Oclean X Ultra S: Two-minute review
I’d been reading about Oclean’s toothbrushes for a while and was impressed at how popular the brand had become in some markets in a short period of time. We already consider the Oclean X Pro to be one of the best electric toothbrushes, so I was rather excited when, in November 2024, the Oclean X Ultra S finally arrived in Australia, where I am based, after being released in the US in April 2024.
The Oclean X Ultra S is a sonic electric toothbrush that boasts some seriously smart features, including leverage bone-conduction technology to provide verbal feedback in real time to help you brush correctly. I’ve been using it since its Australian release late last year and there’s hardly been a day when I haven’t been scolded for doing something wrong.
What I mean by ‘scolded’ is that the voice alerts sound like a 4- or 5-year-old child telling you off. You’ll hear feedback like “over pressure” suddenly pipe up in your ear or, as has happened to me a few times, “hold the brush at a 45º angle”. I mean, you can’t exactly measure that angle while you’re brushing, can you? While I didn’t get scolded for brushing too quickly, there is a prompt for that too. The most common verbal feedback from the X Ultra S is to “switch area” every 30 seconds.
Despite sounding like a petulant child sometimes, I think the verbal feedback is helpful as I found it improved my brushing habits over time, although understanding what the voice is telling you to do isn’t always clear. It took me a couple of times to realize I was being told to hold the brush a certain way (at a 45º angle), and even the “switch area” prompt can occasionally sound a little incoherent over the brush’s buzzing. I would have preferred the voice prompts to be a touch clearer, but I’m really glad it’s not loud.
If you happen to live in a crowded house (or are traveling), people around you will barely know you’re being told off for not brushing particularly well. A few weeks after I began testing the Oclean X Ultra S, I traveled overseas for a 4-week family holiday and no one heard a thing when standing about two feet away from me. In fact, as a sonic toothbrush, the X Ultra S isn’t loud – the motor, despite delivering up to 84,000 movements per minute, doesn’t buzz above 45dB. To put that into perspective, that’s about how loud a library would get.
Brushing data is available in (gory) detail within the Oclean Care+ smartphone app. The toothbrush tracks 8 zones by dividing the oral cavity into 4 areas and counting the inner and outer sides of your pearly whites separately. It doesn’t, however, track the biting surfaces of your molars and premolars. Not only are you presented with a clover-shaped diagram to indicate your brushing score, number of times you’ve brushed that day and for how long, but a 3D movable denture diagram shows you how well you’ve done each session. You are also provided with information on how much excessive pressure you might have used or if there was any lateral movement.

In fact, some of this information will be displayed on the bright color touchscreen on the brush itself, including the clover. This display comes on automatically as soon as you pick up the brush from its charging base or travel case, displaying a default mode based on the time of day – Sunrise Soothing in the morning or Sunset Clearout at night. A total of 6 modes are saved on the brush, including the so-called Exclusive Mode that you can select on the app from a choice of 14 (yes, there are a lot of brushing modes here!). You can even set up your own custom brushing mode if you want via the app and have it saved on the brush. Swiping downward on the side of the touchscreen will let you cycle through the 6 saved options.
The Oclean X Ultra S connects to the app via both Wi-Fi and Bluetooth, with a remarkably easy setup. While traveling, the brush can save up to 7 days of cleaning data, then transfer this information to the app when it’s back within the original Wi-Fi network. I was away for a total of 3.5 weeks on an overseas trip during my testing period and, sadly, wasn’t able to transfer the early brushing data to the app, but the last week of travel is visible on the app. Incidentally, this information can also be sent to the Apple Health app if you happen to be an iPhone user.

While it comes with a small, round charging base that also doubles as its stand, there’s even a magnetic wall mount with a double-sided adhesive pad on it. Oclean says there’s wireless charging capabilities here but that didn’t work for me and, to be absolutely honest, I didn’t miss the feature at all – it seems rather superfluous to me when it has an impressive battery life of up to 40 days.
Admittedly, this remarkably long battery life will only be possible if you are brushing twice a day for just the recommended 2-minute session each, although I think the Oclean X Ultra S is capable of going longer. At the end of my 26-day overseas trip, the X Ultra S dropped down to 40% battery from a full charge, and that’s using the Unlimited Clean mode that let me brush for over two minutes each time (my average was 4 minutes). There are other brushes that offer similar battery life too, but I am yet to see a travel case that can charge the brush while you’re away.

While it does seem to be relatively fragile compared to some of the travel cases that ship with say, Philips Sonicare and Oral-B electric toothbrushes, the Oclean X Ultra S has a case that looks premium and well made. Importantly, it has a USB-C port that can actually top up the toothbrush – something you’d be hard pressed to find with other popular brands. The case also stores two brush heads.
The X Ultra S comes with three replaceable brush heads in the box, each one catering to a different type of clean, like gum sensitivity or whitening. They look like any other sonic brush head, and the design of the brush itself isn’t anything remarkable. However, the color touchscreen is bright and looks rather smart when it’s lit up. It’s capable of displaying festive greetings and showing you the weather. Even the light around the bottom of the brush, which goes from white to red when you’ve exerted too much pressure, adds to the brush’s aesthetic.
All in all, the Oclean X Ultra S is one of the best electric toothbrushes I’ve used – available in Sage Green and Black colorways, it cleans really well in various modes and is arguably the smartest electric toothbrush yet. Perhaps a little too smart, because my only (tiny) issue with the brush is how the verbal feedback sounds – like a child scolding you. Other than that, this is a toothbrush you could definitely… well, sink your teeth into, but maybe consider buying it when it’s discounted.
Oclean X Ultra S review: price & availability
- Announced at CES (January) 2024; released April 2024 in the US
- Available to buy now in the US and Australia; unavailable in the UK
- List price of $129.99 / AU$449.95
As mentioned earlier in this review, the Oclean X Ultra S made its debut in January 2024 at the CES tech trade show and quickly made headlines as the only talking electric toothbrush. It was subsequently released in the US in April 2024, then made its way to Australia in November 2024. While it officially hasn’t been released in the UK, it may be possible to find it on Amazon but being shipped and sold by third-party resellers.
The Oclean X Ultra S will set you back $129.99 in the US and a whopping AU$449.95 in Australia, which is a much higher pricepoint as compared to other markets, even taking taxes into consideration. However, the X Ultra S can be had for half its Aussie price during major sales (which it was during Black Friday 2024, just days after its release Down Under).
If you’re in the UK, I’ve seen it listed online from anywhere between £93 and £219.99 at third-party retailers. UK customers who would love to try an Oclean brush can opt for the X Pro Elite instead, which has a list price starting from £69.90.
Given its various smart features and its build quality, I think the Oclean X Ultra S is absolutely worth considering if you’d like to stop using a manual brush or are keen to upgrade to a new electric one. Just keep in mind that it might take you a while to get used to the verbal prompts – if you can be patient, you’ll definitely see an improvement in your brushing habits.

Should I buy the Oclean X Ultra S?

Also consider
If you aren’t sold on the Oclean X Ultra S or are looking for something different, below are a couple of options to consider – one is an oscillating toothbrush while the other is a sonic alternative.
How I tested the Oclean X Ultra S
- Used for two months daily, twice a day
- Testing period included a 26-day overseas trip without the charging base
- Tried different brushing modes and brush heads
I swapped out my Oral-B oscillating toothbrush for the Oclean X Ultra S in November 2024, soon after its release to the Australian market (I am Sydney-based). I’ve used it twice a day since (and will continue to do so for the foreseeable future), trying out different brushing modes already available in the app and trying to set up my own custom mode. It took me a few sessions to realize that the maximum voice feedback comes via the Exclusive Modes and, for me, that was what helped improve my brushing habits over time.
A planned overseas holiday about three weeks after I began testing the Oclean X Ultra S was an excellent chance to test its claimed battery life. I didn’t carry its charging stand and, although I knew I could use the travel case with any USB-C cable to top up the brush, I didn’t have the need to.
I’ve been using different electric toothbrushes over the years – both sonic and oscillating – and have used this knowledge to rate the Oclean X Ultra S.
