Common mistakes and decisions:

⚠️ Note: If you use two-factor authentication in Mi Home, temporarily disable it while you connect. In some versions of the app, this causes conflict with Xiaomi servers.

3. First cleaning setup: map construction and calibration LDS

Once connected to Wi-Fi, the vacuum cleaner will prompt the first cleaning to build the map, which is critical, and it will determine the accuracy of navigation in the future.

The optimal conditions for the first launch:

• 🏠 The room should be well lit (but without direct sunlight).
• 🚪 All doors in the rooms that need to be removed should be open.
• 🪑 Remove small objects (wires, toys, shoes) from the floor – they can interfere with scanning.

The map construction process:

1. In the Mi Home app, click Cleanup → Start and select the Standard Mode.
2. The vacuum cleaner will spiral through the room, scanning the room, and don't interrupt the process, which can lead to an incomplete map.
3. Once you've cleaned it, you'll see a map in the app, check it for holes or distortions, and if the map is incomplete, start cleaning again.
