Xiaomi’s modern wireless vacuum cleaners have proven to be reliable cleaners, but even the most advanced technology requires regular maintenance. Many users are faced with a situation where the device begins to suck up dust worse, emits extraneous sounds or discharges quickly. 90% of the time, the problem lies not in engine failure, but in the banal contamination of the filtration system, which simply needs to be cleaned.
Regular maintenance of the filtration system is not just a matter of hygiene, but also a way to extend the life of an expensive gadget. A dust-filled filter creates tremendous resistance to airflow, causing the engine to run at its limits, which inevitably leads to overheating and reducing battery life. In this article, we will discuss in detail the cleaning process of the main filter elements in various models of vacuum cleaners such as Xiaomi Vacuum Cleaner, Dreame and Roborock.
The cleaning procedure does not require special tools or deep technical knowledge, but has its own nuances, ignoring which can lead to damage to delicate materials. HEPA-We'll use hot water filters or aggressive chemistry, because it destroys the microstructure of the fibers. Next, we'll look at a step-by-step algorithm that will help you return the device to its factory suction power in minutes.
Diagnosis of pollution and preparation for cleaning
Before you start disassembling, you need to make sure that the problem is really filters. Modern models of smart vacuum cleaners often signal the need for maintenance through the Mi Home mobile app or voice notifications. However, visual inspection and understanding of symptoms are also important for accurate diagnosis of the condition of the device.
Note the way the engine works: if the sound is more deaf and the air stream at the outlet is weakened, this is a sure sign (blockage) of the filter system. It is also worth checking the indicators on the case or in the application, where the filter icon may be burning. Sometimes users confuse the pollution of the main cyclone unit with a clogged outlet filter, although you need to clean both elements.
To perform a quality procedure, you will need to prepare a workplace and a minimum set of tools, the best thing to do is to clean over the trash can or on the floor covered with newspapers to avoid secondary contamination of the room with rising dust.
- 🧤 Gloves (recommended to use so as not to stain your hands with fine dust and allergens)
- 🪥 Soft brush or old toothbrush (to remove dust from the surface of filters)
- 🌡️ Warm water container (only for washing reusable elements, if provided by the instructions)
- 🧻 Paper towels or napkins (for drying and cleaning internal surfaces)
Make sure the vacuum cleaner is completely off and disconnected from the charger. This is a basic electrical safety rule that can not be ignored even when working with wireless models. Removal of the battery is usually not required, since we only work with removable elements of the dust collector.
Disassembly of the dust collector and removal of filters
The process of extracting filter elements may vary slightly depending on the specific model of your device. In the Xiaomi Vacuum Cleaner 1S, 2 Pro or G9 lines, the design may have its own characteristics, but the general principle remains the same for most vertical models.
First, you need to disconnect the dust container from the main engine unit, usually pressing the corresponding lock button located at the top of the container or on the handle. After removing the container, open the upper cover to access the cyclone block.
Inside, you'll see the main cyclone separator and, often in the upper or lateral portion, the filter element itself. In some models, such as the Dreame V11 or T20, the filter can be hidden under an additional protective mesh. Carefully remove the filter by pulling a special tongue or handle, trying not to scatter the accumulated dust inside.
☑️ Disassembly procedure
It is important to remember the sequence of removal of parts, especially if you are doing it for the first time. Although the design is ergonomically thought out, accidental loss of small screws or improper installation of the mesh can lead to problems in the assembly. If the filter consists of several layers (for example, an external mesh and an internal corrugated element), separate them carefully.
Cleaning of the cyclone block and container
Before you can do the filter, you have to clear the container and the cyclone block from the large debris and fine dust, and this is where 80% of the pollution settles, and if you skip this step, cleaning the filter will be ineffective. Fine dust stuck on the walls of the cyclone, can rise again with a strong flow of air and quickly clog the clean filter.
Shake the contents of the container in the bin. To remove sticky or fine dust that has stuck to the walls of the plastic, use a dry wipe or soft brush. It is not recommended to wet the cyclone block with water unless the instructions to your Xiaomi model clearly indicate that it is completely sealed and washable.
⚠️ Warning: Never use sharp objects (knives, screwdrivers) to scrape dirt off the plastic walls of a cyclone. Scratches on plastic create roughness that will cling to even more dust in the future, making cleaning more difficult.
Pay special attention to the inlet where air enters the engine. Make sure there are no tangles of wool or hair that can block airflow. In models with cyclone separation technology, it is important to keep the inner surfaces smooth to maintain air swirls.
If you use a vacuum cleaner to clean the fur of animals, we recommend combing the roller brush beforehand, since the hair is often wound on the axle and can get inside the container when disassembling. A clean cyclone unit is the guarantee that the main filter will last longer.
Cleaning technology HEPA-filter
The most important step is cleaning the main filter element. in vacuum cleaners Xiaomi and Dreame are most often used. HEPA-filter E11 or E12, They're made of corrugated synthetic material, and they're the ones that trap the smallest particles of dust, allergens and bacteria, keeping the air out clean.
There are two main approaches to cleaning, and the choice depends on the type of filter you have: If you have a washable filter installed (usually a denser structure and often comes with the main model), it can be washed under a water jet. If the filter is paper or marked with a "Dry Only" icon, the use of water is strictly prohibited.
Use only cold or slightly warm water to wash, point the jet of water against the direction of air movement (clean to dirty) to flush the contaminants outward rather than driving them deeper into the pores, and tapping the filter handle lightly on the edge of the sink will help knock out the stuck dust.
Can I wash the filter with soap?
After washing, gently shake off the excess water. Under no circumstances squeeze the filter, twist it, or use a hair dryer or heater to speed up drying. High temperatures deform corrugated corrugated water and can melt the adhesive base, after which the filter will become useless.
Drying and care for additional elements
The drying process is a critical step in the way the vacuum cleaner can function. A wet filter installed in the device can lead to water entering the engine, causing short circuits and irreversible breakdowns. In addition, the humid environment is ideal for bacteria to multiply and produce unpleasant odors.
Leave the filter to dry in a well-ventilated room at room temperature. Avoid direct sunlight as ultraviolet light makes synthetic materials brittle. Minimum drying time is 24 hours, but for full warranty it is recommended to wait up to 48 hours, especially if the filter has been washed thoroughly.
While the main filter is drying, be sure to check and clean the safety nets, which are often covered with large villi and hair that can be easily removed with a dry brush, and wipe the inside of the container lid where the filter is attached to remove any dust.
- 🌬️ Place the filter vertically or horizontally in a place with good air circulation.
- ☀️ Avoid direct sunlight and heat sources (batteries, heaters)
- ⏳ Do not use the vacuum cleaner until all elements are completely dry (minimum 24 hours)
If you notice that after cleaning and drying the filter is left gray or black, and its structure is loose, then the material is exhausted, in which case no cleaning will return to its original properties, and you will need to replace the filter with a new original or compatible counterpart.
Assembly of the device and check of performance
Once all the elements are completely dry, you can start the assembly. Make sure that the hands and parts are free of villi from the towel or moisture residue. Collect the filter in reverse order: first install the internal corrugated element (if it was separated), then put on a protective net.
Insert the filter into the container compartment that is designed for it, it should stand tight, without gaps. If the filter dangles or, on the contrary, does not fit, check the assembly correctly and there is no deformation. The filter's loose fit will lead to dirty air leaking past it, which will negate all cleaning work.
Close the lid of the cyclone block until the characteristic click. Make sure all latches are closed. Now you can attach the container to the main vacuum cleaner unit. Turn on the device and check the suction force. The sound of the motor should be smoother and the power should be much higher.
| Element | Frequency of cleaning | Cleaning method | Time to dry |
|---|---|---|---|
| Dust container | After every cleaning. | Devastation, dry-cloth wipe | Not required |
| Protective net. | Once every 2 weeks | Dry brushing | Not required |
| HEPA-filter | Every 1-2 months | Washing with water (if washed) or brushing with a brush | 24-48 hours |
| Motor filter | Every 6 months | Only dry brushing. | Not required |
💡
For extension of service HEPA-Try not to vacuum the building dust (gypsum, cement) or water. These substances instantly clog the pores and hardly wash out.
Typical errors and expert recommendations
Despite the simplicity of the procedure, users often make mistakes that negate all efforts or even damage the device. One of the most common mistakes is to try to speed up drying with a hair dryer. Hot air deforms the thin petals of the filter, after which it stops fitting tightly to the walls, letting dirt directly into the motor.
Another common mistake is using aggressive chemistry or washing the filter in the washing machine. The mechanical effects of the drum and the chemical reagents destroy the microstructure of the filter material. The filter may look whole, but it will stop trapping fine dust, turning into a regular mesh.
⚠️ Warning: Do not turn on the vacuum cleaner unless you are 100% sure that the filter is completely dried.Even a few drops of water entering the engine turbine can cause corrosion or short circuit, which is not a guarantee.
Experts also recommend not to save on consumables: If after 3-4 cleanings the filter does not regain its color and the suction power falls, it must be replaced. Using a heavily worn filter creates excessive pressure on the engine, which can lead to its burnout, and replacing the engine costs much more than a new set of filters.
💡
Regular filter cleaning once a month allows you to save up to 30% of the suction power and prolongs the battery life by reducing the load on the engine.
Following these simple rules of care for your Xiaomi Vacuum will ensure cleanliness in the house and the durability of the device itself. Remember that smart appliances require careful attention, and timely maintenance is the best investment in its long service.
