Xiaomi's new AI toothbrush uses a gyroscope to catch where you're brushing wrong
Xiaomi has launched a toothbrush that borrows motion-sensing tech from gaming controllers: the Mijia Multi-directional Sweeping Electric Toothbrush Pro, listed on Xiaomi Youpin crowdfunding in China. It combines a dual-axis vibration motor with a six-axis gyroscope and accelerometer to track the angle and position of the brush head in real time. Whether that translates into meaningfully cleaner teeth is another question — but the hardware spec punches above the typical mid-range price.
The hardware
The standout feature is the multi-directional motor setup. Instead of a single back-and-forth oscillation plane, the brush head adapts its movement to follow the curve of your teeth. The built-in gyroscope identifies which surface it's on and adjusts the cleaning pattern accordingly — a step up from the fixed modes on most sonics in this bracket.
More practically useful is the automatic pressure reduction. Press too hard and the brush cuts its power, flashes a red warning light, and vibrates differently to let you know. Dentists have flagged overzealous brushing as a leading cause of gum recession, so a hardware-enforced limit is a genuine improvement over a simple indicator light.
Three heads, one app
The Pro ships with — and sells separately — three brush head types: a standard daily head, a sensitive/delicate option, and an enamel-whitening head. The rubber-coated body is designed to stay grippy with wet hands, and it comes in three colors.
Three interchangeable brush heads cover daily, sensitive, and whitening use cases.
Syncing to the Mi Home app unlocks personalized cleaning modes, bristle wear tracking, and brushing reports. The app angle is now standard for connected toothbrushes, and Xiaomi's version appears comparable to what Oral-B and Philips offer on their premium models — which typically cost considerably more.
Availability
This is where things get uncertain. The Youpin listing is a China crowdfunding page; there is no confirmed UK or US retail date. Xiaomi's current toothbrush lineup in English-speaking markets is anchored by the T500 and T700 (around £40–60 on Amazon UK), and no Pro variant has appeared on official Xiaomi stores or major retailers. If the Pro does reach Western markets, expect pricing above the T700 given the added sensor hardware. For now, GagaGadget's overview is the clearest English-language summary of the specs.
