Xiaomi vacuum cleaners are not just gadgets for the lazy, but high-precision devices that require regular maintenance. One of the most vulnerable elements in them is a thin filter that over time gets clogged with dust, animal hair and microparticles. If you ignore its condition, the vacuum cleaner will become worse at sucking up garbage, emitting unpleasant smells or even fail. In this article, we will discuss how to properly care for the filter in Mi Robot Vacuum, Dreame and Viomi models to prolong the life of the equipment and maintain the quality of cleaning.
Many users make critical mistakes: wash filters under running water, dry them with a hair dryer or forget to replace them at all, we will tell you what filters are available (HEPA, coal, multi-layer), how to clean them depending on the type, and when it is time to buy a new one, and also share life hacks on how to save on consumables without compromising the vacuum cleaner.
What filters are used in Xiaomi robot vacuum cleaners
In the line of Xiaomi there are three main types of filters, and their design depends on the way of care:
- 🔹 HEPA-filters (class) H11-H13) — They can capture up to 99.9% of the 0.3 microns in size, and are installed in most models, including the Mi Robot Vacuum-Mop 2 Lite and Dreame. D9. Require careful cleaning and timely replacement.
- 🔹 Coal filters – additionally absorb odors, found in premium series, for example, Xiaomi Mi Robot Vacuum X10+. They can not be washed, only replaced.
- 🔹 Multi-layer filters – combine HEPA-antibacterial treatment layer used in Viomi V3 and some of the Dreame models.
Importantly, the filters in Xiaomi robot vacuum cleaners are not interchangeable even between similar models. For example, the filter from Mi Robot Vacuum 1S will not be suitable for the Dreame Z10 Pro, despite the appearance of similarities. Always check compatibility by article or serial number of the device.
How do you identify the type of filter in your model? Go to the manual or look for the label on the filter itself, which is usually printed on the plastic case in fine print. If documentation is lost, use Mi Parts, where you can pick up parts from the vacuum cleaner model.
How often should the filter be cleaned and changed?
The frequency of maintenance depends on the intensity of the vacuum cleaner and the conditions in the house.
| Conditions of operation | Cleaning the filter | Replacement of the filter |
|---|---|---|
| Clean apartment, 1-2 cleanings per week | 1 time 2-3 weeks | Every 6-8 months |
| Pets and daily cleaning | 1 time per week | Every 3-4 months |
| Allergic in the family, high dustiness | Every 3-5 days | Every 2-3 months |
| Office or public space | After every cleaning. | Every month. |
Signs that the filter needs urgent attention:
- 🚨 The vacuum cleaner became worse to suck up garbage, leaves a mark on the carpet.
- 🚨 There was a smell of dust or burns when working.
- 🚨 Cleaning time increased (the robot cleans the same area longer).
- 🚨 On the display or in the Mi Home app appeared warning Filter Blocked or Clean Filter.
⚠️ Note: If you use a vacuum cleaner for wet cleaning (e.g. Dreame) W10), The filter wears out 1.5-2 times faster due to high humidity, and in such models it must be changed every 2-3 months, regardless of the external condition.
Step-by-step: how to clean the filter correctly
The process of cleaning the filter seems simple, but there are nuances that many people miss. Follow this instruction so that you do not damage the filter and shorten its life:
- Remove the filter. Turn off the vacuum cleaner and flip it over. Press the latch (usually marked with an arrow or PUSH) and carefully pull out the dust container with the filter. In some models (for example, the Viomi V2 Pro), the filter is attached separately, you need to pull it up.
- Removing large debris. Shake the filter dust off the trash can or use a soft brush (or toothbrush) and don't tap the filter on hard surfaces, which can damage the structure.
- Wash (washing filters only!) If your filter is labeled Washable (like in Dreame D9), rinse it under cold water without detergents. Temperatures above 40°C warp HEPA fibers. Keep the filter vertical so that water drains down rather than penetrates into the layers.
- Dry. Put the filter on a clean towel in a well-ventilated place. Don't dry with a hair dryer, battery or direct sunlight, it will crack the material. Drying time: at least 24 hours.
- Reverse installation: Make sure the filter is completely dry before inserting it back in. moisture inside the vacuum cleaner can cause a short circuit or mold to appear.
Check filter type (washable or not)|Unplug vacuum cleaner from the network |Prepare a soft brush and napkin |Make sure there are no drafts in the room (for drying) |Plan 24 hours to dry-->
For coal and some HEPA-Filters (e.g. Xiaomi Mi Robot Vacuum) E10) It's forbidden to wash, it can only be pile-sucked or cleaned with a brush, and if the filter is deformed or has lost color, it's time to replace it.
💡
To extend the life of the filter, shake the garbage out of the container before each cleaning, and the less dust that gets on the filter, the longer it will last.
How to Replace a Filter: Selecting and Installing a New Filter
When cleaning doesn't work, it's time to replace it. Here's how to choose and install a new filter without any errors:
1. Selection of compatible filters. Use original parts or certified analogues. For popular models, suitable articles:
- 🛒 Xiaomi Mi Robot Vacuum 1/1S/1C — filter ZSTNQ02ZM or CQGNZ02ZM.
- 🛒 Dreame D9/D10 — filter DMFILT01 (coal-fired DMFILT02 (HEPA).
- 🛒 Viomi V3/V2 Pro - filter V-RVC02.
2. Check before buying. Check the size and shape of the filter with what is installed in your vacuum cleaner. Some Chinese counterparts may look identical, but have a lower density of material, which causes dust to pass through.
3. Install. Carefully insert the new filter into the socket before you click. Make sure it sits tightly - the gaps will lead to unfiltered air entering the engine. After replacing, reset the filter wear meter in the Mi Home app (Settings → Reset → Reset filter).
⚠️ Warning: If the vacuum cleaner is louder or whistled after the filter is replaced, check if the filter is installed correctly, it may be skewed or not fully inserted, and the whistle may indicate clogging of air channels (they need to be cleaned with a toothpick).

Top.-5 Filter care errors (and how to avoid them)
Even experienced users sometimes do things that shorten the life of the filter or ruin the vacuum cleaner.
- Washing unwashed filters. Coal and some HEPA-Filters (e.g. Xiaomi Mi Robot Vacuum) X10+) You can't wet it. The water breaks down the activated carbon and the glue that holds the fibers together.
- The consequence: the vacuum cleaner loses the suction power by 20-30%.
- Drying in the microwave or oven, high temperature melts the synthetic filter fibers, and the consequence is that the filter is deformed and doesn't fit in.
- Ignoring the app's warnings: When a vacuum cleaner signals a filter clog (Error 10 in Dreame or Filter Blocked in Mi Robot), it needs to be cleaned immediately, the consequence: overheating of the engine and failure of the turbine.
- Buying cheap ones, uncertified filters often have low density, which allows up to 40 percent of the dust to be released back into the air, and then allergic reactions, rapid wear and tear on the motor.
How to avoid these mistakes? Follow a simple rule: if in doubt, read the instructions. In the manual for each Xiaomi model there is a section on filter care with precise recommendations. For example, for the Dreame F9, it is forbidden even to wipe the filter with a wet wipe - only dry cleaning.
💡
HEPA-filters lose up to 50% of their effectiveness after 3-4 washes, even if they look clean. Regular replacement is more important than trying to "reanimate" an old filter.
How to prolong the life of the filter: life hacks and prevention
The service life of the filter can be increased by 1.5-2 times if you follow these tips:
- 🧹 Clean the dust container after each cleaning, the less debris that gets on the filter, the longer it will last, and use a mini vacuum cleaner or a wet wipe to remove dust from the gap between the container and the filter.
- 🧹 Install an external dust collector for models with support (e.g. Dreame) W10) You can buy an external station that automatically cleans the container after cleaning, which reduces the load on the filter by 60%.
- 🧹 Use a vacuum cleaner at medium power. Maximum mode (Max or Turbo) clogs the filter faster. Standard mode is enough for everyday cleaning.
- 🧹 Clean brushes and rollers regularly. Tangled hair and threads increase the amount of dust that enters the filter. Remove and wash the side brushes once a week, and clean the main roller with scissors.
- 🧹 Keep your spare filters in a sealed bag. If you buy your own filters, don't leave them open, they soak up moisture and dust from the air.
For owners of Xiaomi Mi Robot Vacuum-Mop 2 Pro and similar models with wet cleaning function, there is a separate life hack: after cleaning, leave the vacuum cleaner for 1-2 hours with an open drying container. This prevents mold from forming on the filter.
If you live in a high-humidity region (like St. Petersburg or Sochi), treat the filter with an antibacterial spray (any air conditioner is suitable), which will prevent the fungus from multiplying. Apply the spray once a month on a dry filter, then let it dry for 10-15 minutes before installing.
What to do if the filter is damaged or lost
Sometimes the filter breaks when cleaning, gets lost or deformed, and here's what you can do in these cases:
1. Temporary replacement: If the new filter has not been purchased and cleaning cannot be delayed, use as a temporary replacement:
- 🧻 folded in several layers gauze or nonwoven material (for example, from a disposable mask).
- 🧻 Filter from household vacuum cleaner, cut in size (suitable only for dry cleaning!).
- 🧻 Special wipes for vacuum cleaners (sold in hardware stores).
⚠️ Warning: These replacements do not filter 100% of the air and can damage the engine if used for long periods of time.
2. Repair the torn filter. If the filter breaks at the edge, it can be neatly glued with thermoglue (not superglue!). The key is not to glue the filter surface, which is only suitable for multi-layer filters where the top layer is damaged.
Check the vacuum cleaner after the incident, if the filter was installed incorrectly or was not at all, check:
- 🔍 Is there any dust inside the air channels (clean them with compressed air).
- 🔍 Does the vacuum cleaner warm up after 10 minutes of work.
- 🔍 Is there any extraneous sounds (squeaking, whistling) - this may indicate the entry of debris into the turbine.
⚠️ Warning: If the vacuum cleaner starts to smoke or smell like a burn after cleaning without a filter, turn it off immediately and contact the service. Most likely, dust got on the electric motor, which can lead to a fire.
