The iO Series first launched in 2020, with the Series 7, 8 and 9. It has since evolved from 3 to 8 brushes.

The other big plus with the iO Series 9 is charging. You get not only two weeks’ worth of charge in just under three hours, but also a slimline travel case that allows you to charge the brush while in-situ. While it’s due to be superseded by the new iO Series 10, this is not just the best Oral-B toothbrush, but the best electric toothbrush you can buy.Yes, unfortunately, with the iO6, for example, when cleaning your upper front teeth if you spent all the time cleaning the outside surface (near your lips), and failed to clean the biting surface or inside surface (near your tongue), the iO6 would still think you had done a good job for that zone. Those models with a display will show a notification on the screen. If connected to the Oral-B app, a notification will be displayed here too for compatible models. All of the iO Series brushes have a 2 minute timer, pacer and pressure sensor. These are the key features that dentists recommend. If I were buying an electric toothbrush, the Pro 3 3500 from Oral-B would be my choice. It doesn’t have Bluetooth. To assess battery life, we leave the toothbrush running while standing up and time how long it takes for the battery to run down. We then divide this figure by the four minutes per day brushing recommended by dentists to get an accurate idea of how many days and weeks a single charge should last.
