Cleaning the vacuum cleaner Xiaomi V9: cleaning, cleaning and care of all knots

Xiaomi Mi Robot Vacuum-Mop V9 — It's a smart device that requires regular maintenance to keep cleaning as efficient as possible, and over time, its filters, brushes, and containers accumulate dust, hair, and small debris, which can lead to reduced suction power, navigational errors, or even breakage. In this article, we will discuss in detail how to properly clean all the elements of the vacuum cleaner so that it lasts longer and works without failures.

Many users make mistakes when cleaning, such as washing. HEPA-We'll tell you what parts you can wash and what you can wipe, how often you service and what tools you use. You will also find tips for eliminating common pollution problems and recommendations for choosing consumables.

If you're Xiaomi. V9 He's got a lot of trouble picking up garbage, making unusual sounds, or often stopping with a mistake, and he probably needs a deep cleaning, and then there's a step-by-step photo and video tutorial that will help even beginners cope with the task.

Preparation for cleaning: what will be needed

Before you start disassembling the vacuum cleaner, prepare everything you need to do to save time and avoid damage to the device, and here is the minimum set of tools and tools:

• ✅ Soft brush (for example, tooth or makeup brush) – to clean hard-to-reach places.
• ✅ Dry microfibre wipe - for cleaning the case and sensors.
• ✅ Cotton swabs - to clean narrow slits and contacts.
• ✅ Warm water and soap (preferably neutral, without aggressive surfactants).
• ✅ Hair dryer (optional) - for quick drying of filters.
• ✅ Screwdriver (cross, if you need to disassemble side brushes).

Do not use abrasive sponges, alcohol or solvents for cleaning, they can damage plastic parts and rubber seals. Also avoid direct water entering electronic components (sensors, buttons, connectors). If the vacuum cleaner is highly contaminated, you can use a vacuum cleaner - for example, a manual car to remove dust from internal cavities.

Before starting work, disconnect the vacuum cleaner from the charging station and remove the battery (if you plan to clean the internal parts), this will prevent accidental switching on and damage to the electronics, and we recommend taking photos of the disassembly process, so that you can properly collect everything back.

Cleaning of the main dumpster

The garbage can is the most polluted part of the vacuum cleaner, and it accumulates dust, hair, animal hair and other garbage, and if it is not cleaned in time, it can lead to clogs in the ducts and a decrease in suction power. Here's how to clean it properly:

1. Remove the container from the vacuum cleaner by pressing the lock button (usually located on the back of the case).
2. Throw the trash in the urn. If there's any hair or thread left inside, remove it manually or with tweezers.
3. Wash the container with warm water and soap. Citric acid (1 tbsp. per 1 liter of water) can be used to remove persistent contaminants.
4. Dry the container thoroughly before putting it back in. Humidity can cause mold to appear.

Notice the rubber seal on the container lid, which should be wiped with a wet wipe and greased with silicone grease (e.g., grease, WD-40 Specialist, so it doesn't crack over time, if the seal is damaged, it's better to replace it, otherwise the dust will seep back into the vacuum cleaner.

⚠️ Warning: Do not use hot water to wash the container, it can warp the plastic, and do not dry it in the microwave or battery.

Cleaning filters: HEPA and pre-cleaning

Filters in Xiaomi V9 They're responsible for trapping fine dust and allergens, and over time, they get clogged, and the vacuum cleaner starts to suck up air worse. V9 two filters installed:

• 🔹 Preliminary filter (net) - delays large debris.
• 🔹 HEPA-filter - traps particles up to 0.3 microns in size.

Cleaning the pre-filter can be carried out every 1-2 weeks, and HEPA-The filter needs to be replaced every 3-6 months depending on the intensity of use, but if you notice that the vacuum cleaner has become worse, the filters can be washed:

1. Remove the filters from the vacuum cleaner (they are under the lid of the garbage container).
2. Carefully tap the filters on a hard surface to remove dust.
3. Wash the pre-filter under running water. HEPA-filter can only be vacuumed or blown with compressed air (cannot be washed!).
4. Allow the filters to dry completely (at least 24 hours) HEPA).

If HEPA-The filter is highly contaminated and cannot be cleaned, it needs to be replaced. V9 You can buy it in the official store or on AliExpress (article: BHR4288GL preliminary and BHR4289GL for HEPA).

💡

If the vacuum cleaner is still not suctioning well after cleaning the filters, check if the duct is clogged between the container and the turbine.

Cleaning of brushes: main and side

Brushes are the most vulnerable part of a vacuum cleaner, because they are used to wrap hair, thread and wool. V9 There are three types of brushes:

• 🧹 Main brush (roller with bristles and rubber blades).
• 🌀 Side brushes (rotating, for cleaning along the walls).
• 🔄 Turbobrush (if included).

To clean the main brush:

1. Remove the brush from the vacuum cleaner by pressing the latches on the sides.
2. Remove the hair and threads from the roller, which can be done using scissors or a special cleaning tool (company with some models).
3. Wash the brush underwater if it is heavily contaminated. Do not use aggressive detergents.
4. Check the bearings on the shaft - if they catch, lubricate them with silicone lubrication.

The side brushes are easier to clean:

1. Remove the brush by pulling it down (sometimes a screwdriver is required to unscrew the mount).
2. Remove hair and debris from the axis of rotation.
3. Wipe the bristles with a wet napkin.

⚠️ Note: If the side brush does not rotate after cleaning, check if the debris has entered the drive mechanism. Also make sure that the brush is properly installed - it should be easy to swipe with the hand.

If the bristles on the brushes are worn or broken, they should be replaced. V9 articulate BHR4290GL, and the main brush — BHR4291GL.

Cleaning sensors and sensors

Sensors are responsible for navigation, obstacle detection and height control. If they are contaminated, the vacuum cleaner can become unmanageable, bang against furniture or fail to see the charging station. V9 There are several key sensors:

• 👁️ Lidar (laser rangefinder) - responsible for building a room map.
• 📏 Anti-fall sensors (under the bottom) – prevent falling from the stairs.
• 🔦 Infrared sensors detect obstacles.
• 🔋 Charge sensor – monitors the level of the battery.

To clean the sensors:

1. Wipe the lidar (glass lens on top of the vacuum cleaner) with a dry microfiber wipe. Don't push hard!
2. Clean the anti-fall sensors with a cotton swab dipped in alcohol (only for glass surfaces).
3. Blow infrared sensors with compressed air (for example, a canister for cleaning equipment).
4. Check the contacts of the charging station and vacuum cleaner – they should be clean and not oxidized.

If after cleaning the vacuum cleaner still poorly navigated, try to reset the map of the room in the application Mi Home:

Open the application → Select a vacuum cleaner → Settings → Map → Reset the card

You can also calibrate the sensors:

Place the vacuum cleaner on a flat surface → Press the buttons “Home” and “Spot” for 5 seconds → Wait for the sound signal

Cleaning turbines and ducts

If the vacuum cleaner is getting worse, but the filters and the container are clean, the problem may be in the turbine or the ducts, and over time, dust accumulates that interferes with the normal operation of the fan, to clean the turbine:

1. Remove the garbage can and filters.
2. Unscrew the screws on the bottom cover of the vacuum cleaner (a cross screwdriver will be required).
3. Carefully remove the lid to access the turbine.
4. Remove dust from the turbine blades with a soft brush or vacuum cleaner.
5. Blow the air ducts with compressed air.

Be careful not to touch the turbine blades with your hands, as they are sharp, and do not use wet wipes to clean electronics, and if the turbine is heavily contaminated with oil or sticky dirt, you can wipe it with a napkin soaked in isopropyl alcohol.

Once cleaned, put the vacuum cleaner back together, make sure all the mounts are tightened and the seals are in place, and if the vacuum cleaner makes unusual noises after assembly, check if the debris has been re-entered into the turbine.

💡

Cleaning the turbine is the hardest part of the maintenance, and if you're not confident in your abilities, you should go to the service center to avoid damaging the engine.

Care for a mop and water tank (if any)

If you have a Xiaomi model V9 It supports wet cleaning, and in addition to the dust collector, it has a water tank and a mope nozzle, and you also need to clean them regularly, otherwise you may get mold or lime plaque on the fabric.

To clean the mop system:

1. Remove the water tank and pour out the remaining liquid.
2. Rinse the tank with warm water. If there is a plaque, use a solution of vinegar (1:1 with water).
3. Remove the mope nozzle and wash it by hand with soap. Don't use the washing machine!
4. Dry all the details in the air (at least 4-6 hours).

If the mopose cloth has worn or become stiff, it needs to be replaced.Original wipes for Xiaomi V9 articulate BHR4292GL. You can also use universal microfiber wipes, but they must be without pile so as not to clog the pump.

If the vacuum cleaner has stopped moisturizing the floor, check:

• 💧 Cleanliness of tubes and nozzles (clean with a needle).
• 🔋 Pump operation (when switched on, a slight hum should be heard).
• 📱 Settings in the application (water supply level).

Frequent Mistakes and How to Avoid Them

Many users make mistakes when cleaning Xiaomi V9, And that's what causes breakdowns or disruptions:

• 🚫 Washing HEPA-filter - this destroys its structure, and it stops trapping fine dust.
• 🚫 Use of aggressive detergents – they can damage plastic and rubber seals.
• 🚫 Cleaning the vacuum cleaner in the on state is dangerous and can lead to a closure.
• 🚫 Ignoring side brushes - hair is wound on them, which leads to overheating of the engine.
• 🚫 Drying parts with a hair dryer at high temperature - this deforms the plastic.

And many people forget about regular replacements, and here's the recommended timeline:

If you notice that the vacuum cleaner has become more often stopped with an error (for example, code 10 is a problem with the wheel or 5 is a jamming of the brush), first check the purity of all moving parts.
