To turn the device on or off, press the 'ON/OFF' button located on the front of the unit.

5.2. Mode Selection

Press the 'Mode' button to cycle through the available cleaning modes. The device offers three distinct modes:

5.3. Usage Technique

For optimal results, lean over a sink. Place the nozzle tip into your mouth, aiming the water jet at a 90-degree angle to your teeth and gumline. Close your lips slightly to prevent splashing but allow water to flow out into the sink. Guide the water jet along your gumline and between each tooth. Ensure you clean both the outer and inner surfaces of your teeth. For best oral hygiene, use after brushing your teeth.
