Before disassembling the vacuum cleaner, prepare everything you need. Incorrect cleaning can cause sensors to break or water to enter electronic components, so it is important to maintain consistency and use only authorized means.

You will need to:

• 🧴 Soft brush (a toothbrush or makeup brush is suitable) - for cleaning brushes and hard-to-reach places.
• 🧽 Microfiber cloth - for cleaning the case and sensors.
• 💧 Warm water (not hotter than 40)°C) for washing containers and filters.

⚠️ Attention: If your Xiaomi V9 It's equipped with a wet cleaning function, so never wash the water tank in the dishwasher, and the plastic can deform, and the tank will not close tightly, leading to leaks.

Cleaning of the dust and garbage container

The container is the heart of the vacuum cleaner, and clogging causes a loss of suction power. In the Xiaomi V9, it consists of two parts: a main compartment and a fine mesh that traps fine dust. If the mesh is not cleaned, it clogs and lets debris into the filters, which shortens their lifespan.

Step-by-step:

1. Remove the container by pressing the release button on the back of the vacuum cleaner.
2. Remove large garbage manually (do not shake it off over the urn - the dust will fly away!).
3. Wash the container with warm water with neutral detergent. Use a brush for hard-to-reach areas.
4. Pay special attention to a fine mesh - it must be washed under a stream of water, gently rubbing with your fingers.
5. Dry all the parts in the air for at least 4-6 hours, using a vacuum cleaner with a wet container will lead to mold.

If the net is heavily contaminated and not washed, you can soak it in warm water with soda (1 tbsp. per 1 liter of water) for 10-15 minutes. Do not use vinegar or citric acid - they can damage the plastic.

3. Cleaning and replacement of filters: HEPA and pre-filters

Filters in Xiaomi V9 — It's the most vulnerable element. HEPA-The filter retains up to 99.97% of the fine particles, but if left uncleaned, it becomes a breeding ground for bacteria and a source of bad smell. HEPA Large waste, but also requires regular cleaning.

How to Clean the Filters Correctly:

• 🔄 Pre-filter (gray, spongy): rinse under warm water without detergents, slightly squeeze (don't twist!) and dry. You need to change it once in a while. 3-6 months.
• 🌬️ HEPA-filter (white, folded): you can't wash it with water! Clean it only dry, with a soft nozzle vacuum cleaner or a brush. Change it once in a while. 6-12 months.

If HEPA-The filter is wet, don't dry it with a hair dryer, high temperatures will destroy the microfibers, let it dry for 24 hours at room temperature, if the filter has deformed or lost its stiffness, it needs to be replaced.

⚠️ Attention: In Xiaomi models V9 wet-cleaning HEPA-The filter may have a hydrophobic coating, and if you accidentally wet it, check the integrity: bring it to the light, if you see the gaps, the filter must be replaced.

4. Cleaning of brushes: main and side

Xiaomi V9 brushes are magnets for hair, thread and wool. If not cleaned, the coiled hair blocks rotation, and the vacuum cleaner starts to bounce or leave unharvested areas. The turbobrush (main) requires cleaning after each cleaning, the side can be cleaned every 2-3 uses.

How to clean and clean a turbobrush:

1. Press the latches on the sides of the brush and remove the lid.
2. Remove the shaft with bristles - gently pull it up.
3. Remove the coiled hair and debris from the shaft and bearings, conveniently using a plastic spatula (for example, from drug packaging) or tweezers.
4. Wash the bristles with warm water and soap if it is heavily contaminated.
5. Collect the brush in reverse order, making sure that the shaft rotates freely.

For the side brush:

• Then, pull it down (it is attached to the latch).
• Clean the hair and debris, and if the brush is deformed, replace it, it is inexpensive (about 300-500 rubles).
• Check the axis of rotation: if it is contaminated, wipe with a cotton swab soaked in alcohol.

💡

If the bristles on the brushes become hard and brittle, soften it by soaking it in warm water with air conditioning for underwear for 10 minutes. After that, rinse with clean water and dry.

5. Cleaning sensors and sensors: why the vacuum cleaner "blinds"

Xiaomi V9 sensors are responsible for navigation, obstacle detection and height control. If they are contaminated, the vacuum cleaner can:

• 🤖 Become less accurate in mapping.
• 🚧 Resist against walls or furniture.
• 🔋 Quickly discharge due to excessive maneuvers.

How to clean the sensors:

• 👁️ Laser sensor (LiDAR): under a transparent cap on top. Wipe the cap with a dry microfiber cloth. Do not use alcohol or wet wipes!
• 📏 Collision sensors: Perimeter bumper, clean them with a cotton swab dipped in water.
• 🔳 Height sensors: Down below. Blow them with compressed air or clean them gently with a brush.
• 🔋 Contacts of the charging station: wipe with an alcohol napkin if the vacuum cleaner does not dock well.

⚠️ Warning: If the vacuum cleaner still behaves strangely after cleaning the sensors (for example, it does not see the wall), check the settings. → Map. → Calibration of sensors in the Mi Home app.Sometimes a software failure leads to similar symptoms.

Deep cleaning: disassembly of the shell and fan

If after all the procedures, the vacuum cleaner still works worse than before, the problem may lie in the clog of the fan or ducts, which is a more complex procedure, but you can do it yourself.

Step-by-step:

1. Turn over the vacuum cleaner and unscrew the 4 screws on the bottom cover (use the PH0 cross screwdriver).
2. Carefully remove the cover, without pulling - sensor wires are attached to it.
3. Examine the fan, if it has accumulated dust, remove it with a brush or vacuum cleaner.
4. Check the ducts, the plastic ducts that connect the container and the fan, and clean them with a flexible brush.
5. Collect the vacuum cleaner in reverse order, making sure all the wires are connected.

If you're not sure about your abilities, you should contact the service. Incorrect assembly can lead to sensor errors or short circuit.

💡

Deep cleaning of the fan should be carried out no more than 1 time a year. Frequent disassembly of the case increases the risk of damage to seals and loss of warranty.

7. Battery care: how to extend the service life

Xiaomi V9 battery (usually Li-ion 5200 mAh) is designed for 300-500 charge cycles, but if used improperly, its capacity can fall within a year.

• 🔋 Don't keep the vacuum cleaner on charge all the time. 80-90% discharge 20-30%.
• 🔌 Use only the original charging station. Cheap analogues can damage the power controller.
• 🌡️ Keep the vacuum cleaner at temperature 10-25°C. Overheating or cold reduce battery life.
• 🔄 Calibrate the battery once every 3 months: completely discharge the vacuum cleaner (before turning it off), then charge up to 100% without interruptions.

If the vacuum cleaner is running out of 10-15 Check the battery status in the Mi Home app (Settings) → Battery status. If the tank has dropped below 60%, battery.
