As has become quite standard on electric toothbrushes now, a built-in timer signals when your brushing time is up and a quad-pacer tells you when it's time to move to a new section of your mouth. For the standard Daily Clean mode, this is set to two minutes broken into four 30-second intervals. You can adjust these settings via the app if you wish. The red light is accompanied by a slight reduction in the motor speed. You can customize the color displayed on the LED ring when the brush is on but not in use; a fun but completely unnecessary feature. If you don't have the app open as you brush, some information will still be stored in the brush and transmitted to the app next time you open it. Charging and battery life This is not a completely novel idea; the Oral-B Genius X and Sonicare DiamondClean Smart both offer similar technology.
The pressure sensor is also not a particularly novel feature, although the iO brings a new twist to it. Using the light ring around the handle, it not only tells you if you're applying too much pressure (red) but also if you're not applying enough (white). You're aiming for green, which shows you're doing it just right. The good battery life means you might not need to charge it while you're away. But considering that the charging travel case is one of the premium features of the iO9, it doesn't really add much to the product.

A timer shows how long you've been brushing for, although it's hard to view this without stopping and taking the brush out of your mouth. It should go without saying really, the iO toothbrush leaves your teeth feeling super clean. You'd expect that from a toothbrush that has six years of research and over 250 patents behind it.
The iO travel case could be executed better. It's certainly handy to have a protective case when you go away, but this one only has space for one brush head. If you need to take another, you'll have to bring the refill holder along as well.To fix this, try running the toothbrush’s top section (around the plastic connector and metal shaft) under warm water for at least ten seconds. Then, see if you can pull the extra bit off. You might have to give it quite a forceful tug, but it should come right off. If it does, your new brush head should fit. The way the motor delivers power makes it feel gentler than previous models, too. Not in a less effective way, but certainly less aggressive. Timer and pressure sensor If you use the more intense brushing modes, brush for longer, or share it with other members of your household, then of course this will reduce. In any case, it's bound to be an improvement on any other Oral-B toothbrush you own. It has also outperformed its main competitor, the Sonicare DiamondClean. In a similar study comparing the two brushes, 84% of people using the iO had healthy gums after eight weeks versus 53% who used the Sonicare. The new brush heads are presumably necessary for the new style of motor, but unfortunately they are not compatible with Oral-B's older toothbrushes. Nor are the older style heads compatible with the iO.
A charging travel case is a great idea, but unlike many other brands which supply a USB cord, the Oral-B case has a special main charger. This makes it much less compact, taking up almost as much space as the regular charging base. The idea is that all of this technology in the iO trains you to brush your teeth more effectively. Over time, you should see your score improve. Interspace: to be used on top of your daily brush head, for deep clean in hard-to-reach areas and healthier* gums
Sensitive Clean: for a gentle clean, comes with ultra-thin bristles that are tough on plaque but gentle on gums
