4 modes, 3 intensities
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 mode pairing
Smart brush heads ensure you're using the
right mode and intensity for the best possible
clean. For an example, 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.
Built-in pressure sensor
You might not noti ce 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. 7 out of 10 people found this
feature helped them become a better brusher.
BrushSync replacement reminder
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.
Long-life battery
Your Di amondClean 9000 will last for up to
two weeks on a si ngle charge with regular use.
