Owners of Xiaomi’s wireless vertical vacuum cleaners often face a sharp decline in suction power after months of active use. The main reason for this is the banal contamination of the filtration system, which is clogged with fine dust, animal hair and microparticles of debris. If you notice that your vacuum cleaner has become worse pulling or makes a whistling sound, this is a sure signal that it is time to service. HEPA-filter.
Ignoring the need for regular maintenance can cause the engine to overheat, smell bad, and even cause an expensive engine to fail. Unlike bag models, modern Mijia cyclone systems require attention not only to the garbage container, but also to a multi-stage cleaning system. Proper care of filter elements is not just hygiene, but a way to extend the life of your gadget.
In this article, we will discuss in detail the process of extracting, cleaning and drying filters for various models of vertical vacuum cleaners of the Chinese brand. You will learn why you can not use a wet filter immediately after washing, which products are strictly forbidden for washing and how often you need to carry out this procedure.
Diagnosing pollution: when to clean
Determine that the filter requires immediate intervention, you can not only visual signs, but also the behavior of the device. Many users mistakenly believe that cleaning the system is only necessary when it is visibly black, but microscopic dust particles can clog the pores. HEPA-The material long before it looks dirty.
Note the following signs indicating critical condition of the filter element:
- 📉 A noticeable drop in suction force, even if the dust container is empty.
- 🌬️ The air coming out of the exhaust hole has become warmer than usual or has a smell of dust.
- 🔊 The engine operates with increased noise or emits a characteristic whistle.
- 🔋 Reduced battery life on one charge due to increased load on the engine.
Some smart-control models, such as the Xiaomi Vacuum Cleaner G10 or G11 series, may display a clogging indicator on a display or mobile app, which is a signal that pressure sensors have detected an obstacle in the air channel, and it is also worth considering the operating conditions: if you have pets or do cleaning during repairs, you will have to clean the filter twice as often.
⚠️ Warning: If after cleaning the filter and checking the hoses for blockages, the power is not restored, the problem may lie in engine or battery failure, not in pollution.
Preparation for maintenance and necessary tools
Before starting the procedure, it is important to properly prepare the workplace and make sure that you have everything you need on hand. You do not need complex technical tools to maintain a vertical vacuum cleaner, but following the sequence of actions is critical.
For high-quality cleaning, prepare the following items:
- 💧 Flowing water at room temperature.
- 🧼 Soft liquid soap or neutral detergent (without aggressive components).
- 🧽 Soft brush with natural bristles or sponge.
- 🧻 Dry paper towels or clean rags to remove excess moisture.
It is strictly forbidden to use hot water with a temperature exceeding 40 degrees, as this can deform the structure of the filter material. HEPA-Before starting work, be sure to disconnect the vacuum cleaner from the charger and make sure it is turned off.
☑️ Preparation for cleaning
It is recommended to perform a procedure over the sink or pelvis to avoid splashing dirty water. If you plan to wash the filter, it is better to do this in advance so that by the time of the next cleaning it has time to dry completely.
Step-by-step: how to remove and clean the filter
The process of removing the filter element may vary slightly depending on the specific model of your device, whether it is Xiaomi Mi Handheld Vacuum Cleaner, Roborock H6 or newer versions of the G9 and G10. However, the overall algorithm of actions remains the same for most vertical models of the brand.
First, remove the dust collection container. To do this, press the unlock button on the case and gently pull the tank down. Inside the container, usually at the base or on the top cover (depending on the cyclone design), you will see a cylindrical or conical element, which is our filter. In some models, it is closed with a decorative cover that needs to be turned counterclockwise.
Follow the cleaning instructions:
- Carefully remove the filter from the nest by pulling a special tongue or central part.
- Shake off the main dry dust over the trash can with light tapping movements.
- Wash the filter under a jet of cold water, directing the flow from the outside inwards to wash out the stuck particles.
- If the contamination is severe, soak the element in water with the addition of a drop of mild detergent for 10-15 minutes.
- Carefully rinse the filter with clean water until the foam completely disappears.
After washing, do not twist or press the filter, as this can disrupt the integrity of the fibers. Instead, shake off the excess water slightly and leave the element to dry.

Drying and recovery time
The most critical step in the entire maintenance process is drying properly, and many users make the mistake of putting a slightly wet filter back into the device, believing that "it will dry out in the process of operation," a gross violation of operating rules that can lead to fatal consequences for electronics.
Water that gets into the engine or on the control board will cause a short circuit. So dry the filter only at room temperature in a well-ventilated room. The process can take 12 to 24 hours, depending on the humidity of the air. Do not use a hair dryer, heaters or batteries to speed up the process, as the high temperature will destroy the structure of the filter material.
Comparison of drying methods:
| Drying method | Security | Efficiency | Risks. |
|---|---|---|---|
| Natural (in the air) | Tall. | Medium (12-24 hours) | Absent. |
| Fen (cold air) | Medium | High (2-4 h) | Risk of damaging the fastenings |
| Heating appliances | Low. | Tall. | Deformation, melting |
| Direct sunlight | Low. | Medium | Fiber structure breakdown |
Make sure the filter is completely dried, not only outside, but inside the layers. If in doubt, leave it for a few more hours. Only a completely dry element can be installed back into the Xiaomi vacuum cleaner.
💡
To speed up drying without risk of damage, you can place the filter in the airflow from the fan, but do not direct the hot jet directly to the material.
Types of filters and their interchangeability
Xiaomi vertical vacuum cleaners use different types of filtration, and it is important to understand which ones are reusable and which require replacement. HEPA-filter that traps up to 99.97% of particles up to 0.3 microns in size.
Most modern models are equipped with washing HEPA-filters whose resources are approximately 6-12 However, there are also carbon filters or fine filters that can be disposable. Carefully read the labeling on the filter itself or in the instructions for your vertical vacuum cleaner model.
The main signs that it is time to replace the filter, even after cleaning:
- 👃 A persistent unpleasant smell that does not disappear after washing.
- 🌫️ Visual damage to the structure, holes or tears of the material.
- 📉 Loss of shape, deformity that prevents the filter from sitting tightly in the nest.
- 📅 Expiry of service life (usually recommended to change once a year).
The original filters can be found by the article on the body of the old element, and using non-original analogues can reduce the efficiency of air purification and reduce engine performance.
Frequent errors in the maintenance of the vacuum cleaner
Even experienced users sometimes make mistakes that shorten the life of the equipment, one of the most common is the use of aggressive chemicals, chlorine-containing products or strong solvents can corrode plastic mounts and destroy the adhesive base of the filter element.
Another mistake is incomplete assembly. After cleaning, make sure all sealing gums fall into place and the filter cover snaps to the characteristic click. A leakage disorder will cause the dirty air to bypass the filter directly into the engine.
⚠️ Warning: Never turn on a vacuum cleaner without a filter installed, this will cause instant dust to enter the engine compartment and may cause a breakdown that is not warranty repairable.
Also, do not ignore cleaning the container itself and the inlets, dust that has been collected can re-enter the clean filter when first turned on, regularly wipe the interior walls of the container with wet cloth and check the channels for large blockages.
💡
The main secret of long-term vacuum cleaner service is regularity. It is better to wash the filter in 5 minutes once a month than to change the engine after a year due to overload.
