HOW THE ROBOT WORKS
The robot has a water-propelling nozzle at the bottom of the swivel head. Water is first sucked
in through the suction mouth at the bottom of the robot, which then goes through the filter and is
discharged 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, its side flap sways and its swivel
head turns 180o, 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 5-6 hrs) before using it for the first time.
WARNING!
Use only the original external adaptor and charging base provided.
Make sure the robot and the charging port are clean and dry before set-up.
Make sure the robot is off by sliding the switch to the OFF position prior to charging.
1. Place the unit on a flat surface. Slide the switch to the OFF position.
OFF
ON
2. Place the unit on a flat surface. Plug the socket of the charging base into the built-in charging
pins once they are aligned. WARNING! Be sure not to invert the charging base. Plug the
charging cable of the external adaptor
3. Connect the external adaptor to the power source. Once the robot begins charging, the
indicator light on the external adaptor will turn red.
The indicator light on the external adaptor will turn green when the robot is charged. Charge
it for 5-6 hours for best performance.
RED light - Charging
GREEN light - Charged
Immediately disconnect the external adaptor from the power source if you detect any of the
following:
-Offensive or unusual odor

-Deformation, cracks, leaks
-Smoke
4. When charging is complete, disconnect the external adaptor from the power source and
unplug the charging cable from the charging base.
IMPORTANT: Make sure to unplug the charging base from the swivel head after charging is
complete.
Normally the robot can operate up to 120 minutes on a full charge.
NOTE: Clean the debris compartment regularly. Excessive debris inside the compartment
increases the burden to motor operation and shortens the operating duration as a result.
NOTE: Rechargeable lithium-ion battery is classified 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 and replacement of swivel head.
NOTE: Let the robot rest for around 30 to 40 minutes before charging it again.
Set-Up Before Use
Clip-on Rake/ Brush Assembly
TIPS: Press on the two hook ends to remove the rake/brush
IMPORTANT NOTE: Remove rake/brush after use. Otherwise, they may deform due to
constant compression, and could interrupt robot movement as a result.

Adjustment of Trajectory: Tube setting
Set the tubes A & B according to below instruction.
1)For pools where the shortest length is 3 meters or above
Turn the tube A to position “0” or “1”
Set tube Bin position
Tips: To achieve a steeper curve in trajectory, adjust the tube A to position “2”.
2) For pools where the shortest length is below 3 meters
Set the tube A to position “2”
Set tube Bin position

11
NOTE: In case the robot is moving in circle or cannot cover the entire pool, set the tube B to
position “ ” as below:
Note: You will hear a “click” sound everytime you adjust the fin.
Bumper
Use of the bumper is optional and can be applied in the following situation:
If the robot tends to follow the perimeter of a round pool, clipping a bumper on each side of
the robot will eliminate this pattern.
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 qualified professional.
- If the liner is brittle, damaged or wrinkled, contact a qualified professional to perform the
necessary repairs or perform a liner replacement prior to using the robot.
- Remove any pool ladder, surface skimmer, and other floating objects from the pool as
they may obstruct the movement of the robot’s float and, consequently, the movement of the
robot also.
- If you are using a saltwater pool, make sure all salt are dissolved before placing the robot
into the water.
IMPORTANT NOTE: Turn off the filtration system (as instructed in your filtration manual)
at least 15 minutes prior to deploying the robot.

12
OPERATION

3. Immerse the robot into the water and operation will automatically begin as water level covers
the sensors at the top of the swivel head. Let the robot sink to the pool floor and observe the
cleaner's first forward and reversed movements across the pool bottom. If the robot runs
along the pool wall instead of perpendicular to it, reposition it to make sure that its front/back
faces the pool wall.
IMPORTANT NOTE: The swivel head may rotate repeatedly for a few minutes once the
robot sinks to the pool bottom. This phenomenon will stop once the air trapped inside the
robot is gradually discharged and the robot will begin to move regularly.

13
Power indicator lights:
As the robot moves around the pool and collects debris, battery levels will gradually drop and
the indicator lights will follow suit.
4 lights ON
Up to 120 minutes left
Last light blinks
Only 10 minutes of usage remains
once the last light starts blinking.
NOTE:
-Refrain from making any physical contact with both water sensors.
4. To retrieve the robot from the pool, attach the hook to a telescopic pole (not provided) and
use it to retrieve the float, if you are unable to retrieve with your hands.
As the robot reaches the water surface, locate the end with the red triangle (as shown in the
image below) and grab onto the robot via the grip (Note: holding the other end of the robot will
lead to escape of debris through the drainage outlet) to lift the cleaner to drain the water out of
the robot.
5. Slide the power switch OFF. Rinse the robot with fresh water after every use. DO NOT use
any detergent.
NOTE: To ensure the most efficient cleaning, when your pool is quite dirty, it is recommended to
empty the debris compartment after the first 30min of operation, or whenever the robot’s
movement has slowed down noticeably. Then return the robot (with an emptied debris
compartment) to the pool, and let it run through the remaining of its cycle.
