Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison

Oral-B iO Series 6, 7, 8 & 9

Which one would we choose?

Our choice: Oral-B iO Series 9 (Amazon, Oral-B, Ebay)
2nd choice: Oral-B iO Series 6 (Amazon, Oral-B, Ebay)

All of the iO Series handles share many great features. They all have a 2 minute timer, pacer, smart pressure sensor, 2 week battery life and a stylish design to name just a few things.

Importantly, the cleaning action and results are the same irrespective of the model.

But, if you want the very best brush from Oral-B with all the newest features and you are prepared to pay for it, the iO9 is the brush to pick.

It has a travel case in which you can charge the brush. It can track 16 different zones in the mouth when you brush. It then gives personalized feedback, highlighting areas for improvement, so we achieve a better standard of brushing.

In reality, it is the iO6 that is the most sensible purchase for most people.

It offers a blend of premium features and performance at a more affordable price point. You get the in handle display and real-time tracking, but just 6 zones rather than 16.

iO Series 9 vs Series 10 (coming soon – some details TBC)

  • The iO10’s magnetic charging stand has iO Sense Technology to give visual feedback (via multiple LEDs) on the brushing routine. The iO9 does not have this.
  • The iO9 is available in 4 colors (black onyx, white alabaster, rose quartz & aqua marine) compared to the 2 colors of the iO10 (cosmic black & stardust white).
  • The Series 9 has a recommended retail price of $300, $TBC less than the $TBC of the Series 10.

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. Some very subtle configuration differences and app customizations are excluded. 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 Series 4, Series 5, Series 6, Series 7, Series 8, iO Series 9 and Series 10?

Since the iO Series launched in 2020, the range has increased from 3 different models to 7.

The range starts with the iO Series 4 and is topped off by the most feature rich and expensive model, the Series 10.

As the model numbers imply, the larger the number the more features and the higher the price tag.

The number of differences between each model in the range is fairly limited. Although if you compare iO4 to the iO10 then there are inevitably a few more.

Technically there are more similarities than there are differences.

Here is a list of ways in which all 7 models within the iO Series are the same. All of the models have:

  • Built-in timer (2 minutes)
  • Built-in pacer (30 seconds/quadrants)
  • Built-In smart pressure sensor – lit red when the pressure is too great, green when it is just right and white when there is insufficient pressure
  • Rechargeable lithium-ion battery offering 14+ days of use between charges
  • Bluetooth technology to connect to a smartphone
  • Frictionless magnetic drive system
  • Oscillating-rotating cleaning action with micro-vibrations
  • Use iO specific brush heads
Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison 63

So then, let me walk you through the main differences between these brushes.

One of the main differences is the number of brushing modes available on each handle.

You have the choice between 4, 5, 6, or 7.

7 is the maximum number of cleaning modes available on any Oral-B brush.

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

Cleaning ModesSeries 4Series 5Series 6Series 7Series 8Series 9Series 10
Number of Modes4555677
Daily CleanYesYesYesYesYesYesYes
SensitiveYesYesYesYesYesYesYes
Super SensitiveYesYesXXYesYesYes
IntenseXYesYesYesYesYesYes
WhiteningYesYesYesYesYesYesYes
Gum CareXXYesYesYesYesYes
Tongue CleanXXXXXYesYes

For most users, 1 mode, daily clean, is more than satisfactory. Although a second lower powered and more gentle mode such as sensitive can be appealing.

You don’t need lots of extra brushing modes. As I highlight later, the reality is the different modes don’t really affect the overall cleaning ability of the brush.

Each of the modes are designed to be run for 2 minutes. The only exception is tongue clean which is set for 20 seconds.

With each mode, differing amounts of power are used from the motor at different times. This impacts the angle of oscillation at the bristle tips to create brushing patterns and effects that are different from one another.

Just because the Series 7 does not have a tongue clean mode does not mean you can’t brush the tongue with the Series 7. You would just need to use a different mode.

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

Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison 64

All models bar the iO4 allow you to select the mode you want to use prior to turning the brush on.

The iO4 and 5 do not default to the last used mode either, whereas other models do.

5 of the 7 variants have a display built into the brush handle.

3 of them are color displays, whilst the other 2 are black and white.

Which models have what is shown in the following table.

iO4iO5iO6iO7iO8iO9iO10
Interactive DisplayXXBlack & WhiteBlack & WhiteColorColorColor

The black and white displays operate in the same way, but are just not quite as nice to look at. But in all honesty, it has minimal impact on your use of the brush each day.

They do too allow additional functionality not possible on those models without the screen.

For example, you can change the handle language, the color of the smart ring and even reset it right from the display.

With the iO4 and 5, you need to do these things from the smartphone app.

One of the biggest benefits of the display is that it makes it much easier to see which of the brushing modes you have selected.

There are no cleaning mode icons on the handle of the iO4.

The iO5 has 5 icons that get backlit but no actual mode name.

On the displays you get both an icon and the mode name, this makes it much easier to confirm which mode you are selecting and have set.

Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison 65

Another small but notable difference is the noise the motors/brushes make in operation. The iO4, 5 and 6 are quieter than the 7, 8 and 9.

Noise (dB)646464727272TBC

All models come supplied with at least 1 x Ultimate Clean brush head in the box, although some models come with more.

A brush head should be used only for 3 months, as after this time it tends to become less effective.

All iO models have a reminder system built into the app and into the brush handle. How this reminder is displayed differs.

The iO4 and iO5 have a yellow light that gets lit in the centre of the cleaning mode button. The handle will vibrate too.

Oral-B iO Ultimate Clean toothbrush head

Those models with a display will show a notification on the screen.

All of the iO models come with a travel case provided in the box.

The case will protect the brush handle from damage and accidental activation, whilst also protecting up to 2 brush heads.

There are some more differences between the cases to be aware of too.

iO4iO5iO6iO7iO8iO9iO10
Travel CaseYesYesYesYesYesYesYes
Brush Heads Held2222211
In Case ChargingXXXXXYes – uses separate power adapterYes – uses separate power adapter

As the table above shows, the most premium models, the iO9 and 10 have a travel case that only holds 1 brush head rather than the 2 of all the others.

This is in part due to the in case charging they offer.

What this means is that the rechargeable battery in either handle can be replenished, whilst inside the travel case, providing the proprietary power adapter is connected.

The power adapter is supplied in the box, but is specific to Oral-B.

The charging case doesn’t have a place to store the power adapter and the brushes can’t be charged via a USB cable.

100-240v is supported by the power plug.

Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison 66

It should be noted too that the quality of the case is better with the iO 7, 8, 9, and 10. They are a bit thicker and more durable.

The case color does also depend on the variant you select. Black handled brushes typically come with a black colored travel case and white cases with white handles.

Inside the handles of the iO Series is a rechargeable Lithium-Ion battery. All offer around 2 weeks of life on a full charge.

All the handles offer some feedback on the remaining charge, but how they do this is different.

Those with displays show on screen after each brushing session, a battery icon and a percentage reflective of the remaining charge.

The iO4 and 5 give feedback via the LED in the power button.

It will be lit with a white light most of the time. Only when the charge is around 10% or less will it pulse red.

Provided in the box with every brush is a charging stand. But these do differ depending on the model.

The 4, 5 and 6 all come with a standard Oral-B charger. This is the same as you would get with any rechargeable electric brush from Oral-B.

White in color, irrespective of your handle color, the brush fits only 1 way to it.

It takes 12-16 hours to recharge the brush using this stand which is compatible with 110-130v.

Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison 67

The magnetic charger provided with the iO 7, 8, 9 and 10 is certainly more premium.

The magnet holds the brush on the handle and it can be placed on in any orientation.

Whilst few of us ever need a toothbrush to recharge in just 3 hours, the stand will allow this. And comes in both black and white color options, subject to the handle color.

It also supports a wider voltage range. This means that if you were to travel to France from the USA for example, you need just a plug adapter and not a voltage adapter, like you would with the standard charging stand.

The iO10’s stand is a little more feature rich. It still charges the brush in the same way but it has extra notification LEDs as well as a clock on it as part of the iO Sense technology that is offered.

The final meaningful difference between these models is the color of the brush handles.

As a general rule, all models are available in black or white, but some are available in more options.

Black models tend to come with black colored heads and white, white heads. Other color handles may have either white or black heads, it varies per model and color.

Oral-B iO 9 Series Colored Handles

Does one clean better than the other?

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

All 7 models within the iO range use the same brush motor with the same configuration.

Yes, models like the 8 and 9 Series do have extra cleaning modes enabled compared to the 4 and 5. But, these modes don’t necessarily change the actual cleaning results.

Using the intense mode won’t necessarily remove more plaque from the teeth and gumline.

Instead, the modes alter the user’s experience and comfort with the toothbrush.

There are arguments to suggest a toothbrush that suits a user’s needs or wants better, can result in improved cleaning of the teeth. But, the evidence for this, particularly clinical data is basically non-existent.

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

If you want whiter teeth, it is fair to assume you need a whitening mode. But, you don’t need a whitening mode to make the teeth whiter. The standard daily clean can achieve this.

Factors like your brushing time, technique and toothpaste all have an impact on the results.

Oral-B iO Smart Pressure Sensor - Green

If your brushing technique is bad, there is an argument that the real-time tracking and Artificial Intelligence (AI) built into many of the iO models can help you achieve better results.

This is because it actually monitors how you are brushing and the areas you cover and for what time. Personalized feedback is then gained which you can use to take corrective action.

Real-time zone tracking varies from one brush to another

Not all the brushes have the same level of tracking.

The models and their abilities are shown in the following table.

At the bottom of this section I have also included a video to help explain the differences.

iO4iO5iO6iO7iO8iO9iO10
Real-Time Zone Tracking with AIXYes – 6 zonesYes – 6 zonesYes – 6 zonesYes – 6 zonesYes – 3D teeth tracking – 16 zonesYes – 3D teeth tracking – 16 zones

There is a strong argument to suggest that the iO9 and 10’s tracking of 16 zones can encourage you to brush all your teeth better than when you track just 6 zones.

The 16 tracked zones are as follows:

  • Upper rear right
    • Front surface
    • Biting surface
    • Inside surface
  • Upper font
    • Front surface
    • Inside surface
  • Upper rear left

Whereas the 6 zones tracked with the other models are:

  • Upper rear right
  • Upper front
  • Upper rear left
  • Lower rear right
  • Lower front
  • Lower rear right
Oral-B iO Series 4 vs 5 vs 6 vs 7 vs 8 vs 9 vs 10 Comparison 69

The Series 9 app screen is configured in such a way that you can clearly see which of the 16 zones you have and have not brushed.

16 dotted zones sit in the center of the on-screen display in a circular formation. As each zone is brushed correctly, that dotted zone disappears until no dotted zones remain and all the teeth on the large visualization turn white.

When only 6 zones are tracked, you can essentially spend all the time cleaning only 1 of the surfaces within that zone and the brush will still consider the zone brushed. That isn’t the case with the premium iO9.

The extra detail in the tracking can pick up on more specific, but important improvements needed in your brushing routine.

Of course, with any toothbrush, iO series or not, you want to be giving fair attention to all of the 16 zones so you have an even clean to the teeth and gums.

Thus, to master your technique the Series 9 does have that bit extra to push you to make sure you are making the correct contact with all surfaces.

But, how much difference this really makes in everyday use, is a bit subjective.

There is no long term data available that analyses if apps and real-time tracking do have a beneficial impact compared to someone learning the correct brushing techniques via other means and implementing them.

To better understand and see how the 6 and 16 zone3D teeth tracking works, watch the following video.

Oral-B 3D Teeth Tracking (6 vs 16 zones)

Is one better priced than the other?

Yes, inevitably, the ‘cheapest’ and most cost effective model in the range is the least feature rich model, the iO4.

It has the lowest retail price of $99.99.

However, it is quite often possible to purchase these brushes for a bit less than retail.

Whilst it is no guarantee, you can often achieve a discount of about 20%.

Thus the iO4 now drops from $80.

Compare this to the iO Series 9 which has a $299.99 retail price or a more realistic everyday ticket price of $240.

The following table shows the retail prices and average purchase price of each model.

It does also show the approximate ownership cost over 3 years for 1 person, when you factor in the purchase of replacement brush heads.

iO4iO5iO6iO7iO8iO9iO10
Recommended Retail Price (RRP)$99.99$119.99$149.99$199.99$249.99$299.99$TBC
Typical Purchase Price (approx 20% off RRP)$80$96$120$160$200$240$TBC
3 Year Ownership Cost (approx)$212$228$252$280$308$336$TBC

Of course, the table and quoted prices are just a guide. The actual selling prices vary from one retailer to another. Some models may work out even better value than those listed above.

As you might expect, models with extra features or increased box contents do command a premium.

Although the iO4 is the cheapest, it is the iO6 that is for most users the ‘best value’.

It has many of the most desirable features of the iO range, including the in handle display. But, it still remains relatively affordable.

You, therefore, get the best of both worlds as some would say.

The iO9, soon to be iO10 (when it begins shipping) will be the most technically advanced and serve those that want it all better.

Ultimately, pick the one you feel is best suited to you and pay a price you are happy to.

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

All things considered, the differences between each model in the iO Series range are relatively subtle.

No one toothbrush is going to result in drastically better cleaning results.

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

All of these brushes offer more than what you need.

You don’t need to spend as the iO Series commands to clean your teeth well.

The Oral-B Smart 1500 does a decent job for a fraction of the price! All things considered, we rate it as the best electric toothbrush.

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

Whilst the iO9 is the most capable, it is the iO6 that for most people is the most sensible purchase. It commands a premium, but it is a balance between feature sacrifice and price.

Of course, when it comes down to it, the choice is yours. All being well this comparison at least lets you make a more informed decision.

  1. There is one difference between the models that you have not mentioned, and may be important to some buyers. The series6 is single voltage (110-130v), whereas the Series 7,8,9, are dual voltage (110-220v).
    So, if you are travelling to Europe, Asia etc, the Series 6 cannot be recharged without a step down voltage converter.
    I found this out the hard way, as there is no mention of this in any literature or Specification information.
    I spoke to Braun Oral b, and they were extremely helpful in resolving my travel issue, but I think it is still worth bringing to buyers attention if they are going on any 2 week plus trip.

    • Hi Ian.
      Thanks for the comment and the information. You are indeed quite correct. This is a point that I have inadvertently overlooked.
      I will have the article updated very soon to reflect this.

      Reply
  2. Hi Jon, I am an avid reader not of just books…the good old ones that are hard cover or paperback, but also reviews, comparisons, things loved, problems, and blogs like yours, with all the things we buy.
    So, because I am on a limited budget I went with the IO8 series because I got it for $199 (same price as IO7) 20% off with Bed Bath Beyonds annual coupon program, any coupon will work…just not on the brush head replacements?? Not sure if it’s because they are $25 for
    2-Ultimate Cleaning….but 3 came with it so I have plenty of time and I may switch to the Sensitive Care due to receding gums from an Auto Immune Disorder since I was a child.
    I LOVE the interactive Oral B-App, I don’t mind that it shows only 6 quads vs 16 because I have always brushed well. I Love the smile/frown at the end…last night I only got half smile 😬 not sure what that was about. Also Love the Violet Ametrine color, hard black travel case-holds two brush heads, black magnetic charger, and black replacement heads that came with it. Only downsides: The Brush-heads are huge for a little mouth, I literally can’t get the brush between my cheek and teeth/gums without causing some serious pain to my gums & bleeding. I will be calling Oral-B, as I have only had it 5 days but the bleeding is better & my teeth are cleaner than they have ever felt. I have adjusted the way I clean my back teeth but it takes me much longer….like almost 4 minutes. The only other downfall is if the IO-9 has a better software program anyone who owns a IO7 or above or any IO Series should be allowed an upgrade to the 3D version, after all we are loyal customers, and spent a lot of our hard earned time and money on these brushes. The brand that failed me, hint…Diamond Clean, Rose/Pink I purchased 8/2016 was much more expensive, did less, and and the replacement heads were $10 more than Oral-B for 2-pk. Also, the whole arm moves not just the brush head/bristles like Oral-B, and the arm is so worn out that it won’t hold a charge because it’s overworking to compensate. Subsequently my gum recession has advanced and I pay to go to a speciality dentist, It also cost me A-LOT of money in dental bills for crowns, and an implant. I am excited to see how much my oral health improves, & can’t wait for my cleaning the end of April.
    Thank you for the in depth wonderful information/video and I hope all my blubbering helps some of y’all on the fence as I was, and/or on a limited budget that could use a coupon/discount…like me. Oral-B also has discounts currently on-going now as well, so do your homework and happy shopping and better dental health!

    • Hi Kim.

      I am not sure what books you are referring to as I haven’t written any?!

      Nonetheless thanks for the kind words and sharing your feedback with the iO8. It sounds like you are already seeing the improvements, even if it is resulting in a slightly longer brushing time.

      Reply
      • Sorry Jon, I meant I am just an avid reader of everything and I like the old fashioned way of reading…hard cover books.

        My only question is do you know of a smaller sized brush head for the IO Series? I see this complaint a lot on the reviews of all the IO Series.

        Reply
    • Kristi. I am afraid there is no place where these discounts are always applied, but they do drop from time to time. Over the last year the prices have remained higher than anticipated. Be sure to find the price you are happy to pay.

  3. I’m having Oral B Triumph professional care 5000 for the last 10 years, I guess. Has changed battery 4 times. In general it still provides good performance, but I don’t have other experience 🙂 Now I’m thinking switch it to iO 7. Will I notice any difference? What do you think Electric Teeth?

    Reply
    • I do think you will notice a bit of difference in the clean. It will likely feel a little more powerful. But fundamentally it isn’t going to clean the teeth any better.
      If the 5000 is still working, I would be inclined to stick with it. The brush heads are more cost effective for a start.

      Reply
  4. Can the carrying pouch that comes with the iO 7G accommodate both the brush handle and the small plastic case that holds the two brush heads? Is there room enough in it also for the charger? If space in a suitcase or backpack is a premium and the difference in cost between the 7 and the 9 is not a factor, would it make sense to choose the 7?

    Thanks,
    Peter

    Reply
    • If memory serves me correctly, the pouch case will hold the handle, heads (in their own case) and the charger.
      From an overall space point of view, I don’t believe there is really a great deal in it between the case for the Series 7 and 9. I haven’t done the maths.
      If space saving is the absolute priority here, it might be worth considering other products. But that comes with a whole host of other challenges. In short, the better toothbrushes still have bulkier cases.

      Reply
  5. Is it safe to say that the motor and battery are better on the series 9 over the 7?? If it’s the same then I agree with your assessment of the 7 being the better deal BUT if the motor and battery are better than I would def opt for the series 9.

      As far as I am aware, the handle and brush heads are made in Germany. The charger and travel case is made in China.

      This is subject to change, but it is the information taken from the box of the iO9 I purchased.

  7. Costco sells the 2 pack of the Oral-B iO series 7c for $199 when they put it on sale and the Oral-B Genius 2 pack (no model line specified but I think it’s the ​Genius 8000) for $99 when they put it on sale. Would you spend double the price for the Oral-B iO series 7c?

    Reply
    • Sam.

      No, as a general rule I would probably not spend twice the price.

      However, if it is the Genius 8000 that they offer the way it tracks your cleaning with the app is quite different. You have to use the camera on the front of your smartphone to track the position, rather than the sensors in the handle. This is quite frustrating for many, making the implementation on the iO much more appealing because it is so much more user friendly.

      If it is the Genius X that offer in that bundle, then I would go for that because the Genius X has the sensor built into the handle like the iO.

      Reply
      • Thanks. Even though I work in IT, I definitely don’t want to use my smartphone camera to track the position. I emailed Oral-B (Procter & Gamble) to ask them which Genius model is sold by Costco. On the Costco page it says “Bluetooth connectivity with real time feedback to improve cleaning habits” with a picture of a smartphone. Older reviews on the Costco page say it’s the Genius 6000 but it has 6 brushing modes not 5 like the Genius 6000 and one of the more recent reviews says this: As of 10/2020 the handle model is type 3765, which includes smartphone camera-based position detection and tongue cleaning mode. While the manual calls it the “Genius Pro 6000”, as far as I can tell it is the same handle as the Genius Pro 8000/9600 (USA).

        One more question. Which one has softer brush heads? Maybe it doesn’t matter because it has the pressure sensor.

        I’m not sure if I’m allowed to include links in my comment but here’s the link to it and maybe you can confirm which model it looks like to you.

        • Hi Sam.

          Well Costco/Oral-B are not making this easy to really understand.

          Sometimes Oral-B will do special packages and enable extra modes etc as a bit of an exclusive deal.

          I was inclined to think that it is the Genius 6000 with an extra mode.

          Yes, the 6000 connects to the phone and provides some feedback, but not real-time tracking to show which teeth have and have not been brushed.

          This technology has been reserved for the Genius 8000/9600/X and iO.

          Based on the number of reviews that mention the camera it would imply it is a version of the Genius Pro 8000/9600 which uses the front facing camera on your smartphone to track the position of the toothbrush.

          I am more inclined to trust the reviews than the Costco listing itself. Although it would be good to have clarification.

          If you don’t want to track your brushing, why not consider the Oral-B Smart Clean 360. Perhaps not technically quite as good value, but a solid brush. It is based on the Smart 1500 that we rate as our top pick for the USA.

          I hope that helps.

          Reply
          • Thanks again Jon. I’m also inclined to trust the reviews as well.

            I originally wanted the iO series 7 because Consumer Reports here in the US gave it a top rating but it is expensive for an electric toothbrush. But then I saw the Genius X also got an excellent review on CR and saw that the Costco version of the Genius was going on sale this month so I started to consider that one. I’ll take a look at the Smart Clean 360 as well. The features that are most important to me are the pressure sensor and timer. I also want to factor in the price of the replacement heads because that will add up over time.

            On a side note, many electronics manufacturers produce special models for warehouse clubs like Costco or simply change the model number slightly so that the major retailers don’t have price match to the warehouse club prices. For example Costco’s iO series 7 model is the 7c and was $199 for the 2 pack which is much cheaper than other retailers for a single pack.

            Reply
            • Thanks for sharing Sam.

              Yes indeed these manufacturers come up with lots of clever approaches don’t they!

              Oral-B have some of the more cost effective brush heads, compared to the likes of Sonicare for example.

              I think the Smart Clean 360 will be a great option. It has the timer, pacer & pressure sensor.

              Whatever you decide upon, please do let me know which you pick and what you think of it once you have used it.

              • Thanks again Jon. One last question. Do the Oral-B Smart, Smart Clean and Genius toothbrushes all use the same toothbrush heads? I know the iO series use a different head.

                  • Thanks Jon. Here’s what Oral-B (Procter & Gamble) told me in response to my question about the Costco Genius model.

                    This model is the same series as the Genius 6000 (3765). The only difference between these models (6000, 8000, & 9600) are the amount of speeds, accessories included, etc.

                    After looking at the Genius 6000 reviews on Amazon, I could see that some reviewers mentioned the camera functionality so it appears to have it. I was thinking the Costco Genius model was similar to the 8000 because of the 6 cleaning modes but maybe it’s just a version of the 6000 with 6 cleaning modes.

                    • Thanks Sam for sharing the reply from Oral-B. This is interesting.

                      I have clearly overlooked this part of the Genius 6000! It is very poorly communicated by Oral-B if it has this tech built in. Why not include some sort of phone holder? Without it you will have to hold the phone in front of your face really steady to track the position.

                      Not making it easy for customers are they!!

  8. I just bought the oi series 7 for my 15 and 17 year old boys which both have braces so I was looking to see if I could buy the different brush attachments such as the one for braces and if it’s interchangeable or do I have to but brushes that are specific to the oi 7…? Thank you

    • Hi Renee.

      Oral-B makes only 2 styles of brush head for the Oral-B iO. These are called the Ultimate Clean and Gentle Care heads. Both will work with braces.

      All other brush heads Oral-B offers are not compatible with the iO. They have a different fitting.

      Oral-B does make an ‘Ortho’ brush head for braces, but this is not compatible with the iO.

      The Ultimate Clean and Gentle Care heads should still provide a great clean to the teeth and braces of your sons. You don’t need a specific brush head.

  9. I saw a 2 pack series 7 at Sam’s club today for $146.00 so I bought it. Your review helps as I wasn’t sure about my purchase. Hopefully, I will like it.

  10. Thanks for the detailed review – it made the decision to buy the right brush for my husband easy – especially the various comparisons !! the travel charger feature in hte series 9 is great for my husband but with Covid he is not traveling….so perhaps the other option is not too bad and the extra $50or 100 is not justified

  11. Thanks Jon. Very informative.
    I like the fact you are highlighting the omission of simple USB charging. That alone would be £100 worth more to me as a frequent traveller.
    The different modes are somewhat a hoax. The reality is, you just use the standard mode all the time in the end.
    For me what makes this toothbrush interesting is the fact you can fast charge it, a more compact design and its quieter. Thanks again
