How to clean the filter of the robot vacuum cleaner Xiaomi: a complete guide with photos and tips

Xiaomi vacuum cleaners have become an integral part of smart homes, but their effectiveness depends on the state of the filter elements. 30-40%, But it can also cause the engine to overheat or the sensors to break down. HEPA-filters under running water, dry them with a hair dryer or ignore replacement until the smell of burning.

In this article, we will look at all types of filters in Xiaomi robot vacuum cleaners (including Mi Robot Vacuum, Viomi, Dreame models), learn how to clean them properly and determine when to buy a new one. We will focus on the hidden consequences of improper care, from shortening battery life to the risk of fire due to overheating.

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

Xiaomi’s lineup uses three main filter types, and each requires a different cleaning approach. A type-determining error can cause permanent damage, such as washing. HEPA-The filter in the washing machine destroys its microstructure, and neglect of cleaning the prefilter accelerates the wear of the turbine.

To identify the filter, remove it from the vacuum cleaner and compare it to the descriptions below:

• 🔹 Prefilter (rough cleaning) - a mesh or spongy element that traps large debris (hair, wool, grains of sand) located in front of the main filter. Models: all versions of Mi Robot Vacuum, Viomi V2/V3.
• 🔹 HEPA-filter (fine cleaning) - folding "accordance" material that traps particles to 0.3 microns (pollen, bacteria) Marking: HEPA H11/H12/H13. Models: Dreame D9, Xiaomi S10+.
• 🔹 Coal filter - combined (HEPA + Activated carbon to neutralize odors. HEPA, But with a black layer. SE, Mi Robot Vacuum-Mop 2 Pro.

If you are not sure about the type of filter, check the documentation or use the model compatibility table below. Importantly, carbon filters can not be washed - only vacuumed or replaced!

Cleaning frequency: how to know if the filter is clogged?

The manufacturer recommends cleaning the filter after every 3-5 cleanings, but this interval varies depending on the conditions. For example, in a house with animals or during repairs, the filter can be clogged 2 times faster.

• ⚠️ Decrease in suction power - the vacuum cleaner begins to "tumbling" on the carpets.
• ⚠️ Sensor errors – the robot loses orientation due to overheating of electronics.
• ⚠️ The appearance of the smell - decaying organic matter in the filter emits a putrid aroma.

Critical pollution can be determined by 4 signs:

1. The robot emits an uncharacteristic hum (the turbine works with a load).
2. Cleaning time has increased by 20% or more.
3. On the body of the vacuum cleaner after work remains a dusty raid.
4. The mobile application appears a notification "Check filter".

💡

If the robot has started avoiding carpets or often stops for rest, check the filter first, which solves the problem in 80% of cases.

Step-by-step: how to clean the filter correctly

The cleaning process depends on the type of filter, but there are universal rules:

1. Always disconnect the vacuum cleaner from the charging station before removing the filter.
2. Use a soft brush (such as a toothbrush) or vacuum cleaner with minimal power.
3. Avoid abrasive materials (metal sponges, sandpaper).

Further, detailed instructions for each type:

Cleaning of the prefilter (net/sponge)

This filter can be washed, but with caution:

Vacuum filter on both sides|Wash under warm water (max 40)°C)|Do not use detergents|Drying naturally for 24 hours|Before installation, check for integrity-->

⚠️ Warning: If the prefilter is deformed or broken, replace it. The damaged element lets the large debris into the main filter, reducing its life by 3 times.

2. Cleanup HEPA-filter

HEPA-filters cannot be washed, only vacuumed or blown back (e.g., a dryer in cold-blown mode:

1. Remove the filter, carefully fold the "accordance" to access the folds.
2. Vacuum on both sides with a soft pile nozzle.
3. For deep cleaning, use a compressor with a pressure of no more than 2 bar.

If the filter is covered with a sticky coating (for example, after cleaning the kitchen), use a dry microfiber wipe soaked in a solution of water and vinegar (1:1). Don't rub! - only wet movements.

Caring for the carbon filter

The carbon layer can't be reconstituted, it can only be replaced, but the outer part (HEPA) is cleaned as described above. The carbon filter life is 3-6 months with heavy use.

Compatibility table: filters for popular Xiaomi models

Use this table to find a replacement or to specify the type of filter for your model:

For older models 2019 Years (e.g. Mi Robot Vacuum) 1) The original filters can be discontinued, and then the Roborocks will work. RR-FILT-001, RR-FILT-002) universal HEPA-filter-marked H11/H12.

Common Mistakes and How to Avoid Them

Even the most experienced users make mistakes that shorten the life of a filter or vacuum cleaner. TOP-5 fatality:

• 🚫 Washing. HEPA-filter in the washing machine - destroys the fibers, after which the filter passes up to 70% of the dust.
• 🚫 Drying with a hair dryer or on a battery - high temperatures deform the filter frame, and it ceases to fit tightly.
• 🚫 Use of household chemicals - even "sparing" detergents leave a film that clogs pores.
• 🚫 Installation of a wet filter - leads to corrosion of the vacuum cleaner contacts and short circuit.
• 🚫 Ignoring cracks in the filter body - through them, the dust gets directement into the engine.

Especially dangerous mistake. №2: The superheated filter can melt inside the vacuum cleaner, blocking the turbine. 50-70% cost of a new robot.

⚠️ Warning: If the vacuum cleaner starts to make a whistling sound after cleaning the filter, turn it off immediately! This is a sign that the filter is installed incorrectly and the air is bypassing, risking damage to the turbine blades.

When to change the filter: 5 signs of wear

Even with perfect care, filters have a limited resource, manufacturers specify a lifetime in months, but the actual wear depends on the intensity of use.

1. Visible damage: ruptures, deformation of the frame, shedding of the coal layer.
2. Persistent smell after cleaning, even if the garbage container is empty.
3. Increased charging time – a clogged filter makes the engine run at its limit, consuming more energy.
4. The “Fan stuck” error in the application is a signal of critical resistance to airflow.
5. Dust at the exit: put your hand to the exhaust hole of the vacuum cleaner - if you feel the flow of warm air with particles, the filter lost its effectiveness.

For models with laser sensors (for example, the Viomi V3), a worn filter can cause false alarms of the anti-stuck system.

💡

The average life of filters in Xiaomi robot vacuum cleaners: pre-filter — 12 months, HEPA — 6-10 months, coal — 4-6 months. Exceeding these deadlines leads to irreversible failure of the equipment.

Alternative solutions: can you do without the original filters?

Xiaomi’s original filters cost between 800 and 2,500 rubles, which forces users to look for analogues, but not all substitutes are equally useful.

• ✅ Certified analogues (e.g. from Roborock or Ecovacs) – suitable if the size and class of filtration match (HEPA H11/H12).
• ⚠️ Universal. HEPA-filters - may not fit tightly, passing dust past.
• ❌ Homemade filters made of improvised materials (gazette, batting) - do not provide the required degree of cleaning and can catch fire from the engine spark.

If you want to save money, choose metal framed analogs, which last longer.

1. Compatibility of the model article (see table above).
2. The presence of sealing rubber at the edges.
3. Reviews of the real life (some cheap filters are "blown away" in 2 months).

⚠️ Note: Using uncertified filters voids warranty on robot vacuum cleaner. Xiaomi service centers check this by serial number of components.
