About this deal
The Series 9 comes with a power2go charging case that allows the iO to be charged inside whereas the Series 8 comes with a standard travel case. Our in-house team has a couple that they feel are really beneficial: a pressure sensor, timer and pacer. The iO6 has them. A smarter pressure sensor than most I don’t believe it is a reason to ditch a perfectly functional brush in preference of the iO6, but it is a benefit should you make the switch. PROTECT YOUR GUMS WITH iO PRESSURE SENSOR, Oral-B's only one to signal if you brush TOO HARD, TOO SOFT or JUST RIGHT for an effective and safe clean. Each of the modes use different amounts of power from the motor. This impacts the angle of oscillation at the bristle tips to create brushing patterns and effects that are different from one another.
Plastic is the material of choice for good reason, but commonly used gloss finishes have been replaced with a matte finish that looks more refined. It has been awarded the American Dental Association’s Seal of Acceptance, confirming it meets the claims made by the manufacturer. iO specific heads are required for the iO6. The brush heads have gotten biggerTo my knowledge, all brushes have the same battery. All are claimed to last 2 weeks on a single charge.
The Series 8 has 6 cleaning modes (daily clean, sensitive, super sensitive, intense, whiten & gum care) compared to the 5 of the Series 7 (daily clean, sensitive, intense, whiten & gum care). The extra mode the iO8 has is super sensitive.If using the app, it will show on the screen if you are using the correct pressure or not. Aim to have a green light as you brush. Brush for longer with the help of the timer and pacer A second, lesser powered mode such as sensitive is a welcome addition for new electric toothbrush users, or those with gum disease or sensitivity.
