How to make a virtual wall for a robot vacuum cleaner Xiaomi in the Mi Home app: the complete guide

Xiaomi’s robot vacuum cleaners have long been indispensable cleaning tools, but even the smartest models sometimes need manual control. One of the most popular features is virtual walls that allow you to limit cleaning areas without physical barriers. For example, you can block access to a crib, aquarium or wired area without buying additional beacons.

In this article, we will discuss how to create virtual walls through the official Mi Home app (including the new version of Mi Home Lite), which robot models support this feature, and how to avoid typical configuration errors. LDS-And if your vacuum cleaner is stubbornly ignoring virtual boundaries, here's the solution.

What Xiaomi Robot Vacuums Support Virtual Walls

Not all Xiaomi models are capable of working with virtual walls, and this feature is only available for devices with a map navigation system (laser or visual).

• 🔹 Laser models (c) LDS-Xiaomi Mi Robot Vacuum-Mop 2 Pro, Xiaomi Mi Robot Vacuum-Mop P, Xiaomi Mi Robot Vacuum-Mop 2 Lite, Dreame D9, Viomi V3 etc.
• 🔹 Visual models (with camera): Xiaomi Mi Robot Vacuum-Mop 2 Ultra, DreameBot X30 Ultra.
• 🔹 Budget models without mapping (for example, Xiaomi Mi Robot Vacuum) 1S Mi Robot Vacuum-Mop Essential – does not support virtual walls in the application.

If your model is not included in the list, check its specifications on the official website or in documents. For budget vacuum cleaners without mapping, physical beacons (for example, Xiaomi Mi Virtual Wall Barrier) will be an alternative, but they require additional costs.

Preparation: What to do before creating a virtual wall

Before drawing boundaries in the app, make sure your vacuum cleaner is ready for this:

1. Update the robot firmware to the latest version. Outdated software may not support virtual walls or work with errors. Check the version in Mi Home → Device → Settings → Update firmware.
2. Build a complete map of the room. Virtual walls are created on top of an existing map. If cleaning took place in only one room, the vacuum cleaner may not see other areas.
3. Connect the robot to stable Wi-Fi, and if the signal is weak, the card changes may not persist.

If the room map is missing or is built incorrectly, perform a full cleaning in Map mode (usually activated by a button on the case or through the application). LDS It'll take 10-15 minutes.

💡

If the robot loses the card after turning it off, check the Saving the card settings in the app. Some models have this option disabled by default.

Step-by-step: how to create a virtual wall in Mi Home

Consider the process using the example of Mi Home (relevant to versions 6.x and later). the interface may differ slightly depending on the model of the vacuum cleaner.

1. Open the Mi Home app and select your robot vacuum cleaner.

Ready.

Save.

Once saved, the wall will appear on the map as a transparent red line (or blue, depending on the firmware), the robot will bypass it during cleaning, and if the line does not appear, restart the application or robot.

Common Mistakes and How to Fix Them

Even if you set up the virtual walls properly, these are the most common problems and solutions.

If the problem persists, try resetting the map to factory settings (in Mi Home → Map → Reset the map) and building it again, which helps 80% of the time.

Alternative ways to limit the cleaning area

If virtual walls are not suitable (for example, for models without mapping), consider these options:

• 📶 Physical beacons: Xiaomi Mi Virtual Wall Barrier creates an invisible barrier up to 2 meters away.
• 🧲 Magnetic tape: Magnetic field tape (e.g. for iRobot robots) can block some Xiaomi models, but the efficiency depends on sensors.
• 🚪 Closed doors: The safest way is to simply lock the room. Xiaomi robots won't open the doors.
• 📱 Scheduled cleaning zones: In Mi Home, you can only order cleaning in selected rooms (if the map is divided into zones).

For Yandex-enabled Alice or Google Assistant models, voice commands like “Start cleaning the living room” can be used to limit the wall-free area.

💡

The Xiaomi Mi Virtual Wall Barrier physical beacons are suitable for all models of robot vacuum cleaners, including budget ones without mapping. Their main disadvantage is a limited range (up to 2 m) and the need to purchase (from 1,500). ₽ piecewise).

Tips for Optimal Placement of Virtual Walls

To make the walls work effectively, consider these recommendations:

• 📏 Leaving the furniture: Do not draw a wall close to the legs of the table or sofa. Leave a reserve of 10-15 cm so that the robot does not hit obstacles.
• 🚪 Passages and doors: If the wall blocks the doorway, the robot can get stuck at the doorstep.
• 🔋 Charging areas: Do not block the path from base to outlet - otherwise the vacuum cleaner will not be able to return to recharging.
• 🐕 Pets: For food bowls or trays, draw a wall with stock as the robot can "pierce" close to the border.

Check the location of the walls after the first cleaning, and if the robot still enters the restricted area, adjust the boundaries or add an additional line.

💡

For models with Mopping (wet cleaning) function, virtual walls can be used to limit areas where flooring is not allowed (such as carpets).

Frequent questions about virtual walls for robots Xiaomi

If your question is not covered in the article, check the official documentation for the model or contact Xiaomi in support through the Mi Home app (Feedback section).

💡

Virtual walls are the most flexible way to control cleaning areas, but their effectiveness depends on the quality of the map and the relevance of the firmware. Regularly update the robot software and rebuild the map when changing the layout of the room.
