1.1 Body
1. After use, turn the power off, and then take out the battery. Put the robot on a flat platform to prevent the
shading brush and central suction cup from damaging by pressing. Do not leave the robot in high
temperature, humidity, or sun exposure environment for a long time.
2. After each completion of work, put the dust cover in the brush socket, on the front left and back right of
the Kwun body, to prevent dust and water from entering the socket.
3. Check whether the screw is loose or there is abnormal sound.
4. Clean the surface with a soft cloth.
★Check carefully before and after each operation.

1.4 Track
1. When cleaning the BIPV project, no special maintenance is needed for the tracks, just keep the surface
clean, not seriously worn, and not cracked.
2. When working on components with 10-15°tilt angle, if the word "kwunphi" on the track is seriously worn, it
indicates that the surface becomes smooth and the friction is lost. Before working, use a 1000-grit sandpaper
or file to sand the track surface along the 45°angle to increase friction or replace the track with a new track.
3. When working on components with tilt angle of more than 15°, if the word "kwunphi" on the track is
severely worn, replace new tracks immediately (it is recommended to purchase a set of spare tracks just in
case).
★Check before and after each operation.

and soft towel.

the anti-fall sensor is not scratched by sharp objects, so as not to affect the normal use of the edge anti-fall

the body of the equipment (open the battery cover on the host to see the indicator label), do not discard for
daily use.
2. If the desiccant turns from orange to dark green, replace the desiccant.
3. Place inside the machine, do not eat.

2.1 Roller brush
1.If there are foreign objects such as rope and plastic bag on the component, during cleaning operation, the
rotation of the brush may wrap it on the brush, resulting in deformation of the brush. During daily cleaning
operation, we should observe whether the brush is wrapped by foreign objects such as rope, and if so, it
needs to be cleaned in time.
2. After daily cleaning, check whether the fixing screws at both ends of the brush body are loose. If yes,
tighten them in time.
3. The rolling brush should be placed upright to avoid irreversible deformation of the bristles under pressure.
★It is recommended to check before and after each job

3.1 Sprinkler head of water distributor
1. After a certain period of use, the water cube sprinkler on the rolling brush is easy to block the spray nozzle
due to water quality or stain pollution. After plugging, the spray nozzle should be cleaned and dredged in
time to prevent the blockage of the spray nozzle from affecting the cleaning effect.
★It is recommended to clean it once a week
