Moving the Xiaomi Robot Vacuum charging base is often a necessity when changing furniture layouts, moving to another room or cleaning up. Many smart tech owners mistakenly believe that it is enough to simply rearrange the station and turn on the device, but navigation algorithms such as LiDAR or vSLAM require strict anchoring to coordinates. If you just move the base, the robot may lose orientation, start building a new map or, worse, will not be able to find a way home to complete the cleaning.
The correct transfer process depends on which device model you are in use. Older models with gyroscopic navigation and new flagships with a laser rangefinder respond to the change of position of the base in different ways. In this article, we will discuss the technical nuances that will avoid resetting the map and loss of saved cleaning areas, and also consider the physical requirements for the new installation site.
Features of navigation and reference to the base
The main challenge of moving a dock is how the robot remembers its location. Mijia and Roborock use the base as a reference point with coordinates (0.0). When you move the station, the robot running with the old map will look for the base in the old coordinates and will not find it, which will lead to a navigation error.
Modern models with support for Multi-floor mapping allow you to save multiple maps, but even these require the correct initialization when changing floors or radically reshuffling. If the robot can not find the base for a certain time, it can go into search mode or simply stop waiting for the user's command.
It is critical to understand the difference between camera models and laser models: Camera models, such as some versions of the Xiaomi Vacuum Mop, may be less able to navigate when lighting changes at a new point, whereas LiDAR is less sensitive to light but requires free space around the sensor.
⚠️ Warning: Never move a working robot or base during the cleaning or mapping process, guaranteed to distort the geometry of the room and create artifacts on the circuit.
Choosing the Best Place for a New Installation
Before you start moving physically, you need to make sure that the new location meets the manufacturer's specifications, and not keeping distance to obstacles is the most common reason why a robot can't dock properly with contacts or gets stuck when leaving.
The area around the base should be free from high obstacles such as chair legs, curtains or door jambs. A laser sensor located on the base body (if any) or on the robot itself should have an unobstructed view to scan the space during docking.
Also consider the availability of the socket. The use of extension cords is permissible, but not recommended, as they can create additional obstacles to the robot wheels. The flooring in the installation area should be smooth; carpets with a high pile can make it difficult for the device to enter the platform.
💡
Use paint tape to temporarily mark the free zone boundaries on the floor before the final base installation, which will help you visually assess whether there is enough room for the robot to maneuver.
Step-by-step instruction: transfer with saving the card
For models that support card saving (S5, S6, S7, S8, S10, S12 and their modifications), there is an algorithm that allows you to move the base without completely remodeling the room.
First, you need to disconnect the robot from the network and move it along with the base to a new place. It is important not to turn the device on immediately. Set the base, connect the power, put the robot on charge and only then turn it on with a button. Give the device 2-3 minutes to calibrate the sensors.
Run the app and go to the map settings. Most current firmware has a "Move Base" or "Update Base Position" feature. If that's not the case, run a short sweep around the base, drive away, scan the environment, and, knowing that the map matches but the base is shifted, suggest that it update its position or automatically adjust its coordinates.
☑️ Checklist for base transfer
If the automatic update does not occur, manual adjustment may be required, and in some cases, the system will suggest that the current position be retained as a new reference point, without erasing the previous map, but only shifting it relative to the new base coordinates.
Procedure for resetting and building a new map
In situations where the layout of the room has changed dramatically or the robot categorically refuses to accept the new base position on the old map, the only solution is to completely reset and build the map again, which is the most reliable way to avoid phantom walls and navigation errors.
First, you need to remove the card from the device's memory, and this is done through the map management menu in the app, and then the robot goes to standby mode, make sure that all the doors that should be on the map are open in the room, and the curtains are raised.
Start "Full Cleanup" or "Build a Map" mode, and the robot will start moving by scanning the room, at which point it is important not to interrupt the process or lift the device, and after the cycle is complete, the map will be saved with a new reference to the base.
| Action. | Keeping the old map | Building a new map |
|---|---|---|
| Preservation of zones and restricted areas | Retained (requires adjustments) | They need to be recreated. |
| Time of procedure | 5-10 minutes | 40-90 minutes (depending on the area) |
| Risk of navigation errors | Medium. | Minimum |
| Recommended frequency | With minor changes | During major repairs or relocation |
⚠️ Note: When building a new map, all previously created virtual walls, no-go zones and room-specific cleaning schedules will be removed.
Working with virtual walls and zones
Once the database is successfully moved and updated (or created a new one), virtual restrictions must be checked: Virtual walls and no-go zones are tied to the map coordinates, so when the base is shifted, they may end up in the wrong places, such as blocking the kitchen passageway instead of enclosing a bowl of water for pets.
In the Mi Home app, go to map editing mode. Visually compare the position of the lines drawn to the actual situation. If the map was shifted correctly, the restrictions will shift with it. If a new map was built, the lines will have to be drawn again.
Pay special attention to the No-go zones around the base, make sure that the new installation site does not get stuck between the base and the nearest furniture, and add additional rectangular exclusion zones on the sides of the charging station if necessary.
The secret to fine-tuning zones
Common Errors and How to Resolve Them
Even if you follow all the instructions, users often face problems, and one of the most common is that the robot can't see the base, which can be because it's too light at the new point (direct sunlight blinds the IR receiver) or, conversely, too dark for some optical sensors of some models.
Another mistake is to put the base on the carpet, and even a thin carpet can create enough resistance to keep the robot from snuggling tightly to the contacts, and in such cases, it is recommended to put a hard base or linoleum under the base.
If the robot is constantly losing the map after transfer, try cleaning the sensors. Clean the laser rangefinder window and the cliffsensor bottom sensors with soft dry cloth. Dust on the optics is a common cause of disorientation.
💡
The main reason the robot doesn't find the base after the transfer is because the expected and real environments don't match, so make sure that nothing has changed around the base since the last successful scan.
