Owners of Xiaomi portable appliances and Deerma sub-brand often face the need to thoroughly clean the device from fine dust, which over time clogs the filtration system and reduces the suction power. Standard washing of the garbage container is usually not enough, since the main layer of contamination settles on the turbine blades and internal walls of the duct. Understanding how to properly disassemble the Xiaomi hand vacuum cleaner allows you to extend the life of the engine and restore the original traction without going to the service center.
The dismantling process requires care and a minimal set of tools, as Chinese engineers often use hidden screws and plastic latches to give the body a monolithic effect. Incorrect disassembly can lead to breakage of mounts or damage to delicate electrical contacts. In this guide, we will take a detailed look at the steps of opening the case of popular models such as the DX700 and DX1000, paying attention to nuances that are not specified in the official documentation.
Before any manipulations, make sure that the device is completely disconnected from the charger and the battery is discharged or disconnected, if possible structurally. Safety when working with electrical appliances is the first priority, even if it is a low-voltage technique. We recommend preparing a workplace with good lighting and a soft surface, so as not to lose small parts and scratch the plastic of the case during operation.
Tools and workplace preparation
Qualitative disassembly of any gadget is impossible without the appropriate tools that will avoid damage to the case. To work with manual vacuum cleaners Xiaomi Deerma you will need a cross screwdriver of small size, often this is the format of PH0 or PH00, since the screws are miniature. Also, it will not be superfluous to have a plastic blade (spooger) or a mediator card for neat opening of latches without the risk of leaving scratches on glossy surfaces.
The organization of the workspace is critical, because there are many small screws of varying lengths inside the device. A magnetic mat or just a sheet of paper with markup will help you not confuse fasteners when you build. Some screws can be hidden under decorative stickers or rubber plugs, so prepare also tweezers and a thin blade for their careful extraction.
☑️ Disassembly tools
It is important to note that some models may have screws closed with warranty seals. Opening such seals automatically deprives the owner of the right to warranty service. If your vacuum cleaner is under warranty, it is worth weighing the risks of self-intervention, as loss of leakage or sloppy assembly can lead to failure of electronics.
Design features of the Deerma DX700 and DX1000 models
The line of hand vacuum cleaners from Deerma, part of the Xiaomi ecosystem, is based on a similar modular design, which simplifies the process of their maintenance. HEPA-Understanding how these nodes interact with each other helps to identify fastening points and access paths to the insides of the device more quickly.
The DX700 features a more compact form factor and vertical engine layout, while the DX1000 often features an improved cyclone filtration system with more complex duct geometry. The cyclone separator plays a key role in these models, creating a vortex flow that separates large dust from the air before it hits the engine.
Differences in the design of filters
Particular attention should be paid to the material of the body: mainly used impact-resistant ABS-plastic, which, however, can be brittle at low temperatures. If you are disassembling in a cold room, it is recommended to preheat the device to room temperature to reduce the risk of microcracks on plastic latches during dismantling.
Dismantling of external elements and container
The first step is to disconnect the dust collection container, which is usually fixed by the lock button at the top of the device, press the lock and smoothly pull the flask down, trying not to exert excessive effort to break the plastic guides.
Once the container is removed, you will have access to the primary filter and engine inlet, some versions of which have screws holding a decorative lining or air intake grille, carefully twist the visible screws and inspect the perimeter for hidden fasteners that can be disguised under the color of the body.
⚠️ Warning: Don't force the container torn off unless it's removed. Check if the lock is fully open and make sure there's no large debris inside blocking the flask's exit.
The next step is to remove the handle if your model is designed to detach it, often the handle contains the power button and the battery pack, and to access the insides, you need to unscrew the screws that are located at the bottom of the handle or under removable plugs, use a thin tool to plug the plugs, acting as delicately as possible.
Disassembly of engine compartment and turbine
Once you reach the engine bay, you'll encounter the main unit where the engine and turbine are located, and this is the heart of your vacuum cleaner, and it has a direct impact on performance. To remove the engine casing, you'll need to twist some screws around the perimeter. Once you remove them, split the halves of the body using a plastic blade, passing through the junction and gently opening the internal latches.
Inside, you'll see the electric motor and the turbine impeller, which tends to accumulate sticky dust and wool on its blades, and the turbine should be cleaned with a dry soft brush or compressed air, and the use of moisture in this compartment is strictly prohibited, as water entering the engine windings or control board will short circuit.
| Component | Type of pollution | Cleaning method | Frequency |
|---|---|---|---|
| Cyclone filter | Big dust, baby. | Water washing | Once a week. |
| HEPA-filter | Fine dust, allergens | Dry brushing | Once a month |
| Motor turbine | Sticky plaque, hair. | Dry cleaning | Six months |
| Air intake grid | Pooh, pile. | Tweezers removal | As pollution progresses |
When assembling the engine unit, make sure all sealing gums fall into place. A leaky duct will result in a loss of suction power, as air will be sucked through the slits, bypassing the turbine's work area. Collect the halves of the body before the snap of the latches and put all the screws back in place.
💡
Use tape or paint tape to temporarily fix removed wires or small parts so they do not get lost in the process.
Maintenance of the filtration system
Xiaomi's handheld vacuum cleaner filtration system is multi-stage, and each step requires a different approach. The primary cyclone filter you extracted in the first step can be washed under running water. However, this should be done without the use of aggressive detergents that can damage the structure of the filter material.
HEPA-The filter requires more careful handling, and although many manufacturers allow it to be washed, experts recommend limiting dry cleaning to a soft brush. HEPA-The filter must dry for at least 24 hours in a well-ventilated area, and even a slightly wet filter can cause mold to develop inside the case and cause unpleasant odors when operating.
⚠️ Warning: It is strictly forbidden to turn on the vacuum cleaner with a wet filter installed. Water can get into the engine, which will cause corrosion and failure of the device.
Regularly replacing filters is key to your vacuum cleaner's long life, and even with thorough cleaning, the filter pores become clogged with fine dust that cannot be removed mechanically, and monitor the condition of the filters and change them when there is visible damage or a persistent decrease in efficiency.
Common mistakes in disassembly and assembly
One of the most common mistakes is the loss of screws of different sizes. Vacuum cleaner designs can use screws of different lengths for different nodes. If you screw a long screw into a hole designed for short, you can damage the internal components or penetrate the housing. Always check the length of the screws before puffing.
Another common problem is that plumes and wires are damaged when the halves of the body are not neatly separated; inside the device, wires can be stretched or fixed by latches; sudden movement can cause the switch button or sensors to come off the contacts. Before fully separating the parts, carefully examine the insides for connections.
Keep in mind static electricity, which can be dangerous for electronic control boards. Although the risk is minimal, it is recommended that you touch the grounded metal object before touching the internal components to remove static charge from the body, which is especially true in winter with low humidity.
Checking the performance after assembly
After you have poured out the assembly of the device, do not rush to use it immediately to clean up large volumes of garbage.The initial start should be idle to make sure that there is no extraneous noise, vibrations or smell of burning. Normal operation of the engine is accompanied by a smooth hum without whistling or knocking.
Check the tightness of the assembly by holding your hand to the docking points of the body parts during operation, and if you feel the air flow where it should not be, then the assembly is poor quality or the seals are lost, in which case the device must be re-disassembled and the leakage eliminated.
⚠️ Warning: If sparks, smoke or a sharp smell of plastic appear, immediately disconnect the device from the network and stop operating.
Successful disassembly and cleaning allows you to return the manual vacuum cleaner Xiaomi factory suction power. Regular maintenance not only saves money on the purchase of new equipment, but also provides a better cleaning in your home. Follow the instructions, and your device will last you for many years.
