The Genius 8000 included in this comparison has been improved upon. The new model is called the Genius X. It is, for most a better purchase.
It is more similarly featured to the DiamondClean Smart from Sonicare, which in itself is an upgrade over the DiamondClean featured below.
There is only a minimal price premium for these newer and more feature rich models.
We encourage you to look at our Oral-B Genius X vs Sonicare DiamondClean Smart for further information.
Which one would we choose?
The DiamondClean is the smarter looking brush, but the style and benefits it offers are not great enough to consider it over Oral-B’s flagship electric toothbrush the Genius Pro 8000.
With so many features, the Genius has more than most of us needs, but it shows innovation and will appeal to those who want to take their oral healthcare routine to the next level.

Detailed comparison: what’s the difference between the Oral-B Pro 8000 and the Sonicare DiamondClean?
Of all the different electric toothbrushes that are available today, these are amongst 2 of the most highly regarded.
Manufactured by the leading brands within the dental healthcare space, neither are bad brushes.
You may well be attracted to one more than the other and that is fine.
However, in this article, I will look in detail at how the 2 compare for you to be able to make an informed decision on which is right for you.
Starting with the design and the way they look. Whilst similar, the DiamondClean from Sonicare is certainly the more minimal and arguably the better looking of the 2.
Physically, here is how they shape up.
- Height (with head) – 24cm
- Width – 2.7cm
- Thickness – 3.2cm
- Weight (with head) – 140g
- Height (with head) – 25.5cm
- Width – 2.7cm
- Thickness – 2.8cm
- Weight (with head) – 142g
There isn’t a great deal of difference between these 2 handles in their overall size and weight, but the 8000 is the slightly chunkier unit and feels so in hand.
However, I actually think the 8000 is easier to grip onto.
Both are cylindrical in shape, but the premium looking DiamondClean has a matte style paint finish, whereas the 8000 has an extensive amount of rubber grip on the rear of the handle for a more secure hold.
The DiamondClean isn’t going to slip away, but there is extra reassurance with the Oral-B.
Sonicare’s DiamondClean has just a single concave power button on the front of the brush handle.
There are a few icons for the cleaning modes and battery icon that light up when powered on, but when switched off, they appear to disappear into the handle.
Minimal is one word I could use to describe the design.
Available in 5 different colors, you can get the DiamondClean in White, Black, Pink, Rose Gold and Amethyst.
The Genius Pro 8000 is certainly busier and feels more functional.
On the front of the 8000 is a convex power button, a separate cleaning mode button, icons for the cleaning modes and battery.
There is the LED SmartRing around the neck of the handle (more on that shortly).
On the rear is the aforementioned large rubber grip.
The base of the brush has a recess for the charging stand, something that the DiamondClean does not have.
The 8000 did come in just a Black color option only and the interchangeable brush heads are White in color, but in 2018, White, Rose Gold and Orchid Purple were added as color options.
White tends to be the default, but a neat touch with the DiamondClean is that there are too Black colored head available which helps with the styling somewhat.
Where many brushes have just 1 cleaning mode, the Genius 8000 has 6.
They are Daily Clean, Gum Care, Sensitive, Whitening, Deep Clean and Tongue Cleaning.
Sonicare’s DiamondClean, on the other hand, has 5. They are Clean, White, Deep Clean, Gum Care and Sensitive.
The obvious omission on the DiamondClean is the Tongue cleaning mode, but to be honest it’s not a big deal.
On the DiamondClean, the mode is selected by pressing the power button and cycling through until the desired mode is active.
The mode is shown on the brush handle and lit up thanks to a White light.
The Genius Pro has a dedicated button for changing the cleaning modes.
It has icons, instead of the actual cleaning mode names on the handle. Weirdly has only 5 icons despite 6 cleaning modes. It does not have a mode for the default ‘Daily Clean’ mode.
Any of these modes use the speed and power of the internal brush motors in different ways.
Some modes will use more or less power to create more invigorating or more stimulating cleans.
Considering the brushing technology just for a moment, the DiamondClean uses Sonic technology to deliver up to 31,000 movements per minute to the bristles on the brush head.
Oral-B, on the other hand, uses what they call a 3D motion.
It comprises of oscillating, rotating and pulsating bristles to deliver the clean to the teeth and gums.
With the 8000, that means up to 10,5000 oscillations and 48,000 pulsations per minute.
This cleaning motion is delivered through the brush head.
Both models come with 3 interchangeable heads in the box.
These heads pull off and slide onto the brush handle.
They can be changed as frequently as you like, but all heads should be replaced with new ones after 3 months use.
Sonicare and Oral-B offer several different styles of brush head. The idea behind each head is to achieve different cleaning results. These can work particularly well with select cleaning modes.
Some have softer bristles, whilst others are firmer. Some have short, whilst others have long bristles and in some instances, the bristles are even angled.
All will provide a generally good overall clean, but a head designed for Whitening is likely to work best with a ‘Whitening’ cleaning mode.
The 8000 comes with 1 x CrossAction, 1 x 3D White and 1 x Sensitive, whilst the DiamondClean comes with 1 x AdaptiveClean, 1 x DiamondClean Standard and 1 x InterCare Standard.
Both brushes clean well. My mouth felt refreshed and clean after each use and to say one is better than the other is not easy. Comparable for the most part.
The small round brush heads on offer from Oral-B are my preference. They are easier to move about and in particular, reach the backs of the teeth and mouth.
The DiamondClean is the quieter of the 2 brushes if noise is important to you.
In favor of the 8000 to, is the brush head storage compartment that comes provided.
Clipping around the charging stand, it provides a home for up to 4 brush heads, under the lid which is in place to protect them from unwanted splashes.
There is no place to store the additional Sonicare brush heads that come in the box.
Built into the brush handles are rechargeable batteries.
These are Lithium-Ion batteries sealed inside.
The DiamondClean offers a very respectable 21 days of battery life based on 1 user, brushing twice a day for 2 minutes.
12 days usage on the Genius 8000 is poor in comparison.
Both do of course come with charging stands, but unusually both too come with cases that allow in case charging.
The Pro 8000 has what I would consider to be a more conventional charging stand.
White in color, the plastic unit has a small profile and sits on a countertop, with the brush handle sitting directly on the top of the stand.
A prong on the stand fits into the base of the brush handle to charge.
Connected into the stand is a power cable, with 2 pin US power adapter.
The stand supports voltages of 110-130v.
Compare this to the DiamondClean and its charging stand supports 100-240v, making it better for travelers.
Unlike the 8000, the DiamondClean has a charging glass.
Like something you might drink from, this glass sits on top of a plate that the power cable is connected too.
The brush then sits in the glass at an angle.
Stylish, premium and different are how I would describe this.
It takes up more space but looks the part.
Both come with premium travel cases that hold the brush handle and up to 2 brush heads.
By connecting a cable, both brushes can be charged inside the case, but this is where things get a little different.
The DiamondClean comes with a USB to MicroUSB cable that connects to a USB socket on a computer or plug and charges the brush in the case.
Oral-B’s solution is a proprietary plug adapter, that supports 100-240v (good for traveling).
This makes Oral-B’s solution a bit bulkier.
However, the Oral-B case also has a USB port on it.
Connect your smartphones USB cable to this and providing the mains adapter is connected to the charging case, it can charge the brush and the phone at the same time.
Sometimes it is the small details that set brushes apart and here are a few details on how these brushes differ further.
The DiamondClean has a feature called ‘Easy-Start’.
When powered on, providing the brush remains powered for 1 minute, the brush will gradually increase the brushing power over 14 cleans. This makes for a more gentle introduction to the power that this brush offers.
The brush will too automatically turn itself off at the end of a cleaning cycle, whereas the 8000 requires the press of a button.
Around the neck of the Pro 8000 is what is known as an LED SmartRing.
Lighting up 1 of 12 colors, that you can set, it doubles up as a pressure sensor.
Apply too much pressure when brushing and the ring will light up Red to alert you to this fact. The light will only go out when the pressure has been relieved.
Brushing too hard can damage the teeth and gums and such helps avoid this.
Perhaps the killer difference between these 2 models is the Bluetooth connectivity that the 8000 offers.
For a detailed explanation of how it works, check out the full written review that is available.
In summary, a free app can be downloaded onto an Android or iOS device and the brush can communicate with it.
The brush transfers real-time data to the app for feedback and performance logging.
It allows the user to understand how they brush and what they can do to improve.
It is like having a dentist in the room with you, particularly when you bear in mind that the Genius Pro 8000 has something known as Position Detection Technology.
It uses the front facing camera of your smartphone, to track the position of the brush in your mouth.
Provided in the box is a suction cup mount, into which the smartphone can sit.
Once aligned the app tracks your brushing and gives even more feedback and tips for improvement.
Clever it is, for many, it is a lot of hassle and not something they want to consider.
Ignoring the position detection, the app is still very clever and useful and can really improve your brushing technique, whilst helping engage you more when brushing.
The app allows for specific customizations and journeys to be set.
As a result of some of the extra in box contents and Bluetooth technology you would think the Genius 8000 is the more expensive, but actually it is the DiamondClean that costs more to buy.
The 8000 has a suggested $275 retail price compared to the $220 of the DiamondClean, but the 8000 sells closer to $170 compared to the $190 of the DiamondClean. More detail and explanation on this shortly.
Naturally, there are similarities to which I will just mention.
Both come with a 2 minute timer and pacer built-in, that help you brush for the right amount of time.
A battery status indicator is available on both to give some feedback on remaining power.
Both have water resistant brush handles and come with a 2 year warranty.
Both have a travel cases with built-in charging as mentioned previously as well as the similar cleaning modes they share.
We have covered the cleaning modes of both manufacturers in the following posts:
Does one clean better than the other?
Both brushes left my mouth feeling clean and fresh.
Slightly different approaches they both have to cleaning the teeth, the smaller round brush head on offer from Oral-B is my overall preference.
Able to more easily reach the back teeth, the small head feels more maneuverable.
But in truth, they are so closely matched.
My hands-on testing has been in no way scientific.
There are studies that promote the efficiency of plaque removal in both Sonicare and Oral-B brushes, but this is typically in comparison to a manual brush.
Studies have suggested that the small round brush head is better, but there are a number of variables here, the biggest being how people brush and how long for.
In day to day life, improving the amount of time you brush for and ensuring your technique is correct are going to bring the biggest wins over opting between either of these brushes.
With that said, there is a very strong and valid argument that the Pro 8000 can ensure you clean your teeth better, because of the position detection and Bluetooth it offers.
Real-time feedback and advice on brushing for the right amount of time, you can be helped to make noticeable improvements in your oral health.
Is one better priced than the other?
Yes, most of the time, the Genius 8000 is the cheaper of the 2 brushes.
Whilst it might seem a little odd, the Genius Pro has a $275 suggested retail price compared to the $220 of the DiamondClean.
However, the 8000 tends to sell for around $170 and the DiamondClean nearer $190.
Oral-B tends to be sold more frequently at larger discounts. I think this is to help encourage the purchase…
Prices are though always subject to change and vary from one seller to the next.
Brush heads also need to be factored into the cost and an Oral-B head will work out at around $5 each compared to the $8 of the Sonicare heads.
Considering the cost of ownership, including replacing the brush heads over a 3 year period brings the daily ownership cost of the 8000 to around $0.20 whilst the DiamondClean will come in around $0.25.
You may indeed find that one is price better than the other or there is an even greater price difference.
In many respects, I believe the 8000 is worth about $20 more than the DiamondClean for the Bluetooth connectivity on its own, but your opinion may differ.
Hopefully, you can take the facts presented here to help make a sensible choice for you.
Whatever you do, buy the brush you feel is the best fit for you and that you can afford.
If you want more cost effective options, they certainly exist, but you might have to forgo some of the luxuries these 2 models offer.
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.
I would actually buy either of these brushes.
The DiamondClean certainly wins for the styling and battery life and I think regular travelers will be more appreciative of what the DiamondClean offers here.
But, my first choice would the Oral-B Genius 8000.
It offers a lot of features for the money.
The Bluetooth connectivity and position detection features are innovative, even if a bit fiddly at times.
Storage space for the spare brush heads, the cheaper ownership cost, and the more grippy design are what appeals.
Ultimately, whatever brush you decide upon, it is you who needs to make the decision; but do so based on which is best for your needs or that of the end user.
Only pay the price you are happy with and do not be led into buying something if it is not right.
Hopefully, I have presented the facts and made the whole decision process that little bit easier.
