Xiaomi Mi Robot Vacuum Mop Essential: instructions with photos and videos

Xiaomi Mi Robot Vacuum Mop Essential is a procedure that can solve navigation problems, add new features, or even “resuscitate” the device after a failure. However, improper actions lead to a blink (complete inoperability) or loss of warranty. In this article, only proven methods from official sources and enthusiasts who have been tested on models are presented. STYJ02YM and STYTJ02YM (Chinese and Global Version respectively).

Many users are faced with having to flash the vacuum cleaner after buying a “Chinese” version for Russification or when errors like Error 12 (a problem with sensors) appear. Others want to install custom firmware (for example, Valetudo) to work without the Xiaomi cloud. We will discuss both options - from automatic update via Mi Home to manual stitching through the ADB or SSH.

Before you start, answer two questions:

1. Why do you need firmware? (Error correction, new features, Russification, decoupling from the cloud?)
2. Are you ready to risk losing your warranty? (Official updates keep the warranty, custom ones don’t).

1. Firmware Preparation: What to Do Before You Start

2. Go to Settings. → About the device.
3. Write down the model (STYJ02YM or STYTJ02YM) and the P.O. Version.

The second is to ensure that you have stable power. The robot has to be at least 50 percent charged, or better, 100 percent charged, and if the firmware is interrupted by a discharge, it's very difficult to restore the device, and connect the vacuum cleaner to the charging station during the procedure.

Third, prepare the tools:

• 📱 Smartphone with Mi Home (latest version) or PC with Mi Robot Vacuum Tool.
• 🔌 USB-Type-C Cable (for manual firmware).
• 📁 Firmware file (official or custom).
• 🔧 Screwdriver (if you need to disassemble to access the UART).

Fourth, back up your settings. Mi Home doesn't have a customization export function, so take a picture.

• Cleaning schedule.
• No-go zones and virtual walls.
• Suction settings and wet cleaning.
