How to install Russian on the robot vacuum cleaner Xiaomi Mi Robot Vacuum 1S: all working methods

Xiaomi Mi Robot Vacuum 1S is a popular automated cleaning device, but many users are faced with a problem: the default interface and voice prompts in Chinese or English. Without Russification, it is difficult to control the vacuum cleaner through the Mi Home app, and voice alerts remain unclear. In this article, we will analyze all the current ways to change the language to Russian, including official and alternative methods, and also solve typical errors that occur in the process.

It is important to understand that the procedure depends on the firmware version and the region of the device binding in Mi Home. Some vacuum cleaners initially support Russian, but require the correct setting, others need manual updating or even flashing. We will consider options for all cases, including instructions for users with different levels of technical training.

If you just bought Xiaomi Mi Robot Vacuum 1S and see the characters on the app screen, do not rush to return the device to the store. 90% of the time the problem is solved in 10-15 minutes using our instructions.

Preparation: What to do before changing the language

Before you start setting up, make sure that the basic conditions are met:

• 📱 The latest Mi Home app update (at least 6.5.400) may not support Russification.
• 🌐 The device is connected to a Wi-Fi network with Internet access (the robot must receive data from Xiaomi servers).
• 🔋 The battery charge of the vacuum cleaner is at least 20.
• 📌 Mi Account is linked to Russia or Europe, and if your account is Chinese, the language will not change.

Pay special attention to the region of your account. If you bought a vacuum cleaner on AliExpress or in a Chinese store, chances are that the device is tied to Mi Account from the region of China (Mainland), in which case you will not be able to change the language through standard settings - you will need to reset and reassign to a Russian account.

Also check the vacuum cleaner firmware version.

1. Open Mi Home and select your robot vacuum cleaner.
2. Go to Settings. → About the device.
3. Find the firmware version string (for example, 3.5.9_0046).

If the firmware version is older than 3.5.8, Russian is already built into the system, and it remains only to activate.

Method 1: Change the language through the Mi Home app (official method)

This is the easiest and safest way to do this, and it works for most users, and it's relevant for 3.5.8 firmware and newer.

1. Open the Mi Home app and select your robot vacuum cleaner on the home screen.
2. In the list of available languages, select Russian (Russian).

After the reboot, all voice alerts and text prompts in the app will be in Russian, and if the robot language item is not on the menu, then your firmware does not support Russification through Mi Home, and you need to use alternative methods.

⚠️ Attention: If after changing the language, the vacuum cleaner starts speaking Russian, but in the application some of the inscriptions remain in Chinese, this is normal. Full Russification of the Mi Home interface depends on the version of the application and the region of the account.

Method 2: Update firmware to add Russian

If you don't have a language change option in your settings, you probably have outdated firmware, and then forced updates via Mi Home will help.

1. Open Mi Home and go to the vacuum cleaner settings (⋮ → Settings → About the device).
2. Click on the firmware update (or Firmware Update).
3. If an update is available, confirm installation, and it will take 5-15 minutes to complete, and you can’t interrupt it (the risk of building the device).
4. After the update, restart the vacuum cleaner and check for Russian in the settings.

If the update is not automatically available, try:

• 🔄 Reconnect the vacuum cleaner to Wi-Fi (sometimes network change helps).
• 📱 Reinstall the Mi Home app.
• 🌍 Change your account region to Russia (in the Mi Account profile settings).

⚠️ Warning: If the vacuum cleaner stopped turning on after the firmware update or if it gives an Error 12 error, it means that the update was incorrect, in this case, only a factory reset (press the power button for 10 seconds) and re-associating to the account will help.

💡

If the firmware update is 0% down, try connecting the vacuum cleaner to another Wi-Fi network (e.g., mobile internet via a smartphone in hotspot mode), sometimes the problem lies in the ISP blocking traffic.

Method 3: Manually update firmware through file (for power users)

If the official update doesn’t work, you can install the Russian firmware manually, which is suitable for firmware older than 3.3.8, but requires caution.

You'll need:

• 🖥️ Computer with Windows or macOS.
• 📁 Firmware file with support for Russian (you can download it on the XDA Developers or 4PDA).
• 🔌 USB-Type-C Cable for Connecting a Vacuum Cleaner to a PC.
• 🛠️ Mi Home Hack or Xiaomi ADB/Fastboot Tools.

Step-by-step:

1. Download the archive with firmware (for example, mirobot_vacuum_3.5.8_ru.zip) and unpack it.
2. Connect the vacuum cleaner to the computer via USB (the connector is under the cover of the case).
3. Start Xiaomi ADB/Fastboot Tools and select Manual Install.
4. Specify the path to the firmware file (.pkg or.zip) and wait for the installation to be completed.
5. After restarting the vacuum cleaner, check the tongue in Mi Home.

This is a risky way to do it: if you make a mistake, the vacuum cleaner can stop working, and only use it if other methods have failed.

Method 4: Resetting the vacuum cleaner and binding to the Russian account

If the vacuum cleaner is initially linked to a Chinese Mi Account, you can’t change the language, in which case a full reset and reassignment to a Russian account will help.

How to reset your settings:

1. Press and hold the power button on the vacuum cleaner for 10-15 seconds until you hear the beep.
2. After the discharge, the vacuum cleaner will issue a voice alert in Chinese (this is normal).
3. In the Mi Home app, remove the device from the list (click on the vacuum cleaner) → ⋮ → Remove the device).
4. Add the vacuum cleaner again by selecting the region of Russia when setting up.

After re-binding, check for Russian in the settings. If it is not available, update the firmware (method 2).

⚠️ Note: When reset, all stored room maps, cleaning schedules and custom settings will be deleted. Take screenshots of important settings in advance or export maps via Mi Home (if the feature is available).

💡

Resetting to factory settings is a last resort, but it is guaranteed to solve problems with binding to the wrong region. Once reset, the vacuum cleaner becomes "clean" and ready to be set up from scratch.

Solving Common Mistakes When Changing Language

Even following the instructions, users often face problems, and let’s look at the most common errors and how to fix them:

• 🔴 The error "No Russian language option" means that the firmware does not support Russian. Solution: update the firmware (method 2) or install it manually (method 3).
• 🔴 The vacuum cleaner doesn't connect to Wi-Fi after a reset - check that you're using a 2.4GHz network (the robot doesn't work with 5GHz.
• 🔴 The voice prompts are in Chinese -- even after changing the language in the settings, some models retain Chinese voiceovers.
• 🔴 Mi Home app does not find vacuum cleaner – make sure Bluetooth is on on your smartphone and the vacuum cleaner is in pairing mode (blue light flashes).

If none of the methods worked, check:

• 📋 Compatibility of the model: some parts Xiaomi Mi Robot Vacuum 1S (especially early ones) do not support Russian language at the hardware level.
• 🔧 Integrity of firmware files: download them only from trusted sources (e.g, 4PDA).
• 📡 Internet connection stability: with a weak Wi-Fi signal, firmware update may be interrupted.
