How to change the language of the robot vacuum cleaner Xiaomi Mijia: the complete guide

Modern smart cleaning devices, such as the Xiaomi Mijia series of robot vacuum cleaners, often come with Chinese or English pre-installed interface languages, due to differences in regional versions of firmware that manufacturers produce for different markets. A user who bought the device in an international store or brought it from a trip may face the need to localize voice packets and text menus.

The process of changing the language depends on the specific device model, whether it is Roborock, Dreame or classic Xiaomi Vacuum. In most cases, the problem is solved by software through changing the region in the application or flashing the voice module.

In this article, we will discuss all available localization methods in detail, how to safely change the anchor region, where to download Russian voice packets and what to do if the device stubbornly refuses to understand commands in its native language. Careful follow the instructions will help to avoid errors that can lead to blocking functionality.

Definition of the model and firmware version

The first step before any action is to accurately identify your device. Xiaomi Ecosystem’s range is huge, and localization methods for flagship lidar models and simple chaotic models can be drastically different. Incorrect version definition can lead to incompatible software installation.

Usually, the model information is on the bottom of the case, on a sticker next to the charging contacts or under the dust collector cover. You need to find an alphanumeric code, such as SDJ02ZM or Roborock S50. Also critical is the firmware version, which you can only recognize after you first connect to Wi-Fi.

To view technical information, run the Mi Home app, even if the interface is in a foreign language. The device icon usually contains the model name. By clicking on it, you will be taken to the main menu, where the top right corner often has a settings button (three dots). Inside the menu, look for the section with the device information where the firmware version is indicated.

• 🤖 Find a sticker on the bottom of the device to accurately define the model.
• 📱 Connect the robot to the Mi Home app to view the current version of the software.
• 🌐 Write down the region to which the device is currently attached.
• ⚙️ Check for updates in device settings before changing language.

It’s worth noting that some global versions of devices (Global Version) already have a built-in multilingual interface, and if the Settings menu doesn’t have a Language or Voice Package, then the language is tightly tied to the server region.

Change of region in the Mi Home app

The most common and secure way to change the interface language and voice notifications is to change the region in the user profile. The logic of the Xiaomi IoT cloud platform is built so that content (including language packs) is loaded depending on the selected country.

To do this, you will need a Mi Account. Go to the application profile, usually a Profile tab or an icon of a person. Find Settings (cogs) and select Region. In the list that opens, you must select the country corresponding to the desired language. For Russian, the "Russia" region is often suitable, but sometimes "Germany" or "Singapore" work more efficiently depending on the year of release of the device.

⚠️ Attention: If you change region, the list of your devices in the app may temporarily clear. Don't panic, just re-attach the robot vacuum cleaner by resetting the Wi-Fi on the device itself.

After the region change, the app can suggest that you update your device, which can take 5 to 15 minutes, the robot will download new voice files and update the menu text, and if the language remains the same after the reboot, try resetting the device completely to factory settings, holding the power and return buttons at the same time.

It’s important to understand that changing regions not only affect language, but also the availability of certain smart home features, and some scenarios may become unavailable when switching to servers in other countries.

Instructions for the installation of the Russian language

If automatic region change doesn't work, you'll need to manually install a language pack, a method most commonly used for Roborock and Dreame models that have open voice architectures, requiring accuracy and a stable Internet connection.

First, make sure that the robot is connected to a 2.4GHz Wi-Fi network. Go to the device settings in the Mi Home app. Find the Voice Settings or Voice Settings section. If there is no such section explicitly, it can be hidden under the General Settings menu. Inside, you will see a list of available languages.

Select "Russian" or "Russian" from the list. The app will start downloading files, at which point the robot can pronounce phrases in the downloadable language during the installation process.

In some cases, especially for older models, there may not be a standard list, then the "engineering menu" method is used, and you need to quickly press 5-7 times a certain button (often this is the on or home button) to activate the hidden mode.

Once installed, be sure to restart the device, which can be done through the app or physically: turn off the robot, wait 10 seconds and turn on again, and only after the restart, the changes will become fully effective.

Use of alternative applications

The official Mi Home app doesn’t always correctly display all settings for devices purchased outside the official retail, and in such cases, alternative clients with advanced functionality, such as VeSync, Dreame Home or modified versions of Mi Home (for example, from Vevs), come to the rescue.

Dreame Home is specifically designed for the Dreame sub-brand (which is part of the Xiaomi ecosystem) technology, which often has more flexible localization settings and allows you to choose the language regardless of the region of your account. Once you install the application and log in through Mi Account, the device can be determined automatically.

Modified versions of Mi Home (called “mods”) provide access to hidden system settings, which can force you to change the region of the device without reassignment, and download any language packs from the cloud, but using such applications carries security risks, since you share your account information with third parties.

• 📲 Dreame Home – optimal for vacuum cleaners of Dreame and Xiaomi brands.
• 🛠 Mi Home Mod (Vevs) – Advanced features for advanced users.
• 🌐 VeSync – suitable for some models produced under the Eufy or Tineco brand.
• ⚠️ The official app is the safest, but less flexible option.

When using third-party software, remember to periodically return to the official application to check for global firmware updates that may contain important security patches.

Table of compatibility of models and methods

Not all models support all of the methods described below, and here is a table that will help you navigate your device series, and it's relevant for devices released between 2020 and 2026.

Note that for models marked "Lite" or "C" (e.g. Mijia 1C), localization is often limited, and in such devices, the language can be hardwired into the controller's memory.

⚠️ Note: If your model is not in the table, it does not mean that you can not change the language. Try a universal method of changing the region to "China" and back, this often updates the configuration files.

Solution: Robot speaks Chinese

It's quite common for a robot to continue speaking Chinese after all the settings, and this can be caused by caching old files in the device's memory or by a server error when loading a packet.

The first thing you need to do is to force the network reset, press the Home and Power buttons (or Spot and Power, depending on the model) for 5-7 seconds at the same time until you hear a voice message about the Wi-Fi reset. Then reconnect the device in the application, making sure that the region has already changed to the desired one.

If that doesn't work, try the "deep discharge" method. Leave the robot running or just turn it on and leave it to run until it's completely turned off. Then put it on charge. When turned on after full discharge, some models initiate a system file integrity check and can tighten the correct language.

Also check if the Mi Home app itself is limited in language, sometimes the app interface is in Russian, but the settings inside take the language from the phone's system settings, and change the language of the smartphone to English, then Russian, to trigger an update of the app's language resources.

Updating voice packets manually

For advanced users, there is a way to manually replace voice files through the file system if the device supports FTP or Telnet access, a method that allows you to set custom voices or correct errors in official translations.

First, you need to activate debugging mode, and some models do this through a hidden menu (quick button press), others through special commands in the console, and once activated, you can connect to the robot from your computer.

The downloaded voice packet file (usually with the.pkg or.bin extension) is placed in the root directory or a special /miio/voice folder. After copying the file, you need to send a command to restart the voice engine or completely restart the device.

Example of commands for restarting voice service (for Linux models)



miio-service restart voice

Critically, only download voice packets from trusted resources, such as the official Xiaomi forum or the GitHub repositories of the OpenMiio community. Files from unverified sources can contain malicious code or damage the robot's file system.

This method provides maximum control, but requires high technical literacy, and a mistake in the name of the file or path can lead to the robot being left without a voice at all.

💡

Save the original voice file before you replace it. If the new package is not working, you can quickly return it to the same way you did, simply by renaming the files back.
