Many Chinese consumers are faced with a nasty surprise when buying smart appliances: the device or mobile app interface is entirely in Chinese.This makes the initial customization of the robot vacuum cleaner a real quest that requires savvy and patience. Fortunately, Xiaomi engineers have envisioned several ways to solve this problem, although they are not always obvious to the beginner.
Changing the language depends not only on the model of your gadget, but also on the firmware version, as well as on the selected region in the application. Often the problem lies not in the device itself, but in the wrong settings of the Mi Account. In this article, we will discuss in detail all possible methods of localizing the interface, from simple switches to complex manipulations with the region.
Before you start active, you need to make sure that your device is fully charged and is in the zone of confident reception of the Wi-Fi network. An unstable connection can interrupt the process of changing the language pack, which will lead to a freeze, and it is also recommended to download the latest version of the Mi Home application from the official store in advance.
Definition of the model and firmware version
The first step should always be to identify your device. Different lines of robot vacuum cleaners, such as Roborock, Viomi or Dreame, can have excellent localization algorithms. Some models support multilingualism out of the box, while others, especially the Chinese version (CN Version), require a change of region to display English or Russian.
To find out the exact model, flip the device over and look for a sticker on the bottom panel. You're interested in a combination of letters and numbers, like SDJ02NM or Vacuum-Mop-2-Pro. This information is critical when looking for specific instructions or firmware on forums. Without an accurate knowledge of the model, it's easy to get confused in the menu, because the location of items varies across generations.
The firmware version also plays a key role: older versions of software may not contain the necessary language packages, even if the region is selected correctly; you can check the current version in the application by entering the device settings, even if the interface is not yet clear, usually at the bottom of the settings list and is indicated by numbers.
⚠️ Warning: Attempting to install firmware from another device model may cause permanent damage to the electronics ("brick"). Make sure the files match your serial number.
Modern localization algorithms are often tied to the user's location. If you're in Russia, but the app is China, the system can force the Chinese interface to be displayed without the smartphone's language settings, so understanding your model architecture is the foundation of a successful setup.
💡
Accurate knowledge of the model and version of the software determines the choice of the method of changing the language: from a simple switch to changing the region of the account.
Setting up the language through the Mi Home app
The main tool for managing smart technology is the Mi Home app, which is where you first set up and change system settings, and if your robot vacuum cleaner supports language change software, you should look for this option in the application interface, not on the device body.
The process of changing settings is as follows:
- 📱 Open the Mi Home app and make sure your account is logged in.
- 🏠 Click on the icon of your robot vacuum cleaner on the home screen to enter control.
- ⚙️ Find the settings button (usually three dots in the upper right corner or gear).
- 🌐 In the menu that opens, look for “Voice” or “Language” (often indicated by a speaker or globe icon).
In some cases, the application interface language and the robot's voice are set up separately. You can leave the menu in English, but choose Russian voice for commands. In Settings → Voice Package, you need to select the desired language and press the download button. The process can take several minutes depending on the speed of the Internet.
If there is no explicit language switch on the menu, try changing the language of the smartphone itself. Many Xiaomi apps automatically adapt to the system language of the Android or iOS operating system. Go to the phone's settings, find the "Language and Input" section, and install Russian. After restarting the application, the interface can change automatically.
💡
If the language doesn’t change after changing your phone’s settings, try to close the app completely (unload it from memory) and start it again.
It is worth noting that global versions of devices intended for sale in Europe and the CIS usually have built-in Russian. Problems most often arise with devices imported through parallel imports from China, in which case the interface can be rigidly tied to English or Chinese without the possibility of changing through the standard menu.
The method of changing the region to unlock the language
The most effective way to “russify” Chinese versions of robot vacuum cleaners is to change the region in the Mi Home app. Xiaomi servers distribute content and language packages depending on the geographic location of the account. By switching the region to Russia, Ukraine, Belarus or Singapore, you can access the English or Russian interface.
To perform this procedure, perform the following actions:
- 🌍 Go to the user profile (the "Profile" or "Me" tab in the lower right corner).
- ⚙️ Select the "Settings" option (Settings).
- 📍 Click on the line "Region).
- ✅ Select a country from the CIS or Singapore (often the most complete localization).
Once you change region, the app will reboot and the interface should be clear, but there's an important caveat: devices added in the Chinese region may not appear on the list if you switch to Russia, in which case the device will have to be removed from the application and re-associated from the new region, which requires resetting the Wi-Fi module on the vacuum cleaner itself.
Changes in region also affect the availability of certain features, such as maps of premises or cleaning history can be stored on servers of the selected country; with frequent changes in regions, history can be lost or unavailable, so it is recommended to choose one main region and stick to it.
Sometimes changing the region doesn't give you an instant result, so try clearing the app's cache. Go to your smartphone settings, find the Apps section, select Mi Home, and click Clear Cache. Don't confuse Clear Data with Clear Data, because that will require you to log in again.
Resetting Wi-Fi and re-binding the device
If a region change doesn’t help or the device refuses to work properly with the new server, a complete reset of network settings and re-binding may be required, a radical but often the only way to get the Chinese version of the vacuum cleaner to “speak” in the desired language.
The process of resetting the Wi-Fi module varies depending on the model, but most often it requires the simultaneous pressing of two buttons on the case. Usually this is the on button and the return button to the base (or the spot clean button). Hold them for 5-10 seconds until the characteristic beep or voice message in Chinese / English.
Once reset, the Wi-Fi indicator should start flashing, signaling the pairing mode. Now you can re-add the device to the application, making sure that the Mi Home settings have already chosen the right region. When you first connect, the system may suggest updating the firmware — agree, as new versions often fix localization errors.
The robot will need to rescan the apartment and build a map, and make sure that the room is light and there are no obstacles to the process to be as accurate as possible.
☑️ Checklist for device re-binding
In rare cases, the device may stick to the old server, so you can completely delete the account from the application and register a new one with the correct region from the beginning, which takes longer, but guarantees a clean setup without data conflicts.
Voice control and language packs
Special attention should be paid to the voice control settings. Even if the text interface is translated, the robot can continue to give commands in Chinese. To change the voice, you need to download the corresponding language pack. In modern models, this is done through the Settings menu → Voice → Voice Package.
The list of available votes depends on the model:
- 🗣️ Global versions: usually have built-in English, Russian, German.
- 🇨🇳 Chinese versions: often limited to Mandarin, sometimes English.
- 🤖 Third-party packages: for some models, enthusiasts create custom voices.
If there is no Russian on the list but there is English, it is recommended to choose it.English is the universal standard for control commands, and most users quickly get used to the commands "Start", "Pause", "Charge".Using English voice also provides better compatibility with voice assistants.
⚠️ Warning: Do not interrupt the download of the voice packet. If the process is interrupted in the middle, the voice module may stop working until the next full flashing.
For advanced users, it is possible to install custom voice packets through ADB debugging, but this requires technical skills and carries risks. It is safer for the average user to limit the regular capabilities of the application.
Comparison of localization methods
To make it easier for you to choose the right way, we have organized the information in a table, each method has its advantages and disadvantages, which depend on the specific situation and model of your device.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Change of language in the annex | Low. | Medium | Minimum |
| Changing the region of the account | Medium | Tall. | Loss of card history |
| Resetting and re-binding | Tall. | Maximum | Difficulty setting up Wi-Fi |
| Changing the language of the smartphone | Low. | Low. | No. |
As you can see from the table, the most universal method is to change the region, which solves the problem 90 percent of the time, but if you're afraid of losing the accumulated map data, start by trying to change the language in the settings of the app or smartphone.
Remember, the software is constantly updated. What worked a year ago may have a different algorithm today. Always check for firmware updates, as the manufacturer may add support for new languages to new versions of the software.
