Installing the Home Station
Always keep the home station plugged in when in
use. If the home station is not plugged in, the robot
cleaner will not return to the home station to
charge automatically when the battery is low or
when the cleaning is completed.
1
Before use, remove both the foam strips from
behind the collision bumper.
• If the foam strip are not removed, it may be
difficult for the Robot Cleaner to find the
charging station or product performance
may be adversely effected, and may cause
damage to furniture and skirtings.
2
Remove the protective film attached to the
charging station and the Robot Cleaner.
• If the protective film is not removed, it may
be difficult for the Robot Cleaner to find the
charging station or product performance
may be adversely effected.
3
Install the charging station on top of the Floor
Damage Prevention Plate. Install the charging
station by lowering it into position.
4
Place the home station on a flat and firm
indoor floor and place it hard against a suitable
wall in your selected location. Do not install,
store or place the home station charging dock
or the robot cleaner in any outdoor or
sheltered outdoor location.
• Remove all obstacles from around the home
station.
5
Connect the power adapter to a wall outlet.

BEFORE USING
ENGLISH
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
Robot Cleaner to find the charging station.
• Make sure that the charging station is plugged
into a power outlet during use. If the power
supply is not connected to the charging station,
the Robot Cleaner cannot automatically returns
to the charging station to charge the battery
when it is low or when the cleaning is completed.
Charging the Robot Cleaner
Always keep the power plug of the home station
connected to an electrical outlet. The robot cleaner
can only find the home station for it to recharge
when power is supplied to the home station. If the
home docking station is moved while the robot
cleaner is cleaning, then it willnot be found by the
robot cleaner when it needs to return for re
charging or when cleaning is completed.
1
Turning on the Power Supply. Turn the main
power switch ON
a
at the back of the robot
cleaner to turn on the power supply.
2
Place the robot cleaner on the home station,
align the centre of the robot cleaner with the
centre of the home station and push the robot
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 without
presenting with a problem or malfunction, check
if the charging terminals are contaminated by a
foreign substance, and clean the home station
with a dry towel.
• If charging is still not available after cleaning,
check if the home station and the adapter are
connected properly.
• Fully charge the battery every 6 months when
not using the robot cleaner or if keeping in
storage for a long time.
- Storing the battery for a long period of time
without charging may cause battery failure.

Re-install the dustbin and water tank in place.
5
Install the mop on the mop holder.
• Before attaching the mop, wet the mop with
enough water and wring the mop.
6
Insert the mop holder into the bottom of the
robot cleaner until you hear a click.
CAUTION
• If the mop is excessively wet, the floor may
become slippery and cause people to slip.
• Do not leave the robot cleaner in the home
station or on the floor for a long time with wet
mop attached. Doing so may cause floor damage
or odours.
Drying the Water Tank and
Washing the Mop
It is recommended that after each use of the mop
holder, take out the mop holder from one side,
empty the water tank, rinse the mop with water,
and air dry it.
If you wish to completely remove remaining water
from the water tank, use the following additional
guidelines. This is recommended if the mopping
function is not used daily.
global_main.book.book Page 16 Monday, July 3, 2023 4:15 PM
17
OPERATION
ENGLISH
1) With the water tank in an upright position,
attach a paper towel or a cloth to the outlet
and remove remaining water.
2) Remove as much water from the water tank as
possible, tilt the water tank towards the water
tank stopper so as to collect the water, and
then dry it by laying it upside down on a paper
towel or a cloth.
CAUTION
• Do not use the mopping mode on any carpet.
• When the robot cleaner is being charged or idle,
please remove the mop holder.
• In order to achieve better mopping results, it is
recommended to sweep your floor three times
with the robot cleaner before installing the mop
holder.
• To avoid damaging your wood floor, please
make sure to take out the mop holder
immediately after floor mopping is complete. Or
install the home station onto the Floor Protector
Plate (optional).
• When mopping is paused or finished, the robot
cleaner will automatically cut off the water to the
mop pad. However, the mop remains wet and
should not be left attached as it can case odors.
Restarting the System
In standby mode, press and hold the home button
for 15 seconds to reset the system. After resetting
the system, the robot cleaner will lose the original
settings including the map and do not clean areas.

connection problems or any faults,
malfunctions, or errors caused by network
connection.
• The surrounding wireless environment can
make the wireless network service run slowly.
• If the appliance is having trouble connecting to
the Wi-Fi network, it may be too far from the
router. Purchase a Wi-Fi repeater (range
extender) to improve the Wi-Fi signal strength.
• The network connection may not work properly
depending on the Internet service provider.
• The Wi-Fi may not connect or the connection
may be interrupted because of the home
network environment.

disable the firewall or add an exception to it.
• The wireless network name (SSID) should be a
combination of English letters and numbers. (Do
not use special characters.)
• Smartphone user interface (UI) may vary
depending on the mobile operating system (OS)
and the manufacturer.
• If the security protocol of the router is set to
WEP
