Owners of modern automatic cleaning devices often face the need to re-build the route after each reset or move the base. Xiaomi Dreame F9 model has advanced navigation functionality, but it requires the correct initial memory setting. Save the map is a critical step that allows the device to effectively plan routes and clean zones, not chaotic.
The process of building a stable memory of a room depends on a variety of factors, ranging from the quality of the Wi-Fi connection to preparing the floor before launch. If you want your robot vacuum cleaner to stop wandering and start working at maximum efficiency, you need to strictly adhere to the primary scan algorithm. Ignoring the basic rules often leads to the device losing orientation or creating several disparate maps instead of one single one.
In this guide, we will take a look at all the details of working with the Dreame F9 navigation system, learn how to run the first scan correctly, how to record the result in the application and what to do if the map disappears or deforms.
Preparation of the room before the first scan
Before you start the process of building a map, you need to ensure the ideal conditions for the laser rangefinder (LDS), the robot should move freely throughout the area that you plan to store in memory, remove from the floor any foreign objects that may interfere with movement or confuse sensors, such as wires, toys or clothing.
Special attention should be paid to the thresholds and transitions between rooms. If there are high thresholds in the apartment, it is better to temporarily close them with special ramps or simply open the doors so that the navigation system considers the space as a whole, the closed doors of the rooms that you plan to clean must be open, otherwise the robot will perceive them as walls.
⚠️ Warning: Don't run the first map construction in total darkness. though the Dreame model F9 equipped with sensors, insufficient lighting can adversely affect the operation of optical sensors used to supplement terrain data.
Make sure the charging station is installed correctly. It should be against the wall, there should be at least half a meter of free space around it on the sides and two meters in front. If the base is moved after the map is created, the saved route will become irrelevant and the device may lose the point of return.
☑️ Preparation for scanning
The process of initial map construction
Starting the first scan is the most important thing. First, make sure that the robot is connected to the Wi-Fi network via the Mi Home or Dreame Home app. In the device management menu, you need to find the “Map” or “Maps Settings” mode and select the option “Restore the card” or “New card” if previous data has been deleted.
Once it's launched, it's going to start moving around the perimeter of the room, and at that point, the laser sensor is actively scanning the obstacles and the walls, and you can't stop this process, and if the device stops or is held up, the process can be disrupted, and the map will have to be rebuilt.
💡
You're in the same room as the robot during the first scan, but don't interfere with it, so you can monitor the process and see if the device gets stuck.
The duration of the process depends on the area of the room. For a standard two-bedroom apartment, it can take from 15 to 30 minutes. The robot can return to the base several times to recharge if there is not enough energy for a full cycle, but in mapping mode it usually tries to complete the scan in one pass.
| Parameter | Recommended value | Impact on the map |
|---|---|---|
| Battery charge | More than 60% | Ensures the completion of the cycle without returning to the base |
| Wi-Fi signal | Stable, 2.4 GHz | Provides data transmission in real time |
| Lighting | Daytime or bright artificial | Helps optical sensors work properly |
| Room doors | Open open. | Allows you to create a single map of the apartment |
Save and edit the map in the annex
Once the robot has completed the detour and returned to base, the map is automatically stored in the device’s memory and synced with the cloud. However, to fully use the functionality of the Xiaomi Dreame F9, the map often needs to be edited. In the application, go to the map settings, where you will see the created scheme of your home.
The first step is usually to split or merge rooms. If the robot mistakenly combined the kitchen and living room into one room, use the Split tool to draw the demarcation line. Conversely, if the corridor is divided into parts, use the Merge tool, which is necessary for proper zonal cleaning.
Next, rename the rooms according to their actual purpose. It's not just a cosmetic procedure: the names of the rooms are used in voice control and smart home scenarios. You can choose Bedroom, Kitchen, Bathroom and other standard options.
Configuring virtual walls and forbidden areas
One of the key features of the Dreame F9 is the virtual constraints. Unlike the physical magnetic tapes that were used in older models, everything is customized software. From the map menu, select the Virtual Wall or the Forbidden Zone tool.
Virtual Walls are lines that a robot cannot cross, ideal for restricting access to a wire, staircase, or doorway that must remain closed to the janitor. No-Go Zones are rectangular areas that a robot should not go into at all, such as a flower stand or a cat tray.
⚠️ Warning: Virtual walls are tied to map coordinates, and if you move the charging station or change the furniture layout a lot, old restrictions may be out of place and require adjustments.
To set the exact boundaries, zoom the map in the app to the maximum. The accuracy of the lines directly affects the efficiency of cleaning. Don't make the restricted areas larger than necessary so as not to reduce the useful area of cleaning.
Problems with card loss and their solution
Sometimes users are faced with a situation where the robot “forgets” the map or creates a new one instead of using the existing one, most often because the base has been moved even a few centimeters. For the Dreame F9, the position of the base is the reference point.
Another cause could be contamination of the laser rangefinder (LDS). If dust accumulates on the turret lid, the robot may not correctly read the distance to the walls, leading to desynchronization with the stored map. Regularly wipe the sensors with soft dry cloth.
What to do if the card is constantly reset?
There can also be problems with a weak Wi-Fi signal, so if the signal goes missing in the back room, the robot can lose communication with the server where the card is stored and start building a new one.
Multi-maps and work with several floors
Xiaomi Dreame F9 supports saving up to 4 cards (depending on the firmware version and region), which allows you to use a single robot for cleaning on different floors of the house or in a complex apartment with a complex layout, where the rooms are isolated.
To save the second-floor map, move the base to a new floor, connect the robot to the network (wait for the connection), and run the full scan again. The system will suggest saving the current map as new. It is important to give the maps clear names, such as "1 floor" and "2 floor", so as not to get confused.
When moving a robot between floors manually (e.g., on the hands), navigation can temporarily become disoriented until it recognizes the environment from a laser scanner. Give it a few seconds to "think" of the space before starting the cleaning.
💡
The robot vacuum cleaner retains its anchorage to the base. Moving the charging station without re-scanning or manual adjustment in the application will result in the lost relevance of the saved card.
