The DiamondClean Smart 9700 is Philips Sonicare's top-tier rechargeable brush, with five modes, three intensity levels, a light-ring pressure sensor and Bluetooth coaching through the Sonicare app. It cleans at 62,000 bristle movements per minute and uses BrushSync to flag a worn head. It suits people who want app feedback and a premium finish, but it costs far more than mid-range Sonicare models that share the same core cleaning and pressure sensing. Owners rate it well overall, though some find the app and modes more than they use.

The Philips Sonicare DiamondClean Smart 9700 is a rechargeable sonic electric toothbrush in rose gold. It uses Advanced Sonic Technology to pulse fluid between teeth and along the gumline, with 62,000 bristle movements per minute. Compared with a manual toothbrush, it is stated to remove up to 20x more plaque, give up to 15x healthier gums and remove up to 100% more stains.
It has 5 brushing modes: Clean for daily cleaning, White+ for stain removal, Gum Health for gentle cleaning of the gums, Deep Clean+ for a thorough clean, and Tongue Care for fresh breath. There are 3 intensity levels. A light ring pressure sensor signals when you press too hard. QuadPacer and SmarTimer help you work toward the recommended 2 minutes of brushing.
Smart Sensor technology and the Philips Sonicare app over Bluetooth give personalized feedback and coaching on your brushing. BrushSync technology signals when it is time to replace the brush head. A USB charging travel case is included for trips, and the charging glass tops up the battery at home. The battery lasts up to two weeks on a single charge, based on two 2-minute brushings a day on standard mode.
