- After each use, rinse the brush head thoroughly under running water while the toothbrush is still on to remove any remaining toothpaste or debris.
- Turn off the toothbrush and remove the brush head.

- The toothbrush is IPX7 waterproof, allowing it to be safely rinsed under water.

2. Brush Head Replacement
