Xiaomi’s robot vacuum cleaners have long proven to be reliable cleaners, but even the most advanced technology requires regular maintenance. The main working body of the device is the main brush, which takes the brunt of dust, fine debris and, most critically, pet hair and hair. Ignoring the need for periodic cleaning of this unit can lead to serious consequences, including overheating of the engine, reduced cleaning quality and the appearance of extraneous noise during operation.
Owners often notice that the device begins to suck up dust or emits a characteristic crack, but not always associated with banal contamination of the shaft. Wrapping hair on the ends of the brush is not just a cosmetic problem, but a mechanical obstacle that creates excessive resistance to the engine. In this article, we will discuss in detail an algorithm of actions that will help you quickly and safely bring the cleaning module in order, extending the life of your gadget.
The maintenance procedure takes only a few minutes, but it must be performed at a certain frequency, depending on the intensity of use and the presence of animals in the house. Proper care of the main turbobrush ensures that the robot will work normally, and the cleaning map will not be lost due to the device being stuck on the carpets. Let's look at the necessary tools and preparatory steps before work begins.
Signs of pollution and the need for cleaning
There are a few obvious signs that you can tell when it's time to maintain a cleaning module that are pretty hard to ignore. First of all, you can look at the sound of the work: if the usual buzzing has changed to a strained hum or a periodic crack, this is a sure signal that the shaft is hard to rotate. The brush motor is working at increased revs, trying to overcome the resistance of the wound hair, which in the long run leads to premature wear.
The second important indicator is cleaning quality. If you notice that the robot is driving around the site but leaves visible strips of dust or scraps of wool, then the brush pile is clogged and no longer effectively knocking debris out of the coating. In addition, an error indicator may light up in the Mi Home app or on the device body, reporting a problem with the main brush.
⚠️ Warning: If the robot vacuum cleaner makes a loud grinding sound or stops completely with a message of error in the main brush, immediately stop cleaning. Continuing to work in this mode can lead to combustion of the drive belt or breakage of gear gears gear gear gears gear gear gear gears gear gear gear gear gear gear gears reduce.
It's also worth visually inspecting the end of the brush, even if there are no obvious errors. Often the hair is wound tightly at the bearing itself, where light does not penetrate, creating a "congestion". Regular inspection, at least once a week, will avoid the major cleaning that will have to be carried out if the debris compresses and hardens.
Tools and training required
Before you start dismantling and cleaning, you need to prepare a workplace and a minimum set of tools, you don't need a complex professional tool, you will find everything you need in every house, the main requirement is to provide good lighting, because small debris and dark hair can be poorly visible in dim light.
For high-quality cleaning, you will need:
- 🔪 Special brush cleaning knife (usually included) or stationery knife.
- ✂️ Manicure scissors or small tweezers to remove small villi.
- 🧹 Dry soft brush or microfiber cloth for cleaning the body.
- 🧴 Alcohol wipes or isopropyl alcohol for degreasing (optional).
It is important to make sure that cutting tools are sharp enough to cut a dense tangle of hair easily, but you must act carefully so as not to damage the plastic elements of the brush itself or rubber seals.Using blunt objects can cause you to tear your hair rather than cut it, making it harder to remove it.
💡
Use curved nail scissors - they are most convenient to poke and cut the hair wound close to the plastic stubs on the ends of the brush, without scratching the plastic.
Algorithm for removing the main brush
The process of removing the cleaning module from Xiaomi, Roborock and Viomi models is standardized and requires no force. The first step is to turn the robot vacuum cleaner upwards, make sure the device is turned off or paused to avoid accidental start of the engines during manipulation.
On the bottom panel, you'll see a protective cover covering the main brush compartment, which is fixed by two latches, which often have a characteristic yellow or orange color for easy identification. Press the locks at the same time or in turn (depending on the model) and tilt the lid to the side, after which the brush will be available for removal.
Grab the handle of the brush (usually gray or green) and pull it up. In some models, such as the Xiaomi Vacuum Mop 2 Pro, the brush can sit tight, but take it out without jerking. If it doesn't lend itself, check if a large object blocking the exit is stuck.

Step-by-step instructions for cleaning the shaft
The most time-consuming step is removing the coiled hair and wool. Most of the debris always accumulates on the ends where the shaft enters the bearings. Take a knife or a special blade and make a longitudinal incision along the wound hair, trying not to touch the plastic elements of the structure. Deep incision will allow you to divide the tight tourniquet into two parts.
After the incision, you can pull the edge of a bunch of hair and pull it out. Often, the hair is not only wound on the shaft itself, but also penetrates the end caps. In this case, you may need to remove the plugs. Many Xiaomi models have removable ones: gently apply them with a knife or screwdriver and remove them to clean the space inside.
Use tweezers or brushes to remove dust and small villi from the recesses. Wash the shaft with a dry cloth. If the brush has a greasy coating (as happens when cleaning the kitchen), you can slightly moisten the fabric with water, but the brush itself must dry completely before installation.
⚠️ Note: It is strictly forbidden to use water for washing your brush, unless the instructions for your specific Xiaomi model state otherwise.
Pay special attention to side brushes if your robot model suggests they are, and they also require cleaning hair that winds around their spin axis, and the mechanism for cleaning them is similar: removing, removing the winding, and putting it back before clicking.

Maintenance of side brushes and wheels
Although the focus is usually on the central turbobrush, the side elements also play a critical role as a cleaning service: They drive debris from under the boards and from corners under the main brush. If the side brush is clogged, the robot will throw garbage away, rather than collect it. Take it off by pulling it upwards (it holds on a slate joint), and remove all the wound hair from the axis.
And remember to check the wheels of the robot. Often, it's the long hair that winds around the wheel that blocks the wheel from spinning, causing the robot to dance in place or to map the room incorrectly. Scrolling each wheel by hand, it should rotate freely and with a slight springy force.
To clean the wheels, use tweezers or a thin screwdriver to pull the hair out of the gap between the wheel and the body. In difficult cases, the wheel can be carefully removed by pulling up with effort, but this requires more care not to damage the contacts of the sensors.
Comparison of pollution types and methods of their elimination is presented in the table below:
| Type of pollution | Localization | Deleting method | Tool. |
|---|---|---|---|
| Long hair. | The ends of the shaft | Cutting and pulling | Knife, blade. |
| Animal fur | Worth brushes | Combing | Crest, brush. |
| Fine dust | Bearings | Purge | Air cylinder |
| Filaments and filaments | sidebrush axis | Tweezers unwinding | Tweezers, needle. |
Assembly and performance check
Once all the elements are cleaned, you need to properly assemble the device. Make sure the brush is completely dry. Insert it into the seat, orienting it according to the shape of the shaft (it has a specific geometry and will stand only on one side). The handle should look in the direction indicated on the inside of the cover (usually there is a pictogram).
Close the protective cover until you click it. Turn the robot over and turn it on. Run the cleaning mode for a short time to make sure there is no extraneous noise. If the robot is quiet and even, the procedure was successful.
💡
Regular brush cleaning every 1-2 weeks increases the life of the engine to 3-4 years and maintains high suction power throughout the entire period of operation.
If you still hear a strange sound after assembly, check if the brush is standing right. Sometimes it can be skewed. Remove it and reset it, making sure that the ends of the shaft freely enter the sockets of the bearings.
