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 180˚, 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 first time.

WARNING!

• Use only the original external adaptor and charging cable provided.

• Make sure the robot and the charging port are clean and dry before set-up and charging.
  ( TIPS: Pry open the protective cover and use a cotton bud to dry the charging port and charging pins )

• The charging pins are waterproof. However, remnants of water in the port and around the pins 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.

• 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.
   

2. Plug the charging cable of the external adaptor into the charging cable. Pry open the protective cap. Align and insert the plug of the charging cable into the charging port at the top of the unit.
   WARNING! Be sure not to invert the charging cable and ensure both the charging cable and charging port are clean and dry before charging them.
   TIPS: Use cotton bud to dry the charging port and pins.
   

3. Connect the external adaptor to the power source. The indicator light on the external adaptor turns red once the charging begins. The indicator light on the external adaptor will turn green when the robot is charged.
   

   • Immediately disconnect the external adaptor from the power source if you detect any of the following:
   • Offensive 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 cable from the unit and external adaptor.

Normally the robot can operate up to 45 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 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

Adjustment of Trajectory

Locking Pin
The trajectory of the robot is dependent on the position of the pin that fixes the axle to a certain angle. Alter only the position of the pin on left.
Recommended settings:

NOTE: Wheel axle should be positioned above the locking pin.

)
| For pools where the shortest length is 2 meters or below.

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.

OPERATION

WARNING!

• Make sure the robot is off.
• Ensure the charging cable is detached and the charging port is plugged with the protective cap before the robot is deployed.

1. Bring the robot to the side of your pool.
   NOTE: Only deploy the robot from the pool side (not the pool corner) and ensure it is facing outwards as you do so. Unwrap the retrieval cord from the float ( note: there are side notches at the top and bottom of the stem, as well as a narrow slot at the bottom ).
   The correct length of the rope should be equivalent to the distance between the top of the robot and the water level.
   NOTE: Excess length may kink the rope and affect performance as a result.
   First, align and attach the retrieval cord to the side notches at the top as you wrap the cord around the stem ( step 1 & 2 ).
   Keep wrapping the cord around the top half of the stem until it reaches the required length ( step 3 ). Pull the cord down to the bottom slot and tuck it in ( step 4 ).
   

2. With the robot switched off, submerge it in the pool and gently shake it a few times to facilitate discharge of air. Excess air trapped in the body could result in erratic behavior of the swivel head ( i.e. spinning repeatedly in the pool for a few minutes ).
   

3. Slide the power switch to “ON” ( while the robot is still submerged ) – the indicator light will turn on and activate the motor automatically ( water level covering the sensors at the top of the swivel head ). Let the robot sink to the pool floor and observe its first forward and reversed movements across the pool bottom. If it runs along the pool wall instead of perpendicularly, retrieve it and redeploy it while making sure its front/back is facing the pool wall
   Power indicator light starts to blink when 5 – 10 minutes of usage remains.
   Power indicator light:

   • No light – Power off / no power

   • Light – Power on

   • Blinking light – Battery power will be exhausted within 5 – 10 minutes.
     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.
   ( for EU & US only )
   ( for Australia / New Zealand only )
   
   As soon as the robot reaches the water surface, locate the grip that is underneath the base and indicated with the hand symbol ( see diagram below ) to facilitate retrieval from the pool. Make sure to always grip the robot from this end to prevent debris from falling back into the pool during retrieval.
   

5. Slide the power switch OFF. Rinse the robot with fresh water after every use. DO NOT use any detergent.

6. Dry the charging port and pins thoroughly ( TIPS: Use cotton bud to dry them ).

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.

EMPTYING THE DEBRIS COMPARTMENT

WARNING! Using the robot without its filter cover in place will VOID your warranty.
In order to maximize the cleaning efficiency, clean the debris compartment and the filter cover before and after each use.

CAUTION! Before cleaning the debris compartment, make sure the robot is OFF.

1. Place the cleaner on a flat and sturdy surface. Pry open the side clips simultaneously to release the top cover from the base. Pry open either side clip first before moving onto the other one if the aforementioned method proves to be too challenging. Slide out the top cover from the base to expose the filter cover.
   

2. Detach the filter cover and remove the debris from the compartment. It is recommended to clean the filter 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, make sure that the filter cover is in place and reverse the steps above to re – align the top cover to the base.
   Press on both sides of the top cover until the side clips are secured to the base. A “click” sound will confirm the top cover is secured to the base.
   

TIPS: Before redeploying the robot to the pool, hold onto the wings on the body top cover to sway the robot slightly, to ensure the top cover is secured to the base.

CAUTION!

• Replace a damaged filter cover immediately with a new one before the next operation.
• Replace a damaged float immediately with a new one before the next operation.

Float Replacement
Use a screwdriver ( not provided ) to unscrew the 4 screws at on the top cover of the swivel head. Untie the knot on the string to remove the damaged float. Ensure the round switch is in place before sliding the string of the new float through the top cover and tying a knot to keep it in place, and then re-install the top cover with screws.

• Replace a damaged flap immediately with a new one before the next operation.
