Oral-B iO Series comparison

Author: Jon Love (46 Comments)
All iOral-B O Series toothbrushes side by side

The iO6 is the best value, the iO9 is the best if you want the tech

Best value: Oral-B iO Series 6 (iO6) / Amazon, Oral B / ~$140.9

Best budget: Oral-B iO Series 3 (iO3) / Amazon, Oral B / ~$79.97

Best tech: Oral-B iO Series 9 (iO9) / Amazon, Oral-B / ~$249.94

Our verdict

All of the iO Series brushes have a 2 minute timer, pacer and pressure sensor. These are the key features that dentists recommend.

All models clean your teeth as well as each other.

What sets them apart are additional features. Examples include more brushing modes, in-handle display and ‘smart’ (Bluetooth) technology. These are nice-to-have, but not critical.

The iO6 is the best value option. It strikes the balance between additional features and price. It has some smart features, but not the full suite. 

Technically, the iO2 is the most affordable, but we recommend the iO3 as we think it is a better buy because of the pressure sensor setup compared to the iO2. The iO3 does not have smart features.

The iO9 is for those who want all the tech and are prepared to pay for it. It offers far more than you need.

Which cleans the best?

A reasonable question, given the range in price.

But, simply put, they all clean as well as each other.

All models within the iO range (except the iO2) use the same brush motor with the same configuration.

Models like the 8 and 9 Series do have extra cleaning modes compared to the 3, 4 and 5. But, these modes don’t change the actual cleaning results.

Using the intense mode won’t necessarily remove more plaque from the teeth and gumline. You don’t need a whitening mode to make your teeth whiter — the daily clean mode can achieve this.

Your brushing time and technique have a far bigger impact on the cleaning results than the mode you use.

What sets the brushes apart is the other features they come with. We compare these throughout the article.

Detailed comparison: the main things to know about the iO range

The iO Series first launched in 2020, with the Series 7, 8 and 9. It has since evolved from 3 to 9 brushes.

The Series 2 is the entry-level model. This is the least feature rich and most affordable.

The higher the model number the more features and the more expensive it is. The range topping model is the iO Series 10.

The complete iO Series (excluding iO2)- iO3 through to iO10 from left to right

They are similar in more ways than they are different

All of the models have the following features:

  • 2 minute timer
  • 30 second quadpacer (20 second sextant pacer on iO10)
  • Smart visible pressure sensor (not available on the iO2)
    • Lights up red when too much pressure is applied
    • Lights up green when the correct pressure is applied
    • Lights up white when there is insufficient pressure
  • Rechargeable lithium-ion battery offering 14+ days of use between charges
  • Bluetooth technology to connect to a smartphone (the iO2 & iO3 are the only exceptions)
  • Quieter, frictionless magnetic drive system (the iO2 has a linear pulse drive mechanism)
  • Oscillating-rotating cleaning action with micro-vibrations
  • iO-specific brush heads
  • Cleaner, more minimal design compared to other Oral-B models

Various price points to suit different budgets

$65 is the price for the most affordable model, the iO2.

The most feature-rich brush is the iO10. It costs $320. That's a difference of $256 for some extra cleaning modes and smart technology tracking features. Justifying this premium is very difficult.

But these prices account for the typical 20% discount on retail prices. $320 is the difference if we compare the ‘recommended retail prices’.

All brushes in the range use the same iO specific brush heads. Whether you opt for the iO3 or iO10, the long term ownership cost will be impacted most by the initial purchase price of the brush handle, not the heads.

$300 $240 $335
$400 $320 $416

Of course, the table and quoted prices are just a guide. The actual selling prices vary from one retailer to another. 

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

The iO2 is the cheapest and has the essentials anyone needs, albeit we prefer the pressure sensor implementation on the iO3 for the small extra spend.

Assuming you want something a bit more capable, then the iO6 represents the best value option. It has many of the most desirable features of the iO range, including the in-handle display. But, it remains relatively affordable and you get the best of both worlds, so to speak.

Whilst the iO10 is the most technically advanced, we don't recommend it. The only difference between the iO9 and the iO10 is the enhanced charging stand and it’s simply not worth that kind of money. 

Monochrome vs colour display of iO7 vs iO8
Black and white display of iO7 (left) vs color display of iO8 (right)

5 of the 9 variants have a display built into the brush handle.

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

Color or not, they operate in the same way and provide extra functionality. For example, you can change the handle language, change the color of the smart ring or even reset the brush.

The biggest benefit is that it makes it much easier to switch between the brushing modes or see which one you have selected.

All the brushes have more cleaning modes than you need

Depending on the model you go for, you have the choice between 2, 3, 4, 5, 6, or 7 brushing modes. 7 is the maximum number of cleaning modes available on any Oral-B brush.

I’ve yet to find anyone who uses them all or any real justification for having so many. The reality is the cleaning results between each are very similar.

For most users, 1 mode, daily clean, is more than satisfactory.

A second, lesser powered mode such as sensitive is a welcome addition for new electric toothbrush users, or those with gum disease or sensitivity.

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.

All modes are designed to be used for 2 minutes. The only exception is tongue clean which is set for 30 seconds.

The table below shows which iO model has which mode. Should you want to learn more about each, do read our Oral-B cleaning modes explained article.

Some models don’t make it clear which cleaning mode you have selected

The iO2, 3 and 4 do not have any labels or icons on the handle to show which mode you have selected. 

The iO5 has backlit icons, without text based names to show which mode is active. 

The Series 6, 7, 8, 9 and 10 will show an icon alongside text on the handle display.

Models that connect via Bluetooth to an app will report the active mode within the on-screen timer.

You can’t change the mode before turning the brush on with the iO2, 3 and 4.

‘Real-time tracking’ varies from one brush to another

Real-time tracking is part of the smart technology offered by the iO series. It works with the Oral-B app on your smartphone to show you a graphic image of how well you are brushing your teeth.

The iO2 and 3 have no Bluetooth connectivity and can’t be connected to the Oral-B smartphone app. Therefore they have no real-time tracking.

The iO Series 4 has Bluetooth and will connect to the app, but the functionality is limited. There is no real-time tracking — the on-screen timer that tells you how long you have brushed for is the main functionality.

The iO5 through to 10 do have real-time tracking.

However, Series 9 and 10 are the only models to offer comprehensive 16-zone tracking. The iO 5, 6, 7 and 8 only have 6 zone tracking.

Oral-B iO Series comparison 3

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. But, how much difference this makes in everyday use is up for debate. To get maximum benefit from it you need to use the app every time you brush.

The 16 tracked zones are as follows:

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

Graphic showing the 6 tracked zones with Oral-B real-time tracking

When only 6 zones are tracked, you can essentially spend all the time cleaning only 1 of the surfaces within that zone and the app will still consider the zone cleaned. 

With 16 zone tracking, dotted zones sit in the center of the on-screen display. As each zone is brushed correctly, that dotted zone disappears until none remain. All the teeth on the large visualization turn white. The extra detail in the tracking can pick up on more specific, but important improvements needed in your brushing routine.

Although the iO10 has 16 zones tracking, the iO Sense stand is configured to give feedback on 6 zones. It has benefits (more on those below) and offers at a glance feedback without a smartphone, but the app provides more meaningful data.

There is no long-term data available that analyzes if apps and real-time tracking do have a beneficial impact compared to someone learning the correct brushing techniques via other means, such as plaque disclosing tablets.

Brush head replacement reminders are implemented differently

A brush head should be replaced after about 3 months. After this, the bristles clean less effectively and are more abrasive on the teeth and gums. There may also be an increased amount of bacterial build up.

All iO models, with the exception of the iO2, have a reminder system built into the app and the brush handle. How this reminder is displayed differs.

The iO3, 4 and iO5 have a yellow light that illuminates in the center of the cleaning mode button. The handle will vibrate too.

Those models with a display will show a notification on the screen. If connected to the Oral-B app, a notification will be displayed here too for compatible models.

Overall, brush head reminders are a feature that are nice-to-have, but not critical. If you’re organized enough you can simply use a recurring calendar reminder. The fact that they are included on each iO model means you don’t need to factor this feature too heavily into your choice of iO brush models. 

Battery life should be similar, but premium models are inconsistent

Oral-B isn't that explicit with their references to expected battery life on these handles. They use phrases such as 2 weeks+ or long lasting battery life.

The vast majority of handles last 17-20 days on average.

Yet, my testing found that 12 days of use is common with the iO9 and I can achieve up to 37 with the iO Series 2.

From opening up the different models, I've seen that whilst most use the same battery, the capacities of some are different. The iO2 has a 600mAh battery compared to the 750mAh in the iO3.

The different motor in the iO2 vs the iO3 goes some way to explain the different usage time. My suspicion is that the displays in the premium models reduce the usage time. This is not helped by the fact that they activate as a result of vibration or movement nearby, thus drawing power from the battery. 

The iO7, 8 and 9 come with a premium magnetic charging stand

The 2, 3, 4, 5 and 6 all come with a standard Oral-B charger. White in color, it has a protuberance on the top that fits into the base of the brush handle.

A 2 pin power adapter is hardwired into it. The adapter supports 110-130v.

Brushes take 12-24 hours to recharge when on this stand.

The iO Series 7, 8 and 9 come with a premium magnetic stand. It’s either white or black.

The 2 different charging stands used by iO brushes
Standard charger (left) vs premium magnetic charger (right)

The round charger has no protuberance. It does have a 2 pin power adapter, and supports 100-240v. It takes up to 3 hours to recharge the brushes on this stand.

Only the iO7, 8, 9 and 10 fit and will charge on this stand.

For me, the fancy charging stand isn’t too big a factor. If bathroom visuals are important to you, maybe the magnetic stand is worth paying for. Otherwise, you can get by just fine with the cheaper stand.

The iO10’s stand is a bit different 

With the iO10, you get an iO Sense charging stand, which is magnetic and charges the brush in up to 3 hours. But, there is extra tech built-in.

You have 6 LEDs and a clock on the front to help encourage even brushing and good coverage of your teeth as you brush.

The idea is you get meaningful feedback on how well you are brushing without having to refer to the smartphone application. 

It’s a nice enough feature, but it increases the cost of the brush. It’s the only difference between the iO9 and iO10 but changes the price by $80, which just isn’t worth it. 

You can get more insight into what it offers in our iO10 review.

Oral-B iO10 with iOSense Smart Charger
iO10's charging stand gives feedback on brushing time or coverage using LEDs

The handles with displays give the best battery feedback

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

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

The iO2, 3, 4 and 5 give feedback via the LED in the power button. It illuminates white most of the time. Only when the charge is around 10% or less does it pulse red.

Those that connect to the Oral-B app will show a percentage level on-screen too.

Oral-B iO Series 8 next to iO9

Only the iO9 and 10's travel cases offer in the case charging

The vast majority of 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.

The iO2 and 3 are the main exceptions though. No case comes supplied with the standard models. But there are variants where this is supplied.

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

iO9 and 10 can be recharged whilst inside their travel case - requires separate power adapter

The iO9 and 10 can hold the handle and 1 brush head only. This is because you can charge the brush inside the case. There is no battery in the case to do this. Instead, you connect the supplied proprietary power adapter.

Whilst all cases are functional, those supplied with the 7, 8, 9 and 10 are higher quality — they are thicker and more durable.

The iO Series handles are quieter than other Oral-B brushes

iO handles are generally quieter in use than non-iO models from Oral-B.

The majority of iO models now operate at a maximum noise level of 64 decibels. 

The 7, 8 and 9 were the first iO models to launch. They registered higher in our testing. Oral-B may have made changes since launch to reduce this and bring it in line with other iO models. We haven’t purchased these models again to check this.

No mention of noise is made in the iO 7, 8 and 9 manual, whereas it is with the others.

The light ring can be changed on all models apart from the iO3

Except for the iO2, all models have a light ring that doubles up as the visible pressure sensor.

All models bard the iO3 allow the color of that ring to be changed. 

You need to use the Oral-B app to change the color.

The iO6-10 does allow the color to be changed via the in-handle display. But, you have fewer color choices than if you navigate to the app.

There is some variance in the colors available

As a general rule, all models are available in black or white. Some are available in other colors too.

Oral-B offers select heads in black as well as white. Black handles are supplied with a black brush head.

White and all other colored handles usually come supplied with a white brush head.

Travel cases are usually white, except for black models.

Charging stands are always white unless you buy the Series 7, 8 or 9, where they are available in black too.

Conclusion: we recommend the iO6

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

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

All of these brushes offer more than what you need.

The iO6 is the best value model.

The iO3 is our recommendation for the most affordable model. Technically the iO2 is, but the pressure sensor and other differences are worth the small premium.

The iO9 has all the tech.

iO models command a price premium, particularly when you factor in replacement brush heads. You don’t need a premium model 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 and it’s worth considering unless you’re set on particular features from the iO range.

Jon, I want to convert from a manual toothbrush and get an oral b electric toothbrush and have narrowed it down. I do not anticipate using or wanting tracking where I brush with any app or my phone. I mainly want a quieter version that has a sensitive feature which all of them have. I have narrowed it down to the Smart 5500 ($100) or Limited ($110). Genius 8000 ($100) or Genius 7500 ($114). Or the IO 6 ($130). Finding decibel levels for each of these to compare is not easy to find, but not sure given you have tested all of them if there is much difference in real life? Another factor is the non IO heads are way cheaper. Also to throw a wrench in there I found a Crest+Oral-B iO Transformational Gum Health Electric Toothbrush System which I think is an IO9 dummied down for $190. For comparison My wife has a Pro1000 and my daughter has the Smart 3000 and I feel like they are quite loud and somewhat rough feeling. Interested to hear your thoughts. Thank you.

Hi Mike.

OK, so the noise of the Smart 5500, Limited, Genius 8000 & Genius 7500 were around 77dB in my testing. The iO6 is around 64dB. So there is a notable difference.

I've not bought or handled the 'Crest+Oral-B iO Transformational Gum Health Electric Toothbrush System' but a quick search suggests maybe it is the iO7 in that bundle.

Given your comments about noice and rough feeling I think the iO6 will be best for you if you are happy to pay the premium for the brush heads. The additonal ~$30 to buy the handle is arguably justifiable for the noise/in handle display/gentle brushing sensation.

To throw a curveball in the mix....

If you are happy to put up with the noise and rougher brushing sensation then the Oral-B Smart 1500 is my top pick normally. It's cheaper and doesn't have the features you don't need. That said, there is a similar dual handled bundle Oral-B are selling at the moment, the Oral-B Smart Clean 360 which is currently ~$70. It's exceptional value for money given you get 2 brush handles and charging stands and tracvel cases. You do too get a more gentle sensitive mode and gum care mode.

This is by far the best review of the Oral B IO models I have seen. It was exactly what I wanted to research and you did all of it for me. Very concise and includes everything I needed to make a decision.
It is great to know that they all have the same motors and heads and you basically just pay for the technology upgrades between models. The IO Genius 8000 is on sale for $99 now at oralb.com but given the noise level of that one I would still rather have the IO versions you reviewed. I do not think I will ever use the app to tell me where I am brushing and if I am doing it right. I just want one that is quieter and not too aggressive on my teeth and gums. I am leaning between the IO 5 or 6. I like that the 5 offers super sensitive mode but like that the 6 has the better mode display.
The only question I have is about the chargers..... Is it worth upgrading to the IO7 for the magnetic charger? Can I just leave my brush on the charger to store it on the counter all the time so I never have to worry about the battery life?
Thanks for the helpful info

JL
Jon Love - Chief tester
April 1, 2024

I don't think it is worth the upgrade to the iO7 for the charger. Maybe for ~$10 but for most it's not worth it. Do you need your brush to charge in 3 hours?
You can happily leave the brush on the charging stand all the time so not to worry about battery life. It will stop charging once the battery is fully charged.

There is argument that it is better for the battery to not always be on the charger and topping up. So, recharging every 10 days or so, when the power is down to about 20% for example. But, theres limited evidence to really say or show its worth worrying too much about.

Why is it that the Series 4 has 500% increased plaque removal along gum-line vs the Series 3's 400%? Since you say they clean all the same

JL
Jon Love - Chief tester
December 19, 2023

I'm not sure where you have seen these specific claims, but usually the difference is based on what study Oral-B is usuing to get these figures. Different studies give different results and thus Oral-B use these to make specific products appear better.
I am not suggesting the evidence isn't there, but sometimes it is not always quite what it seems.

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 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!

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?

JL
Jon Love - Chief tester
December 8, 2021

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.

Jeff
December 12, 2023

Boy howdy are they more cost effective. I was cringing when I paid $3 per brush (the Triumph style), but now I see they can be $7.50 and higher. WOW! I think I'll stick with my old Oral-B.
Question: Why are the iO 7, 8, and 9 so much louder than all the other ones? 64 dB vs 72 dB is a very noticeable difference when the brush is so close to my ears!
Thank you for the helpful information you are providing.
Jeff

JL
Jon Love - Chief tester
December 13, 2023

Hi Jeff.

In our testing, we found the iO7, 8 & 9 to register at 72dB vs the 64 dB of all the other models.

Interestingly the manuals of the iO3-6 all specifically state max dB of 64 too. The other manuals don't too my knowledge.
I believe all the electronics are the same.

The iO7, 8 & 9 were the first models to be designed and launched. It's possible revisions have been made in the other models to address the noise. Hence iO3, 4, 5, 6 & 10 being quieter.
It is too possible a new iO7, 8 or 9 is quieter than the one we tested when they first launched in 2020. We just haven't bought these 3 models again to specifically test the sound.

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

JL
Jon Love - Chief tester
October 20, 2021

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.

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.

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?

JL
Jon Love - Chief tester
March 10, 2021

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.

SK
Sam Khoury
March 10, 2021

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.

SK
Sam Khoury
March 10, 2021

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.

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!!

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.

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.

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

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
