Operating Instructions

Once the unit is charged and the reservoir is filled, you can begin flossing:

1. Select Pressure Setting: For first-time users, set the pressure to LOW. You can increase to HI for a stronger clean as you become accustomed to the device.
2. Position the Tip: Lean over a sink. Place the flosser tip into your mouth, aiming it at the gumline at a 90-degree angle. Close your lips slightly to prevent splashing, but allow water to flow from your mouth into the sink.
3. Start Flossing: Turn on the Waterpik Ultra Cordless Water Flosser. Glide the tip along the gumline and between teeth, pausing briefly between each tooth. Ensure the water stream reaches all areas of your mouth, including the back teeth and inner surfaces.
4. Maintain Posture: Keep the unit upright during use to ensure continuous water flow.

• Drying: Allow the unit to air dry completely before storing or recharging.

Troubleshooting

If you encounter issues with your Waterpik Ultra Cordless Water Flosser, refer to the following common solutions:
