How to Sweep Xiaomi Robot Vacuum into Russian via Phone: Complete Guide 2026

Xiaomi Mi Robot Vacuum (including models) 1S, 2 Pro, STYJ02YM And others, which are often supplied with Chinese firmware, which creates problems with voice localization, application and functionality. Russian firmware via the phone solves these problems, but requires care: wrong actions can turn the device into a brick. In this article, all the working methods of 2026, including official and alternative methods, taking into account the features of different models and versions of the software.

The main challenge is that there is no one-size-fits-all solution, for example, for Mi Robot Vacuum-Mop 2 Lite, one method is suitable, and for Mi Robot Vacuum-Mop P, another method is suitable.

1. Official update via the Mi Home app (the safest way, but it doesn’t work for all regions).
2. Firmware through ADB using modified files (requires unlocking the bootloader).
3. Install custom firmware via Valetudo or Dustcloud (for advanced users).

Before you start, make sure your model supports Russification – some devices (e.g. Mi Robot Vacuum) E10) have hardware limitations.

1. Firmware Preparation: What to Do Before Starting

The first step is to determine the current firmware version and device model, and this information is critical: an inappropriate firmware file can cause a system to crash.

1. Turn over the vacuum cleaner and find a sticker with the serial number (for example, STYJ02YM).
2. In the Mi Home app, go to the Device Profile → Settings → About the device.
3. Compare the version with the compatibility table below.

Also prepare:

• 📱 Smartphone on Android 8.0+ (iPhone methods are limited) with enabled debugging USB.
• 🔌 USB-Type-C Cable (original, undamaged).
• 💾 Backup of vacuum cleaner settings (export cleaning cards to Mi Home).
• 🔋 Charge vacuum cleaner at least 50% (when discharged during firmware failure is possible).

⚠️ Note: If your vacuum cleaner is tied to a Chinese Mi Account, reset through Settings first → Reset to the factory, otherwise, after the firmware, the device may lock.

2. Method 1: Officially Update via Mi Home (Securest)

This method works for models that support multi-regional firmware (e.g. Mi Robot Vacuum). 1S with software version 3.5.8:

1. Remove the vacuum cleaner from the Mi Home app (if already added).
2. Change your account region to Russia or Europe in your profile settings.
3. Add the device again by selecting the server Europe (Frankfurt).
4. After connecting, check for updates in Settings → Update of the PO.

If the update does not appear:

• 🔄 Restart the vacuum cleaner (hold the power button for 10 seconds).
• 📶 Connect to another Wi-Fi network (for example, from a mobile phone).
• ⏳ Wait 24 hours – sometimes updates are delayed.

⚠️ Warning: After the update, all stored cleaning cards will be reset. To restore them, export the data through Settings before the firmware. → Maps. → Exports (not available on all models).

Critical detail: if after updating the application there are Chinese characters, reinstall Mi Home and log in again - this often solves the problem with the localization cache.

3. Method 2: Firmware through ADB (for advanced users)

The method is suitable for models that do not support official Russification (for example, Mi Robot Vacuum-Mop 2 Pro).

• Computer with Windows/Linux root-access smartphone.
• Utility. ADB (Download Platform Tools).
• Modified firmware (see forums) 4PDA Xiaomi Community on the model of the device).

Step-by-step:

1. Enable the developer mode on the vacuum cleaner: Press and hold the Home buttons" + "Power 5 seconds until you hear a voice message.
2. Connect the vacuum cleaner to your computer/phone through USB and execute the command: Adb devices The device should appear in the list.
3. Download the firmware in the vacuum cleaner memory: adb push firmware.ru.zip /sdcard/
4. Install firmware: adb shell am start -a android.intent.action.VIEW -d file:///sdcard/firmware.ru.zip

The process will take 5-10 minutes. After restarting, the vacuum cleaner must load with the Russian interface.

adb backup -f backup.ab -apk -shared

This will help restore the device in case of failure.-->

4. Method 3: Custom firmware (Valetudo/Dustcloud)

For models without official support of the Russian language (for example, for the first time, STYJ02YM) They use alternative firmware like Valetudo or Dustcloud:

• 🌍 Complete Russification of the interface and voice prompts.
• 🔓 Unlock additional features (e.g., zoning without internet).
• 🛡️ No dependence on Xiaomi servers.

Cons:

• ⚠️ Requires unlocking the bootloader (risk of loss of warranty).
• 🔧 You need skills to work with Linux or Termux on Android.
• 🔄 Updates will have to be installed manually.

Instructions for Valetudo:

1. Install Termux on Android and execute: pkg install git python wget git clone https://github.com/Hypfer/Valetudo.git cd Valetudo./install.sh
2. Connect the vacuum cleaner to the same Wi-Fi network as the phone.
3. Open the browser. http://[IP-vacuum-dress]:8080 And follow the customization wizard.

Important: Once Valetudo is installed, the vacuum cleaner will no longer work with the Mi Home, and it will only be managed via the web interface or the Valetudo App.
