Owners of Xiaomi equipment often face a situation where, after buying or resetting the settings, the smart vacuum cleaner begins to speak Chinese, ignoring the usual voice commands in Russian or English. This is because global versions of devices, when first activated or flashed, can inherit regional settings of the warehouse from which the goods were delivered. The user needs to perform a series of specific actions to make the interface and voice assistant speak in an understandable language, since the standard switch in the menu of the device itself often simply does not exist.
The process of changing the language package depends on the model of your Xiaomi Vacuum and the version of the software installed on board. Old models require a full reset and re-assignment through the application, while new flagships allow you to change the settings through the cloud server after choosing the right region. It is important to understand that the audio files of voice support are not stored in the robot memory, but are downloaded from the application servers at the time of synchronization.
In this guide, we will detail the algorithms for various series of robot vacuum cleaners, including the Mi Robot series, Roborock and Dreame. You will learn how to properly configure the region in the Mi Home application to activate the desired language, and what to do if the device is stuck in Chinese forever. It is critical to reset the Wi-Fi module before setting up, otherwise the application may not offer a change of language when reconnecting.
Features of localization in the Xiaomi ecosystem
Xiaomi’s smart home ecosystem is built on the principle of regional server segmentation, which means that the language of the device is determined not only by the firmware, but also by which server it is connected to at the time of registration. If you bought a device designed for the domestic market of China, or accidentally chose the “China” region on the first launch, the robot will use the corresponding language package. Changing the language often requires not just switching the switch toggle in the settings, but actually re-registrating the device to the server of another country.
Modern models like the Xiaomi Robot Vacuum X10+ or Dreame L10s Ultra have a more flexible localization system that can automatically detect the language you have installed on your smartphone and tighten the appropriate audio files, provided that the application selects the right region. However, if the device was previously associated with another account or region, it can block the change of parameters until the network settings are completely reset.
There is also the concept of Global Version and CN Version, and global versions usually have built-in support for multiple languages and are easy to switch; Chinese versions require more complex manipulation because their underlying firmware is tailored to local services; in some cases, full-fledged Russianization of Chinese versions requires a device to be reflashed to a global version of the software, which carries the risk of loss of warranty.
⚠️ Attention: If you change region in the Mi Home app, the list of your devices may temporarily disappear.Don't panic, this is normal system behavior, as the devices are tied to specific servers.
Understanding these differences will help you choose the right way to solve the problem. Don’t try to change the language through hidden menus of engineering diagnostics, unless you have special knowledge, as this can lead to software failure and failure of the device.
Preparation for the change of language: reset and diagnosis
Before you start actively changing the language, you need to get the device ready for the new configuration. Standard procedure requires the robot vacuum cleaner to be on standby and not perform the current cleaning. The first step is always to reset the Wi-Fi connection, which breaks the connection with previous server settings.
For most Xiaomi and Roborock models, the reset procedure looks the same. You need to simultaneously press two buttons on the device body: the power button and the return button to the base (or the spot clean button). Hold them for 5-10 seconds until you hear a voice message or a characteristic beep. After that, the Wi-Fi indicator should start flashing, which signals the transition to pairing mode.
☑️ Checklist of device preparation
It is important to make sure your smartphone is connected to a 2.4GHz Wi-Fi network. Xiaomi vacuum cleaners do not generally support 5GHz networks, and trying to set up on such a network will result in a connection error that you will not be able to complete the language change process. Also check that geolocation and Bluetooth are enabled on the phone, as modern Mi Mesh and BLE protocols use them to quickly detect the device.
If the device was previously linked to another Xiaomi account, you need to untie it. Go to the device settings in the app, scroll down and select Delete Device. Only then you can start the process again. Ignoring this step will lead to the error "Device is already occupied", and you will not change the language.
Instructions for changing the language through the Mi Home app
The main method of changing the language is to set it up correctly through the mobile app. If you have already added a device but the language is still Chinese, you better delete it and add it again, following a strict algorithm. Open the Mi Home app and make sure that the region corresponding to the desired language is selected in the upper left corner (for example, "Russia" for Russian or "Singapore" / "Germany" for English).
Click on the plus in the upper right corner to add a new device. The app will start scanning the space. When your vacuum icon appears on the screen, click on it. During the connection, the app will prompt you to select a name and room. This is where the language pack is requested from the server. If the application region and the server region match, the robot will download the desired voiceover.
You may need to update your firmware during the setup process. Don't miss this step. Often new language packs are introduced with software updates. Wait until you finish downloading and installing without turning the vacuum cleaner off the network. Once you update, the device automatically restarts and applies new language settings.
After a successful addition, check the voice commands. The robot should greet you in the chosen language. If that doesn't happen, check the settings of the application itself. In the Profile -> Settings -> General section, you can sometimes find a forced language setup that overrides the phone's system settings.
Setting up the region for different models of vacuum cleaners
Different product lines use different server clusters, so choosing a region in the Mi Home app is critical. A mistake in choosing a region can lead to the device being unstable or not supporting management from anywhere in the world.
Below is a table of correspondence regions for popular models:
| Model of the device | Recommended region | Language default | Features |
|---|---|---|---|
| Xiaomi Vacuum Mop 2 Pro | Russia / Europe | Russian/English | Support for Yandex.Alice |
| Roborock S5 Max | Germany/Singapore | English | Need a separate Roborock account |
| Dreame D9 | Russia | Russian | Full integration with Mi Home |
| Xiaomi Vacuum 1S | China (sometimes) | Chinese/English | Requires a change of region for Russification |
Roborock devices often require a separate account to be created in the Roborock app, which then links to Mi Home, in which case the language changes in the settings of the Roborock app itself, and the region is selected when you register your account, and you can’t change the region of the already created Roborock account, you have to register a new one.
Devices made specifically for the Chinese market (often with characters on the box and in the instructions) may require the selection of the "China" region in the Mi Home app. In this case, it is almost impossible to get Russian in regular ways. The only option is to use third-party firmware methods or to accept the English / Chinese interface.
⚠️ Note: When choosing a region called China, the speed of the application may be lower due to remote servers, and some features, such as integration with voice assistants, may not be available.
Problem Solving: When the language doesn’t change
Even if all instructions are followed, there can be situations where the robot vacuum cleaner persists in speaking a foreign language, which is often the case with models that were manufactured for the domestic market of China and resold through third countries, in which case a standard change of region in the application may not help, since the hardware identification of the device indicates a Chinese region.
One solution is to use the "Region Change" function inside the Mi Home app itself, but with the cache cleared completely. Go to the profile settings, select the region change, confirm the action. The app will reboot. After that, try adding the device as new. If this doesn’t work, try connecting your phone to the mobile internet (3G/4G), Turn off your Wi-Fi, and repeat the addition process. IP-Country address helps the server to determine the correct language packet.
There's also a method of changing language through voice commands, but it only works on models with a display or advanced voice system. Try saying "Switch language" or "Change language to English." However, the likelihood of success here is low if the device doesn't initially support multilingualism at the base firmware level.
If nothing works, the flashing option remains, a complex process that requires PC connectivity, special cables (UARTs) and firmware. For ordinary users, this method is not recommended because of the high risk of turning the device into a brick. It is easier to adopt English as the main language, since it is the universal standard for all Xiaomi equipment.
