How to remove the filter from the robot vacuum cleaner Xiaomi: instructions with nuances for all models

The filter in Xiaomi’s robot vacuum cleaner is like a human lung: if left untreated, the equipment will start to “gasp.” Dust, animal hair and microparticles clog the pores of the material, reducing the suction power by 30-50% after 2-3 months of active use, and 9 out of 10 users only clean the garbage container, forgetting about the filter – until the vacuum cleaner begins to buzz loudly or leave dust trails behind.

In this article, you will find step-by-step instructions for removing the filter from popular Xiaomi Mi Robot, Dreame and Viomi models, as well as how to wash, dry and when to buy a new one. We will analyze the typical errors that reduce the filter life by 2-3 times, and give tips for care, which the manufacturer does not always mention in the official manuals.

If your vacuum cleaner is getting worse at collecting garbage, making an uncharacteristic noise, or discharging quickly, it may be the filter that is to blame, and if it is contaminated, it increases the engine load, which leads to overheating and shorter battery life. D9) A clogged filter even blocks the start of the cleaning - the robot gives an error E3 or E5 And he refuses to work.

Unlike the garbage bag in conventional vacuum cleaners, the filter in Xiaomi robots requires regular cleaning - at least 1 time every 2 weeks for daily cleaning. But how to remove it correctly without breaking the latches? And can you wash the filter under running water? The answers are below.

1.Where is the filter in Xiaomi's robot vacuum cleaners?

Most Xiaomi models (including Mi Robot Vacuum-Mop 2 Pro, Dreame) D9, Viomi V3) The filter is hidden inside a dust collector, a plastic container where garbage gets into it, but its location may vary depending on the design:

🔹 Classical scheme (90% models): the filter is mounted on top of the dust collector, under a latched lid, visible immediately after the container is removed.

🔹 Models with a cyclone system (for example, Dreame) Z10 Pro: the filter is in a separate compartment next to the turbine, access to it is opened after removing the top panel.

🔹 Hybrid vacuum cleaners with wash function (for example, Xiaomi Mi Mop) 2T): The filter can be combined with or located under the water tank.

In order not to guess where to look, pay attention to the marking: on the body of the dust collector there is usually an arrow or an inscription. FILTER (on new models - a hieroglyph, which means "filtering grid»).

2. Step-by-step instruction: how to remove the filter from the vacuum cleaner

The process of removing the filter takes no more than a minute, but it requires care — especially if you're doing it for the first time. Don't pull the filter over the edge: this can break the sealing gum or break the plastic guides.

🔹 Step 1: Disconnect the vacuum cleaner from the charging station and turn it upside down with the vacuum collector. If the robot has just been working, wait 5-10 minutes - the hot air inside can warp the plastic when opened.

🔹 Step 2: Press a button or pull a latch on the back of the dust collector (usually marked by an arrow). V3) You need to move the lid to the left first, and then lift it up.

🔹 Step 3: Take out the dust collector and put it on a flat surface. If there's a lot of trash inside, don't shake the container, so the dust will get into the filter and clog it even harder.

🔹 Step 4: Find a filter -- it looks like a plastic cylinder or a rectangle with a fine mesh -- and gently pull it up and on you, holding it by the edges. If the filter is stuck, spin it slightly from side to side.

⚠️ Attention: In Dreame models D9 And the Xiaomi Mi Robot 2 filter is attached to the dust collector with magnetic latches, and if you pull it sharply, you can pull the seal off. The right way is to move the filter to the side first (counterclockwise), and then take it out.

Turn off the vacuum cleaner and let it cool down.

3. How to clean the filter: what can and can not be done

Cleaning the filter is not just rinsing under water, but the wrong wash can destroy the filter material and the vacuum cleaner will lose up to 70% of the suction power.

✅ We can:

💧 Wash with warm water (not hot! temperature up to 40)°C. Use a soft brush (e.g. toothbrush) or sponge without abrasive layer.

🧼 Use neutral detergents (liquid soap, dishware) Never use aggressive chemicals (bleach, vinegar, alcohol) - it destroys the micropores of the filter.

🌬 Dry naturally for 24 hours before re-installing.A hair dryer or battery warps the material.

❌ No:

🚫 Rubbing the filter with hard brushes - this tears the fibers and reduces filtration.

🚫 Squeeze or twist a wet filter - so spoils its shape.

🚫 Dry in the microwave or oven – even at low temperatures, plastic can melt.

🔹 Tip for severe contamination: If the filter is covered with sticky dirt (for example, after cleaning after repair), soak it for 10-15 minutes in warm water with the addition of baking soda (1 tbsp. spoon per liter.

💡

After washing, check the integrity of the sealing gum on the filter. If it cracks or loses its elasticity, it is time to replace the filter - otherwise dust will seep past it.

4.When the filter needs to be replaced, not cleaned

Even with perfect care, the filter in a robot vacuum cleaner is a consumable, and manufacturers recommend changing it every 6 to 12 months, but the actual duration depends on the intensity of use.

🔴 Visually:

📉 There are holes or gaps in the filtering grid.

🟤 The material has turned grey or brown (even after washing).

🔴 Functional:

🌀 Vacuum is worse sucking garbage, leaves dust on the floor.

🔊 Increased noise (whistling or humming).

⚡ Reduced battery life (due to increased engine load).

🔹 Wear test: Hold the filter to a bright light, and if rays penetrate it (as through gauze), then the pores are clogged irreversibly, and the filter passes the dust back into the air.

⚠️ Attention: In models with HEPA-Filters (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Pro) cannot be used inappropriately. Cheap alternatives often do not provide tightness, and dust bypasses filtration, getting directly into the engine.

5. Typical errors in handling the filter

Many users inadvertently spoil the filter after a couple of months, and here are the most common errors and their consequences:

🔹 Mistake 1: Cleaning the filter with a vacuum cleaner only

❌ What to do: Shake or blow the filter with a compressor without washing it.

⚠️ Consequences: Fine dust stays in the pores and cements, clogs them up forever. Suction power drops by 20 to 30 percent%.

🔹 Mistake 2: Installing a wet filter

❌ What to do: Put the filter back 1-2 hours after washing, without waiting for complete drying.

⚠️ Consequences: Wet material becomes a medium for bacteria and mold, and the smell of dampness that the vacuum cleaner carries around the apartment.

🔹 Mistake 3: Using household chemicals

❌ What to do: Wash the filter with Domestos, Whiteness or laundry detergent.

⚠️ Consequences: The aggressive agents break down the adhesive layer that holds the filter fibers together, and it starts to dust, throwing the microparticles back into the air.

🔹 Mistake 4: Ignoring the sealing gum

❌ What to do: Do not check the condition of the rubber seal at the edge of the filter.

⚠️ Consequences: Unfiltered air enters the engine through cracks in the rubber band, reducing its lifespan. In some models, this leads to an error. E4 («duct-clogging»).

6.How to prolong the life of the filter: tips from service centers

Employees of authorized Xiaomi service centers share life hacks that help save on replacing filters:

🔹 Advice 1: Preliminary cleaning of the dust collector

Before removing the filter, remove the bulk debris from the container with a mini vacuum cleaner or brush, which will reduce the strain on the filter the next time you clean it.

🔹 Advice 2: Alternative drying

To speed up the drying of the filter, place it on the refrigerator grille (there is good air circulation) or use the fan at the minimum speed (at a distance of 50 cm).

🔹 Advice 3: Protection from animal hair

If you have pets in the house, wipe the filter weekly with a dry wipe - the wool quickly clogs the pores. HEPA-filters (dreame) Z10 Pro) antistatic wipes can be used - they reduce hair adhesion.

🔹 Advice 4: Storage of a spare filter

Buy a spare filter and store it in a sealed bag. When the main filter is cleaned/dried, you can continue cleaning without interruption.

💡

Regular filter cleaning not only maintains suction power, but also reduces the energy consumption of the vacuum cleaner. According to Xiaomi, a robot with a clean filter spends 15-20% less battery power on the same cleaning area.

7.Where to buy the original filter for Xiaomi?

When buying a replacement, it is important to avoid counterfeits - they are often not suitable in size or are made of low-quality materials.
