How to reset the robot vacuum cleaner Xiaomi to factory settings: 4 proven ways

Xiaomi's robot vacuum cleaners are smart devices that accumulate errors over time, like losing Wi-Fi connection, building incorrect maps of space, or ignoring commands. 80 percent of the time, a full factory reset solves these problems. But how do you do it right so you don't turn a vacuum cleaner into a brick?

In this article, we will take a full look at all the official and hidden reset methods for Mi Robot Vacuum, Viomi, Dreame and other brands. We will analyze the reset through physical buttons, the mobile app, and what to do if the vacuum cleaner does not respond to commands. We will separately focus on the nuances for devices with and without LiDAR – this is critical for correct operation after reset.

Why you may need to reset your settings

Factory reset is not a panacea, but an effective way to fix software failures.-5 Reasons when the procedure is necessary:

• 🔄 The vacuum cleaner forgets the map of the room after each turn on or builds it with errors
• 📶 Continuously losing Wi-Fi connection despite stable router
• ⚠️ Error 10, Error 18, and Sensor Fault
• 🔒 The device is tied to an old Mi Account, and the previous owner did not untie it
• 🛠️ After a failed firmware update, the vacuum cleaner is not working correctly

It is important to understand that a reset deletes all user data, including:

• 🗺️ Stored maps of premises and cleaning areas
• 🔑 Schedule and mode settings
• 📱 Linking to Mi Account Home/Mi Robot App
• 🔊 Individual parameters of suction and wet cleaning

⚠️ Note: If the vacuum cleaner gives an Error 5 (fan problem) or Error 9 (brush jamming), resetting won’t help – physical repairs are required.

Method 1: Reset via buttons on the body (for all models)

It's a universal method that works even if the vacuum cleaner isn't connected to Wi-Fi or an app, and it's suitable for most Xiaomi Mi Robot, Viomi V2/V3, Dreame D9/Z10 and others, and it's important to get the buttons right.

Instructions:

1. Turn off the vacuum cleaner with a long press on the power button (usually 3-5 seconds).
2. Press the buttons at the same time: 🔘 Power (Power) 🏠 Home or Spot Cleaning (if there is no Home button)

10-15 seconds

For models with touch buttons (for example, Mi Robot Vacuum-Mop 2 Pro):

1. Press and hold the power button for 5 seconds to turn off.


2. Press the "Food" and "Home" buttons for 10 seconds at the same time.




3. After vibration release - reset started.

⚠️ Note: On the Xiaomi Mi Robot Vacuum-Turbo (2023) button reset is blocked if the device is tied to an account!

Method 2: Reset via Mi Home/Mi Robot App

If the vacuum cleaner is connected to Wi-Fi and displayed in the app, it is safer – it saves some settings (for example, cleaning history), suitable for models that support firmware 3.5.8 and later.

The following steps are taken for Mi Home:

1. Open the app and select your vacuum cleaner.
2. Go to Settings → About the device → Reset settings.
3. Confirm the action by entering a password from the Mi Account.
4. Wait until the finish (the vacuum cleaner will restart and emit an audible signal).

💡

If the vacuum cleaner does not appear in the application after reset, remove it from the list of devices and add it again through “Add device” → “Vacuum cleaner”.

Method 3: Reset via voice assistant (for models with Alice/Google Assistant)

A little-known method that works for voice-enabled vacuum cleaners (such as the Mi Robot Vacuum-Mop 2 Lite or Dreame D10 Plus) is suitable if physical buttons do not respond.

Instructions:

1. Activate the voice assistant (OK, Google, or Alice).
2. Tell the command: "Reset the vacuum cleaner settings [device name]."
3. Confirm the action by voice or through a notification in the app.

Limitations of the method:

• 🚫 It only works if the vacuum cleaner is connected to Wi-Fi and account
• 🚫 Not supported on models older than 2020
• 🚫 Requires pre-setting of voice control

Method 4: Emergency discharge for "blocked" vacuum cleaners

If the vacuum cleaner doesn't turn on, doesn't respond to buttons, or gives out an Error 24 (a critical system error), you'll need a hardware reset, which is risky, because if you do it wrong, you can damage the control board.

You'll need:

• 🔧 Screwdriver. T5 or T6 (disassemble)
• 🔌 Charged battery (minimum 50%)
• 📌 paperclip or thin wire for closing contacts

Step-by-step:

1. Disconnect the vacuum cleaner from the charging station.
2. Turn it over and unscrew the 4 screws on the bottom cover (usually under rubber legs).
3. Carefully remove the cover so as not to damage the sensor wires.
4. Find the Reset button on the control board (usually red or black, signed RST).
5. Close the contacts of the button with a clip for 5-7 seconds.
6. Collect the vacuum cleaner in reverse order.

⚠️ Note: On Xiaomi Mi Robot Vacuum 2 models, the Reset button is hidden under a thermal paste - do not try to find it without experience.

Signs of a successful emergency discharge:

• 🔄 The vacuum cleaner will emit a long squeak when turned on
• 🔦 LED-The indicator will flash red-green
• 📱 In the appendix, the device will appear as "New"

💡

If the vacuum cleaner is warranty, it is better to contact the Xiaomi service center, so as not to lose warranty service.

What to do after resetting: setting up from scratch

After the vacuum is discharged, the vacuum cleaner will return to the "out of the box" state.

1. Connect to Wi-Fi: 📶 Use a 2.4 GHz network (5 GHz not supported) 🔑 The network password should not contain Cyrillic or special characters
2. Update firmware: 🔄 In the application will appear notification of the update – install it ⚡ The process will take 5-15 minutes, do not interrupt the meal

Create a new map of the premises

• 🗺️ Start cleaning in "Full cleaning" mode"
• 🚪 Close all doors so that the vacuum cleaner is not lost»

Tips for quick setup:

• 📱 Keep a backup of the card in the app (if supported)
• 🔒 Set up two-factor authentication in your Mi Account to avoid device theft
• 📅 Create a cleaning schedule for days when you are not home.

Frequent Resetting Mistakes and How to Avoid Them

Even a simple reset procedure can go wrong, if you don't take into account the nuances.-5 User errors and their consequences:

1. Interrupting the reset process: If you release the buttons ahead of time or turn off the vacuum cleaner during a reset through the app, the device can hang on the Xiaomi logo.Solution: Repeat the reset or use the emergency method.
2. Resetting low battery charge: If the charge is less than 30%, the vacuum cleaner may shut down during the procedure and require repair.Always check the charge level before resetting.
3. Using the wrong buttons: For example, on the Viomi V3, some users try to reset settings via Power + Turbo, but this results in activation of the diagnostic mode, not reset.
4. Incorrect sequence: First you turn off the vacuum cleaner, then hold the buttons, and if you do this on the device on, the reset will not start.
5. Ignoring updates after reset: Outdated firmware can cause repeated crashes. After reset, be sure to update the software through the application.

⚠️ Note: Dreame models with firmware 5.4.0 and higher require re-assignment to the account within 24 hours, otherwise the device will be locked.
