Xiaomi hair dryer is not just a household appliance, but a high-tech device with a powerful motor and filtration system. Over time, dust, hair and small debris accumulate inside, causing the engine to overheat, reduce power and even break down. Regular cleaning extends the life of the hair dryer by 30-50%, but many users are afraid to disassemble the equipment themselves.
In this article, you will find detailed cleaning instructions for popular Xiaomi Mi Air, Supersonic and others, including hidden latches and design features that are not mentioned in the official manuals, we will understand what tools you need, how to avoid damage and when to contact the service center.
Why Xiaomi hair dryer should be cleaned regularly
Unlike cheap ones, Xiaomi hair dryers are equipped with a two-stage filtration system: rough (net at the air inlet) and thin (internal filter in front of the engine).
- 🔥 Engine overheating – the temperature inside the body may exceed 100°C, which reduces the life of the motor.
- 💨 Power reduction – clogged filters reduce airflow by 20-40%, hair drying takes longer.
- 🔊 Noise amplification – the motor is running at its limit, causing vibrations and hum.
- ⚡ Increased power consumption – a dirty dryer consumes 15-25% more electricity.
The manufacturer recommends brushing the hair dryer every 3-6 months with heavy use (daily) or once a year with rare. However, if you dry long hair or use styling products (varnishes, mousses), the interval should be reduced to 2-3 months.
⚠️ Warning: If the dryer starts to spontaneously shut down after 1-2 minutes of operation, this is a sign of critical overheating. Stop using immediately and clean the device!
What Xiaomi models can be cleaned independently
Not all Xiaomi hair dryers are equally easy to disassemble, here is a list of models for which self-cleaning is suitable:
| Model | Type of disassembly | Features | Difficulty (1-5) |
|---|---|---|---|
| Xiaomi Mi Air | Partial (removable back cover) | Filter on latches, the engine does not require lubrication | 2 |
| Xiaomi Supersonic | Complete (removal of the hull) | Two filters, require a T5 screwdriver | 4 |
| Xiaomi Viomi V1 | Partial (folding panel) | Magnetic filter, easy to clean | 1 |
| Xiaomi Dreo DHT51 | Full (screws under legs) | Thin stainless steel filter | 3 |
Xiaomi Soocare models and some versions of the Mi Air Pro have a non-shattered body - it is better to trust their cleaning to the service center. Trying to open such a hair dryer yourself will lead to loss of warranty and risk of damage to the PCB.
Preparation for cleaning: tools and safety measures
Before disassembling the hair dryer, prepare:
- 🔧 Screwdrivers: cross (PH0 or PH1) and torx (T5 or T6) - depending on the model.
- 🧲 Magnet or tweezers for the extraction of small screws.
- 🧹 Soft brush (e.g., makeup) or toothbrush.
- 💨 Compressed air balloon (optional, for blowing dust out of hard-to-reach places).
- 🧼 Alcohol wipes or cotton swabs for cleaning contacts.
Make sure you're safe.
- ⚡ Turn off the dryer and wait for a full cooling (at least 30 minutes).
- 🧤 Wear rubber gloves - sharp edges of plastic may remain inside the case.
- 👓 Use safety glasses if you blow out dust with compressed air.
⚠️ Warning: Never use water or liquid detergents to clean interior parts! moisture can cause contacts to corrosion or short circuit the next time you turn on.

Step-by-step: how to disassemble and clean the Xiaomi hair dryer
Consider the process with the Xiaomi Mi Air, the most popular model, and the steps may differ slightly for other hair dryers (see table above).
Step 1: Removing the back cover
Turn the hair dryer over and find two screws under the rubber legs (you can put them in a flat screwdriver). Unscrew the screws and gently pull the lid on yourself, which is held on plastic latches.
Don't make an effort! If the lid doesn't lend itself, check if all the screws are twisted. On the Supersonic model, you also need to remove the decorative grille at the air inlet (it is attached to the clips).
Step 2: Extract the filter
Under the lid, you'll see a removable filter (a mesh or porous material) and pull it out carefully by pulling it over the edge. In Viomi models, the filter is magnetic, just screw it.
If the filter is heavily contaminated (covered with a sticky coating from hairspray), soak it in a warm soap solution for 10-15 minutes, then rinse under running water and dry for at least 24 hours.
Step 3: Cleaning the motor and blades
With a brush or compressed air, remove dust from the fan blades and motor body. Don't touch the engine brush! - this can damage the winding. For hard-to-reach places, use a cotton swab dipped in alcohol.
Supersonic models have a second filter in front of the engine, which needs to be cleaned separately, and if the engine shows traces of oily spots, it is a sign of wear and tear of the bearings (maintenance is required).
Step 4: Assembling a hair dryer
Place the filter in place, making sure it fits tightly. Close the lid and twist the screws. Don't pull over! - this can lead to cracks in the plastic.
Before the first inclusion after cleaning, allow the hair dryer to stand for 10-15 minutes - this is necessary to weather the remains of alcohol (if used).
What if after cleaning the hair dryer began to work louder?
Cleaning without disassembly: alternative methods
If you are not confident in your abilities or the hair dryer has an indissoluble body, you can use gentle cleaning methods:
- 💨 Compressed air purge: direct the jet of air into the air intake holes (hold the balloon vertically to avoid liquid ingress!). Efficiency: ~60% of complete cleaning.
- 🧲 Magnetic cleaning: Hold a powerful magnet to the hair dryer grille to help extract metal particles (e.g. from the clips) suitable for metal filter models.
- 🌀 Vibration method: turn on the hair dryer at maximum power and gently tap the body with a wooden stick. Dust will fly out through the outlet (do it outside!).
These methods are less effective, but they are safe for inexperienced users, and can be alternated with a complete cleaning every 1-2 years.
💡
If your Xiaomi hair dryer has an ionization function, after cleaning, check it: put the hair dryer to a thin stream of water from the tap. If the jet deviates, the ionizer works properly.
Frequent Mistakes and How to Avoid Them
Even with careful cleaning, users often make mistakes that lead to breakdowns.
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Using water to clean the motor | Short circuit, corrosion of contacts | Use only dry methods or alcohol |
| Loss of screws or springs during disassembly | Unstable work, rattling | Putting parts in a container or photographing the process |
| Cleaning the dryer on the grid | Electric shock. | Always turn off the food and wait for it to cool down. |
| Use of aggressive detergents | Eating plastic, damaging the filter | Use only soapy solution or alcohol |
Another common problem is that the plastic latches get damaged when you build them. If the lid doesn't lock, check:
- 🔍 Did all the latches fall into the grooves (sometimes they bend).
- 🔧 Are the screws tightened (this deforms the body).
- 🧩 Are there any foreign objects between the lid and the body?
When cleaning doesn’t help: Signs of serious malfunctions
If, after cleaning the hair dryer,
- 🔥 Overheats and shuts down after 30 seconds of operation;
- 💨 Does not blow or blow very weakly;
- 🔊 Sneaks or vibrates;
- ⚡ Sparks when switched on,
The problem is deeper than clogged filters.
- 🛠️ Wear of motor bearings (requires replacement or lubrication).
- 🔌 Electrical problems (wire break, button malfunction).
- 🌀 Damage to fan blades (cracks or deformation).
- 🔥 Failure of the thermal fuse (a common cause of spontaneous shutdown).
In these cases, it is not recommended to try to repair the hair dryer yourself - it is better to contact an authorized Xiaomi service center. The average cost of diagnosis: 500-1000 rubles, engine repair: 1500-3000 rubles.
💡
If the Xiaomi hair dryer is warranty (usually 12 months), do not disassemble it yourself! filter cleaning can be done without opening the case (see section "Alternative methods"), but any intervention will void the warranty.
