Xiaomi Vacuum Mop 2 is one of the most popular cleaning assistants, but its mapping functionality often raises questions among users. Many people face the problem: after rebooting or resetting the settings, the stored map of the room disappears, and the robot has to relearn how to plan the apartment. In this article, we will understand how to permanently store the map in the device’s memory, what settings are needed for this, and why sometimes the process does not go as expected.
It’s important to understand that Xiaomi Vacuum Mop 2 uses a laser rangefinder (LDS) to build a map, and its storage depends on firmware, the Mi Home app, and even regional servers. We analyzed official instructions, user reviews, and technical nuances to compile the most complete guide — without water or general phrases.
If you've just bought a robot, or you've been using it for months, but it's still resetting, you'll find a solution here, and if the problem is deeper (like hardware malfunctions), we'll give you a way to diagnose it.
Why the card in Xiaomi Vacuum Mop 2 is not saved: the main reasons
Before we get to the instructions, we'll figure out why the saved card might disappear, and that's a way to avoid the typical mistakes in the future.
The most common reason is that you don't have a Mi Account binding, and without that, you only store the card in the robot's local memory and reset it when you:
- 🔄 Reboot the device (for example, after updating the firmware).
- 🔌 Full battery discharge (if the robot has been off for a long time).
- 🔧 Reset settings to factory (Reset via button on the case).
Another common problem is an unstable Wi-Fi connection, the robot only syncs the map to the Xiaomi cloud when the Internet is active, and if the network goes missing during cleaning or saving, the data may not reach the server, and it also affects:
- 📶 A weak router signal (the robot loses communication in distant rooms).
- 🔒 Blocking traffic with firewall or parental controls.
- 🌍 Regional restrictions (e.g. if the robot is bought for China and used in Russia).
Finally, outdated firmware can lead to card saving bugs. 3.5.9_0040) There was a bug that caused the cards to be erased after the reboot, and we'll talk about that in the update section.
⚠️ Note: If the robot gives a Map save failed or Network error when trying to save, first check the Wi-Fi connection.
Preparing for saving the map: what to do in advance
To make it go smoothly, follow a few preliminary steps, which will take no more than 5 minutes, but will save you a lot of problems.
1. Update the Mi Home app to the latest version. Download it from Google Play or the App Store. Outdated versions may not support new mapping features.
2. Check the firmware version of the robot.
- Open Mi Home → Choose your robot.
3. Make sure the robot is connected to a stable 2.4GHz Wi-Fi network. Xiaomi Vacuum Mop 2 does not support 5GHz, and may also conflict with some router settings (for example, WPA3 or 802.11r enabled).
4. Clear the robot memory of old cards. If the application displays several saved plans (for example, from the previous apartment), delete them through Settings → Map → Delete all maps. This will help avoid confusion.
Step-by-step: how to save the card in Xiaomi Vacuum Mop 2
Now, to the main thing, you can save the map directly, and follow the instructions carefully so you don't miss important details.
1. Start a full cleaning. The robot has to go around all the rooms and build a full map. Don't interrupt the process even if it takes longer than usual to clean. You can choose the Full Cleaning mode in the app for reliability.
2 Wait until the map is completed. The Mi Home app will show the full plan of the room and rooms. If any areas are missed, send the robot to manually clean them through Area Cleanup.
3. Save the map to the cloud:
- 📱 Open the Mi Home app and select your robot.
- 🗺️ Go to the Map tab (usually at the bottom of the screen).
- 💾 Click on the Save icon (floppy disk or cloud, depending on the version of the application).
- 🔄 Wait for the notification Card saved.
4. Check the synchronization with the account:
- 👤 Make sure you are logged in to Mi Account (profile icon in upper right corner).
- ☁️ Go to Settings. → Cloud and check that the map sync function is enabled.
If done correctly, the map will remain in the robot's memory even after it's rebooted, but there are nuances that many people don't know about.

⚠️ Note: If the card is reset after saving, try to link the robot to another region in Mi Home. → Region. Choose Mainland China (even if you're not in China). Remove the robot from the list of devices and add it again. 70% As mentioned, outdated firmware is one of the main causes of card problems. There was a critical error in the older versions of the software: The robot only saved the card in RAM, which was cleared when it rebooted. 3.5.9_0040 (came out 2022 To update the firmware: Open Mi Home → Choose a robot → Settings → About the device → Firmware update.

If the app doesn't have an update button, try it: 🔄 Reboot the robot (hold the power button for 5 seconds). 📱 Reinstall the Mi Home app. 🌐 Connect to another Wi-Fi network (sometimes Xiaomi servers are blocked by the provider). After upgrading, check the firmware version again. If it is still old, it may be that your robot belongs to another regional version (for example, Xiaomi Vacuum Mop 2 Pro for China). In this case, you will have to search for firmware manually on forums (for example, 4PDA). 💡If the robot gets worse after the upgrade (for example, builds a map worse), try to roll back to the previous firmware version. To do this, download the old version from GitHub and manually stitch through Mi Home. Frequent errors and their solutions Even after saving the map correctly, problems can arise.

Additional tips for accurate mapping To make the map as accurate as possible and save it without errors, follow these recommendations: 1. Ensure good lighting. Xiaomi Vacuum Mop 2 uses not only a laser, but also a camera for navigation. In dark rooms, accuracy drops. 2. Remove small objects from the floor. Toys, wires or shoes can interfere with scanning, which makes the map fragmentary. 3. Use physical limiters. If the apartment has a robot, you can use a virtual zone, you can cover the camera with a transparent one. 4. Rub them with a soft wipe every 1-2 weeks. 5. Update the card every 1-2 months. If you rearrange the furniture or make repairs, start the robot to fully clean the map so that it rebuilt the map. 💡If the robot is constantly "losing" or skipping zones, check the laser settings in Mi Home. → Settings → Map. → Scan accuracy. Optimal value - High (but this increases cleaning time). FAQ: Frequently asked questions: Can you save the card without a Wi-Fi connection? Technically, yes, but it will only be stored in the robot's local memory and disappear after rebooting or draining the battery. How many cards can you save in Xiaomi Vacuum Mop 2?
