How to reset the room map from the robot vacuum cleaner Xiaomi: full instructions with nuances

Xiaomi’s robot vacuum cleaners are some of the most popular smart cleaning devices, but even they sometimes require a space reset. Over time, a stored map of a room may become obsolete (for example, after rearranging furniture), contain navigation errors or simply interfere with proper operation. Resetting a card is a procedure that helps the device “forget” old routes and create a new, relevant layout of the apartment.

In this article, we will discuss all the ways to reset the map for models Mi Robot Vacuum, Viomi, Dreame and other robots based on Xiaomi, including the nuances for firmware with support for LDS (laser scanning) and VSLAM (visual navigation).

Important: the procedure differs depending on the model and firmware version. For example, Xiaomi Mi Robot Vacuum-Mop 2 Pro resets the card differently than the budget Mi Robot Vacuum-Mop Essential. We covered all relevant scenarios, including the rare cases when standard methods do not work.

Why might you need to reset the card?

Resetting the card is not always a mandatory procedure, but in some cases it significantly improves the vacuum cleaner.

• 🔄 Redesigning the room: you rearranged furniture, added new obstacles (such as a children's playground) or removed old ones. The robot continues to navigate the outdated scheme, which can miss zones or get stuck».
• 🗺️ Mapping errors: The device misrepresents room boundaries, “loses” individual areas, or duplicates them, often after a firmware update or failure during cleaning.
• 🏠 Moving to a new location: if you take a vacuum cleaner to another apartment / house, the old maps will only interfere.
• 🤖 Navigation failures: The robot moves randomly, ignores virtual walls, or constantly forgets the route.
• 📱 Application problems: Mi Home displays an empty map despite a successful scan, or the app issues an error when trying to edit zones.

Some users mistakenly think that resetting the card will help with Wi-Fi connection problems or low suction power. This is not true: the card is responsible only for navigation, and other malfunctions require separate diagnosis.

Method 1: Reset the card via the Mi Home app (main method)

The easiest and recommended way is to use the official Mi Home app (or Xiaomi Home for newer versions), which is suitable for most models, including the Mi Robot Vacuum-Mop 2 Lite, Viomi V3, Dreame D9 and others.

Steps:

1. Open Mi Home and select your robot vacuum cleaner on the home screen.
2. Go to the Map section (or Map in English).
3. Press three points (⋮) in the upper right corner and select Delete the card (or Clear Map).
4. Confirm the action. The robot will beep and begin the cleaning process.

Once reset, the device will automatically start a new scan when the next cleaning starts, and if the option to delete the card is missing, then your model does not support saving cards (for example, some budget versions without LDS).

Make sure the robot is connected to Wi-Fi|Close all background apps on your phone|Check the firmware version of the robot (current - not lower than 3.5.8)|Delete the Mi Home app cache (if the map is not displayed)-->

Method 2: Hardware reset (buttons on the body)

If the app doesn’t work (e.g., the robot is off Wi-Fi) or the Mi Home reset doesn’t work, you can use physical buttons on the case, which is suitable for most Xiaomi models, but doesn’t work on firmware 1400+ devices (there, the card reset is blocked at the hardware level).

Instructions:

1. Turn off the robot by pressing the power button for 3 seconds.
2. Hold the Home and Power buttons for 10-15 seconds at the same time until you hear a double beep.
3. Release the buttons. The robot will reboot, and the map will be reset.

⚠️ Note: on some models (for example, Mi Robot Vacuum-Mop P), long-term retention of buttons leads to a complete reset of settings, not just the map. To avoid this, watch for sound signals: single squeak - reset the card, double - reset to factory settings.

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

Some Xiaomi robot vacuum cleaners (such as Mi Robot Vacuum-Mop 2 Pro or Dreame Bot W10) support control via voice assistants. A reset can be initiated by a team, but this method works unstable and depends on regional settings.

Examples of teams:

• 🎤 «Alice, drop the card from Mi Robot" (requires the device to be tied to Yandex.Smart Home).
• 🎤 «Okay, Google, clean the Xiaomi vacuum cleaner map (you need to connect via Google Home).

Limitations of the method:

• ❌ It only works for cloud-enabled devices. API (Check out the Mi Home Settings section Voice assistants).
• ❌ Commands may not be recognized if the robot is not connected to the Internet.
• ❌ Not all models support voice reset (e.g. Viomi). V2 They don’t respond to such teams).

💡

If the voice assistant doesn't recognize the command, try re-phrasing it, for example, instead of "reset the card," say "remove the room map" or "clear the saved card."

What to do if the card is not reset?

Sometimes standard methods don't work. Let's look at the typical problems and their solutions.

If none of the methods worked, try a forced firmware update:

1. Download the latest version of the software for your model from the official Xiaomi website.
2. Unpack the archive and place the.pkg file in the root of the microSD card (if your model supports installation from the memory card).
3. Insert the card into the robot, hold the Power button until the beep and wait for the update to complete.

💡

If the robot starts to move randomly or ignore obstacles after resetting the card, the gyroscope or impact sensor is likely damaged, and a diagnostic at the service center is required.

How can we speed up re-mapping?

Once the map is reset, the robot will need time to rescan the room, and to make the process faster and more accurate, follow these tips:

• 🕒 Start scanning in the daytime: sensors VSLAM They work better in good light. In the dark, a robot can skip sections.
• 🚪 Close the doors, and this will help the robot define the boundaries of the rooms, and open openings can lead to the "merging" of zones on the map.
• 🧹 Remove small objects from the floor: wires, toys or shoes can disrupt navigation.
• 📶 Provide stable Wi-Fi: If the signal is interrupted, the robot can interrupt the scan. Use a repeater if some rooms are weak.

The average full scan time for an apartment of 50-70 m2 is 15-25 minutes.

• Battery charge (should be at least 50%).
• Sensor cleanliness (dust on the LDS-sensor distorts data).
• No interference from other devices (for example, wireless headphones running at 2.4 GHz).

Models with features of resetting the card

Some Xiaomi robot vacuum cleaners have unique nuances when resetting a map. We put them together in a table:

⚠️ Warning: If you are using a robot vacuum cleaner with hybrid navigation (LDS + VSLAM, Like Dreame Bot. Z10 Pro, after resetting the card, it may be necessary to calibrate the camera:

1. Place the robot on a flat surface under bright light.
2. In the Mi Home app, go to Settings → Sensor Calibration.
3. Follow the instructions on the screen (the robot will make a series of sounds and perform a 360° rotation).

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: this can damage the robot's file system.Always stop cleaning before resetting.
• ❌ Use of informal firmware: custom software (such as Valetudo) can block standard reset methods, in which case manual deletion of cards through the use of a mobile device is required. SSH.
• ❌ Ignoring updates: If the robot's firmware is outdated, resetting the card may not work.
• ❌ Reset via third-party applications (e.g. Home Assistant): This can result in loss of communication with the robot.

To minimize the risks, follow this algorithm:

1. Stop cleaning and bring the robot back to base.
2. Make sure the battery is above 30%.
3. Use only one reset method (do not combine buttons and app).
4. After reset, wait for the robot to fully restart (about 1-2 minutes).

💡

If the robot stopped responding to commands after resetting the card, try reconnecting it to Wi-Fi manually: hold the Power + Home button until the Wi-Fi indicator flashes (about 5 seconds), then set up the connection again in Mi Home.
