Xiaomi's robot vacuum cleaners (including Mi Robot Vacuum, Dreame and Viomi models) require regular maintenance to keep cleaning efficiency and prevent breakdowns.One key element that is often overlooked is the filter module. HEPA-The filter not only reduces the suction power, but can also become a source of unpleasant odor or even lead to overheating of the engine.
In this article, we will discuss how to replace the filter in Xiaomi robot vacuum cleaners of different generations, including the popular models Mi Robot Vacuum-Mop 2 Pro, Dreame D9 and Viomi V3. You will learn when to replace, which consumables are suitable for your model, and how to avoid typical installation errors. And also – how to extend the life of the filter by 2 times with a simple life hack, which is not written in the official instructions.
Why it is important to change the filter in the robot vacuum cleaner
The filter in a robot vacuum cleaner is not just a mesh to trap dust. Xiaomi models use a multi-stage air purification system, where the main role is played by the system. HEPA-filter H11-H13. It traps up to 99.97% of particles 0.3 microns in size, including allergens, bacteria and microscopic dust. If the filter is clogged, the consequences can be serious:
- 🔴 Reduced suction power by 30-50% — Robots are worse at collecting garbage and more often stuck on carpets.
- 🤧 Allergens spread – instead of cleaning the air, the vacuum cleaner begins to “blow” dust back into the room.
- 🔥 Overheating of the engine - due to increased load, an emergency shutdown may trigger or the life of the turbine will be shortened.
- 🦠 Mold and smell – wet cleaning in models with floor washing function accelerates the reproduction of bacteria in a clogged filter.
The manufacturer recommends changing the filter every 2-3 months during daily cleaning, but the actual duration depends on the operating conditions. For example, in houses with animals or when cleaning construction dust, the filter may become unusable within 4-6 weeks.
Signs that the filter needs to be replaced
Don't wait until Xiaomi's robot vacuum cleaner is completely ineffective, and the following symptoms suggest that the filter needs to be replaced:
| Sign. | What's going on? | Degree of criticality |
|---|---|---|
| Reduced suction force | Robot worse collects garbage, especially fine dust and animal hair | ⚠️ Medium |
| Extraneous sounds | The engine is running louder, wheezing or wheezing is heard when suctioning | ❗ Tall. |
| Smell after cleaning | From the robot or from the dust collector comes musty or dusty smell | ❗❗ Critical |
| Frequent errors | Vacuum stops with error Filter clogged or overheating | ❗❗ Critical |
| Visible damage | The filter is deformed, torn or covered with mold | ❗❗❗ Immediate replacement! |
If you notice any of these signs, don’t delay replacing. In wet-cleaning models (such as the Xiaomi Mi Robot Vacuum-Mop P), a polluted filter can cause the pump or electronics to break due to high humidity.
⚠️ Attention: In the robot vacuum cleaners Xiaomi Dreame series Z10 Pro and D9 If you smell a chemical odor when cleaning, it's a sign that the carbon layer has exhausted its life and needs to be replaced, even if the filter looks clean.
What filters are suitable for Xiaomi robot vacuum cleaners
Not all filters are universal – each Xiaomi model requires its own consumables. The table below shows compatible filters for popular series. Note that some models (for example, the Viomi V3) use two filters: the main HEPA and pre-cleaning (mesh).
| Model robot vacuum cleaner | Type of filter | Original article | Analogues (brands) |
|---|---|---|---|
| Mi Robot Vacuum 1/1S/1C | HEPA H11 | ZNMS01WM | Baseus, Remax, Roborock |
| Mi Robot Vacuum-Mop 2 Pro | HEPA H12 + coal layer | ZNMS07WM | Dreame, Ecovacs |
| Dreame D9 / D9 Pro | HEPA H13 + antibacterial coating | DR-MF01 | Xiaomi Mi, Viomi |
| Viomi V2 / V3 | Double: grid + HEPA H11 | V-RVF01 (set) | Cecotec, ILIFE |
When choosing analogues, look for a filter class (H11, H12 or H13) and additional layers (carbon, antibacterial). Cheap uncertified filters can not only purify the air worse, but also damage the engine due to increased resistance to air flow.
⚠️ Note: Xiaomi Mi Robot models with laser navigation (LDS) Using unoriginal filters can cause false alarms of dust sensors and frequent robot stops with the error The dust collector is full, even if the container is empty.

Step-by-step instructions for replacing the filter
The process of replacing the filter in Xiaomi robot vacuum cleaners takes no more than 5 minutes, but requires care. Below is a universal instruction that is suitable for most models. If you have a specific series (for example, Viomi SE or Dreame W10), refer to the section with the features for these vacuum cleaners.
Turn off the robot vacuum cleaner and take out the battery (if possible)
Clean the dust collector of garbage
Prepare a new filter and wipe for cleaning.
Check the integrity of the sealing rubber bands on the cover
-->
Step 1 - Disconnect and disassemble
Turn off the vacuum cleaner with the power button or through the Mi Home app. Turn the robot bottom up and remove the vacuum collector by pressing the latch (in most models it is located at the back). In models with the floor washing function (Mi Robot Vacuum-Mop), pre-pump the water from the tank.
Step 2: Remove the old filter
Open the filter cover, which can be mounted on latches or screws (old Mi Robot 1 models). Take the filter out carefully by pulling it upwards. If the filter is stuck with moisture (wet cleaning models), don't pull it by force, put it on the edge with a plastic map.
Step 3. Clean the compartment.
Before installing a new filter, wipe the internal cavity of the dust collector with a dry wipe or vacuum cleaner. Pay attention to the air channels - the accumulation of dust there can cause an error Clogged duct. In Dreame D9 models, additionally check the condition of the prefilter (net insert before HEPA).
Step 4: Installation of a new filter
Place the new filter in the groove, combining the tags (usually an arrow or FRONT inscription). Make sure the sealing gum fits tightly to the edges - this will prevent the suction of unfiltered air. Close the lid before you click.
Step 5: Checking the performance
Turn on the vacuum cleaner and start the test cleaning. In the first 1-2 minutes of operation, you may hear increased noise - this is normal, since the new filter has more resistance. If the robot gives an error Filter is missing, check if the identification chip is installed correctly (in models with electronic filter control).
💡
If the filter is changed, make sure you mix up the top and bottom of the filter. Most Xiaomi models have a TOP or arrow on the filter that indicates the correct position.
Features of filter replacement in popular models
While the principle of filter replacement is similar in all Xiaomi robot vacuum cleaners, some models have nuances. Below we will discuss the most common series.
Xiaomi Mi Robot Vacuum 1/1S/1C
In these models, the filter is mounted inside the dust collector on two plastic latches, and the main feature is that there is no electronic chip, so you can use any compatible filters without the risk of error. However, the Mi Robot 1C has a dust sensor that can falsely trigger when using cheap analogues.
Xiaomi Mi Robot Vacuum-Mop 2 Pro / P
It uses a combined carbon-layer filter to neutralize odors. When replacing, be sure to check the gasket between the vacuum collector and the housing - its damage leads to the suction of unfiltered air. In these models, the filter has an identification chip, so non-original consumables can cause a non-original filter error (although the robot will work).
Dreame D9 / D9 Pro / Z10 Pro
The filter in these vacuum cleaners has an antibacterial coating and increased resource (up to 6 months).When replacing, pay attention to the prefilter - it must be washed with water every 2 weeks. In the Dreame Z10 Pro, the filter is integrated with the detergent module, so before replacing it, you need to drain the water and dry the tank.
Viomi V2 / V3 / SE
The feature of these models is a dual filtration system: a mesh prefilter and HEPA. When replacing, be sure to check both elements. In the Viomi V3, the filter is mounted on a screw (T6 screwdriver), not on the latches. These vacuum cleaners also use a magnetic lid closure sensor, if the filter is installed incorrectly, the robot will not turn on.
💡
In Xiaomi models with the function of self-cleaning the base (for example, DreameBot X30), the replacement of the filter in the vacuum cleaner must be combined with cleaning the filter in the docking station - otherwise the cleaning efficiency will decrease by 40%.
How to extend the life of the filter: 5 proven ways
Original filters for robot vacuum cleaners Xiaomi are from 500 before 1500 The ruble, and they have to change every time. 2-3 However, there are ways to increase the interval between replacements without compromising the quality of cleaning.
- 🧹 Regular cleaning of the prefilter. The mesh filter (if you have one in your model) can be washed with water once in a while. 1-2 It'll take a little bit of time. HEPA-filter.
- 🌬️ Blow in compressed air. Blow in once a month. HEPA-a compressor or compressed air canister (holding the balloon at a distance of 10 cm) filter, which removes up to 70% of the accumulated dust.
- ☀️ Drying in the sun. After wet cleaning (in models with a mop), remove the filter and dry it. 2-3 hours in direct sunlight - ultraviolet light kills bacteria.
- 🚫 Avoiding "severe" contamination. Don't use a robot to clean up building dust, sand or the hair of large dogs -- it clogs the filter for the scaling. 1-2 cleaning.
- 🔄 Alternating filters. Buy two filters and change them once a month, giving the second one a rest. 30-40%.
⚠️ Warning: Never try to wash HEPA-A filter in water destroys its microstructure and reduces the filtration efficiency by up to 40%, allowing only dry brushing or air purging.

Frequent Filter Replacement Mistakes and How to Avoid Them
Even a simple procedure like changing a filter can go wrong, and here are some of the most common mistakes Xiaomi robot vacuum cleaners make and how to prevent them:
- 🔄 Upside down, 80 percent of the time, it causes a missing filter or a noise. Always check the tags. TOP or FRONT.
- 🧲 Ignoring the magnetic sensor. In Viomi and some Dreame models, the filter cover is magnetized -- if it's not closed before the click, the robot won't turn on.
- 🔧 Loss of screws or latches. V3 And Mi Robot 1 is a screw-mounted filter cover, which is easy to lose.
- 💧 Install a wet filter. Even after sun drying, the filter must be completely dry. The moisture shortens the sensors in electronically controlled models.
- 🛒 Buying an incompatible filter, for example, the Mi Robot Vacuum 1 filter is not suitable for Dreame. D9, despite the appearance of the similarity, always check the article.
If after changing the filter, the robot gives an error or works incorrectly, reset the settings through the Mi Home application (Device Settings). → Resetting: 90% of the time, this solves the problem of recognizing the new filter.
