How to Reset Xiaomi Vacuum Card: Full Instruction for All Models

Xiaomi’s robot vacuum cleaners (including the Dreame, Viomi and Mijia brands) use laser or optical sensors to map a room, which can become obsolete, contain errors, or interfere with the device’s proper operation over time, and resetting a card is a standard procedure that must be performed after redevelopment, moving or navigational failures.

In this article, you will find the latest ways to reset cards for all popular models of Xiaomi vacuum cleaners (including Mi Robot Vacuum-Mop). 2 Pro, DreameBot Z10 Pro, Viomi V3 And others, and also solutions to the typical problems that arise after data cleaning. Home/DreameHome, Hidden engineering teams for advanced users.

Why You May Need to Reset Your Vacuum Card

The room map is not just a drawing in an application, it's the basis for the robot's navigation algorithms, and it's reset in a few cases:

• 🔄 The layout of the apartment has changed, with furniture being moved, renovated or new partitions added, and the old map will prevent the vacuum cleaner from navigating.
• 🤖 The vacuum cleaner “lost” or cleans the same areas: if the robot constantly returns to the base, not reaching the end of cleaning, or ignores some rooms – the map could be damaged.
• 📱 Application errors: the map is displayed incorrectly (blurred, with artifacts) or not updated after changes.
• 🏠 Moving to a new location: Even if the layout is similar, the algorithms LDS (laser scanning) or VSLAM (visual navigation requires new calibration.
• 🔧 After a firmware update: Some updates reset navigation settings automatically, but sometimes manual cleaning is required.

It is important to understand that resetting the card does not remove other vacuum cleaner settings (cleaning schedule, no-go zones, voice commands). D9 Xiaomi S7), You will have to re-store floors or rooms.

⚠️ Note: If your vacuum cleaner uses hybrid navigation (laser) + camera, like in Viomi V2 Pro, after resetting the card, he will need to 2-3 complete cleaning for precise calibration, during this period avoid moving furniture.

Ways to reset the card: from simple to complex

There are three main methods of cleaning the map in Xiaomi vacuum cleaners: Start with the simplest and move on to the next ones if the previous one didn’t work.

1.Reset via Mi Home/DreameHome app

This is the safest and most recommended way for most users, and the instructions are suitable for all models that support official applications:

1. Open the Mi Home app (or DreameHome for Dreame vacuum cleaners).
2. Select your vacuum cleaner from the list of devices.
3. Go to the Map section (or Map in English).
4. Press three points (⋮) in the upper right corner and select Clear Map).
5. Confirm the action in the dialog window.

In some models (for example, Xiaomi Mi Robot Vacuum-Mop P), the option may be called Reset the card or Delete the card data. Once confirmed, the vacuum cleaner will restart, and the next time it is turned on, it will start building a new map from scratch.

Make sure the vacuum cleaner is connected to Wi-Fi

Close all doors to rooms that do not need to be scanned

Remove small objects (toys, wires) from the floor

Check the battery charge (should be) >30%)-->

Hardware reset (button on the body)

If the app doesn’t respond or the vacuum cleaner doesn’t connect to the network, you can use a physical reset button, which works for most Xiaomi and Dreame models, but is not suitable for Viomi vacuum cleaners (they have a different reset logic).

Instructions:

1. Turn off the vacuum cleaner with a long press on the power button (3-5 seconds).
2. Find a small hole on the case with an inscription RESET (usually near the power button or under the battery cover).
3. Take a paperclip or toothpick and press the button inside the hole on 5-10 seconds until you hear the beep.
4. Release the button and turn the vacuum cleaner on again.

After the hardware reset, the vacuum cleaner will lose all settings, including Wi-Fi connection, cleaning schedule and saved voices, a method that should only be used as a last resort if the software reset has not worked.

⚠️ Note: Xiaomi Mi Robot Vacuum models 1S and DreameBot D9 button RESET It only resets network settings, not a map. To clean up the data, use a button combination: hold home. + Turn on 10 seconds.

3. Engineering teams (for advanced users)

If standard methods don’t work, you can use hidden commands via a console or special button sequences, which is suitable for MiOT-based firmware models (e.g., Xiaomi Mi Robot Vacuum-Mop 2 Lite).

To perform engineering commands:

1. Connect the vacuum cleaner to Wi-Fi and make sure it is on standby on base.
2. Open the Mi Home app and go to Device Settings → About the device.
3. Click 5 times in a row on the firmware version until the Engineering Mode menu appears.
4. Enter a command to reset the card: map_reset or to reset the settings completely: factory_reset

Once the command is entered, the vacuum cleaner will restart. In some models (DreameBot) W10) Instead of text command, a button combination is used: Spot → Home → Power (hold 3 seconds).

Resetting the card on popular models: features

Despite the general principles, some Xiaomi vacuum cleaners have unique nuances of resetting the card, the table below summarizes the current data for the most common models:

For Xiaomi models with support AI-Maps (e.g. Mi Robot Vacuum-Mop 2 Ultra) may require AI training after reset: During the week, the vacuum cleaner will analyze your cleaning preferences (frequency, zones) and optimize routes.

💡

If the vacuum cleaner thinks long before cleaning, put it on the base and restart (hold the power button for 10 seconds) this will reset the navigation data cache and speed up the construction of a new map.

What to do if the card is not reset

Sometimes users are faced with a situation where the card is not cleared either through the application or hardware reset.

• 📵 The vacuum cleaner is not connected to Wi-Fi: without the Internet, the application cannot send a command to reset. Connect the device to the network or use a hardware method.
• 🔄 Outdated firmware: older versions of the software may not have the option to reset the card. Update the firmware through Settings → Update of the PO.
• 🛠️ Damaged file system: If the vacuum cleaner is constantly restarting or does not save the settings, a complete reset to the factory (team) is required. factory_reset engineer).
• 📱 In-app error: Try reinstalling Mi Home or using alternative software such as Home Assistant.
• 🔋 Battery discharge: at a charge level below 20% Some models block the changes in settings. 1-2 hour.

If none of the methods worked, check the error logs in the Engineering Menu (System Log section). MAP_ERR_0x03 or NAVI_FAIL They're pointing out hardware problems with the navigation sensors, and you're going to need to call the service center.

⚠️ Note: Xiaomi vacuum cleaners with firmware up to version 3.5.8 (released in 2021) may not have the option of resetting the card in the application. For such models, use a button combination: hold Spot Cleaning + 15 seconds before the Wi-Fi indicator flashes.

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

After cleaning the map, the vacuum cleaner will need time to restore it, and to speed up the process and improve navigation accuracy, follow these recommendations:

1. First manual cleaning: run the vacuum cleaner in Zone Cleaning mode and direct it to the largest room, which will help the algorithm determine the size of the room.
2. Good lighting: for models with cameras (Viomi, DreameBot) W10) Turn on the lights in all rooms — 200-300 suite.
3. Minimize interference: remove mirrors, glass and shiny surfaces from the floor – they distort the laser scanning.
4. Use beacons: If the vacuum cleaner supports Mi Beacon (e.g. Xiaomi Mi Robot Vacuum-Mop 2), install beacons in the corners of the room for precise anchorage.
5. Don't interrupt the cleaning: let the vacuum cleaner complete the full cycle.A premature return to base can lead to a fragmented map.

For supported models 3D-maps (DreameBot) X30 Ultra) after discharge, it is recommended to perform a calibration of the height:

1. Place the vacuum cleaner on a flat surface (for example, tiles).
2. In the app, go to Settings → Additional → Calibration of sensors.
3. Follow the instructions on the screen (usually you need to raise and lower the vacuum cleaner 3 times).

💡

For vacuum cleaners with laser sensor (LDS) Avoid direct sunlight during the first cleaning – this can temporarily blind the sensor and lead to mapping errors.

Frequent Mistakes and How to Avoid Them

When you reset a card, users often make mistakes that lead to additional problems, and here are the most common ones:

• 🚫 Resetting the card during cleaning: if you clean the data while the vacuum cleaner is running, it can "hang" in the middle of the room.
• 🔌 Shutting off the network during reboot: After reset, the vacuum cleaner updates navigation data – interrupting this process can lead to an error NAVI_INIT_FAIL.
• 📲 Use of informal firmware: custom software (such as Valetudo) may conflict with standard map-building algorithms.
• 🏠 Resetting the card without reference to the base: if the vacuum cleaner is not standing at the docking station, it may lose the coordinates of the "home" and not find its way back.
• 🔄 Frequent resets: If you clean the map once a week, the navigation algorithms don't have time to optimize.

If after the discharge the vacuum cleaner began to ignore the virtual walls or does not recognize the rooms, check:

• Settings of zones in the application (possibly they were reset with the map).
• Location of the base – if it is moved, the vacuum cleaner will be disoriented.
• Firmware version – in some updates, the logic of virtual barriers changes.
