BEFORE USING THE ROBOT CLEANER
Charging
Before Charging the Battery
•Charging takes place even if the main power
switch of the robot cleaner is turned off.
•The charging time depends on the status of the
battery.
•It takes approximately 4 hours to fully charge
the battery after it is completely discharged.
•Clean the charging terminals using a soft cloth.
If the charging terminals are dirty or covered
or obstructed with foreign material, the robot
cleaner may not be charged normally.
•Charging may not take place if the ambient
temperature is below 41°F (5°C). Charge the
robot cleaner indoors.
•If it is necessary to store the robot cleaner for
a long period of time, fully charge the battery
every 6 months.
•Storing the robot cleaner for a long period of
time without periodically charging the battery
may cause a battery malfunction.
•If cleaning is not started from the home station
or you lift and move the robot cleaner, it may
take a longer time to find the home station.
Battery Level Indicator
•The battery level is indicated on the control
panel, as follows.
−The remaining battery level is displayed in
3 stages (r s t) according to the
amount of power remaining.
−The battery level indicator flashes when the
robot cleaner needs to be charged.
−The battery level indicator flashes while
recharging is in progress, showing the battery
level.
−If recharging is complete, the battery level
indicator turns on.
Inserting Batteries into the Remote
Control
1 Release the tab at the back of the remote
control to open the battery cover.
2 Insert two AAA batteries into the remote

remote control and close the cover.
Installing the Home Station
1 Remove the protective film attached to the
home station, the robot cleaner, and the
nozzle.
•If the protective film is not removed, the robot
cleaner may have difficulty finding the home
station or it may affect performance.
2 Position the home station on a hard, level floor
to prevent sliding during docking.

3 Insert the power plug into an outlet.
•When the home station is turned on, the LED
will light up.
4 Wrap the unwanted length of power cable
around the cord keeper to prevent the robot
cleaner wheels from rolling over the cable.
5 Place the home station against the wall so that
it does not move.
WARNING
•Wrap the power cable around the cord
keeper to prevent the robot cleaner wheels
from rolling over the cable. Failure to do so
could damage the robot cleaner or the power
cord, resulting in an electric shock or injury.

14 OPERATION
OPERATION
Using the Robot Cleaner
Before Starting
•The run time may decrease depending on
conditions of use or selected auxiliary functions.
•Collisions can occur during cleaning when the
sensor cannot detect the obstacle.
−Examples of obstacles that may be difficult to
detect include thin chair or table legs, glossy
or shiny furniture, and mirrors or glass.
•You may hear a tapping sound from the brushes
when the robot cleaner is cleaning laminate
floors or uneven floors.
•If manually placing the robot cleaner away from
the home station to start cleaning, choose an
area that is flat and free of obstacles.
•If the robot cleaner starts cleaning from the
home station, the robot cleaner can find the
home station faster when cleaning is completed.
•If the dust bin cover is open or the dust bin is
missing, the robot cleaner will stop cleaning and
announce a problem.
•If water gets inside the robot cleaner, do not
attempt to shake the water out of the robot
cleaner. Turn off the main power switch and
place the robot cleaner in a well-ventilated area
out of direct sunlight for at least 48 hours until
completely dry.
•The robot cleaner can cross over thresholds that
are up to 0.79 inches (20 mm) high depending
on the shape and material of the threshold.
•If the robot cleaner senses a moving object in its
path, such as a person or pet, it will request that
it move.
Preparing Cleaning Area
•Check the following items before use:
−Remove cables or long strings from the floor.
−Roll up or remove thin mats or thick area rugs.
Thin mats can get stuck in the nozzle, and the
robot cleaner will stop operating. The robot
cleaner may be unable to climb onto area rugs
with pile thicker than 0.79” (20 mm).
−Remove fragile objects and obstacles from the
floor.
−Remove foreign materials such as long
strings, metal objects, liquids, pet waste or
glass from the floor.
−Remove or protect furniture with narrow legs.
The robot cleaner may not detect narrow
objects and could bump into or push them.
−Close the doors of any room that you do not
want the robot cleaner to enter.
−Move shoes or other clutter at least 2 inches
(5 cm) away from thresholds. The robot
cleaner’s cliff sensor may become confused
and cause it to cross over a threshold it
cannot climb back over.
−Close any balcony doors as the robot
cleaner’s wheels may get stuck while
cleaning.
