5. Operating Instructions
- Power On/Off: Press the 'POWER' button to turn the device on. Press it again to turn off.
- Select Mode: After powering on, press the 'MODE' button (or the same power button if it cycles modes) to cycle through the available modes: Strong, Standard, and Soft. Select the mode that suits your comfort and cleaning needs.
- Flossing Technique: Lean over a sink. Place the nozzle tip into your mouth, aiming it at the gumline at a 90-degree angle. Close your lips slightly to prevent splashing while allowing water to flow into the sink.
- Clean All Areas: Guide the water jet along the gumline and between teeth. Pause briefly between teeth to allow water to clean the interdental spaces. Use the 360° rotating nozzle feature to reach all areas of your mouth, including the back teeth.
- Tongue Cleaning (with Tongue Scraper Nozzle): For fresh breath, use the tongue scraper nozzle. Place it on your tongue and gently pull forward, rinsing the nozzle after each pass.
- Completion: When finished, turn off the device. Empty any remaining water from the tank.
6. Maintenance
Regular cleaning and maintenance will prolong the life of your oral irrigator:
- Daily Cleaning: After each use, empty any remaining water from the tank. Rinse the tank and the nozzle under running water.
- Deep Cleaning (Tank): Periodically, fill the tank with warm water and a small amount of white vinegar (1:1 ratio) to prevent mineral buildup. Run the solution through the unit until the tank is empty. Rinse thoroughly with clean water.
- Nozzle Cleaning: Nozzles can be cleaned with warm soapy water. Replace nozzles every 3-6 months or sooner if they become worn.
- Unit Exterior: Wipe the exterior of the unit with a soft, damp cloth. Do not immerse the main unit in water beyond its IPX7 rating.
