Oral-B iO vs Genius Pro 8000

Oral-B iO vs Genius Pro 8000

Editor’s Note

The Oral-B iO has been announced, but not yet released for general sale.

It is expected to go on sale to the public in late summer 2020, approximately August.

This comparison has been written to highlight the differences, based on what information we already know.

It will be updated once I have hands-on time with the final production unit.

Which one would we choose?

Our choice: Oral-B iO
2nd choice: Oral-B Genius Pro 8000

2 very capable brushes these are, but the iO is essentially 2 generations on from the Genius 8000.

The iO looks smarter, is quieter to use and perhaps most significantly, the real-time tracking of your brushing is much simpler to use on a daily basis.

The Genius Pro 8000 relies on a smartphone camera to track the brush handle, whereas the iO has sensors built-in.

Key Differences

  • The iO looks quite different to the Genius Pro 8000 with a premium design.
  • The 8000 is available in 4 color options (black, white, rose gold & orchid purple) compared to the 3 color options (white, black onyx & rose quartz) of the iO.
  • The iO has a new style of CrossAction brush head, that is similar, but different to that with the 8000.
  • The iO has a new frictionless motor which is quieter than the Genius 8000.
  • The iO offers an oscillating-rotating cleaning action with micro-vibrations as opposed to pulsations on the Genius Pro 8000.
  • An OLED display is built into the handle of the iO to display key data. The display enables easy navigation through the brush features and personalization: welcoming greetings, choice of brushing modes, language settings and reminders to change the brush head. This is not included on the Pro 8000.
  • 7 cleaning modes are available on the iO compared to the 6 on the Genius.
  • The visible pressure sensor on the iO lights up green when the correct amount of pressure is applied and red when too much force is used. The 8000 only lights up red when too much pressure is applied.
  • The iO has Artificial Intelligence (AI) and position detection sensors built into the brush handle, whereas the Pro 8000 relies on a smartphone camera to track the position of the brush in the mouth.
  • The 8000 comes with a suction cup smartphone holder.
  • The iO has a magnetic charging stand.
  • The iO can charge in just 3 hours compared to the 12 hours of the 8000.
  • The 8000 has a battery charging icon/LED on the front of the brush handle. This information is displayed on the OLED display of the iO.
  • The Genius 8000 has a travel case that allows the brush to be charged inside, the iO does not.

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.

Detailed comparison: what’s the difference between the Oral-B iO and Genius Pro 8000?

Given that at the time of writing the iO is not actually available for sale and I have not had any extensive hands-on time, I am not in a position to write a detailed comparison between these 2 models.

The bullet point list should give you a good overview of the differences.

I will update this section of the comparison once I have the additional information and hands-on use to be able to give you the feedback you require.

Does one clean better than the other?

The answer to this question will only be known when I get to go hands-on with the iO later in 2020.

It is my expectation that the brushing experience and results will likely be very similar, with no distinguishable difference.

This is typical of a lot of toothbrushes today. They all may perform slightly differently, and may under clinical conditions show better cleaning compared to another, however, clinical conditions and real-world use is very different.

For most users, the more positive effect can be seen and felt from perfecting their brushing technique and routine than picking 1 toothbrush over another.

That said, the iO is using a different type of motor to the Genius 8000, so there may well be some subtle differences.

The inclusion of OLED screen on the handle will provide information that has never before been so easily accessible.

What this means that there is a very strong argument that users like you and I will be able to achieve a better clean with the iO as we have more data and information at our fingertips.

I will of course report back, in detail when I have tested the iO and compared it to the Pro 8000.

Is one better priced than the other?

Yes, I expect the Genius Pro 8000 to be quite a bit cheaper than the iO.

The official price of the iO has not been confirmed, but based on historic price information, I can say with some certainty that the iO will command a premium over the Pro 8000.

The recommended retail price of the 8000 is $199-250.

However, as is common with electric toothbrushes, the actual selling price is considerably less, about 20% less.

When the 8000 first launched I paid $165.

It is now a few years since it launched and the average selling price is now somewhere around $140.

When the iO does go on sale, I suspect a retail price similar to the Genius X, that followed the 8000 at around $220-250.

However, I suspect from day 1 of it going on sale you will be able to buy it for around $175-200 .

As the iO goes on sale, the price of the 8000 will be reduced even more, and I would not be surprised if in time it was removed from the range entirely.

I suspect the price will drop to below $110 when the iO hits the shop shelves.

Only when the iO launches will we know for certain.

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.


The Oral-B iO is the brush to go for.

Whilst I have yet to go hands-on and test all of the features and functions, it has the technical specs and improvements over the Genius 8000, that make it the brush to buy.

The convenience of the way in which the position detection tracking is implemented is such that it makes complete sense. It is more user friendly.

That said, if you are in the market for a brush now, and you can’t afford to wait until late summer, then go for the Genius X, the upgrade over the Genius Pro 8000.

Your Opinions

Ultimately, whatever brush you decide upon, it is you who needs to make the decision; but do so based on which is best for your needs or that of the end user.

Only pay the price you are happy with and do not be led into buying something if it is not right.

Hopefully, I have presented the facts and made the whole decision process that little bit easier.
