Possession of modern smart appliances allows you to automate household processes, but sometimes there is a need for a spot cleaning of a particular area of the floor. Many users of the Smartmi and Roborock ecosystem devices are faced with the question of how to run a Xiaomi robot vacuum cleaner only in a certain area without having to clean the entire apartment, this is especially true after cooking in the kitchen or playing with pets in one of the rooms.
Local cleaning saves battery life and reduces the time of the device. Instead of a full cycle, which can take more than an hour, the gadget will complete the task in 10-15 minutes.
In this article, we will discuss in detail the software methods of activation of the mode, work with virtual walls and features of mapping in the Mi Home application. You will learn how to configure scenarios for automating the process and what nuances should be considered when planning a cleaning route.
Basics of point cleaning functionality
The fundamental basis for performing these types of tasks is that the device has a room mapping function. LDS-It's not technically possible to start cleaning only one room without a pre-stored and up-to-date map, because the robot won't know where it is relative to the target area.
When you select the "Clean Room" or "Zoning" option, the device gets the coordinates of a particular sector. The motion algorithm changes from chaotic or spiral to sequential bypassing a given perimeter. This requires high positioning accuracy, so it is important that there are no errors on the map, and the robot itself is at the base or in the zone visible to it before starting.
It's worth noting that different generations of vacuum cleaners may have different names for the same features in the interface, for example, in earlier versions of firmware it could be called "Spot cleaning", and in newer versions it could be called "Zone cleaning". Understanding how navigation works will help you navigate the menu faster, even if the manufacturer has updated the design of the application.
⚠️ Note: If the robot vacuum cleaner has lost the card or you have cleared the device’s memory, the selective cleaning function will not be available until a new detailed map of the apartment is built.
Using the Mi Home app to select a room
The most common and convenient way to manage it is the Mi Home mobile app (or Xiaomi Home), which once the map of the room is stored in the device's memory, the interface suggests dividing it into separate rooms, which allows you to start cleaning with a single touch. You don't have to draw boundaries every time, just select the desired room from the list or tap it on the diagram.
To activate the mode, open your device card in the app. On the home screen, where you display cleaning progress and battery charge, you will see the Room cleaning button. When you click, you will open a map where each zone will be signed (for example, "Kitchen", "Bedroom"). You can select one or more adjacent rooms to process.
It's important to set up the cleaning order correctly if you're choosing multiple rooms, and you can set the sequence in the scenario settings so that the robot can remove the kitchen first and then move into the hallway, and that eliminates the device moving through the cleaned areas, carrying dust.
- 🏠 Open the Mi Home app and go to vacuum cleaner management.
- 🗺️ Click on the card icon or the "Cleaning Room" button on the home screen.
- 👆 Select specific rooms by highlighting them on the scheme with your finger.
- 🚀 Click the Start button to start the process only in selected areas.
If you use voice control via AliExpress Genie or Google Assistant associated with your Mi Cloud account, you can start cleaning with a voice command, but selecting a specific room through voice is not yet supported by all language packages and requires fine-tuning scenes in the app.
Configure zones and virtual restrictions
A more flexible tool is manual zone cleaning, which allows you to set a rectangular area of any configuration right on a map, ideal for situations where you don't want to clean the whole room, but rather the space around the dining table or the area at the front door.
To create a zone, go to map editing mode or select Area Cleanup. The screen will show a frame that you can move and change sizes. You can add several of these rectangles if there is a lot of contamination in different places. The robot will sequentially move from one zone to another.
Special attention should be paid to virtual walls, which are areas where the robot is not allowed to enter, so if you want to remove the area next to a carpet that can not be wet (in wet models), or next to scattered wires, draw a no-go zone, which ensures that the navigation system will build a route around the dangerous area.
⚠️ Warning: Virtual walls and zones are stored in the robot's memory. Remember to remove time limits after cleaning, otherwise the next time the device may ignore important areas of the floor.
The accuracy of the boundary setting depends on the quality of the map. If the map has biases relative to the real walls, the robot can touch furniture, in such cases it is recommended to use physical restrictive tapes (if the model supports magnetic tapes) or simply remove small objects before starting.
💡
To quickly set up the cleaning area, use the “Copy Zone” function if you need to clean the same area regularly (for example, a place under the pet feeding table).
Spot mode: local cleaning in a spiral
There's another type of partial cleaning called "Spot," which is unlike areas where the robot moves backwards, in this mode, the device does an intensive spiral cleaning within a radius of about 1.5 meters from the launch point, which is relevant for models without building a map or for emergency cleaning of local pollution (sugar is waking up, a piece of food is falling).
You can run this mode either through the app, selecting the appropriate icon, or with buttons on the body of the device itself. Usually it is a long press on the on button or a separate key with the image of the spiral / point. The robot will make several circles, expanding and narrowing the radius to collect maximum debris at one point.
It's a good technique for simplicity, but it has limitations: Spot is not good for cleaning up stretches or corners; it's only effective in the middle of open space; and older models can work in this mode less efficiently than newer algorithms with turbo-suction mode.
If you plan to use this method often, make sure the brush doesn't get tangled.Intense rotation in one place quickly winds the hair and wool onto the shaft, which can lead to motor overload and error.
☑️ Check before starting Spot mode
Comparison of models and support of functions
Not all Xiaomi devices support the full range of zoning functions. Budget models such as the Mi Robot Vacuum Mop Essential often lack the ability to build a map and divide it into rooms, and operate on a chaotic principle or simple snake algorithm, so choosing a specific room for them is not available software.
The flagship models of the Roborock S5/S6/S7 series and Mi Robot Vacuum Mop 2 Pro have full functionality. They not only build a map, but also allow you to save several maps (relevant for cottages or multi-level apartments), adjust the suction force for each zone separately and adjust the water supply when washing the floors.
| Model of the device | Mapping | Zoning (Room) | Virtual walls | Preservation of maps |
|---|---|---|---|---|
| Mi Robot Vacuum Mop Essential | No (Gyroscope) | No. | No. | No. |
| Roborock S5 Max | Yes (LDS) | Yes. | Yes. | Yes (1 card) |
| Xiaomi Vacuum Mop 2 Pro | Yes (LDS) | Yes. | Yes. | Yes (up to 4 cards) |
| Roborock S7 MaxV | Yes (LDS + Camera) | Yes (3D) | Yes (3D) | Yes (up to 4 cards) |
When choosing a smart home device, consider having a laser rangefinder (tower at the top), which is critical to smart zoning. Camera models (vSLAM) can also build maps, but they need good lighting, which is an important condition for their work.
A key difference with premium models is the ability to adjust the cleaning sequence of rooms and individual suction power for each zone, which allows, for example, the carpet in the living room to vacuum at maximum power, and the laminate in the hallway to minimize, saving charge.
Why can't the robot see the room?
Automation and cleaning scenarios
Xiaomi's ecosystem allows you to create complex automation scenarios, so you can set the device up so that it starts cleaning the kitchen automatically when you leave the house, or it involves cleaning the hallway when you open the smart lock, and it turns the robot vacuum cleaner from just a commandeer into a full-fledged assistant.
To create a script, go to the "Automation" tab in the Mi Home app, and you can set the conditions "If it's 14:00" and "If the battery is > 50%", TR "Start cleaning: Kitchen." The logic can be anything limited to your imagination and a set of smart devices.
Integration with smart outlets is also available, for example, if you can configure a scenario where a robot only starts cleaning when the smart outlet to which the air purifier is connected shows low pollution levels (which indirectly indicates that there are no people in the room), although these are more complex schemes, they demonstrate the flexibility of the MiOT protocol.
- 🕒 Start cleaning on a schedule when you are not home.
- 🔋 Link the start to the battery level.
- 🚪 Use triggers from other devices (door opening, motion sensor).
- 📢 Get notifications on your phone immediately after your local cleaning is completed.
Remember, for automation to work, the device must be online. If you're on vacation and you turn off the router, scripts won't run. For remote control, you'd better keep the Wi-Fi network active.
💡
Automation is the best way to make the technique work for you without daily manual intervention, turning one-off actions into a familiar rhythm of life.
Typical problems and their solution
Even the most advanced algorithms sometimes fail, and a common problem is that the robot can't find a room on a map or ignores the boundaries of the zones, and this is often because the environment has changed, new furniture has been added, chairs have been rearranged, or lights have changed, and the sensors perceive this as a new obstacle and re-engineer the route.
Another common mistake is to lose communication with the base when you return from the zone. If the cleaning area is far from the dock and the battery is low, the robot may not be able to return. Always monitor the charge level before starting large areas, especially if there are rapids or carpets in the house that increase energy consumption.
If the app says "Zone Out of Reach," check if you have closed access to that part of the apartment (e.g., locked the door), and the robot will not be able to physically drive into the locked room, even if it is marked as available on the map, in which case updating the map is the only right solution.
⚠️ Warning: Never lift or carry a robot while building a map or operating in zoning mode.This knocks down the gyroscope and can lead to a loss of orientation, after which the device will start to randomly rush around the room.
Regularly update your device’s firmware through the app. Xiaomi engineers are constantly improving navigation algorithms and fixing bugs related to room and obstacle recognition. A fresh version of the software is the key to stable operation of all functions of the smart home.
