The filters in Xiaomi's robot vacuum cleaners are a critical element that not only determines the quality of the cleaning, but also the life of the device. A dust-filled filter reduces suction power, increases engine load and can cause engine failure. However, many users face difficulties in trying to extract it: unclear latches, afraid to break plastic parts or simply do not know where it is located.
In this article, we will take a step-by-step look at the steps for all popular Xiaomi models (including Mi Robot Vacuum, Viomi, Dreame), show you how to avoid typical cleaning errors, and give you tips for care, and you will learn how to remove the filter incorrectly and how often it needs to be changed.
If your vacuum cleaner is getting worse at collecting dust, making uncharacteristic sounds, or discharging quickly, the first reason may be in the filter. Even if you regularly clean the garbage container, the filter itself requires special attention. In some Xiaomi models, it is hidden so deep that it is difficult to get to it without instructions. But don't worry: after reading this article, you can do it in 2-3 minutes.
Where is the filter in Xiaomi’s robot vacuum cleaners?
Most models have filters inside the dust collector, but their location and attachment may vary.
- 🔹 Classical models (Mi Robot Vacuum) 1/2, Mi Robot Vacuum-Mop: The filter is located at the top of the dust collector, under the lid with a latch.
- 🔹 Self-cleaning models (Dreame Bot) Z10 Pro, Viomi V3): filter integrated into the cyclone cleaning system, often hidden behind an additional panel.
- 🔹 Hybrid models (Xiaomi Mi Robot Vacuum-Mop 2 Pro): the filter can be divided into two elements - rough and fine cleaning, located in different compartments.
To determine exactly where to look for a filter in your model, look at the labeling on the body of the dust collector. 🌬️ or FILTER. If you don’t find a filter the first time, don’t apply force – in some vacuum cleaners (like Dreame Bot). L10 Pro) it's hidden under a removable grille.
Important: In models with wet cleaning function (Mi Robot Vacuum-Mop P), the filter can be combined with a water tank, in which case its removal requires the first disconnection of the liquid tank.
Step-by-step: how to get a filter from a Xiaomi vacuum cleaner
Consider a universal algorithm that works for most models, and if your vacuum cleaner has a unique design, below are some of the instructions for the popular series.
Step 1. Turn the vacuum cleaner off the power supply
Before any manipulation of the internal parts, be sure to remove the vacuum cleaner from the docking station and turn it off with a button on the case. This will prevent accidental start during disassembly. In models with a removable battery (for example, the Viomi V2), you can additionally remove the battery.
Step 2. Remove the dust collector
Press a button or latch (usually located on the back or side panel) and pull the garbage container over yourself. In some models (Dreame Bot D9), the dust collector is fixed with magnets - it must be carefully "shifted" upwards.
Step 3. Find and remove the filter cover
Inside the dust collector, you'll see a plastic lid with latches or threaded mounts, gently press the latches or turn the lid counterclockwise (depending on the model). Don't use sharp objects, it can damage the seals.
Step 4. Get the filter out.
Once the lid is removed, the filter can be removed by pulling a special loop or simply removing it with your hands. HEPA-Filters (for example, Mi Robot Vacuum-Mop 2 Lite) can be enclosed in a plastic cartridge - it also needs to be disassembled.

If the filter doesn't respond, don't pull it by force, it may be fixed by an additional mount, and see the section below with specific model instructions.
Features of filter extraction in popular models
Some of Xiaomi's robot vacuum cleaners have a unique design, and we've compiled detailed instructions for the most common series.
| Model | Type of filter | How to extract | Features |
|---|---|---|---|
| Mi Robot Vacuum 1/2 | HEPA + spongy prefilter | Remove the cover of the dust collector, pull the filter loop | The filter is mounted on the latches, easily breaks with strong pressing. |
| Dreame Bot Z10 Pro | Cyclone + HEPA | Open the top panel, remove the cyclone block, then remove HEPA-filter | Cleaning of the cyclone block after each extraction is required |
| Viomi V3 | Coal + HEPA | Turn the cover of the dust collector 90°, remove the filter with the holder | The carbon filter cannot be washed, only replaced. |
| Mi Robot Vacuum-Mop 2 Pro | Double (rough + fine cleaning) | Remove the dust collector, divide it into two parts, remove the filters alternately | The filter of rough cleaning can be washed with water |
For the Dreame Bot L10 Pro and Xiaomi Mi Robot Vacuum-Mop P, the process is complicated by the presence of a self-cleaning system, where the filter is integrated into the dust collector and mounted on the thread.
- Unscrew the dust collector counterclockwise.
- Remove the top cover by pulling up.
- Remove the cylindrical filter by pressing the locks on the sides.
Tip: If the filter is stuck with dust, don't try to pull it out. Put the dust collector in warm water for 10-15 minutes, the dirt will get wet, and the part will easily be removed.
💡
Dry all the parts for at least 24 hours before assembly. A wet filter can cause a short circuit in the vacuum cleaner.
Cleaning and replacing the filter: what can and can not be done
Removing the filter is only half the battle, and now you have to clean it properly or replace it properly.
- 🚫 Don't wash. HEPA-The water destroys the microfibers, and the filter loses its properties.
- ✅ Use a vacuum cleaner – this is the safest way to remove dust.
- 🔄 Change the filter every 3-6 months (depending on the intensity of the cleaning).
- 🧼 To wash spongy prefilters, use only cold water and a soft detergent.
If you decide to replace the filter, buy only original parts or certified counterparts. For example, for Mi Robot Vacuum 2, a filter with the ZSTYJ02ZM article will suit, and for Dreame Bot Z10 Pro - DM-Z10-FILTER. Non-original filters may not fit tightly, which will lead to dust entering the engine.
Critical error: using the filter after the expiration of its life can cause the vacuum cleaner to overheat and the turbine to fail. If you notice that after cleaning the filter, the vacuum cleaner still does not suck well, check the sealing gums - they may have deformed.

Typical Filter Errors and How to Avoid Them
Even experienced users sometimes make mistakes that can damage the vacuum cleaner, and here are the most common ones:
⚠️ Warning: Never pull the filter over the edges — most Xiaomi models have it mounted on plastic latches that break easily. Always take a special loop or centerpiece.
- 🔧 Use force on a jammed filter. If it doesn't come out, check if it's caught on another element (e.g., a brush in a dust collector).
- 💦 Washing of non-collectible filters. HEPA-filters in Viomi and Dreame can not be wet - only blown with air or brushed.
- 🔄 If the vacuum cleaner is louder after cleaning, check if the filter cover is tightly closed and if there are any cracks.
Another common problem is the loss of small parts (such as sealing rings or mesh) to avoid this, disassemble a vacuum cleaner on a table with a light surface or use a magnet for fasteners (if you have them in your model).
If you find that the filter is deformed or torn after removing it, never put it back in, and it will cause dust to enter the engine and break down, and in a temporary solution, you can use a dense fabric (e.g., microfiber) folded in several layers, but order a replacement as soon as possible.
💡
Before cleaning the filter for the first time, take a picture of its location in the dust collector, which will help to collect everything back correctly and avoid errors.
How often should the filter be cleaned or changed?
The frequency of filter maintenance depends on the intensity of the vacuum cleaner and the type of coating in your home.
| Conditions of operation | Cleaning the filter | Replacement of the filter |
|---|---|---|
| Apartment with laminate / tile, cleaning 2-3 times a week | 1 time per month | 1 time in 6 months |
| House with carpets, daily cleaning | 1 time 2 weeks | 1 time 3-4 months |
| Presence of domestic animals | 1 time per week | 1 time 2-3 months |
| Allergic in the house | After every cleaning. | Strictly according to the regulations (at least 1 time in 3 months) |
If you use a wet vacuum cleaner (such as the Xiaomi Mi Robot Vacuum-Mop 2), the filter gets polluted faster due to high humidity, in which case clean it after every 3-4 cleaning cycle.
Signs that the filter needs to be replaced:
- 🌪️ The vacuum cleaner became worse to suck up garbage.
- 🔊 There's more noise at work.
- 🔋 Battery life is reduced by 20% or more.
- 🤧 After cleaning, visible dust remains on the surfaces.
