    The DiamondClean 9000 gives you the guidance you need to improve and maintain healthy brushing habits in between dentist check-ups.

    Personalised brushing experience

    Personalised brushing experience

    The DiamondClean 9000 comes with Clean, White+, Gum Health and Deep Clean+ to take care of your brushing needs. Clean mode is for exceptional everyday cleaning, White+ is for removing stains, Gum Health provides a gentle yet effective clean for gums and Deep Clean+ gives you an invigorating deep clean. Three intensities allow you to choose between a higher setting to boost your clean and a lower one for more sensitive mouths.

    BrushSync automatically selects the best mode for you

    BrushSync automatically selects the best mode for you

    Smart brush heads ensure you're using the right mode and intensity for the best possible clean. For example, let's say you're using the W3 Premium White brush head. Your DiamondClean 9000's BrushSync technology will automatically sync your brush head with the White+ mode to help whiten your teeth.

    Lets you know if you're pressing too hard

    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 reminder to let your brush head do the work. 7 out of 10 people found this feature helped them become a better brusher.

    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.

    Simple to charge and style to boot

    Your DiamondClean 9000 will last for up to two weeks on a single charge with regular use.
