How to reset the card in the robot vacuum cleaner Xiaomi Vacuum Mop: all working ways

Xiaomi vacuum cleaners with mapping function – such as Mi Robot Vacuum-Mop 2 Pro, Dreame D9 viomi V3 — They may eventually start to confuse the plan of the apartment, lose rooms, build routes incorrectly, or even stop saving a map, most often solved by resetting the map, a procedure that deletes the stored data about the room and forces the robot to retrain from scratch.

But how do you do that? Depending on the model and the firmware version, the ways are different: somewhere you just press one button in the application, and somewhere you have to do a hard reset through the physical keys on the body. In this article, we will examine all the current methods, from standard to hidden, and also explain why the robot can “forget” the map and how to avoid this.

⚠️ Important: Before resetting the card, make sure that the robot is fully charged (at least 80.

1.When to reset the map on a robot vacuum cleaner

Don't be in a hurry to reset the card the first time you fail, and here are some objective signs that the procedure is really necessary:

• 🗺️ The robot does not save the map after cleaning (the app displays an empty field or chaotic lines).
• 🔄 The device confuses the room: for example, goes to wash the kitchen, and washes the corridor.
• 🚧 Ghost walls appear as robot bypasses non-existent obstacles.
• ⚠️ The application is called Map Error or Navigation Failed.
• 🔄 After updating the firmware, the map began to be displayed incorrectly.

If the robot is just slowly building a map or sometimes gets lost, try rebooting it first (hold the power button for 10 seconds). 70% of the time, this solves the problem without completely resetting.

2. Method 1: Reset the card through the Mi app Home/Dreame

The easiest and safest method is to use the official app. The instructions are suitable for most Xiaomi, Dreame and Viomi models (for example, Mi Robot Vacuum-Mop 2 Lite, Dreame). D10 Plus).

Step-by-step:

1. Open the Mi Home app (or Dreame for the respective models).
2. Select your robot vacuum cleaner from the list of devices.
3. Go to the Map section (or Map in English).
4. Press three points (⋮) top-right.
5. Select Clear the map (or Reset Map).
6. Confirm the action – the card will be removed irreversibly.

Once reset, the robot will start a new cleaning operation with complete retraining, and the first cycle can take 20 to 30 percent longer than usual, which is normal.

Make sure the robot is charged (>50%)

Connect to the same Wi-Fi network as the robot

Close all doors to the rooms (for accurate mapping)

Remove small objects (wires, toys) from the floor

-->

⚠️ Note: if the application does not have a Clear Map button, then your model does not support software reset. In this case, use the hardware method (see the next section).

3. Method 2: Hardware reset through buttons on the body

Some models (e.g. Xiaomi Mi Robot Vacuum-Mop) G1 or older versions of Viomi) require a physical reset via a button combination, which will also help if the robot is not connected to the application or is stuck.

Instructions for most models:

1. Turn off the robot with a long press on the power button (3-5 seconds).
2. Hold the buttons at the same time: Power + Home (for models with the Home button), Food + Spot Cleaning for models without Home button).

10-15 seconds

Release the buttons and the robot will reboot and reset the map.

⚠️ Attention: on models with LDS-lidar (e.g. Dreame) Z10 Pro) hardware reset can also reset suction settings and cleaning schedule. After the procedure, check the settings in the application!

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

Some newer models (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Ultra) support control via voice assistants, which allows you to reset the map without an app using a command.

How it works:

1. Activate the voice assistant (Alice, Google Assistant, or Siri).
2. Say the command: For Alice: "Clear the map on a robot vacuum cleaner"; for Google: "Hey Google, reset map on my vacuum cleaner"; for Siri: "Hey Siri, clear the map on Xiaomi robot."

Confirm the action in the application (if necessary).

⚠️ Limitations of method:

• ❌ It only works on models with support for Yandex IoT or Google Home.
• ❌ You may need to link the robot to your assistant account.
• ❌ Not all firmware supports voice reset (check the robot settings section Voice control).

💡

If the voice reset didn’t work, try first saying the command “Reboot the robot vacuum cleaner” and then repeating the request to clean the map.

5. Method 4: Complete reset to factory settings (extreme case)

If the robot has completely stopped saving the card, hangs while cleaning or gives an error LDS error, may require a complete reset, this procedure deletes all information, including:

• 🗺️ Save maps;
• ⚙️ Suction and wet cleaning settings;
• 📅 Cleaning schedule;
• 🔒 Wi-Fi connection data.

How to make a hard reset:

1. Turn off the robot.
2. Hold the power button for 20-30 seconds until you hear a long beep.
3. On models with a display will appear an inscription RESET or FACTORY.
4. After restarting, set up the robot again through the application.

⚠️ Warning: Once completely reset, the robot will forget all the cleaning areas and virtual walls, and you'll have to reconfigure them! To avoid this, take a picture of the map screen in the app before resetting.

💡

A full reset is the last option. Try a software reset or a robot reboot first.

6 Why the robot is constantly resetting the map itself: causes and solutions

If your Xiaomi Vacuum Mop regularly loses the card without your intervention, the problem may be one of the following:

🔍 Hidden problem: If the robot builds the map normally but doesn't save it after turning it off, check the cloud-saving settings in the app. In some firmware, this option is disabled by default!

How to enable card saving in the cloud:

1. In Mi Home, go to Robot Settings → Map. → Cloud-based conservation.
2. Activate the switch.
3. Confirm the binding to the Xiaomi account.

7. Frequent errors when resetting the card and how to avoid them

Even a simple procedure can go wrong, except for the nuances, and here are the typical user errors and their consequences:

• 🔋 Resetting the card at low charge → The robot does not have time to retrain and “forgets” part of the room. ⚠️ Warning: If the battery runs out during the first cleaning cycle after reset, the card may not be complete%!
• 📶 Resetting without Wi-Fi connection → The card is not synchronized with the application. ⚠️ Warning: If the robot is not connected to the network, the new card will be stored only in its memory and disappear after turning off.
• 🚪 Change of planning during retraining → The robot remembers temporary obstacles (such as an open door) as permanent obstacles.
• 🔄 Interrupting the first cleaning cycle → The map is built fragmentary, with gaps.

💡

If the robot doesn't build a map after reset, try to slow down the cleaning speed in the settings. At high speed, the lidar may not be able to scan the room.

8. Alternative solutions: what to do if the discharge did not help

If the robot is still not working properly after resetting the card, the problem may be deeper.

• 🔄 Roll back the firmware (if the crashes started after the update). In Mi Home, go to Settings → About the device → Update and select the previous version (if available).
• 🛠️ Clean the lidar and sensors. Wipe the lidar lens (round glass on top) and the anti-fall sensors (bottom) with a dry wipe.
• 📡 Change Wi-Fi channel. If the robot loses communication with the application, select channel 1, 6 or 11 (they are less loaded) in the router settings).
• 🔧 Reset router settings. Sometimes card problems are caused by conflict. IP-Reboot the router or change it. DNS at 8.8.8.8.

💡 Expert advice: If a robot is constantly confusing the same room, try to separate it with a virtual wall in the app.
