The full Oral-B iO series breakdown from Series 5 through 10 are tiered by their handle display, charging speed, and A.I. tracking depth, while all maintain the same powerful iO Magnetic Drive System and core cleaning performance.
The entry-level smart options (iO 5 and 6) provide 5 cleaning modes, A.I. tracking via the app, and a visible pressure sensor; however, the iO 5uses simple backlit icons, while the iO 6steps up to an Interactive Black & White Display. Charging speed is slow for both, using a standard magnetic stand that can take up to 16 hours for a full charge, making them the most budget-friendly way to access the iO cleaning technology.
The premium and flagship models (iO 7 through 10) all feature the crucial upgrade of 3-Hour Fast Charging and progressively enhance the user experience. The iO 7retains the Black and white display and 5 modes, but adds fast charging. The iO 8introduces the highly desirable Full Colour Interactive Display and ups the mode count to 6.
The flagship iO 9 and iO 10 share the ultimate handle features: the colour display, the maximum 7 cleaning modes, and top-tier 3D Position Detection (16-zone tracking). The iO 10is set apart only by its iO Sense Smart Charger, which provides the real-time A.I. coaching directly on the charging base, eliminating the need to use the smartphone app during brushing.
