Oral-B iO Series 7 vs Series 8 vs Series 9

Oral-B iO Series Comparison - Header Image

Which one would we choose?

Our choice: Oral-B iO Series 9 (view on Amazon)
2nd choice: Oral-B iO Series 7 (view on Amazon)

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 £400.

The Series 9 is the top of the line model and will be more widely sold and promoted. However, it has a £500 price tag.

For that extra £100 the benefits are notably the 3D tracking and a travel case that allows you to charge the toothbrush whilst inside.

This therefore is not a justifiable premium in my mind over the Series 7.

But, the reality is that it is very likely that the iO Series 9 will actually sell for much less than its retail price and I suspect will actually sell on average around £250, thus making it a potentially justifiable premium for the extras it offers.

These differences are explained at length later in this article. However, you might wish to learn more about each brush being compared. To do so, check out our hands-on reviews:

Please note. Every effort is made to ensure the key differences listed are correct, but these differences are subject to change without notice. Products and the box contents can be changed without notice and different variants can exist.

iO Series 9 White Alabaster

Detailed comparison: what’s the difference between the Oral-B iO Series 7, Series 8 and iO Series 9?

The number of differences between the Oral-B iO 7, 8 and 9 Series is not as significant as you might expect.

Technically there are more similarities than there are differences. Here is a list of ways in which all 3 series of the iO are the same. All of the models have:

  • Built-in timer (2 minutes)
  • Built-in pacer (30 seconds/quadrants)
  • Built-In pressure sensor – lit red when pressure is too great, green when it is just right
  • Rechargeable lithium-ion battery offering 14+ days of use between charges
  • Bluetooth technology to connect to a smartphone
  • AI technology to track the location of the toothbrush in the mouth
  • Frictionless magnetic drive system
  • Oscillating-rotating cleaning action with micro-vibrations
  • Magnetic charging stand
  • Quick charging – in around 3 hours
  • Interactive OLED display to provide real-time feedback and encouragement
  • Travel case to at least store and protect the handle and 1 brush head

It is primarily the box contents, number of cleaning modes and price that differs.

The top of the line Series 9 comes with 7 cleaning modes, whilst the 8 comes with 6 and the 7 comes with 5.

The modes and which model has what are listed in the following table.

ModesSeries 7Series 8Series 9
Number567
Daily CleanYesYesYes
SensitiveYesYesYes
Super SensitiveXYesYes
IntenseYesYesYes
WhitenYesYesYes
Gum CareYesYesYes
Tongue CleanXXYes

The different cleaning modes are far from essential and not needed. The extra modes have slightly different cleaning times and settings which may make them more suitable or practical for some.

Just because the Series 7 does not have a tongue clean mode that would last for 20 seconds on the Series 9, does not mean you can’t brush the tongue with the Series 7. You would just need to use a different mode.

The lack of additional modes does not ultimately have any bearing on the cleaning results.

To learn more about the differences, do read our Oral-B cleaning modes explained article.

Oral-B iO Brushing Modes

All 3 of the variants have an interactive OLED display, however where the 8 and 9 series have a colour display, with the series 7 it is black and white.

Where the iO Series 9 stands out over the other models is the inclusion of the 3D tracking. All have the AI to work out the position of the toothbrush in the mouth, but only the Series 9 offers a 3D representation of this within the feedback that the brush and app offers. Essentially, the top of the line model makes it easier to visualize where you are doing things right and wrong.

All models, bar the Series 7 come in both a black onyx and white alabaster colour option.

With the Series 8 and 9, there is the choice of a third colour.

That choice is violet ametrine in the Series 8 and rose quartz with the Series 9.

The difference here is the colour of the toothbrush handle only.

With the black onyx models, the handle, heads, charging stand, travel case and power adapter are all black in colour.

With the white alabaster the handle, heads, charging stand, travel case and power adapter are all white in colour.

When it comes to the rose quartz and violet ametrine variants, the handles are either colour, but all the accessories are white.

Oral-B iO Series 9 Handle Colours

With the Series 7 and 8 the travel case holds the brush handle and up to 2 brush heads. However, the travel case with the 9 Series holds the brush handle and just 1 brush head.

However, the 9 Series has an extra feature not available on the 7 and 8.

Called ‘power2go’ the travel case with the 9 Series allows the iO to be recharged whilst sat inside.

The toothbrush is charged via a detachable power adapter.

The brush cannot recharge without the power adapter being connected.

The power adapter is proprietary to Oral-B products. It does not use the more desirable USB Type-C charging.

Oral-B iO Series 9 Box

These differences have a knock-on impact on the price. There is a £100 difference in the recommended price of the 7 Series compared to the 9 Series. £400 compared to £500.

The Series 8 is in the middle at £450.

These differences are because of the perceived value Oral-B places on the additional box contents and features each model offers.

Does one clean better than the other?

No, simply put they all clean as well as each other.

Yes, the 8 and 9 Series does have extra modes compared to the 7, but these modes don’t necessarily alter the actual cleaning results.

Instead the modes alter a users experience and comfort with the toothbrush.

There argument to suggest a toothbrush that suits a users needs or wants better can result in a better clean of the teeth. But, the evidence for this, particularly clinical data is basically non existant.

For many years Oral-B and other brands have offered multiple cleaning modes on electric toothbrushes and I have yet to say any meaningful data to suggest these extra modes pay dividends for the majority of users.

Is one better priced than the other?

Yes, the Oral-B iO Series 7 is the best value at £400.

The 8 Series commands a £50 premium, making it £450 and the 9 Series comes in at £500.

Yes, the 8 and 9 do offer a fraction more as part of their packages, but the ‘extras’ don’t really add up to the real world price difference.

The logical and most sensible purchase of these therefore is the Series 7.

But, lets take a reality check.

These are ridiculous prices and the reality is that the typical selling prices will be at least 50% less.

This therefore makes them £200, £225 and £250 respectively.

Do bear in mind that it is highly likely that extra resource and availability will be placed on the range topping Series 9.

I wouldn’t be at all surprised if the selling price at times is basically the same if not cheaper than the 7 series. Therefore making it almost silly not to go for the most premium option.

For around a £30 premium the 9 Series is worth it over the 7.

But ultimately, pick the one you feel is best suited to you.

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Conclusion

The differences between each model in the iO Series is 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.

You do not need to spend as much as this or find a toothbrush with as many features as the iO Series to clean your teeth well.

The Oral-B Pro 2 2500 does a decent job for a fraction of the price!

That said, the iO marks a major design change in the Oral-B line up of products and is considerably quieter.

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.

  1. Dear Jon,

    Thanks for your work. I am in the market for an Oral-B iO 9 and I see that sometimes the package mentions “Series 9” while some other times “Series 9N”.

    I haven’t been able to understand the difference between the two, can you please help here?

    Kind regards.

    • Hi Ed.

      Yes, it is confusing and I am not 100% I can tell you precisely why they have different names, but what I have gleaned so far is.

      For other brushes in the past ‘N’ has usually referred to the standard brush head, ‘CrossAction’ or in the case of the iO Series ‘Ultimate Clean’.

      N seems to be the badge placed on models sold in central Europe. I note you might be in Italy, so this would apply here. Whereas in the UK it is just referred to as Series 9.

      The other difference, from what I can tell is the 9N comes with 2 pin European power adapter, which would apply for Europeans in the likes of Italy, Germany, France etc.

      In the UK we have 2 pin power in our bathrooms, but the pin size is different!

      As far as I am aware there are no technical/performance differences between these models.

      I know this is not a definitive answer, but I hope it helps.
