Cleaning filters in the robot vacuum cleaner Xiaomi: when, how and what to do it correctly

Xiaomi’s robot vacuum cleaners are smart assistants that save you time but require regular maintenance. One of the key procedures is filter cleaning: not only does cleaning work depend on the quality of the cleaning, but the health of the household as well. A clogged filter reduces suction, increases engine load, and can become a breeding ground for bacteria. In this article, we will discuss how to properly clean the filters in Mi Robot Vacuum, Viomi models. V2/V3, Dreame D9 And others, and also tell about the nuances that the manufacturer often does not say.

Many users make critical mistakes: washing HEPA-We've collected proven recommendations from service centers and experienced owners to make your vacuum cleaner work like new. And if you are just planning to buy – at the end of the article there is a comparative table on the types of filters in different models Xiaomi.

Why cleaning filters is not just a recommendation, but a necessity

The filters in Xiaomi’s robot vacuum cleaners serve two key functions: trap fine dust (including allergens) and protect the internal components from premature wear. HEPA-The filter loses up to 60 percent of its effectiveness after 2 months of heavy use if it's not cleaned:

• 🔋 Falling suction power: dust clogs the filter pores, and the engine has to work at the limit, which leads to overheating.
• 🦠 Bacteria Reproduction: The moist environment inside the filter (especially after floor washing) is ideal for mold and germs.
• 🚨 Mistakes in operation: many models (Mi Robot Vacuum-Mop 2 Pro, Dreame) W10) Error 10 or Error 12 codes are issued when the filter is critically clogged.
• 💰 Additional costs: ignoring cleaning leads to failure of the turbine or sensors, the repair of which costs 3-5 thousand rubles.

The manufacturer recommends cleaning filters every 1-2 weeks, but this interval depends on the operating conditions. For example, in houses with animals or during repairs, filters clog 2-3 times faster.

Signs of a clogged filter: when it's time to act

Don't wait until the vacuum cleaner is no longer able to clean.

If your vacuum cleaner is equipped with a self-diagnosis function (for example, Xiaomi Mi Robot Vacuum-Mop 2 Pro), it can issue notifications in the Mi Home app about the need to clean. Don't ignore them! In models without self-diagnosis, focus on visual inspection: take out the filter and light up with a flashlight - if the light does not pass through the material, it's time to clean.

⚠️ Note: Xiaomi robot vacuum cleaners with wet cleaning function (for example, Viomi) V3) The filters clog up faster because of the dust mixing with moisture. If after washing the floors the vacuum cleaner begins to sneeze (blow back the dust), this is a sure sign that the filter requires urgent washing.

Types of filters in Xiaomi robot vacuum cleaners: what do you have?

Depending on your vacuum cleaner model, the cleaning process may be different. Here are the main types of filters that are found in the Xiaomi lineup:

• 🔄 Removable HEPA-Filter: Installed in most models (Mi Robot Vacuum) 1/2/3, Dreame D9). Requires regular washing and replacement once in a while 6–12 months.
• 🧽 Antibacterial coated wash filter: Found in Viomi V2/V3 Mi Robot Vacuum-Mop: You can wash underwater, but not more often. 1 monthly.
• 🔋 Electrostatic filter: Used in premium models (Xiaomi Mi Robot Vacuum-Mop 2 Ultra) No washing, only dry brushing.
• 🌬️ Double filter (rough) +:: For example, in the Dream W10. Both filters must be cleaned separately.

To determine the type of filter in your model, check the documentation or look at the labels on the filter itself.

• HEPA — removable;
• Washable – if the filter can be washed
• ESD — electrostatic filter.

If you are not sure which filter is installed in your vacuum cleaner, do not risk washing it – some of the filters are not used. HEPA-It is better to take a picture of the filter and clarify the information in the official chat Xiaomi or forums (for example, 4PDA).

Step-by-step: how to clean the filter in the robot vacuum cleaner Xiaomi

Now, let's get to the point. Here's a generic guide that's suitable for most models, if you have a specific version (like DreameBot). L10), clarify the nuances in the user manual.

Disconnect the vacuum cleaner from the charging station

Getting the dust container out

Remove the filter according to the instructions for your model

Prepare tools: soft brush, vacuum cleaner, warm water (if the filter is washed)

-->

1.Dry cleaning (for all types of filters)

This step is a must, even if you plan to wash the filter later.

1. Take the filter out of the vacuum cleaner. In most models, it is under the cover of the dust container (click on the latch or pull up).
2. Remove large debris with your hands or tweezers. Don't use sharp objects - they can damage the filter material.
3. Walk through the filter with a soft brush (like a toothbrush) or use a vacuum cleaner at minimum power. Move from center to edges so you don't push the dust deeper.
4. For HEPA-filters: gently tap the filter on a hard surface (such as a countertop) to shake off fine dust.

2. Wet cleaning (only for washable filters!)

If your filter is labeled Washable, it can be washed. Do this no more than 1 time per month, otherwise the material will lose its properties.

1. Put warm water in the basin (not higher than 40).°C) and add a neutral detergent (e.g. dishwashing fluid) Do not use aggressive chemicals (bleach, vinegar)!
2. Immerse the filter in water and massage your fingers gently for 1-2 minutes. For severe contaminants, leave to soak for 10 minutes.
3. Wash the filter under a weak stream of water, holding it vertically so as not to damage the structure.
4. Do not twist or compress the filter – this deforms the fibers.

3. Filter drying

This is the most important step! Incorrect drying is the main cause of breakage after cleaning.

• 🌞 Dry the filter at room temperature away from direct sunlight and heaters.
• ⏳ Drying time: at least 24 hours HEPA-filters and 12 hours for washing.
• 💨 Do not use a hair dryer or compressor – airflow can damage microfibers.
• 🔄 Before installing, make sure that the filter is completely dry. The wet filter will become a breeding ground for mold.

Once completely dry, set the filter back, making sure it fits tightly into the body, and if the filter is deformed or torn, it needs to be replaced, otherwise dust will enter the engine.

⚠️ Note: In models with wet cleaning function (Viomi) V3, Dreame W10) After cleaning the filter, be sure to wash and dry the water tank, otherwise bacteria from the filter will get into the water for washing the floors.

How to clean the filter: allowed and prohibited means

Not all detergents are safe for filters, and here's what you can and can't use:

For dry cleaning, a vacuum cleaner with HEPA-A filter or a soft bristle brush, avoid metal sponges and hard brushes, which scratch the filter material.

💡

If the filter has a persistent odor, after washing, soak it for 10 minutes in a solution of water with 1 tbsp. l. of baking soda. This neutralizes the odors and kills bacteria without harming the material.

How often to change the filter: signs of wear and recommendations

Even with regular cleaning, filters lose their effectiveness over time, and the manufacturer recommends replacing them every 6 to 12 months, but the actual duration depends on the intensity of use.

• 🔍 Visible damage: ruptures, deformation or worn edges.
• 💨 Reduced suction power even after cleaning.
• 🦠 A persistent unpleasant odor that does not disappear after washing.
• 📉 Increased cleaning time by 30% or more.
• 🚨 Frequent errors (e.g. Error 10 or Error 12 in Mi Home).

The table below shows the approximate timeframe for replacing filters for popular Xiaomi models:

Buy filters only from authorized dealers or trusted sellers (for example, on AliExpress from 98-rated stores%+). Cheap analogues often do not provide proper filtering and can damage the vacuum cleaner. the original filter for Xiaomi costs from 500 to 1500 rubles depending on the model.

💡

If you use a vacuum cleaner to clean building dust (for example, after repair), replace the filter after 3 months - small particles of cement and gypsum quickly destroy the filter material.

Frequent Filter Cleaning Mistakes and How to Avoid Them

Many users wonder why the vacuum cleaner has become worse after cleaning the filter, most often due to errors:

1. Using hot water: HEPA-filters are made of special fibers that deform at temperatures above 40°C. The result is that the filter loses its shape and lets dust through.
2. Drying with a hair dryer or on a battery: Fast drying leads to shrinkage of the material and cracks. The filter can begin to "whistle" when working.
3. Cleaning the filter with a vacuum cleaner at maximum power: A strong airflow damages the micropores, and the filter stops trapping fine dust.
4. Use of aggressive chemistry: Bleach, vinegar or alcohol destroy the antibacterial coating and make the filter brittle.
5. Installation of a wet filter: This results in short circuit sensors or corrosion of contacts (in models with electronic filter control).

If you've already made one of these errors, check the filter for damage. HEPA-You can try to repair the filter by gently straightening it with your hands and drying it in the decomposed form, but if the material crumbles or has tears, the filter must be replaced.

Additional tips for caring for Xiaomi robot vacuum cleaner

Cleaning the filter is only part of the care, so to keep your vacuum cleaner lasting longer, follow these guidelines:

• 🗑️ Clean the dust container after each cleaning. Don't wait until it's full to the edges, which puts more strain on the filter.
• 🧹 Wash the side brushes once a week, and they're used to wrap hair and thread, which then enter the filter.
• 🔋 If the vacuum cleaner is discharged faster, check the contacts of the charging station - they could have oxidized.
• 📱 Update your firmware through the Mi Home app. Newer versions often improve cleaning algorithms, which reduces the strain on the filter.
• 🏡 Use the vacuum cleaner as intended. Do not remove construction debris, sand or liquids (except models with wet cleaning function).

If your vacuum cleaner is equipped with a self-washing function (for example, DreameBot) L10 Ultra, don't neglect it. Automatically flushing brushes and containers reduces the strain on the filter by 40 percent, but even then, the filter still needs to be cleaned manually every 1-2 months.

💡

Keep a spare filter! If you have the option, buy a second filter and change them one by one, which will allow one filter to rest and dry while the second one is running, which will prolong the life of both.
