Xiaomi Roborock’s robot vacuum cleaners have long been popular because of their combination of high functionality and affordable prices. However, many users face one unpleasant feature: by default, the devices speak Chinese or English, which creates discomfort when operating. Fortunately, you can install Russian voiceovers on Roborock yourself without having to disassemble the device or have special technical skills.
In this article, we will take a look at all the current ways to russify voice, from official methods through the Mi Home app to alternative solutions for older models, learn what files are needed to replace voice, how to avoid common installation errors, and what to do if the voice is lost after a firmware update, and pay special attention to the models of Roborock S7, S8, Q Revo and other popular series, taking into account their specifics.
Before you start, check the firmware version of your robot vacuum cleaner. Some methods only work on certain versions of the software, and the wrong actions can cause the device to malfunction. If you are not sure about yourself, use the official Russification channels described in the first sections.
The official ways to install Russian voice through Mi Home
The safest and most recommended method is to Russify through the Mi Home app, which is suitable for most modern Roborock models (starting with the S5 Max and later) and does not require a computer connection.
- Update the Mi Home app to the latest version via Google Play or the App Store. Older versions may not support the voice language change feature.
If your app doesn’t have a language change option, it could mean one of three:
- 🔄 The device uses outdated firmware (update it through Settings). → Update of the PO).
- 🌍 Your region in Mi Home is not set as Russia (change the application profile).
- 🚫 Robot vacuum cleaner model does not support official Russification (go to alternative methods).
Important! Once the Russian voice is installed, some system messages (e.g., error messages) may remain in English or Chinese. This is normal – full Russification is only available in unofficial firmware.
Alternative methods: manual replacement of voice files
If the official method didn't work or your Roborock model (like the S50 or S55) doesn't support language change through the Mi Home, you can manually replace voice files. This method takes longer, but gives you a complete Russification of all the clues.
- 💻 Computer with Windows or macOS.
- 🔌 USB-Type C Cable (to connect the robot to a PC).
- 📁 Archive with Russian voice files (you can download on the forums) 4PDA Xiaomi Community).
- 🛠️ Mi Home Hack or Roborock Toolbox (to access the file system).
Step-by-step:
- Download the archive with Russian voice files for your model. Please note: files for Roborock S5 will not work for S7 - check compatibility!
- Connect the robot vacuum cleaner to the computer through USB-Some models will require debugging (press the Spot Cleaning button for 5 seconds when you connect).
- Run the Roborock Toolbox program and select your model from the list. Press Connect and wait for the connection.
- In the program, go to the File Manager section and find the /miio/voice folder. back up the original files (copy them to your computer).
- Remove old files from the voice folder and upload files from the downloaded archive. Save the changes.
- Disconnect the robot from the computer and restart it. After turning it on, check the Russian voice.

Comparison of Russification Methods: Which One Should You Choose?
Not all ways to install the Russian voice are equally convenient and safe. Below is a comparison table that will help you choose the best option for your Roborock model:
| Method | Suitable models | Difficulty | Completeness of Russification | Risks. |
|---|---|---|---|---|
| Through Mi Home. | S5 Max, S6, S7, S8, Q Revo (2020–2026) | ⭐ (simple) | Partial (main commands) | Minimum |
| Manual file replacement | S5, S50, S55, E25 (older models) | ⭐⭐⭐ (middle-of-the-road) | Complete (all clues) | Firmware failure in case of error |
| Custom firmware | Any (requires unlocking) | ⭐⭐⭐⭐ (difficult) | Full + additional functions | Loss of warranty, risk of "bricking" |
| Cloud service (Valetudo) | S5–S8 (with support for alternative software) | ⭐⭐⭐⭐ (difficult) | Full + flexible settings | Requires technical knowledge |
For most users, the best solution will be the official method through Mi Home. If your model does not support changing the language through the application, and manual file replacement seems too risky - consider buying a robot vacuum cleaner with factory russification (for example, Roborock S7 MaxV for the Russian market).
💡
Manually replacing voice files gives you complete Russification, but it is only suitable for advanced users, it is better for beginners to use official methods or contact a service center.
Frequent problems and their solutions
Even after successfully installing a Russian voice, users are faced with common mistakes, and here are the most common ones and ways to fix them:
⚠️ If the robot has stopped responding to commands or makes incomprehensible sounds after Russification, return the original voice files immediately.
- 🔇 Voice lost completely Cause: file corruption when copying or version incompatibility Solution: Delete all files from the folder /miio/voice And reboot the robot, and the system will recover the standard sounds.
- 🗣️ Voice becomes silent or distorted Cause: Incorrect bitrate setting in voice files Solution: Download an alternative voice file package (look for versions marked "high quality").
- 🔄 After the firmware update, voice reset Reason: The update overwrote user files. Solution: Repeat the Russification process or roll back to the previous version of the software (if available).
- 📵 Roborock does not connect to Mi Home after changing voice Reason: File conflict with Xiaomi server Solution: Reset the robot settings to factory (hold Home" + "Power "10 seconds" and reconnect.
If none of the methods worked, check:
- 📋 Compatibility of your model with the chosen method of Russification (on the forums) 4PDA lists of supported devices).
- 🔌 Stability of Wi-Fi connection (some voice packets download over the Internet).
- 📦 Integrity of downloaded files (check checksums) MD5, if they are listed in the archive).
💡
Before any manipulation of the firmware or the robot files, record a video of the process on your phone, which will help you recover steps if something goes wrong, or show a specialist for diagnosis.
Russification through custom firmware (for advanced)
If you're willing to take risks for the sake of full control of the device, you can install custom firmware with Russian, which is suitable for the Roborock S5-S8 models and requires unlocking the bootloader.
- 🌐 Full Russification of all menus and voice prompts.
- ⚡ Additional features (e.g., Home Assistant integration without Xiaomi cloud).
- 🔧 Possibility of fine-tuning of cleaning parameters.
But there are also serious disadvantages:
- ⚠️ Loss of official warranty (Xiaomi does not support custom firmware).
- 💥 Risk of "bricking" of the device in case of error during firmware.
- 🔄 The need for manual firmware updates when new versions are released.
If you do, follow this algorithm:
- Unlock the robot bootloader through the Mi Unlock Tool (you need a Xiaomi account with a linked phone number).
- Download custom firmware with support for Russian (popular options: Valetudo or DustBuilder).
- Connect the robot to your computer in fastboot mode (press Spot Cleaning + Dock when you connect USB).
- Switch the device through the command: fastboot flash system custom_rom.img (substitute custom_rom.img in the name of your firmware file).
- Wait for the process to be completed and restart the robot.
⚠️ Attention! Castom firmware may contain vulnerabilities or unstable features, and do not install them on robots used for commercial purposes (e.g., for cleaning offices).

How to get your original voice back if something goes wrong
If the robot vacuum cleaner starts to work incorrectly after Russification (it does not respond to commands, constantly reboots or makes extraneous sounds), you need to return the standard settings.
- Reset to factory settings: Hold the Home buttons and Power on the robot body for 10 seconds until you hear the beep. After reset, reconnect the device to Mi Home again.
- Recovery of original voice files: If you have saved a backup of the /miio/voice folder, return the files back using the Roborock Toolbox. If there is no copy, download the standard files for your model on the forums.
- Flash through Mi Home: In the Mi Home app, go to Device Settings → Software Update and select the Factory Firmware Restore option (if available).
- Contact the service center: If the robot does not turn on or respond to the reset, contact the authorized Xiaomi service. Please report that the problem occurred after the software update (do not mention custom firmware, so as not to lose the warranty).
In most cases, hard reset helps, and if the robot is not showing any signs of life (the indicator does not burn, does not respond to charging), the controller may have failed, in which case repairs will be required at the service center.
