Why cleaning the filter of the Xiaomi robot vacuum cleaner is not a luxury, but a necessity
Xiaomi's robot vacuum cleaners (including the Mi Robot Vacuum, Dreame, and Viomi) have become indispensable cleaning tools, but their effectiveness depends on the condition of the filter, which captures the smallest dust, animal hair, and allergens, and over time, the filter clogs up, and here's what happens:
The suction power decreases (the vacuum cleaner collects garbage worse), the engine load increases (which leads to overheating and shorter service life), and in the worst cases, there is an unpleasant odor. The manufacturer recommends cleaning the filter every 1-2 weeks, but how to do this correctly so as not to spoil the part? In this article, a step-by-step instruction with nuances for different models, choosing detergents and answering frequent questions.
Filters in Xiaomi robots are of two types — HEPA (They're high-efficiency, they capture up to 99.97% of the particles, and they're normal sponges, and the former require more careful care, the latter can be washed more aggressively? HEPA-filters are usually marked in gray or blue and have a dense structure with small pores.
Preparation for washing: what you need and how not to harm the vacuum cleaner
Before you start cleaning, make sure you have:
- 🧼 Warm water (not above 40)°C - hot deforms the filter material).
- 🧴 Neutral detergent: liquid soap, dishware (Fairy, AOS) or a specialised filter cleaner (e.g, Kärcher). Prohibited abrasives, bleach and solvents!
- 🧽 Soft brush (a tooth or brush for makeup is suitable) or sponge without a hard layer.
- 🌬️ A hair dryer or well-ventilated drying area (direct sunlight is not allowed!).
- 🔧 Screwdriver (for models with hidden filter mount, for example, Dreame) Z10 Pro).
⚠️ Warning: Never wash the filter directly in the vacuum cleaner case - water can damage electronic components. Always remove it before cleaning! Also check if the filter has expired: on average, the filter has expired. HEPA-filters last 6-12 months, spongy - up to 2 years. If the material has become brittle or has lost shape, it is better to replace the part.
Step-by-step: how to wash the filter of the robot vacuum cleaner Xiaomi
The cleaning process takes 15-20 minutes, but it can take 12 to 24 hours to dry.
- Disconnect the vacuum cleaner and remove the garbage container. In most models (Mi Robot Vacuum-Mop 2 Pro, Dreame D9), the filter is located inside the container or under the lid on the case.
- Pull out the filter: press the locks or turn counterclockwise (depending on the model). In the Viomi V3, the filter is mounted on the latches — gently tuck them in with a screwdriver.
- Remove large debris with a dry brush or vacuum cleaner (in blow mode). Do not shake the filter off the trash can - small particles can fly away!
- Wash under running water: 💧 For HEPA-filters: direct the jet of water from the back (where the air comes out) so as not to damage the fibers. 🧽 For sponge filters: you can slightly rub with a sponge with detergent.
Apply the detergent.
vinegar
Rinse thoroughly
Dry the filter.
- 🌬️ Natural drying: put on a towel in a ventilated place for 12–24 hours.
- 🔥 Dryer: only in cold air mode, holding at a distance of 20 cm.
The filter is completely dry (without moisture inside)| There is no visible damage on the filter | All mounts and seals are in place | The garbage container is cleaned of dust-->
⚠️ Warning: If the filter has deformed or lost its elasticity after washing, it cannot be re-installed, and this will lead to loss of leakage and dust entering the engine.
Frequent mistakes when washing the filter: what shortens the life of the vacuum cleaner
Even experienced users sometimes make mistakes that lead to breakdowns.
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of hot water (>40°C) | Filter deformation, loss of filter properties | Wash only with warm water (room temperature) |
| Drying on a battery or under the sun | Cracking of material, shrinkage | Dry in the shade at room temperature |
| Use of aggressive detergents (Domestos, Comet) | Breakdown of HEPA fibers, chemical burn of seals | Use only neutral means (pH 5–8) |
| Installation of a wet filter | Short circuit, contact corrosion, mold | Check dryness with your hand and visually |
| Cleaning the filter with a vacuum cleaner at maximum power | Damage to micropores, reduced efficiency | Use a brush or weak vacuum cleaner mode |
It's especially dangerous to combine a few errors, like washing. HEPA-The hot water filter with Domestos and dried on the battery will lose up to 70% of the filtering power after the first cleaning. In such cases, it is easier to buy a new filter (cost for Xiaomi - from 300 to 1000 rubles depending on the model).
💡
If the filter after washing began to smell unpleasant, soak it for 1 hour in a solution of water with soda (1 tbsp. spoon per 1 l).
How often to wash the filter: recommendations for different conditions
Xiaomi manufacturer indicates the average values in the instructions, but in practice, the cleaning frequency depends on the intensity of use and conditions in the house.
- 🏡 Clean apartments (1-2 people, no animals): wash the filter once every 3-4 weeks, check visually every 10 days.
- 🐶 Homes with animals: cleaning every 7-10 days (wool quickly clogs pores).
- 🚧 Repair or construction: after each cleaning! fine building dust (plaster, cement) clogs the filter in 1-2 cycles.
- 🌿 Allergies in the house: weekly wash + Replace the filter every 6 months.
- 🏢 Offices or large areas (>100 m2): check every 5 days, wash every 2 weeks.
How do you know if a filter needs to be cleaned?
- 🔊 The vacuum cleaner began to work louder (the load on the engine increased).
- 🌪️ The quality of cleaning has deteriorated (there are debris particles left).
- 👃 There was a smell of dust or dampness after switching on.
- 📉 In the mobile application (Mi Home) decreased suction or performance.

Alternative cleaning methods: when washing is impossible
There are times when you can't wash the filter or you don't have time to dry, and alternative methods can help:
- Dry vacuum cleaner: Use a soft nozzle vacuum cleaner at minimum power. Keep the nozzle 1-2 cm away from the filter so as not to damage the fibers. Efficiency: removes up to 60% of dust, but will not cope with fatty contamination.
- Compressed air cleaning: A spray can is suitable for cleaning equipment (for example, WD-40 Specialist).
- Use of sticky roller: For sponge filters, you can carefully roll a sticky roller for clothes, which will help remove wool and large particles, but will not replace a full-fledged wash.
- Ultrasonic Bath: If you have access to an ultrasonic bath (for example, for jewelry), place the filter in water with detergent for 3-5 minutes.The method removes up to 90% of contaminants, but is only suitable for durable sponge filters.
⚠️ Warning: Alternative methods are temporary, they don't replace a full wash or restore 100% of the filtering properties. After 2-3 cleanings, you still need to wash the filter with water.
Xiaomi models with filter cleaning features
Not all Xiaomi robot vacuum cleaners have the same filter design, and here are some models that require a different approach:
| Model | Type of filter | Features of cleaning |
|---|---|---|
| Mi Robot Vacuum-Mop 2 Pro | HEPA + coal layer | You can't wet the carbon layer, you can only clean it with a dry brush or a vacuum cleaner. |
| Dreame Z10 Pro | Double filter (HEPA + pre-filter) | Wash both filters separately. The prefilter can be washed in the washing machine (in a bag for delicate things). |
| Viomi V3 | Sponge-coated with antibacterial coating | Don't use vinegar or alcohol, they destroy the coating. Wash only with soap solution. |
| Mi Robot Vacuum X10+ | Self-cleaning HEPA | The filter is cleaned automatically, but once every 3 months a manual wash is required. |
To determine the type of filter in your model, check:
- 📄 Instructions (section “Maintenance").
- 🔍 Marking on the filter itself (written) HEPA, Washable or Antibacterial).
- 📱 Mobile App (Mi Home) → "The device" → "Details").
💡
If your model is equipped with a self-cleaning filter (e.g. Xiaomi X10+), it doesn’t mean it doesn’t have to be washed by hand.The automatic system only removes large debris, and fine particles and bacteria remain.
