The Oral-B iO Series 5 and Series 6 mark the jump into the brand’s smart, mid-range cleaning tier, offering app connectivity and a greater selection of cleaning modes. Both models feature the core iO magnetic technology, full-range iO Pressure Sensors, 5 cleaning settings, and real-time AI coaching via the Oral-B App.
The iO Series 5 is the introductory smart model. It provides excellent cleaning and a simple Smart Display for real-time coaching via the app. It’s the ideal choice for those who want app-tracking and the full 5 modes at the best price point.
The iO Series 6 is the step-up model, justifying its higher price with a slightly more robust on-handle display. This makes the Series 6 the premium option for users seeking the most aggressive deep clean and a more comprehensive on-handle user experience.
If app connectivity and full gum protection are your only goals, the Series 5 is a strong contender. However, if you require a clearer, more interactive Smart Display right on the handle, the Series 6 is the superior choice.
