Why does the Chinese version of Xiaomi Vacuum 1S not support Russian out of the box?

You bought a Xiaomi Mi Vacuum Cleaner 1S version of CN and you had a problem: the Mi Home app shows characters, voice hints in Chinese, and you don't have a language change option in the settings? You're not alone. The fact is that the devices for the domestic market of China (CN) are initially blocked under regional restrictions, the manufacturer configures them for local Xiaomi servers, where only Chinese and English are available by default.

But the good news is that you can get around this limitation without flashing or hacking, and you just need to change the region in the app and update the firmware through official channels. In this article, we'll look at all the working methods, including the nuances of Mi Home, Mi Home Lite and alternative firmware, and we'll also explain why, after a change of region, a vacuum cleaner can "forget" the maps of the premises and how to avoid this.

⚠️ Note: If after changing the region vacuum cleaner ceased to appear in the list of devices, check:

  • πŸ”Œ Is it connected to the same Wi-Fi network as the smartphone.
  • πŸ“Ά Does the firewall or antivirus block the connection to Xiaomi servers.
  • πŸ”„ Try restarting the router and vacuum cleaner (hold the power button for 10 seconds).

Method 2: Manual firmware update via Mi Home Lite

If the first method didn’t work (for example, there is no option to change the language in the settings), try updating the firmware through the alternative application Mi Home Lite. It often offers fresh versions of firmware, where Russian is already sewn in.

Algorithm of action:

  1. Remove Mi Home and install Mi Home Lite (available for Android only).
  2. Sign up with the same Xiaomi account.
  3. Add the vacuum cleaner again (the region will automatically be installed in China).
  4. Go to the device settings β†’ Update the firmware.
  5. If a new version is available, install it (the process will take 5-15 minutes).
  6. After updating, check the language section - Russian should appear.
What to do if the update is suspended?
If the firmware is stuck during the booting phase (more than 30 minutes), do not turn the vacuum cleaner off from the power! Try: 1. Reboot the router. 2. Connect the smartphone to the mobile Internet (sometimes Wi-Fi blocks traffic). 3. Remove the vacuum cleaner from the Mi Home Lite and add again. If nothing helps, reset the device to the factory settings (hold the power button 20 seconds before the beep).

πŸ“Œ Useful tip: If after the update the vacuum cleaner began to β€œglutch” (does not build a map, does not respond to commands), reset settings:

  1. Open Mi Home β†’ vacuum cleaner settings β†’ Additional β†’ Resetting settings.
  2. Confirm the action (the vacuum cleaner will emit a long signal).
  3. Connect it again - the language will remain, and the firmware problems will disappear.

Method 3: Alternative firmware (for advanced users)

If official methods fail, you can install custom firmware with Russian, which is suitable for users willing to risk the warranty (but gives more options, such as integration with Home Assistant).

The following are the Xiaomi Vacuum 1S firmware:

  • πŸ› οΈ Valetudo – open firmware with support for Russian and without reference to the cloud Xiaomi.
  • 🌐 DustBuilder - modified software with advanced map and cleaning zone settings.

⚠️ Attention: Installation of custom firmware:

  • πŸ”§ Requires unlocking the bootloader (the procedure is more complicated than updating through Mi Home).
  • ⚠️ Deprives of warranties (if vacuum cleaner on warranties, it is better to use official methods).
  • πŸ”„ It can cause loss of functions (such as voice assistant Alice).

If you are, here is a quick guide for Valetudo:

  1. Download the firmware from the official repository.
  2. Connect the vacuum cleaner to the PC via USB (you will need a USB-Type-C adapter).
  3. Use the utility mirobo.py to download the firmware:
python mirobo.py -d <IP- vacuum cleaner address> -t custom -f valetudo.bin
