Oclean X Ultra S Smart Toothbrush review: powerful cleaning, clever app and reliable advice

When it comes to the best electric toothbrush market, Philips and Oral-B tend to reign supreme. But over recent years, more and more brands have come to light, including Laifen and SURI which we’ve tested and loved on T3.

More recently, I came across Oclean. Founded in 2017, Oclean is still a relatively new name to the market, but the brand designs and manufactures electric toothbrushes, water flossers and UV sanitising systems. But the product I was most excited about was the Oclean X Ultra S, an electric toothbrush that offers AI-powered advice.

I’ve been trying the Oclean X Ultra S for a month and this is how I’ve got on.

Oclean X Ultra S review: price and availability

The Oclean X Ultra S is £129 / $129.99 and is available to buy at Oclean and select retailers like Amazon and Selfridges. It’s available in black and green colours – I tried the former.

Oclean X Ultra S review: unboxing and set-up

The Oclean X Ultra S arrived in a compact box, and comes with the main toothbrush body, three brush head options, a wireless charger, wall mount and travel case. The three brushes are the Ultra Clean, Ultra Gum and Ultra Whitening heads. I tried the former, but when you download the app, it’ll have you answer questions and will determine which head you need – more on this below.

To set up the Oclean X Ultra S, I charged it fully which took a couple of hours. Once it was charged, I downloaded the Oclean app and connected it to the toothbrush. The process was very simple, as both the app and toothbrush have Wi-Fi, so it only takes a few minutes to connect.

Oclean X Ultra S review: design and features

Measuring 13.8cm x 8.8cm x 22.8cm, the Oclean X Ultra S is a Wi-Fi powered electric toothbrush that offers AI voice guidance and a smart touchscreen. It’s powered by the Oclean Maglev motor that offers 84,000 movements, and the toothbrush claims to have up to 40 days battery life.

The design of the Oclean X Ultra S is simple yet attractive. On the front side of the brush is the smart touchscreen which is halfway down the body, and sits atop the stop/start button. The body also has a Wi-Fi symbol which lights up when it’s connected and it has the Oclean logo towards the bottom. The underside of the Oclean X Ultra S has an LED light around it which lights up when in action.

The touchscreen is easy to use – you simply swipe your finger over it to select the different modes. The screen stays dark until you touch it, and when you do, it shows your statistics at a quick glance before it moves onto the different settings. There are multiple modes available, including Sunrise, Sunset, Whitening, Gumcare and Unlimited Clean, all of which offer different lengths of brush time.

Oclean X Ultra S review: app

As someone who avoids downloading apps as much as possible, I was hesitant to use the Oclean Care+ app and used the Oclean X Ultra S without the app for a couple weeks before downloading it. If you’re like me and don’t like having too many apps on your phone, you can easily use the Oclean X Ultra S without the app – but I have to say, you will be missing out.

The Oclean app is free to download and simple to set up. Once you download it, you input your details, like your name and age, and then the app will ask you specific questions about your oral hygiene. For example, the app asked me what type of teeth I have – whether they were sensitive or if I’d had braces – and what I consume, like coffee or alcohol. From there, the app will recommend the type of brush head to use.

The format of the app is clear and concise and has ‘Health’, ‘Device’ and ‘Me’ sections at the bottom. Health is the section which shows your ‘Brushing Activity Clover’ which displays the times, score and number of times you’ve cleaned that day – this is also shown on the brush’s touchscreen. Health also shows your cleaning coverage and advice at a quick glance, and you can access your health report and analysis from there.

The AI advice section was really useful. I found out that I use too much force while brushing and move my brush too much which isn’t something you need to do with an electric toothbrush – see electric toothbrush vs manual brushing for more details. The health report also went into detail about my gum health and brushing force data, and cleaning trends like duration, pressure and lateral pull. I found the app extremely useful and found myself using it a lot more than I expected.

Oclean X Ultra S review: performance

Before using the Oclean X Ultra S, I had been using a manual toothbrush as my old Philips one had packed itself in. So, I instantly noticed a huge difference to the cleanliness of my mouth, and found that the Oclean X Ultra S worked just as well as my Philips brush, if not better.

The Oclean X Ultra S offers a really deep clean that gets into all the areas of the mouth. The brush head felt nice on the gums and teeth, and I found that the higher intensity levels didn’t have any pain or pressure effects, unlike some other brushes. My mouth felt genuinely clean and fresh after using the Oclean X Ultra S which is what you want from a toothbrush!

I enjoyed using the touchscreen as it’s easy to swipe through to get the different modes you want. I tended to use the Unlimited Clean the most, as well as the Sunrise and Sunset options for the specific times of day. The screen counted down the time and the brush buzzes differently every 30 seconds to let you know how much time has passed, which I appreciated.

The Oclean X Ultra S occasionally talks to you in places which was a bit surprising at the start! If I was brushing too fast, the Oclean X Ultra S would stop and tell me in a strange robotic voice before continuing. I found this really useful for my brushing, and the different sounds also helped indicate what I was doing wrong. The Oclean X Ultra S would occasionally randomly select cycles for me – while I’m sure that has something to do with the AI recommendations, it was a bit annoying at times if I just wanted to do a quick clean after eating something but I was given a four minute cycle.

But the main thing I loved about the Oclean X Ultra S was its battery life. I would always forget to charge my electric toothbrush but the Oclean X Ultra S lasted for weeks on end and once it was low enough to charge, the process was insanely quick. I managed to take it with me on two separate holidays that were weeks apart from each other with no issues!

Oclean X Ultra S review: verdict

The Oclean X Ultra S does exactly what you’d want an electric toothbrush to do and then some. It’s comfortable to hold and travel with, and it has the best battery life of any electric toothbrush that I’ve tried.

The design and the touchscreen really sets the Oclean X Ultra S apart. The data and analysis shown on the brush and app are incredibly helpful and I almost enjoyed being scolded by the Oclean X Ultra S when I brushed too hard! As someone who hates apps, I enjoyed using the Oclean Clean+ app and would encourage other app-phobic people to download it too.

It’s hard to find fault with the Oclean X Ultra S – Oclean might not be as well known as Philips or Oral-B, but it really should be.

Oclean X Ultra S review: alternatives to consider

A good alternative to the Oclean X Ultra S is the Philips Sonicare DiamondClean 9900 Prestige. While the Philips model relies more on the app than the Oclean X Ultra S – due to its lack of touchscreen – the brush also fuzzes differently and pauses to tell you how long you’ve been brushing for and if you’re doing anything wrong.

Another alternative to consider is the Laifen Wave. Described as the ‘iPhone of toothbrushes’, the Laifen Wave comes with multiple brush heads like the Oclean X Ultra S and has a good battery life, lightweight design and powerful oscillations.
