How to clean the fan Xiaomi Tower: disassembly, cleaning and assembly

Xiaomi Tower fans (Mi Smart Standing Fan, Mi Tower Fan Pro and others) have become popular thanks to a combination of power, quiet operation and smart features. However, over time, even the most reliable appliances require maintenance: dust, animal hair and household pollution accumulate on the blades, filters and inside the case, worsening performance and increasing noise. Regular cleaning not only prolongs the life of the device, but also prevents the engine from overheating, which can lead to breakage.

In this article, you will find step-by-step instructions for disassembling, cleaning and assembling a fan, tailored to Xiaomi’s design, what tools you’ll need, how to safely reach internal nodes, and how to care for different models, with a special focus on cleaning a brushless engine, a key element that is often ignored in self-service.

Preparation for cleaning: tools and safety measures

Before you start disassembling, make sure you have everything you need, and the wrong tools or haste can damage plastic latches or electrical contacts.

You'll need:

• 🔧 Cross screwdriver (usually the size is suitable) PH2) — hull-rotor.
• 🧴 Soft brush (dental or dust brush) - for cleaning the blades and grilles.
• 🧽 Microfiber fabric - for cleaning plastic parts.
• 💨 Vacuum cleaner with a narrow nozzle - to remove dust from hard-to-reach places.
• 🔌 Tape or marker - to mark the wires during disassembly (if necessary).
• 🧤 Gloves (optional) – to protect hands from dust and sharp edges.

Important: Before starting work, disconnect the fan from the network and wait for the blades to stop completely (some models have inertial rotation). If the fan is connected to the Mi Home app, disconnect it from Wi-Fi to avoid accidental switching on during cleaning.

⚠️ Warning: Do not use metal objects (knives, screwdrivers) to scrape dirt off the blades - this can disrupt balancing and cause vibration when working).

Disassembly of the fan Xiaomi Tower: a step-by-step guide

Xiaomi Tower fans are designed to be partially disassembled without being completely dismantled, but deep cleaning (such as engine or bearings) requires removing the back cover.

Partial disassembly (cleaning of blades and filter)

This method is suitable for regular care and does not require special skills:

1. Remove the protective grille from the front of the fan. It's usually attached to the latches -- gently pull it on yourself, starting at the top or bottom edge.
2. Remove the rough filter (if your model has one), which is fixed with magnets or slots in some versions.
3. Remove the front panel to access the blades. In Mi Tower Fan Pro models, it is mounted on two screws at the bottom (under rubber plugs).

Complete disassembly (cleaning of engine and internal components)

If the fan is noisy or spinning poorly, you'll need to disassemble it completely, which is a more complex process and requires caution.

1. Unscrew all the screws on the back cover (usually 4-6 pieces). In some models, the screws are hidden under stickers or rubber legs.
2. Carefully remove the lid, don't pull the wires! unplug the power and control connectors (take a picture of their location before that).
3. Remove the bladed engine. In brushless models, it can be attached to shock absorbers -- don't hurt them.

Cleaning of blades and filters: remove dust and dirt

Xiaomi Tower fan blades are asymmetrical in shape for optimal airflow, so cleaning them requires a special approach. Improper handling can disrupt aerodynamics and increase noise.

Blade cleaning

Use a soft brush or vacuum cleaner to remove dust from both sides of the blades.

• 🧼 Moisten the microfiber fabric in soapy solution (do not use aggressive detergents!).
• 🪟 Wash the blades in the direction of their shape (not across) so as not to damage the coating.
• 💧 Make sure there is no moisture left on the blades before assembly.

Cleaning filters

Filters in Xiaomi fans come in two types:

For carbon-filled filters (active carbon), vacuum cleaners are ineffective, and should be replaced every 6-12 months depending on the intensity of use. In Xiaomi models, filters can be ordered by article:

• FBF-MFIL01 — For the Mi Tower Fan 1S;
• FBF-MFIL02 — Mi Tower Fan Pro.

💡

If the fan is still making noise after cleaning the blades, check the balance: gently scroll the blades manually - they should stop in an arbitrary position. If one side is heavier, it may have dirt or damaged plastic.

Cleaning the engine and bearings: how to eliminate noise

If the Xiaomi Tower fan started buzzing, creaking or vibrating, the problem most often lies in the engine or bearings (BLDC), The wear and tear that is used in most Xiaomi models is slow, but dust can penetrate and worsen cooling.

Engine cleaning

To access the engine:

1. Remove the back cover (as described in the section on disassembly).
2. Remove dust from the engine radiator with a brush or vacuum. Do not use wet fabric!
3. Check the contacts and wires for oxidation, and clean them with a smooth sweep if necessary.

Bearing lubrication

In models with sleeve bearings (for example, Mi Tower Fan) 1S) You may need lubrication over time. Use silicone lubricant (not litol or solidol!):

1. Apply 1-2 drops of lubrication to the engine shaft (not on the windings!).
2. Scroll the blades manually several times to ensure the lubrication is distributed.
3. Remove the excess with a napkin.

⚠️ Note: In brushless models (Mi Tower Fan Pro, Mi Smart Standing Fan 2), bearings are usually closed and do not require lubrication.

Fan assembly after cleaning: avoiding mistakes

Incorrect assembly can lead to vibration, noise or even short circuit.

1. Make sure all wires are connected correctly (check the photos taken before disassembly).
2. Check that the blades rotate freely - without touching the body.
3. Twisting the screws cross-cross to avoid skewing the cover.
4. After assembly, turn on the fan at minimum speed and check for no extraneous noise.

In models with a remote control (Mi Tower Fan Pro) after assembly may require resetting.

1. Hold the Power button on the body for 5 seconds.
2. Connect the fan to the Mi Home app again.

💡

After assembly, be sure to check the fan at all speeds, if there is vibration, then the blades are installed asymmetrically or damaged during cleaning.

Frequency of cleaning and pollution prevention

The recommended frequency of service depends on the operating conditions:

• 🏡 Home Use (Clean Room): Every 3-6 Months.
• 🐕 Animals: once every 1-2 months (wool quickly clogs filters).
• 🌿 High humidity or dustiness: once every 1-3 months.
• 🏭 Industrial premises: monthly or more often.

To reduce pollution:

• 🌬️ Install the fan away from dust sources (carpets, open windows).
• 🔄 Ventilate the room regularly to reduce the accumulation of dust in the air.
• 🧹 Use an air purifier (e.g. Xiaomi Mi Air Purifier) paired with a fan.

In the Mi Tower Fan Pro, clean the ionization plates once a month, and they attract dust with an electrostatic charge.

1. Turn off the ionizer in the settings.
2. Remove the plates (usually located behind).
3. Wash them under water and dry them.

Frequent problems after cleaning and their solution

Even with a careful cleaning, you can have problems.

If after cleaning the fan does not gain momentum or turns off on its own, this may indicate:

• Problems with the tachogenerator (speed sensor).
• Overheating of the engine due to a faulty radiator.
• Damage to the control board (for example, after moisture is ingested).

In such cases, it is recommended to contact the Xiaomi service center, especially if the device is warranty.

💡

If the fan has started to emit high-frequency squeak, it may be due to the resonance of the blades, try to slightly change their angle (if the design allows) or move the fan to another place.
