    Always know when to replace your brush heads

    Always know when to replace your brush heads

    All brush heads wear out over time, so you'll want to keep an eye on yours to make sure you're still getting a great clean. Our BrushSync technology tracks how long you've been using your brush head for and how hard you've been brushing. The BrushSync replacement reminder on your handle and a short beep remind you when it's time to replace it.

    Switch between 2 modes: Clean and Sensitive
