Xiaomi's robot vacuum cleaners are some of the most popular smart cleaning devices, but their room maps sometimes require a reset, maybe you moved, made repairs, or the device started to misorientate because of errors in the stored map, and in any case, removing the old map is a necessary step for the vacuum cleaner to work properly.
In this article, we will discuss all the available ways to delete the card in the Mi Home app, including hidden settings and solutions for cases when a standard reset does not work, and learn how to avoid typical errors and what to do if the card recovers itself after a reboot.
The instructions are valid for Mi Robot Vacuum, Viomi V2/V3, Dreame Bot and other robot vacuum cleaners running through Mi Home. If your model uses a proprietary app (like Dreamehome), some of the features may differ, as we will mention.
Why might I need to delete the card?
A stored map of the room is not just a "photo" of your apartment, but a complex coordinate system that the vacuum cleaner navigates, and over time, it can become a source of problems.
- 🏠 Changes in layout: Rearrangement of furniture, repairs, or even new carpets can confuse a vacuum cleaner if it tries to follow an outdated map.
- 🤖 Navigation errors: Robot starts to “lose”, skips cleaning areas or gets stuck in one place due to incorrect map data.
- 📱 Application crashes: After updating the Mi Home or vacuum cleaner, the map may not be displayed correctly or saved.
- 🔄 Transfer or transfer of the device: If the vacuum cleaner is sold or transferred to another user, it is better to remove the old card for privacy reasons.
It is important to understand that deleting a card is not the same as resetting a vacuum cleaner to a factory one. The card is stored separately from the basic parameters (such as cleaning schedule or suction force), so it can be cleaned without losing other data.
Method 1: Standard card removal via Mi Home
The easiest method is to use the app’s built-in features. It works for most Xiaomi models, including the Mi Robot Vacuum-Mop 2 Pro, Viomi V3, and others.
Instructions:
- Open the Mi Home app and select your robot vacuum cleaner on the home screen.
- Go to the Map section (usually the home icon or map icon in the bottom menu).
- Press three points (⋮) top-right corner of the map screen.
- In the drop-down menu, select Delete the card (or Clear the map, depending on the version of the application).
- Confirm the action in the dialog window.
After that, the vacuum cleaner will start cleaning from scratch, creating the map again. Note that some models (such as the Dreame Bot Z10 Pro) may require additional confirmation through a physical button on the case.
Make sure the vacuum cleaner is connected to Wi-Fi
Close all active cleaning tasks
Check the battery charge (at least 20%)
Take a screenshot of the current map (in case of recovery)-->
⚠️ Note: If the card appears again after deleting the next turn on, this may indicate data caching in the Xiaomi cloud.
Method 2: Reset the card through the device settings
If standard removal doesn’t work, you can try resetting the card through the vacuum cleaner settings menu, a method that is suitable for models with advanced options such as the Mi Robot Vacuum-Mop P or Viomi SE.
Steps:
- In the Mi Home app, go to the section of your vacuum cleaner.
- Press the gear icon (⚙️) in the upper right corner to open the device settings.
- Scroll down and find the Map or Navigation section (the name may vary).
- Choose Reset the card or Restore the factory card settings.
- Confirm the action. Some models will require input. PIN-code (default 1234 or 0000).
This is a deeper approach than simply removing the map menu, as it cleans not only the visual display but also the internal navigation data, but it does not affect other vacuum cleaner settings (such as schedules or voice commands).
| Model vacuum cleaner | Does resetting the card through settings support? | Is PIN required? |
|---|---|---|
| Mi Robot Vacuum-Mop 2 Pro | Yes. | No. |
| Viomi V3 | Yes. | Yes (1234) |
| Dreame Bot D9 | Partially (only via Dreamehome) | Yes (0000) |
| Mi Robot Vacuum 1S | No. | — |
⚠️ Warning: On some firmware after resetting the card, the vacuum cleaner may freeze during the calibration stage. If this happens, restart the device by holding the power button for 10 seconds.
Method 3: Completely resetting the vacuum cleaner to factory settings
If the first two methods didn't work, there's a radical solution, hard reset, which will remove not only the map, but all the device settings, including schedule, cleaning areas, and suction options, and only use this as a last resort!
How to perform the reset:
- Turn off the vacuum cleaner by holding the power button for 5 seconds.
- Hold the power and home buttons (or Spot Cleaning, depending on the model) for 10-15 seconds at the same time until you hear the beep.
- Release the buttons. The vacuum cleaner will reset and return to factory settings.
- Connect the device to Mi Home again, as after the first setup.
Once reset, the vacuum cleaner will work like a new one, and the first cleaning will create a fresh map. Note that some models (for example, the Viomi V2) will require re-association with the Xiaomi account.
What to do if the vacuum cleaner is not discharged?
Important: Laser rangefinder (LDS) vacuum cleaners may require recalibration of the sensor after reset, leaving the device on a flat surface for 1-2 minutes after switching on.
Frequent problems and their solutions
Even after deleting the map, users face unexpected difficulties.
- 🔄 The card is restored after rebooting: this means that the data is synchronized with the Xiaomi cloud.The solution is to disable cloud sync in the application settings or use method 3 (full reset).
- 📵 The vacuum cleaner does not create a new map: check if the sensors are closed (especially if the sensors are closed). LDS-Also make sure there is enough lighting in the room - some models don't work well in the dark.
- ⚠️ Failed to save card error: reinstall the Mi Home app or clear its cache in your phone's settings. On Android, this is done in Settings → Annexes → Mi Home → Memory. → Clear the cache.
If the vacuum cleaner starts to “go around” or ignore the cleaning areas after removing the card, this may indicate damage to the firmware, in which case only flashing through the Mi Home or the service center will help.
💡
Before you delete the card, export the screenshot to the cloud (Google Drive, iCloud) or send it to your own mail, which will help restore the cleaning areas if the new map is created with errors.
How to avoid problems with the map in the future
To avoid having to reset the card often, follow these recommendations:
- 📲 Regularly update your firmware: newer versions often fix navigation bugs. Check for updates to your device settings → Firmware update.
- 🏡 Do not move the vacuum cleaner to another room during cleaning: this will knock out the algorithms of map construction.
- 🔋 Keep an eye on battery power: if the vacuum cleaner runs out during map creation, the data may not be stored correctly. The minimum charge for the first cleaning is 50%.
- 🌐 Use stable Wi-Fi: communication interruptions during card synchronization cause damage. If the router often "falls", switch the vacuum cleaner to 2.4 GHz (5 GHz may be unstable).
For multi-card models (like the Dreame Bot L10 Pro), you can save separate maps for each floor, in which case you only need to delete the one that is outdated without affecting the rest.
Alternative ways to manage the map
If standard methods don’t work, try these options:
- 🖥️ Mi Home web version: some features (e.g. map editing) are only available in the browser version of home.mi.com. Sign in to your account and check the card settings.
- 🤖 Voice commands: for vacuum cleaners with Alice support or Google Assistant, you can try the “Clear Map” command (does not work on all models).
- 📱 Third-party applications: for example, Valetudo (for hardwired devices) allows you to manage the card at a low level. However, this requires unlocking root access and is only suitable for advanced users.
For Dreame vacuum cleaners that work through the Dreamehome app, the card removal process is similar, but the menu may be called differently (e.g. Clear Map instead of Delete Map).
💡
If the vacuum cleaner is unstable after removing the map (for example, does not return to base), calibrate the compass. To do this, place it on a flat surface and rotate around its axis 360° manually.
