How to reset the card in the robot vacuum cleaner Xiaomi: all the ways and nuances

Xiaomi’s robot vacuum cleaners are smart assistants that save you time, but sometimes their navigation system starts to malfunction. One of the common problems is a flawed map of the room, which causes the device to skip areas, get stuck or clean the same areas several times, in which case a full map reset helps – a procedure that forces the vacuum cleaner to rescan the room and create an up-to-date circuit.

In this article, you will find step-by-step instructions for all popular models, from the budget Mi Robot Vacuum to the flagship DreameBot and Viomi. We will discuss how to reset the card through the Mi Home app, physical buttons on the case, and what to do if the reset does not help.

Important: the reset procedure varies depending on the firmware version and model. If your vacuum cleaner is released before 2020, some methods may not work, which we will mention as well.

Why you should reset the map and when to do it

The map of the room is the basis of Xiaomi's laser and hybrid vacuum cleaners, which not only stores the plan of the room, but also data on obstacles, cleaning areas, virtual walls.

• 🔄 Changes in the interior - rearrangement of furniture, new items that the vacuum cleaner does not recognize.
• 📱 Sync errors – if the Mi Home app hasn’t updated the map for several weeks.
• 🤖 Sensor failures - laser rangefinder (LDS) Or the gyroscope starts to give incorrect data.
• 🔋 Updates to firmware – after the software upgrade, the old card may conflict with new algorithms.

Signs that it is time to reset the card:

• 🚫 The vacuum cleaner sees no new obstacles and faces them.
• 🔄 It misses areas that were previously cleaned.
• ⏳ It moves chaoticly, as if it had lost its orientation.
• 📵 The app displays an empty or distorted map.

⚠️ Warning: If the vacuum cleaner creates it again with errors after resetting the card, the problem may be the contaminated one. LDS-a sensor (laser under the glass cover on top) wipe it with a soft napkin without pile.

Method 1: Reset the card via the Mi Home app (for most models)

It is the simplest and most versatile method that works on Mi Robot Vacuum-Mop 2 Pro, DreameBot. D9, Viomi V3 and other models with support for Mi Home or DreameHome. Instructions are relevant for firmware in 2021 and newer.

Steps:

1. Open the Mi Home app and select your vacuum cleaner.
2. Go to the Map (or Cleaning) section → Map in new versions).
3. Press three points (⋮) top-right.
4. Choose Reset Card or Clear Card (name depends on the model).
5. Confirm the action - the vacuum cleaner will emit an audible signal and begin a new calibration.

After discharge:

• 🤖 Start cleaning in Full cleaning mode - a new map has been created.
• 📱 Wait until the current plan is displayed in the application (may take 5-15 minutes).
• ⚙️ Reconfigure virtual walls and cleaning areas – they too will reset.

⚠️ Note: Some models (e.g. Mi Robot Vacuum) 1S) After resetting the card, you may need to reconnect to Wi-Fi. check the password from the network in advance.

Make sure the vacuum cleaner is connected to Wi-Fi

Close all doors in the room (so that there are no drafts)

Put the vacuum cleaner at the charging station

Check the battery power (should be >20%)

Method 2: Hardware reset (buttons on the body)

If the app doesn't see the vacuum cleaner or the map isn't reset software, you can use physical buttons on the case, which works on all models, including the old Mi Robot Vacuum 1 and Mi Robot Vacuum-Mop Essential.

Instructions:

1. Turn off the vacuum cleaner with a long press on the power button (3-5 seconds).
2. Press the buttons at the same time (🏠) and food (⏻) 10-15 seconds until you hear a beep.
3. Release the buttons and the vacuum cleaner will start rebooting.
4. After turning on, start cleaning to create a new map.

Some models (such as DreameBot) Z10 Pro) other combination:

• 🔄 Squeeze the power. + Cleaning mode for 10 seconds.
• 📛 After the signal, release – the Reset Map message will appear on the display.

⚠️ Note: On vacuum cleaners with a display (for example, DreameBot) L10 Pro) a hardware reset may cause all settings to be reset, including the cleaning schedule.

Method 3: Reset via the Engineering Menu (for advanced users)

Some Xiaomi models have a hidden engineering menu where you can force the card to be erased without completely resetting. W10 and other Rockrobo-based devices.

How to open the engineering menu:

1. Make sure the vacuum cleaner is connected to Wi-Fi and charged at 50%+.
2. Press the buttons sequentially: Power → Home. → Nutrition → Increased capacity → Power (interval between pressings - 1 second).
3. The vacuum cleaner will give a double signal - the menu is activated.
4. In the Mi Home app, go to Settings → About the device → Firmware version.
5. Click on the firmware number 10 times in a row and Engineer Mode will open.
6. Select Map Reset and confirm.

Advantages of this method:

• ⚡ Does not affect other settings (scheduling, voice packets).
• 🔧 Allows you to calibrate sensors (Sensor Calibration option).
• 📊 Provides access to error logs (useful for diagnosis).

💡

If the engineering menu doesn’t open, try using an alternative app – Valetudo (for open firmware). API). It gives more options for map management, including manual zone editing.

Frequent Card Reset Mistakes and How to Avoid Them

Even after a successful card reset, the vacuum cleaner may not work properly.

If none of the methods helped, the reason may be a hardware malfunction:

• 🔋 Discharged battery – vacuum cleaner does not have time to save the card.
• 🤖 Damaged. LDS-sensor – requires replacement (cost) ~1500–3000 ₽).
• 📱 Controller Failure – You Need to Flash Through USB (Only for experienced users).

💡

If the vacuum cleaner behaves as strangely after resetting the card as it did before, the problem is not with the map, but with the sensors or the firmware, and then only diagnostics at the service center will help.

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

Once the map is zeroed, the vacuum cleaner will need 1-3 cleanings to accurately display the layout of the room.

1. Prepare the room: 🚪 Close all doors – drafts interfere with laser scanning. 🪑 Remove small objects (wires, toys) from the floor). 💡 Turn on the lights – sensors work better in bright light.
2. Set up the vacuum cleaner: 📶 Connect it to 2.4GHz Wi-Fi (5GHz unstable for mapping). 🔋 The battery should be charged. >50%. 🎯 Run the cleaning in Standard Mode (not Turbo – there the vacuum cleaner moves too fast for accurate scanning).

Control the process:

• 📱 Follow the construction of a map in real time in the application.
• 🛑 If the vacuum cleaner is stuck, transfer it manually and press Continue.

Advice for owners of DreameBot and Viomi:

• 🤖 Enable the option of Improved Mapping in the settings (if any).
• 📏 Use manual separation of rooms after the first cleaning - this will help the vacuum cleaner to quickly "remember" the layout.

Models on which resetting the card works differently

Some Xiaomi vacuum cleaners have unique mapping algorithms, and here are the features for popular models:

For DreameBot with AI.Map 2.0 (e.g. DreameBot) X30) after resetting the card is recommended:

1. Run cleaning in Deep mode for more accurate scanning.
2. Enable the option Auto Update the map in the settings.
3. If the map is still curved, calibrate the gyroscope through the engineering menu.
