Xiaomi’s robot vacuum cleaners (Mi Robot Vacuum, Viomi, Dreame series) keep maps of the rooms for efficient cleaning. But sometimes these maps become outdated, contain errors or simply interfere after remodeling the apartment. Deleting the map through the Mi Home app (or Xiaomi Home in newer versions) seems like an easy task, but in practice users are faced with hidden menus, synchronization bugs and unobvious steps.
In this article, we will provide the up-to-date 2026 manual covering all Xiaomi robot vacuum cleaners (including Mi Robot Vacuum-Mop 2 Pro, DreameBot L10s Ultra, and others), and discuss not only standard deletion, but also forced card resets through the developer’s settings, as well as what to do if the removal button is inactive or the card is restored after a reboot.
Why You Might Need to Remove Your Vacuum Card
The stored map of the room is the basis of the robot vacuum cleaner, but it's not always perfect. Here are the typical situations where you want to dump it:
- 🏠 Relocation or redevelopment: After repairing or changing the home, the old map becomes useless, and the robot tries to navigate the non-existent walls.
- 🤖 Navigation errors: The vacuum cleaner is constantly “lost”, can’t find a base or gets stuck in one place due to a failure in the map data.
- 📱 Sync failure: The map in the app doesn't update or shows an outdated version despite successful cleaning.
- 🔄 Selling/transferring the device: Before transferring the robot to the new owner, it is recommended to erase all personal data, including cards.
It is important to understand that deleting the map does not affect other vacuum cleaner settings (scheduling, cleaning modes, voice commands), but after reset, the robot will need 2-3 complete cleaning to re-create an accurate map of the room.
Standard method: Delete the card through Mi Home
The easiest method is to use the official app. The instructions are relevant for the Mi Home 6.+.+ and Xiaomi Home 5.+.+ (Android/iOS) versions.
- Open the Mi Home app and select your robot vacuum cleaner from the device list.
- Go to the Map section (usually the home or globe icon in the bottom menu).
- Press three points (⋮) top-right corner of the map screen.
- Select Delete the card (or Reset the card in new versions).
- Confirm the action in the dialog window.
If the item Delete the card is not in the menu, it means:
- 🔹 Your vacuum cleaner model does not support this feature (relevant for older Mi Robots). 1S clone).
- 🔹 Map not yet created (robot hasn't completed first cleaning).
- 🔹 The app is not synced to the device (try reconnecting).
💡
Before deleting the card, check whether the Zone Ban mode or Virtual Walls is active, and these settings are tied to the card and will also be reset.
Alternative methods: reset via robot settings
If the standard method didn’t work, try removing the card through the device settings in the app, a method that is suitable for models with MIUI Robot firmware (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Lite).
- In the Mi Home app, go to your vacuum cleaner page.
- Press the gear (⚙️ Settings) in upper right corner.
- Select General Settings → Reset card (or Card Management).
- Confirm reset. Some models will need to enter PIN-code (default 1234 or 0000).
For Dreame robots (e.g. DreameBot D9), the path may be different:
Settings → Additional features → Map → Delete card dataCheck the battery power (minimum 20%)
Disconnect the robot from the base (if required)
Close the application and restart it
Ensure a stable Wi-Fi connection-->
Forced reset: When the delete button doesn't work
If the card is not deleted through the application interface, the reason may be:
- 🐞 Software failure in the firmware of the robot.
- 📡 Synchronization problems between vacuum cleaner and Xiaomi servers.
- 🔒 Account restrictions (e.g. linking to another region).
In such cases, the hardware reset will help:
- Turn off the vacuum cleaner with a long press on the power button (5-10 seconds).
- Hold the Home + Power buttons at the same time for 10-15 seconds until you hear a beep.
- After the reboot, the robot will create a new map from scratch.
⚠️ Warning: Hardware reset removes all settings, including cleaning schedules, voice commands and zone data. Use this method only as a last resort.
What if the card is restored after resetting?
Delete the map for specific Xiaomi models
Some models have unique features when working with maps, and the table below shows the current data for popular robot vacuum cleaners.
| Model | Support for card removal | Features | Alternative method |
|---|---|---|---|
| Mi Robot Vacuum-Mop 2 Pro | Yes (via map menu) | Save up to 3 cards (for different floors) | Reset via Settings → Map → Management |
| DreameBot L10s Ultra | Yes. PIN-code) | Requires SMS confirmation at first deletion | Use Developer Mode (included by 5-fold press on the software version) |
| Viomi V3 | Partially (through discharge only) | The removal button may not be present in old firmware | Hardware reset (Home buttons + Power) |
| Mi Robot Vacuum 1S | No. | Maps are stored locally, without cloud synchronization | Removal only through complete resetting of settings |
For models with LiDAR (laser scanner), after deleting the map, it is recommended to calibrate the sensors. To do this, place the robot on a flat surface and hold the Start button for 3 seconds.
Frequent mistakes and their solutions
When you delete a card, you're faced with typical problems, and here's how to solve them:
- 🔄 Card returns after deletion: disable cloud sync in Mi Account settings.
- ❌ The button “Delete the card” is inactive: update the vacuum cleaner firmware through Settings → Update of the PO.
- 📵 App doesn't see map: reboot robot and check Wi-Fi connection (should be 2.4GHz, not 5GHz).
- 🔒 Required. PIN-code: default 1234, 0000 or last digit of serial number (on the bottom of the vacuum cleaner).
⚠️ Warning: If the robot stopped responding to commands after deleting the card, reset the network (press the Wi-Fi button on the case for 5 seconds.
💡
Before selling a robot vacuum cleaner, be sure to remove the card and untie the device from your Mi Account. The new owner will not be able to use a vacuum cleaner if it is tied to your profile.
How to speed up the creation of a new card after resetting
Once you delete the old map, it takes the robot time to make a new one, and it speeds up the process.
- Place the vacuum cleaner on the base and make sure it is in an open space (not a niche).
- Start cleaning in Full Cleaning (not zone!) mode.
- Close the doors to other rooms so that the robot scans one room first.
- Avoid moving furniture during the first scan.
For models with cameras (like the DreameBot Z10 Pro), turn on additional lighting to improve object recognition.
Average time of creating an accurate map:
- 🏡 Studio (30 m2): 15-20 minutes.
- 🏠 2-room apartment (60 m2): 30-40 minutes.
- 🏢 Big House (100)+ m2): 1–1.5 hours (zone breakdown may be required).
