The smart robot vacuum cleaners Xiaomi and Roborock are famous for their ability to build accurate maps of the room and plan cleaning efficiently. However, over time or after rearranging the furniture, the navigation system can malfunction, leading to chaotic movement of the device or the inability to return to the base. In such situations, the only sure solution is to completely reset the accumulated data about the layout, which allows the device to rescan the space and build the optimal route.
The process of cleaning the memory of the card does not require special technical knowledge, but it is important to follow the sequence of actions so as not to knock down the basic settings of the connection to Wi-Fi. In this article, we will discuss in detail how to correctly reset through the mobile application and physical buttons on the case, and also discuss in which cases it is really necessary. Understanding the operation of the laser rangefinder (LDS) will help you avoid typical errors.
Often users confuse resetting the card with a full return to factory settings, which is a more radical step: Cleaning the map removes only the geometry of rooms and virtual walls, leaving network settings and a cleaning schedule intact. We will look at both options so you can choose the most suitable for your situation. carefully follow the instructions to make your Mi Robot Vacuum work again as new.
When you need to clean the room map
The main signal to action is the robot's inappropriate behavior during cleaning, and if your vacuum cleaner starts to "lose" in a familiar room, bump into obstacles that it has previously bypassed, or build routes that cross themselves, then the memory data has accumulated errors, and the laser navigator may have lost its way due to changes in light or the appearance of new objects that the system perceives as part of the wall.
Also, the reset is necessary when moving to a new apartment or after a major rearrangement of furniture, the old card will contain "dead zones" or, conversely, indicate the passageways that are now blocked by the sofa, trying to use old data in the new reality will lead to the robot being constantly stuck or trying to enter prohibited areas.
💡
Before resetting the card, take a screenshot of the current layout in the application if you need to save any specific areas for reference, although it will not be possible to restore them in the same form.
There are several clear signs that indicate the need for intervention:
- 🧹 Robot builds incorrect route, missing entire sections of the room.
- 🚫 The device can not find the charging station, although it is in its usual place.
- 🔄 The map in the application is displayed inverted or offset relative to the real position.
- ⚠️ The appearance of a message about a navigation error or failures in the operation of the gyroscope.
It's important to understand that the navigation system relies on the history of the movements, and if this story contains conflicting data, the logic of the algorithms is broken, and timely cleaning helps to refresh memory and eliminate software glitches associated with positioning.
Preparing the device for resetting settings
Before you start deleting data, you need to make sure that the vacuum cleaner is stable. The battery should be charged at least 20-30%, as the process of rearranging the map and calibrating the sensors can take time.
Make sure the robot is connected to a Wi-Fi network if you plan to control the process via a smartphone. Although resets can be done with buttons on the case, using the Mi Home or Xiaomi Home app gives you more control and allows you to immediately set up new virtual restrictions. Check that the laser rangefinder cover (LDS) It rotates freely and is not blocked by foreign objects.
You also need to get the room ready, remove wires, socks and other small objects that can get the wheels tangled, and to build a new map properly, the space should be as free as possible, and if you use magnetic tape to limit the zones, it's best to remove it for the time being, so that the robot can scan the clean geometry of the room.
Check the status of the connection in the application. If the device is displayed as "Offline", first restore communication with the router. Resetting the card on the disconnected device can lead to desynchronization of data, and you will have to re-associate the vacuum cleaner to the account.
Method 1: Reset via the Mi Home app
The most convenient and safe way to clean up your memory is to use an official control interface, which allows you to visually monitor the process and see the result immediately. Open the Mi Home app on your smartphone and select your robot vacuum cleaner card from your device list.
Once you enter the main control menu, go to the device settings. This is usually a three-dot icon in the top right corner of the screen. In the list that opens, look for the section associated with the map or navigation. In different versions of firmware, it can be called "Map Settings", "Map Management" or "Map and memory".
The algorithm of actions is as follows:
- 📱 Find the button "Clear the card" or "Reset the card" (Reset Map).
- ✅ Confirm the action in the pop-up warning window.
- ⏳ Wait for the message of successful deletion of data.
- 🗺️ Start a complete cleaning to build a new scheme.
💡
When reset via the application, Wi-Fi settings and cleaning schedule are saved, only the geometry of the room and virtual walls are removed.
Once confirmed, the system will remove all the stored floors and areas, the robot will go into the waiting mode of a new map, now it will need to drive through all the available area for the laser rangefinder (LDS) to read the contours of the walls, and it is recommended not to interrupt the first cleaning after reset, so that the device can build a model.
Method 2: Hardware reset buttons on the body
If the smartphone is not available or the app is not working properly, you can use physical buttons on the vacuum cleaner itself, a method that is universal for most Xiaomi and Roborock models, but requires accurate time intervals.
On the top of the device, find the on and back button (Home) that are often used to enter service modes. Some models require you to press both the on and off button (Spot cleaning).
Instructions for performing hardware reset:
- Turn on the vacuum cleaner and wait for the system to load.
- Press and hold the Home button and the power button simultaneously for 5-10 seconds.
- Listen to the voice message: the device will report the beginning of reset or transition to pairing mode.
- Release the buttons when you hear confirmation or see the flashing of indicators.
⚠️ Note: On some models, long-term button retention may trigger Wi-Fi pairing mode (Access Point) rather than resetting the card. If the robot starts announcing the access point, just restart it and try another combination described in the manual of your particular model.
After a successful operation, the indicators can turn orange, signaling readiness to build a new map, start cleaning so that the device starts scanning the space, which is especially useful if the application is “hanging” and does not send a command to clean.
Comparison of discharge methods and their features
The choice between software and hardware depends on your situation and device model, each with its own advantages and limitations that should be considered before starting the procedure.
The following is a table comparing the main characteristics of discharge methods:
| Parameter | Through the Mi Home app | Buttons on the case | Total reset (Reset) |
|---|---|---|---|
| Keeping Wi-Fi safe | Yes. | Yeah (usually) | No. |
| Deletion of the schedule | No. | No. | Yes. |
| Difficulty | Low. | Medium | Tall. |
| Risk of error | Minimum | Medium. | High-pitched |
The software method through Mi Home is preferred by most users because it is the safest and most understandable. Hardware reset is good as a backup. Hard Reset should only be used in extreme cases when the device has completely ceased to respond to commands, as it returns the vacuum cleaner to factory condition.
What happens to multi-layered maps?
Building a new map and calibration
Once the reset is successful, the most important step is to create a new map, and the robot must travel around the house to allow the laser rangefinder (LDS) to record the distances to the walls and corners, during which time it is not necessary to interfere with the device or try to move it to another room.
For high-quality calibration, follow the following recommendations:
- 🚪 Open all doors to rooms that need to be cleaned.
- 🪟 Provide good lighting so that optical sensors work properly.
- 🧹 Remove toys, wires and clothes from the floor.
- 🛑 Do not lift or carry the robot during the first cleaning after resetting.
The process can take longer than a normal cleaning, because the robot will move slower, scanning the perimeter carefully. In the app, you'll see the gray contours of the walls being built in real time. If the map is being built curved or with tears, it's possible that the laser sensor is contaminated.
⚠️ Warning: If you force the robot to stop or get stuck while building a new map, the map may be saved with errors.
Once the cycle is complete, the robot will automatically return to base and prompt you to save the map, and be sure to rename the floor (e.g., "1 floor" or "Apartment") so that the system understands that this is the main cleaning profile.
Frequent errors and ways to fix them
Even if you follow all the instructions, users can run into problems. One of the common mistakes is "The map is not saved." This can be due to an unstable connection to Xiaomi servers or a crowded memory of the device. Try restarting the router and the vacuum cleaner itself.
Another problem is shifting the map relative to the actual position of the furniture, which often happens if the robot was accidentally shifted during cleaning, in which case the "Recover Map" function (if available in the model) or reset with more careful preparation of the room helps.
☑️ Checklist before launching new map
If the robot is permanently losing contact with the base after resetting the card, check the contacts at the charging station. The terminals may have oxidized and the device simply cannot be properly positioned for charging, which is interpreted as a navigation error.
In rare cases, firmware updates help. Go to your device settings in the app and check for a new version of the software. Manufacturers often release patches that improve LDS algorithms and connection stability.
