The robot is equipped with sensors that de-
tect stairs and prevent the robot from falling
down.
Using a special carpet fringe program the
robot does not get stuck in carpet fringes.
Thanks to the different angles, it also finds
it way out of narrow corners.
It is most efficient to let the robot clean indi-
vidual rooms, i.e. station and robot are lo-
cated within the same room. This reduces
the searching time during the return to the
station, the share of the effective cleaning
time is, therefore, the highest possible.
If you want to clean entire floors, the station
should be placed at a central spot of the
apartment to enable the robot to easily re-
turn to the station.
No, but due to the continuous cleaning, the
formation of dirt is substantially reduced.
Thus, an accumulation of dirt in corners is
effectively avoided.
Stairs : The robot works with optical sen-
sors that detect half-landings and signal the
robot that it must change its direction.
Steps : The robot is able to deal with hard
steps up to 10 mm and soft steps up to
20 mm in both directions.
No. Damages of the items of furniture can
be excluded.
Please note, however, the lightweight and
fragile objects may be touched and moved
by the robot. Objects that are equipped with
a cable, may be pulled down from furniture
(e.g. telephone). It is important to prepare
the room in such a manner that it is suitable
for robots.
As the robot is not noisy and does not work
with ultrasound, problems with pets are not
to be expected. The self-movement behav-
iour only arises the mistrust of the pets.
The robot should not be left unattended if
children are playing in the same room. Me-
chanical damages are likely if children sit
on the robot while it is in operation.
The robot is only able to get out of tricky sit-
uations to a certain degree. Piled cables
can induce him to hopeless manoeuvres. In
this case the robot turns off automatically
after a specific period of time. The red sig-
nal on the robot lights up quickly.
The best solution is to place the robot on a
free area and turn it off and on again. Then,
it continues its cleaning run without prob-
lems.
You can lift the robot from the floor using
both hands, or you carry it by putting one
hand into the relief of the brush.
As a result, the filter becomes blocked. You
have to remove the filter from the robot and
clean it (see Chapter "
Cleaning flat filter “).
Nothing can happen. The robot stops at this
point and displays the signal for being
stuck. If no more light is blinking, the batter-
ies are depleted and must be recharged.
Which tools are present that help the ro-
bot to cope with obstacles?
What is the most efficient way to operate
the robot (individual rooms, entire apart-
ment)?
Are corners cleaned without any prob-
lems (the robot is round)?
What happens at stairs/steps?
Caution:
Do not leave loose objects (e.g.: newspa-
pers, clothing) on stairs or steps, as this
will inhibit the function of the sensors. –
Risk of falling!

tions?
