Xiaomi’s modern robot vacuum cleaners are complex AI-driven devices that can sometimes fail to be fixed by a normal reboot, and the only solution is a complete reset.
Factory resetting helps to eliminate software bugs, clear the navigation cache, and reconnect the gadget to a new network, a process often referred to as "hard reset," and it returns the device to its original state as if you just took it out of the box.
In this guide, we will discuss in detail all known ways to return to factory parameters for different series of robots, you will learn when to apply a hard reset, and when a conventional reboot is enough, and how to properly prepare the equipment for this procedure.
When a complete system reset is required
You don't have to take drastic measures every time you sneeze, but there are situations where a complete reset is the only way to resuscitate a smart assistant, and if the robot stops responding to commands or loses communication with the server, that's the first call to action.
Often problems arise after updating the firmware or changing the configuration of the home Wi-Fi network. The device can "remember" the old data of the router and stubbornly refuse to connect to the new one, in which case, cleaning the memory of old network profiles is simply necessary.
⚠️ Warning: Before starting the procedure, make sure that the battery is at least 40% charged. interruption of the reset process due to battery discharge can cause damage to the file system.
Resets are also required when transferring the device to a new owner or when selling, ensuring that your personal data, including apartment maps and cleaning history, is completely deleted. For models with a laser rangefinder (LDS), this also helps the recalibrate navigation system if it starts building wrong routes.
Preparation for the recovery procedure
Before you press the cherished button, you need to do a number of preparatory steps, which will protect your data and ensure the stability of the process, first of all, open the Mi Home app or Xiaomi Home on your smartphone.
You need to untie the device from your current account. This is a critical step, because otherwise the new owner will not be able to add a vacuum cleaner to himself, and you may encounter a binding conflict when reconfigured. Find the device in the list, go to the settings (three dots in the corner), and select "Delete the device."
When removed from the application, it is recommended to turn off the robot itself. To do this, press the power button or use a button combination specific to your model. Make sure that the indicators are turned off, and only then start mechanically acting on the control buttons.

Take a picture of the current cleaning schedule and no-go settings before resetting, and once you've recovered, you'll have to manually recreate them, and the photo will speed up the process.
Resetting methods for different Xiaomi models
The company's range is large, and the reset methods may vary depending on the series. For most modern models, such as the Roborock S50/S55, Xiaomi Vacuum Mop and Viomi, the procedure is standardized, but has its own nuances.
The classic method involves simultaneously pressing two buttons, usually home and power. In some models, such as the Mijia 1C or G1 series, you may need to press the power button and the local clean button, holding them for a long time, about 10-15 seconds, until the characteristic beep.
For models with voice control or touch panels, the algorithm may be different, sometimes you need to remove the top cover with a water tank to get to the hidden Reset button. The table below shows the combinations for popular series:
| Device series | Button combination | Duration of retention | Sound signal |
|---|---|---|---|
| Xiaomi Vacuum 1 / 1S | Home + Food | 3-5 seconds | Short squeak |
| Roborock S5 / S50 | Home + Food | 10 seconds. | Voice confirmation |
| Mijia 1C / G1 | Food + Local | 5-7 seconds | Long horn |
| Viomi V2 / V3 | Two buttons next | 10 seconds. | Melody. |
If standard combinations don't work, check the specific model instructions. Some devices require a paper clip to press a recessed Reset button on the side or under the lid. The key is to keep the buttons on immediately after the indicators are turned on, wait for color changes or audible confirmation.
☑️ Checklist of successful reset
Reset via the Mi Home app
It doesn't always require physical interaction with the buttons. Software resets can be done directly through the smartphone interface if the device still maintains communication with the router, a method that is more gentle and allows you to save some user data if it is provided by firmware.
Open the app and go to the vacuum control menu. Click on the three dots in the upper right corner to enter the additional settings. In the list of options, find "General settings" or "Device settings."
Inside the menu, you should look for the option "Reset" or "Factory Reset." The system will request confirmation of the action, warning of the consequences. Once you press the "OK" button, the device will reboot and return to factory settings. This method is ideal if the buttons on the case are already worn out or crash.
⚠️ Note: Software reset does not always clear the room map. Complete cleaning of the map often requires a physical reset with buttons, described in the previous section.
In some versions of MIUI Home, the reset option may be hidden in the About Device section, which may require multiple clicks on the software version, a hidden menu from engineers to perform deep cleaning.
Setting up Wi-Fi after recovery
After a successful reset, the robot vacuum cleaner goes into pairing mode, the Wi-Fi indicator starts flashing, signaling readiness for connection, and now it's time to re-introduce the device into the smart home ecosystem.
In the app, click "+" to add a new device. The system will automatically find a vacuum cleaner on the local network. 4 GHz. If your router broadcasts 2.4 and 5 GHz networks under the same name, it can be difficult.
In this case, temporarily split the networks in the router settings or turn off 5 GHz during the setup. Enter the Wi-Fi password, and the robot will begin the connection process. After successful synchronization, the indicator will stop flashing and light up with a straight light.
What if the robot can’t see the 2.4GHz network?
Problems with map and navigation
One of the main reasons for the reset is the loss of a room map. The LDS laser module or visual camera can accumulate errors, causing the robot to "lose" in its own apartment, and after reset, the navigation memory is cleared, and the device builds the map again.
When you first start after you reset, you start the robot to clean it up completely, and don't interrupt it, even if it seems chaotic, while the mapping algorithm scans the room, identifying walls, furniture and obstacles, and interrupting this process can lead to fragmentation of the map.
If the map is still incorrectly displayed after resetting and reconfiguring, check the cleanness of the laser rangefinder. Dust on the protective glass of the LDS turret is a common cause of navigational failures. Gently wipe the sensor with dry soft cloth.
💡
A complete reset and re-building of a map from scratch often solves 90% of the problems with the robot’s chaotic movement and refusal to return to base.
