As a long-time tester and reviewer of high-end electric toothbrushes, I consistently see Oral-B dominating the premium market with their innovative designs. This often leaves consumers with one crucial question: Should you invest in the revolutionary, new-generation iO Series, or stick with the proven, reliable cleaning power of the Genius X?
To answer this, I’ve put their top models—the iO Series 9 and the Genius X—head-to-head. While both deliver an outstanding, deep clean powered by AI, they represent two fundamentally different technological platforms. The Genius Xoffers powerful, established cleaning and personalized coaching, while the iO Series 9is a complete redesign, focusing on a smoother, quieter magnetic motor, faster charging, and hyper-precise 3D tracking.
This comprehensive comparison explores those key differences to help you determine which sophisticated Oral-B device best suits your oral health goals and budget.
