2. About Filter

■

Dust Bin Filter

It is recommended to clean the dust bin filter with HEPA 11 once a week. During the cleaning, clean thoroughly with cleaning brush and the cleaner. Never clean the filter with water. When it is washed with water, the cleaning performance will be degraded.

Make sure to install the dust bin filter (HEPA filter, sponge filter) to the dust bin after the cleaning.

If the dust bin or dust bin filter is not installed, dust may enter inside Roboking and cause disorder.

Cautions and Methods during the Usage

3. About Agitator

If foreign object is stuck in the agitator, it decreases the rotation speed and degrades the cleaning performance to cause disorder. Especially, after cleaning hair or hair of pets, make sure to clean the agitator. Clean periodically after 10 usages in ordinary homes.

If the agitator stops by foreign object during the cleaning, a voice alarm of “check foreign object in the agitator at the bottom” will sound. At this time, remove the foreign object stuck in the agitator before the usage.

Side agitator rotates synchronized with the bottom agitator. If the bottom agitator does not rotate, the side agitator will not rotate either.

How to Use Main Body Operation Buttons and Remote Controller

■ Turning ON/OFF the Power Button

The power switch at the left backside of the main body is connected between the battery and the Main circuit to function to supply or block the power. Also, it is connected between the recharging connector of the main body and the Main circuit to functions to supply or block the power of the recharging station.

When the main body power switch remains in ON state, the product can be turned on by pressing the button on the main body, and recharge is possible. If the power is not turned ON even if the power button on the

main body is pressed, or if power is not turned on even if the main body is connected to the recharging

station, check the status of the main power switch at the left backside of the main body.

※ When you turn on the main power button, do not turn it on while pressing the button at the top of the cleaning

robot. Button operation may be delayed.

Even if the main body power switch is turned on, Micom does not operate, so there is no change is the status indication window. To start Micom, press the start/stop button of the main body for 1 second after turning on the main body power switch. Then, Micom will start, LED of the screen display window will be turned on, and Booting will start. Booting time may be different for each model, and when the Booting is over, it converts to standby state with a melody.

In the standby state, if the start/stop button of the main body is pressed for 2 seconds or longer, the power will be turned off with the ending melody.

It is the state with the power off, but a small amount of electricity is used for button operation, so when it is left alone for long period of time, the battery may be consumed and power may not be turned on. When it is not used for long period of time, please store it with the power switch turned off.

Handling and Cautions

8.1 Disassembly: Never disassemble the battery pack. If the pack is damaged and short circuit is caused by conductive material inflow, overcurrent will flow and there is a risk of device damage or heat generation.

8.2 Handling: It may cause the falling out of soldered area or welded area, so be careful during the handling of the battery pack.

8.3 Short circuit: Be careful of the short circuit of the batter pack. If there is a short circuit in the batter pack, over-current will flow and there is a risk of device damage or heat generation. Do not expose it to heat.

8.4 Exposure to moist environment: Do not use the battery pack in a moist state. The current leakage by the moist of the insulating material inside the pack may cause degradation of the performance.

8.5 Recharging station: Use only the recharging station specified for this battery pack. Using other recharging station other the specification may cause heat generation, flame, or an explosion.

Safety Cautions and Verifications During the Repair

1. Make sure to convert the power to “Off” state when you check, disassemble, or repair

the cleaning robot. (Turn off the power button at the left backside of the main body.)

2. The circuits used in the cleaning robot are sensitive to static electricity, so repair in an

environment without static electricity. (Wear antistatic gloves and sleepers.)

3. During the electricity applied inspection of the circuit, do not have pin or coin contact

with the recharging part.

4. Make sure to use the designated parts for replacement parts during the repair.

5. Use appropriate tools for repair.

6. Make sure to check the damage of the power cable, etc. before the repair. If the sheath

is peeled or if there is a short circuit, make sure to firmly connect it and wrap it with insulation tape.

7. Check the parts with problems using the diagnosis program before and after the repair.

8. Check if the upper part and lower part of the main body are completely combined. (It

may cause degradation of the suction power or noise generation. Especially, check the handling of the lead line.)

9. Make sure to carry out the insulation test of the motor. (It is OK if it is 5MΩ or more

between the impeller cover of the motor and the power connector.)

Page 49

Check CLIFF sensor assembly direction and wire direction (blue is right side)

Assemble both side CLIFF to have the connector to be at the bottom, and the central CLIFF to be at the left side

Check PSD sensor assembly direction

Do not have wire passing over the guide

If wire is over the guide, it may be pressed by the main board during the assembly, and it may cause short circuit.

Assemble PCB after wire connection

First insert the connector, and assemble both sides PSD for the connector to be at the top

Be careful for IR wire not to be inserted

During the assembly of WINDOW LED in BASE, be careful not to have the rear IR wire pressed

Assemble after inserting all connectors before the assembly of front IR and ultrasonic.

Insert all the way

Assemble mop sensor wire on the guide so that it does not go over to motor fan side

If it is not properly inserted, the mop sensor function will not work properly, so check whether it works after the assembly

The rubber gasket shall not go out of the support

If the wire touches the fan, it causes abnormal noise, so firmly fix to the guide.

Assemble the marked part to face upward, and assemble rubber gasket inside the support
