Replacement of the filter in the vacuum cleaner Xiaomi V9P: the complete guide

Xiaomi’s wireless vacuum cleaners have earned a reputation for being reliable cleaning assistants, but their effectiveness depends on the state of the filtration system. Xiaomi V9P (often known as the Deerma VC20 Pro or similar modifications depending on the region) is equipped with an advanced cyclone cleaning system, but even the most powerful motor will not be able to maintain high suction if the filter elements are clogged with dust. Regular maintenance is not just a recommendation, but a necessity for saving the engine life.

Many users experience a situation where the device starts to buzz louder than usual, battery life is reduced, and the exhaust hole appears unpleasant odor or fine dust. These symptoms often indicate that it is time to replace consumables. In this article, we will discuss in detail the replacement process, the differences between filter types and nuances that are rarely written about in official manuals.

Proper care of the filtration system guarantees not only cleanliness in the house, but also safety for allergic people, since it is the cleanliness of the house. HEPA-The filter traps microscopic particles. Ignoring replacement times can cause the engine to overheat and cause an expensive component to fail. Let's take a look at how to properly service your Xiaomi. V9P, to serve for years to come.

Symptoms of clogging and timing of replacement of consumables

You can see that the filter in your Xiaomi V9P needs to be replaced by a number of indirect signs that appear during operation. First of all, pay attention to the nature of the sound of the engine: if the tone has become higher and piercing, this indicates that air is barely passing through the filtration system, the motor begins to work with increased load, trying to compensate for lost traction.

The second important indicator is the visual state of the outflow, and if you notice a slight haze or smell dust when you're working at maximum power, the HEPA filter is damaged or critically clogged, and it's also worth remembering that even with regular brushing, the fibers of the material degrade over time and stop trapping small particles.

The manufacturer recommends changing the main HEPA-filter-in 3-6 The pre-motor sponge (pour element) can be washed and reused, but it also has a resource of approximately 6-12 months.

⚠️ WARNING: If you use a vacuum cleaner to clean construction dust, chalk dust or plaster, the service life of the filters is reduced in the 3-4 In such cases, replacement is required immediately after completion of the work, regardless of the visual condition.

It's important to distinguish between types of contaminants. Regular house dust is laid on the surface in a smooth layer, whereas animal hair can penetrate deep into the filter structure, clogging the pores. Visual inspection does not always give a complete picture, so also focus on the date of the last replacement.

Types of filters in the Xiaomi V9P system

The V9P air purification system is multi-stage, which provides high efficiency with low noise. Understanding the design will help you service each element correctly. There are two main filter elements here, and they perform completely different functions.

The first barrier to dust is the pre-motor sponge, which is a porous material, usually black or gray, that is put directly on the inlet of the engine block. Its task is to trap large fractions of dust, pile and hair, preventing them from getting on the turbine blades and into a thin structure. HEPA-This element can be washed and dried, which prolongs its life.

The second and most important element is HEPA-The filter is in the Xiaomi model. V9P It's often made in a cylinder or a cone with corrugated paper, and it's responsible for cleaning the air and retaining allergens, pollen and bacteria. Unlike a sponge, this filter cannot be washed, as the water destroys the structure of the paper and adhesive base, after which the filter turns into a useless mass.

• 🌪️ Premotor sponge: protects the engine from large dust, subject to regular washing.
• 🦠 HEPA-filter: provides fine cleaning of exhaust air, requires periodic replacement with a new one.
• 🛡️ Protective grid: metal frame that protects corrugated HEPA-filter for mechanical damage during installation.

Some users are trying to wash HEPA-But if you have a wet filter, you have a lot of resistance to air, and you can overheat the engine. HEPA-filter, it must be completely dried during the 24-48 hours, but it is better to replace it with a new one to avoid mold inside the body.

Preparation for replacement: tools and conditions

The process of replacing filters in Xiaomi V9P does not require complex tools or special skills, but requires compliance with certain conditions. The most important rule is that all manipulations should be carried out with the vacuum cleaner switched off and disconnected from the charger, this will eliminate accidental start of the engine and injury to the fingers.

You don't need a screwdriver or tweezers, because the dust container and engine block are designed for quick access, but before you start, you should prepare the workplace, cover the table with clean rags or paper, so that the new part does not get dirty immediately after being removed from the package.

You also have to buy some original consumables or quality ones in advance, and there are many fakes on the market that can fit loosely into the body, passing dust past the filter directly into the engine, and pay attention to the density of the corrugated gum and the quality of the sealing gum at the base of the filter.

• 🧤 Clean hands: it is advisable to work in clean gloves or with thoroughly washed hands, so as not to bring fat and dirt to the new filter.
• 🗑️ Garbage bin: to dispose of an old, dusty filter so that dust does not spread around the room.
• 🧹 Dry cloth: to wipe the interior walls of the container before installing new components.

If you're changing the filter for the first time, it makes sense to take a picture of the original position of the parts before disassembling. While the design of the V9P is intuitive, photography will help avoid assembly errors, especially in the orientation of the sealing rings.

Step-by-step instructions: dismantling and installation

The replacement process itself can be divided into several successive steps: strict adherence to the procedure ensures that you do not damage anything and assemble the device correctly, starting with the removal of the dust container.

Press the unlock button of the dust collector bowl and remove it from the main unit. Turn the bowl upside down. You will see that the bottom part (cyclone block) is attached to the top cover using latches or threaded connections, depending on the specific V9P revision. Carefully disconnect these parts.

Then you take out the old filter, which is in the middle of the cyclone block, and you grab the plastic base or the filter handle and you pull it up, and if the filter is sitting tight, you can sway it slightly from side to side, and you can do it without putting too much effort into breaking the plastic guides.

Now, notice the pre-motor sponge, which is located on the engine block itself, which separates from the handle, remove the engine compartment cover (usually held on magnets or latches), and carefully pull the old sponge off the turbine inlet, and if it's heavily contaminated, it can be washed with water, but you can only install it back in a completely dry sponge.

The new filter is installed in reverse order. HEPA-the socket until the characteristic click or stop. Make sure it sits smoothly and without skewing. Put a clean and dry foam sponge on the motor entrance, spreading it around.

⚠️ Attention: When installed HEPA-Make sure that the edges of the filter don't turn around, and any gap between the filter and the body will cause the untreated air to leak out and the motor to fail quickly.

After all the components are assembled, run a test run, turn the vacuum cleaner on at minimum power and listen. If there is no foreign whistling sounds and the traction is restored, then you did everything right.

Cleaning and maintenance of adjacent nodes

Replacing the filter is a great reason to conduct a complete revision of other components Xiaomi V9P. While the vacuum cleaner is disassembled, be sure to check the condition of the brush of the main shaft. It often winds hair and threads, which create additional resistance and can tear the drive belt or overload the brush motor.

Clean the ducts inside the handle and the connecting tube. They often form dust clumps that harden over time and block the flow of air. It is convenient to use a long brush for cleaning or simply shake the tube above the garbage can.

Special attention should be paid to the dust sensor (if it is included in your modification), its optical window should be wiped with a dry soft cloth, the dust plaque on the sensor distorts the readings, and the vacuum cleaner may incorrectly switch power modes.

Remember, the battery, although it doesn't need to be replaced as often as the filters, the contacts on it and in the handle should be wiped periodically with an alcohol wipe to ensure good contact, and oxidation of the contacts can lead to false discharge indications.

• 🔋 Battery Contacts: Wipe dry cloth to improve conductivity.
• 🌪️ Air ducts: Remove stuck lumps of dust and wool.
• 👁️ Sensors: gently clean the optics of the dust sensor with a dry wipe.

A comprehensive maintenance approach will extend the life of the device by several years.The Xiaomi V9P vacuum cleaner is designed with the expectation of ease of maintenance, so don’t ignore these simple procedures.

Comparison of original and compatible filters

There are many smart-tech supplies in the market, and users often have to choose between buying an expensive Xiaomi original or a more affordable one, and to help you decide, we've created a comparison table.

The original filters undergo strict quality control and are guaranteed to match the aerodynamic characteristics of the V9P model. The use of cheap analogues can lead to the fact that the vacuum cleaner will work louder and the efficiency of cleaning will decrease.

But there are proven third-party manufacturers that make compatible accessories of decent quality. If you choose an analog, read reviews carefully and pay attention to the thickness of the filter walls. Too thin filter will clog faster and can let dust into the engine.

Savings on filters often come off sideways, as engine repairs cost 30-50% of the cost of a new vacuum cleaner, so it is better to overpay for a quality consumable than risk the main unit of the device.

💡

Buy filters in sets (3-5 pieces) that are cheaper and you will always have a year's supply even if the current model disappears from sale.

Frequent errors in service

Even experienced users sometimes make mistakes that negate all the care efforts of the appliances. One of the most common mistakes is installing a wet filter. As mentioned, moisture inside the case is a way to short circuit and corrosion of the contacts.

Another mistake is to use aggressive chemistry to wash the sponge. Alkaline or acidic agents can break the structure of the foam, making it brittle. Use only warm water and, if necessary, soft soap, thoroughly washing the foam.

Some users are trying to “reanimate” the old HEPA-It's not effective, because fine dust clogs the pores dead, and after cleaning it, the filter will still not let air through at the desired speed.

⚠️ Warning: Never turn on the vacuum cleaner if the filter is installed incorrectly or is not available.This can lead to the absorption of large objects into the turbine and its mechanical destruction.

Avoid storing spare filters in wet areas such as a bathroom or balcony. Paper and synthetic fibers are hygroscopic and can draw moisture from the air, which will worsen their properties even before installation.

Following these simple rules will allow you to avoid typical problems and enjoy clean cleaning.Remember that the Xiaomi V9P is a smart device that requires careful, but not complicated, maintenance.

💡

Regular replacement of the filter (every 3-4 months) keeps the suction power at the level of 95-98% of the factory and extends the engine life by 2 times.
