Operating Instructions
Follow these steps for optimal use of your Bigsmile Water Flosser:
- Fill the Reservoir: Unscrew the bottom water reservoir and fill it with lukewarm water. The 200ml capacity is designed for a single use. Reattach the reservoir securely.
- Attach Nozzle: Insert a desired tip into the opening at the top of the flosser until it clicks into place.
- Select Mode: Press the power button to turn on the device. The flosser has three modes:
- Strong: For daily deep cleaning.
- Pulse: For gum massage and improved circulation.
- Gentle: Recommended for beginners or individuals with sensitive gums/teeth.
- Adjust Pressure: Use the touch & slide control strip on the device to adjust the water pressure between 5psi and 160psi. Slide your finger up for higher pressure, down for lower.
- Begin Flossing: Lean over a sink and place the nozzle tip into your mouth, aiming at the gumline at a 90-degree angle. Turn on the device by pressing the power button.
- Guide the Water Stream: Move the nozzle along your gumline, pausing briefly between teeth. Ensure the water stream reaches all areas, including between teeth and around braces if applicable.
- Finish: After approximately 1 minute of use, or when the reservoir is empty, turn off the device by pressing the power button. The irrigator will automatically stop after 2 minutes of continuous use to prevent idling.

Maintenance and Cleaning
Regular cleaning ensures the longevity and hygiene of your water flosser.
- Empty Reservoir: After each use, empty any remaining water from the reservoir.
- Clean Reservoir: The detachable 200ml reservoir can be easily unscrewed and cleaned with soap and water. Allow it to air dry completely to prevent mold or mildew.
- Clean Nozzle: Remove the nozzle and rinse it under running water. Store the tip in the reservoir tip storage or use the silicone dust cover when not in use, especially for travel.
- Wipe Down Unit: Wipe the main unit with a soft, damp cloth. Do not use abrasive cleaners.
- Drying: Leave the reservoir open to dry out completely when not in use for extended periods.
The device is IPX7 waterproof, meaning it can withstand water pressure at a depth of 1 meter. This allows for use in the shower, but proper drying after use is still recommended.

Troubleshooting
If you encounter issues with your Bigsmile Water Flosser, consider the following:
- No Power: Ensure the device is fully charged. Connect it to the charger and check the indicator light.
- Weak Water Stream: Check the water level in the reservoir. Ensure the nozzle is securely attached and not clogged. Adjust the pressure setting using the touch & slide control.
- Water Leakage: Ensure the water reservoir is securely screwed onto the main unit and that the nozzle is properly inserted.
- Accidental Setting Changes: The touch & slide control is sensitive. Be mindful of hand placement during use to avoid unintentional adjustments.
