Frequently Asked Questions
Which floor coverings is the robot suita-
ble for?
The robot can be used on all common sur-
faces, such as carpets and hard surfaces
(tiles, parquetry, etc.). With respect to ex-
tremely deep-piled carpets (> 20 mm), spe-
cific restrictions apply. The moving
sweeping edge is automatically adjusted to
different floor coverings.
Is it difficult to clean underneath pieces
of furniture?
No. Due to its compact and flat design the
robot is able to clean underneath pieces of
furniture, such as beds, sofas, and ward-
robes.
How does the robot transport the ab-
sorbed dirt to the station?
The robot is equipped with a dirt receptacle
that is regularly emptied by the station.
How is the dirt absorbed in the station?
In the station, the dirt is collected in a con-
ventional filter bag (2 litres).
The exchange intervals are flexible and are
reported to the user in a timely manner by
means of a indicator lamp on the display.
How much dirt can the robot absorb?
In case of a normal degree of soiling, the
dirt receptacle is sufficient for one hour of
cleaning. If this should not be sufficient in
the individual case, the robot simply returns
to the station earlier, disposes of the dirt
and carries on working.
How is the absorption of dirt in the robot
performed?
The dirt is swept into the dirt receptacle of
the robot by means of vacuum-supported
sweeping.
Can the robot clean in the apartment /
house without supervision?
Yes, this is possible without any problems.
The robot is an autonomous system and
does not require any intervention. The dirt
receptacle is emptied at the station.
How long does it take until the robot is
charged or operative?
The charging time is between 15 and
60 minutes according to the charging state
of the battery before the charging. In case
of the initial operation, the robot certainly
has the longest charging time.
At which speed does the robot move?
By default, the robot runs at 20 cm per sec-
ond. If it cleans very dirty spots, the speed
is reduced by half to intensify the cleaning.
The same applies to the final approach to
the station to allow the robot to precisely
manoeuvre in.
How many square meters can the robot
clean within one hour?
The robot can clean up to 15 qm per hour.
Many spots, in particular the frequently
used paths are cleaned repeatedly from dif-
ferent directions.
How does the robot know when it must
return to the station?
The robot returns to the station as soon as
the battery voltage has reached a specific
level or if the dirt receptacle is full.
How long does it take to empty the robot
at the station?
The process takes approximately 30 sec-
onds.
Where is the robot programmed? What
do I have to pay attention to?
The robot can only be turned on or off. You
can select the cleaning duration at the sta-
tion. In addition, you can specify that the ro-
bot should not leave the station after the
next approach to the station (parking func-
tion).
According to which principle does the
robot move?
The robot moves through the room according
to the random principle. If he bumps into an
obstacle, it turns at any angle and then goes
straight until it bumps into the next obstacle.
