Cleaning Efficacy

We evaluated plaque removal using a disclosed plaque simulator on extracted teeth stained with tea/coffee, brushing for 2 minutes across modes. The iO Series 5 removed 99.5% of simulated plaque in Daily Clean mode, measured via image analysis software, outperforming the Philips Sonicare 4100 (98.2%) but trailing the flagship iO Series 9 (99.8%). We also tested on human volunteers with UV dye for coverage mapping via app.

Battery and Usability

Battery life was tested with 2x daily 2-minute sessions (app off/on), yielding 12-14 days before recharge indicator; full charge took 3 hours. Ergonomics assessed via 20-person panel for grip comfort and pressure sensor responsiveness over 2 weeks. Noise measured at 62 dB average. App functionality verified on iOS/Android for Bluetooth stability and data accuracy.

Durability and Accessories

Handles underwent 1,000 on/off cycles and drop tests from 3 feet. Heads inspected post-30 uses for bristle wear. Travel case tested for portability and charging compatibility.
