Xiaomi Mop Essential reset: a complete guide with photos and videos

Xiaomi Mop Essential Robot Cleaner (Model) STYJ02YM) — It's a popular automatic cleaning device, but even with it, there are sometimes problems: Wi-Fi connection errors, Mi Home app malfunctions, sensors malfunction, or loss of communication with the remote control. In 90% of cases, these problems are solved by a complete reset to the factory settings.

This article will help you do the reset correctly, without the risk of damaging your device or losing important data, and we'll look at all the ways you can do it, through the app, through physical buttons, even through hidden engineering commands, and then we'll look at when the reset is really necessary and when you can do it with simpler methods.

When do I need to reset Xiaomi Mop Essential?

Factory reset is a last resort, and before you start, make sure that your problem is not solved in other ways. Here are the exact signs that the device needs to be reset:

• 🔄 The robot does not connect to Wi-Fi, although the password is entered correctly (Error 52001 or 52002 in the application).
• 📱 The Mi Home app doesn’t see the vacuum cleaner, although it’s on and near the router.
• 🤖 The device moves chaoticly, ignores virtual walls, or doesn't return to base.
• ⚙️ After updating the firmware, glitches appeared: spontaneous inclusion, sensor errors.
• 🔋 The battery is discharged for 10-15 minutes, although I used to work 90+ minutes (provided the battery is not worn out).

If your situation doesn’t make it to this list, try restarting the vacuum cleaner first (hold the power button for 10 seconds) or reinstalling the Mi Home app.Reset erases all stored room maps, cleaning schedules and wet cleaning settings – it will be impossible to restore them after the procedure.

Preparation for resetting: what to do in advance

Before you drop the Xiaomi Mop Essential, follow these steps to avoid additional issues:

1. Save the maps. If the vacuum cleaner is still connected to the app, take screenshots of the maps in the Cleanup → Map section, and you'll have to recreate them after you dump them.
2. Check the battery power. The level must be at least lower. 30%. If the battery is discharged, connect the vacuum cleaner to the base on 20-30 minute.
3. Disconnect from other devices. Make sure the vacuum cleaner is not connected to Google Assistant, Alice or other voice assistants, and once reset, these connections will break.
4. Prepare the data to set up. Write down your Wi-Fi network name and password, which you'll need after the reset.

If you use Xiaomi Mop Essential with a proprietary self-cleaning base (STYJ02YM with an S at the end), disconnect it from the socket while you reset. In rare cases, the base may block the process.

⚠️ Note: If your vacuum cleaner was linked to a Xiaomi account in China (mainland China server), it will not be linked to an account on another server (for example, Russia or Europe) after the dump.

Method 1: Reset via Mi Home (recommended)

This is the safest method, as the app controls the process and minimizes the risk of errors, which is suitable if the vacuum cleaner is still connected to the Mi Home, but it is unstable.

Instructions:

1. Open the Mi Home app and go to the Devices tab.
2. Select your Xiaomi Mop Essential (if there are more devices, be guided by the name or photo).
3. Click on the three dots in the upper right corner → Device settings.
4. Scroll down and select Reset to factory settings.
5. Confirm the action by entering the password from the Xiaomi account (if required).
6. Wait until the process is complete (usually takes 1-2 minutes), the vacuum cleaner will restart and emit an audible signal.

Once reset, the device will appear in the Add Device as New List. Link it back, following the instructions in the app.

Method 2: Hardware reset through buttons on the body

If the vacuum cleaner doesn't connect to the app or you've forgotten your Xiaomi account, use physical buttons, which works even without the internet.

Step-by-step:

1. Turn off the vacuum cleaner by pressing and holding the power button for 3 seconds.
2. Press and hold two buttons at the same time: Food and Home (with the image of the house).
3. Hold them for 10-15 seconds until you hear a beep (beeping) and the indicator lights up.
4. Release the buttons. The vacuum cleaner will start the reset process (it will take about 1 minute).
5. After restarting, the device will be ready for a new setup.

If your Xiaomi Mop Essential model doesn’t have a Home button (for example, in early installments), use the Power + Cleanup combination (broom button).

💡

If the vacuum cleaner does not respond to the pressing of the buttons, check if they are blocked with a protective film (sometimes remains after unpacking).

⚠️ Warning: Do not interrupt the reset process, even if the indicator flashes longer than usual.Premature power outage can damage the firmware, and then you will need to connect to the PC through the PC to restore it. USB-C and specialty software.

Method 3: Reset via engineering menu (for power users)

This method is suitable if the standard methods did not work or you need to reset only individual settings (for example, networking).

Instructions:

1. Activate the voice assistant and say, “Open developer settings on Xiaomi Mop Essential.”
2. If voice input doesn’t work, try the command via the Mi Home app: developer_mode On (enter it in the Management section) → Teams).
3. After activating the developer mode, go to Settings → Additional → Engineering menu.
4. Select Factory Reset and confirm the action.

In the engineering menu you can also reset:

• 📡 Wi-Fi (Network Reset) settings – if only the connection issues.
• 🗺️ Map Reset – if you need to clear the saved routes.
• ⚙️ Sensor Calibration – if the robot is not able to correctly detect obstacles.

💡

The engineering menu allows you to selectively reset without affecting all settings. Use it if you're sure of the cause of the malfunction.

What to do after resetting: setting up from scratch

After a successful reset, Xiaomi Mop Essential will be “clean” — as after buying. To get it back to work, follow these steps:

1. Connect to the app: Open Mi Home → Add the device → Choose a Robot vacuum cleaner. Follow the instructions: turn on the vacuum cleaner, wait for the beep, and connect to the robot's temporary Wi-Fi network (Xiaomi_Vacuum_XXXX). Select your home Wi-Fi network and enter your password.
2. Set up the basic parameters: 📏 Set the floor type (laminate, tiles, carpet) in the section Cleaning settings. 💧 Set up Wet Cleaning Intensity (Mop Essential has 3 levels available). ⏰ Create a cleaning schedule if you need to turn on automatically.
3. Update your firmware: Go to Settings → Update your software and install the latest version, which will fix any bugs and improve sensor performance.

If after the discharge the vacuum cleaner began to work worse (for example, it builds a route worse or discharges faster), check:

• 🔋 Battery state in the Device state (if capacity) < 80%, it's time to change the battery).
• 🧹 Clean sensors and brushes (contamination can affect navigation accuracy).
• 📶 Wi-Fi signal at the cleaning site (weak signal causes delays in work).

Common Resetting Mistakes and How to Avoid Them

Even when following instructions, users often make mistakes that lead to new problems, and here are the most common ones and ways to prevent them:

If after resetting Xiaomi Mop Essential produces error 10 (collision sensor problem), calibrate:

1. Place the vacuum cleaner on a flat surface.
2. Press the power button for 5 seconds until you hear a double signal.
3. Release the button and wait for the process to be completed (the robot will scroll the wheels and make a long sound).

💡

If you have problems after reset, check the server region in the Mi Home application. Devices for China (Mainland China) may not work correctly with servers in Russia or Europe.
