Maintenance
Proper maintenance ensures the longevity and hygiene of your water flosser.
1. Water Removal After Use
- Detach the water tank from the unit and empty any remaining water completely.

2. Cleaning and Care
- Wipe the exterior of the unit with a soft, damp cloth. Do not immerse the main unit in water.
- The water tank is removable for easy cleaning. Wash it with mild soap and water, then rinse thoroughly.
- Jet tips are consumables. Replacement is recommended every 6 months for optimal hygiene and performance.
- The handle is also a consumable part, and replacement is recommended every 12 months.
- When returning the handle to the unit, make sure the switch is facing the front. This ensures a correct fit and proper drainage.
