Xiaomi launched the Mijia Sonic Sweep Electric Toothbrush in China on September 25, 2024, with a crowdfunding price of 119 yuan and a reported retail price of 199 yuan. Its headline feature is an approximately 180-day battery claim in Gentle mode, alongside USB-C charging and an onboard reminder for areas that may have been missed while brushing.
This was a China-focused Xiaomi Youpin launch—not confirmation of a US or worldwide release. The model can also appear under regional naming such as Xiaomi Oscillation Electric Toothbrush, which makes it important to distinguish it from newer Mijia Pro toothbrushes now listed on Xiaomi’s global websites.

Price and availability
The Mijia Sonic Sweep Electric Toothbrush was introduced through Xiaomi Youpin crowdfunding in China at 119 yuan. Its reported standard retail price was 199 yuan. The dollar equivalents reported at launch—roughly $17 and $28—were approximate conversions at the time, not current US prices.
Recommended Free Tools
Neither figure establishes official availability in the United States or any other particular market. Overseas buyers should treat third-party imports separately from official regional sales and check shipping, taxes, seller authorization, warranty coverage, firmware or language limitations, and access to genuine replacement heads. The original launch report is available from Gizmochina.

What the 180-day battery claim means
Xiaomi’s global product information gives the approximate 180-day figure under specific conditions: a full charge, Gentle mode, two minutes of brushing per session, and two sessions per day. That equals four minutes of motor use daily, or roughly 12 hours of total brushing time over 180 days. The 12-hour calculation is an inference from Xiaomi’s stated assumptions, not an independent battery test.
The same official information lists approximately 100 days in Standard mode. Deep Sweep mode, longer sessions, more frequent use, battery aging, temperature, and other conditions can reduce the actual interval between charges. The headline number should therefore be read as a best-case operating estimate rather than a universal runtime guarantee.
Charging uses USB-C, which is convenient for travel and avoids a proprietary charging cradle. Xiaomi nevertheless warns users to ensure the charging port is dry before connecting a cable.

Rank #2
- Designed as replacement heads, fitting MES609 and MES6010 sonic electric toothbrushes.
- Features bristles, suitable for use in daily oral care routines.
- Comes in sealed packaging, helping keep the heads protected before first use.
- Easy to install and replace, requiring no extra tools for convenient handling.
- Works well with compatible electric toothbrushes, supporting consistent performance during brushing.
What are the three cleaning modes?
- Gentle: intended by Xiaomi for beginners or people with sensitive gums.
- Standard: the everyday cleaning setting.
- Deep Sweep: a more intensive setting described as helping address gaps and harder-to-reach areas.
These descriptions explain Xiaomi’s intended use; they do not prove that one mode clinically cleans better for every person. Anyone with persistent bleeding, pain, significant sensitivity, braces, implants, gum disease, or another dental concern should follow advice from a qualified dental professional rather than choosing a mode solely from marketing descriptions.
How the “smart reminders” work
The original toothbrush does not need to be described as a smartphone-based oral-health tracker. Its reminder system is an on-device, four-zone indicator that uses the handle’s orientation and brushing duration to estimate whether parts of the mouth may have received insufficient attention.
According to Xiaomi’s description, a white indicator represents areas the system considers adequately cleaned, while a pulsing orange light flags areas that may need more brushing. This is guidance based on the device’s algorithm—not a clinical measurement of plaque, gum health, or brushing quality.
Do not assume that the 2024 Sonic Sweep supports Xiaomi Home, generates a complete tooth-by-tooth map, or offers pressure monitoring. Those features are associated with newer Pro models, not established specifications for the original launch product.
Brush head and everyday hardware
Launch and official materials describe a brush head with copper-free bristle insertion and a shock-absorbing or rubber-coated construction designed to reduce uncomfortable tooth impact. Xiaomi qualifies the experience because tooth structure and brushing technique vary; “designed to reduce impact” should not be interpreted as a guarantee that collisions or discomfort are impossible.
The bristles include a color-fade replacement reminder, and Xiaomi’s materials describe replacing the head approximately every three months. That recurring supply is a practical consideration for imported units. Before buying, verify that genuine heads are sold in your country and that the seller confirms compatibility with this exact model. Compatibility should not be assumed across Xiaomi, Mijia, or T-series toothbrush heads.
Other practical features include a three-second gradual start, intended to reduce toothpaste splatter, and mode memory. Color availability varies by market and edition: the Chinese launch coverage mentioned white, pink, and blue, while one Xiaomi global page lists white and blue.

The toothbrush is listed with an IPX8 water-resistance rating. That is a manufacturer-listed protection rating, not permission to charge the brush while wet or submerge the USB-C port. Dry the charging connection fully before charging and follow the instructions supplied with the regional version.

Do not confuse it with Xiaomi’s newer Pro toothbrushes
Similar battery headlines can refer to different products. Xiaomi’s current global pages list newer toothbrushes, including the Mijia Smart Servo-oscillation Electric Toothbrush Pro. That is a later model generation, not the September 2024 Sonic Sweep launch.
| Feature | 2024 Mijia Sonic Sweep | Newer Mijia Smart Servo-oscillation Pro |
|---|---|---|
| Battery claim | Approximately 180 days in Gentle mode; 100 days in Standard mode | Approximately 180 days in Gentle mode; 90 days in Standard mode |
| Feedback | Four-zone missed-area indicator | Color display and more detailed tracking |
| App support | Do not assume Xiaomi Home integration | Xiaomi Home integration is listed |
| Advanced sensing | Not established for the original launch model | Pressure sensing and six-axis tracking are listed |
| Launch context | China crowdfunding launch in September 2024 | Appeared on Xiaomi’s global website; pricing and country-by-country availability were not established |
See the official pages for the Xiaomi Oscillation Electric Toothbrush and Mijia Smart Servo-oscillation Electric Toothbrush Pro. Xiaomi also lists a regional Xiaomi Oscillation Electric Toothbrush Pro in the UAE, with its own display, tracking, modes, and battery specifications.
What to check before importing one
- Confirm the exact model number and regional product name.
- Check whether the seller is authorized and whether the warranty is valid in your country.
- Verify what is included: USB-C cable, spare heads, charging accessories, and documentation.
- Price genuine replacement heads and confirm they are actually available.
- Check language, firmware, app, and regional-service limitations if considering a connected Pro model.
- Keep the charging port dry, even if the handle carries an IPX8 rating.
A low Chinese launch price can lose its advantage once international shipping, tax, seller markup, warranty risk, and replacement-head costs are included. For readers who want app reports, pressure alerts, and a display, the newer Pro is the relevant product to investigate. For readers who want a simple travel brush, the Sonic Sweep’s USB-C charging and long claimed endurance are more relevant than connected features.
Bottom line
The Mijia Sonic Sweep’s strongest selling points are its low China launch price, USB-C charging, simple missed-area guidance, and claimed long endurance—180 days only under Xiaomi’s Gentle-mode, two-minutes-twice-daily conditions. It should not be presented as clinically superior, app-connected, or officially available in the US without country-specific confirmation. Check replacement-head supply and warranty support before treating an imported unit as a bargain.
