Resetting Xiaomi robot vacuum cleaner with wet cleaning to factory settings: the full guide

Xiaomi’s wet-cleaning robots have become indispensable household tools, but sometimes they get lost due to software bugs, incorrect updates, or setting conflicts. In these cases, factory resets are the only way to restore stability to the device. However, the procedure has nuances: wrong actions can lead to loss of account binding, sensor failures, or even a water spray system failure.

In this article, we will discuss all official and alternative reset methods for Mi Robot Vacuum-Mop, Viomi V3, Dreame Bot and other Xiaomi wet cleaning robot vacuum cleaners. We will focus on critical errors that cannot be made when resetting water tank devices – they require additional steps to properly initialize the system.

When you need to reset the robot vacuum cleaner Xiaomi to factory settings

Resetting is not a universal solution to all problems, but it is necessary in the following cases:

• 🔄 The robot freezes during the booting stage or cyclically reboots (especially after firmware).
• 🚫 The device does not respond to commands from the Mi Home app or voice assistant.
• 💧 Wet cleaning system does not spray water or does so chaoticly despite cleaning nozzles.
• 🔌 The vacuum cleaner does not connect to Wi-Fi, even after multiple passwords are entered.
• 📱 Xiaomi account binding lost, and the robot requires re-authorization.

Before you start resetting, check out the simple solutions:

• ⚡ Reboot the robot (hold the power button for 10 seconds).
• 📶 Make sure the router supports 2.4GHz (many Xiaomi models don't work with 5GHz).
• 🔧 Update the Mi Home app to the latest version.

⚠️ Note: If Xiaomi’s wet cleaning robot was purchased in the secondary market, the reset may be blocked due to a link to the previous account.

Preparation for resetting: what to do in advance

Incorrect preparation can lead to loss of functionality after reset.

Disconnect the robot from the charging station

Make sure the water tank is empty.

Remove a napkin for wet cleaning

Check the battery charge (minimum 30%)

Prepare your Xiaomi account details (login/password)-->

Pay special attention to the wet cleaning system:

• 🚰 Be sure to drain water from the tank - spontaneous spraying can occur when discharged.
• 🧼 Wash the container and nozzles under running water to avoid blockages after rebooting.
• 🔋 If the robot supports automatic washing of a wipe (for example, DreameBot) L10 Ultra, remove it from the bay.

It is also recommended that:

• 📱 Take screenshots of current settings in the Mi Home app (cleaning schedule, exclusion zones, suction intensity).
• 🔄 If the robot is connected to Google Assistant or Alice, untie it in the settings of the voice assistant.

⚠️ Attention: On Viomi models V3 and DreameBot D9 After reset, the sensors may need to be recalibrated, and without it, the robot will misidentify the distance to the obstacles.

Ways to reset the robot vacuum cleaner Xiaomi to factory settings

There are three official reset methods, and one alternative (for power users), depending on the model and current state of the device.

Let us consider each method in detail.

Method 1: Resetting through a button on the body (universal method)

This is the most reliable method that works even if the robot is not connected to Wi-Fi, the instructions are suitable for 90% of Xiaomi models:

1. Turn off the robot vacuum cleaner (hold the power button for 3 seconds).
2. Press the buttons at the same time: 🔄 Food (or Home on some models) 📍 Spot Cleaning (Pinpoint Cleaning)

10-15 seconds

Release the buttons and the robot will start the reset process (can reboot several times).

On DreameBot models (e.g. D9 or L10), the combination may differ:

Hold the power button + suction boost button for 12 seconds.

💡

If the robot doesn’t respond to button retention, try plugging it into a charging station and repeating the procedure. Some models (like the Viomi V3) block the reset when the battery is low.

Method 2: Resetting through the Mi Home app

If the robot is connected to Wi-Fi and responds to commands, you can reset software:

1. Open the Mi Home app and select your robot vacuum cleaner.
2. Go to Settings → About the device → Reset settings.
3. Confirm the action (you may need to enter a password from your Xiaomi account).
4. Wait until the process is complete (the robot will restart).

On some models (DreameBot) the path may be different:

Settings → Additional → Restoration of factory settings

⚠️ Warning: Once reset via Mi Home, the robot will automatically unplug the account. QR-case-code.

Method 3: Reset via voice assistant (for advanced models)

If your robot vacuum cleaner is integrated with Alice, Google Assistant or Siri, you can try voice resetting:

• 🎤 Say: “Alice, reset the settings of the robot vacuum cleaner” (for devices with support for Yandex.Stations).
• 🔊 Or, “Hey Google, reset my vacuum cleaner” (for Google Home-linked models).

This method does not work on all devices and requires:

• 📶 Stable Internet connection.
• 🔄 Active synchronization of the robot with the cloud Xiaomi.

Method 4: Hardware reset (for experienced users)

If the robot is completely locked (it doesn’t turn on, doesn’t respond to buttons), you can try resetting through the contacts on the board, which requires disassembling the device and is only suitable for users with experience in repairing equipment.

Instructions for Mi Robot Vacuum-Mop:

1. Remove the top cover (unscrew 4 screws under the rubber legs).
2. Find the RESET or CLR contacts (usually signed) on the motherboard.
3. Close them with a metal object (such as tweezers) for 5-7 seconds.
4. Put the robot together and turn it on.

⚠️ Warning: Incorrectly closing contacts can disable the control board. LDS-laser (e.g., laser, L10 Ultra hardware reset requires additional calibration of the laser after assembly.

What to do after resetting: setting up a robot vacuum cleaner from scratch

After a successful reset, Xiaomi’s robot vacuum cleaner will return to the “out of the box” state.

Connect the robot to the charging station

Launch the Mi Home app and add the device

Complete the process of binding to the Xiaomi account

Set up Wi-Fi (2.4GHz only!)

Pour water and install a napkin for wet cleaning-->

Pay special attention to the setting of the wet cleaning system:

• 💧 On the Viomi models V3 and DreameBot L10 After discharge, you need to calibrate the water flow:

wipe-wash

It is also recommended that:

• 🗺️ Recreate a room map – old data may conflict with new settings.
• ⚙️ Update the firmware to the latest version (check the About Device section in Mi Home) → Update of the PO).
• 🔒 Set up parental controls if the robot is used in a home with children (to avoid accidental resets).

💡

Once reset, Xiaomi’s wet-cleaning robot can run the first 1-2 cleaning cycles unstable, which is normal: the device needs time to recalibrate the sensors and adapt to the room.

Common Resetting Mistakes and How to Avoid Them

Even experienced users make mistakes that lead to repeated failures or loss of functionality, the most common of which are:

Special attention is paid to robots with laser navigation (for example, DreameBot L10 Ultra or Viomi V3):

• 🔦 After reset, don’t move the robot manually until the first cleaning is complete – it knocks the calibration. LDS-scanner.
• 📏 If the robot begins to “lose” in space, start a re-scan of the room in the application.
