The Xiaomi Mi Vacuum Cleaner 1C wireless vacuum cleaners require periodic maintenance, especially if there are pets or long hair in the house. The main unit that undergoes maximum mechanical stress is the turbobrush as part of the main nozzle. Over time, threads, wool and dust accumulate on the shaft, which leads to reduced suction efficiency and overheating of the engine.
Many users are wondering how to properly dismantle this element without damaging the plastic latches or the electric motor itself. The design of the Xiaomi 1C roller has specific fixing elements that differ from the V10 or G9 models. The wrong approach to disassembly can cause mounts to break, after which it will be extremely difficult to restore the tightness of the unit.
In this article, we will take a closer look at the brush extraction process, look at the tools you need, and look at the nuances that are rarely mentioned in official manuals, learn how to distinguish between a regular lock and a foreign object stuck, and understand how to extend the life of your device.
Design features of the nozzle Xiaomi 1C
The Mijia Electric Floor Brush main nozzle, which comes with the 1C, is designed to minimize the number of visible screws, and it's designed to be aesthetically appealing and to protect the interior from moisture, and it's got an electric motor inside it that spins a soft roller, and a rigid turbo brush with bristles for carpeting.
Removing the brush involves working with a turbocharger, because a soft roller for hard floors is usually simply removed for washing without disassembly of the body. The turbobrush fixing mechanism is based on two sliding bearings closed with plastic covers, these covers are held in place with screws and plastic pins, which are easily damaged if handled carelessly.
It's important to understand that there are no complex electronic boards inside the nozzle that require grounding, but there are movable mechanical parts there. The gear transfers the rotation from the motor to the shaft, and any displacement of the elements can cause extraneous noise or vibration.
Tools and workplace preparation required
Before the procedure, you need to provide a clean, well-lit space, you need a flat surface, where you don't lose any small details, and you need to use a table with a white or light countertop, so that the contrasting details are clearly visible.
To remove the brush from the vacuum cleaner Xiaomi 1C will require a minimum set of tools. In most cases, one cross screwdriver is enough, but its size must be exactly the size of the screw cap, so as not to break the slime. Use too large or small bits is unacceptable.
⚠️ Warning: Never try to tamper with plastic covers with a knife or metal ruler.The sharp edge of the metal will leave deep scratches on the body and can crack brittle plastic when pressed, which will break the tightness.
List of required equipment:
- 🔧 Cross screwdriver (usually size) PH1 or PH0).
- 🔪 Office knife or scalpel (for gently cutting the wound threads before disassembly).
- 🧤 Latex gloves (to protect your hands from dust and allergens).
- 🔦 Lantern (to inspect the internal cavities for debris).
Step-by-step: how to remove the brush
The dismantling process begins with a visual inspection of the bottom of the nozzle, and flip the device over and examine the ends of the rotating shaft carefully, and you'll see two plastic caps that cover the bearings, and that's where the brush axis passes.
On one end (most often left, if you look at the brush from the bottom) is a locking screw. It can be hidden under a decorative stub or sticker, but in the 1C model it is usually open. Carefully twist this screw counterclockwise. Don't put too much effort, the threads are small.
☑️ Ready to disassemble
Once the screw is removed, the side cover may be sitting tight due to accumulated dirt or static electricity, use a plastic card or a special opening tool to fit the lid around the perimeter, and the movements should be smooth, without jerking.
When the lid is removed, you can access the shaft. The Xiaomi 1C brush has a lock pin or groove that holds it in position. In some versions, after removing the sidewall, you can simply pull the shaft outwards. In other cases, you will need to slightly twist the brush to match the grooves with the guides.
Typical problems in the extraction of shaft
Often, users are faced with a situation where the shaft does not come out even after the screw is unscrewed, because the hair and thread are wound not only on the bristles themselves, but also on the axis of the bearings, creating a dense cocoon, which acts like a wedge, blocking movement.
In this case, you can't use force to try to knock out the shaft. You need to use a thin tool, like tweezers or a needle, to carefully untangle or cut the fibers at the very base of the shaft, and only after the axis is freed from external blockages, the mechanism will start to move.
Another common problem is the jamming due to the hit of solid objects (pebbles, LEGO, buttons) inside the body. If you hear crackling when you swipe with your hand, then the foreign body interferes with rotation.
⚠️ Warning: If the shaft is stuck dead, do not try to twist it with passages behind the plastic end. The plastic will crumble, and it will be impossible to restore the integrity of the mount without replacing the part.
To solve the problem with a stuck object, it may be necessary to completely remove the second side cover or even disassemble the main body of the nozzle, which requires unscrewing the screws on the top of the device.
Cleaning and maintenance of the turbobrush
After successfully removing the brush from the body of the Xiaomi 1C nozzle, it is necessary to thoroughly clean it. Using water to wash the brush with bearings is not recommended unless you are sure of the seals' complete tightness.
Take a scissor or a special blade (often comes with a vacuum cleaner) and cut all the wound hair along the length of the shaft. Then use a comb or a hard brush to comb fine dust from the pile. Pay special attention to the ends of the shaft where the gears are located.
