Disassembly of the vertical vacuum cleaner Xiaomi: instructions with nuances for models 2020-2026

Xiaomi vertical vacuum cleaners are a popular cleaning solution due to their compactness and power. However, over time, even the most reliable equipment requires maintenance: cleaning filters, replacing brushes or eliminating a blockage in the hose. You can disassemble the vacuum cleaner yourself without going to the service center, but it is important to do this carefully so as not to damage plastic latches or electronic components.

In this article, you will find a step-by-step instruction with photo and video examples, a tool compatibility table for different models (Mi Handheld Vacuum Cleaner, MiJia 1C, Dreame V11, etc.), as well as a list of typical errors that lead to breakdowns.

⚠️ Warning: Disassembly of Xiaomi vacuum cleaner can void warranty if there are traces of autopsy on the case. Check warranty service period in documents or in the Mi Home app before work begins.

1. Disassembly preparation: safety tools and measures

Before disassembling the vacuum cleaner, make sure it is completely discharged. Lithium-ion batteries (for example, in the Xiaomi Mi Handheld Vacuum Cleaner 1C models) can ignite if damaged, so you need to work with them carefully.

• ✅ Plastic blades (to separate latches without scratches).
• ✅ Cross screwdriver (usually suitable) PH0 or PH1).
• ✅ Tweezers (to extract small parts, such as spring contacts).
• ✅ Soft fabric (so as not to scratch the body during disassembly).
• ✅ Hair dryer (for heating adhesive joints, if the body is not disassembled).

If you're taking a vacuum cleaner apart for the first time, take a video of the process or take a photo of each step, which will help you put the device back together without any unnecessary details. In Dreame V11/V12 models, the charge sensor calibration can be lost after disassembly, and you'll have to reset it through the app.

⚠️ Warning: Do not use metal screwdrivers to separate plastic latches, this leads to cracks. 80% of breakages after self-disassembly are due to damaged mounts.

Removal of the upper cover and access to the battery

Most of Xiaomi’s vertical vacuum cleaners are similar in design: the top cover is mounted on 4-6 latches and 2-3 screws. Let’s start with the Mi Handheld Vacuum Cleaner 1C model (also relevant for the Dreame V10):

1. Turn over the vacuum cleaner and remove the dust container (click on the Release button on the handle).
2. Unscrew the screws on the bottom of the body (usually they are hidden under rubber legs - gently tuck them with a spatula).
3. Insert a plastic blade into the gap between the top and bottom of the case at the power button. Carefully guide it around the perimeter, disconnecting the latches.
4. Once the lid is removed, you'll see the battery (usually 21.6V 2500mAh), the control board and the motor. Don't pull the wires - they can break away from the board!

In the Dreame V11 and later, the battery is additionally fixed with adhesive tape to remove it:

1. Warm up the place of fastening of the battery with a dryer (temperature not higher than 60 ° C).
2. Tap the battery with a plastic spatula and slowly pull up.
3. Disconnect the power plume from the board (it is held on the clamp - gently flick it with tweezers).

⚠️ Warning: If the vacuum cleaner does not turn on after the battery is removed, check the fuse on the board (small black cylinder next to the contacts.

Cleaning filters and turbines: what can be done without a complete dismantling

You don't always have to disassemble a vacuum cleaner completely. 90% of power loss problems are solved by cleaning or replacing filters. Xiaomi's vertical vacuum cleaners usually have three:

For filter cleaning:

1. Remove the dust collector and wash. HEPA-filter under running water (dry for at least 24 hours!).
2. The pre-filter (sponge) can be vacuumed or washed with soap.
3. The motor filter is cleaned with a dry brush or compressed air (do not wash!).

If the vacuum cleaner is buzzing but not sucking in, the problem may be a turbine clog.

• 🔧 Remove the brush-nozzle and check the hose for debris (bleed it with a dryer in cold air mode).
• 🔧 Unscrew turbine mount screws (usually 3 screws under the lid).
• 🔧 Remove the wound hair or threads from the turbine shaft with tweezers.

💡

If the vacuum cleaner still sucks poorly after cleaning the filters, check the tightness of the hose. Often the problem is microcracks that are not visible to the naked eye. Load the hose in the water and see where the air bubbles appear.

Disassembly of the brush-nozzle and elimination of blockages

The brush nozzle (especially in electric-powered models such as the Dreame V11) is often clogged with hair and threads.

1. Press the Release button on the body of the brush and remove the roller drum.
2. Put the plastic cover on the end of the brush (there are 2 latches hidden).
3. Remove the shaft with brushes and clean it of the wound debris. Use a toothpick or needle for convenience.
4. Check the bearings of the shaft - if they are backlash, the brush will have to be replaced.

In brushes with lighting (for example, Mi Electric Mop) 2-in-1) Check your contacts further LED-If the backlight doesn't work, there may be a reason:

• 💡 Oxidation of contacts (clean with alcohol).
• 💡 Breaking wire (needs soldering iron for repair).
• 💡 Driver failure LED (fee-change).

5. Diagnosis of malfunctions: when disassembly will not help

Not all breakdowns can be repaired on their own, but here are the signs that you should contact the service:

• ⚡ The vacuum cleaner does not turn on, although the battery is charged (the control board may have burned out).
• ⚡ When working, a grinding or knocking is heard (breakdown of turbine bearings).
• ⚡ Battery discharges in 5-10 minutes (requires a replacement battery).
• ⚡ The vacuum cleaner spontaneously shuts down (faulty thermal sensor).

For the diagnosis of the control board:

1. Call the multimeter circuit from the battery to the motor (resistance should be close to 0 Ohms).
2. Check the fuse (it is located next to the power connector).
3. Check the board for the presence of burned elements (blackened resistors, bloated capacitors).

If the Xiaomi vacuum cleaner does not hold the charge, but the battery is normal, the problem may be in the charge controller, in which case you need to flash the board through the USB-C port (you need special software, for example, MiFlash).

💡

The most common cause of breakdowns after dismantling is damage to plumes. Always unplug them gently by pulling the plastic connector, not the wires!

6. Assembly of the vacuum cleaner: how to prevent errors

To collect the vacuum cleaner you need in reverse order, but there are several nuances:

1. Make sure all rubber seals (e.g., on a dust collector) are in their places, and their loss will result in a loss of suction power.
2. Check that the plumes are not twisted and clamped with the body.
3. Twisting the screws cross-cross to avoid skewing the cover.
4. After assembly, turn on the vacuum cleaner and check the work at minimum power - if everything is in order, test at maximum.

If the vacuum cleaner does not turn on after assembly, check:

• 🔌 Correct battery connection (contacts should fit tightly).
• 🔌 Reliability of the control board fastening (screws should not hang around).
• 🔌 Integrity of the fuse (if necessary, replace it with a similar one with the same nominal value).

⚠️ Warning: If the vacuum cleaner is humming after assembly but not suctioning, chances are you forgot to install one of the filters or improperly assembled the dust collector. Disassemble it again and check the leakage.

7. Post-disassembly service: how to extend the life of a vacuum cleaner

To make Xiaomi vacuum cleaner last longer:

• 🧹 Clean the filters every 1-3 months (depending on the intensity of use).
• 🧹 Store the vacuum cleaner in a dry place – moisture leads to corrosion of contacts.
• 🧹 Do not use a vacuum cleaner to clean construction dust without a special filter (this will clog the engine).
• 🧹 Charge the battery up to 80% if you don’t plan to use the vacuum cleaner for a long time (this will prolong battery life).

For smart-controlled models (like the Dreame V12), update your firmware regularly through the Mi Home app. Newer versions often fix bugs that overheat or misoperate sensors.

💡

If the vacuum cleaner is getting worse but the filters are clean, try resetting to factory settings. Hold the power button for 10 seconds (up to double signal).
