2. Is there another model with these features and that is better value for money?

This is a difficult question to address. The Oral B iO electric toothbrush is a premium model and is priced accordingly. And it is loaded with features that fully justify the price tag.

With that said, there are definitely other electric toothbrush models that offer almost similar functions – but at a much lesser price.

One of them is the overall best Oral B electric toothbrush – the Oral-B Smart 1500. As you’ll see in this Oral B 1500 review, all the features that are widely used by most owners is packaged into an affordable toothbrush.

In a similar fashion, the Philips Sonicare ProtectiveClean 4100 is a great electric toothbrush for a shopper on a smaller budget – but who still wishes to enjoy the benefits of a powerful device like the Oral B iO.

See our Sonicare ProtectiveClean 4100 review for more information.

Among premium electric toothbrush models, the biggest contender for top spot against the Oral B iO electric toothbrush is the Sonicare DiamondClean Smart, which is the top-rated model from Philips Sonicare.

As you’ll see from our Sonicare DiamondClean review, this is an electric toothbrush that is widely accepted as the ULTIMATE device against which any other will be compared – to determine the “best”.

So there are other models that offer good value for money.

If you desire the latest, state of art features and functionality in your electric toothbrush, and have decided that Oral B is a great brand, then the Oral B iO electric toothbrush is an excellent choice.

3. Where to shop for the Oral B iO electric toothbrush?

As with buying any electric toothbrush, you can choose between a retail outlet or store, or order the device online.

Differences Between iO Series Models

As with its other lines, the Oral B iO series has different models – the Series 7 and Series 8 and Series 9 devices. All are similar, but have some differences that may make one or the other more suited to your unique needs and preferences.

Oral B iO review – Series 6 summary

The iO 6 Series toothbrush comes with two color choices and 5 cleaning modes. There’s a travel case and one replacement brush head included in the pack. This is the lowest priced among all iO Series toothbrush models.

Oral B iO review – Series 7 summary

The iO 7 Series electric toothbrush is also available in 2 colors and operates in 5 different modes of cleaning. But along with the travel case, you get 2 replacement brush heads as well as a magnetic charger included in the pack.

The price is higher than the iO 6 Series, but lesser than iO 8 models.

The iO 7C Series is a variation on this theme that throws in an extra brush handle and charger, as well an additional brush head. There’s also a couple of premium travel cases included, for a premium price tag.

The iO 7G Series (with an extra brush head holder, but only 1 replacement brush head), and the iO 7S Series (with 3 replacement brush heads but a basic travel case) are minor tweaks on the above mentioned models – with correspondingly different prices.

Oral B iO review – Series 8 summary

The iO 8 Series electric toothbrush offers a choice between 3 different colors and 6 cleaning modes.

There are 3 replacement brush heads included along with a basic travel case, all at a price midway between the 6 and 7 series.

Oral B iO review – Series 9 summary

Oral B iO review

The iO 9 Series stands out in that it offers 3D tracking functionality. It also runs in 7 different cleaning modes and you can choose from 3 color optionsalabaster white, black onyx, or rose quartz.

There are 4 replacement brush heads thrown into the pack, along with a travel case with an inbuilt charging station. It also costs as much as the most premium iO 7 Series models.

Oral B iO Review : Key Features

Oral B iO review - Series 6, 7, 8 or 9

The key features of an Oral B iO Series electric toothbrush are:

  • choice of cleaning modes (5 to 7)
  • inbuilt timer with quad pacer
  • pressure sensor to avoid damage to sensitive teeth and gums
  • magnetic charging station
  • long lasting battery (2 weeks life on a single charge)
  • powerful motor that runs quietly
  • 3D tracking (for the iO Series 9 models only)

Oral B iO Review : Design & Usability

In contrast to the earlier Oral B models that somehow tend to look a bit cheap and unstylish, the iO Series is classy through and through.

Oral B iO review

The distinctive improvements in design standout to make this a truly premium electric toothbrush. Most features are the same as older models, but just polished up a little differently – but make a big difference.

From the moment you pick up the Oral B iO Series electric toothbrush, the experience is obvious. Cylindrical and smooth, the same brush handle now seems more comfortable, ergonomic and stylish.

An oval panel houses the power button, readily identified by the distinctive icon. Another button, this one with a solid dot, determines the cleaning mode.

Each button is designed to be easy to operate even while brushing. A gentle pressure switches effortlessly from one cleaning mode to another.

Design Improvements

Rubber grips to enhance the usability on older models is no longer a part of the iO Series toothbrushes. What’s sacrificed in security of grip is compensated by the sleek appearance and design elegance that catches the eye and will appeal to users.

Another interesting innovation is how the weight and center of gravity of the brush handle is distributed so that it will not roll off a bathroom counter when placed on its side.

A clear ring panel is the pressure sensor, which lights up if you press too hard on the teeth while cleaning.

A flat base allows the toothbrush to be placed vertically on a counter. The shaft projects from the handle, onto which the replacement brush head simply snaps on.

One minor drawback is a slim gap remains between the head and handle even after the head is securely fastened.

iO Ultimate Clean brush heads come in matching colors to the handle. These heads are small and round for better reach and more effective cleaning.

Oral B iO review - Replacement brush heads

Oral B iO Series brush heads are not cross-compatible with other models. This means CrossAction, UltraThin or other brush heads will not fit an iO Series brush.

Another brush head is the Gentle Care model that’s specially designed for sensitive teeth and gums.

Oral B iO review - Brush heads

Indicator bristles are a part of these new brush heads. They let you know when it is time to replace a worn out head. Over the typical 3 month lifespan of a new brush head, the blue color of these bristles wears off.

In addition, if the bristles splay or fray, you should replace the brush head earlier.

The smartphone app that connects via Bluetooth can also be programmed to remind you when it is time for a replacement.

Oral B iO Review : Performance

Brushing with an Oral B iO Series electric toothbrush is a unique experience. The cleaning action is gentler than with other models, but is extremely effective at removing plaque and cleaning your teeth.

Brushing Modes

The device operates in many (or all) of 7 separate cleaning modes.

  • Daily Clean is the most frequently used regular mode.
  • Sensitive is a gentler mode to avoid injury to gums and teeth.
  • Supersensitive is even more gentle.
  • Whiten is an intense mode to remove stains.
  • Intense is even more forceful – and removes plaque.
  • Gum Care massages infected gums, relieving pain
  • Tongue Clean is to keep your tongue free of debris

Most users have a single preference that will most often be used. The others are more like options for special needs, and used only on rare occasions.

Oral B iO electric toothbrush review

Daily Clean is the mode many people will use by default, and is extremely effective for brushing teeth.

In addition to the nature of cleaning, each mode is also pre-programmed to run for differing periods. So an Intense cleaning session lasts 3 minutes rather than the regular 2 minute cycle with most other modes.

The noise level while brushing is noticeably lower. This is due to a patented frictionless magnetic drive technology that powers the brush head. For experienced Oral B electric toothbrush users, this will feel refreshingly different.

The cleaning effect of the Oral B iO electric toothbrush also happens through micro vibrations.

These are set up in the brush head through the magnetic drive that powers the device. It conveys motion from the handle to the bristles, which then gently vibrate to generate a cleaning effect.

Timer and Quad Pacer

Teeth whitening and plaque removal are enhanced by the inbuilt timer which ensures adequate brushing. Dentists recommend brushing for at least two minutes in each session. The timer ensures that you won’t stop earlier.

A quad pacer further guides you to switch from one quadrant to the next after 30 seconds. This makes sure that all parts of your mouth are equally cleaned, without overlooking any quadrant.

As you move the toothbrush from the upper right to left quadrants, and then to the lower left and right quadrants, all the teeth are cleaned effectively. The quad pacer stutters to indicate that it is time to move to another quadrant.

If you prefer brushing for a longer duration, these intervals can be reprogrammed using the smartphone app. In models of the Oral B iO Series electric toothbrush with 3D tracking and AI recognition, this has been shown to enhance cleaning.

When you’ve finished brushing, the display screen even lights up with a smiling face emoji!

Pressure Sensor

The Oral B iO Series electric toothbrushes have inbuilt pressure sensors. These constantly monitor your brushing sessions to detect whenever you press too hard.

Something which is unique to this ‘Smart’ pressure sensor is that it can also recognize when you are not applying enough pressure for adequate cleaning.

Oral B iO review

So where other models will notify you when you press down too hard, the Oral B iO Series will also let you know that you’re not applying enough pressure to clean your teeth adequately!

The LED ring around the neck of the brush handle glows green when you are pressing down just enough – and red to warn you about too much pressure, or too little.

Whenever the sensor detects too much pressure, it will automatically reduce motor power and slow down until you ease off. This helps protect against damage to diseased gums and sensitive teeth.

One minor annoyance is that the glow from the warning LED isn’t always easily noticed. Unless you’re brushing in front of a mirror, you may miss the glow completely. And there is no matching noise alarm to draw your attention to it.

Oral B iO Review : Bluetooth Connectivity

A benefit of premium electric toothbrush models like the Oral B iO Series is the Bluetooth wireless connectivity. When synched with a smartphone app, you can monitor several aspects of your brushing through technology.

The app runs on both Android and iOs phones. It interacts with a sensor in the brush handle and data is transferred wirelessly. You can view in real time or store it for later retrieval and analysis.

It is easy to pair the two devices. You can make any adjustments using the app on your smartphone. When your phone is within range, all information about brushing sessions is stored securely.

The model boasts of an improved artificial intelligence (AI) component of the smartphone app.

As you brush, an image of your mouth lights up on the app once you finish with a quadrant. This feedback helps you modify the way you brush and avoid overlooking any areas.

DiamondClean App - Oral B iO review

Added features such as a scoring system help you know how well you’ve done. And a comparative analysis against past performance lets you see if you’ve been slipping lately.

However, the truth of the matter is that this functionality is purely optional. You’ll get great value from the Oral B iO Series electric toothbrush even without using the smart features at all.

Oral B iO Review : Travel Case

Oral B iO9 Travel Case - Oral B iO review

The toothbrush comes with a handy travel case. Some models have a basic travel case. Others include a premium case with inbuilt recharging capability.

While the travel case is functional, it doesn’t quite feel as classy as the toothbrush does. Neither is it as sturdy as one might wish. While only an accessory, and adequately water proof and protective, it still detracts a little from the premium nature of the device.

The hard plastic case is large enough to hold the brush handle and one replacement brush head. The Power2Go case allows recharging of the battery while you store the electric toothbrush inside it.

A power cable attaches the case to an electrical outlet for charging purposes. An electrical adapter is necessary, making it a bit clunkier and unwieldy.

Oral B iO Review : Battery Life

Battery life has always been a weak point with Oral B electric toothbrushes.

Philips Sonicare models regularly deliver 3 weeks or longer on a single charge. But Oral B electric toothbrushes seldom last longer than 14 days on a full charge.

The Oral B iO Series electric toothbrush is no different.

The manufacturer advertises 2+ weeks of regular use on a full charge. And the Oral B iO electric toothbrush delivers on this promise.

For brushing on the most popular Daily Clean mode, which is what most users do, a single recharge will last for at least 14 days, and reportedly upto 6 full weeks.

This is adequate for most typical users. Even while you travel, it is unlikely you’ll be in a position where you cannot recharge once in a while.

The brush handle houses a lithium ion rechargeable battery. You can recharge it with the magnetic no-contact charging station. It takes around 4 hours to fully recharge, but you can leave the device on the stand for as long as you wish.

A cord of 1.2 meters length is provided to connect the station to a power outlet. An LED indicator on the battery handle shows the level of battery charge.

Many other electric toothbrush models have to recharge overnight. So this becomes a serious advantage for travellers who spend only short periods in a room or with access to charging facilities.

A warning that the battery is running out comes in the form of a pulsing red glow from the light ring. While recharging, this ring pulses slowly until the battery is fully charged.

The Oral B iO toothbrush can also be recharged inside the Power2Go travel case attached to a power adaptor. A full recharge takes six hours.

Oral B iO Review : Where To Buy It?

Buy It Now From Amazon

As mentioned earlier in this Oral B iO review, you can purchase this electric toothbrush online, or at a retail outlet like Walmart, Target, Best Buy or Walgreens.

The higher price of this premium electric toothbrush makes some interested buyers hesitate.

But then, it is a top-of-the-line model with several advanced features and technology. So it offers excellent value for money, even at a higher price.

Oral B iO review - Series 9

It also compares attractively with the Philips Sonicare DiamondClean Smart electric toothbrush.

It is widely acknowledged that the DiamondClean is the best premium electric toothbrush. And this Oral B iO Series toothbrush is of comparable value – at a similar price.

By shopping online at an e-commerce portal like Amazon.com, you can enjoy the advantage of having home delivery right at your doorstep. In addition, you will often be eligible for special offers and discount deals.

Surprisingly, you’ll often find the discounted price for an Oral B iO Series 9 toothbrush only slightly more than what you’ll pay for a Series 7 or Series 8 model.

So it makes sense to splurge just a little bit extra – to enjoy all the advantages of the absolutely state of art premium model.
