1. Place the unit on a at surface. Make sure the pool vacuum is o
by turning the power ON/OFF switch to the OFF position prior to
charging.
2. Align and slide the hook of the charging base onto the side notch at
the bottom of the main body until it stops. Make sure their contact
plates are properly in contact.
GETTING STARTED
Charging The Battery
IMPORTANT NOTE: Fully charge the pool vacuum (about 6 hrs) before
using it for the rst time.
WARNING!
- Use only the original external adaptor and charging base provided.
- Make sure the pool vacuum and the charging contact plates are
clean and dry before set-up and charging. (TIPS: Use a cotton bud to
dry the charging contact plates)
- Charging must be done indoors, in a well-ventilated area away
from sunlight, children, heat, ignition sources, and with an ambient
temperature between 5˚C (41˚F) and 35˚C (95˚F).
- Never use the external adaptor and charging base if any damage is
detected.
- The charging contact plates are waterproof. However, remnants of
water on the contact plates 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 that the pool vacuum is turned o prior to charging.

3. Plug the jack of the external
adaptor into the charging port
at the end of the charging base.
4. Connect the external adaptor to the power source. Once the pool
vacuum begins charging, the indicator light on the external adaptor
will turn red. Normally, it takes about 4-6 hours to reach a full charge.
The indicator light will turn green when the pool vacuum is almost
fully charged.
NOTE: if the motor is generating noise, ensure “OFF” is selected on
the power switch.
5. When charging is complete, disconnect the external adaptor from
the power source and detach the charging base from the unit and
external adaptor.
Normally, the pool vacuum can operate up to 30 minutes on a full charge
(charged for 4-6 hours) .
Note: Clean the lter bag/lter cage regularly. Excessive debris inside
the lter bag/lter cage increases the burden to the motor operation
and shortens the operating duration as a result.
FACT: 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, running time of the pool vacuum will gradually
reduce through repeated charging and discharging in operation.
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.
· 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

• Do not use the pool vacuum if any damage is detected.
• Oil stain could occur due to possible leakage of lubricants applied
to the O-ring.
• Make sure the pool vacuum is fully immersed in the pool before
initiating operation. The minimum water level required to operate
the pool vacuum must reach above the power ON/OFF switch of
the pool vacuum when it is held in a vertical position. Operating
the pool vacuum when it is not immersed correctly could damage
the unit and void the warranty.
• DO NOT use the pool vacuum without an intact lter bag/lter
cage in place. Using your pool vacuum without an intact lter bag/
lter cage in place will VOID your warranty.

spa / hot tube. Otherwise it may bend the pole connector and damage it during the process.
2) To remove the pool vacuum from the pool / spa / hot tube, lift the pool vacuum while pointing it
downwards in order to allow water to escape from the outlet valve. Water is going to escape via the
handle / pole connector and draining holes inside the handle chamber on the rear body.
CAUTION! Make sure the pool vacuum is always facing downwards when it is removed from the
pool / spa / hot tube. Otherwise, the pole connector may be bent and damage the pool vacuum in
the process.
3) Rinse the pool vacuum with fresh water after every use. DO NOT use any detergent.
