How to set up rooms in Mi Home for robot vacuum cleaner Xiaomi Mijia: a complete guide with maps and life hacks

Xiaomi Mijia Robot Vacuum Cleaners (including Models) 1C, 1T, S10 And Pros are not only able to clean floors, but also to remember the layout of the apartment, dividing it into areas for spot cleaning. However, many users face problems: the Mi Home app does not save rooms, the vacuum cleaner confuses borders or ignores virtual walls. In this article, we will discuss how to properly configure the division into rooms - from creating a map to fine-tuning the cleaning parameters for each zone.

The peculiarity of vacuum cleaners Mijia is that they use a laser rangefinder (LDS) And this is not only to avoid obstacles, but also to keep the layout precise, with the room attached, but without the right setup, even the most advanced model will clean up randomly:

• 🗺️ Create and edit a map of the apartment in Mi Home for the first time;
• 🚪 Divide the space into rooms taking into account doorways and partitions;
• 🔄 Set up automatic zone recognition after firmware update;
• ⚡ Optimize cleaning routes to save battery power.

Important: the instruction is relevant for vacuum cleaners Xiaomi Mijia with support for cartography (series) 1T/1C/Pro/S10/S12 If your model is not building a map (e.g. Mi Robot Vacuum) 1), Room division will not be available.

1. Preparation for setup: what to do before creating a map

Before you start dividing the apartment into zones, make sure that the vacuum cleaner is properly prepared for the construction of the map. Mistakes at this stage will lead to distortion of the layout or the inability to save the rooms.

First, check the firmware version in the Mi Home app: Device Profile → Settings → Update firmware. For stable operation of mapping requires a version at least lower 3.5.8_0036 (model 1C/1T) or 4.6.0_0012 (for S10/Pro). If an update is available, install it before setting up.

Second, prepare the room:

• 🧹 Remove small objects (wires, toys, shoes) that may interfere with scanning from the floor;
• 🚪 Open all interior doors – vacuum cleaner should move freely between rooms;
• 💡 Provide good lighting (laser rangefinder works worse in the dark);
• 🪑 Move furniture with transparent legs (glass tables, chairs) – they can “disappear” for sensors.

⚠️ Warning: If you have mirrors or glossy surfaces (such as wardrobes), cover them with a cloth while scanning. Laser beam reflections distort the map, causing rooms to merge or split.

Also make sure the vacuum cleaner is fully charged (at least 80%), the mapping process takes 15-40 minutes and consumes up to 30% of the battery, and if the charge is critically low, the device may interrupt the scan and not save the results.

💡

If the vacuum cleaner has previously built a map, but it is distorted, reset it before a new setting: Device settings → Map. → Clean the map. This will help avoid overlaying old data on new ones.

2. Building an apartment map: a step-by-step process

Now, to the most important step, which is mapping, the algorithm is the same for all Mijia models. LDS-sensor, but there are nuances for vacuum cleaners with multicards (support for several floors).

Step 1: Put the vacuum cleaner in the charging station in the middle of the apartment, which will help the device scan all the rooms evenly, and if the station is in the corner, the distortion of perspective will begin to prevail.

Step 2.In the Mi Home app, select your vacuum cleaner and click Map → Start cleaning. Set up Full cleaning (not zone!) mode, which will force the robot to go around all available spaces.

Step 3: Follow the process in real time:

• 📱 The screen will display a blue line - this is the route of the vacuum cleaner;
• 🏠 As the movement will appear gray contours of the walls;
• ⏳ A full scan takes from 20 minutes (for a 1-bedroom apartment) to 1 hour (for a 4-bedroom apartment).

Don't interrupt the process, even if it seems that the vacuum cleaner is stuck in one place. The scanning algorithm involves repeatedly passing the same areas to clarify the boundaries.

Make sure that the doors are not blocked by the doorsteps.|

Restart the scan if the vacuum cleaner has forgotten the room|

3. Division into rooms: tools and techniques

Once the map is ready, we start to divide into zones, and there are two tools in the Mi Home app for this:

1. Manual separation – you draw the boundaries of the rooms yourself;
2. Auto-separation – The algorithm offers options based on the detected doorways.

Method 1: Auto-separation (recommended for beginners)

Press the map. → Edit → Auto-separation. The app will analyze the layout and suggest options:

• ✅ Reaffirming the right boundaries;
• ❌ Remove unnecessary dividing lines (for example, if the algorithm mistook a large cabinet for a wall);
• 📝 Rename the rooms (living room, kitchen, bedroom, etc.).

Method 2: Manual separation (for complex layouts)

If the auto-separation fails (e.g., in a wallless studio), use the Add Wall tool:

1. Press Edit. → Add a wall;
2. Draw a line along the boundary of the room (for example, from the corner to the doorway);
3. Repeat for all zones.

⚠️ Warning: Do not draw walls directly over doorways, this will block the passage of the vacuum cleaner. Leave a gap of 10-15 cm or use the Virtual Wall function for time restrictions.

For Mijia models S10/Pro Multicards are available, which is a function of saving individual maps for each floor, to add a new floor:

1. Press the map. → Add a map;
2. Move the vacuum cleaner to another floor and start the scan;
3. After you build the map, give it a name (for example, "2nd floor").

4. Set up cleaning options for each room

Once you've split into zones, you can set up customized cleaning settings for each room, which is useful if you:

• 🧽 You need to clean the kitchen more often (daily);
• 🛋️ In the bedroom is enough to clean 2 times a week;
• 🚿 In the bathroom requires increased suction force.

How to set up:

1. Open the map in Mi Home;
2. Press the right room. → Settings of the room;
3. Select the following options: Cleaning mode: standard, intensive, quiet; Frequency: daily, on schedule, on request; Suction strength: weak (for carpets), medium, strong (for hard floors); Cleaning order: you can set a sequence of rooms.

For Mijia models 1T/1C You can use the "Site Cleaning Scheduled" feature, for example, you can configure it:

• 🕘 Cleaning the kitchen and corridor every day at 9:00;
• 🕒 Bedroom cleaning on Mondays and Thursdays at 14:00.

⚠️ Attention: If you have long-pile carpets in the room, increase the suction force to the maximum and turn on the option of Carpet Cleaning in the settings. Otherwise, the vacuum cleaner will "get stuck" or miss areas.

5. Virtual Walls and No-Go Zones: How to Limit Access

Even with properly configured rooms, sometimes you have to stop the vacuum cleaner from entering certain areas.

• 🐕 Pet feeding place;
• 🪴 Pots with flowers on the floor;
• 🎮 The area with the wires from the game console.

For this purpose, Mi Home has two tools:

1. Virtual Walls – Temporary or Permanent Barriers
2. No-go zones are areas that the vacuum cleaner will bypass.

How to add a virtual wall:

1. Open the map. → Edit → Add a virtual wall;
2. Draw the line in the right place (for example, in front of the door to the nursery);
3. Select type: Constant – is always valid; Scheduled – works at specified hours (for example, at night).

How to add a no-go zone:

1. Press Edit. → Add a no-go zone;
2. Circle the desired area (for example, around the chair with wheels);
3. Save the changes.

Important: Virtual walls and no-go zones are not saved when you reset your map or update your firmware, and you need to reconfigure them after that.

💡

For Mijia models S10/Pro Invisible walls are available, which block the vacuum cleaner's passage, but they don't show up on the map, and this is useful if you don't want to clutter the interface with unnecessary lines.

6.Typical errors and how to fix them

Even if you follow the instructions accurately, users face problems, and let's look at the most common ones and how to solve them.

Problem 1: The vacuum cleaner does not save the rooms after the reboot.

Decision:

• Update the firmware and Mi Home app to the latest version.
• Make sure the vacuum cleaner is connected to a 2.4 GHz network (5 GHz is not supported)
• Reconnect the device to your account: Device settings → Untie. → Reconnect.

Problem 2: The rooms are superimposed on top of each other.

Decision:

• Remove the current card and rescan the apartment;
• When manually split, use the option to tie to the wall so that the boundaries coincide with the real partitions;
• Check if there are mirrors or glass surfaces that distort the laser.

Problem 3: The vacuum cleaner ignores virtual walls.

Decision:

• Make sure the wall is activated (the room settings should have a green light).
• Move the vacuum cleaner base closer to the problem area – sometimes a weak Wi-Fi signal knocks down coordinates;
• For models 1C/1T Reboot the vacuum cleaner by holding the Home button 10 seconds.

7. Cleaning Optimization: Tips for Advanced Users

When the basic setup is complete, cleaning efficiency can be improved with additional features.

Tip 1: Use "room cleaning" instead of full.

Instead of sending vacuum cleaners to clean, choose only the rooms that need cleaning, which saves up to 40% of battery life and reduces cleaning time.

• 🍳 After breakfast, only the kitchen;
• 👟 After the street - a corridor and an entrance hall;
• 🛏️ Before bed - bedroom.

Advice 2: Set up a “Double Passage” for contaminated areas.

In the room settings, enable Double Pass for high-traffic areas (corridor, kitchen) and the vacuum cleaner will walk through them twice, which increases the quality of cleaning by 30-40%.

Tip 3: Synchronize cleaning with a wet cloth.

For models with wet cleaning function (Mijia) 1T/1C/S10) set up automatic floor cleaning after dry cleaning:

1. In the room settings, select Cleaning Mode → Wet cleaning;
2. Set the level of moisture (low / medium / high);
3. Set a schedule to vacuum first and then wipe.

Tip 4: Use a voice assistant to control.

If the vacuum cleaner is integrated with Alice or Google Assistant, you can start the cleaning with your voice.

• "Alice, start cleaning the kitchen."
• "OK Google, vacuum the living room."
• "Alice, get the vacuum cleaner back on base."

💡

For Mijia models S12/S15 The function "Multiple Level Cards" is available - the vacuum cleaner can remember up to 4 Automatically switch between floors when moving to another level.
