- Attach a Jet Tip: Select the desired jet tip and firmly insert it into the opening at the top of the flosser unit until it clicks into place.

Cleaning and Maintenance
Proper cleaning and maintenance will ensure the longevity and hygiene of your water flosser:
- Daily Cleaning: After each use, remove the jet tip and rinse it under clean water. Empty any remaining water from the reservoir and allow all parts to air dry.

- Waterproof Design: The device is IPX7 waterproof, allowing safe use in the bathroom or shower. Always ensure the waterproof cover on the USB-C charging port is securely closed during use to prevent water entry.

Troubleshooting
If you encounter any issues with your WELLLEO Water Flosser, please refer to the following common solutions:
