The Xiaomi Vacuum Mop Essential series of cleaning robots use laser navigation to build an accurate plan of the room, but over time, errors or unnecessary data can accumulate in the device’s memory. The situation when the robot begins to get confused in an already familiar room or build incorrect routes is often solved by completely cleaning the map. Understanding how to reset the map of the Xiaomi Vacuum Mop Essential vacuum cleaner is necessary for each owner to maintain the efficiency of cleaning.
There are several reasons why it may be necessary to interfere with the device’s navigation system, such as moving to a new apartment, relocating heavy furniture, changing the layout, or simply a software glitch that led to the “sticking” of old coordinates. Unlike more complex models, the Essential version has its own Mi Home app features, which are important to consider when performing a reset.
In this guide, we will take a look at all the ways to clean navigation data, how to safely remove a current map through your smartphone interface, what to do if the application does not respond, and how to properly configure the device again to avoid repeating errors.
Reasons for the need to reset navigation data
The main reason for performing the reset procedure is the accumulation of logical errors in the device's memory. The robot vacuum cleaner constantly scans the space, and if it encounters an obstacle several times that the application considered temporary, and in fact it has become permanent (for example, a new cabinet), it can knock down the route algorithms.
And you also need to clean up when you reconfigure the room, if you combine two rooms, if you dismantle the wall, if you build a partition, the old map will become irrelevant. The robot will try to drive through non-existent passageways or, conversely, stubbornly ignore new areas, in which case a complete remodel of the map from scratch will ensure that all functions, including virtual walls, work correctly.
Another factor is a software error where the device forgets its location or loses connection to the base, often solved by a simple restart, but if the problem is repeated, a deep reset of navigation data helps to return the system to a stable state.
- 🏠 Redevelopment of an apartment or rearrangement of large furniture, changing the geometry of rooms.
- 🔄 Persistent positioning errors or loss of connection to the base.
- 🧹 Robot vacuum cleaner move to new housing with a completely different layout.
- ⚙️ Mi Home app malfunctions after firmware update.
⚠️ Warning: Before resetting, make sure you save screenshots of the no-access zones if you have them manually configured, as it will be impossible to restore them after deleting the card.
Preparation of the device and application for cleaning
Before you start deleting data, you need to do a number of preparatory steps: First, make sure that your smartphone and robot vacuum cleaner are connected to the same Wi-Fi network. A stable connection is critical, since the reset command is transmitted through a cloud server or local network.
Second, check the battery power. It's desirable to have a charge level of at least 20 percent, although the deletion process itself doesn't require much energy. However, if the robot decides to calibrate or update the data during the reset, the low charge can interrupt the operation.
Finally, open the Mi Home app and make sure it works correctly. If the app is hanging or not loading the status of the device, try restarting the smartphone. The clean cache of the app will help avoid errors when executing control commands.

Before resetting the card, it is recommended to clean the dust container and wipe the sensors so that the robot begins a new navigation with clean sensors.
Delete the card through the Mi Home app
The easiest and safest way to reset the card is to use the regular functionality of the Mi Home application, which is suitable for most users and does not require technical knowledge.
To start, open the app and go to the main control screen of your Xiaomi Vacuum Mop Essential device. Usually, the room map is displayed in the center of the screen or is available from the cleaning history view button. You need to find the map settings menu, which is often hidden under an eye icon or three dots.
In the menu that opens, select the option “Maps Management” or “Maps Editing” and here you will see a list of saved cards (if there are several) and the current active one. Click on the delete button or basket next to the desired card. The system will ask you to confirm the action, as it is irreversible.
☑️ Algorithm for deleting the card
Once confirmed, the robot vacuum cleaner will be instructed to clean up the internal memory associated with navigation, and on the smartphone screen, the map will disappear, and the cleaning status will change, and the device is now ready to build a new room plan.
Alternative methods of resetting settings
If the standard method through the application does not work due to the interface freeze or loss of communication, you can try alternative options, one of which is a complete reset of Wi-Fi settings, which often leads to a clearing of temporary card data.
To do this, you need to simultaneously press two buttons on the vacuum cleaner body: the on button and the home return button (or the local cleaning button, depending on the modification). Hold them for 5-7 seconds until the device emits an audible signal or announces the transition to pairing mode.
After that, the robot will reboot, and it will have to be re-introduced as a new device, and when you first set up the system will suggest creating a new map, which is more radical, because it resets the network settings as well.
| Resetting method | Difficulty | Impact on Wi-Fi settings | Recommended scenario |
|---|---|---|---|
| Through the Mi Home app | Low. | It doesn't. | Planned cleaning, rearrangement of furniture |
| Resetting Wi-Fi (buttons) | Medium | Total reset | Application fails to respond, communication loss |
| Power outage | Low. | It doesn't. | Minimum buffer reset (rarely helps) |
⚠️ Note: When reset via button retention, the device will go into standby mode. Remember to re-enter your Wi-Fi network password in the app.
Building a new map after resetting
Once you've successfully deleted old data, you need to create a new map, and then you need to run a robot vacuum cleaner to clean it completely, and make sure that all the doors to the rooms are open, and there's no foreign objects on the floor, such as wires, clothes or toys.
Xiaomi Vacuum Mop Essential will zigzag the room, scanning the space with a laser rangefinder (LDS), which will display the plan under construction in real time on the smartphone screen. Do not interrupt the cleaning until the robot returns to base or clears all available area.
If you notice that the robot is missing sections or misdefining boundaries during the construction of a new map, let it complete the cycle. Often, rewiring helps the system adjust the data and comb the map, and once completed, you can rename the rooms and adjust the virtual walls.

Frequent mistakes and ways to solve them
Even if all instructions are followed, users may encounter typical problems, one of the most common is that the card is not saved after cleaning, which may be because the robot did not return to base on its own and the process was not completed correctly.
Another common mistake is to break the map into multiple pieces, which happens if the robot can't drive under the sofa or through a narrow opening, and the algorithm decides it's different rooms, in which case manually combining the rooms in the map editor or re-starting the cleaning with the doors open helps.
Also worth mentioning is the problem with phantom obstacles, where if the robot is constantly driving around a non-existent object in the middle of the room, maybe there was furniture in that place before and the data was recorded in cache, in which case a reset of the card is mandatory.
- 🚫 Map not saved: make sure the robot completes the cleaning and returns to base.
- 🔀 Map gap: check the passages between rooms and the height of the sills.
- 👻 Phantom walls: perform a complete reset and start cleaning in bright light.
💡
The quality of the new map depends on the cleanliness of the sensors and the absence of temporary obstacles on the floor during the first launch after reset.
Tips for caring for the navigation system
To keep your Xiaomi Vacuum Mop Essential running for a long time and without errors, it is important not only to be able to reset the map, but also to properly maintain the navigation system. Regularly wipe the top laser unit from dust, as these are the eyes of your robot.
Avoid mirrored surfaces and black glossy flooring if possible, as they can knock down distance sensors. If there are many such surfaces in the house, using virtual walls will help limit the robot’s area of operation and prevent loss of orientation.
Check firmware updates in the Mi Home app periodically. The company’s engineers are constantly improving navigation algorithms, and new versions of the software often contain patches for mapping and positioning bugs.
