How to remove the filter on the robot vacuum cleaner Xiaomi

Modern cleaning devices, such as the Xiaomi Mi Robot Vacuum or Roborock, have become an integral part of the smart home, greatly simplifying the life. One of the key elements of the filtering system is HEPA-A filter that traps the smallest particles of dust, allergens and animal hair, and over time, this component gets clogged, which leads to a decrease in suction force and can cause errors in the operation of pressure sensors.

Many owners experience a situation where the robot starts making strange sounds, loses power or reports an error through the app. Often the root of the problem lies in a contaminated filter element that requires immediate cleaning or replacement. In this article, we will discuss in detail how to properly remove, clean and, if necessary, replace the filter in various models of Xiaomi vacuum cleaners to make the device work as new again.

Don’t ignore the clogging signals, as constantly working with a clogged filter puts an excessive load on the engine, which can lead to its premature failure.Proper maintenance ensures not only clean floors, but also a long life of your robot assistant.

Diagnosis: when to remove and clean the filter

Understanding when to intervene in the filtration system helps avoid serious breakdowns. Xiaomi and Roborock have a smart monitoring system that tracks the air pressure in the dust container, and if the airflow is difficult, the smart algorithm signals it to the user.

Note the following signs that indicate that it is time to remove the filter and put in order:

• 📉 Robot vacuum cleaner began to suck up garbage worse, leaving dust in corners or on carpets.
• 🔊 The device makes a louder, whistling or humming sound while working.
• 📱 In the Mi Home or Roborock app, a notice appears to indicate the need to clean the dust container or check the filter.
• 🌪️ From the blowing hole begins to fly out fine dust instead of clean air.

The frequency of maintenance depends on the operating conditions. If you have pets or carpets at home, you will have to check the condition of the filter more often. On average, preventive cleaning is recommended every 1-2 weeks, and a complete replacement of the element is done every 2-4 months.

⚠️ Warning: Ignoring filter clogging warnings can cause motor overheating and permanent battery life loss due to increased power consumption.

Some users mistakenly believe that if the dust container is empty, the filter is clean. It's not. The fine dust quickly clogs the pores of the filter material, making it impermeable to air, even if it appears relatively clean visually.

Filters in Xiaomi and Roborock devices

Before you start dismantling, it’s important to understand what kind of filtration you’re dealing with. Xiaomi engineers use different solutions depending on the device series and year of release.

In modern models, the most common is a multi-stage system: the primary layer traps large debris, and the main unit is responsible for fine air cleaning. Let's look at the main types that you can find inside your gadget:

• 🟢 Washing HEPA-filters: They are corrugated, often enclosed in a plastic or rubber frame, designed for repeated washing with water, but require careful drying.
• 🟡 Combined filters: Consisting of a mesh prefilter and a main filter HEPA-And often, in these models, you don't want to separate them, you clean the entire module.
• 🔴 Disposable filters: These are found in some budget or older models, have a paper base that breaks down when in contact with water, and must be replaced after filling.

You can tell the type of filter you have by labeling on the case or in the instructions. If you have a tap icon or droplet on the element, you can wash it. If the material resembles dense paper or fabric without a rigid frame, you should limit yourself to dry cleaning or replacing it.

It's also important to note the differences in attachment, where in some models the filter is simply inserted into the slots of the container, in others it is fixed with a special lid or magnetic grid, and be careful when you look, so as not to use excessive force.

Step-by-step: how to remove and clean the filter

The process of removing the filter element is simple enough, but requires care so as not to damage the plastic latches or the filter material itself. Below is a universal instruction, suitable for most Xiaomi and Roborock models.

First, you need to access the dust container, flip the robot vacuum cleaner upwards or open the top cover, depending on the design of your model, and carefully remove the dust collector by pressing the lock and pulling it upwards.

On the top of the container, you'll see the filter compartment cover, which usually has a characteristic texture or gripper, and press the lock (if you have one) and lift the lid, and inside you'll see the filter element itself.

To remove the filter, grab a special plastic handle or tongue located on the end. Smoothly pull the element up. If the filter is sitting tight, sway it slightly from side to side, but do not pull sharply so as not to tear the thin material.

Now we're going to clean up. HEPA-filter, knock on the edge of the sink to remove the bulk of the dry dust, then rinse it under a stream of warm water, the water pressure should be moderate, direct the jet against the direction of suction (on the clean side inwards).

⚠️ Attention: It is strictly forbidden to use brushes, sponges or detergents for cleaning. HEPA-Mechanical action will destroy the microscopic fibers, and the filter will lose its properties.

After washing, shake the water thoroughly and leave the filter to dry horizontally in a warm, well-ventilated place. The drying process takes at least 24 hours. Using a wet filter is unacceptable - this can lead to water entering the engine and the appearance of an unpleasant odor.

If your filter is not designed for washing, use a soft dry brush to remove dust from the surface. Carefully walk along the bristles, trying to knock out dust from the depths of the material.

Comparison of cleaning and maintenance methods

The choice of maintenance method depends on the type of contamination and the design of the specific element, and to make it easier for you to navigate, we have prepared a comparison table that will help you make the right decision on how to care for your device.

As you can see from the table, pre-filters (usually fine mesh) are the most resistant to mechanical cleaning, and can be washed neatly with a soap and brush if they are heavily contaminated with fatty plaque (relevant to studio kitchens). HEPA-The block requires much more delicate handling.

Some users try to extend the life of the filter by knocking it out, and you can only do this over the trash can and very carefully, and excessive mechanical exposure causes the filter to start letting the dust back into the room, negating all the work of the air purification system.

💡

To remove the old dust from the dry filter folds, you can use a compressed air can to clean the electronics. Blow the filter from the inside out.

Regular maintenance not only preserves suction power, but also ensures hygienic cleaning, and a clogged filter becomes a breeding ground for bacteria and a source of unpleasant odor that spreads throughout the house while the robot is running.

Frequent errors in the maintenance of the filtration system

Even experienced users sometimes make mistakes that can cost a device health, and let’s take a look at the most common misconceptions and missteps that occur when servicing Xiaomi robots.

The first and most dangerous mistake is to install a wet filter, and many users rush to put the dry element back in place, and the moisture instantly turns the compressed dust into mud, which clogs the pores, and the moist environment is ideal for mold reproduction.

The second mistake is the use of inappropriate cleaning products: washing powders, laundry conditioners, or aggressive chemistry can destroy the structure of the filter material or leave a chemical odor that will be blown out by the robot.

• ❌ Battery drying attempt: High temperature deforms plastic and synthetic fibres.
• ❌ Using a vacuum cleaner to clean the filter: A powerful airflow from a conventional vacuum cleaner can damage the thin structure HEPA Or simply ineffectively knocking out deep dust.
• ❌ Ignoring sensors: If a robot says “clean the filter” and you just turn off the notification, the problem won’t go away.

⚠️ Warning: Never use the filter after contact with water unless it is designed for washing.The paper base will swell and lose shape, stopping air flow.

And it's also worth mentioning the savings error: some owners try to wash disposable filters in the hope of saving money, and as a result, the filter breaks or loses properties after a couple of cycles, and the risk of engine damage remains high, and it's better to buy an original consumable or a quality equivalent.

💡

Compliance with the rules of drying and rejection of aggressive chemistry is the key to the long service of the filtration system of your robot vacuum cleaner.

What to do if the robot continues to make a mistake

There are times when you clean or replace the filter, but the Xiaomi robot vacuum cleaner still reports an error or shows low suction power, in which case the problem may lie not in the filter itself, but in adjacent systems.

First of all, check the pressure sensor, which is located inside the main unit of the robot, where the container is inserted, which may have settled on dust, carefully blow the sensor hole or wipe it with a dry cotton swab.

Also worth checking is the tightness of the assembly. Make sure the dust container cover is closed before the click and the container itself is properly installed in the robot. If the sealing gum on the filter or lid is damaged or lost, the air will be sucked bypassing the filter, and the sensor will show an error.

If simple methods didn’t work, try resetting or restarting your device. Sometimes a software failure can fix an error even when everything is physically clean. Press the on and off buttons for 10-15 seconds at the same time (the combination may vary depending on the model).

In rare cases, you need to change the sensor itself or check the engine turbine for foreign objects. If you suspect a mechanical failure, you should contact an authorized service center.
