Modern robot vacuum cleaners and wireless models from Xiaomi have proven to be reliable assistants, but their effectiveness depends on the state of the filtration system. If you notice that the device has become worse at sucking dust, emitting strange sounds or simply stopped turning on, it is likely time to service the filter element. Ignoring this stage of maintenance can lead to overheating of the engine and expensive repairs.
Owners often wonder if cleaning system components can be washed and how often they should be washed. The answer depends on the type of filter installed and the intensity of the device’s use. In this article, we will examine in detail the care algorithms for various models, including the Roborock series, Viomi series and classic Mijia wireless vacuum cleaners.
Before you start disassembling, make sure you know the exact model of your device, as the design of the dust containers may differ. Mistakes in extracting can damage the latches or disrupt the tightness of the system. Let's look at the basic stages of preparation and safety.
⚠️ Warning: Before any manipulation of the filter, be sure to disconnect the vacuum cleaner from the charger and remove the battery if the model design allows this to be done.
Diagnostics of the state of the filter element
The first sign of pollution is always the visual change in the color of the filter material, the white or gray membranes eventually turn dark gray or black, but color is not the only indicator, and the decrease in traction and the change in the sound of the engine indicate that air ceases to circulate freely through the pores.
Many modern models are equipped with a smart alert system. Mi Home or Xiaomi Home can send a notification about the need for maintenance. Do not ignore such signals, as a clogged filter creates excessive pressure on the engine turbine.
There are several types of pollution that require different approaches:
- 🧶 Hair and wool: often wound onto an external mesh, blocking air access before it enters the main material.
- 🌫️ Fine dust: clogs up micropores HEPA-filters, creating the effect of a “concrete” wall for airflow.
- 💧 Wet dirt: if liquid gets into the container, the filter can swell and lose its properties irretrievably.
Regular inspections extend the life of the device, and just look inside the container once a week when you're in active use, and if you use the vacuum cleaner every day in a house with animals, you should increase the frequency of checks.
📊 How often do you clean your Xiaomi vacuum cleaner filter?
Once a week.
Once a month
Only when you stop working
Never cleaned.
Disassembly and removal of the filter
The process of filter removal depends on the design of your device. In robotic models, you usually have to flip the vacuum cleaner, press the locks and remove the lid of the main container, and inside you will see a cylinder or rectangular block, which is the filter.
In wireless vertical models like the Xiaomi Vacuum Cleaner G9 or G10, the container is often removed at the touch of a button. The filter element can be located on top (cyclone block) or inside the dust bucket itself. Be careful with plastic latches, they are made of a rather fragile polymer.
When extracting, try not to shake the filter over furniture or carpet. Raise it over the trash can or pelvis. Often, the first touch raises a cloud of fine dust, which is better not to inhale. If the filter consists of several layers, remember the order of their flow.
Dry cleaning: basic maintenance method
The most common and safe way to clean is dry, it's good for regular care and doesn't take long, you'll only need a soft brush with natural pile or a dry toothbrush, and tapping the filter on the edge of the sink helps to knock out the bulk of the dry dust.
Use the brush in a neat bottom-up motion, combing the contaminants out of the folds of the material. HEPA-For hard-to-reach areas, you can use a purge pear or a compressed air can, but blow carefully so as not to break the membrane.
Can I use a regular vacuum cleaner to clean the filter?
You can use another vacuum cleaner, but only at minimal power and without turbobrush nozzles. A powerful flow of air can damage the filter structure, and a rigid brush will tear the material. You should use blowout mode if you have one, or just walk carefully with a brush.> After mechanical cleaning, inspect the filter in bright light. If there is no light through the material or if there is a dense area of dirt, the procedure should be repeated. For multi-stage filter models, clean each layer separately. Wet cleaning is required when dry treatment no longer returns filtering capacity. It is important to understand that you can not wash all filters. Most of the filters Xiaomi and Roborock have a label in the form of a tap of water. If such a sign is absent, washing is strictly prohibited and will lead to damage to the product. If labeling permits, use only cold running water. The water temperature should not exceed 40 degrees so as not to deform synthetic fibers. Wash the filter until the draining water becomes clear. Do not use detergents, powders or underwear conditioners - they can destroy the electrostatic layer that traps microparticles. The drying process is a critical step. The wet filter cannot be installed in the vacuum cleaner - this is guaranteed to short circuit and the electronics will fail. Filter type Can I wash the drying time HEPA (main) Yes (if there is labeling) 24 hours 6-12 months Preliminary (grid) Yes 2-4 hours As pollution Coal No 3-6 months Cyclone block Yes (fully) Until drying Does not require replacement Never use a hair dryer, battery or direct sunlight to accelerate drying. High temperature can melt the adhesive base or deform the plastic frame, which will violate the tightness of the fit. Cleaning of the cyclone block and sensors Does not require replacement with a neutral filter cycle with a high amount of water, for example, the plastic filtering with a high temperature with a high temperature of the vacuum system, but with a high temperature of the filtering of the water, which is important for the vacuum with a high temperature, but the filtering of the water, for example, with a high temperature with a high temperature with a high temperature of the filtering of the filtering of the water, but the vacuum. Wash and dry thoroughly. Also, look for dust sensors if they're in the visible area. ⚠️ Warning: When assembly, make sure that the rubber seals on the cyclone block fall into place. A leakage will cause dust to leak past the filter directly into the engine. Wrapped hair on them can create additional resistance, causing the motor to work with overload. 💡The cyclone unit is cleaned up to 30% of the lost suction power, even without replacement. HEPA-Even with perfect care, the filter material is not infinite. Manufacturers recommend changing the main HEPA-filter-off 6-12 If the dust smell persists after cleaning and drying, the filter must be replaced. The original consumables can be found in the Mi Home app or on official marketplaces. Pay attention to the article when buying, as filters for different generations of robots (S5, S6, S7, S8) They can vary in size and shape of the mount: 🛒 Purchase: Purchase the original kit (usually a filter) + sidebrush). 🔄 Dismantling: Remove the old element. 🧹 Cleaning the niche: wipe the installation site with a wet wipe. ✅ Installation: insert the new filter before the characteristic click. After replacing, remember to reset the filter timer in the application, if this is provided for your model. Frequently Asked Questions (FAQ) Can a vacuum cleaner be used without a filter? Absolutely not. Working without a filter will cause instantaneous dust to enter the engine turbine. This will cause overheating, loss of power and almost guaranteed engine failure. Dust will also get on sensors and electronics. After how long can you put the wet filter back in? Minimum drying time is 24 hours at room temperature and good ventilation. Acceleration of the heating process is prohibited. Installing the wet filter will kill the electronics of the vacuum cleaner. Why does the application write about the filter, you can not put the filter in the filter, you can not clean it before the filter is cleaned. Aggressive mechanical impact of the drum and the chemistry of washing powder will destroy the structure HEPA-The filter will become useless. How often should you change the filter in the house with a cat? In conditions of high dustiness with wool and down, the filter resource is reduced in the air. 1.5-2 It is recommended to check the condition every time. 2 weekly and change the consumption once in a while 3-4 month.
