HOW TO TURN THE HOM-BOT POWER SUPPLY ON & OFF

Turning on the main power supply

To turn the power supply on, turn the HOM-BOT upside down
on a smooth/soft surface and check whether the main power
supply switch is turned on.

If the main power supply switch is turned off, turn on the
switch.

※

When turning on the power switch, do not press the button
located at the upper section of the HOM-BOT. Operation of
the button can be delayed.

※ Turn off the power switch if the HOM-BOT will not be used

for a long period of time, in order to protect the battery.

※ The power switch cover is used for protecting the switch

from the dust. Always keep the cover attached.

Turning on from Stand By mode.

When the HOM-BOT is not at the Home Station, and is in
the Stand by mode, press the ‘START/STOP’ button for
more than 1 second. The HOM-BOT will be turned on and
a melody will be sounded.

※

If the power is turned on while the HOM-BOT is not at
the Home Station, and nothing is done for ten minutes,
the unit will turn off and enter Standby mode to reduce
battery consumption.

Turning off the unit

Press the START/STOP button for two seconds while the
HOM-BOT is turned on. A melody will sound when the
power is turned off.

Tip

• The power can be turned off due to the static electricity during

the operation.

- If the power is turned off, turn off the main power switch and
then turn it back on.

• If the power cannot be turned on, do the following.

- Turn on the power switch and wait for more than 3 seconds.

- Press the ‘START/STOP’ button when the power switch is
turned on.

- If the power is not turned on or if there is no display but only
the “Ting” sound, put the HOM-BOT on the home station.

- If there is no change even when HOM-BOT is attached to the
home station, press the reset switch located on the rear side
of the home station while the HOM-BOT is attached on the
home station.

14

HOW TO START AND STOP CLEANING

Using the buttons on the HOM-BOT

After the HOM-BOT is turned on, press the START/STOP button to
begin cleaning. A melody will sound and cleaning will begin.

Press the START/STOP button during the cleaning cycle to stop cleaning.

※ When the 'START/STOP' button is pressed while the power supply is

turned off, the unit will not turn on.

Using the remote control

After the HOM-BOT is turned on, press the START button on the re­mote control. A melody will sound and cleaning will begin.

Press the STOP button during the cleaning cycle to stop cleaning.

※ The Hom-Bot cannot be turned on from Standby mode using the

remote control. To turn on the unit, press the 'START/STOP' button

on the body, and then use the remote control to operate.

※ When the START button on the main unit or remote control is pressed, HOM-BOT will start cleaning in

‘Spatial expansion’ mode.

※ During cleaning, collisions can happen when the sensor cannot detect objects because of their shape.

When this happens, the internal impact detecting sensor will activate and engage a backward motion.

※ If the HOM-BOT is set to start cleaning at a location away from the home station, put the device on a flat

floor in order to prevent a malfunction of the obstacle detecting sensor. In addition, start cleaning from a
location where there are no obstacles such as curtains or walls within 11.8in. of the HOM-BOT.

Tip

For best results:

• Briefly scan the area to be cleaned for big and small objects that may cause difficulty for the

HOM-BOT.

• If cleaning is started when the HOM-BOT is at the home station, the device can rapidly be re-

turned to the home station as the current home position has been accurately read.

15

HOW TO CHARGE THE BATTERY

Automatic charging

The HOM-BOT returns to the home station at the end of a cleaning cycle
or when its battery is running low.

※ In the event that the unit returns to the Home Station due to a low

battery, cleaning will be started, after the charging, from the near­est place of the area which has not been cleaned before.

※

If the HOM-BOT is unable to dock to the home station on its first at­tempt, it will try again until it docks successfully.

※ When the HOM-BOT has cleaned all areas that it can clean, it will

return to the home station even when the battery level is not low.

Manual charging

If using the HOM-BOT for the first time or to charge the battery by interrupting the cleaning, you can
manually charge the battery.

Method 1. Attach the HOM-BOT to the home station by matching

up the two arrows on the HOM-BOT and the home sta­tion. A melody will sound and charging will begin.

※ When the HOM-BOT is attached to the home station,

and a “TING” sound is generated repeatedly, please check
and ensure that the power supply on the underside of the
HOM-BOT is in the ON position.

Method 2. When the HOMING button of the remote control or the

HOM-BOT is pressed, charging will start automatically
when the HOM-BOT has returned to the Home Station.

※ When the unit is turned on from Standby mode and is within 4in of the home station, the unit will auto-

matically dock itself to the station and charging will begin.

Tip

Take the following precautions when using the home station:

• If foreign material is caught in the charging terminal, charging may not proceed smoothly.
Wipe the terminal from time to time with a dry cloth after the power plug is disconnected.

• To prevent electric shock, do not touch the charging terminal with any metallic objects.

• To avoid fire or electric shock, never disassemble or modify the home station.

MOP CLEANING (Mop attachment sold separately)

By attaching the ultra microfiber mop, you can ef­fectively use the HOM-BOT to remove dust.

When the mop plate is attached, the HOM-BOT will
not climb on to carpets or over thresholds, in order to
prevent transferring dirt from the mop.

For mop cleaning, mount the mop and mop plate to the HOM-BOT according to the following instructions:

1. Attach the ultra microfiber mop to the Velcro
of the mop plate as shown in the figure.

※ To prevent the HOM-BOT from malfunction-

ing, do not cover the attaching guide with
the mop.

the home station for charging the battery. In order to maintain the performance
of the HOM-BOT, regularly clean the sensors and charging terminal as follows:

1. Lay a smooth cloth on the oor, overturn the HOM-BOT and put it on the
cloth.

2.

Turn off the power switch on the bottom of the HOM-BOT. Injury can be
caused by the activation of the HOM-BOT if the main power is not turned off.
