- Follow the on-screen instructions to connect the robot to your home Wi-Fi network.

2.4 Initial Mapping

3. Operating
3.1 Cleaning Modes
The robot vacuum offers multiple cleaning modes to suit different needs, adjustable via the Xiaomi Home app:
- Silent Mode: For quiet operation and light cleaning.
- Standard Mode: Balanced cleaning for daily use.
- Media Mode: Increased suction for moderate dirt.

3.3 Mopping Function
To use the mopping function, fill the intelligent water tank with clean water and attach the mopping pad. The intelligent water tank releases water uniformly to ensure consistent humidity without over-wetting the floor. Three different water settings are available for various floor materials.

3.4 Navigation and Cleaning Paths
The robot uses LDS laser navigation for precise positioning and accurate distance measurements, enabling it to create a detailed map of your home. It employs zig-zag and Y-shaped cleaning paths to ensure comprehensive coverage and simulate manual cleaning for effective stain removal.
