Regular maintenance of home appliances is the key to its long and efficient operation. Owners of smart devices from Xiaomi often face the question: how to properly care for the filter system, so as not to lose the warranty and maintain high suction power? Dust, animal hair and small debris over time clog filter cells, which leads to overheating of the engine and reduced cleaning quality.
In this article, we will take a closer look at the cleaning process, the differences between washable and replaceable cells, and answer frequent questions. Timely cleaning allows you to extend the battery life in wireless models and prevents the release of dust back into the air. Ignoring this stage of maintenance can lead to expensive repairs.
Before you start dismantling, it is important to determine the type of your device. Xiaomi Mi Robot Vacuum line, as well as vertical models of the Jimmy and Dreame series (the Xiaomi ecosystem) have their own design features. HEPA-The filters are similar to most of the brand’s current models.
Determination of filter type and preparation for cleaning
The first step should always be to diagnose the current state of the filtration system. Most Xiaomi robot vacuum cleaners use a multi-stage system: a pre-filter from the grid, the main one. HEPA-It's a filter and sometimes an extra engine filter. HEPA-High Efficiency Particulate Air (HEP) traps microscopic particles, including allergens and pollen.
Not all filters can be washed with water. Some models, especially older or budget versions, have compressed paper or fiberglass filters that break down when in contact with water. Carefully inspect the marking on the frame: if there is a water tap icon or the words "Washable", the item can be washed. If the icon is crossed out, only dry cleaning or replacement is available.
Workplace preparation is also important: You will need a container of warm water, a soft brush (you can use the old toothbrush), a microfiber wipe and a drying place. It is not recommended to use aggressive household chemicals, as it can damage the antibacterial coating of the cells.
The extraction process doesn't usually require tools. In robot vacuum cleaners, you just have to open the top cover and remove the dust container, and inside it, on the side or on top, there's a filter compartment. In vertical models, access is often through a lock button on the container body.
Step-by-step instructions: washing and drying HEPA-filter
If you're convinced that your filter is a washable type, you can start water treatments. The main rule here is no boiling water. The water temperature should not exceed 40 degrees, otherwise the polymer structure can deform. Carefully rinse the filter under a weak stream of water, trying to wash the dust from the depths of the folds.
☑️ Checklist of the correct wash
The use of the brush should be extremely delicate. Mechanical action is only necessary to remove lumps of dust or wool that are stuck at the entrance. You can not rub the surface with bristles - this will expand the pores and reduce the efficiency of filtration. After washing, it is recommended to gently shake off the water with light movements, but not squeeze or twist the material.
⚠️ Warning: It is strictly forbidden to use a vacuum cleaner to dry a wet filter or hair dryer. hot air will melt the structure, and a powerful airflow can damage thin fibers.
The most critical step is drying. The filter must dry horizontally at room temperature. Don't put it on the battery or dry it in direct sunlight. It takes 12 to 24 hours to dry completely. Installation of the wet element into the vacuum cleaner will cause moisture to enter the motor and mold to form inside the housing.
💡
To speed up the drying process without heating, put the filter on a dry towel and periodically change it to absorb moisture, you can also use silica gel bags, spreading them next to the filter in a closed box.
Some users mistakenly believe that light humidity is not terrible. It is not. Most Xiaomi models do not have a moisture protection system designed to directly contact water from the inside. Even a minimal amount of moisture can short-circuit or corrosion control board contacts.
Maintenance of pre-filters and nets
In addition to the main HEPA-The main filter, which is often made of metal or plastic mesh, is designed to trap large debris, hair and wool, protecting the main filter from rapid contamination.
Cleaning the nets can be carried out more often than washing HEPA-You can shake them out of the trash can and wash them under the tap, and if you've got a wool on the net, it's convenient to remove it with tweezers or scissors, carefully cutting off the knuckles, and a clogged net creates additional resistance to the air, making the motor work at a higher load.
The Xiaomi Vacuum Cleaner G10 or Dreame V11 series of vertical vacuum cleaners often feature a cyclone system, where it is important to clean not only the filters, but also the inner walls of the cyclone block.
| Type of element | Materials | Frequency of cleaning | Can I wet? |
|---|---|---|---|
| Prefilter (grid) | Metal/Plastic | Once a week. | Yes. |
| HEPA-filter | Synthetic fiber | Once every 2-4 weeks | Only if there's a marking. |
| Engine filter | Porolon/Synthepone | Once a month | Yeah (careful) |
| Laser Sensor (LDS) | Plastic/Glass | Once a month | No (wipe with a dry wipe) |
Regularly checking these components avoids situations where the vacuum cleaner is buzzing but not suctioning, often the problem lies in clogged channels between the grid and the main filter, simple maintenance takes a couple of minutes, but saves battery life.
Nuances cleaning for robot vacuum cleaners
Robotic models like the Xiaomi Robot Vacuum S10 or Viomi have a more compact filtration system, they have smaller containers, so they clog faster, pet owners are advised to check the filter after each cleaning, and hair can tightly clog cells, creating a vacuum inside the container.
The container fill sensor is a special focus, and it's often located next to the filter and can be contaminated with dust, and if the sensor is glued, the robot may not correctly detect the level of filling and stop cleaning early or, conversely, spill the dust back.
The secret of the clean side brush
In models with an automatic self-cleaning station (Auto-Empty), the filter of the vacuum cleaner itself acts as a barrier that prevents dust from escaping when blowing, and its condition needs to be given special attention, and if the filter breaks or is absent, all the collected dust will return to the room at the time of putting the robot on base.
For wet-cleaning models, it's important to separate filters. The dry-waste filter and the water filter (if there is one in the feed system) have different structures. You can't confuse them, because the paper water filter will get soaked instantly, and the HEPA for dry-waste will interfere with the flow of liquid.
Vertical vacuum cleaners: design features
Xiaomi’s wireless vacuum cleaners and sub-brands are high-powered, requiring excellent engine ventilation. Filters are often located in the tail of the device or directly above the container. The design can be composite: multiple layers of nets and sponges.
When you disassemble vertical models, it's important to remember the order of the layers. The assembly sequence is critical to create the right airflow. HEPA-filter in places, the efficiency of the vacuum cleaner will fall significantly, and the engine may overheat.
Some top-end models have a water filtration system where air passes through a water flask, and in these devices the water itself plays the role of a filter, but the output holes also need periodic cleaning of lime plaque, especially if hard water is used.
⚠️ Warning: In vertical models, never leave the container empty without a filter installed, which will cause instantaneous large dust to enter the engine turbine, causing permanent damage.
Also, check the sealing gums at the junction of the container and the filter, if the gum is dry or lost, it will form a sucker of untreated air, and the dust will bypass the filter, settling on the interior parts and exiting the engine.
When a filter replacement is needed
Even with perfect care, any filter has a limited resource. HEPA-filters wear off over time, lose electrostatic charge and stop retaining fine dust. 6-12 months depending on the intensity of use.
Signs that it is time to change the filter, not wash:
- 🧹 The filter changed its color to dark gray even after a thorough washing.
- 📉 The suction power has decreased significantly, although the engine is working at its maximum.
- 👃 When working vacuum cleaner there is an unpleasant smell of burning or mustyness.
- 🕸️ On the surface, mechanical damage, holes or fibre ruptures are visible.
Using Xiaomi’s original consumables ensures compliance with the declared characteristics. Cheap analogues can have lower material density, allowing fine dust to pass through, which is harmful to the lungs and the vacuum cleaner motor. Original filters often have antibacterial impregnation, which disappears after 5-10 sinks.
The Mi Home app for many vacuum cleaners has a filter life meter, and although it runs on a timer and doesn't take into account real pollution, you only have to dump it after you install a new one, which will help you keep maintenance statistics.
💡
Average service life HEPA-The filter is about 6 months old when cleaned regularly, and then its effectiveness drops below 60%, and saving on replacement becomes dangerous for your health.
Frequent errors in service
Many users make the typical mistakes of trying to save or speed up the process, one of the most common is drying the filter on a hot battery in the winter, which causes the fibres to dry out and break down, and the filter starts to crumble, and the particles get into the motor.
Another mistake is using a vacuum cleaner to clean the filter itself, and another vacuum cleaner's powerful airflow can break through the structure. HEPA-To knock out dust, it is better to use the method of light tapping on the edge of the shell or soft brush.
Some people try to wash filters in the washing machine, which is strictly forbidden, aggressive detergents, centrifugal force when pressed and high water temperature will completely destroy the filter properties of the product in one cycle.
