Xiaomi’s modern robot vacuum cleaners are famous for their ability to build detailed maps of the room, which greatly improves the efficiency of cleaning. However, over time, users may face the need to delete stored navigation data, this may be necessary when moving, seriously rearranging furniture or if the device has begun to “lose” in a familiar space.
The process of resetting the card varies depending on the specific model and version of the software installed in your gadget.In some cases, it is enough to simply clear the memory, and in others, you need to completely reset the navigation system settings through the mobile application.
In this article, we will take a closer look at all the mapping data removal methods available for the different Roborock and Mijia models, and learn how to avoid common errors and what to do if standard methods do not help restore the device to work properly.
Why you may need to delete the card
The main reason owners are looking for a way to reset the map of the Xiaomi Vacuum Mop vacuum cleaner is to change the layout of the apartment. If you have done renovations, removed partitions or, conversely, added new zones, the old algorithm of movement may become ineffective, the robot will try to avoid non-existent obstacles or, conversely, get stuck where it is now free.
Another common problem is the accumulation of errors in the navigation system: a laser rangefinder (LDS) or gyroscope can over time produce incorrect data that is recorded in memory. Memory cleaning allows the device to rescan the room from scratch, ignoring old, possibly erroneous coordinates.
⚠️ Warning: Before removing the card, make sure you have the option to re-clean the entire circuit to build a new one.Without the current map, the zoning and virtual walls function will not work.
Also, the reset is necessary when you sell the device or transfer it to another user, personal data about the layout of your home remains in the robot's memory, and its removal is a matter of digital hygiene and security. In rare cases, a software failure requires a complete reset of the configuration to restore communication with the base.
Preparing the device for resetting settings
Before you start taking drastic measures, you need to prepare the device. Make sure that the Xiaomi Mi Robot Vacuum is installed on the charging station and has sufficient battery power.The process of rebuilding the map is energy intensive, and a sudden disconnection in the middle of the cycle can damage the file system.
Check the cleanness of the sensors. The top laser unit (LDS) and the bottom sensors should be dust-free. If the sensors are contaminated, the new map can be built with distortion, and you have to repeat the procedure again. Wipe them with soft dry cloth.
- 🔋 Make sure that the battery is at least 80% before the procedure.
- 🧹 Clean the main brush and side blizzard of wound hair and debris.
- 📶 Check the stability of your Wi-Fi connection, as some commands are executed over the cloud.
It's also important to make room for maneuver, and although the robot can navigate obstacles by itself, it's best to remove wires, socks and other small objects that might confuse the wheels when calibrating a new route, which will allow for more accurate perimeter scans.
☑️ Preparation for card reset
Reset the card through the Mi Home app
The easiest and safest way to remove a Xiaomi vacuum cleaner card is to use the official Mi Home app. The interface may vary slightly depending on the account region, but the logic of action remains the same for most models, such as the Roborock S50, S5 Max or Mijia 1C.
Open the app and go to the home page of your device. Usually the map is displayed in the center of the screen. Click on the three dots in the upper right corner or look for the menu item that handles settings. You will need to find the section related to managing the card or memory.
Path to the menu: Settings → Map Management → Clear the mapIn some versions of the firmware, the option may be called Reset Map or Delete Card. Once clicked, the system will request confirmation of action. This is done to prevent accidental deletion of data. Accept the warning and the device will go into a new calibration waiting mode.
| Model vacuum cleaner | The Way to the Mi Home Menu | Do I need confirmation? | Time to reset |
|---|---|---|---|
| Roborock S5 / S50 | Settings → Map management | Yes. | Instantly. |
| Mijia 1C | Settings → Map | Yes. | Instantly. |
| Roborock S6 / S7 | Settings → Editing the map | Yes. | Instantly. |
| Xiaomi Vacuum Mop 2 | Settings → Map of the room | Yes. | Instantly. |
Once the command is completed, the robot will report by voice message (if supported) or by an indicator that the map is cleared, and is now ready to build a new route on its next launch.
💡
If you have multiple cards saved (for example, for different floors), delete them one by one by selecting the desired layer in the map management menu.
Use of the Roborock application
For Roborock devices (which are often more advanced versions of Xiaomi’s hardware), the Roborock app is a preferred choice, providing more flexible mapping tools, so you can not only remove the map completely, but also edit it, divide rooms or merge them.
To reset the card, go to the device settings in the app. Find the Map or Map Management section. Unlike the basic Mi Home, it often has a backup feature before deleting. This is a useful option if you're planning temporary interior changes.
Select the option Clear the map. The system will warn that all virtual walls, exclusion zones and room separation will be removed. Once confirmed, the robot will restart its navigation services, and the next time it starts, it will enter exploration mode, moving around the perimeter of the room.
⚠️ Attention: In the Roborock app, deleting the map also resets all customized cleaning scenarios tied to specific rooms.
If you use a model with a floorwashing function, such as the Roborock S7, make sure that after resetting the map, the areas with the carpets are correctly identified. The new map will not contain data on the types of coatings, and the robot may try to drive with a washing cloth on the carpet.

Alternative methods and reset via buttons
In situations where the application is not responding or the device is not connected to the network, an alternative approach may be required, but an important technical nuance is worth noting: most Xiaomi and Roborock models do not have a combination of buttons on the case to reset the card.
A long press of the on or home button usually results in either turning on/off, resetting the Wi-Fi module, or completely resetting the device to Factory Reset. A full reset will remove not only the card, but all settings, including account binding.
If you do decide to go for a full reset, find a hole that says Reset on the case (often next to the power button). Use the clip to press the internal button for 5-10 seconds. The device will report the reset and reboot.
- 🔄 Full Reset removes Wi-Fi settings and requires re-binding.
- 🗺️ Resetting the card through the application does not affect the system firmware files.
- ⚙️ Rebooting the device (off/on) does not delete the card, but only updates the current position.
Use the button method only in extreme cases when software methods are not available. For the usual cleaning of the map from layout errors, the application functionality described in the previous sections is sufficient.
💡
The Reset button on the case does a complete system reset, not just a card cleanup. To delete the card, use only software methods through the application.
Building a new map and calibration
Once you've cleaned the map of the Xiaomi Vacuum Mop, the device is ready to create a new one. Start the robot to clean completely. In this mode, it will move slower, carefully scanning the space with a laser or a camera.
Don't interrupt the cleaning process. Even if the robot has finished sucking up the dust, it must complete the perimeter bypass to precisely close the map contour. Interrupting can leave the map "torn" or unsurvive.
When you build a new map, make sure all the doors to the rooms are open (if you want them to be mapped) and the curtains are raised. Once you complete the cycle, the map will automatically be saved to the cloud and displayed in the app, and you can rename the rooms and set virtual limits.
⚠️ If after building a new map, the robot continues to behave inadequately (rests against walls, spins in place), check the serviceability of the laser module. LDS. It may have jammed or contaminated.
