If it’s within budget, this is the Oral-B brush we’d recommend. Yes, it’s still expensive but it’s in the sweet spot where the best features meet the most reasonable price. 

If you’re in the US, prices are relatively stead. In the UK, we’d advise buying at its regularly discounted price of around £110.

The iO range has Oral-B’s best-ever cleaning performance, and the iO6 has five cleaning modes, a brushing timer and a light-up pressure sensor ring. It’s also app-compatible for real-time brushing feedback.

The main compromises, when compared to more expensive iO models, are the monochrome screen (the iO8 and above have a full colour display) and a more basic charging dock that doesn’t offer fast charging. There are fewer brushing modes as well.

We’re not as keen on the fact that a brush at this price point doesn’t have a USB charging option, and the battery life could be much better. You’ll only get 10 days of use – or less if you brush for longer than two minutes at a time.

If an iO is just too pricey, the Pro 3 3000 has all the features you need to take care of your teeth, as well as a very good brushing performance.

This electric toothbrush has a brushing timer that alerts you every thirty seconds to move onto a new section of your mouth and lets you know when your dentist-approved two-minute brushing session has finished.

It also has a bright red pressure warning light that lets you know if you’re pressing too hard.

Although we think it’s great value, we don’t love everything about it: charging takes a long 12 hours; its battery warning light doesn’t give you much brushing time; and it doesn’t stop after two minutes, so you’ll need to give its inset button a hard press to switch it off. It’s not as quiet in use as an iO either.

If you’re feeling spendy, this is the luxury Oral-B brush we’d recommend. Yes, there are two iO models that are pricier (the iO9 and the iO10) but it doesn’t really get much better than this.

The differences between the iO8 and the iO9 are minor: the iO9 has seven cleaning modes instead of six – but how many do you really need? It also has 3D teeth tracking while you brush, which the iO8 doesn’t, but its real-time brushing feedback is almost as good.

The iO8 has fast charging, a full colour OLED screen, app compatibility, three brushing timer options and a pressure sensor.

As for the negatives, these are common to all Oral-B brushes: there’s no USB charging option and the battery won’t last for two weeks. However, the three-hour fast charge goes some way to mitigating these flaws.

If you want brushing feedback from an app but don’t want to go for an iO (the Genius range has much more affordable replacement brush heads), the Genius X could be for you. 

It claims to be AI-driven, but we think this is pushing it a bit. However, it does feature intelligent position detection technology, so it can tell where in your mouth you’re brushing. If you tend to neglect harder-to-reach areas of your mouth, this brush could put you back on track.

It cleans brilliantly, has six brushing modes and a pressure sensor.

The only issue is that if the handle is shared, and more than one person wants to use the app to keep track of brushing stats, you’ll have to be diligent about taking your phone along to your brushing sessions, as otherwise info can be synced to the wrong account. 

The iO4 is one of the most budget-friendly iO models. If you’re in the US, you also have the option of the iO3, which you may be able to get for less but considering discounts here and there, there’s not a lot in it.

Like all iO brushes, the iO5 comes with a travel case and, like the more budget-friendly iO models, it uses the same charger as classic Oral-B brushes and takes 12 hours to fully charge.

The iO4 has a great brushing performance, a vibration timer, pressure sensor and four brushing modes. Like all iOs that don’t have a screen, it’ll cycle through all the light ring colours in a congratulatory rainbow-hued light show when you brush for two minutes.

There’s no screen and no brushing mode icons on the handle. This, as far as we’re concerned, is the only real snag with buying this model. You’ll have to open the app to check which brushing mode you’re using, unless you can tell by vibration alone.

If this is a sticking point, the iO5 has a panel on the handle that displays symbols for all the brushing modes, so it’s easy to see which one you’re using. At the moment, it’s a better buy in the US than in the UK, where its price is much higher than the iO4.

This brush is one of the priciest iOs, with an eye-watering price tag to match.

It’s slick, feature-packed and slightly over-the-top, with a full-colour OLED screen that greets you in the morning and flashes you a smile if you brush well.

But it also has Oral-B’s best brush tracking technology, seven brushing settings and a light-up pressure sensor that not only tells you when you’re pressing too hard but when you get it just right.

And when it times your brushing session, it provides a countdown timer on the brush handle screen so you can see exactly how long you have left.

Apart from brushing feedback, most of the rest of the app functions feel like filler. But that’s okay because the OLED screen allows you to ditch the app and still enjoy most of its features.

On the negative side, the iO9’s battery life is not as good as some competing brushes at this price point and you’ll be lucky to get more than 12 days of use before it needs to be charged.

If you want a great value Oral-B brush but feel that the handle of the Pro 3 3000 looks a bit slippery and shiny, this is the brush we’d recommend. 

It’s around the same price point, perhaps even a little cheaper. It only has two brushing modes (daily clean and sensitive) instead of three, but you’ll get the same pressure sensor and brushing timer.

It has the same flaws as well. It takes around 12 hours to charge and you’ll only be notified by the battery light right when it’s giving up the ghost.

The iO10 is not available in all countries yet and where it is, it’s still only available at its very high launch price. What’s more, apart from its speckled, “cosmic” design, available in both black and white, it only has one major difference from the iO8 and iO9. And if that’s the feature you want, then you may be happy to pay more for it.

The iO10’s big innovation is its iOsense smart charger: a charging dock which also functions as a digital clock and six-segment brushing timer. It means you can get detailed, real-time brushing feedback without bringing your phone into the bathroom with you. We found this feature useful when we tested the brush but it wasn’t perfectly accurate.

The iO10 also has all the same features as the iO8 and iO9: the colour screen, pressure sensor and all the app features. It has seven brushing modes, real-time brushing feedback in app and it can also charge in its travel case.

These are powerful electric toothbrushes that deliver great cleaning performance, with plenty of brushing modes, a pressure sensor and app support.

The difference between the 8000 and 9000 Series brushes are minor: colour options and additional cleaning modes (the 9000 has a deeper cleaning mode and a tongue care mode).

`As these are slightly older brushes, prices can vary a lot. We’d suggest shopping around and looking for deals before you buy. 

Use the brush with the app and you’ll get feedback on how long you brushed for and if you pressed too hard on your teeth. It also has position detection software, but it’s not as accurate or detailed as Genius X or iO brushes.

As you might expect from its price point, this brush is light on features. However, what makes it harder to recommend is its cleaning performance.

It’s one of the few Oral-B brushes that only oscillates – this is Oral-B’s “2D cleaning system”. Unlike the other brushes in this round-up, it doesn’t use sonic vibrations at all, which seriously impacts its cleaning performance. 

It has a brushing timer, but it lacks a pressure sensor. And there’s no battery light, which makes it hard to tell if it’s charging properly when you set it in its stand.

However, if your budget is tight, this will serve you much better than a manual brush. It’ll ensure you brush for long enough and its oscillation-based cleaning will give your teeth a bit of an extra polish.
