How to Manage Cleaning Places and Maps in Xiaomi Robot Vacuum Cleaners: From Customization to Fine Optimization

Xiaomi’s robot vacuum cleaners are not just automatic cleaning devices, but real smart assistants that can remember your home’s layout, avoid obstacles, and clean up on a schedule. However, many users have difficulty configuring maps of rooms — the device either “loses” rooms, misshares space, ignores virtual walls. In this article, we’ll explore all the ways to manage spaces in Xiaomi’s Mibot, Viomi, Dreame, and other models based on the Mi Home ecosystem, including hidden functions and solutions to typical problems.

From basic map settings to advanced tricks like getting a vacuum cleaner to just clean the kitchen or go around the baby cot, we covered everything. And if your robot persistently "can't see" new furniture or after moving out "forgot" the old layout, here you'll find unique methods of resetting the map without losing any other settings, and even if you're a beginner, after reading this article you can set up the cleaning as if the robot vacuum cleaner has been working for years.

1. How Xiaomi Robot Vacuum Built a Room Map: Technology and Limitations

Before you control a map, it is important to understand how it is created. Most Xiaomi models (for example, Mi Robot Vacuum-Mop 2 Pro, Viomi). V3 or DreameBot. D9) laser-based rangefinder (LDS) This sensor is rotating at speed. ~300 revolutions per minute, sending laser beams and analyzing the reflected signal. SLAM-Simultaneous Localization and Mapping – Simultaneously with the determination of its location, the robot builds a plan for the apartment.

But there are nuances:

• 🔹 Accuracy depends on lighting: in complete darkness LDS It works worse, so it is better to create the first card during the day.
• 🔹 Transparent surfaces knock down: glass tables or mirrors can distort the map as the laser passes through them.
• 🔹 Maximum area: Most models support cards up to 200-250 m2 in one zone.
• 🔹 Real-time update: If you move the sofa, the robot will update the map the next time you clean it up, but sometimes a forced rescan is required.

Models without LDS (such as the Xiaomi Mi Robot Vacuum Lite) use gyroscopes and optical sensors, making the map less accurate, and in such cases, cleaning areas can only be controlled through virtual walls or magnetic tapes, but not through editing the map in the application.

⚠️ Note: If the Xiaomi robot vacuum cleaner after updating the firmware "forgot" all the saved cards, do not rush to recreate them again. Try resetting the network settings in the Mi Home application (Device Settings section). → Network reset – sometimes it restores old data.

2.The first inclusion: how to correctly create a map of the room

How the robot builds the map on its first run will determine the accuracy of all future cleanups. Here is a step-by-step guide for models with LDS (e.g. Xiaomi Mi Robot Vacuum-Mop P):

1. Prepare the premises: 🧹 Remove small objects from the floor (wires, toys, shoes). 🚪 Close doors to rooms that do not need to be cleaned (such as the bathroom). 💡 Turn on the lights – it will improve the performance of optical sensors.
2. Run the scan: 📱 Open the Mi Home app, select your vacuum cleaner. 🔄 Press the map. → Start scanning (or just start cleaning in Full Cleaning mode). ⏳ Wait for the robot to go around the whole space, and it takes 10 to 30 minutes depending on the area.

Save the map.

• 📌 After the scan is completed, click Save the card in the application.
• 🏠 Assign the name of the floor (for example, "Apartment, 1 floor»).

If the map is curved or incomplete, don't save it! Delete and run the scan again.

• 🚫 Robot 'stuck' in narrow aisle and didn't scan room → Expand the aisles or use manual mode to scan.
• 🚫 On the map appeared “extra walls» → Check if there are mirrors or glass surfaces in the way.
• 🚫 The map split (for example, the kitchen and the hall became two separate zones) → It means that the robot couldn't connect the space. Try to run it from another point.

3. Map Editing: Dividing into Rooms, Zones and Virtual Walls

Once you've created the map, you can go into detail, divide it into rooms, select cleaning areas, add forbidden areas, and consider all the tools in the Mi Home app:

3.1 Division into rooms

This allows you to set individual cleaning settings for each room (for example, increase the suction power on the living room carpet).

1. Open the map in the app.
2. Click Edit → Add a room.
3. Round the room with your finger.
4. Assign a name (e.g., "Bedroom") and keep it.

Tip: If the robot has misdefined boundaries (e.g., combined kitchen and corridor), remove the divided room and recreate it. Sometimes it helps to force the map to be updated, transfer the vacuum cleaner to the base and press Update map.

Cleaning areas

Zones allow you to specify specific areas that you want to remove (or, conversely, skip), for example, you can only clean under the sofa or around the toilet tray.

• 📍 To add a zone: Click Add a zone on the map. Select a rectangle or a polygon. Select type: Clean or Exclude.

Delete

Virtual walls and no-go zones

If the robot is constantly driving into unwanted places (for example, to a bowl of cat food), use:

• 🚧 Virtual walls: drawn on a map as lines that the robot does not cross, suitable for time constraints (for example, during repairs).
• 🚫 No-go zones: they stand out as areas where vacuum cleaners should not go at all, useful for children's beds or aquariums.

Important: Virtual walls don't last after you reboot the robot! If you need them all the time, use magnetic tapes (sold separately) or no-go zones.

4. Advanced settings: multi-card systems and multi-storey houses

If you have multiple floors or a large apartment with isolated rooms, a single saved plan will not be enough. Xiaomi robots support multi-card systems, but there are nuances:

How to set up several cards:

1. For models with floor self-identification (e.g. Mi Robot Vacuum-Mop 2 Pro): Move the vacuum cleaner to another floor and start cleaning. The app will prompt you to save the new map. Assign a name (e.g., "2nd floor").

For models without autodetermination

Viomi V3

• Manually select Add the card in the settings.
• Run the scan on the new floor.
• Before cleaning, always choose the desired card in the application.

Important point: if the robot mixes floors, check:

• 📶 Wi-Fi Signal Strength: A Weak Signal Can Hit Location Detection.
• 🏠 Unique landmarks: each floor should have distinctive features (e.g. different furniture).
• 🔄 Update firmware: new versions often improve recognition algorithms.

⚠️ Warning: If you use the same base station on multiple floors, the robot may be confusing the cards.The solution is to buy a second station or carry the vacuum cleaner manually, selecting the card in the app before each cleaning.

5. Typical card problems and their solutions

Even after you set up the map correctly, you can have a problem, and we'll look at the most common errors and how to fix them:

5.1 Robot 'loses' card after update or crash

Symptoms: The vacuum cleaner starts cleaning from scratch, as if he sees the room for the first time.

Decisions:

• 🔄 Reboot the robot: Hold the power button for 10 seconds, then turn it on again.
• 📱 Update the Mi Home app: sometimes bugs get fixed in new versions.

5.2 The map has split or there are extra walls

This happens if the robot is unable to connect the two parts of the room (for example, due to a closed door or a weak LDS signal).

How to fix it:

• 🚪 Open all doors and start the full scan again.
• 🔦 Check if there are any clear obstacles (glass, mirrors) in the way).
• 📏 Manually combine rooms in the app: Click Edit the map. Select both parts of the same room. Click Combine.

5.3 Robot ignores virtual walls or zones

Frequent complaint: vacuum cleaner enters the restricted area, despite the settings.
