prevent the robot from entering a room or area that you want to keep
it out of.
Placing the batteries in the invisible wall
The invisible wall operates on four AA batteries.
1 Push the two release tabs at the bottom of the back cover (1) and slide the back cover upwards
and off the invisible wall (2) (Fig. 32).
2 Take four new AA batteries from the pack and insert them into the battery compartment of the
invisible wall (Fig. 33).
Note: Make sure the + and - poles of the batteries point in the right direction.
3 Slide the back cover onto the invisible wall again (Fig. 34).
Positioning the invisible wall to stop the robot
1 Place the unit at a point you do not want the robot to cross, e.g at an open door to a room that is
off-limits to the robot (Fig. 35).
2 Switch on the invisible wall with the on/off slide on top of the unit (Fig. 36).
3 Start the robot.
4 When the robot comes too close to the invisible wall, the light on the invisible wall starts flashing
and the invisible wall emits a beam of infrared light. This beam of infrared light makes the robot
change its course and move away from the invisible wall (Fig. 37).
Note: If you use the invisible wall, regularly check if the batteries still contain sufficient power. You can
check this by switching the virtual wall off and on again. If there is enough energy in the batteries, the
LED on the invisible wall will light up briefly.

Cleaning and maintenance

Cleaning the robot
To maintain good cleaning performance, you have to clean the drop-off sensors, the wheels, the side
brushes and the suction opening from time to time.
1 Place the robot upside down on a flat surface
2 Use a brush with soft bristles (e.g. a toothbrush) to remove dust or fluff from the drop-off sensors
(Fig. 38).
Note: It is important that you clean the drop-off sensors regularly. If the drop-off sensors are dirty,
the robot may fail to detect height differences or staircases.
3 Use a brush with soft bristles (e.g. a toothbrush) to remove dust or fluff from the front wheel and
side wheels (Fig. 39).
4 To clean the side brushes, grab them by the bristles and pull them off their shafts (Fig. 40).
5 Remove fluff, hairs and threads from the shaft and from the side brush with a soft brush (e.g. a
toothbrush) or a cloth (Fig. 41).
