4. Safety Instructions
Requirements for the Operator
1. The operator must be trained and provided with specialized protective
clothing.
Operating Environment
1. While using the robot, keep it away from people, plants, and animals
for protection against disinfectant spray.
2. Only use the wheeled robot in indoor environments with flat grounds
(smooth grounds, gradient < 10°, and obstacle height ≤ 1 cm); do not
use it in outdoor environments, such as open balconies, or rugged
grounds, such as stairs.
3. Do not use the robot at temperatures above 50°C or below 0°C or on
wet or sticky grounds.
4. Before using the robot, put away wires and cables on the ground in the
operating environment to prevent them from being dragged by the robot
and remove any sharp objects, such as decoration waste, glass, and nails,
on the ground to prevent damage to the robot chassis.
5. Do not use the robot in environments with combustible gases and
other hazards.

9
Operation Requirements
1. No personnel is allowed in the area in which the robot is operating.
2. The entire robot disinfection process must be monitored by an
operator to ensure timely manual intervention.
3. Manually control the robot with the spray disinfection function
disabled in public areas if the robot is not executing a disinfection task.
4. Unauthorized replacement of any component is strictly prohibited. If
replacement is necessary, do it with the approval and under the guidance
of FJD.
Check Before Use
1. Ensure that the robot has more than 30% battery power and sufficient
disinfectant.
2. Ensure that relevant parameters in the tablet terminal have been
calibrated before automatic operation.
3. Ensure that the Wi-Fi and network communications are normal. In the
event of any abnormality, fix it before using the robot.
4. Before starting the robot, check whether the safety devices, such as the
sensors and emergency stop switch, are normal.

10
Battery and Charging
1. Do not use any third-party batteries, adapters, or charging piles.
2. Do not remove, repair, or retrofit the battery or charging pile without
permission.
3. Do not wipe or clean the charging contacts of the charging pile with a
wet cloth or wet hands.
4. Do not discard battery scraps casually. Instead, hand them to
professional recycling agencies for disposal.
5. Do not place the charging pile near any heat source, such as heating
radiators.
6. If the robot will not be used for a long time, empty the disinfectant
tank, fully charge and power it off, and keep it in a cool, dry environment.
To prevent battery damage, charge the robot at least once a month.
7. To charge the robot, pay attention to its power supply requirements.
For the charging pile, the input voltage is 100–240 V AC and the output
voltage/current is 54.6 V/5 A DC.
8. Touch of the circuit connector is strictly prohibited while the robot is
being charged.
9. Directly rinsing the robot and charging pile with tap water is strictly
prohibited, because it may cause moisture accumulation or water entry
inside the device and serious irreparable faults.

11
Spray Disinfection Robot
1. To prevent damage to the device, only trained professionals are
allowed to disassemble the disinfection device.
2. Do not clean the robot or add disinfectant when the robot is turned
on.
3. Be careful not to splash disinfectant on other parts of the robot when
adding it.
4. Before changing the disinfectant, clean the disinfectant tank with clean
water to avoid chemical reactions between different disinfectants.
5. While operating, the robot must be kept at least 10 m away from
people and animals for protection against disinfectant.
6. Stay away from the robot to prevent personal harm due to inhalation
of disinfectant.
7. If the robot cannot be powered off remotely, wear protective clothing
and goggles to avoid inhalation of disinfectant before going to the
operating site to manually power off the robot.
8. The proper temperature range for robot operation is 0–50°C.
Temperatures out of the range will directly affect robot operation.
9. The disinfectant can be hydrogen peroxide or hypochlorous acid, and
adding additives not applicable to this product into the disinfectant tank
is strictly prohibited. Do not use aromatic oils.

12
Note: For details about the safety and use of the selected
disinfectant, refer to the operation guide provided by the
disinfectant manufacturer.
Others
1. Do not remove the housing of the robot by yourself to avoid affecting
the warranty service.
2. Device damage resulting from force majeure (lightning strike, high
voltage, collision, or the like) is not within the warranty scope.
3. Connect the device as instructed in the manual. Pull or plug cables
gently by holding the end of the plug. Do not drag the cables by force to
prevent cable breakage.

5. Application Scenarios of Disinfection Robot
Disinfection robot
No.
Scenario
Application
Requirement
Precautions
1
The robot can only
travel on flat ground
without stairs.
The robot is designed to travel on
flat ground, with a maximum
gradient of 10° and a maximum
obstacle height of 10 mm. It cannot
travel up or down stairs. Ensure that
the ground is flat.
2
The width of the
disinfection path must
be 1 m or wider.
The robot is 0.5 m in width, and its
ultrasonic sensor and LiDAR have a
detection width of 0.8 m. If the path
is narrower than 0.8 m, the robot
may determine that there are
obstacles ahead.
3
Ensure that no people
or animals are in the
operation area.
1. The robot has an effective spray
disinfection radius of 2 m.
2. Use the recommended
disinfectants to avoid harms to
animals and plants.

14
4
The robot can detect
surroundings within 40
m around it and
disinfect an area of no
larger than 10,000 ㎡
at a time.
1. From the start point, move the
robot straight forward, backward,
left, and right for no more than 40
m to create the map. For areas out
of that range, create more maps.
2. The map must be created from
the center. The robot can disinfect a
maximum area of 10,000 ㎡at a
time. Create multiple maps if the
disinfection area exceeds 10,000
㎡.

6. Robot Introduction (Understanding of the Robot)
⚫The FJD Spray Disinfection Robot operates indoors, suitable for
public indoor spaces such as hospitals, hotels, offices, supermarkets,
restaurants, Internet cafes, and KTVs.
⚫With LiDAR and the all-around smart sensors, the FJD Spray
Disinfection Robot is capable of automatic positioning, navigation,
and obstacle avoidance. It can automatically travel indoors or be
manually controlled via FJD’s robot control app with a tablet.
⚫The FJD Spray Disinfection Robot’s disinfection system is capable of
disinfectant atomization.

7. Main Structure of the Robot
Figure 1 shows the main structure of the FJD Spray Disinfection Robot. Its
chassis has two driving wheels and four driven wheels. With LiDAR, the
robot realizes automatic positioning; and by integrating multiple sensors,
such as the LiDAR, the ultrasonic sensor, the depth vision sensor, and the
safety edge sensor, it can also avoid obstacles automatically.

Add Disinfectant
1. Wear protection gloves and goggles to prevent personal harm from
disinfectant.
2. Power off the robot.
3. Prepare the disinfectant in the container.
4. Remove the disinfectant tank cover by lifting the handle on the side.
5. Slowly pour the disinfectant into the disinfectant tank with a
measuring cup. The maximum capacity of the disinfectant tank is 16 L.
Ensure that the liquid level is between the maximum level and the
minimum level, to prevent disinfectant overflow, which may cause short
circuits of other devices.
