Xiaomi’s robot vacuum cleaners may eventually become incorrect, losing communication with the app, ignoring commands, or taking chaotic routes, and 80 percent of the time, these problems are solved by completely resetting to factory settings, but the procedure differs depending on the device model and firmware version.
In this article, we will discuss all the current methods of resetting for Xiaomi, Viomi and Dreame robot vacuum cleaners (including the popular Mi Robot Vacuum, S10, X10 series, etc.), you will learn how to correctly reset through an application, physical buttons or service menu, and what to do if the device does not respond to standard methods.
Important: Reset removes all stored room maps, cleaning schedules, and personal settings, and backing up data in the Mi Home app won't restore those settings -- they'll have to be reconfigured.
1. When you need to reset the robot vacuum cleaner settings
Factory reset is the last resort of system failures, and these are typical situations where the procedure is justified:
- 🔄 The robot doesn’t connect to Wi-Fi or permanently loses communication with the app, despite the correct password and stable Internet connection.
- 🗺️ The device does not save a map of the room, although it used to work normally, or creates chaotic routes instead of planned ones.
- ⚙️ After the firmware update, there were lags, freezes or errors like Error 12 (collision sensor error).
- 🔒 The robot is tied to an old Mi Home account, and the previous owner can not remotely untie it.
- 🛠️ The device does not respond to commands from the remote or through the voice assistant (Alice, Google Assistant).
If the problem is hardware-based (e.g., the robot is not charging or making uncharacteristic noises while driving), resetting is unlikely to help, requiring a diagnostic at a service center.
⚠️ Note: Xiaomi Mi Robot Vacuum-Mop 2 Lite and Viomi V3 push-button RESET This can lead to blocking the wet cleaning function. After the procedure, check the mop module settings in the application.
2. Method 1: Reset via the Mi Home app
The safest method is to use the official Mi Home app (or Xiaomi Home for newer versions), which is suitable for all models that support Wi-Fi connectivity, including the Mi Robot Vacuum-Mop P, Dreame D9 and Viomi SE.
Instructions:
- Open the Mi Home app and go to the Devices tab.
- Choose your robot vacuum cleaner from the list.
- Press three points (⋮) in the upper right corner and select Settings.
- Scroll down and find Reset Settings (or Delete Device on older versions of the app).
- Confirm the action. The robot will sound and start the reset process (1-3 minutes).
Once completed, the robot will automatically reboot, and you will need to re-link it to your account and adjust the cleaning options.

Stable Wi-Fi connection
Closed all applications using Bluetooth (may interfere with communication)-->
⚠️ Note: Some of the firmware (Mi Robot Vacuum) 1S version 3.5.8_004026) The reset may not be available. In this case, use hardware reset (see next section).
Method 2: Hardware reset (buttons on the body)
If the robot is not connected to the app or is stuck, use physical buttons. The method works on all Xiaomi models, but the location of the buttons may vary.
Common algorithm:
- Turn off the robot with a long press on the power button (usually) ⏻ or ON/OFF).
- Find the RESET button (can be hidden under a plug or combined with the HOME button).
- Press the RESET for 5-10 seconds until you hear an audible signal (on some models, an orange indicator will light up).
- Release the button and wait for the reboot (the robot will say "Reset successful" in English or will play a tune).
For specific models, there are nuances:
| Model | Location of the RESET button | Retention time | Sign of successful discharge |
|---|---|---|---|
| Mi Robot Vacuum 1/1S | Under the lid next to the power button | 8-10 sec. | Voice message in English |
| Viomi V2/V3 | Side, under a rubber cap | 5 seconds | Blinking white and red LED |
| Dreame D9/F9 | Inside the dust collector compartment | 10 seconds. | Sound signal + reset |
| Mi Robot Vacuum-Mop 2 Pro | HOME button (hold with power) | 12 seconds | Voice message in Chinese |
If the robot doesn't turn on after reset, plug it into the charging base for 30 minutes, and it may have run out of battery during the procedure.

Method 3: Reset via service menu (for advanced users)
This method is suitable for models with debugging mode, such as Mi Robot Vacuum 2 or Viomi V6. It allows you to reset the settings without losing some calibration data (it is useful if the robot after reset goes crooked).
Instructions:
- Turn on the robot and wait until it gives a welcome signal.
- Press and hold the HOME + SPOT CLEAN buttons at the same time for 3 seconds.
- Release the buttons when the blue indicator flashes (this means logging into the service menu).
- Press HOME once and the robot will say "Factory reset".
- Confirm the reset with another tap of HOME.
After that, the device will reboot. This method does not reset the calibration of the sensors, which can be critical for robots with LiDAR (laser scanner), for example, Mi Robot Vacuum-Mop P.
⚠️ Warning: Continuously holding buttons for more than 15 seconds in the service menu can cause the robot to reset regional settings, as a result, switch to the Chinese language of voice prompts, and some functions (for example, integration with Yandex Alice) will stop working.
💡
If the robot speaks Chinese after reset, you can return Russian through the Mi Home app: go to the device settings → Voice prompts → select Russian. On some models (Viomi V3), this will require changing the account region to Russia in the profile.
5. Features of resetting for robots with LiDAR and cameras
Models with laser scanners (Mi Robot Vacuum-Mop 2 Pro, DreameBot X30) and cameras (Viomi V7) require additional calibration after reset. If you skip this step, the robot will inaccurately build a map or collide with furniture.
What to do after the discharge:
- 📏 Place the robot on a flat surface (floor without carpets) at a distance of at least 1 meter from the walls.
- 🔄 Turn it on and wait for it to say "calibrating sensors." Don't interrupt the process!
- 🗺️ Run the first cleaning in Full Cleaning (not point) mode so that the robot creates a new map.
- 🔧 In the Mi Home app, check your LiDAR settings: go to Settings → Sensors. → Calibrate LiDAR and follow the instructions on the screen.
On cameras (Viomi V7, DreameBot Z10 Pro) after reset, you may need to re-link to your cloud account to work with the object recognition function, without which the robot will not distinguish shoes from obstacles.
💡
For robots with LiDAR (Mi Robot Vacuum-Mop 2 Pro, Dreame D10 Plus) after reset, be sure to update the firmware to the latest version. Older versions of the software (below 4.6.1) can misinterpret the scanner data, which will cause the robot to "lose" in spacious rooms.
6. Frequent errors in resetting and how to avoid them
An improperly executed reset can make problems worse, and here are the typical user errors:
- ⚡ Interrupting the process: if the robot is turned off during reset (for example, due to battery discharge), this can damage the firmware. USB-OTG service-centre.
- 🌍 Incorrect region: If the robot was bought in China and you dropped it through your Mi Home account, some features (such as voice prompts in Russian) may disappear.
- 🔌 Reset without decoupling from your old account: if the robot is tied to another user, a new reset will not help.First request removal of the device through Xiaomi support (need to use the new reset). IMEI robot).
- 📱 Using informal firmware: on robots with custom software (for example, Valetudo), resetting through standard methods can lead to "bricking". SSH.
If the robot does not connect to Wi-Fi after reset, try:
- Reboot the router.
- Use 2.4 GHz network (Xiaomi robots do not support 5 GHz).
- Change the encryption type from WPA3 to WPA2-PSK.
- Manually specify DNS 8.8.8.8 in the router settings.
7 What to do if the discharge did not help
If problems persist after reset, check the following:
- Battery status: If the robot is running less than 20 minutes on the battery, it needs to be replaced. Use the Mi Home app to check.
- Sensor cleanliness: wipe LiDAR (laser eye), optical sensors and charging station contacts with an alcohol napkin.
- Firmware: Update the software through the app. On Dreame models, this may require a USB-C connection to your computer.
- Mechanical damage: inspect the wheels, brushes and bumper for cracks or foreign objects.
If the robot doesn’t turn on at all, try:
- Connect it to the charging base for 12 hours (possibly a deep discharge).
- Press and hold the power button for 20 seconds (sometimes it works on models with stuck firmware).
- Call the battery contacts with the tester (voltage should be 14.4-16.8 V).
For Xiaomi robots older than 3 years, the problem is the wear of the engines. If the device hums after reset, but does not move, it is likely that the wheel motors or the main suction engine will need to be replaced.
