The Oral-B iO 9 offers a few key advantages over the Oral-B iO 8. Here’s a breakdown of the differences:

  1. Additional Cleaning Mode: The iO 9 has an extra cleaning mode called “Tongue Clean,” which is specifically designed to clean your tongue and prevent bad breath. The iO 8 doesn’t have this mode.
  2. Enhanced 3D Tracking: The iO 9 uses 3D tracking to monitor 16 zones in your mouth, providing more detailed feedback on your brushing habits. The iO 8 only tracks 6 zones.
  3. Rechargeable Travel Case: The iO 9 comes with a rechargeable travel case that allows you to charge your toothbrush while on the go. The iO 8 comes with a standard travel case that doesn’t offer charging capabilities.
  4. Interactive Charging Dock (for iO 10): While the iO 9 doesn’t have an interactive charging dock, the iO 10 (the most advanced model in the iO series) does. This dock provides personalized feedback during your brushing sessions.
  5. Price: The iO 9 is generally more expensive than the iO 8 due to the additional features and enhancements it offers.

In summary, the Oral-B iO series 9 offers a more comprehensive cleaning experience with its extra cleaning mode, enhanced 3D tracking, and rechargeable travel case. However, if you don’t need these additional features, the Oral-B iO series 8 is still a great option with its powerful cleaning performance and smart features.
