Disassembly of hand vacuum cleaner Xiaomi: from screws to motor – a complete guide with photos

Xiaomi hand vacuum cleaners are among the most popular in Russia due to the combination of price, power and compactness. But even the most reliable equipment breaks down: traction drops, the body warms, or the battery stops holding charge. In 80% of cases, the problem is solved by cleaning or replacing consumables, but for this you need to properly disassemble the device without damaging plastic latches or seals.

This article is not a universal instruction "for all models", but a detailed analysis of processes taking into account the design features of the Mi Handheld Vacuum, Dreame lines. V9/V10/V12 Deebot H7/H8. We will show you what tools you will need, how to avoid common mistakes (such as breaking the filter mount) and what to do if the vacuum cleaner does not turn on after disassembly. For clarity, hidden “chips” of the design are given, which are not written in the official manuals – for example, how to remove the motor unit without the risk of breaking the wires.

1. Disassembly preparation: safety tools and measures

Before you take on the screwdriver, make sure that the problem really requires disassembly. For example, if the Xiaomi Mi Handheld vacuum cleaner is not good at sucking, first check:

• 🔋 Battery charge - at a level below 20% power-fall 30-40%.
• 🧹 Clean filters - clogged HEPA-filter reduces thrust by 60%.
• 🌀 Turbine nozzle - hair and threads are wound on the roller, blocking the rotation.

If cleaning doesn't work, prepare the tools. Xiaomi/Dreame enough:

• ⚒️ Cross screwdriver (PH0 or PH1 — model).
• 🔧 Plastic mediator (to separate latches).
• 📸 Smartphone – take pictures of each stage so as not to confuse wires during assembly.
• 🧲 Magnetic mat or screw box (in Dreame vacuum cleaners) V12 More than 15 pieces!).

⚠️ Warning: Do not use metal blades to separate the case - they leave scratches on the plastic.

Before disassembly it is necessary:

1. Disconnect the vacuum cleaner from the network (if it is connected to the docking station).
2. Remove the battery – in models with a removable battery (for example, Dreame) V10) This will prevent short circuiting.
3. Blow the body with compressed air - dust during disassembly can get into the bearings of the motor.

2. disassembly of the shell: where the screws and latches are hidden

The design of hand vacuum cleaners Xiaomi is built on a modular principle: the body consists of 2-3 And the problem is that there are invisible attachments that break when you open them in a careless way. 1C (similarly V9):

Step 1 Removing the top cover

• 🔍 Find 4 screws on the back (2 under rubber legs).
• 🔄 Carefully put the mediator seam between the upper and lower part of the body - latches are located along the perimeter.
• 📌 In the Dreame models V10+ There is a hidden screw under a sticker with a serial number!

Step 2. Disconnect the engine compartment

After removing the cover, you will see:

• 🔋 Battery (in a removable compartment or soldered to the board).
• 🌀 Turbine block (at models with a nozzle for carpets).
• 🔌 Wires going to the power button and motor.

⚠️ Attention: In Dreame vacuum cleaners V10 And the newer engine block is not only attached to the body by screws, but also by rubber shock absorbers. You can't pull them, you can just gently move them to the side!

Dismantling of the battery: removable vs. soldered

The battery is the most vulnerable element in a hand vacuum cleaner. Xiaomi models use lithium-ion batteries on a single-use basis. 2200–2500 Those who lose their capacity after 300-500 Charging cycles. Disassembly is necessary if:

• 🔋 The vacuum cleaner does not hold charge (lasts less than 10 minutes).
• ⚡ Not switched on or suddenly turned off.
• 🔥 Battery body swells (dangerously!).

Option 1. Removable battery (e.g. Mi Handheld) 1C):

1. Unscrew 2 screws on the bottom cover of the compartment.
2. Pull the tongue (orange tape) - the battery will come out of the connector.
3. Replace it with a similar (article: MDY-05-EM for 1C).

Option 2: soldered battery (e.g. Dreame) V12):

It's going to require a soldering iron and electronics experience.

1. Disconnect the wires from the control board (remember the polarity!).
2. Heat the contacts of the battery with a soldering iron (temperature not higher than 300)°C).
3. Put a plastic shoulder blade on the battery - it is glued to the body.

Dreame V12 It uses a 21700-format battery (6 cells), which can be replaced with a similar one from Samsung. 50E or LG MJ1. The main thing is to observe a sequential connection of cells!

4. Cleaning and replacing filters: HEPA, motor

Clogged filters - the reason №1 drop in suction power. Xiaomi vacuum cleaners use a multi-stage filtration system:

1. Inlet filter (grid in front of the engine) - traps large debris.
2. Motor filter (sponge) - protects the engine from dust.
3. HEPA-filter - traps particles up to 0.3 μm in size.

How to clean:

• 🧽 Inlet filter – wash under warm water, dry for 24 hours.
• 🧼 Motor filter - vacuum or replace (article: WJQFB01ZM Mi Handheld).
• 🚫 HEPA-Don't wash the filter, just replace it once in a while. 3-6 months.

In the Dreame models V10 And the newer one is a cyclone filter with a metal mesh:

1. Take the trash can off.
2. Unscrew 3 screws on the cover of the cyclone.
3. Wash the net and plastic separator (do not use aggressive detergents!).

⚠️ Warning: After cleaning the filters, be sure to check the tightness of the sealing rubber bands. If they are torn, dust will seep into the engine, which will lead to overheating.

💡

If after cleaning the filters the vacuum cleaner began to work louder, check whether it is installed correctly. HEPA-Filtering up increases the load on the motor, causing vibration and noise.

5. disassembly of the motor unit: when you need to replace brushes

The motor is the “heart” of the vacuum cleaner, and its disassembly is required in two cases:

1. 🔊 Increased noise or vibration (wear of bearings).
2. 🔥 Overheating of the body (clogged cooling channels or worn brushes).

How to get to the motor:

1. Remove the upper cover of the case (see section 2).
2. Disconnect the wires from the control board (take a picture of the circuit!).
3. Unscrew 4 screws, fastening the motor unit to the body.
4. Carefully remove the unit - it is connected to the turbine with a flexible hose.

In the engines of vacuum cleaners Xiaomi most often fail:

• 🔌 Coal brushes - washed after 200-300 work-hours.
• 🌀 Bearings - wear out due to dust.
• 🧲 Rotor winding - burns out when overheating.

You can replace the brushes yourself:

1. Remove the rear cover of the motor (2 screws).
2. Remove old brushes (they are held on springs).
3. Install new ones (for example, 3x5x8 mm for Mi Handheld 1S).

If the engine does not start at all, check:

• 🔌 Integrity of the winding (multimeter in resistance mode).
• 🔄 Management fee work (often burns out the simistor).

💡

If the engine sparkles when you're working, it's a sign of wear and tear or pollution in the collector, and cleaning with alcohol and replacing the brushes solves the problem 90 percent of the time.

6.Typical Disassembly Mistakes and How to Avoid Them

Even experienced vacuum cleaners make mistakes that lead to a vacuum cleaner breakdown.

Another common problem is lost screws or springs. V12, For example, there's a tiny spring under the power button, without which the mechanism doesn't work.

What to do if the vacuum cleaner does not turn on after disassembly?

1. Check if the connectors are properly connected to the control board.
2. Make sure the battery is charged (voltage not lower) 21V).
3. Call the switch on multimeter – it should “ring” when pressed.

7.Where to buy Xiaomi vacuum cleaner parts

Original spare parts for Xiaomi vacuum cleaners can be ordered:

• 🛒 Official Xiaomi store (minus – long delivery).
• 🌍 AliExpress – search by article (e.g., by article, WJQFB01ZM for the Mi Handheld filter).
• 🏬 Local service centers – often sell used parts from repairs.
• 🔧 Radio parts stores - for brushes, bearings, wires.

Average Parts Prices (2026):

• 🔋 Battery: 1500–3000 ₽ (model-wise).
• 🌀 HEPA-filter: 300-800 ₽.
• 🔌 Motor brushes: 200-500 ₽ (kit).
• 🧲 Management fee: 1000–2500 ₽.

When buying, pay attention to:

• 📌 The article must be the same as the original.
• 📅 Release Date – Old Parts May Be Weared.
• 📦 Package – often sell “whales” for repairs (e.g. brushes) + bearing).

⚠️ Warning: Be careful of "universal" parts from unknown brands, such as non-original parts. HEPA-filters can pass up to 30% of dust, which negates all filtering.
