Step-by-step: how to clean the filter of the robot vacuum cleaner Xiaomi Mi without errors

Xiaomi Mi Robot Vacuum has become an indispensable cleaning assistant, but their effectiveness depends on the condition of the filters. HEPA-The filter not only reduces the suction power of the 30-40%, This article provides detailed photo instructions on how to clean filters from different models (Mi Robot Vacuum-Mop). 2 Lite, Mi Robot Vacuum-Mop P, Mi Robot Vacuum-Mop 2 Pro, etc.), as well as hidden nuances, which are not written in the official manuals.

Many users make critical cleaning mistakes: washing HEPA-The filter is under running water (which destroys its structure), dryed with a hair dryer (the risk of deformation), or forgotten about the pre-filter, and we will take all the steps from dismantling to drying, and also tell you how often you need to clean the filters depending on the intensity of the cleaning. If your vacuum cleaner has become worse collecting dust, hums louder than usual or discharges quickly - the reason is most likely in the filters.

At the end of the article — FAQ answering frequent questions (can you use a vacuum cleaner without a filter than replace the original one) HEPA And the filter compatibility table for different Xiaomi models, don't miss the "hidden filter" section in some models, which is only cleaned by 10% of owners, although it is responsible for 20% of performance.

1.What filters are in the Xiaomi Mi robot vacuum cleaners and where they are located

In most models Xiaomi Mi Robot Vacuum installed two types of filters:

• 🔹 The main (preliminary) filter is a plastic or metal mesh that traps large debris (hair, wool, thread) located under the lid of the garbage container, just behind the turbine.
• 🔹 HEPA-filter (highly efficient) - captures fine dust (up to 0.3 microns), allergens and bacteria, located at the top of the dust collector, under a small plastic cover.

In models with wet cleaning function (Mi Robot Vacuum-Mop) 2 Pro, Mi Robot Vacuum-Mop P, can be an additional water filter that prevents dirt particles from entering the tank. 2-3 months), but you can not ignore: clogged filter leads to uneven spraying of water and divorces on the floor.

Mi Robot Vacuum-Mop 2 Lite and Mi Robot Vacuum 1S Use of a combined filter (preliminary) + HEPA It's cleaned whole, you don't have to disassemble it. E10 There is a "hidden filter" under the turbine - few people know about it, although it clogs faster than the main one.

2. When and how often to clean filters

The frequency of cleaning depends on the intensity of use and the type of coatings in the house:

Signs that it is time to clean the filters immediately:

• 🚨 The vacuum cleaner became louder (the turbine is overloaded).
• 🚨 The suction power has decreased (garbage remains on the floor).
• 🚨 There was an unpleasant smell after cleaning (accumulated bacteria).
• 🚨 Fast battery discharge (clogged filter increases engine load).

⚠️ Note: If you notice that the vacuum cleaner stops through 5-10 You're running a minute and you get a "Clean the filter" error, which means the filter is critically clogged, so you don't just have to clean it, you also have to check the turbine for hair wound onto the shaft.

3. Step-by-step instructions: how to properly clean filters

Before starting, it is mandatory:

• ⚡ Turn off the vacuum cleaner (button) ON/OFF case).
• ⚡ Take out the battery (if the model allows) or disconnect from the docking station.
• ⚡ Prepare: soft brush (dental or vacuum cleaner), dry cloth, vacuum cleaner with a narrow nozzle.

Step 1: Clean the main (preliminary) filter

1.Click on the opening button of the dumpster lid (usually located on top).

2. Take out the container and turn it over. The main filter is the net at the bottom.

3. Remove large debris with your hands (hair, threads). For fine dust, use a vacuum cleaner at minimum power or a brush.

4.If the filter is greasy (for example, after cleaning the kitchen), wipe it with a wet cloth soaked in soapy solution, then dry.

Step 2: Cleaning up HEPA-filter

1.At the top of the dumpster, find a plastic lid (usually labeled with a note). HEPA Carefully tuck it in with a nail or a flat screwdriver.

2. Get it out. HEPA-It looks like an accordion made of a special material (usually white or gray).

3. Do not wash under running water! Use a soft brush or vacuum cleaner at minimum power (keep the nozzle at a distance) 2-3 cm not to damage the fibers).

4 If the filter is heavily polluted, you can vacuum it on both sides or gently tap on a hard surface to shake off the dust.

Step 3: Clean the “hidden” filter (for models) E10, S10 etc.)

Some models have an extra filter mesh under the turbine that gets clogged with hair and dust to get to it:

1. Take the dumpster off.
2. And underneath, you'll see a circular turbine hole, and you'll see the plastic grille, which is attached to the latches, carefully.
3. Remove the trash with tweezers or brushes. Don't use sharp objects!

Step 4: Drying and Assembly

After cleaning, all filters must dry completely before being re-installed. Leave them dry for 24 hours (not on the battery or in direct sunlight!).

Install the filters in reverse order:

1. First. HEPA-filter (it should sit tightly in the grooves).
2. Then the main filter (check that the mesh is not bent).
3. Make sure all lids are closed before clicking.

⚠️ Warning: If the vacuum cleaner fails to turn on or gives an error, check if the filters are properly installed. 80% of the time, the problem is a loosely closed lid. HEPA-filter – the security sensor blocks the operation.

4.What can and can not clean the filters Xiaomi Mi

Use only these methods:

• ✅ Dry cleaning: soft brush, vacuum cleaner at minimum power, compressed air (cylinder).
• ✅ Wet cleaning (main filter only!): a cloth soaked in warm water with soap (no aggressive detergents!).
• ✅ Special wipes for equipment (for example, Xiaomi Mi Anti-Bacterial Wipes).

It is strictly forbidden:

• ❌ Wash HEPA-filter under running water - this destroys its microstructure.
• ❌ Use hot water (temperature above 40)°C deforms plastic).
• ❌ Dry with a hair dryer or on a battery - the risk of melting the frame.
• ❌ Clean with sharp objects (needles, knives) - you can tear the filter material.
• ❌ Apply alcohol, acetone, gasoline - they corrode glue and seals.

💡

If HEPA-filter is highly contaminated and not cleaned by brush, you can use a vacuum cleaner with a blow function (for example, Karcher). WD Direct the air stream from the back of the filter, which will help to dislodge dust from the deep layers.

5. How to prolong the life of filters: tips from service centers

Average service life of Xiaomi original filters — 6-12 months with proper care, to keep them working:

• 🔄 Clean the trash container regularly after each cleaning – this reduces the strain on the filters.
• 🔄 Use manual pre-cleaning (e.g., spotting large debris before starting the robot).
• 🔄 If there are animals in the house, clean the filters more often (wool quickly clogs cells).
• 🔄 Keep spare filters in a sealed bag - they are afraid of moisture.
• 🔄 Once every 3 months, wash the turbine (if the model is collapsible) - the accumulated dust there worsens suction.

Service engineers recommend a cleaning log: write down the dates of filter cleaning and consumable replacement, which will help track when it's time to buy new ones. HEPA-filter once every 2 weeks, and the suction power still falls - so it's time to replace it.

💡

Xiaomi’s original filters last longer than their counterparts but cost more. If you have a budget, choose certified substitutes (like Roborock Original Filter or Valetudo Filter).

6. How to choose and replace a filter: original vs analogues

Xiaomi’s original filters are labeled with the following articles:

• ZNMS17FM — For the Mi Robot Vacuum 1/1S;
• ZNMS19FM — For Mi Robot Vacuum-Mop 2 Lite/Pro;
• ZNMS20FM — For Mi Robot Vacuum-Mop E10/S10.

The cost of the original — 800-1500 roubles per set (main) + HEPA). Analogues are cheaper (300-800 ruble, but risks:

• 🛑 Poor quality of materials (HEPA may pass through).
• 🛑 A loose fit (the vacuum cleaner will give an error).
• 🛑 Fast wear (will have to be changed more often).

If you decide to buy an analogue, choose certified brands:

When replacing the filter:

1. Buy a kit (main set) + HEPA), Even if only one person has changed.
2. Before installation, check the sealing rubber bands - they should fit tightly.
3. After replacing, reset the counter in the Mi Home app (if there is such a feature).

7. Frequent mistakes and how to avoid them

Even experienced users make mistakes that shorten the life of a vacuum cleaner:

• 🚫 Ignoring the error "Clean the filter" → overheating.
• 🚫 Cleaning filters with wet wipes with alcohol → destructs the glue.
• 🚫 Installation of the inside-out filter" → The vacuum cleaner will not suck up dust.
• 🚫 Using a vacuum cleaner without filters → turbine will clog with dust 1-2 cleaning.
• 🚫 Storage of spare filters in the bathroom → moisture deforms.

If the vacuum cleaner does not start after cleaning:

1. Check if all the covers are tightly closed (security sensors can block work).
2. Make sure that the filters are installed correctly (HEPA-filter-mark TOP or).
3. Reset the vacuum cleaner: Hold the power button for 10 seconds.
