3. Flossing Procedure
After selecting the mode, press and hold the power button for 2 seconds to start the device. Place the nozzle tip into your mouth, directing the water jet at a 90-degree angle to your teeth. Keep your lips slightly closed to prevent splashing, but allow water to flow into the sink. Move the nozzle along your gumline and between teeth, pausing briefly between each tooth. Clean all areas of the mouth, including the back teeth and difficult-to-reach areas. The device has a 120-second auto-timer for optimal cleaning duration.
