Oclean X Ultra S Review: A Toothbrush That Cleans Brilliantly but Talks Too Much

Oclean X Ultra S Review

Smart toothbrushes keep trying to turn hygiene into a hobby. Most of the time, that ambition lands somewhere between “harmless” and “why does my bathroom need firmware updates?” The Oclean X Ultra S is one of the bolder entries in the category, pairing serious sonic power with a touchscreen, app-driven brushing analytics, and real-time voice guidance.

After using it, the core verdict is simple: the cleaning performance is legitimately good. The rest of the experience is a negotiation between useful feedback and nagging, especially when the brush insists on yelling at me about brushing pressure when the real issue is likely an overly sensitive sensor.

What we like

Pros

• Excellent “just-left-the-dentist” clean feeling
• Strong brushing structure with timed sessions and pacing cues
• On-brush visual feedback and zone tracking can reinforce coverage habits
• Long battery life and travel-friendly charging case

The cleaning results stand out. Oclean’s Maglev 3.0 motor and TurboClean system deliver a powerful, stable feel that makes plaque removal feel decisive rather than cosmetic, with the brush rated up to 84,000 movements per minute.  The immediate payoff is the sensation that teeth are actually polished, not just “brushed.”

The timed brushing flow works well. Whether it comes from the brush, the screen feedback, or the cadence of the experience, it creates a two-minute structure that keeps brushing from becoming an absent-minded speedrun. Oclean’s UI leans hard into “visible brushing,” and that idea has merit when it keeps sessions consistent. 

The brushing map is a strong concept that appears to work as intended. The X Ultra S tracks eight brushing areas via onboard sensors and highlights missed zones on the screen.  When the map matches reality, it feels like the product is doing what smart devices should do: reflecting behavior back in a way that’s easy to correct.

The battery and charging approach support real-world use. Oclean positions the brush as ideal for travel and includes a USB-C travel charging case, the kind of practical accessory that matters more than another mode buried in a menu.  Battery life is commonly cited as up to ~40 days, which aligns with the “stop thinking about charging” goal.

Oclean has done a good job on the eco front, save for the non-recyclable bags (or, if they are recyclable, they aren’t labeled as such). The box, while large, is made of eco-conscious materials. The most concrete sustainability benefit is simply that it’s rechargeable and long-lived, reducing disposable battery waste by design.

What could be improved

Cons

• Pressure sensor behavior is oversensitive and can become unusable
• Voice guidance crosses the line from “coach” to “nag,” fast
• Too many settings and gamification elements create friction instead of simplicity
• Brushing map sometimes fails to reflect the actual brushing behavior
• Time/date/weather display lacks meaningful localization for Western units or locations
• Branded brush heads may be difficult to find in some markets

The pressure sensor experience undermines confidence in the “smart” part of the toothbrush. In practice, the brush repeatedly complained about brushing pressure, even with careful, unnatural light strokes. The result wasn’t coaching—it was noise. Turning the feature off was the only path back to a usable experience, and that process took real effort, including manual digging and external support to locate the right control. When a core sensor is that jumpy, it stops being a benefit and becomes a feature that has to be managed.

The voice guidance needs a tone and sensitivity rethink, which it appears Oclean is in the process of doing, as new models don’t feature pressure feedback. Real-time prompts can be valuable, but the current execution feels too eager to interrupt. Even when the brush is technically “right,” the experience is still abrasive, especially in a setting that’s supposed to be routine and quiet. Oclean highlights AI voice guidance as a flagship capability.  In day-to-day use, it needs a more graceful default posture.

Complexity is the broader theme. The X Ultra S includes 5 modes plus additional customized modes, along with app layers, brushing reports, UI animations, and behavioral scoring.  The problem isn’t that features exist—the problem is that simplifying the experience isn’t treated as a first-class capability. A toothbrush should make routine easier, not require menu navigation for basic peace and quiet.

The brushing map is helpful, but its credibility depends on accuracy. When the brushing motion doesn’t show up in the map the way it should, the feedback loop breaks. Oclean’s tracking is built around onboard sensors and zone visualization.  When the representation diverges from reality, it creates doubt: not only about the map, but about every other metric layered on top of it. Also, it should include a fix-it mode that lets the brusher return to the highlighted areas for additional brushing. New brushing starts a new cycle; it doesn’t integrate with the most recent feedback.

The “ambient information” features—time, date, weather—feel unfinished. A screen that displays that data should support localization that matches Western units and real locations. Without customization, it becomes a demo feature: technically present, practically irrelevant. Also, not sure I need weather on my toothbrush that is sitting next to an Amazon Show.

While Oclean toothbrushes can be purchased on Amazon, the brush heads are not so available, with most of them listed as Currently unavilable at the time of this post. “Compatible” replacements are available from other vendors, but I would suggest caution, as they may not offer the same quality or cleaning capabilities as the Oclean-branded brush heads.

Oclean X Ultra S: The bottom line

The Oclean X Ultra S cleans extremely well and supports consistent brushing with a strong timing structure and a generally useful coverage map. It’s also overbuilt in ways that get in its own way: an oversensitive pressure sensor, a voice that nags too readily, and a settings-heavy interface that fights the idea of a calm routine. For anyone who wants a powerful, clean and can tolerate (or disable) the “smart” personality, it performs. For anyone who wants simplicity with premium cleaning, it tries too hard.
