Today’s Xiaomi-branded robot vacuum cleaners and their sub-brands, such as Roborock or Viomi, are famous for their advanced LDS-based navigation system. These devices build a detailed map of your home, allowing them to clean more efficiently and faster each time, but sometimes there are situations when the accumulated layout data becomes incorrect, such as after rearranging furniture or changing the configuration of rooms.
In such cases, the user needs to know how to flip the map of the robot vacuum cleaner Xiaomi, so that the device can build a new, relevant model of space. the process of deleting navigation data is not complicated, but requires care, since it affects all saved settings, including virtual walls and forbidden areas. In this article, we will discuss in detail all methods of cleaning the device’s memory.
It's worth noting that resetting a card often solves problems when a robot "lost" in a familiar room or starts to randomly rush around the apartment. Laser sensor can conflict with outdated data, so periodic recalibration or a complete reset is a normal part of maintaining a smart app. Let's look at how to perform this procedure correctly through a mobile application.
When you need to delete the navigation map
The main reason for the forced removal of the map is a change in the geometry of the room. If you have combined rooms, dismantled partitions or, conversely, erected new walls, the old configuration file will prevent the robot from building optimal routes, in which case the navigation system will try to match reality with an outdated pattern, which will lead to positioning errors.
Another common problem is a software glitch, where the map is stored with distortions, the robot can "forget" part of the apartment or draw walls where there are none, and removal is necessary if you sold an apartment or moved to a new house and want to use the device from scratch. In some cases, just saving the current card helps, but if the errors are critical, a complete reset is required.
- 🏠 Complete redevelopment of living space or reshuffling of large furniture.
- 🤖 Failures in operation LDS-sensors that lead to incorrect route construction.
- 🔄 Change of device owner or move to a new location.
- ⚠️ Accumulation of software errors affecting cleaning accuracy.
⚠️ Warning: Before removing, make sure you have the option to reconfigure virtual restrictions, as after resetting, all No-Go zones will be erased without recovery.
Preparing the device for resetting settings
Before you start taking drastic measures, you need to make sure that the robot is ready for the procedure. First of all, check the battery charge. The process of rebuilding the map can take considerable time, especially if the space is large, so the charge level should be at least 60-80%. If the battery is discharged, put the device on the charging base until full saturation.
It is also critical to ensure a stable connection to the Wi-Fi network. All card manipulation is done through the cloud servers of Xiaomi Cloud, and the connection break at the time of deleting the file can lead to desynchronization of statuses between the application and the robot.
💡
Before you start any manipulation of the map, take a screenshot of the current layout in the application, which will help you quickly recreate virtual walls and forbidden areas after reset.
It is not superfluous to carry out preventive cleaning of the navigation sensor itself. On the top of the device is a rotating LDS unit, which should not have visible dirt or hair. Wipe the sensor with dry soft cloth to exclude mechanical errors when scanning a new map.
Delete the card through the Mi Home app
The most common and safe way to clear the navigation memory is to use the official Mi Home app (or Xiaomi Home).The program interface may vary slightly depending on the OS version and region, but the logic of action remains the same for all models. Open the app on your smartphone and go to the main device control screen.
Find your robot vacuum cleaner in the list and click on its icon to log into the control menu. The top right corner of the screen usually has a three-dot menu or settings icon. Click on it to expand the list of options available. You are interested in the section associated with the map or cleaning settings.
In the menu that opens, look for “Map settings” or “Map management” and display the current stored layout. To remove, click on the “Clear map” or basket icon. The system will request confirmation of the action, warning of the irreversibility of the process.
☑️ Pre-reset check
Once confirmed, the robot will restart the navigation module, and you'll see the app disappear from the apartment image, and the device status will change to "Maps not saved" or similar, and the device is now ready to build a new model of the room, usually just running a full cleaning.
Using the Roborock application for management
Owners of flagship models such as the Roborock S50, S6 or newer series often use a separate Roborock application, which provides advanced functionality for working with maps. The deletion procedure here is also intuitive, but has its own peculiarities in terminology.
In the control menu, go to the settings (three dots in the corner). Find the "Map settings" section. Unlike the basic application, there may be a feature for saving multiple cards if the model supports it. However, for a complete reset, we need the "Reset map" option.
Click on the appropriate button. The app will warn you that all the layout data, including rooms, floors and areas, will be deleted. Confirm action. In Roborock, the synchronization process may take a little longer due to more detailed routing algorithms.
- 📱 Open the Roborock app and select the device.
- ⚙️ Go to the settings menu via the three-point icon.
- 🗺️ Select the option “Card Settings” and click “Reset the card».
- ✅ Confirm the operation and wait for status update.
⚠️ Warning: If you use voice control through Google Assistant or Yandex Alice, after resetting the map, the room attachments to voice commands may fly off.
Preservation and restoration of maps
One of the key features of modern Xiaomi vacuum cleaners is the ability to save up to 4 different maps. This is ideal for multi-storey houses or apartments with complex layouts, where cleaning is divided into stages.
If you're just going to update the data, rather than delete it completely, you can use the editing function. You can combine rooms, divide them or rename them in editing mode, but if the map is corrupted by software, editing won't help, which is the complete reset that we talked about above.
Recovery of a remote card is impossible unless you back up in advance (not available in all regions and models). So if you accidentally delete the correct map, you'll have to start the robot completely cleaned up to build the new model from scratch. In the new navigation, try not to interfere with the robot and keep the doors open.
Comparison of Memory Cleaning Methods
There are several approaches to solving navigation problems, and the choice of the specific method depends on the severity of the situation. Below is a table comparing the different ways in which the robot maps.
| Method | Difficulty | Conservation of zones | Implementation time |
|---|---|---|---|
| Editing the map | Low. | Preserve. | 5-10 minutes |
| Reset via Mi Home | Medium | Removed | 10-15 minutes. |
| Reset via Roborock | Medium | Removed | 10-15 minutes. |
| Total reset (Reset) | Tall. | Removed | 30+ minute |
As you can see from the table, simple editing is the least time consuming, but it doesn't solve deep software errors. Full menu reset, sometimes confused with card deletion, affects all device settings, including Wi-Fi, and requires re-association to your account. Use this method only in extreme cases.
💡
For most users, the best solution is to remove the card through the application, since it does not require resetting the network settings of the device itself.
Building a new map: recommendations
Once you have successfully cleared the navigation memory, the robot is ready to create a new map. For best results, it is recommended to start the Quiet Cleanup mode or the standard full area mode. Do not use Spots or Local Cleanup mode at this time, as they do not give full coverage of the space.
During the first pass after reset, make sure all doors to the rooms are open, and there are no extra items (boxes, wires, toys) on the floor that the robot can mistake for obstacles or, worse, suck in.
If the robot has finished cleaning, but the map is not fully built or broken, don't panic. Often, just start the device for another cycle, and it will complement the missing areas, in the application you can manually combine the disparate areas or edit the boundaries of rooms after the process is completed.
- 🚪 Keep all interior doors open during construction.
- 🧹 Remove small objects and dangling curtains from the floor.
- 🔋 Make sure the robot doesn’t go to base in the middle of the mapping cycle.
- 📡 Provide a good Wi-Fi signal throughout the apartment area.
