How to set up a zoning room on a robot vacuum cleaner Xiaomi

Today’s Xiaomi robot vacuum cleaners and their sub-brands like Roborock or Viomi are equipped with powerful laser sensors that allow you to build accurate digital copies of your home. However, to clean effectively, it’s not enough to just start the device — you need to set up the zoning correctly. Proper space separation allows the robot to understand where to clean and where access is strictly limited.

Many owners experience a gadget getting stuck under chairs or trying to tighten the hanging wires while ignoring real obstacles. The solution lies in software settings available through the Mi Home app or Xiaomi Home. In this article, we will detail how to create virtual walls, configure invisible zones, and divide a single map into separate rooms for more flexible management.

Virtual zoning is not just a convenient option, but a necessary element to maintain the integrity of your equipment and interior. A properly configured cleaning card extends the life of the battery and navigation system of the device, preventing idle runs and unnecessary charging cycles.

Basics of navigation and map construction

Before you start creating zones, the robot vacuum cleaner has to make an initial map of the space. LDS (Laser Distance Sensor, which scans the surrounding space within a 360-degree radius, is important that the device is operated in a calm environment during the first launch, without moving people and pets, to avoid distortion on the map.

The mapping process typically takes 15 to 40 minutes depending on the area of the apartment, and it moves around the perimeter, defining the boundaries of the walls, and then fills the interior space with a zigzag, and if you notice that there are "artifacts" or tears on the map, you'd better repeat the procedure by first clearing the floor of foreign objects.

⚠️ Warning: Do not carry the robot vacuum cleaner during the construction of the map, and do not change its starting position at the docking station. This can lead to dissynchronization of coordinates and inability to return to base.

Once the scan is complete, the map is stored in the device's memory and synchronized with the cloud, and this is the map you'll be working with when you create virtual walls and zones, and the quality of the final circuit depends on the room's light and the cleanliness of the laser rangefinder, which should be periodically wiped with soft cloth.

Invisible walls and forbidden areas

One of the most sought-after features in the Xiaomi ecosystem is the ability to draw red lines that the robot perceives as insurmountable obstacles, which is ideal for protecting areas with wires, long-pile carpets or places where a pet sleeps.

From the map management menu, select the Virtual Wall tool (often indicated by the red dotted line). Draw a line with your finger at the place where the vacuum cleaner should stop. The length of the wall can be any, and the thickness of the line on the screen does not affect the physical range of the robot sensors.

• 🚧 The forbidden zone is a red-square-painted area where the robot is strictly forbidden to enter.
• 🚫 Invisible wall – a line that the device cannot cross in either direction.
• 🔄 Zone cleaning – a dedicated rectangle that is removed first or separately from the rest of the apartment.

Using these tools, you can flexibly manage the logistics of cleaning, for example, you can leave the door open to the nursery, but draw a virtual wall around the table with the designer, so that small parts do not get into the turbobrush, which greatly reduces the risk of failure of the suction mechanism.

💡

Use virtual walls to protect the places where the water bowls for animals are, so that the robot does not accidentally splash water throughout the room during wet cleaning.

Dividing the map into separate rooms

For owners of large apartments or studio houses who want to turn into separate functional zones, the function of sharing a single space is relevant. The standard algorithm can perceive the living room and kitchen as one large room, which is inconvenient when selectively cleaning.

Select the "Separate" tool (an icon with two arrows or scissors) and draw a line of tear where the wall, doorway or arch is physically located. The system automatically numbers the resulting segments. Once separated, you can name rooms, such as "Kitchen", "Bedroom" or "Corridor".

Separation allows you to assign different cleaning modes for different rooms, for example, in the kitchen you can set maximum suction power and turn on wet wipes, and in the bedroom you can have quiet mode and only dry cleaning, which makes the process more energy efficient and quiet at the right time.

If you draw a line in the middle of an open space, the robot can still try to cross it if the floor sensors do not detect the difference in altitude, in which case the combination of separation and virtual walls is better.

Use of areas for spot and selective cleaning

Zoning is especially useful when you want to remove only a certain area, like a sugar or cat food, and instead of running a full cycle of cleaning the entire apartment, you can select a specific rectangle and send the device there, which saves battery life and time.

In the Mi Home app, go to the map tab and select Area Cleanup mode, and you'll see a frame that you can adjust its size, move it to the right place and press the start button, and the robot will arrive at the specified point and clean up inside the perimeter until it reaches the specified number of cycles.

The number of passes can be customized for each zone, 2 or 3 passes are recommended for severe pollution, and the Favorite feature is available, where you can save frequently used areas so you don't draw them all over again.

Using preserved areas is especially important for open-plan apartments where the kitchen and living room have no obvious boundaries. You can create a dining room area and start cleaning only below it after the guests are in, without raising excess dust in the rest of the house.

Problems with zone recognition and their solution

Despite advanced algorithms, sometimes the robot can ignore set limits or misdetect room boundaries, often due to dark floor surfaces that the laser sensor can perceive as a cliff or a ladder, or mirror surfaces that distort the signal.

If you notice that virtual walls are not working, check if the firmware of the device has updated. Sometimes after updating the map may reset, and all zoning settings will have to be recreated, and it is also worth checking the purity of the drop sensors and the laser rangefinder.

⚠️ Warning: Black carpets or very dark floors may be perceived by the robot as a chasm, and in such cases, using virtual walls may be ineffective, as the robot will avoid these areas without software restrictions.

Another cause of disruption is poor lighting. LDS-If you have sensors that work in the dark, the optical sensors that are often used for navigation can lose orientation.

Preservation and recovery of memory cards

Xiaomi’s current robot models allow you to save up to 4-5 cards at a time, ideal for multi-level homes or apartments where furniture is often rearranged, switching between cards is automatic when you move the base and the robot to a new floor, or manually through the app.

To save the current floor map, go to the map settings and select "Save the map." Give it a clear name, such as "1 floor" or "Dacha." When you return to this floor, just select the saved map from the list, and the robot instantly navigates through the space, considering all previously created zones and walls.

Regular maintenance of the card also includes updating it, so if you bought a new sofa or repositioned a cabinet, the old plan of the room will become irrelevant, in which case you can use the "Combine Maps" function or start building a new map from scratch, saving the old zoning settings as a backup.

💡

Saving multiple maps allows you to use one robot vacuum cleaner to clean different floors or rooms with different layouts without losing zoning settings.
