Why Xiaomi’s Robot Vacuum Speaks Chinese and How to Fix It
You bought a Xiaomi Mi Robot Vacuum, MiJia or Viomi, but instead of Russian or English, it sends messages in Chinese? This is a typical problem for models not officially shipped to Russia or Europe. The manufacturer installs the default language firmware for the main market, China. However, there are several ways to fix this, and not all of them require technical skills.
In this article, we will discuss all the current methods of changing the language on Xiaomi robot vacuum cleaners, including: setting up through the Mi Home application, manual reset, firmware updates, as well as alternative solutions for outdated models.
⚠️ Important: Some methods (for example, firmware through the ADB) If your vacuum cleaner is warranty-free, try the official methods first, which are described in the first two sections.
Method 1: Change the language through the Mi Home app (official method)
The easiest and safest way is to use the Mi Home app, which is suitable for most modern models (Mi Robot Vacuum-Mop 2 Pro, MiJia 1C, Viomi V3, etc.), but there are nuances with regional limitations.
What you need:
- 📱 Smartphone with Mi Home app installed (you can download it from Google Play or App Store).
- 🔌 Robot vacuum cleaner connected to the same Wi-Fi network as the phone.
- 🔑 Xiaomi account (if not, register in advance).
Step-by-step:
- Open Mi Home and select your vacuum cleaner from the device list.
Check the version of the app (update to the latest one)
Make sure the vacuum cleaner is connected to the internet.
Reboot the robot (hold the power button for 10 seconds)
Change your Xiaomi account region to “Russia” or “Europe"-->
⚠️ Note: If there is no Russian in the list of languages, it means that your firmware does not support it out of the box, in which case only the firmware with a multilingual version or a reset to factory settings with a choice of region will help.
Critical information: On some models (e.g. Mi Robot Vacuum-Mop P), after updating the firmware through Mi Home, the language may reset back to Chinese. To avoid this, turn off automatic updates in the application settings before updating.
Method 2: Reset region-selecting settings (for multilingual models)
If your vacuum cleaner initially supports multiple languages but is stuck in Chinese, hard resetting with manual region selection will help, a method that works for most Mi Robot Vacuum devices (except the oldest models from 2016-2017).
How to perform the reset:
- Turn off the vacuum cleaner by holding the power button for 5 seconds.
- Press and hold the Home and Power buttons at the same time for 10-15 seconds until you hear the beep.
- Release the buttons – the vacuum cleaner will start the reset process (the indicator will flash orange).
- After the reboot, connect to the vacuum cleaner via Mi Home and select the region of Russia or Europe when you first start.
| Model vacuum cleaner | Does resetting support language selection | Notes |
|---|---|---|
| Mi Robot Vacuum-Mop 2 Pro | ✅ Yes. | After the reset, Russian and English are available |
| MiJia 1C | ✅ Yes. | Requires firmware not lower than 3.5.9 |
| Viomi V3 | ⚠️ Partially. | Russian appears only after linking to a European server. |
| Mi Robot Vacuum 1 (2016) | ❌ No. | Hand-held firmware required |
⚠️ Note: Some models may require re-assignment to Xiaomi account after reset.If the vacuum cleaner doesn't connect to Wi-Fi, check if the router is blocking devices from China (sometimes changing helps). DNS at 8.8.8.8).

Method 3: Firmware multilingual version of the software (for experienced users)
If the first two methods fail, the manual firmware of the alternative software version remains. This is a radical but effective way that is suitable even for older models (Mi Robot Vacuum 1, Mi Robot Vacuum 2).
What you need:
- 💻 Computer with Windows or macOS.
- 🔌 USB-Type-C Cable (to connect vacuum cleaner to PC).
- 📁 Firmware with support for Russian language (you can download on the forums) 4PDA or Xiaomi.eu).
- 🛠️ MiHome Hack or ADB (unlock).
Step-by-step (simplified version):
- Download the firmware for your model (for example, mirobot_vacuum_v11_4.6.1_0860_multilang).
- Connect the vacuum cleaner to your PC via USB and start the ADB (if required, activate the developer mode by holding the Spot Clean button when turned on).
- In the command line, run: adb push firmware.bin /tmp/ adb shell flash firmware.bin
- Wait for the firmware to be completed (the robot will restart automatically).
What to do if the firmware is interrupted?
⚠️ Attention: Firmware through ADB This can cause a loss of warranty, and on some models (Viomi) SE) after firmware ceases to work laser rangefinder is a well-known bug that is corrected only by rollback to the stock version.
Where to download the verified firmware?
- 🔗 Official multilingual builds: Xiaomi.eu Community.
- 🔗 Russian-language forums: 4PDA (topic).
- 🔗 GitHub: repositories like com.xiaomi.mirobot.
💡
Firmware is the last resort. Try resetting or changing the region in Mi Home first. If you're not sure about your skills, you'd better see a specialist.
Method 4: Use of alternative applications (for vacuum cleaners without official support)
If your vacuum cleaner doesn't support Russian even after you've been firmware, you can get around the restriction with third-party apps, which don't change the language of the device itself, but translate the control interface and voice prompts.
Top.-3 Applications for managing Xiaomi vacuum cleaners:
- 📱 MiHome (modified version) - supports forced change of region. 4PDA.
- 📱 Robot Vacuum Controller (for Android) – allows you to control the vacuum cleaner without being tied to Xiaomi servers.
- 📱 Home Assistant - for advanced users. Integrates with vacuum cleaner through MQTT and supports Russification.
How to set up MiHome (mod):
- Remove the original Mi Home app.
- Install a modified version (for example, MiHome_5.9.33_mod.apk).
- When you first start, select the region of Russia or Singapore (for the English interface).
- Connect the vacuum cleaner again – the interface language and voice prompts will change.
⚠️ Note: Alternative apps may not support all features (e.g. zoning or wet cleaning management).In addition, Xiaomi periodically blocks unofficial customers - if it stops working, try updating the version.
💡
If the vacuum cleaner is making voice commands in Chinese, but you only need a Russian interface in the app, turn off the sound in the device settings (Settings → Voice prompts → Off).
Method 5: Physical replacement of the voice module (extreme case)
On the oldest models (Mi Robot Vacuum 1, Mi Robot Vacuum 2 2016-2018), the software-based language change may not work, leaving the voice module, a small board inside the vacuum cleaner that handles the sound.
How it works:
- 🔧 Inside the vacuum cleaner is a speaker with a chip that reproduces voice prompts.
- 🔄 On AliExpress or in service centers you can buy a module with Russian / English voiceovers (cost) ~1000–1500 ₽).
- 🔨 Replacement requires disassembly of the body and soldering (or replacement of the connector, depending on the model).
⚠️ Attention: Self-disassembly of the vacuum cleaner is not guaranteed. If you are not sure about your skills, you should contact the service center. The average cost of replacing a module in the workshop is 2000-3000 ₽.
Where to buy the module:
- 🛒 AliExpress (see the Russian Robot Voice Module).
- 🛒 Groups in Telegram (for example, @xiaomi_robot).
- 🛒 Xiaomi service centers (the list can be found on the official website).
💡
Replacing the voice module is the only way to get Russian on vacuum cleaners from 2016-2018, but it is expensive and risky: not all modules are compatible with firmware.
Frequent Mistakes and How to Avoid Them
When changing languages on Xiaomi robot vacuum cleaners, users often face typical problems, and here are the most common ones and ways to solve them:
Problem 1: After resetting, the language is again confused into Chinese.
⚠️ Solution: This means that your firmware is tied to a Chinese server. Try: Change your Xiaomi account region to Russia or Singapore. Disable automatic software updates in the Mi Home settings. Install modified firmware (see the firmware section).
Problem 2: There is no Russian in the list of languages.
⚠️ Solution: Your model doesn't support Russian out of the box. Options: Use English (often a compromise solution); Sweep through alternative software (risky but effective); Buy a voice module with Russian voice acting.
Problem 3: After the firmware vacuum is not turned on.
⚠️ Solution: Probably the firmware is not suitable for your model. Try: Perform an emergency reset (hold the power button for 20 seconds); Swipe the stock version of the software. Contact the service center.
Problem 4: The Mi Home app doesn't see the vacuum cleaner after being dumped.
⚠️ Solution: Check: Is the vacuum cleaner connected to the same Wi-Fi network as the phone, is the router blocking the devices from China (try turning off the firewall), is the Mi Home app updated to the latest version.
