Reset the map of the vacuum cleaner Xiaomi through the application: full instructions with nuances

Why you may need to reset your card in a Xiaomi vacuum cleaner

Xiaomi’s robot vacuum cleaner map (Mi Robot Vacuum, Dreame, Viomi series) is not just a route visualization, but the basis for intelligent navigation. Over time, it can become clogged with unnecessary tags, lose relevance after redevelopment of the apartment or start to glitches due to firmware failures. In 80% of cases, cleaning problems (missed areas, chaotic traffic, zoning errors) are solved by resetting the map.

But don't rush to hit Reset the first time you crash. For example, if the vacuum cleaner doesn't keep a new layout after repositioning the furniture, sometimes it's enough to update the map without completely removing it. But when the device stubbornly ignores virtual walls or "lost" in familiar rooms, this is a direct signal to radical measures. Next, we will discuss how to reset the map through the Mi Home (or Mi Home Lite), without disrupting other functions.

Preparation for resetting: what to do in advance

Resetting a card is not just a matter of pressing a button, but if you don't save the key data, you'll have to reconfigure the cleaning areas, virtual walls and schedules, and here's a checklist of the required actions:

Take a picture of the current map in the app (to restore zones)

Write down the names of the rooms and their boundaries (if you use a multi-card)

Check the version of the vacuum cleaner firmware in Settings → About the device

Make sure the robot is connected to Wi-Fi and synced with the app

Charge the vacuum cleaner to at least 50% (to avoid failures during reboot)-->

Pay special attention to multicards (if your model supports several floors), in which case the reset will remove all the saved levels - they will have to be reshooted, and check whether the Do Not Disturb mode is active in the vacuum cleaner settings: it can block changes to the map.

💡

If you have Xiaomi Mi Robot Vacuum-Mop 2 Pro or newer, before resetting, disable the 3D Card function in the settings - this will speed up the process of re-creating the map.

Step-by-step: how to reset the card in Mi Home

The reset algorithm depends on the application version and the vacuum cleaner model, below is a universal instruction for most Xiaomi/Dreame devices (relevant to Mi Home version 6.0+):

1. Open the app and select your vacuum cleaner from the list of devices.
2. Go to the Map section (the house icon in the bottom menu).
3. Press three points (⋮) top-right.
4. Select Reset Card (or Clear Card in Older Versions).
5. Confirm action in the dialog box. The vacuum cleaner will restart (white light will light up).
6. After the reboot, start cleaning in Full Cleaning mode to create a new map.

For models with laser navigation (for example, Xiaomi Mi Robot Vacuum-Mop 2 Ultra) after reset, sensor calibration may be required.

1. Place the vacuum cleaner on a flat surface (without carpets).


2. In the app, select Settings → Additional → Calibration of sensors.




3. Follow the voice prompts (the robot will perform a 360° reversal).

Models with features of resetting the card

Some Xiaomi vacuum cleaners require alternative dumping methods, and the table below shows the key differences for popular models:

Important for Viomi V3 and Dreame Z10 Pro owners, these models often have a card reset via the app that causes the card to fail to save, and in this case, use an alternative method: disconnect the vacuum cleaner from Wi-Fi, then reconnect, which will force the card data to be updated in the cloud.

Frequent Resetting Mistakes and How to Avoid Them

Even following the instructions, users face typical problems.-5 mistakes and their solutions:

• 🔄 Map not updated after reset: Make sure the vacuum cleaner is connected to a 2.4GHz network (5GHz not supported).Reboot the router if the Wi-Fi indicator on the vacuum cleaner flashes red.
• 🚫 Virtual walls gone: It's OK - you have to reconfigure them. At Mi Home, go to Map → Edit → Add a wall.
• ⚠️ Vacuum does not save a new card: Check the free space in the device memory (c Settings) → If less than 10%, remove unnecessary voice packets.
• 🔋 Reset interrupted due to discharge: Connect the vacuum cleaner to the docking station and repeat the procedure. For models without autocharging (such as Mi Robot Vacuum 1) charge to a minimum of 80%.
• 📱 App freezes when reset: Clear the Mi Home cache in your phone's settings or use the web version (home.mi.com).

Once a month

Only after the furniture has been repositioned

When the vacuum cleaner starts to glittle

Never updated.-->

⚠️ Warning: If after resetting the card, the vacuum cleaner stopped responding to commands from the application, check the server region in Mi Home. Russia should be chosen for Russia (MIIT), not China - otherwise synchronization of the map will be blocked.

How to speed up the creation of a new card after resetting

After the discharge, the vacuum cleaner will need 1-3 full cleanings to restore the exact map, and you can speed up the process with these techniques:

1. Use Map mode (if your model has one). It is available in Settings → Cleanup modes and allows the robot to focus only on the scan.
2. Close the doors to unnecessary rooms, remove wires and small objects from the floor, which will reduce time by 30-40%.
3. Adjust the lighting. Laser sensors work better in diffuse light. Avoid direct sunlight or complete darkness.
4. Limit the cleaning area. In Mi Home, draw a time zone (Map → Zone) for the first run, so the map will be created faster.

For LiDAR models (e.g. DreameBot L10 Pro) it is recommended to perform manual calibration after reset:

1. Put the vacuum cleaner in the center of the room.


2. In the app, select Settings → Sensors → LiDAR Calibration.




3. Wait 2-3 minutes (the robot will perform rotation).

💡

If the vacuum cleaner starts to draw curved walls after resetting the map, check the cleanliness of the LiDAR lens (wipe with a dry wipe).

Alternative ways to reset your card (if Mi Home doesn’t work)

If the standard method doesn’t work, try one of these options:

• 🔧 Reset via button on the case: Hold the Power and Home button (if any) for 10 seconds until the orange indicator flashes. Suitable for Xiaomi Mi Robot Vacuum 1 and Viomi V2.
• 📱 Use of third-party applications: For advanced users, Valetudo (requires root access to the vacuum cleaner). Instructions: valetudo.cloud.
• 🔄 Manual firmware update: Download the latest version of the software for your model from miui.su and stitch through Settings → Update → Local file.
• 🔌 Hard reset to factory: In Settings → About the device → Reset. Remove all settings, including schedule and voice commands.

⚠️ Note: When using Valetudo or hand firmware, there is a risk of "bricking" the vacuum cleaner if you choose the wrong version of the software. Before the procedure, check the compatibility of the firmware with your model by serial number (located under the cover of the vacuum cleaner).
