How to change voiceover in the robot vacuum cleaner Xiaomi: official and informal ways

Xiaomi’s robot vacuum cleaners have become an integral part of smart homes, but standard voiceovers in Chinese or monotonous English often annoy users. Fortunately, you can change the assistant’s voice in several ways, from official settings in the Mi Home to deep flashing the device. In this article, we will analyze all current methods, including hidden functions, alternative firmware and manual replacement of audio files.

Many owners are unaware that their vacuum cleaner contains additional language packs or the ability to download custom voices. Z10 Pro or Viomi V3) They support dynamic voice changes directly from the mobile app, but there are pitfalls: incorrect firmware can cause sensor failures or loss of warranty.

If you’re just planning a purchase, note that new Xiaomi models (released after 2022) often don’t have the option of manual voice changes due to security policies, leaving you with either a standard voice or a workaround through third-party firmware.

1.Official method: changing the language in Mi Home

The easiest and safest method is to use the built-in settings of the Mi Home app, which is suitable for most models released after 2019, but has limitations: only the languages that the manufacturer originally laid down are available.

To change the voiceover:

1. Open the Mi Home app and select your robot vacuum cleaner.
2. Go to Settings. → General. → Voice language.
3. In the list, select the desired language (for example, Russian, English or Spanish).
4. Confirm the changes and wait for the device to restart (it can take up to 2 minutes).

⚠️

Note: On some models (e.g. Mi Robot Vacuum-Mop 2 Lite), changing the language in the app only changes the interface, not the voiceover, in which case an alternative method will be required.

Mi Home often updates the list of available languages. If you don’t have the right option, check the relevance of the version of the application in Google Play or the App Store. It is also worth noting that the voice of the assistant (for example, female / male) in the official firmware can not be changed, only the language.

💡

If after changing the language vacuum cleaner gives an error "Unknown command", try to reset the settings to the factory through Settings → General. → Reset. It helps 80 percent of the time.

2. Alternative firmware: how to install a custom voice

The installation process includes several stages:

1. Unlock root access via an exploit (e.g. mirobo.cain.xyz for older models).
2. Connection to the vacuum cleaner SSH (Use PuTTY or Termux).
3. Replacement of sound files in the directory /mnt/default/rockrobo/voice/ (format —.mp3 or.wav, bitrate no higher 128 quid).
4. Reboot the device with the reboot command.

🔧 Technical requirements for custom firmware:

• 📱 Rockrobo-based vacuum cleaner (Mi Robot series) 1S/2/3, Viomi V2).
• 🔌 Access to the local network (vacuum cleaner and PC must be in the same subnet).
• 🖥️ Computer with Python 3.8+ and the packages paho-mqtt, paramiko.
• 🔒 Disabled two-factor authentication in the Xiaomi account (can block access).

⚠️

Warning: Incorrect firmware can lead to loss of laser rangefinder functions (LDS) or navigation system failure. Before you start, back up the original firmware through the dd if command.=/dev/mtdblock3 of=/tmp/firmware_backup.bin.
