All iO models have a reminder system built into the app and the brush handle. How this reminder is displayed differs. Supplied in the box is a charging stand. White in color, it has a 1.2 meter (4 foot) cable hardwired into it. The plug on the end of the cable is a 2 pin power adapter. It supports 110-1300V. The great number of choices you have within the Oral-B range can make it really quite difficult to decide which toothbrush is right for you. There is potentially more e-waste generated as a result of the Bluetooth connectivity, but it’s not as bad as the handles in the range that have displays built in.

One of the biggest differences is that the Pro 2 2000, which is the more premium model offers an extra cleaning mode. This is a cycle that lasts for 20 seconds with 7300 oscillations and 30,000 pulsations and designed for as the name suggests, cleaning the tongue. This is because you have an onscreen timer to guide you. The idea is you spend 20 seconds per zone, to realize the even clean. You will see that the more feature-rich, and typically more expensive models are shown on the right, compared to the more cost effective models on the left.

A bigger difference and potentially useful feature for first time electric toothbrush users is the inclusion of a pressure sensor on the 2000. The Oral-B iO has been redesigned from the ground up. From the motor to the handle, to the brush head, it has all changed. 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.

Both do a job and give a home to brush heads, but the 9000 is a neater and more desirable solution. Decades of research, testing and manufacturing experience have gone into achieving the brushing results that the iO5 delivers. They are really good, I have no complaints. Nor does the American Dental Association. It’s been awarded their Seal of Acceptance. The iO5 has a brush head replacement reminder light in the cleaning mode button. The iO6 has this reminder on the display.The new magnetic driven motor is quieter and the way it works produces a cleaning sensation that is similar, but different.
