How to sew a robot vacuum cleaner Xiaomi: official and alternative ways

Xiaomi’s robot vacuum cleaner firmware is a procedure that can solve problems with the device, add new features or even unlock hidden features. However, improper actions lead to a “bricking” of the gadget, loss of warranty or failure of laser sensors. In this article, we will discuss all the current firmware methods for Mi Robot Vacuum, Mi Robot Vacuum-Mop, Xiaomi Robot Vacuum S10/S12 and others, including official updates via Mi Home, manual updates via ADB and alternative firmware like Valetudo.

It is important to understand the difference between the terms:

• 🔄 Update firmware – installing the official version of the software from Xiaomi through the application or manually.
• 🛠️ Firmware – replacing the current firmware with custom (for example, to remove cloud binding to Mi Home).
• ⚠️ Downgrade – rollback to the old version of the software (risky operation, can block the device).

If your vacuum cleaner is buggy, not building a map, or constantly losing Wi-Fi connectivity, firmware can help.

• ⚡ Battery charge (should be more than 50%).
• 📶 Internet connection stability (vacuum cleaner should not be disconnected from the router).
• 📱 Mi Home version (update to the latest in Google) Play/App Store).

5 Frequent firmware errors and how to fix them

Even if you follow the instructions, you can have problems, and let's look at the most common ones and how to solve them.
