Smart tech owners often find themselves finding their voices sounding unusual or even annoying after buying a device, and Xiaomi’s robot vacuum cleaners often come with a Chinese or English voice package by default, which can create discomfort in everyday use in Russian-speaking environments. Fortunately, the Mijia ecosystem and Mi Home app provide users with extensive customization options, including changing their language and installing new voice assistants.
The process of changing the voice does not require deep technical knowledge or manual flashing of the device, but it requires attention to the details of the setting of the region. Many users mistakenly believe that the language changes only in the application interface, but in fact the audio files are stored in the memory of the robot itself and depend on the server chosen. The correct setting will allow your gadget to speak in your native language, reporting the status of cleaning, errors or the need to empty the container.
In this article, we will discuss all the stages of changing voice support, look at the features of working with various models such as the Roborock S50, Roborock S5 Max or Xiaomi Vacuum Mop Essential. You will learn how to avoid locking the device when changing regions and what alternative methods are available for advanced users who want to install unique voice packs.
Features of voice control in the Xiaomi ecosystem
Voice support in Xiaomi and Roborock devices is implemented through a system of pre-recorded audio files that are activated depending on the state of the robot vacuum cleaner. Unlike smart speakers that use cloud speech synthesis, vacuum cleaners often rely on local files, which ensures the operation of voice notifications even in the absence of a stable Internet connection, which is why choosing the right region in the Mi Home application is a critical step.
When you change region in the application, the servers of the company synchronize, and the corresponding language pack is loaded onto the device. If you choose the region "China", the robot will speak Chinese, even if the application interface is in Russian. To get Russian voiceover, you need the server part to support this language for a particular device model.
⚠️ Warning: If you change region in the Mi Home app, your device list may temporarily disappear from the main menu.Don't panic or delete devices - they will return after switching to the correct server and restarting the application.
Flagship models such as the Roborock S7 or Xiaomi Robot Vacuum X10+ typically have a full range of languages, including Russian, English, German and Chinese. Budget versions such as the Xiaomi Vacuum-Mop 2 Lite, can have a limited set of voice packs, depending on the firmware version.
Preparation for installation of voice packets
Before you start changing your voice settings, make sure your hardware and software are ready for the procedure.The first step is to check the version of the Mi Home app (or Xiaomi Home).Older versions may not have access to new servers or media management features, making it impossible to change voice.
It is also important to ensure that the robot vacuum cleaner is connected to the Wi-Fi network. The process of uploading voice data requires file transfer, and a communication interruption at this point can cause the device to remain without a voice or go into silent mode. Make sure that the robot is on base and charged at least 20%.
☑️ Ready to change voice
In some cases, linking the device to the “China” region blocks the ability to change voice into other languages without detachment and re-binding. If you bought the device through “gray” imports, it may be initially tied to a Chinese server, which will require additional actions to localize.
💡
Before you start manipulating the regions, take a screenshot of the current settings of the device, which will help you quickly restore the settings if something goes wrong.
Main method: change the region in the Mi Home application
The easiest and safest way to install voices on a Xiaomi robot vacuum cleaner is to change the region in the application settings. This method does not require root rights or the use of third-party software. The algorithm of actions is simple: open the application, go to the profile, select a region and specify the country corresponding to the desired language (for example, Russia for Russian or Germany for German).
Once you change region, the app will need to reboot, and when you log in again, you'll see that the device may appear offline or disappear, and then you'll need to add the device back, scanning it. QR-If you're using the code or you're selecting it from the list, but in a new region, and if you're connected successfully, the robot vacuum cleaner automatically downloads the language resources that you need.
If you don't automatically download, check the audio settings in the device menu. In some models, the path to settings is Settings → Voice → Language Selection. Here you can see the packages available and activate the desired one. If the desired language is not on the list, then it is not provided for the selected region by the manufacturer.
| Region in annex | Main language | Availability of functions | Risks. |
|---|---|---|---|
| Russia | Russian | Full (for official models) | Low. |
| China | Chinese | Maximum (all models) | Difficulty of localization |
| Singapore | English | Tall. | Lack of Russian language |
| Germany | German | Tall. | Lack of Russian language |
⚠️ Warning: Changing the region to China often opens up full functionality, but it can deprive the device of Russian. Be careful when choosing a server if you want to localize the interface and voice.
💡
Region change is a key trigger that causes the server to send the corresponding language packet to the device, and without changing the region in the profile, the change of voice is often impossible.
Installation of voice packets via Mi Home (detailed instructions)
For those who want to more nuancedly manage settings, there is an advanced method through the device management menu. Once you've made sure the application region matches the desired language, go to your robot vacuum cleaner card. Click on the three dots in the top right corner of the screen to enter the settings menu.
In the list that opens, look for "Device Settings" or "General Settings." Inside this section, look for "Voice" or "Voice." This can show the current language. Clicking on this item initiates update checks. If your model has another voice, the system will prompt you to download it.
Way to Menu: Device Card →... (three dots) → Settings → Voice → Language Selection → DownloadDuring the booting process, the progress bar will be displayed on the smartphone screen, during which time the robot can emit sounds or light signals, it is strongly recommended not to interrupt the process, as this can damage the audio module file system. Once the boot is completed, the device will automatically restart the audio service.
Sometimes users are faced with a situation where there is only one language on the list, which means that the current version of the firmware is rigidly tied to one region, in which case you may need to update the firmware of the vacuum cleaner to an international version, if one is available for your model.

Compatibility issues and choosing the right model
Not all Xiaomi models are equally friendly to changing languages. Devices released exclusively for the domestic market of China (Global Version vs. China Version) may have a blocked voice packet loader, in which case a standard change of region in the Mi Home application may not work.
The Roborock series (S5, S6, S7) is a sub-brand of Xiaomi, which often has its own Roborock app. In this app, voice change can be implemented more flexibly, without having to change the region of the main Mi Home account.
- 🤖 Roborock S50/S55: Supports language change through the Roborock app, but requires a country-specific server link.
- 🧹 Xiaomi Vacuum Mop Essential: Budget model, often with only one hard-sewn language, party-dependent.
- 🚀 Xiaomi Robot Vacuum X10+: Flagship with multilingual support and the ability to upload voices through the cloud.
It's important to understand the difference between localization and voice packet. The application interface can be in Russian while the robot speaks Chinese. This is normal for gray devices. Full localization is achieved only by matching the account region, device region and firmware version.
⚠️ Note: Buying a device in the Chinese market (CN Version, you risk getting a gadget that cannot be fully translated into Russian without complex firmware manipulations, which can lead to a loss of warranty.
Alternative methods and advanced settings
For enthusiasts who don’t like standard voices, there are methods for installing custom audio packages, a process known as “voice modification” that requires access to the robot’s file system, often through ADB protocol or special hacking utilities.
The method is to replace system audio files (.ogg or.mp3) in the /data/roborock/sounds folder (the path may differ) with user-recorded files. There are ready-made voice sets, such as a character's voice from a game or famous quotes.
Example of a command to obtain rights (requires root):
adb shell
su
cd /data/roborock/sounds
mv current_voice.ogg backup.ogg
cp custom_voice.ogg current_voice.oggUsing third-party software like Valetudo or VacuumZ also allows voice notifications to be managed more flexibly, and these open platforms replace Xiaomi’s standard cloud with a local one, giving full control of the device, including speech synthesis via Google TTS or Amazon Polly.
💡
Custom firmware or file replacement gives you full control of your voice, but it voids the warranty and requires technical skills. For most users, a standard region change is enough.
