How to install voiceover on the robot vacuum cleaner Xiaomi: from downloading files to firmware

Xiaomi Mi Robot Vacuum (including the S5/S6/S7, Mop 2 Pro and others) are often delivered by default with Chinese voiceovers or no Russian voice prompts, which creates discomfort: unclear commands, no feedback when errors or cleaning is completed. Fortunately, you can install Russian voiceovers yourself — and this does not always require a soldering iron or deep programming knowledge.

In this article, we will discuss all the current ways: from official updates through the Mi Home app to manual firmware through ADB or replacing files with micro-SD. Describe the nuances for different models, warn against typical errors (for example, firmware inappropriate voiceover version can cause a failure of the Wi-Fi module), and give a checklist to check the result. If your vacuum cleaner is silent or speaks in an incomprehensible language, here you will find a solution.

Which Xiaomi models support voiceover installation?

Not all Xiaomi robot vacuum cleaners allow you to change the language of voice prompts.

• 🔶 Not supported: Mi Robot Vacuum 1 (first generation), Viomi (separate line with other software).

To pinpoint the model, look at the sticker under the vacuum cleaner cover (e.g., STYJ02YM) or in the Mi Home app under Device → Settings → About Device. If your model is not on the supported list, Attempt firmware may result in a loss of warranty or device failure.

Method 1: Officially Update with Mi Home (Safeest Method)

Method 2: Manually upload voiceovers via micro-SD (for models with memory cards)

Many Xiaomi vacuum cleaners (such as the Mop 2 Pro) have a micro-SD slot where voice files can be uploaded.

• 📁 MicroSD memory card (up to 32 GB, formatted in the form of a microSD card) FAT32).
• 💻 Computer for downloading files.
• 🔗 Archive with voiceovers (choose a version for your model!).

Instructions:

1. Download the archive with voiceover (for example, ru_RU_STYJ02YM.zip foreground 2 Pro).
2. Unpack files in the micro-SD root (should be sound and voice folders).
3. Insert the card into the vacuum cleaner (the slot is usually under the lid next to the water tank).
4. Turn on the vacuum cleaner – it will automatically detect files and install them (update indicator will light up).

⚠️ Warning: Do not remove the memory card during installation (the indicator flashes blue). If the process is interrupted, the vacuum cleaner may freeze while booting - you will need to reset through the button. RESET (hold on).

Method 3: Firmware via Telnet/ADB (for advanced users)

If the official methods don’t work, you can manually flash voiceovers via Telnet or ADB, which is suitable for MT7688-based models (e.g. STYJ02YM).

• 🖥️ Computer with Windows/Linux.
• 🔌 Cable USB → Micro-USB (to connect to a vacuum cleaner).
• 📦 Package of utility for working with firmware.

Steps:

1. Connect the vacuum cleaner to the computer via USB (the connector is hidden under the cover).
2. Install the CP210x driver (download here).
3. Open PuTTY and connect via Telnet to 192.168.1.1 (port 23).
4. Enter the commands: cd /mnt/UDISK/ wget http://[link to archive with voice] unzip voice.zip reboot

⚠️ Attention: Incorrect commands in Telnet can erase the vacuum cleaner firmware. If the device does not turn on after rebooting, you will need to flash through the vacuum cleaner. UART (We recommend backing up the current firmware with dd if.=/dev/mtdblock0 of=/mnt/UDISK/backup.bin.

💡

Before you run through Telnet, disable the antivirus – it can block uploading files to the vacuum cleaner as “suspicious activity.”
