    Pressure sensor lets you know if you're pressing too hard

    You might not notice if you're brushing too hard, but your DiamondClean 9000 will. If you need to ease up, the toothbrush will make a pulsing sound. It's a heads up to let your brush head do the work.

    BrushSync automatically selects the best mode for you

    Smart brush heads ensure that you're using the right mode and intensity for the best possible clean. When you are using the C3 Premium Plaque Control brush head, your DiamondClean 9000's BrushSync technology will automatically sync your brush head with the Clean mode to help whiten your teeth.
