FOR THE DISINFECTANT LIQUID
•The spray robot should be parked in a flat and solid place at normal temperature;
•Disinfectant belongs to external use and prohibited to be taken orally；keep it out of the reach
of Children.
•People who are allergic to chlorine should use it with caution. If there is allergic phenomenon,
stop using it immediately.
•When disinfectants are used for indoor-air disinfection, they should be carried out in the
absence of anyone.
•Incase of chemical reaction of disinfectants, it is recommended to clean the water tank with
clean water when changing different kinds of disinfectants.
•Cannot be used for metal objects disinfection. There is a certain bleaching on fabric.
•Users should wear latex gloves and do eye protection. If any touch happens on skin or eye,
clean it with clean water immediately. And if cause long-time discomfort, please seek for
medical advice immediately.
ROUTINE MAINTENANCE
When performing routine maintenance, please make sure that the robot is turned off, unplugged
or away from the charging pile! Otherwise, electric shock or serious failure may occur.
It is strictly prohibited to flush the robot and charging pile directly with tap water, which may lead
to the accumulation of water vapor or water inside the equipment and cause serious irreparable
failure.
CLEANING
1)Gently wipe the dirt inside the water tank and the ultrasonic sealing ring (the four black circles
seen after removing the water tank) with a brush and a wet cloth every week；
2）Regularly brush the surface of the driving wheel and universal wheel;
3）Use detergent and dust-free cloth to gently wipe the outer surface of the robot regularly；
4) Regularly contact after-sales for maintenance services such as lubrication, dust-cleaning
at the damping spring and universal wheel bearing;
5) Lidar sensor, as the expensive precision component in robot, should be wiped regularly with a
non-dust cloth. Do not wipe with force or other detergent, which may be easy to cause functional
damage
6) If the robot will not be used for a long time, store it in a dry and cool place.
CHECK THE SCREW IS LOOSE OR NOT
Shake the components gently on a regular basis to observe whether they are loose. If there is any
abnormal sound, please check the screws at the installation position of relevant components. All
the screws of the robot have undergone anti-loosening treatment. However, for the sake of safety,
please contact "BooCax After-sales" if any screw is found loose

2.Assembly
Step 1: Unpack and check materials
The packaging of this product consists of two boxes, with the larger box for the chassis and
charging pile, and the smaller box for the robot body. After unpacking, check the materials and
accessories against the Nos.1-8 in the figure below for any missing or damage.
Step 2: Install the sprayer
①Take out the chassis and place it
on the floor stably, make sure
that the lower charging mouth is
facing forward, pull out the two
connectors (Terminal 1: signal
wire, Terminal 2: power wire),
and visually find the six
positioning holes on the iron
plate →

②Turn the direction of knob on
the sprayer base forward, and
then pull out the two connectors
(Terminal 1, Terminal 2 as
shown) at the bottom to match
the male and female connectors
on the chassis. Six dowels are
aligned with the Six positioning
holes on the chassis (note that
the lower charging mouth of the
chassis is also facing forward) so
that it falls smoothly and snaps
into place →
③Remove the protective foam
from the water control valve on
the sprayer base to ensure that
the next stack of water tank is
not hindered →

Step 3: Dock the water tank and robot base cable
Lift the water tank stably, stack it
on top of the sprayer base. Relying
on the positioning steps that sink
around, it can be freely in place
from top to bottom under the
action of gravity →
Step 4: Install mist tube and one-way nozzle
Finally, remove the mist tube,
insert one end into the circular
outlet at the center of the water
tank, and then put the other end on
the top into a one-way nozzle for
connection (for tight
connection, it is recommended
to wrap it with waterproof tape
before putting it in) →

5. Preparation before use
5.1. Install the charging pile
The charging pile of the spray robot should be placed in a safe and tidy place. It should be on
the horizontal ground with its back against the flat wall (it is better to fix the charging pile to the
ground or wall). As shown in the following figure:
Schematic Diagram of Installation and Use of Charging Pile
①Place the back of the charging pile against the wall, and then turn the foot pads at the
bottom to adjust the charging pile.
②Connect the power cord, adapter, and charging pile as shown above, and finally connect the
end of the power cord to the 110V / 220V AC socket to formally complete the boot preparation.

5.2. Clean up barriers
1) Before using the spray robot, remove the barriers in the aisle to avoid affecting the working
and charging of the robot;
The minimum walking width of the robot is 750mm
2) Make sure that there is no vertical step over 15mm in the spraying area, and no objects (books,
boards, stones, etc.) over 15m m in height on the working path;
The surmounting height of the robot is 15mm
3) Make sure that there is no large slope on site:
The maximum gradeability of the robot is 8°.
5.3. QR code deployment
In order to enhance the positioning accuracy of the robot, we designed a QR code scheme to
ensure that the robot's long-term running position is not lost. The QR code is generally used where
the robot positioning is prone to deviation, for example, the two ends of a long corridor, in which
case, a QR code can be pasted at a distance of 10m from the two ends to assist positioning.
10mm

BKS-ST-220A_Product Manual
BooCax 16 / 30 boocax.com
1) Precautions for QR code pasting
•Avoid deploying at a place with strong light, so as not to affect the camera to capture the
QR code image;
•The QR code should be pasted at the same level as the camera;
•Paste the QR code in the direction as the arrow;
•If the QR code is damaged, replace it in time.
2) The example is shown below
3) Precautions for saving QR code
•No duplicate QR code boards can appear in the same environment;
•When mapping, the robot stops at the QR code board for 1-2 seconds to ensure that the
QR code is saved（Voice prompt will be given for successful identification）；
•The QR code of the charging pile should be identified by the camera in front of the robot,
and the QR code of a corridor can be identified by the cameras on the left and right;
•When incrementally mapping, it is necessary to ensure that the robot's positioning is
accurate before identifying and saving the QR code.

5.6. Build the spraying map
1) Preparation before building the map
·Push the robot 0.5-1m in front of the charging pile
·Robot power >50%
2) Start building the map
Click "Deploy" on the homepage of App to show the "Build Map" button. Click the button to build
a two-dimensional spraying map, as shown in the following figure (Push the robot by hand to build
the map):
Legends:
•White radius—the range scanned by the laser;
•Black thick line—the scanned obstacles (special objects such as transparent glass may not be
identified);
•Gray area: Area that has not been scanned.
After the map is built, the robot can locate and navigate on the new map.
⚠Attention:
①When mapping by hand, push the robot forward slowly in the scene from the charging pile
as the starting point, and finally return to the charging pile to form a large circle;
