Modern robotic assistants from Xiaomi and the Mijia ecosystem are famous for their autonomy and smart navigation functionality, but even the most advanced algorithms sometimes fail, requiring user intervention. The situation when a device stops responding to commands, loses contact with the router or begins to build an incorrect map of the room is familiar to many owners of smart equipment. In such cases, the only right solution is a complete reset that returns the gadget to its original state.
The reset procedure may be required not only when critical software errors occur, but also when you change your residence, buy a new router, or transfer the device to another user. It is important to understand that there are different levels of reset, from simply breaking the Wi-Fi connection to deep cleaning of the internal memory of the card. The specific method depends on your end goal and the robot model, so before you start the action, you need to clearly determine what exactly you want to get.
In this guide, we will discuss in detail all available ways to reinitialize the system, consider the nuances of working with the Mi Home application and answer frequent questions that arise during operation. Proper execution of the sequence of actions ensures the restoration of the operability of your robot vacuum cleaner without the risk of damage to the hardware.
When a complete reset of the navigation system is required
The first sign that your robot needs to reset its logic is chaotic behavior during cleaning, and it can start building a map from scratch every time it’s installed, ignite previously installed virtual walls, or get stuck in places it’s previously been driving freely. This indicates the accumulation of logical errors in the module. SLAM-Navigation or damage to configuration files.
Another common reason is that you can't connect to a new wireless network: If you change your ISP, your Wi-Fi password, or just move to another home, your old network profile may conflict with an attempt to log in under new conditions, in which case the standard application reconnection procedure often fails, requiring more radical cleanup measures.
Also, resets are required when you transfer your device to a new owner or when you sell it, and the robot's memory stores your account, your cleaning schedule, and most importantly, your home map, and to ensure privacy and allow the new user to customize the gadget, you need to delete all personalized data.
Preparation of equipment and software
Before you start manipulating the system files of the device, you need to make sure that its power supply is stable. Interrupting the reset process due to battery discharge can damage the file system, after which the robot will stop booting. Set the device on the charging base and make sure that the charge indicator is green or flashing, signaling full or sufficient energy levels.
The second important step is to prepare your smartphone. Make sure that the latest version of the Mi Home app (or Xiaomi Home) is installed on your mobile device, as older versions may lack the necessary controls or there may be bugs that interfere with proper operation. Also check that your phone is connected to the same Wi-Fi network to which the vacuum cleaner was previously tied if you plan to perform a software reset.
☑️ Checklist before reset
After resetting, some models can begin calibrating the sensors or running tests, so make sure there are no obstacles, wires or small objects around the base and the device that can get into the brush during a test run.
Hardware reset buttons on the body
The most reliable and versatile way to get the device back to factory settings is to use physical control buttons, which works even when the robot is not connected to the Internet or the application is not responding. Most Xiaomi and Roborock models use a combination of buttons to do this. Usually you need to simultaneously press the on button and the return button to the base (or the local clean button) for 5-10 seconds.
When holding the buttons, the device will give an audible signal or a voice message confirming the start of the reset process. For example, the popular Roborock S5 model reports with the phrase "Resetting Wi-Fi", which means resetting only network settings. For a complete reset, including a card, it sometimes requires holding the buttons longer - up to 15-20 seconds until the robot says "Resetting settings" or a similar phrase.
⚠️ Warning: Do not release the buttons immediately after the first beep. Often the first signal means only entering Wi-Fi pairing mode, and the second, longer beep or voice message confirms that the reset of all settings confirms the reset of all settings.
Once the command is successfully executed, the robot will automatically restart, and the indicators can start flashing orange, which signals a standby mode of connection, which means that the device is "clean" and ready for a new setup as if it had just left the assembly line.
What to do if the buttons do not respond?
Delete the device through the Mi Home app
The software method of removing the device from the Xiaomi ecosystem is the most correct one from the smart home logic: When you remove the device from the application, a command is sent to the server about the breakup of the connection, and the authorization token is canceled, which is especially important if you plan to sell the gadget or transfer it to another person so that he can link it to his acca-unt.
To do this, open the Mi Home app, find your robot vacuum cleaner card and click on it to go to the control menu. The top right corner of the screen usually has a three-dot or gear icon that opens additional settings. At the bottom of the menu that opens, you need to find the Remove device button and confirm the action.
Once confirmed, the device will disappear from your gadgets list and its status in the app will change to "Offline." However, it is worth remembering that this method often resets only the account and Wi-Fi binding, but the room map can remain in the internal memory of the robot itself.
| Resetting method | What's cleansed | Internet is required | Difficulty |
|---|---|---|---|
| Buttons on the case | Wi-Fi, Map, Schedule | No. | Low. |
| Removal at Mi Home | Account binding | Yes. | Low. |
| Reset via menu | Only Wi-Fi. | No. | Medium |
| Button combinations | Full reset (depending on model) | No. | Tall. |
Cleaning the room map and restoring navigation
One of the most common reasons for resorting to resetting is map damage, where laser rangefinder (LDS) or visual navigation (VSLAM) robots build complex mathematical models of the room that can eventually become "junk" - false obstacles or breaks in the contours of walls, in which case a full reset allows the robot to scan the room again and build the optimal route.
To clean the map without completely resetting all settings, some advanced models have a separate feature. In the map settings menu in the Mi Home or Roborock app, you can find the option "Reset the card" or "Delete the card", and then the robot will ask to start a full cleaning or map construction mode, during which it re-examines all available areas.
💡
Save the map before reset: If you have a complex layout with many rooms, take a screenshot or photo of the current map in the application before resetting the card. This will help you navigate faster when setting up virtual walls after restoration.
It is important to note that once the map is reset, all previously installed virtual walls, no-go zones and room cleaning schedules will be lost, and you will have to re-enter the zoning and restriction settings, which may take some time, but this is necessary for the navigation system to work properly.
⚠️ Warning: If after resetting the card, the robot continues to build an incorrect image (splits rooms, sees no obstacles), check the protective glass of the laser rangefinder. LDS 80% of navigation problems, not software failure.
Solving Connection Problems After Reset
Once you have reset, the robot goes into standby mode, at which point users often have difficulty re-authorizing. Make sure your smartphone is connected to a 2.4GHz Wi-Fi network. Xiaomi’s vacuum cleaners have little or no support for 5GHz networks, and trying to connect to them will result in a timeout error.
During the setup process, the app will ask you to enter your Wi-Fi password. Be careful when you type in: case sensitivity and the presence of unnecessary spaces can cause failure. If the robot is not online, try to bring the smartphone as close to the base as possible and repeat the search procedure for the device. Sometimes it helps to temporarily disconnect mobile Internet (3G/4G) on the smartphone during the setup so that the device does not try to use alternative communication channels.
If the Wi-Fi indicator on the robot flashes, but the device does not appear in the list available for addition in the application, try changing the region in the Mi Home app settings. Some models designed for the Chinese market (CN Version) require selecting the "China" region, while the global versions work with the region of your country or "Europe".
💡
The right region in the Mi Home app is critical for the device to run smoothly and receive firmware updates.
