Did you buy Xiaomi Mi Robot Vacuum with Chinese firmware and tired of the characters in the application? or the vacuum cleaner “speaks” in English, but you need a full-fledged Russification with voice prompts? You can reflash the robot vacuum cleaner into Russian through your computer yourself - without contacting the service center and without the risk of “bricking” the device if you follow the proven instructions.
In this article, we will discuss all the stages of firmware, from choosing the right version of the software to restoring the vacuum cleaner in the event of a failure. The emphasis is on safe methods that work for most models of Xiaomi Mi Robot Vacuum (including 1S/2/3, S50/S51, STYJ02YM and others).
⚠️ Important: Firmware through a computer requires basic skills to work with ADB If you have never updated software on Android devices, it is best to start with the official method through the Mi Home app (if it is available for your model).
1. What models Xiaomi Mi Robot Vacuum can be sewn into Russian
Not all Xiaomi robot vacuum cleaners support russification via a computer, here are the key points:
- ✅ Supported by: Mi Robot Vacuum 1/1S, Mi Robot Vacuum 2 (including LDS-Mi Robot Vacuum-Mop P, Mi Robot Vacuum-Mop 2 Lite, Viomi V2/V3 (These models are open-loader and compatible with custom firmware.
- ⚠️ Limited support: Mi Robot Vacuum 3, S50/S51, STYJ02YM — require unlocking the bootloader through Xiaomi Account (the procedure is more complicated, the risk of blocking is higher).
- ❌ New models on the Mijia platform (for example, Xiaomi Robot Vacuum-Mop 2 Pro) - they have closed firmware, Russification is possible only through official updates.
To pinpoint the model, look at the sticker on the bottom of the vacuum cleaner (e.g., STYJ02YM is Mi Robot Vacuum 2). Also check the firmware version in the Mi Home app: if it is older than 2022, the chances of successful Russification are higher.
2. What you need to firmware from a computer
Before you start, prepare:
- 💻 Computer on Windows 10/11 macOS (Linux will require additional drivers).
- 🔌 USB-cable (preferably original from Xiaomi, as cheap cables may not transmit data).
- 📱 Smartphone with Mi Home app (for backup settings).
- 🔧 Tools: Android SDK Platform-Tools (for the purposes of ADB MiRobot Tools (firmware utility) firmware with Russification (select the version for your model!).
You will also need a screwdriver (to disassemble the vacuum cleaner if you need access to UART contacts in the event of a failure) and a spare battery (firmware can take up to 30 minutes, and interrupting the process will lead to “bricking”).

3. Step-by-step instructions: how to flash Xiaomi Mi Robot Vacuum into Russian
Follow this algorithm to minimize the risks:
- Step 1. Unlock the loader (if required). For Mi Robot Vacuum 3/S50 models, you need permission from Xiaomi: Go to the unlock page. Link your Mi Account to the vacuum cleaner in the Mi Home app. Wait 72 hours (wait time may vary).
Step 2. Connect the vacuum cleaner to the computer.
Open the vacuum cleaner cover and plug in USB-contact-line 5V/GND/TX/RX (The location depends on the model. 1/2 It is enough to connect to the charging station connector.
Step 3: Set up a connection via ADB.
Open the terminal (cmd or PowerShell) and execute the commands:
adb devicesIf the vacuum cleaner is not displayed, install the drivers manually through Device Manager (select Android ADB Interface).
Step 4. Download the firmware.
Download the archive with Russified firmware (for example, mirobot_russian_vX.X.X.zip) And unpack it. At the terminal, do it:
adb push update.zip /sdcard/
adb shell reboot recoveryStep 5, start firmware.
In recovery mode, select Apply update from SD card → update.zip. Wait until the vacuum cleaner restarts automatically.
Critical detail: If the vacuum cleaner has been getting stuck on the Xiaomi logo for longer than 10 minutes, DO NOT turn it off! wait another 20 minutes - sometimes the process takes up to 30 minutes due to checksum checksums.
What if the vacuum cleaner does not turn on after the firmware?
4.Typical mistakes and how to avoid them
Even if you follow the instructions accurately, you can have problems.
| Mistake. | Reason. | Decision |
|---|---|---|
| ADB device not found | Drivers are not installed or the cable is faulty | Check the connection, install the latest version of Platform-Tools |
| The vacuum cleaner got stuck 50% when firmware is installed | Incompatible version of the firmware | Download the firmware for an exact model (for example, STYJ02YM ≠ SDJQR02RR) |
| After the firmware, there is no Russian language | Firmware without localization or resetting settings is not performed | In the Mi Home app, select the region of Russia and restart the vacuum cleaner |
| Red indicator and squeak | Damage to the loader | Sweat through UART (sweater iron and experience required) |
⚠️ Warning: If the vacuum cleaner is continuously squeaking after the firmware is running, it's a sign of hardware failure. Don't try to stitch it again, call the service. Most often, the problem is with the engine controller or the sensor. LDS.
5. How to check that the firmware was successful
After restarting the vacuum cleaner, follow the following steps:
- Check the interface language: Open the Mi Home app → select a vacuum cleaner → Settings → Language. Russian should be displayed.
- Voice prompts test: Start cleaning with a voice command (e.g., "Start cleaning"). The vacuum cleaner must respond in Russian: "I'm starting cleaning."
- Check the firmware version: In Mi Home go to Settings → The version number must match the stitched version (e.g, 3.5.8_1234 russified).
- Sensor test: Place the vacuum cleaner on a flat surface and check the work LDS-scanner (should rotate) and collision sensors (easyly press the bumper - the vacuum cleaner must leave).
💡
Before using third-party apps, disable the vacuum cleaner from Mi Home to avoid conflicts. To do this, in the Xiaomi account settings, remove the device from the list.
