Xiaomi vacuum cleaners are indispensable cleaning aids, but their effectiveness depends on the state of the dust collector. A clogged container not only reduces suction power, but can also lead to engine overheating or turbine failure. In this article, we will discuss how to properly clean the dust collector in Mi Robot Vacuum, Viomi V2/V3, Dreame D9 and others to prolong the life of the device and maintain the quality of cleaning.
You'll learn not only the basic cleaning procedure, but also the nuances of how often to do it, what tools to use, and what to do if the dust collector is jammed or begins to smell unpleasant, and we'll highlight some common mistakes that reduce the life of the vacuum cleaner, and give recommendations for the care of filters and brushes.
Why it is important to clean the dust collector regularly
The dust collector is not just a garbage can, but a key part of the suction system, and when it fills up, there are several problems at once:
- 🔋 Reduced suction power – the robot worse collects dust, hair and small debris, leaving them on the floor.
- 🔥 Overheating of the engine – a clogged container creates additional load on the turbine, which can lead to its failure.
- 🦠 Bacterial reproduction – wet dust and organic residues (such as animal hair) become breeding grounds for mold and microbes.
- 🚨 False sensors – some Xiaomi models block work if the dust collector is full, giving an error Error 10 or Clean the dustbin.
According to service centers, up to 40% of Xiaomi robot vacuum cleaner breakdowns are due to late cleaning of the vacuum cleaner, and many users only clean it when the robot begins to sneeze or emits an error, which is already a critical stage.
What tools will be needed for cleaning
For high-quality cleaning of the dust collector, special devices are not needed, but some tools will greatly facilitate the process:
| Tool. | What do you need? | The alternative |
|---|---|---|
| Soft brush (e.g. toothbrush) | Removal of dust from hard-to-reach places (gratings, filter) | Paintbrush |
| Narrow-filled vacuum cleaner | Blowing dust from internal channels | Fryer in cold air mode |
| Wet wipes (without alcohol) | Cleaning of internal surfaces from sticky dirt | Microfiber fabric moistened with water |
| Screwdriver (cross-haired) | Disassembly of the dust collector in models with a fixed filter (for example, Viomi V3) | Plastic mediator |
| Soap solution (neutral detergent) | Washing removable parts (only for models with a collapsible container!) | A dishwasher |
⚠️ Warning: Never use aggressive chemicals (acetone, gasoline, solvents), hard brushes or metal objects to clean a Xiaomi dust collector, which can damage plastic, seals or filters, leading to loss of leakage and worsen absorption.
Also avoid washing non-collectible dust collectors under running water - in some models (for example, Dreame Bot W10) filling sensors are located inside the container, which will fail if moisture enters.
Step-by-step: how to remove and clean the dust collector
The cleaning process may vary slightly depending on the model, but the overall scheme is the same for most Xiaomi robot vacuum cleaners.
- Turn off the robot and take it out of the dock (if any). Make sure the device is not in cleaning mode - the indicator should be blue or white (not red!).
- Open the dust collector cover. Most models have it on top and it's latched. Press the button or pull the lid on you (Mi Robot Vacuum-Mop 2 opens the lid sideways).
- Remove the container. Pull it up carefully, it should come out without effort. If the dust collector is jammed, do not pull it (see "What to do if the dust collector is not removed").
- Remove the garbage. Turn the container over the trash can and tap on it. Use a brush or vacuum cleaner to remove the adhering dust.
- Clean the filter. Most Xiaomi models have a removable filter (round or rectangular), can be washed under warm water (if permitted in the instructions), or cleaned with a brush. The filter in the Viomi V2 can not be wet, only blown with air!
- Wipe the inner surfaces. With a wet wipe, remove dust from the sealing gums and the walls of the container. Pay attention to the lattice through which the air passes.
- Make sure the filter is dry and tightly inserted, and the dust collector cover is snapped to a characteristic click.

⚠️ Warning: After cleaning the dust collector, do not turn the robot on immediately - wait 10-15 minutes for moisture (if it remains) to evaporate. Otherwise, the sensors may falsely work, and the robot will refuse to start cleaning.
How often should the dust collector be cleaned?
The frequency of cleaning depends on the intensity of the robot's use and the type of garbage collected.
- 🏠 Daily cleaning in an apartment without animals - cleaning the dust collector every 3-5 days.
- 🐕 Pets (wool, filler) – cleaning after each cleaning or every 1-2 days.
- 👶 Children's room (small garbage, crumbs) - once every 2-3 days.
- 🌿 Country house (folios, sand) - after each cleaning, as such garbage quickly clogs the filter.
Some Xiaomi models (such as the Dreame Bot Z10 Pro) are equipped with dust collector filling sensors and remind them of the need to clean through the Mi Home app. However, relying on sensors alone is not necessary - they can be triggered late, especially if the dust is fine (for example, cement after repair).
💡
If your robot vacuum cleaner has started making unusual sounds (whistling, grinding) or worse picking up debris along the boards, this is a sure sign that the dust collector requires urgent cleaning, even if visually it seems half-empty.
For models with automatic dust collector cleaning function (for example, Xiaomi Mi Robot Vacuum-Mop 2 Pro with docking station), the manual cleaning frequency is reduced to 1 time every 1-2 weeks.
What to do if the dust collector is not removed
Sometimes the garbage can jams and doesn't come out when you press a button.
- 🧲 Dust or hair caught in the fixation mechanism - the most common problem.
- 🔧 Deformation of plastic (for example, after the fall of the robot).
- 🔋 The lid was skewed due to incomplete closure last time.
Here's how to solve the problem:
- Try to gently swing the container left and right while pulling it up. Don't put too much effort into it!
- Use a plastic card (like a bank card) to plug the lid on the side, insert it into the slot and gently press it to simulate the latch press.
- Blow the latch with compressed air (such as a canister to clean the keyboard) and this will help remove dust blocking the mechanism.
- Take the robot apart partially (only if you are confident in your abilities!) In some models (for example, the Viomi SE), it is enough to remove the top cover to access the dust collector lock.
⚠️ Note: If the dust collector is not removed even after these manipulations, do not try to pull it out by force - this can break the latch or damage the case. Contact the Xiaomi service center, specifying the error code (if it is displayed on the screen or in the application).

How to eliminate the unpleasant smell from the dust collector
If a robot vacuum cleaner Xiaomi started to emit an unpleasant smell, it means that the dust collector accumulated organic waste (wool, food residue, pollen) and began to rot.
- Deep cleaning of the container: Remove the dust collector and filter. wash them with warm water and soap (if allowed for your model!). Use vinegar solution (1:1 with water) or special antibacterial wipes. Dry all parts thoroughly (at least 12 hours outdoors).
Soda treatment: Sprinkle the bottom of the dust collector with baking soda, leave for 1-2 hours, then remove with a vacuum cleaner. Soda neutralizes the smells.
Replacement of the filter: if the smell does not disappear, most likely, the filter is soaked in dirt. In Xiaomi models, it is recommended to change the filters every 3-6 months (articles: WXCBC01ZM for Mi Robot, VACFIL01 for Viomi).
Prevention: After each cleaning, shake the dust collector and wipe it with a napkin. Wash the container once a month (if applicable).
⚠️ Warning: Don't use flavors or air fresheners to remove the smell! Particulates can settle on the robot's sensors and disable them. Also avoid chlorine-containing products, which corrod plastic and rubber seals.
💡
If the smell is bad even after cleaning, check if the dust collector has got liquid (for example, when cleaning spilled juice), in which case a complete dismantling and drying of the robot in the service center is required.
Frequent errors in cleaning the dust collector
Even experienced users sometimes make mistakes that shorten the life of a robot vacuum cleaner.
- 🧹 Using a vacuum cleaner to clean the filter destroys its fibers and reduces efficiency. The filter can only be washed (if allowed) or blown with air.
- 💦 Assembly of wet dust collector - leads to corrosion of metal parts and short circuit sensors.
- 🔌 Cleaning the robot when switched on – the risk of damage to electronics or accidental launching of blades.
- 🧼 Application of detergents for non-shatterable containers - the liquid will enter the engine through the ventilation holes.
- 🗑️ Throwing garbage from the dust collector into the sink - hair and thread can clog the drain.
Another common mistake is ignoring sealing gums, which eventually become a sticky dust layer and stop sealing the container, which leads to debris entering the turbine and worsening suction, and the rubber bands need to be wiped with a wet wipe every 2-3 cleanings.
Also, many users forget to check the secondary filter (if there is one in the model). L10 In addition to the main filter in the dust collector there is an additional HEPA-The filter at the back of the case, which should be cleaned every 1-2 months.
