Xiaomi devices are famous for their reliability and minimalist design, but even the highest quality trimmer for clothes requires maintenance over time. If your machine has stopped effectively removing pile, emitting strange sounds or simply requires cleaning from accumulated dust, then the question arises about its internal revision. Disassembly of such a gadget is a delicate process, requiring understanding of the design and the presence of specific tools.
Unlike many household appliances, clothing trimmers often have no visible screws on the body, which confuses inexperienced users.The manufacturer uses hidden latches and screws under protective stickers to maintain tightness and aesthetic integrity. Attempting to open the device without preparation can lead to the breakdown of plastic mounts, so it is important to act consistently and carefully.
In this guide, we will look at the steps of dismantling popular models such as Xiaomi Mijia or Deerma, which are often produced in the same factories. You will learn how to safely remove the cutting unit, access the engine and replace the battery if it loses capacity.
Tools and workplace preparation required
Before you start dismantling, you need to organize the space. The work surface should be clean, well-lit and free of unnecessary objects. Small screws and plastic parts are easily lost, so immediately prepare a magnetic tray or small containers for sorting the fasteners. This will save you from a long search for lost elements in the carpet.
You'll need a standard toolkit that any home craftsman can use, with a thin cruciform screwdriver (usually a PH0 or PH00) playing the main role, and in some cases, you may need a flat screwdriver to gently snap plastic clips, but you need to be extremely careful.
- ๐ง A set of precision screwdrivers (cross and flat)
- ๐งค Thin plastic blades or a mediator to open the body
- ๐งน Soft brush and compressed air for cleaning
- ๐ง Lubrication for plastic and sewing machines (silicone)
It is important not to use metal objects to pick in the crevices of the case, as they can leave scratches or damage the internal plumes. Plastic tools (spoogers) are ideal for working with the glossy plastic of Xiaomi devices. Also remember to skim your hands or put on gloves so as not to stain the internal components.
โ๏ธ Preparation for disassembly
Algorithm of removing the protective net and the knife block
The first step is always to remove the outer safety net, which is the one that takes the brunt of the blow and protects the fabric from sharp blade damage. In most Xiaomi and Deerma models, the grid is either mounted on the thread or on the swivel lock. Carefully examine the mounting ring: if you see the notches or arrows, then the mechanism is rotary.
To remove the threaded grid, you just need to twist it counterclockwise, and if you use a pivot fixing system, you need to push the ring a little bit and turn it in the direction indicated on the body. Don't put too much effort: if the grid isn't removed, you may be turning the wrong way or the mechanism is full of pile that interferes with the movement.
โ ๏ธ Warning: Never try to remove the net by pulling it up with force. The thin metal can deform, causing the knives to touch and engine failure when assembled.
Once the net is removed, you can access the cutting unit itself, some models also have screws or plastic latches, carefully remove the blades, try not to hurt yourself against the sharp edges, and this is where most of the downflow is accumulated, which causes the mechanism to jam.
Net removal nuances
Disassembly of the main body: search for hidden screws
The hardest part is to unplug the main body, and electronics manufacturers are trying to make the devices monolithic by hiding the fasteners. In Xiaomi's reel machines, the screws are often hidden under decorative plugs, rubber legs, or stickers with technical information.
If you can't see the screws, try to warm the sticker carefully with a hair dryer (not too hot air) to soften the glue and look under it. Often, that's where the main screw is hiding, holding the halves of the body together, and also check the area around the on button and charging port.
If you don't have any visible screws, you're going to have to put the body on plastic latches, and then you're going to need a plastic blade, and you're going to start putting it in the junction between the halves of the body, and then you're going to do this circular motion, and you're going to slowly snap the clips around the perimeter, and you're going to click the characteristic snap that the latches are free.
| Type of attachment | Location. | Tool. | Risk of damage |
|---|---|---|---|
| A threaded ring | Top part (grid) | Hands/Rubber glove | Low. |
| Hidden screw | Under a sticker or stub | Thin cross screwdriver | Medium. |
| Plastic clips | Perimeter of the hull seam | Plastic spatula | High-pitched |
| Adhesive compound | The junction of halves (rarely) | Fen, blade. | Very tall. |
Slowly and methodically, a sharp jerk can break the plastic ears of the latches, and then it will be almost impossible to assemble the case back without gaps and creaks. If you feel strong resistance, stop and look for the missed screw.

Take a picture of each screw before you unscrew it, which will help you understand which screw to twist when you build it, as they may vary in length.
Access to engine and power supply
Once the body is successfully opened, you'll see the interior of the device, the electric motor that drives the knives takes center stage. Modern Xiaomi models use compact motors with high torque, which can be mounted in rubber dampers or soldered to a board.
Below or to the side of the motor is a battery, most of the time it's a standard 18650 lithium-ion cell or a flat polymer battery, connected to the control board via a connector or directly soldered wires, and if you're looking to replace the battery, it's important to find a battery with the same dimensions and voltage (usually 3.7V).
- ๐ Battery: Check the marking and capacity (mAh)
- โก Control fee: check for oxides
- โ๏ธ Motor: Check the freedom of rotation of the shaft
- ๐ Contacts: make sure the reliability of the rations
When working with electronics, be careful: Do not short the contacts of the battery with metal tools. If the battery is swelled or has damage to the insulation, its operation is prohibited - replace the element immediately.
Cleaning, lubrication and maintenance of machinery
The main reason for the trimmer's reduced efficiency is pollution: pile, dust and microparticles of tissue are stuffed between the blades and into the motor bearings. After disassembly, you need to thoroughly clean all available surfaces. Use a soft brush to remove dry debris and a cotton swab, slightly soaked in alcohol, to wipe hard-to-reach areas.
Pay special attention to the contact area of the knives. Even a microscopic layer of fat or dust can disturb the balance and cause vibration. After cleaning, be sure to lubricate the rubbing parts. The best way to do this is with a special oil for sewing machines or silicone lubricant that does not thicken over time and is safe for plastic.
โ ๏ธ Attention: Do not use WD-40 Or other penetrating lubricants to keep the machine lubricated, which can dissolve the plastic in the body and evaporate after a short time, leaving the machine dry.
Apply the lubricant in the minimum doses required. Excess oil can leak out during operation and stain the clothes you will be handling, just one drop on the axis of rotation of the knives and a drop on the motor bearings, if you have access.

Regular cleaning and lubrication of the knife unit after each active use increase the service life of the device by 2-3 times.
Assembly of the device and verification of functionality
The assembly is done in reverse order. Make sure that all the wires are stacked in their channels and do not fall under moving parts or into the compression areas of the body. When you connect the halves of the body, first snap one side, then the opposite side, moving around the perimeter. You should not hear the crunch of plastic.
Roll all the screws in, but don't tighten them all at once. First, make all the fasteners, then tighten them evenly, and this will prevent the body from skewing and slitting, install the cutting unit and the safety net, checking that they are easy to rotate or fix.
The final step is a test run. Turn on the device and listen to the sound of the motor. It should work smoothly, without any extraneous knocks, creaks or interruptions. If the vibration increased, you may have tightened the net poorly or installed the knife block incorrectly.
