Step-by-step guide: how to build a map of an apartment for a robot vacuum cleaner Xiaomi Vacuum Mop

Xiaomi Vacuum Mop (including the S10, S12, X10+ and others) can turn cleaning into an automatic process — but only if it correctly “understands” the layout of your home. The map of the room is the basis of its work: its accuracy depends on how effectively the device will avoid obstacles, cover all areas and return to the base. However, many users face problems: the robot “lost”, builds a map chaoticly or ignores individual rooms.

In this article, we'll look at not only the basic steps to create a map, but also the hidden settings that will help optimize the process, how to prepare your apartment for scanning, what parameters in the Mi Home app affect the quality of the map, and what to do if the robot persistently "does not see" part of the room, and how to save and edit the map so that you do not start over again after resetting.

Preparation of the apartment before building a map

Before you start the robot, make sure the room is ready for scanning, and errors at this point lead to distorted maps that are difficult to fix.

• 🧹 Remove small objects from the floor: wires, toys, shoes. The robot may get stuck or misinterpret them as walls.
• 🚪 Open all doors to rooms that need scanning. Closed doors will create blind spots».
• 💡 Provide good lighting. Even if the model has LiDAR, the lack of light can distort the data from the additional sensors.
• 🪑 Lift curtains and curtains to a level above 30 cm from the floor – the robot can mistake them for obstacles.

Pay special attention to reflective surfaces: mirrors, glass tables or glossy laminate can knock down a laser scanner. If there are many such surfaces in a room, temporarily cover them with a cloth. Also check if there are infrared sources in the room (for example, heaters) - they interfere with the work of some sensors.

💡

If you have a staircase without a fence, install a virtual wall in the Mi Home app in advance, which will prevent the robot from falling during the scan.

Starting the first scan: step-by-step instructions

Now, to the process of mapping, the important thing is that the first scan should be as accurate as possible, so don't interrupt it or carry it manually.

1. Install the robot on the charging base and wait for full charging (at least 80%).
2. Open the Mi Home app, select your vacuum cleaner and go to the Map section.
3. Click Start Cleaning and select Full Cleaning (or Scan if such mode is available in your model).
4. Wait for the robot to go around the room, which can take anywhere from 20 minutes to 1.5 hours depending on the area.

When you scan, you can follow the process in real time through the app. If the robot is stuck or spinning around for a long time, don't pick it up -- you'd better wait for it to find its way out, or you can press Back to base and restart the process.

Optimization of the map: editing and zoning

After the first scan, you'll get a rough version of the map, and now you need to refine it.

• 📏 Divisions into rooms: click Edit → Separate rooms and draw lines along the boundaries of the premises.
• 🚫 Add no-go zones: Mark areas where the robot cannot go (e.g., near pet bowls).
• 🔄 Combining zones: if the robot divided one room into several parts mistakenly.
• 📍 Virtual Wall Installation: To Block Passages Without Physical Barriers.

An important nuance: if your model supports multi-storey maps (for example, Xiaomi Vacuum-Mop 2 Pro), save individual maps for each level.

1. Build a map on the first floor and keep it.
2. Move the robot to the second floor, start a new scan.
3. In the app, select Add Floor and assign the map a name (e.g., “2nd Floor”).

Common mistakes and their solutions

Even with the right preparation, problems can arise, and here are the typical scenarios and ways to fix them:

If the problem persists, try resetting the map and starting over again. Go to Settings → Map → Reset the card. Remember that after resetting, all saved areas and forbidden areas will have to be reconfigured.

Saving and backing up the card

To avoid losing settings after a firmware reset or update, keep your card backups regularly. The Mi Home app does this:

1. Open the Map section.
2. Click on the three dots in the upper right corner and select Export card.
3. Save the file to the cloud or locally to your phone.

For recovery:

1. Go to Settings → Map → Import cards.
2. Select the saved file.
3. Confirm the download and wait for the synchronization.

⚠️ Warning: The imported map may not match the actual layout if you rearranged the furniture, in which case the robot will build a new map over the old one, leading to navigational errors. Always check the relevance of the map after importing it!

Additional settings for accurate navigation

In addition to the basic map, Mi Home has hidden parameters that improve the work of the robot:

• 🎯 Sensor calibration: in some models (e.g. Xiaomi Mijia) 1T) LiDAR Calibration option available in Settings → Extra, run it every 3 months.
• 📶 Wi-Fi setting: If the signal is weak, the robot may lose communication and reset the map. Use a repeater or mesh system.
• 🔋 Power saving mode: turn it off in settings so that the robot does not interrupt the scan due to low charge.
• 🔄 Auto-Update Card: Enable this option if the layout changes frequently (e.g. in the office).

For supported models 3D-scanning (e.g. Xiaomi CyberDog or Vacuum-Mop) T10+) Extended functions available:

• Scanning furniture by height (useful to avoid collisions with low sofas).
• Recognition of surface types (carpet, tile, parquet) for automatic adjustment of the suction force.

💡

If your robot supports you SLAM-navigation (simultaneous localization and mapping), turn it on in the settings, which will speed up the scanning process by 30-40% without losing accuracy.
