Thank You For Purchasing a Oral Irrigator
Model: FC5090
User Manual
Portable Oral Irrigator
Thank you for choosing a oral irrigator!
You’re on your way to a more hygienic life!
Thank you for purchasing a portable oral irrigator from, a pioneering and
innovative brand with the world's most advanced high-pressure water
pulse technology.
Conventional toothbrushes cannot easily remove food debris hidden in
the oral cavity, while most dental floss can only reach a limited area
under the gums. In contrast, oral irrigators can quickly and efficiently
remove food debris from deep in the gums and between the teeth to
ensure perfect hygiene.

full, and all the charging indicators are on. You can
press and hold the mode button to check the current
battery power, which is indicated by the number of
indicators that are on. If the charging indicator flashes
during use, you need to charge the device. When the

After use, open the water tank and pour out any remaining liquid. Turn
on the device and drain any liquid left until the irrigator no longer sprays
out any liquid, then turn off the device.
Step 6: After Use
Step 7: Charging
Step 4: Before Use
Press and hold the switch button for 0.6 second to start the device. To
pause the device during use, tap the switch button. Press and hold the
button again to resume operation. This device is equipped with a
120-second shutdown timer. Automatic shutdown will only trigger if the
water tank is empty. If you wish to keep using the device, tap the switch
button to turn it off, then restart the device after refilling the water tank.
Turn off the device after you are finished using it.
Step 5: Use
For best results, start with the molars (posterior teeth) and start cleaning
towards the front teeth. While cleaning, move the nozzle 90° along the
gum line. Stay between each tooth for a short period. Close your lips
slightly to avoid the water from spraying out, but leave enough space so
that water can flow freely from your mouth to the sink.
Techniques
Before using the device, lean slightly over the sink, extend the nozzle
into your mouth and aim it at the teeth, gums, or between the teeth.
Rotate the nozzle to adjust the direction of the water outflow so that it
is perpendicular to the part of your mouth you wish to clean. Ensure that
your mouth is open enough so that any water flows right out.
IV. Cleaning and Maintenance
1. Clean this device only with clean water or a neutral detergent. Do not
use corrosive or abrasive detergents. Do not use water above 50℃ to
clean any part of this device, as this may lead to damage or reduced
performance.
2. Do not soak the oral irrigator in water. If necessary, clean the surface
of the device by wiping with a soft cloth dipped in mild, non-corrosive
detergent.
Cleaning the Body:
1. You can hold the device with your left hand, seize
the buckle of the cover with your right hand, rotate
the buckle left and right, then gently pull it down.
2. Rinse the inside of the tank with clean room
temperature water. Do not clean the tank with any
type of detergent.
3. After cleaning, locate the bottom cover to the
buckle, then gently insert it to the device.
Cleaning the Tank:
Removing Hard Water:
Note:
When using the oral irrigator for the first time, start from the lowest
gear. Water pressure can be gradually increased as the oral cavity
adapts. You may experience itching or minor gum bleeding during use.
This is normal and should typically stop after 1-2 weeks.
The indicator light is white, and will remain on while the device is in use.
If the device shuts down after the indicator flashes for five times, the
device is in low-voltage state. In the low-voltage state, after you press
the on/off button again, the device will not power on. The indicator
flashes for four times, indicating that you need to charge the device in
time. When the device is charging, the indicator flashes. While the
device is fully charged, the indicator light will remain on.

After use, open the water tank and pour out any remaining liquid. Turn
on the device and drain any liquid left until the irrigator no longer sprays
out any liquid, then turn off the device.

2. Battery Recycling
1. Battery Maintenance
Ensure that the battery is fully charged before initial use.
Ensure that the battery is fulled charged before storing the device for
an extended period.
In order to prolong battery life, charge the device immediately when the
battery is low.
This device uses recyclable rechargeable batteries. At the end of the
device's lifecycle, recycle or dispose of the batteries separately in
accordance with your local waste management regulations before
disposing of the device.
Recycling Procedure: While the device is turned off, remove the nozzle
and water tank, then use a screwdriver or a similar tool to pry open the
base to remove the recyclable batteries.
(Note: Do not short circuit the positive and negative terminals of the
removed battery. The terminals can be insulated with tape.)
1. Depending on the mineral content of the water used, hard water
deposits may build up on the device. Failure to remove hard water
buildups will reduce product performance.
2. Point the nozzle at the sink, turn on the device, then let it run until all
water has been used. Fill the water tank with clean warm water, then
repeat the above steps to clean the tank. This cleaning process should
be repeated every 1-3 months to maintain product performance.

battery is low.
This device uses recyclable rechargeable batteries. At the end of the
device's lifecycle, recycle or dispose of the batteries separately in
accordance with your local waste management regulations before
disposing of the device.
Recycling Procedure: While the device is turned off, remove the nozzle

removed battery. The terminals can be insulated with tape.)
1. Depending on the mineral content of the water used, hard water
deposits may build up on the device. Failure to remove hard water
buildups will reduce product performance.
2. Point the nozzle at the sink, turn on the device, then let it run until all
water has been used. Fill the water tank with clean warm water, then
repeat the above steps to clean the tank. This cleaning process should
be repeated every 1-3 months to maintain product performance.

User Manual
Portable Oral Irrigator
Thank you for choosing a oral irrigator!
You’re on your way to a more hygienic life!
Thank you for purchasing a portable oral irrigator from, a pioneering and
innovative brand with the world's most advanced high-pressure water
pulse technology.
Conventional toothbrushes cannot easily remove food debris hidden in
the oral cavity, while most dental floss can only reach a limited area
under the gums. In contrast, oral irrigators can quickly and efficiently
remove food debris from deep in the gums and between the teeth to
ensure perfect hygiene.
