How to add Russian to the robot vacuum cleaner Xiaomi Mi: official and unofficial ways

Xiaomi Mi is one of the most popular cleaning assistants, but many users are faced with a problem: the interface and voice prompts by default in Chinese or English. This is especially true for models bought on AliExpress or in Chinese online stores. Without Russian, it becomes inconvenient to control the device through the Mi Home app (or Xiaomi Home) and voice alerts are completely incomprehensible.

Fortunately, you can add Russian in a number of ways, both officially (by changing the region in the application) and informally (by firmware alternative software).In this article, we will analyze all the current methods, including the nuances for specific models (Mi Robot Vacuum-Mop 2 Lite, S50/S51, STYJ02YM, etc.), and also warn against typical errors that can turn a vacuum cleaner into a “brick”.

If you are not sure about your technical skills, start with the simplest ways (sections 2–3). For advanced users, we have prepared instructions for manual firmware (section 5) and even recovery from failed manipulations (section 7).

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

Before you try to change the language, be sure to check the model of your vacuum cleaner and the firmware version, which will help avoid errors in choosing a method.

Method 1: Through the Mi Home app

Method 2: Through a physical button on the body

1. Press the power button on the vacuum cleaner for 5-7 seconds until you hear a voice alert.
2. The vacuum cleaner will name the model and the software version in English or Chinese. Write down what you heard.

⚠️ If your model is older than the Mi Robot 1S (2019, some of the techniques from this article may not be suitable. -Mi Robot 1, Mi Robot V1) Often a manual firmware is required through USB-OTG, which is risky without experience.

2.Official method: change of region in Mi Home

The safest and easiest method is to change the account region in the Mi Home app, which will allow you to download Russian firmware (if it is available for your model), the instructions are relevant for vacuum cleaners released after 2020 (S50/S51, STYJ02YM, Vacuum-Mop 2 Lite and later).

Step-by-step:

If there is no Russian language, update the firmware:

• 🔄 In the vacuum cleaner settings, find the Software Update and start the check.
• ⏳ Wait for the download and install of the update (can take up to 30 minutes).
• 🗣️ After the reboot, check the language of voice alerts – they should become Russian.

⚠️ Warning: If you change region, all automation and saved maps can be reset. Pre-save screenshots of settings or export data if possible.

💡

Changing the region to Mi Home only works for international firmware devices, and if your vacuum cleaner is Chinese (with the CN suffix in the model), this method will not work.

3. Unofficial method: firmware via Mi Home Mod (without root)

If the official method didn’t work, you can use a modified version of the Mi Home Mod app, which allows you to bypass regional restrictions and manually install Russian firmware, and is suitable for most models, including the Mi Robot S50 and STYJ02YM.

What you need:

Instructions:

1. Remove the original Mi Home app and install Mi Home Mod (allow installation from unknown sources).
2. Sign in to your Xiaomi account.
3. Add the vacuum cleaner to the app (if it has already been tied, reset via a 10 second button clamping).
4. Go to the device settings and find the Firmwer section.
5. Select Russian-language firmware from the list (for example, ru_3.5.8_0042) and press Update.

⚠️ Note: Firmware via Mi Home Mod can void warranty if the device was purchased from the official Xiaomi store. There is also a risk of an Update failed error - in this case, try again or use the method from section 5.

4. Manual firmware update via USB-OTG (for advanced)

If the previous methods did not work, the manual firmware remains through the USB-It's a technique that requires technical skills and is suitable for plug-in models. USB Type-C or Micro-USB (e.g. Mi Robot) 1S, STYJ02YM). The risk of “bricking” the device is high, so follow the instructions carefully.

Tools required:

• 🖥️ Computer with Windows/Linux.
• 🔌 Cable USB-OTG (or adapter for connecting the flash drive to the vacuum cleaner).
• 💾 A flash drive. FAT32 (32GB).
• 📁 [Firmware for your model](https://github.com/dontvacuum/mecloud) (Choose a version marked ru).

Step-by-step:

1. Download the firmware archive and unpack it. You need a file with the.pkg extension.
2. Copy this file to a flash drive (file name should remain unchanged!).
3. Connect the flash drive to the vacuum cleaner via a USB-OTG adapter.
4. Press the power button on the vacuum cleaner for 10 seconds until the indicator flashes.
5. Release the button and the update process will begin (the indicator will burn in orange).
6. Wait for the reboot (up to 15 minutes). Then turn off the flash drive.

Critical information: If the vacuum cleaner does not respond after the firmware (it does not turn on, does not make sounds), try to repeat the process with another version of the firmware. If this does not help, see section 7 on recovery.

5. Alternative methods: voice packets and third-party applications

If the firmware didn’t help or you don’t want to take risks, you can add Russian only for voice alerts.

Method 1: Valetudo utility (for models with support)

Method 2: Robot Vacuum Controller

⚠️ Note: Using third-party firmware (Valetudo) may disrupt laser sensors on some models. Check compatibility on forums (e.g., before installing the device, 4PDA).

7.Vacuum cleaner recovery after failed firmware

If you've been manipulated, the vacuum cleaner stops turning on or it makes an error, don't panic, and in most cases, it can be restored.

Step 1: Hard discharge

• 🔄 Press the power button for 20 seconds until the indicator flashes red.
• 🔌 Connect the vacuum cleaner to the base and wait for full charging (at least 2 hours).
• 🔄 Repeat the switching attempt.

Step 2: Re-firmware via USB

• 💾 Download the original firmware for your model from [official repository](https://github.com/dontvacuum/mecloud).
• 🔧 Repeat the process from the section 4, Use a stable version of the software (for example, 3.5.8_0042 for S50).

Step 3: Contacting the Service

• 🛠️ If the vacuum cleaner does not respond to the reset, contact the Xiaomi service center.
• 💰 Cost of recovery after a failed firmware: 1500-3,000 rubles (depending on the model).

⚠️ Note: If the vacuum cleaner was purchased in China (version) CN), Xiaomi Russia official service may refuse warranty repairs, in which case look for private workshops.

💡

Before you go to the service, try to find on forums (for example, 4PDA) users with the same problem. Often there are informal solutions, such as firmware through UART (requires solders).
