The Oral B io series launched in August 2020 is the latest model in the Braun Oral B range. The new model Braun model comes in 3 versions the Oral B io 7 vs 8 vs 9. In May 2021 Oral B io6 was introduced to the io range. This means that it will take at least 12 hours to recharge, unlike io7,8,9 that will take only 3 hours to fully recharge, thanks to the magnetic charging technique. 

In general, the Oral B IO Series is markedly completely different from many other Oral B toothbrush versions that have primarily relied on the patented 3D technology of vibrations, pulsations, and oscillations.

Here are the general key advantages and disadvantages of the Oral-B iO toothbrushes (6,7,8 and 9)

Oral-B iO Series 6 vs. 7 vs. 8 vs. 9 Overview

User reviews:4.7/5.0

The new Series 6 offers an even more affordable model but retains some of the most desirable elements of the iO range.The key difference here is the charging stand.

The iO Series 6 does not come with a magnetic charging stand. Instead, it comes with a charging stand commonly offered with more affordable Oral-B brushes. Therefore you can expect a full charge of the iO6 to take around 12 hours, compared to the 3 hours of the iO7, iO8 and iO9.

A subtle difference with the charging of the iO6, compared to the other models is that the iO6 shows a precise battery percentage on the display. For example, 42%. It may well be that the firmware has been updated within the brush, but at the time of review, the iO 7, 8 and 9 only showed the battery charge in 10% increments. 

It comes with 5 cleaning modes and a black and white display, like the Series 7. And it has Bluetooth connectivity and various sensors for real-time tracking of your brushing.It retains the iO design language and only the iO specific brush heads work with the 6 Series.

Key Features

  • 5 Smart Modes for personalized brushing: Daily Clean, Whitening, Gum Care, Sensitive, and Intense.

  • Interactive display for real-time coaching.

  • AI recognizes your brushing style and guides you to better brushing every day.

  • Compatible with Oral-B iO Replacement Brush Heads.

  • Connects to the Oral-B app using Bluetooth to help you track your brushing habits.

  • Battery life of 14 days.

Price and Where to Buy:

Should You Buy the Oral-B iO Series 6?

Buy it if...

  • You want to improve your technique

Whether you use the smartphone app or not, the Oral-B iO Series 6 will give you valuable feedback that you can use to develop better cleaning habits that will serve you well in the long run.

  • The iO Series 9 is just too expensive

The Oral-B iO Series 9 is a superb brush, but its price might be off-putting. The iO Series 6 is a great alternative that doesn't compromise on the things that really matter.

Don't buy it if...

  • You're a frequent traveller

Oral-B has kept costs down by providing only a basic travel case for the iO Series 6. It's fine for occasional use, but if you're going to be off-grid and want to keep your brush charged for long periods, the iO Series 9 will suit you better.

  • Money is particularly tight

Although the Oral-B iO Series 6 is cheaper than the iO Series 9, it's still not exactly cheap. If you're looking for a good quality electric toothbrush on a budget, the Ordo Sonic+ is a solid choice that comes highly recommended.

  • The digital interface is a nice touch.

  •  Round brush heads offer a better cleaning experience. 

  • The vibrations aren't too strong nor as off-putting as other electric brushes.

  •  Long battery life. 

  • Helpful reminders on when to stop brushing and when to ease the pressure. 

  • Expensive. 

  • Brush heads are thick (and pricey to replace). 

  • The app doesn't always detect brushing spots accurately. 

  • Tongue-clean mode is available only on the most expensive model.

Should You Buy the Oral-B iO Series 8?

Yes, mainly for the fact that cleaning takes priority above anything else. All of its smart functions and tracking are extra. If it can’t succeed at cleaning, then it’s a failure.

      Which Oral-B iO Series Would We choose?

      1st choice: Oral-B iO Series 9
      2nd choice: Oral-B iO Series 7

      The iO Series 7 is the brush to go for based on features and price alone if I base this comparison on the recommended selling price of $199.99.

      The Series 9 is the top of the line model and will be more widely sold and promoted. However, it commands a $100 premium.

      For that extra $100 the benefits are a couple of extra brush heads in the box, a travel case that allows you to charge the toothbrush whilst inside and 2 extra cleaning modes.

      Conclusion

      The differences between each model in the iO Series are relatively subtle.

      As you will have seen it easily becomes confusing as to know which variant is best to buy.

      All of these brushes offer more than what you need.

      On paper alone, the iO Series 7 is the most sensible purchase based on what you get for the price. With a $100 premium price for the 9 Series, it is not the sensible choice for the limited differences.

      However, the reality is that the actual selling price, not the recommended, will be such that the Series 9 will be the logical buy because the price premium over the 7 Series will be justifiable.

      FAQ

      1.Is the Oral-B iO an oscillating brush?

      Yes, the circular brush head moves side to side and is supported by micro vibrations for extra deep cleaning. 

      2.What brush head does the iO come with and what alternative ones can be used?

      • 4 x iO ultimate clean brush heads are supplied with the Series 9 toothbrush.

      • You can purchase gentle care brush heads for the iO too.

      3.How do I turn on or off Bluetooth on the iO?

      Disable Bluetooth by entering the «Settings» menu on the interactive display-> Bluetooth -> disable. Follow the same procedure to enable Bluetooth again.

      4.Does Oral-B iO come with a travel case?

      Yes, a ‘power2go’ travel case is included in the box.

      5.Does  Oral-B iO come with a charger?

      Yes, a magnetic charging stand is included in the box, as is a power adapter for the travel case.

      6.How long does the battery last?

      • Claimed battery life of 2+ weeks.

      • Inconsistent battery performance but averaging around 14 days on Daily Clean mode.

      7.Does the Oral-B iO Series come with a warranty & how long is it?

      If purchased new from an approved retailer the brush will come with a 2 year.

      8.Are the iO Series toothbrushes waterproof?

      The iO’s handle is considered just water-resistant as opposed to waterproof. It’s OK to allow some moisture exposure and even to rinse it off under the tap. But don’t submerge it. It’s not built to withstand the pressure associated with that.

      9.Is there an Oral-B iO series 10?

      There is currently no Oral-B iO series 10, and a release date isn't set for a model with this name. At the moment, available series models are the iO series 6, 7, 8 and 9.
