      The DiamondClean Smart has some handy sidekicks—its connected app and smart sensor suite. They work together to give you confidence in your oral care.

      DiamonClean Smart sensor suite
      Feature 1 - Real time feedback
      Our smart sensors take the guesswork out of brushing. Real-time feedback helps get your brushing technique to 100%.
      Feature 2 - Missed spots
      The location sensor tracks your coverage, so you can see exactly where you've brushed, and where you've missed. That way you can get 100% coverage, 100% of the time.
      Feature 3 - Brush head delivery automatically
      Brush head reordering service automatically orders new brush heads for you - powered by Sonicare's BrushSync technology, tracking your brush head's actual usage. 

      Smart Brush Head Recognition

       

      This toothbrush knows the optimal mode and intensity setting for each brush head.

       

      So if you click on Premium Gum Care, for example, it automatically selects the best settings to gently yet effectivly clean your gums.
