Xiaomi Mi Robot Vacuum Robot Cleaner G1 (also known as Viomi V3 In some regions, it comes with Chinese firmware by default, which creates problems for Russian-speaking users: there is no localization of the menu, voice prompts in Chinese, and the Mi Home application may incorrectly display statuses. Firmware in Russian solves these problems, but requires accuracy – wrong actions can turn the device into a “brick».

In this article, we will analyze all available methods of Russification: from official updates through the application to alternative methods using custom firmware. We'll focus on risks (loss of warranty, locking of the device) and preparation — without it, even the right firmware can end up in error.

• 📋 Current firmware version: Chinese versions are often labeled as CN (for example, 3.5.8_000123.CN). Russian firmware has markings RU or EU.
• 🔒 The status of the bootloader lock: some batches G1 After 2022, they have a locked bootloader, which makes firmware impossible without an official unlocker from Xiaomi.

If your vacuum cleaner is purchased in Russia through official distributors (M.Video, Svyaznoy), most likely, it already has Russian firmware. Check this in the Mi Home app: go to the Device Profile → Settings → If there's a software version RU or EU, firmware not required.
