Editor’s Note
Since this review was published, newer models have been released.
The Oral-B Smart 1500 is currently our most recommended brush.
It cleans the teeth well, has dentist recommended features and is good value for money.
Here are some of the current places you can purchase the Smart 1500:
Our best electric toothbrush article contains additional recommendations and advice on choosing a new toothbrush.
A great clean with more tech than you need

The Genius Pro 8000 is amongst the best brushes on the market. It’s packed with features including those dentists recommend.
Capable of providing a great clean of the teeth, the tech can help show you where you can make improvements, but it’s a bit of a clunky setup, with newer models being more user friendly.
Pros
- Cleaning performance
- Smart travel case – stylish & functional protection
- Bluetooth connectivity for pairing with a smartphone via an app
- Position detection – clever concept for real-time tracking
Cons
- 5 cleaning mode icons, but 6 cleaning modes
- Position detection – requires habit change to use
- Smartphone holder – clunky option most won’t want in the bathroom

Which other brushes should I consider?
It will cost, but the newer iO Series 6 is essentially a couple of generations on from the Genius 8000. The result is a more refined daily user experience. You can make improvements in your oral care, if committed.
But, you don’t need all this tech, if you learn how to brush correctly.
The Smart 1500 is a considerably more affordable toothbrush, but it lacks real-time tracking, in favour of the essentials you need.

Design, usability, clean & general use

The mouth is the gateway to your body, through your mouth passes so much. A good oral hygiene routine can really affect you, your health and how you feel.
You probably have had a few occasions where your gums are sore and inflamed, you feel a bit run down and generally want to feel better with a more positive outlook.
You might be surprised how just 2 minutes of thorough cleaning twice a day can impact on this.
Investing in a good toothbrush certainly helps and whilst it does not have to be the Genius Pro 8000, this is one of the best available today.
There is a lot to this toothbrush. Who knew a toothbrush could be so complicated. Let me start by pointing out some key facts and features about the brush so that you understand what exactly the 8000 is offering and how it differs from many other brushes.
The 8000 was one of the best options available to us in the USA, and it still is very good. However, the newer Genius X is better, a more practical implementation of what the Genius 8000 offers.
There are a variety of cleaning modes, 6 in fact, and it comes with a good box contents, pressure sensor, multiple brush heads a travel case and built-in timer.

One feature that is heavily talked about and marketed by Oral-B is their app and the Bluetooth connectivity this brush offers.
It has been made available before but there have been significant improvements in the app and the technology built into the brush to have it work better.
The app uses the front facing camera on your smartphone to track the actual position of the Genius Pro 8000 inside your mouth when in use. It takes this data and displays this on the smartphone screen, giving instant feedback to highlight and direct you to where you have missed and where you need to clean next. It is almost like having a dentist or hygienist looking over your shoulder saying good, bad, brush for longer, you missed a bit.
As you might expect Oral-B know a thing to two about toothbrushes and have conducted many studies, with their Motion Tracking Study showing that up to 80% of people spend insufficient time brushing in at least one zone of their mouth and 60% of people either didn’t brush their back molars at all, or spent insufficient time brushing them, so you can see why the position detection technology exists.
Failing to brush your teeth properly can lead to all sorts of problems. It might start with a bit of swelling and inflammation and discomfort but over time this can get worse and require professional medical attention that can be painful and expensive.
This new brushing system is designed to help coach you and me to brush properly, in real-time.
Version 4.1 is the earliest version of the Oral-B app to support the Genius Pro 8000. The app will run on most Android or iOS devices. And uses Bluetooth on your phone and the Pro 8000 brush to pair. Your smartphone must have Bluetooth 4.0 as a minimum for compatibility.
You can download from iTunes here and Google Play Store here.
The following video demonstrates the pairing process along with how to use the Genius toothbrush:
The app is very comprehensive with lots of options, too many to go through completely in this review. It gives you all you need though to not only effectively brush your teeth, but to log the cleans and motivate you.
In 2018 ‘Gum Protection Technology’ or ‘Gum Guard’ as it is also referred to as was introduced.
Essentially, this is a software update to the smartphone app (available in version 6.0.1 of the app and above) that offers a special brushing journey, specifically designed to help improve your gum health over an 8 week period.
Bleeding gums are usually a sign of gum disease, which in many cases can be treated with a good oral hygiene routine at home.
The app is geared to help reduce and stop the bleeding of gums and help you turn your red, bleeding, sore and puffy gums to a nice healthy pink, bleed free gums.
You run through a series of screens, shown below that collect data and allow you or your dental professional to make custom adjustments to help achieve the end goal.









Naturally, Oral-B recommends selected products to help get the job done, but over the 8 week period the app will monitor, encourage and help you work towards achieving those healthier gums.
Setting up this Gum Guard mode within the app does disable some other cleaning modes, but you can end what Oral-B call a journey at any point if you like.
Your gums might be in good shape, but other areas of the mouth might need attention, this is where the Professional Guidance feature allows you and your dental professional to work together. Actually, share and discuss improvement areas and have your dentist program into the app extra brushing time and adjustments to your cleaning modes in your app.
There are features like integration with your calendar so you can see your day’s agenda, news, tips and tricks, so you stay interested when cleaning your teeth. Although for me, on occasions it can be a bit distracting from you ensuring you brush correctly and you may want to customize the settings to avoid some notifications.
Of course, the big part of this is the Position Detection Technology which uses the smartphone’s camera, the app and the brush to show on screen visually where you have and have not cleaned and shows you how to brush all zones in the mouth evenly and equally. Anyone of any age can use and learn from the feedback it gives.
Whilst a toothbrush plays a vital role in oral hygiene the routine and way in which you clean does too. This app makes it easy to see and represent in real-time just how good, or bad you are doing.
Challenges are presented to you allowing you to obtain a score based on how well you brush and improve your habits. Brush better and for longer and you ate on the road to success. Gain badges for achievements and share socially if you chose.
























If you have perfected your technique you may have less to gain than others, but I was impressed at just how well the app works and monitors you clean, it still had areas where I could improve!
The app is deeper and more intelligent too. You can customize the brush and personal goals through the app gaining more suitable tips and advice along with product suggestions. For example, if you wish to whiten your teeth the app will advise and amend your routine to achieve the goal. You can choose from the Fresh Breath Gum Health, Plaque Fighter, Whitening and Ortho Care journeys.
Online backup is another feature. With an Oral-B account, you can never lose data and even share with compatible services for additional insights and benefits. As the app logs data over the days and weeks, it is impressive to see through the logs how your habits and brushing time changes.
Whilst you need to launch the app each time to use it the brush itself can store the data for up to 20 cleans meaning you do not need to always have the app to hand.
The connection and transfer are fairly reliable and I have yet to run into any real problems.
The app is not designed for or really geared for multiple users. If you share a brush handle, to make the Oral-B app work for multiple users, you need to turn off the automatic syncing in the app settings and each user must use the app in real-time when they brush and have the app installed on different phones. It works, but is not ideal at all.
Now I have spoken about all the magic that is the Oral-B app for tracking the clean, you need to hold your smartphone at face height to actually do the tracking. Easier said than done.
You could hold it in your hand, but unless you have some super power that means you can hold your phone perfectly positioned for 2+ minutes and clean your teeth, then the provided smartphone holder will come in use.

Best described as a smartphone holder you would use in a car and attach to the windscreen, used in the home and attached to a mirror!
It is a more clinical and perhaps suitable in white; more fitting for the bathroom scene. The suction cup will attach to mirrors and in some cases tiles. Do make sure it is secure before mounting your phone! There is a lever to lock it in place and unlock the hold along with a tab on the suction cup to further release the holder.
Whilst the holder has remained attached to my mirror and not fallen, I know many are concerned about it failing and an expensive smartphone being broken as a result.

The universal holder has the Oral-B logo on it and an arm that can be adjusted to fit many smartphones of varying sizes from 58mm wide through to 83mm wide. If you are using a Samsung Galaxy S series or an Apple iPhone 6S Plus even, it will fit. There is then a full 360 degree rotation option. For some phones, the button placement may interfere with the adjustable arms to do consider this when docking the phone.
It is a practical addition and can move with you. That said, you are likely to mount it and leave it as I assume you generally speaking brush your teeth in the same location each time.
The particularly house proud may not like the holder on show, but for the sake of your teeth and oral health let go any reservations you may have about what the neighbors or family members may think about a smartphone holder in the bathroom. I am wondering if there is another solution?
In my bathroom, I ended up with the suction cup being sort of in the middle of the mirror which was a bit annoying, due to my height and the mirror position. There is also the fact that if you share this brush with others, although they may have the app on their phone and may need to change the placement of the suction cup, thus making it cumbersome and a lot of effort.

It is also worth noting, whilst it is perfectly possible to share a brush handle, the handle can not differentiate between 2 users, so your data synced to the app will be wrong.
Even for me, even as someone writing about toothbrushes, I find it hard work and difficult to make set up the smartphone in the holder with the app, a bit of a chore and although it may take 15-30 seconds, that’s around 25% of the time I would spend cleaning my teeth.
It is not to say I have not found a routine, but I have not perfected it and am finding that I may use the app more in the evenings than the morning and probably in total using it 50-60% of the time.
But even with a commitment to use it in the evenings, the app needs to work and to a point it does, but I feel the position detection technology and the overall experience is not there yet that everyone will take the time to use it.
There are silly quirks, like the smartphone holder having full tilt and swivel capabilities, but the phone must be perfectly upright for the position detection to track, making the holder mobility almost redundant.

You need to be almost statute still for the app to track effectively.
I found it unable to accurately track where I was in the mouth. It was close but often registered in the wrong area. I think this was in part by me tilting my head, opening and closing my mouth more or less as I moved around my mouth.
Practice will allow me to get better but how much practice and how ‘still’ should I stay.
Much of this has been addressed with the new Oral-B Genius X however. No camera needed, all the technology is built into the brush handle.
As you brush there are fading blue sections on-screen that do act for encouragement and at times the app gets it right, encouraging you to spend more time here and there with a mix of praise and positive feedback.
I found myself at times, spending more time cleaning my teeth (this is a good thing to a point) to try and ensure I got all areas of the mouth. However, in doing so, due to the app not registering the areas quite correctly, I ended up spending more time in certain areas of the mouth than others. This resulted in the app thinking I had done a splendid job when I know I had not.
For those who know they have bad habits could use this combination for a few weeks to learn, understand and perfect their clean, but I see very few committing to this and using everyday.
Even with my desire to make it work, it has taken over a week to get close and I still don’t find it perfect. From that, I feel that for most the effort for the reward is too high.
This is perhaps not how Oral-B envisaged or planned the usage, but there is only advantages to be gained from using it occasionally than not at all. Even a few times a week it reminds you and helps perfect your brushing habits.
The good news is the brush store your clean history for the last 20 cleans so you can still retain a lot of data even if you do not use the app all that regularly. The best data will be for those who use the app all the time.

If you are to look closely at the Genius Pro 8000 there have been seen some improvements in comparison to the Pro 7000 which it supersedes.
Slimmed down a little in the profile to the older 7000, the Genius has a more uniform cylindrical body, similar to but larger than the handle size found on the Pro 100 and 3000.
Solid and premium feeling in hand the brush is 24cm tall and around 3cm wide and deep and weighs in at 140g.
The battery is fixed internally inside the handle and offers up to 12 days of battery life.
Unlike the Pro 7000 and even the Pro 1000 the Oral-B 8000 is available in Black color only (additional colors introduced October 2018).
The provided brush heads are white in color as is the smartphone holder, yet the smart travel case is Black. Would it not make sense to have it all in Black? If nothing else a color matched brush head?! This seems not to be any trouble for brands like Sonicare.

I think it detracts from the overall design a little.
I understand the smartphone holder being white as typically this is a common color in a bathroom.
Despite this small niggle the plastic and rubber construction of the brush feels and looks good. The plastic is resilient to the water, bacteria, and toothpaste that it will come into contact with.
A fully sealed brush it can be used in the shower, rinsed off under a tap, etc without issue. Avoid complete immersion in water, it’s not designed to survive such treatment.
The front of the brush has become a little busier compared to other brushes, but this is, in my opinion, a step in the right direction. Models like the 3000 have no way of clearly telling you which cleaning mode is active/selected but you can, sort of, with the 8000.
A break in the plastic body makes way for a tall, essentially rounded rectangle shaped panel. Within this is a similarly shaped yet smaller rubber panner in the upper third that has the power button and cleaning mode button.
Below this are icons for the different cleaning modes, well 5 of the 6 available anyway. Daily Clean, the default and go to cleaning mode has no icon. Why?! It is just odd and confusing as it looks like there are only 5 cleaning modes, not the available 6.

Press the power button once to power the brush on and press and hold for 2 seconds to turn the brush off. The button requires a firm push, meaning it is difficult to accidentally power on or off.
To change the cleaning mode it is a case of pressing the cleaning mode button (downward facing arrow) under the power button and continuing to press until the desired cleaning mode is reached and the indicator illuminated. Each cleaning mode is backlit with a white light when selected.

Gone is the blue light as seen on the Pro 7000 and now it is white light. I preferred the blue, but white is probably more appealing to all users in general.
To switch cleaning modes you must have the brush powered on and cannot press the cleaning mode button to cycle through them before powering the brush on. I see why this is but to change mode you need to look at the handle and need to do this before applying toothpaste and water to the brush head.
Models from other brands allow the cleaning mode to be selected and then the brush powered on.
In the lower third of this front panel is a Bluetooth icon, a battery icon made up of 3 bars and then finally the Oral-B and Braun logos.
On the rear of the brush is a contoured rubber grip which assists when holding the brush for grip, especially when wet.
The base of the brush is sealed but has a recess into which the prong on the charging stand fits to charge the brush.
On the neck of the brush is where you find the LED SmartRing which will illuminate red when the pressure sensor in the brush is activated and will at other times (when powered on) shine one of 12 different colors set by you through the Oral-B app.
If using the app at the same time as brushing, the screen on the app will also illuminate red and tell you to reduce the pressure should you apply too much to the teeth.

This sensor looks to reduce and stop gum and tissue abrasions that are caused by excessive pressure application when brushing the teeth. A fairly gentle glide across the tooth surfaces is all that is needed, with some manual brush users applying up to 2 times the amount of required pressure.
The brush will automatically reduce the head speed and stop the pulsation until the pressure is reduced. Triple detection and alerts should quickly make you aware when you are brushing too hard.
There is the pressure sensor light, the sound of the motor and the message within the app to tell you to change that rushing approach.
Although not new to Oral-B toothbrushes, a noteworthy and easily overlooked design feature is the rounded brush head. Small and compact you can generally get the brush head into all the hard to reach areas of the mouth, which is not as possible with some other brush heads shaped differently.
The brush heads provided with the Genius Pro 8000, use an oscillating rotating and pulsating motion as shown in the following animated image.

This is a proprietary technology that helps clean tooth by tooth reaching areas that are often missed.
The dynamic 3D movement helps adapt to your teeth as it oscillates, rotates and pulsates to break up and remove up to 100% more plaque than a manual toothbrush.
3 brush heads are supplied with the Oral-B 8000. They are just 3 or a larger range of available heads. The interchangeable design makes it easy to swap them out every 3 months or when you want to use a specific head for a specific cleaning mode (although any cleaning mode can be used with any brush head).

Remember to replace your brush head at least once every 3 months or 90 days if not sooner. You can have the app remind you of this, or why not set up a scheduled delivery through Amazon?
An Oral-B brush head will fade in color as it ages giving you another visual indicator that it is time to replace the brush head.
The 6 cleaning modes available on the 8000 are:
- Daily Clean
- Gum Care
- Sensitive
- Whitening
- Pro-Clean
- Tongue Cleaner
I cover all of these in more detail in this post on Oral-B cleaning modes.

All these modes, with the exception of Pro Clean are standard cleaning modes found on previous/other Oral-B models, although not all have every mode.
The Pro-Clean mode replaces what was known as Deep Clean mode that is available on the Pro 7000.
Pro-Clean provides an intense clean feeling with 3,000 more movements per minute than the more standard Daily Clean mode.
You can choose any cleaning mode you like based on your preference.
Typically the cleaning modes last for 2 minutes each and this ties in with what is recommended by dentists. There is a built-in timer which has 2 modes, the standard 2 minute or professional.
With the 2 minute timer it signals with a long stuttering sound and a flashing light of the smart ring that the 2 minute brushing time has come to an end.
With the professional mode (came preset out of the box) the quadpacer on the Oral-B genius toothbrush kicks in.
A short stuttering sound and flashing light of the Smart Ring at 30 second intervals takes place to alert you to move to the next quadrant of your mouth. A long stuttering sound and flashing light indicates the end of the professionally recommended 2 minute clean.
The timer memorizes the elapsed brushing time, even when the handle is briefly switched off during brushing. Anything longer than 30 seconds paused and the timer resets
You can change which timer profile you have enabled by following the direction in the manual.

There is no denying my teeth always feel cleaner with an electric toothbrush clean than that of a manual brush and the Genius will remove up to 100% more plaque than a manual brush.
Just as important as actually cleaning twice a day for 2 minutes is how you clean the teeth. Follow this guide for the best approach to deliver the most effective results.
Included in the box with the Genius is a charging stand, but also a molded piece of plastic complete with a lid which offers a home to 4 additional brush heads. This protects them from dirt and dust and vies a safe place to keep them. Ideal if you use different brush heads or have brush heads for different users.

The charging stand fits alongside this brush head storage compartment for a neat arrangement on a shelf or work surface. The charger connects to the socket and supports 110-130v.
When the brush requires a charge the last battery bar within the translucent battery icon on the lower third of the brush handle will flash red. It will then light up when charging.
If the power in the handle is extremely low, the battery will require at least a 30 minute charge.
The travel case included with the Genius Pro 8000 is branded and can be considered smart. Rather than a cheap yet functional piece of molded plastic, the travel case here is much more capable.
Larger than I expected the case is well designed and color matched to the brush. Soft touch material all round, a large plastic release button to open it up with gloss plastic end caps to the case.
Containing a USB port, this case not only allows the 8000 and up to 2 brush heads to be protected during travel, it also allows the brush to be charged in the case.

This means you do not need to take the charging dock with you if you feel you will need to charge your brush whilst traveling.
In the box comes a multi-voltage (100-240v) power adapter which connects to the proprietary port on the case and charges the Genius Pro 8000.
Connect the USB charge cable for your smartphone to it and you can not only charge the brush but your phone too, when the mains power adapter is connected to the case.
You may think why or how silly, but this means if going away you need to take 1 power adapter and a USB cable rather than 2 power adapters and a docking station. Thumbs up all round from us here at Electric Teeth.
If I were to get critical this isn’t a great way to charge your phone up fast, but ideal for overnight and a great reminder to use the Oral-B app (as if you would forget)!
And when you do use the app, the case cover has a clip designed to hold your smartphone in place too! Pretty nifty. If your phone is no thicker than 12mm.
It would have also been great if the case used a more standard Micro USB charger, rather than a proprietary connector. This would mean that if you misplaced your Oral-B power adapter it would be easy to find an alternative. I do also think the 2 pin configuration is misjudged considering it is more likely that you will charge the brush via traditional sockets when traveling than from the standard shaver socket.

I should also be clear in that there is no battery built into the case it will not charge the brush handle unless mains power is connected.
An accessory I loved that comes provided with the Pro 7000 but not the Genius is the Smart Wireless Guide. Essentially a portable clock and timer that shows your cleaning mode, how well you are brushing (via a smiley or sad face and star rating) and how long you have been brushing for.
Powered by 2 AA batteries it could sit on a shelf or attach to a wall with an adhesive pad and was a small unobtrusive addition to the kit that worked well. It does nothing more than what the app does, but I believe a very convenient solution to encourage better cleaning when the app is not in use. Sadly it is not included with the Genius.
As a molded brush with virtually an all in one design, maintenance is not simple on this brush other than a rinse and a wipe. However, it should not really be required. Should something go wrong, there is as standard a 24 month warranty is provided with the Genius Pro 8000. This covers the battery too.

Battery life
Personally, I see battery life to be an important factor when it comes to choosing a toothbrush, preferably I want it to last as long as possible without needing a charge. However, 95% of the time my brush lives at home within close range of the charging stand and there is no reason why it could not be charged more frequently.
You may have a different opinion, but with up to 12 days battery life the Pro 8000 is better than the likes of the Pro 1000 or 3000 by 5 days, but still falls short of the 2-3 week battery life offered by Sonicare brushes.
A clever feature which does save power and potentially assists with the cleaning time is that on a Philips or Colgate brush, the brush motor will switch itself off at the end of the clean whereas a Genius series from Oral B will not do this. Is this because by not turning off encourages longer cleaning sessions? Turning it off automatically would save power and better alert the user to the end of the clean.

If using the standard 2 minute daily clean twice a day, the Genius Pro 8000 will give 24 toothbrushing sessions or 48 minutes of cleaning time.
Using certain modes will deplete the battery faster, whilst modes like the tongue cleaner are shorter and use less power, so the 48 minutes is a guide.
I think irrespective of your viewpoint on battery life Oral-B have tried to cover all bases here.
The built-in battery within the handle of the Oral-B 8000 is of a lithium-ion construction, a newer battery technology than the Nickel Metal Hydride that has been used in previous models.
Giving extended usage time, the battery should also stand the test of time longer as this battery makeup handles repeated charges better.
For those who are still underwhelmed by the life of the battery charging is made fairly easy.
Included in the box is the more traditional charging stand that you can leave the Genius Pro 8000 sat on when not in use if you want. The charging dock itself is white in color and has a small prong on the top which aligns with a recess in the bottom of the brush handle and will charge the brush fully in about 8-12 hours. I tend to leave it on charge overnight. When charging the battery charging icon pulses with a white light.
When power is low the battery status icon will flash and you will likely feel the decrease in brush power. When depleted completely the motor will power down and the battery icon flash red.

Another small criticism is that you never know quite how much power is left, is it 20%, 15%. The battery status icons flashes when low. The flashing helps but a percentage guide would be useful, but I have yet to see a brush that offers this. I would have thought that the partnership with the app would have allowed this.
For the travelers, there is the inclusion of the smart travel case too, which has a proprietary charger but does allow the brush to be charged in the case. That case also has a USB port on it, into which you can connect a USB cable to charge items like your phone. So when traveling you take the charger for the case and just the USB cable for your smartphone and from just one socket you can now charge 2 items.
Personally, I would have preferred it if the charging case itself used a more standard connector like microUSB or USB Type-C, or if the case could charge via a USB port on a computer like Sonicare DiamondClean models do, but maybe I am being a bit picky.The 2 pin adapter on the charger will connect to your normal sockets and supports 110-130v. The charger for the smart travel case supports 100-240v.
To ensure that the battery holds its maximum capacity, at least once every six months, charge the battery fully and then let it discharge until it no longer functions.
Summary of battery life
- 48 minutes of usage time or 12 days usage based on 2 cleans a day
- Oral-B brush with longest battery life
- Battery is built in and not user replaceable
- Can be left on the charger
- Takes about 12 hours to charge fully
- When completely flat at least 30 minutes of charge is required
- Recommended to discharge battery fully every 6 months
- The charging stand included in the box supports 110-130v
- Smart travel case charger works on 100-240 volts
- Battery status icon flashes with a white light when charging and red when battery is very low
- Would be good if you got a percentage (%) of the remaining battery
- No auto-power off to conserve the battery
- Questionable whether a premium brush should offer a better battery life
Price & where to buy
I have included links to buying options here at the start of the review.
In the section below, I discuss the price more generally and in relation to similar products.
The Oral-B Genius 8000 has a recommended retail price of $199–250.
This is similar to the older Pro 7000 which is now available for around $120. I would strongly advise not to pay the full price for the brush. You do not need to be some clever shopper to find it much cheaper.
Just a few weeks after launch is already cheaper by some 30%. I purchased ours for just $165.

About $45 more than the Pro 7000, it is difficult to say this is worth the extra spend for all users. Frequent travelers will find the inclusion of the smart travel case appealing and the design and battery life is better, and for this reason, I rate it as one of the best electric toothbrushes for travel.
Over the coming years, the price will likely drop nearer to the $100 mark but for the foreseeable future, it is unlikely to drop below the $150 unless there is a particular promotion running.
I found that most retailers were a bit above the $165 mark with just a couple asking the full $250.
I don’t think it is worth paying the full $250, the value is not present in my mind.
Just be sure to shop around to make sure you get the deal you are happy with as this is just my opinion.
This brush like every other requires replacement brush heads for each user every 3 months. Replacement heads can be purchased in packs of 2, 3, 4 and 5. The prices vary but are on average around $6-$8 per brush head included. The pack of 3 heads often works out cheapest at about $18-20 per pack.
We like to offer up a figure for what we believe to be an average cost of ownership of this toothbrush.
Using the average cost (based on one user) and ownership over 3 years, the Genius Pro 8000 will cost $242 or just $0.22 per day to own.
If the Genius Pro 8000 was purchased at the full $250 price you would be looking at $327 or $0.30 per day to own.

This price does exclude the cost of water, toothpaste and electric to charge it, but you get a rough idea of what it costs to own the very best electric toothbrush.
There is a good chance the brush will last longer than the 3 year period and using the same brush handle but switching heads with other users in your household will only help bring the cost down and drive more value from it.
If cost is a big factor, the Pro 7000 is a consideration which works out at $190 or $0.17 per day to own.
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.

Reliability & long term use
When spending your hard earned dollars you want to ensure that what you are buying is going to last and you will get the value from it.
I would not be doing you justice if it was not a standard procedure for us to thoroughly test each electric toothbrush I review here at Electric Teeth HQ. The Genius Pro 8000 is no exception.
Weaknesses or vulnerabilities are often noticed from an early stage and on the whole electric toothbrushes from premium brands like Oral-B are well made and reliable.
Of course, some can go wrong, but there are usually covered under warranty.
With years of experience behind them, the Oral-B team have designed the 8000 to be just as good if not better than brushes of the past.
I have studied the Genius and there are no obvious places or reasons for this brush to fail or suffer long term. The Black color rubber does not show the muck and dirt quite like some other models but it does show things like white fluff or dust more obviously than other models.
The Genius is a brush that will be undergoing a long term test with us here at Electric Teeth and should I have any issues or find any reason to question the reliability as I used it over a longer period than I have for the purpose of this review, I will report back and update where necessary.
Generally speaking, the weakest point is the battery. After repeated charges and discharges it can fail and should it, they are not easy to replace. Thankfully the lithium-ion battery technology now used in the 8000 is a step up over the old battery technology and should further improve long term reliability from the internal power source. You should get in the routine of depleting and recharging the battery regularly to reduce the chances of failure.
The introduction of the smart travel case and smartphone holder offer up potential extra failure points, but to date, they have both performed well.
To prolong the life of any brush giving it a rinse and a wipe down to remove grime that builds up is a must.
The included 2 year warranty offers peace of mind should something go wrong.
Conclusion
The Genius Pro 8000 is an excellent toothbrush.
It is not without its faults, but when charging this sort of price you have to be critical and compare it to the competition.
The major criticism that is the way it tracks the brush handle is fixed in the newer iO6.
But, when you factor in price, the 8000 is, without doubt, good value. But, for a few dollars more the premium and more refined DiamodClean Smart is a lovely option.
These things aside, there is no denying that the 3D movement of the brush heads and the power delivery coupled with different cleaning modes and the app help you and me as users achieve our oral health care goals and goes a long way to ensuring our dentist is proud of our efforts.
The Genius Pro 8000 is a flagship model, it is like the Ferrari to the toothbrush world. It has all the bells and whistles, which some may not need or desire.
You can get a perfectly functional brush for a lot less but still gain many of the benefits. See the other options.
If money is not an issue and you want the best or you want the flexibility of travel and to take the time to improve your oral health, you may want to consider the alternatives.

What’s with the “Pro” in the nomenclature? I always thought it was just “Genius 9000” etc.
Is there now a Genius Pro 9000? Was about to pull the trigger on a Genius 9000, I’m in Oz (Australia).
Is there a new revision coming out here soon that I should hold-off for…
Thank-you/BR.
Hi James.
The ‘Pro’ is short for Professional. It is just slightly different naming conventions that Oral-B use across the globe. The Genius Pro 8000 is for the USA and is essentially the Genius 9000 in other places of the world. The Genius 9000 is the best brush from Oral-B. No need to worry, not a new model.
