How to switch the language to Russian in the robot vacuum cleaner Xiaomi: all ways

Xiaomi’s robot vacuum cleaners are some of the most popular smart home assistants, but many users face a problem: after buying the device, the device speaks Chinese or English, and the menu is displayed in obscure characters. This is especially true for models bought on AliExpress or brought from abroad. In this article, we will analyze all possible ways to change the language to Russian, from simple (via the official application) to complex (flashing).

It is important to understand that not all models support Russian out of the box. For example, Xiaomi Mi Robot Vacuum-Mop 2 Lite or Dreame D9 often come with multilingual firmware, but older versions like Mi Robot Vacuum 1S may require manual intervention. We will look at solutions for different scenarios, including cases when the application does not see the vacuum cleaner or after updating the language reset.

If you’re just planning a purchase, look for the regional version of the device. Models labeled RU or Global in the title (e.g. Xiaomi Robot Vacuum-Mop 2 Pro RU) already have Russian by default.

1. Check the current version of the firmware and the model of the vacuum cleaner

Before you try to change the language, make sure your model supports Russian.

1. Check the firmware version through the Mi Home or Dreamehome app (Settings → About the device).

If the firmware version is older than 2021, there is a good chance that Russian is not available, in which case an update through alternative methods will be required (section 4).

⚠️ Note: If your model does not officially support Russian, trying to reflash the device may lead to loss of warranty or incorrect operation of sensors.

2. Change the language through the official Mi Home or Dreamehome app

The easiest way to change the language is to change it in the app, which works for most modern models (Mi Robot Vacuum-Mop 2 Pro, Dreame D10 Plus, etc.).

Instructions for Mi Home:

1. Open the app and select your vacuum cleaner.
2. Go to Settings → About the device → Language.
3. In the list, find Russian and save the changes.
4. Wait for the vacuum cleaner to restart (it will take 1-2 minutes).

For Dreamehome:

• 📱 Open the app and connect to the vacuum cleaner.
• 🔧 Slip on the gear icon (Settings).
• 🌐 Choose Device Language → Russian.
• 🔄 Confirm and wait for the update.

If there is no Russian in the list of languages, it means:

• 🔄 You have outdated firmware - an update is required (Section 3).
• 📦 Your model does not officially support Russian - see section 4.
• 🌍 The region in the application is incorrectly installed (must be Russia or Global).

⚠️ Note: After changing the language through the app, voice prompts may remain in Chinese. This is normal - the voice packet is updated separately (section 5).

3. Update of firmware to add Russian

If your vacuum cleaner doesn't have Russian, but the model supports it (see the table above), you probably need to update your firmware.

Method 1: Through Application (Automatically)

Many models (Mi Robot Vacuum-Mop P, Dreame D9) receive updates automatically, but sometimes the process gets stuck.

1. Open Mi Home or Dreamehome.

What to do if the update is not available?

• 📶 Check your Wi-Fi connection (the vacuum cleaner must be on the same network as the phone).
• 🔄 Restart the vacuum cleaner (hold the power button for 10 seconds).
• 📱 Update the Mi Home app to the latest version.
• 🌍 Make sure that the region of Russia is selected in the application profile.

Method 2: Manual installation of firmware through file

For models that don't automatically update (like the Viomi V3), you'll have to install the firmware manually, which is risky, because if you make a mistake, the vacuum cleaner may stop turning on.

Step-by-step:

1. Download the latest firmware for your model from the official Xiaomi or Dreame website.
2. Unpack the archive and rename the firmware file to miio.bin.
3. Copy it to an empty microSD card (FAT32).
4. Insert the card into the vacuum cleaner (the slot is usually under the cover).
5. Hold the power button for 5 seconds until the indicator flashes.
6. Wait until the end (the vacuum cleaner will emit an audible signal).

⚠️ Warning: Do not use firmware from third sites! Fake firmware files may contain malicious code that will turn off sensors or block the vacuum cleaner.

4. Alternative methods: flashing on custom firmware

If your model does not officially support Russian (for example, Xiaomi Mi Robot Vacuum 1S), the only option is to install custom firmware.

• 🔧 Requires disassembly of the vacuum cleaner (risk of sensor damage).
• 🚫 Cancels the guarantee.
• ⚡ It can cause unstable operation (e.g. navigation errors).

What you need:

• 🔌 USB-TTL adapter (e.g, CP2102).
• 💻 MiHome Hack or DustBuilder.
• 📄 Firmware with support for Russian (see forums like this) 4PDA).

Instructions:

1. Disassemble the vacuum cleaner and connect USB-TTL to the TX/RX/GND contacts on the board.
2. Launch DustBuilder and select the firmware file.
3. Follow the instructions of the program for recording.
4. After successful firmware, collect a vacuum cleaner and check the work.

💡

Before disassembling the vacuum cleaner, take a picture of all the cables and sensors, which will help avoid assembly errors and save time for diagnosis if something goes wrong.

If you're not sure about your skills, you'd better not take risks.

• 🛒 Purchase of a regional version of the vacuum cleaner (marked) RU).
• 📱 Using a real-time translator (e.g. Google Lens for crawling characters).
• 🔄 Contact the service center for an official update (sometimes they can flash Russian for a fee).

5. Customization of voice prompts in Russian

Even if you successfully change the interface language, voice prompts (e.g., “Cleanup Begins” or “Charge Completed”) can remain in Chinese, because the voice packet is loaded separately.

How to update voice prompts:

1. Open the Mi Home or Dreamehome app.
2. Go to Settings → Voice prompts.
3. Select Russian and wait for the download (can take up to 5 minutes).
4. Reboot the vacuum cleaner (turn off and turn on the power).

If the voice prompts have not changed:

• 🔄 Check your internet connection (voice packets are downloaded via the cloud).
• 📥 Remove the app cache (phone settings) → Annexes → Mi Home → Warehouse → Clear the cache).
• 🔊 Try to manually download the voice packet from the Xiaomi website (Downloads section").

💡

Voice prompts and the interface language are set separately, and even if the menu is in Russian, the voice can remain in Chinese until the package is manually loaded.

6. Problem Solving: The vacuum cleaner does not respond to a change of tongue

Sometimes, after all the manipulations, the language doesn't change. Let's look at the typical causes and solutions.

If nothing helps:

• 📧 Contact Xiaomi Support (via Mi Home app in Feedback section).
• 🔧 Try to reset the vacuum cleaner to factory settings (hold the power button for 15 seconds).
• 🛠️ If the device is warranty - take to the service center.

⚠️ Note: If after resetting the settings, the vacuum cleaner requires linking to the account of the previous owner (for example, after buying a used one), you will need to unlock through Xiaomi.
