How to add a new room to the map of the vacuum cleaner Xiaomi: instructions for all models

Xiaomi Robot Vacuum (including Mi Robot Vacuum, Viomi) V3, Dreame D9 And others use laser or optical sensors to map the space, but what if you've redesigned, added furniture, or just wanted to divide the space into zones for more efficient cleaning? Adding a new room to a vacuum cleaner card is a procedure that requires understanding how algorithms work. SLAM (Simultaneous localization and mapping) and features of the Mi Home or Xiaomi Home app.

In this article, we will look at all the ways to add a room, from automatic scanning to manual map editing, and also look at the typical errors that lead to the “loss” of new spaces after restarting the vacuum cleaner.

1. Preparation of the vacuum cleaner for updating the map

Before adding a new room, make sure the vacuum cleaner is ready for rescanning, which is especially important for models with LiDAR (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Pro or DreameBot). L10 Pro) where the laser module must be clean and not closed.

Here's what you need to do in advance:

• 🧹 Clean the sensors: wipe the LiDAR lens with a dry wipe (under the top cover). V2 Pro) check the lens.
• 🔋 Charge the battery: the charge level must be at least 50%, otherwise the vacuum cleaner may interrupt the scan.
• 🚪 Access: Open all doors to new spaces, remove small objects from the floor that may interfere with movement.
• 📶 Check Wi-Fi: The vacuum cleaner must be connected to a 2.4 GHz network (5 GHz is not supported by most models).

If you are using a Hybrid Navigation Vacuum (LiDAR) + A DreameBot camera Z10 Pro, additionally check the lighting in the new room. Dim light or direct sunlight can distort the data from the camera.

2. Ways to add a new room

There are three main methods of adding a room to the map of the Xiaomi vacuum cleaner. The choice depends on the model and version of the firmware:

1. Automatic scanning – the vacuum cleaner detects new rooms during cleaning.
2. Manual map editing – the user manually draws walls and zones in the app.
3. Resetting the card with subsequent rescanning is a radical method for complex cases.

Let's look at each one in detail.

Automatic scanning (recommended method)

This is the easiest way that works for most models with LiDAR.

1. Run the vacuum cleaner in mapping mode (in some models - zone cleaning).
2. Open access to a new room and wait for the robot to examine it.
3. After cleaning, check the map in the Mi Home app – the new room should appear automatically.

If the room is not displayed:

• 🔄 Repeat the scan 2-3 times (sometimes it takes multiple passes to fix the changes).
• 📱 Update the vacuum cleaner firmware through Settings → Update of the PO.
• 🛠️ Check if sensors block objects (such as a high threshold or mirrored surfaces).

💡

If a vacuum cleaner ignores a new room, try temporarily installing a virtual wall in the app and then removing it after scanning, which sometimes "wakes up" the mapping algorithm.

Manual editing of the map

If the automatic scanning fails, you can manually adjust the map, which is suitable for all models that support card saving (for example, Xiaomi Mi Robot Vacuum-Mop P, Dreame). D9 Max).

Instructions:

1. Open the Mi Home app → Choose your vacuum cleaner → Go to the Map section.
2. Click on the Edit icon (pencil or three dots in the upper right corner).
3. Choose the tool Add room or Draw wall.
4. Circle the outline of the new room by following the hints in the app.
5. Save the changes and start a test cleaning.

Please note:

• 📏 The accuracy of the manual editing depends on the scale of the map. If the room is drawn crooked, the vacuum cleaner may not see it".
• 🔄 After manual editing, a vacuum cleaner restart is sometimes required (reset button on the case).

2.3. Reset the map from scratch

If previous methods didn't work, you'd have to reset the map and get the vacuum cleaner to build it again, which is a last resort, because you'd have to adjust all the zones and rooms from scratch.

How to reset the card:

1. In the Mi Home app, go to the vacuum cleaner settings → Map. → Reset the card.
2. Confirm the action.
3. Run the vacuum cleaner in Full Cleaning mode and wait for the scan to be completed.

After discharge:

• 🔍 A vacuum cleaner can “forget” old rooms – they will have to be reconfigured.
• ⚠️ Do not interrupt the first scan, otherwise the map may be fragmentary.

3. Set up zones and virtual walls for a new room

Adding a room is only half the battle, and in order for a vacuum cleaner to clean effectively in a new room, you need to set up cleaning areas and virtual restrictions.

The Mi Home or Xiaomi Home app has the following tools available:

• 🟦 Cleaning areas – highlight the area that the vacuum cleaner should clean more often (for example, near the front door).
• 🚫 Virtual walls – block access to certain areas (useful for children’s rooms or areas with wires).
• 🔄 Cleaning routes – set the order of the room (not available on all models).

Example of settings for a new room:

1. Open the map in the app and click Add Zone.
2. Round the new room.
3. Set the cleaning parameters: 🧽 Mode: dry/wet cleaning. 🔢 Intensity: Standard/Deep. ⏱️ Schedule: daily/days of the week.

Important: if you use a vacuum cleaner with a wash function (such as Xiaomi Mi Mop 2 Ultra), do not turn on wet cleaning in the new room until you check the tightness of the floor. Laminate or parquet can swell from excess moisture.

4.Typical mistakes and how to avoid them

Even after a successful addition to a room, users often face problems, and here are the most common mistakes and solutions:

⚠️ Note: If the vacuum cleaner Xiaomi after adding a new room begins to "lose" and chaoticly drive around the apartment, this is a sign of a conflict of cards. → Reset the map and rescan the room again.

Let’s look at other typical problems:

• 🚪 Vacuum Won't Hit a New Room: Check the Threshold height - the maximum for most Xiaomi models is 2cm. Make sure there's enough lighting in the room (relevant for models with cameras).
• 🗺️ New room is shown curved or not in scale: Reboot the vacuum cleaner (hold the Power button for 10 seconds). Remove the room and draw it again manually.
• 🔄 After the firmware update, the room disappeared: This is a known bug for vacuum cleaners on firmware below 3.5.8. Update the software via Mi Home. If the room doesn't recover, reset the map.

Another common problem is that the vacuum cleaner ignores the virtual walls in the new room, and it's because of:

• 📱 Unsaved changes to the app (always click Save after editing).
• 🔋 Low battery charge (virtual walls only work at a charge level above 20%).
• 📡 Bad Wi-Fi signal (vacuum cleaner must be constantly in communication with the Xiaomi server).

💡

If the Xiaomi vacuum cleaner starts to “hang” or give out a map error (32) after adding a room, check if the new room conflicts with existing zones. Remove all overlapping virtual walls and reboot the device.

5. Features for different models of vacuum cleaners Xiaomi

Mapping algorithms vary depending on the model, and here are the key nuances for popular devices:

Vacuum cleaners with LiDAR (laser scanner)

Xiaomi Mi Robot Vacuum-Mop 2 Pro, DreameBot L10 Pro, Viomi V3 Max.

Advantages:

• 🎯 High accuracy of mapping (accuracy up to 1-2 cm).
• 🔄 Automatically detect new rooms in 90% of cases.
• 📊 Support for multi-level maps (for two-storey apartments).

Disadvantages:

• 💡 Sensitivity to direct sunlight (can distort LiDAR data).
• 🚫 Does not work in complete darkness (minimum lighting required).

Vacuum cleaners with cameras and gyroscopes

Xiaomi Mi Robot Vacuum-Mop Essential, Viomi V2 Pro, Dreame D9.

Advantages:

• 💰 Lower price.
• 🌓 They can work in the dark (using gyroscopes).

Disadvantages:

• 📏 Low accuracy of maps (accuracy up to 10-15 cm).
• 🔄 Manual room adjustments are often required.
• 🚫 Do not support saving cards (when power is turned off, the card is reset).

For such models, adding a new room usually boils down to:

1. I'll reset the current map.
2. Run a full scan.
3. Manual allocation of cleaning areas (without reference to specific rooms).

Supported vacuum cleaners 3D-map

Xiaomi Mi Robot Vacuum-Mop 2 Ultra, DreameBot X30 Ultra.

These devices are used 3D-Scanners like ToF sensors to build a three-dimensional map of a room, and the easiest place to add a new room is to create a new one:

1. The vacuum cleaner automatically detects changes in the layout.
2. You can view the rooms in the app 3D And edit them according to the height of the furniture.
3. It supports object recognition (such as chairs or shoes), making it easier to set up virtual walls.

But 3D-The models have their own nuances:

• 🖥️ They require a more powerful processor, so they can “brake” with a large number of rooms.
• 📦 They may mistakenly recognize large objects (such as boxes) as walls.

6. Optimizing cleaning after adding a room

By adding a new room, be sure to optimize your cleaning routes, which will save battery life and time.

Optimization tips:

• 🔄 Set up the order of cleaning: in the Mi Home application you can set the sequence of the room walk (for example, first the corridor, then the bedroom).
• ⏱️ Use a schedule: Start cleaning a new room when no one is there (for example, during working days).
• 🧹 Divide the room into zones: if the room is large, break it into 2-3 zones with different cleaning frequency.
• 🔋 Keep an eye on charge: If the new room is far from the dock, set up a virtual recharging area in the middle of the route.

An example of the optimal schedule for an apartment with 4 rooms:

⚠️ Attention: If you add a room with high-pile carpets, increase the suction power in the vacuum cleaner settings (Max. or Turbo). Otherwise, the robot may get stuck or miss areas.
