The DiamondClean Prestige 9900 is Sonicare's top-tier rechargeable brush. SenseIQ tracks pressure, motion and coverage up to 100 times per second and adjusts intensity automatically, and the handle pairs with the Sonicare app over Bluetooth for guided coaching. It ships with a charging station and a travel case, and the pressure sensor warns you when you press too hard. It suits people who want the most automated clean Sonicare offers and will use the app; anyone who just wants a strong basic brush gets the same sonic cleaning from cheaper Sonicare models without the sensors.

Owners rate it highly for the clean and the pressure feedback, but many question whether the smart features justify the top-tier position. A recurring complaint is that the app and sensor alerts feel gimmicky after the novelty wears off.
