How to clean the filter of the robot vacuum cleaner Xiaomi: full instructions with photos and tips

Xiaomi’s vacuum cleaners have become indispensable cleaning aids, but their effectiveness depends on the condition of the filter elements. A filter clogged with dust and debris not only reduces suction power, but can also lead to engine overheating or sensor breakdowns. In this article, we will discuss how to properly clean the filter in Mi Robot Vacuum, MiJia, Dreame and other models of the brand to make the device work as new.

Many users make critical mistakes: washing HEPA-We'll tell you which filters you can wash and which you can vacuum, how often you clean, and what to do if you start collecting dust worse after cleaning. You will also find a table of compatibility of filters for popular models and answers to frequent questions.

Types of filters in Xiaomi robot vacuum cleaners: what are and what are different

Xiaomi devices use three main types of filters, each requiring a different approach to care:

• 🔹 Primary filter (prefilter) – a mesh or sponge insert that traps large debris (hair, wool, threads) usually located in front of the main filter and washed with water.
• 🔹 HEPA-filter - a highly efficient element that traps fine dust (up to 0.3 microns), allergens and bacteria. D9) Indelible (in most Mi Robot models).
• 🔹 Coal filter – absorbs odors, found in premium models (for example, Xiaomi Mi Robot Vacuum-Mop 2 Pro). Requires only dry cleaning or replacement.

It's important: HEPA-filter H11-H13 (Xiaomi's water-washing system is not allowed unless it's specified in the specific model instructions. The moisture destroys the microfibers, and the filter loses up to 70 percent of its efficiency.

How do you determine the type of filter in your robot? Look at the specifications of the model or examine the element visually:

• 📌 The first (or first) is the first (or second).
• 📌 Dense white or gray material with inscription "HEPA" — indelible.
• 📌 Black porous layer - coal (dry cleaning only).

When and how often to clean the filter: signs of contamination

The manufacturer recommends cleaning the filters after every 3-5 cleanings, but in practice the frequency depends on the operating conditions:

Indirect signs that the filter requires urgent cleaning:

• 🚨 The robot began to work louder (the load on the engine increased).
• 🚨 After cleaning, visible dust remains on the floor or carpet.
• 🚨 The Mi Home app will include Clean the filter or Weak Suction notifications.
• 🚨 The body of the robot overheats (you can check with your hand after 20-30 minutes of work).

⚠️ Note: If the robot vacuum cleaner Xiaomi has started to give the error Fan stuck or completely refuses to turn on, the cause may be not only the filter, but also a clogged turbine. In this case, you need a complete disassembly and cleaning of the fan – it is not recommended to do this yourself without experience.

Step-by-step: how to properly clean the filter of the robot vacuum cleaner

Before you start, disconnect the robot from the charging station and remove the battery (if the model allows), which will prevent accidental switching on during cleaning.

• 🧼 Soft brush (dental or for cleaning equipment).
• 💦 Warm water (not above 40)°C) and neutral detergent (e.g. dishwashing liquid).
• 🧻 Microfiber wipe or paper towels.
• 🔌 A vacuum cleaner with a narrow nozzle (for dry cleaning) HEPA).

Cleaning of the primary (net) filter

This filter can be washed with water:

1. Remove the filter from the case (usually it is behind the dumpster).
2. Wash under a weak stream of warm water, using a brush to remove the sticky dirt.
3. In case of severe contamination, soak for 10-15 minutes in a soapy solution.
4. Rinse and dry for at least 24 hours in a ventilated area (not on the battery!).

Cleanup HEPA-filter

For indelibles HEPA-filter:

1. Carefully vacuum the filter on both sides, holding the nozzle at a distance of 1-2 cm.
2. Use a brush to remove dust from the folds (move in the direction of the fibers).
3. In case of severe pollution, replace the filter (life is 6-12 months).

For flushables HEPA (Like in Dreame. D9):

1. Wash it under cool water without detergents.
2. Don’t rub or twist the filter – it will damage the structure.
3. Dry vertically for 12-24 hours.

Cleaning of the coal filter

The carbon filter can only be vacuumed or replaced, and washing with water destroys the adsorbent properties of coal.

• 🌬️ Once a month, dry the filter outdoors (for example, on the balcony) for 2-3 hours.
• 🌬️ Keep the robot in a dry place, avoiding humidity above 60%.

⚠️ Warning: Never use a hair dryer, microwave or battery to dry filters. High temperatures deform plastic elements and destroy the filter material. Optimal drying temperature is room temperature (20-25)°C).

💡

If after cleaning the filter still smells of dampness, put it for 1-2 hours in a sealed bag with soda - this will remove the smell and absorb the residual moisture.

Frequent Filter Cleaning Mistakes and How to Avoid Them

Even experienced users sometimes do things that shorten the life of the filters or make the robot inoperable. TOP-5 errors and their consequences:

• 🚫 Washing the indelible HEPA-filter → Loss of filtering ability, dust entering the engine.
• 🚫 Drying the filter with a phenome → melting of plastic fasteners, deformation of material.
• 🚫 Use of aggressive detergents (e.g. Domestos) → destruction of fibers, corrosion of metal parts.
• 🚫 Installation of a wet filter → short circuit, errors of humidity sensors.
• 🚫 Cleaning the filter with metal brushes → damage to microfibers, reduced efficiency.

How to avoid problems:

• ✅ Always check the label on the filter – if there is a Washable label, it can be washed.
• ✅ For cleaning, use only soft brushes (for example, a tooth with soft bristles).
• ✅ After washing, shake the filter to remove excess water, and dry in an upright position.

How to extend the life of the filter: tips from service centers

The average life of filters in Xiaomi robot vacuum cleaners:

• 🔄 Primary filter – 12-18 months (with regular washing).
• 🔄 HEPA-filter – 6-12 months (depending on the intensity of use).
• 🔄 Coal filter – 3-6 months (not subject to restoration).

To make the spenders last longer:

• 🌿 Use the robot at minimum power for daily cleaning (Quiet or Standard mode (Turbo/Max) quicker to clog the filter.
• 🌿 Clean the trash can after each cleaning – this reduces the load on the filter.
• 🌿 Set “cleaning areas” in the app, eliminating heavily dusty areas (such as carpets at the front door).
• 🌿 Once a month, wash the container for dust with soap – this prevents the appearance of bacteria.

Advice from the masters: if you use a robot for wet cleaning (moping model), after each such cleaning, dry the filter for 1-2 hours with the container lid open. HEPA 30-40%.

💡

Regular replacement of filters (even with visual cleanliness) - the key to long-term work of the robot. HEPA-The filter loses up to 50% of its effectiveness after 8-10 months of use, even if it looks normal.

Where to buy a replacement: original and compatible filters

The original Xiaomi filters can be purchased:

• 🛒 Official Mi Store (compatibility guarantee, but price is 20-30 higher%).
• 🛒 AliExpress (Look for sellers with a 98 rating%+ and reviews in Russian).
• 🛒 Marketplaces (Wildberries, Ozon, Yandex Market) – check the certificates of compatibility.

The cost of the original filters (2026):

Can you use non-original filters? Yes, but with reservations:

• ✅ Pros: the price is lower by 40-60%, often in the kit is 2-3 pieces.
• ❌ Cons: possible problems with the density of fitting, shorter service life, lack of certification HEPA.

⚠️ Warning: When buying compatible filters, check the size and shape — even a slight mismatch will lead to the suction of unfiltered air and overheating of the engine.
