ENGLISH
4 Place the home station on a flat and firm
indoor floor and fix it to a suitable wall in your
selected location.
• Remove all obstacles from around the
home station.
5 Connect the adapter to a wall outlet.
NOTE
• If two robot cleaners are used together, there
should be at least 1.5 m distance between home
stations.
- If the home stations are too close together,
the robot cleaner may not be able to return to
its home station.
• Do not install the home station on a carpet.
• If the charging station is not plugged into a
power outlet, the Robot Cleaner battery will not
charge.
• Do not install the charging station in a narrow
space. Doing so will make it difficult for the

cleaner from behind.
• When charging begins, the status indicator
on the Robot Cleaner will blink pink.
• The robot cleaner returns to the home
station on its own to charge the battery
when cleaning is finished or battery
becomes low. If the robot cleaner returns to
the home station due to low battery, it will
resume cleaning after the battery is fully
charged.
NOTE
• The battery is a consumable. The battery life and
service life will decrease based on the years of
usage and hours of use.
• If the robot cleaner cannot be charged normally,

edit the area and set the area to be cleaned.
• Set the cleaning prohibited area to prevent the
robot vacuum from falling or being constrained
to clean.
- If it falls on the toilet or hallway
- If you are constrained by a threshold or under
a sofa
• When setting the cleaning prohibited area,
consider the movement error and set the
prohibited area large.
• If you set the no-clean area while the product is
running, it stops cleaning and sets the
prohibited area. At this time, you can continue
cleaning after setting the prohibited area in a
paused state during cleaning.
• If you want to save the drawing and prohibited
area settings, press the power button of the
