HOW THE ROBOT WORKS
The robot has a water-propelling nozzles at the top of the robot. Water is rst sucked in through
the suction mouth at the bottom of the robot, which then goes through the lter and is dis-
charged via the propelling nozzle. Water jetting from the nozzle propels the robot forward. Once
the robot stops against an obstacle such as the pool wall, it changes to jet the water on opposite
nozzle, allowing the robot to move in the opposite direction. The robot moves in a generally
straight pattern in one direction and in an arc pattern in the other direction. The robot vacuums
the pool bottom as it moves, collecting debris in its compartment.
GETTING STARTED
Charging The Battery
IMPORTANT NOTE: Fully charge the robot ( about 6 hrs ) before using it for the
rst time.
WARNING!
- Use only the original external adaptor and charging connector provided.
- Make sure the robot and the charging port are clean and dry before set-up
and charging.
( TIPS: Use a cotton bud to dry the charging port and charging pads inside.)
- The charging pads are waterproof. However, remnants of water in the port
and around the pads could result in natural occurrence of stains ( a byproduct
of chemical reaction between water and electric currents ). Otherwise, the
stains can be removed by light scrubbing with a cotton bud soaked with juice
of lemon or vinegar.
1. Place the unit on a at surface. Slide the switch to the OFF position.

2. Align and insert the charging connector to the charging port. WARNING!
Ensure both the charging connector and charging port are clean and dry before
charging them. TIP: Use a cotton bud to dry the charging port and pads.
3. Connect the external adaptor to the power source. The indicator lights on the
the robot turns red and ash once the charging begins. The indicator lights
turn green when the robot is charged.
· Immediately disconnect the external adaptor from the power source if you
detect any of the following:
- Oensive or unusual odor
- Excessive heat
- Deformation, cracks, leaks
- Smoke
4. When charging is complete, disconnect the external
adaptor from the power source and unplug the
charging connector from the unit.
Normally the robot can operate up to 75 minutes on a full charge.
NOTE: Clean the debris compartment regularly. Excessive debris inside the
debris compartment increases the burden to the motor operation and shortens
the operating duration as a result.
NOTE: Rechargeable lithium-ion battery is classied as a consumable item. It
has a limited life and will gradually lose its capacity to hold a charge. Therefore,
the running time of the robot will gradually reduce after repeated charging and
discharging throughout its product life.
Once the lifespan of the battery reaches its end, refer to section “BATTERY
DISPOSAL” for instructions regarding battery disposal.
NOTE: Let the robot rest for around 30 to 40 minutes before charging it again.

Set-Up Before Use
Adjustment of Trajectory
Locking Pin
The trajectory of the robot is dependent on the
position of the pin that xes the axle to a certain
angle.
Recommended settings:
NOTE: Wheel axle should be positioned
above the locking pin.
Pool Preparation
- If there are stones, roots or metal corrosion in contact with the underside of the liner, discard them prior to using the
robot. If necessary, seek assistance from a qualied professional.
- If the liner is brittle, damaged or wrinkled, contact a qualied professional to perform the necessary repairs or perform
a liner replacement prior to using the robot.
- Remove any pool ladder from the pool as it may obstruct the movement of the robot.
- If you are using a saltwater pool, make sure all salt are dissolved before placing the robot into the water.
Pin location Pool size
For pools where the shortest
length is 3 meters or above.
If the robot does not cover the
entire pool with either pin
position 1 or 3, try below setting.
If the situation persists, deploy
the robot from a dierent location.
For pools where the shortest
length is 3 meters or below.

EMPTYING THE DEBRIS COMPARTMENT
WARNING! Using the robot without its lter cover in place will VOID
your warranty.
In order to maximize the cleaning eciency, clean the debris compartment and
the lter cover before and after each use.
CAUTION! Before cleaning the debris compartment, make sure the robot is OFF.
1. Place the cleaner on a at and sturdy surface. Pry open the side clips to release the top cover from the base. Remove the
top cover from the base to expose the lter cover.
2. Detach the lter cover and remove the debris from the compartment. It is recommended to clean the lter cover net
with splashing water. If brushing is deemed necessary, use only a soft brush to clean it carefully and gently to avoid
damages.
3. After cleaning, align and put the lter cover back to the base.

4. Align the top cover to the base as shown.
Note: There is only one direction in alignment.
5. Press on all side clips until they are secured to the base. A“click” sound will conrm the top cover is secured to the base.
TIPS: Before redeploying the robot to the pool, ensure the top cover is secured to the base.

MAINTENANCE & STORAGE
NOTE:
1) Be sure to clean and dry the areas around the charging port after every use to avoid the forming of stains (
byproduct of a natural chemical reaction between electric current and water ). Otherwise, the stains can be
removed by light scrubbing with a cotton bud soaked with juice of lemon or vinegar.
2) Battery discharges on its own during storage. Make sure to fully charge the robot before storage.
3) You must recharge the battery at least once every three months when it is not in use.
· Unplug the external adaptor from the socket and the charging connector from the robot.
· Detach accessories from the robot. If necessary, rinse the robot and accessories with fresh water. DO NOT use
detergent.
· Be sure to drain the water from the robot before storage.
· Use a damp cloth to clean and dry the robot and its accessories.
· Store them in a well-ventilated area away from sunlight, heat, ignition sources, pool chemicals and from
children. Ambient temperature for storage should be 10˚C – 25˚C ( 50˚F – 77˚F ). NOTE: A higher storage
temperature may reduce the battery life.
WARNING! Under no circumstances should you disassemble the robot to
replace its internal components by yourself. Doing so would void the warranty,
expose yourself to potential hazards, and possibly damage the device and other
properties.
CAUTION!
· Excessive heat can damage the battery and reduce the lifespan of your robot as a result.
· Consult your dealer regarding battery replacement if the following happens:
- Battery does not charge fully.
- Battery operation time is noticeably reduced. Observe and record the run times of the rst few operations (on
a full charge). Use these run times as a reference point for comparison with run times in the future.
· The battery must be removed from the robot before it is scrapped.
· The robot must be disconnected from the supply mains when the battery is being removed.
· The battery is to be disposed safely in accordance with local ordinances or regulations.
NOTE: Incorrect maintenance may reduce the battery life and aect its capacity as a result.
BATTERY DISPOSAL ( To be carried out by an authorized technician )
Your robot is equipped with a maintenance - free rechargeable lithium-ion battery pack, which must be disposed
of properly. Recycling is required; please contact your local authority for more information.
WARNING! Never attempt to disassemble a battery pack.
· Remove all personal items such as rings, bracelets, necklaces and watches
when the battery pack is unwired from the robot.
• A battery can produce a short circuit current high enough to weld a ring ( or
similar item ) to metal, causing a severe burn in the process.
• Wear complete eye protection, gloves and protective clothing when the
battery pack is being removed.
• Avoid touching the wires altogether and avoid contact between them and
any metal items, which could cause sparking and/or short circuit the battery.
• Never smoke or allow a spark or ame in the vicinity of the battery or the
robot.
• Do not expose the battery to re or intense heat as this may result in an
explosion.
CAUTION!
If a battery leak occurs, avoid any contact with the leaking uids and place the damaged battery in a plastic bag.
- If leaking uids come in contact with skin and clothing, wash immediately with plenty of soap and water.
- If leaking uids come in contact with eyes, do not rub eyes, immediately ush eyes with cool running water for
at least 15 minutes and do not rub them. Seek medical attention as soon as possible.
