GETTING STARTED
Charging The Battery
IMPORTANT NOTE: Fully charge the pool vacuum (about 6 hrs) before using
it for the first time.
WARNING!
Use only the original external adaptor and charging plug provided.
Make sure the pool vacuum 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 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.
1. Place the unit on a flat surface. Set the pool vacuum to Power Off/
Charging Mode by turning the switching knob anticlockwise until it clicks
and completely exposes the charging port.
2. Align and attach the charging plug to the charging port. WARNING! Be
sure not to invert the charging plug and ensure both the charging plug and
charging port are clean and dry before charging them. TIPS: Use cotton
bud to dry the charging port and pins. Plug the charging cable of the
external adaptor into the charging plug.

11
3. Connect the external adaptor to the power source. The indicator light on
the external adaptor will turn red when the vacuum is charging and green
when it is fully charged. Charge it for 5-6 hours for best performance.
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 charging plug.
Detach the charging plug from the main unit. WARNING! Never leave the
charging plug while the pool vacuum is in the water.
Normally the pool vacuum is designed to operate for up to 75 minutes on a full charge.
Note: Empty the filter bag regularly. Excessive debris increases the burden to the motor
and may shorten the operating time.
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 pool vacuum 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 pool vacuum rest for around 30 to 40 minutes before charging it again.

Pool Preparation
- 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 pool vacuum.
- If you are using a saltwater pool, make sure all salt are dissolved before placing the pool
vacuum into the water.
OPERATION
1) Bring your pool vacuum to the side of your pool. Turn the switching knob clockwise
until it clicks to expose the water sensors. The light at the top will turn blue.
Immerse the pool vacuum into water, the light turns immediately to green and the
impeller will start to turn after 4-5 seconds.
Light Color
Blue Power On
(ready for operation)
Blue – Flash Battery level is running low
Green In operation
Green -Flash Battery level is running low.
Green light Off Battery depleted
(need to be recharged)
Red Impeller stops
(impeller clogged).

14
To effectively vacuum up debris, ensure the pool vacuum is laid flat on the pool floor as
you steer it back and forth in regular motion over debris patches for collection. Debris is
collected from the front, side and back to fill up the filter bag.
Excess dirt and debris in the pool could clog the impeller, which would automatically stop
to protect the motor, and the indicator light would turn red. Remove the vacuum from the
pool and turn it off prior to unclogging and emptying the filter bag if it is full. To resume
operation, turn the switching knob anticlockwise until Power Off is selected, then turn it
clockwise to select Power On.
2) To retrieve the pool vacuum, bring it poolside and flip it upside down before lifting. This
is done to prevent debris from scattering back into the pool (especially if you are using
the fine filter bag) and avoid bending the pole in the process.
Once the pool vacuum is out of the water, the impeller will cease to spin within 2-3 seconds.
The LED light will turn blue. When battery level is running low, blue light will flash.
3) Rinse the pool vacuum with fresh water after every use. DO NOT use any aggressive
detergent.
4) Dry the charging port and pins thoroughly (TIPS: Use cotton bud to dry them).
Vacuuming the Sunken Compartment of an Automatic Slatted Cover
WARNING! Pay attention to all safety warnings in the manual of your
automatic slatted cover concerning this cleaning operation beforehand.
- The minimum distance required for the immersion of the vacuum into the sunken
compartment is 30cm (12in )

15
- Remove the duckboard and unroll the pool slat according to instructions from your
pool cover manual.
- Detach one extension of the vacuum cleaner before immersing it into the pool.
- Attach a telescopic pole (not provided) to the pool vacuum handle as instructed in the
