Safety Precautions
• This product is a sensor designed specifically to detect the degree of pollutant residue in the
water while you are washing fruits and vegetables.
• This product uses UV light to detect residues. For safety reasons, this product does not
contain any anti-yellowing agents, therefore prolonged exposure to the UV lights it emits
may cause the certain parts of this device to turn yellow after time. This is completely natural
and does not affect the functions of the device, nor cause harm to humans.
• This product uses UV light detection, therefore before opening the bottom cover or cleaning
the device, ensure that the device is powered off or in Standby mode and make sure not
to look directly into the light source. Please seek medical help immediately if you feel
uncomfortable.

Getting Started
Charging your PureGo
Please follow the steps below to charge your PureGo
1. Place the PureGo onto the charging dock with the front side facing outwards.
(The side with the ASUS logo is the front side of the PureGo; the side with the
model name and certifications is the rear of the PureGo.)
2. Connect the cable from the charging dock to the USB power adapter.
3. Plug the USB power adapter into a power outlet.
NOTE:
• Ensure to wait until your PureGo is fully charged before using it for the first time. Your
PureGo is fully charged when the LED ring lights up green.
• This device uses a power adapter with a power input of 5V/2A. Ensure to use the
bundled power adapter when charging the PureGo.

10 PureGo User Manual
CAUTION!
• Ensure to follow the calibration tutorial and calibrate when using your PureGo for the
first time.
• You do not need to calibrate after every use, but we recommend calibrating your PureGo
periodically (once every 1 to 3 months, depending on usage frequency) to ensure
detection accuracy.
• We recommend recalibrating when changing usage locations to ensure detection
accuracy.
• There may be slight differences in the water quality of the same area during different
times. We recommend calibrating periodically, or calibrating when the PureGo APP
reminder appears.
CAUTION! To ensure the optical detection chamber is completely immersed in the water,
the belt should be below water level when your PureGo is placed into the water.
To Calibrate your PureGo:
1. Press and hold the Start/Standby button for approximately 1.5 seconds until
the LED ring lights up blue, then place your PureGo into clean water.
2. The LED ring will blink blue during
calibration. When the calibration process is
completed, the LED ring becomes a solid
blue light. The calibration process should
take about 25 seconds.

Belt
CAUTION! To ensure the optical detection chamber is completely immersed in the water,
the belt should be below water level when your PureGo is placed into the water.
Detecting with the PureGo when washing fruits or vegetables
PureGo's revolutionary smart water detection feature allows instant detection of
the amount of pollutants in the water once it is placed in the water.
When the LED ring begins blinking orange,
we recommend continuing with
washing the fruits and vegetables, or changing the water and soaking the
fruits and vegetables again. When the LED ring blinks green, the cleanliness of
the water is close to clean water.
NOTE: For more information on the LED descriptions, please refer to the table on page 7.
Recommended washing steps
1. Clean the surface of the leafy parts and dirt from the roots of the fruits and
vegetables using clean water or with a tool.
2. Soak the fruits and vegetables in clean water for approximately 1 minute to
allow agricultural pesticide or other residue such as dust to dissolve in the
water. PureGo's revolutionary smart water detection feature makes it so that
no buttons have to be pressed during the detection process; PureGo will
automatically begin detection once it is placed in the water.

12 PureGo User Manual
5. Remove the inedible parts of your fruits and vegetables.
NOTE: A short press on the Start/Standby button will start/end this session.
3. Continue washing the fruits and vegetables with a small trickle of water to
wash away agricultural pesticide or other residue on the surface of the fruits
and vegetables, while continuing the detection process with the PureGo.
4. The cleanliness is indicated by the LED ring on PureGo:
• Red (blinking): Lots of pollutants / impurities detected in the water, please
change the water or continue washing thoroughly.
• Orange (blinking): Medium amount of pollutants / impurities detected in the
water, we recommend continuing with washing the fruits and vegetables.
• Green (blinking): Low amount of pollutants / impurities detected in the
water; the cleanliness of the water is close to clean water. You can stop washing.

PureGo User Manual
Notes when washing fruits and vegetables:
• Please follow the recommended procedures and recommended water temperature (8°C
~ 35°C) when using PureGo to avoid detection abnormalities.
• This device is made to function in clear water. Do not use the device in other non clear
water aqueous solutions such as sodas, tea, or coffee.
• Clear water is the best solution when washing fruits and vegetables. We do not
recommend using commercial fruit and vegetable wash solutions, salt water, baking
soda, or vinegar as it may not be able to remove agricultural pesticide, and may even
prolong the degradation time of the agricultural pesticide, increase the chances of
chemical contamination of the fruits and vegetables, or result in detection abnormalities.
• Take care not to damage the surface of the fruits and vegetables when washing them, as
an excess of phytochemicals in the water may affect the detection accuracy. If you find
damages or bruises on the fruits and vegetables when washing them, we recommend
removing them from the water used for detection and rinsing them each individually.
• This device is used to assist with the washing of common fruits and vegetables. Do not
wash items that may contaminate the water such as tea leaves or herbal medicine.
• Cooked food cannot be used with the detection feature of this device.
• If your LED ring lights up red due to an error while washing the fruits and vegetables,
please refer to the following for help:
- Refer to the PureGo APP for troubleshooting steps
- FAQ on the ASUS website (https://www.asus.com/us/Networking-IoT-Servers/Smart-
Home/Smart-kitchen/PureGo-PD100/)
