Philips' inductive charging glass returns on the DiamondClean Smart 9300, along with real-time app coaching on pressure, motion and coverage. It keeps the 9000's four modes but adds a pressure light to the vibration, and ships an A3 All-in-One head with the C3.

Pressure sensor and ADA Seal

Multi-signal pressure sensor. Philips Sonicare's description: Ring lights up purple, with vibration and a pulsing sound.

No ADA Seal listing found for this model on the ADA’s own product search. That is not a failed test: the Seal is voluntary and makers apply for it product by product.

These are facts about features and listings, not a statement that the brush prevents or treats anything. What a pressure sensor does · What the ADA Seal means

Three years of ownership

Handle: $230
Heads (10 × $6.66): $66.60

12 heads over 36 months at Philips Sonicare's stated 3-month interval, less 2 heads in the box. Head price: Sonicare SimplyClean 6-pack (HX6016/77), $39.96 on usa.philips.com. How this is worked out

What the extra money buys: Same 62,000 brush movements / min and a pressure sensor as the Philips Sonicare Series 5700; the extra $150 buys 2 more modes, app tracking, a multi-signal pressure sensor, a travel case, a charging glass and 1 more head in the box. See the Philips Sonicare Series 5700.
