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 gives you a heads up when it's time to replace it.
