Disassembling the vacuum cleaner Xiaomi V11: a complete guide with photos and repair tips

The Xiaomi Mi Robot Vacuum-Mop V11 is one of the most popular cleaning robots on the market because of its performance and convenience. However, even the most reliable appliances require maintenance: over time, dust accumulates inside, filters clog, and brushes wear out. Disassembly of the device may be necessary for deep cleaning, replacement parts or fault diagnosis. But before you start screwdriver, it is important to understand that the design of the V11 has its own characteristics, and improper actions can lead to sensors breakage or damage the body.

In this article, you will find step-by-step instructions with photos of key stages, a list of necessary tools and hidden nuances that are not written about in the official manuals. We will also tell you which parts you can clean yourself and which you should contact the service center. If your Xiaomi V11 has become worse at collecting garbage, making extraneous sounds or not holding a charge, perhaps the reason lies inside.

⚠️ Warning: Disassembling Xiaomi vacuum cleaner V11 You can cancel the warranty if it's still valid. Before you start, check the warranty period in your documents or through the Mi Home app. If the device is warranty, contact your authorized service center.

Preparation for disassembly: tools and security measures

Before you start disassembling, prepare the workplace and the necessary tools. The Xiaomi V11 cleaner robot contains fragile plastic latches and other sensors, so you need to act carefully.

• ✅ Plastic mediators or shoulder blades - to disconnect the body without scratches (metal screwdrivers can damage plastic).

We also recommend downloading the official user manual for your model (V11 Omni or V11 Storm) in advance, as some elements may differ in location. In models from 2023 and later, unauthorized screws (Torx Security T5) are used, which will require a special screwdriver.

⚠️ Warning: Before disassembling, drain the battery (up to 0%) and leave the vacuum cleaner for 10-15 minutes.This minimizes the risk of short circuits when contacts accidentally close. Do not disassemble the device immediately after cleaning - let it cool, especially if you cleaned the carpets.

Removal of the upper cover: the secrets of latches and hidden screws

The most difficult step is to carefully separate the top panel from the base. Xiaomi V11 uses a system of hidden latches and 4-6 screws (depending on the modification).

1. Turn over the vacuum cleaner and remove the garbage container (click on the unlock button at the back).
2. Remove the side brush (turn counterclockwise) and the main brush (click on the locks on the sides).
3. Unscrew the screws under rubber plugs (usually 2 pieces in front and 2 in the back).
4. Carefully unplug the lidar protective cover (a transparent plastic cap) by pulling it upwards. There's another screw hidden underneath!

Now, to the latches, they're perimeter-sized, and they often break when you open the vacuum cleaner in a sloppy way, start at the back of the vacuum cleaner (on the side of the switch), and then move forward gradually using the mediators, and only exert force after you hear the characteristic click of the first latch.

⚠️ Attention: In models V11 Omni under the top cover passes a plume connecting the power button to the motherboard. Don't pull the lid up sharply - first lift it 1-2 cm and gently disconnect the plume by pulling the black tongue of the retainer.

Dismantling of battery and control board

Once the top cover is removed, you'll see a battery pack (usually 5200 mAh in a V11), motherboard and motor unit, and the battery is mounted on 2-3 screws and plugged in through a reverse polarity jack to extract it:

1. Unscrew the propellers holding the battery (usually marked with red circles on the board).
2. Carefully lift the battery and disconnect the power connector.
3. If the battery is swelling, don't try to puncture or bend it, it can cause fire, in which case, dispose of the battery immediately according to local regulations.

The motherboard in the Xiaomi V11 is located under a metal screen to dismantle it:

• ⚙️ Unscrew 4 screws at the corners of the screen.
• ⚙️ Disconnect all plumes (usually 3-4: power, motors, sensors and Wi-Fi antenna).
• ⚙️ Take a picture of the location of the plumes before disconnecting - this will help with the reverse assembly.

💡

If the vacuum cleaner doesn't turn on after disassembly, check the density of the battery contacts. Often the problem is oxidation of the connector - clean it with alcohol and cotton swab.

Cleaning and Replacement of Key Components

Now that the body is disassembled, we can start servicing the interior parts.

• 🌀 Main brush and side brushes - clean the wound hair and thread. V11 a brush with an anti-tangled mechanism is used, but it still requires regular cleaning.
• 🔄 Filters HEPA — There are two of them: the prefilter (gray grid) and the main HEPA-filter (white) Only pre-filter can be washed! HEPA-The filter is replaced every 3-6 months.
• 🌀 The turbine fan is the main source of noise. The dust between the blades reduces the suction force. Clean with a soft brush.
• 📡 Lidar and optical sensors -- wipe with a microfiber wipe. Don't use lidar alcohol! Dry cleaning is enough.

If your Xiaomi V11 doesn’t pick up garbage on carpets, check the sealing gums in the dumpster. Over time, they lose elasticity, and the system’s tightness is broken. Replace them with new ones (V11 article – MDY-08-01).

⚠️ Note: When replacing brushes or filters, use only original parts or certified counterparts. Cheap Chinese copies can damage the motor or suction system. For example, non-original side brushes often have stiffer bristles, which leads to increased wear of the gearbox.

Diagnosis of malfunctions: when disassembly does not help

Sometimes even after a full cleaning, the vacuum cleaner doesn't work properly, and here are the typical symptoms and their possible causes:

If the vacuum cleaner produces an E1 or E2 error, it is usually due to sensor problems. The Xiaomi V11 has a hidden test mode that helps diagnose malfunctions without disassembling:

1. Hold the Home and Spot Cleaning buttons for 5 seconds until you hear the beep.
2. The vacuum cleaner will voice the error code (e.g., 3 short signals = lidar problem).
3. Check the code against the official error table.

⚠️ Warning: If after disassembly the vacuum cleaner has stopped responding to commands from the Mi Home app, check the Wi-Fi module connection (a small board with an antenna next to the motherboard). Often the plume leaves when the assembly is sloppy.

💡

Most of the errors in the Xiaomi V11 work are due to sensor contamination or poor contact of plumes. Before you carry the device for repair, try to completely disassemble, clean and reassemble, which solves 70% of the problems.

Cleaning the vacuum cleaner: how to avoid mistakes

Assembly is no less responsible than disassembly.

• 🔧 Make sure all the plumes are connected to the end (the snap of the lock should be heard).
• 🔧 Screw the screws cross-cross to avoid skewing the body.
• 🔧 Before final assembly, check the operation of all buttons and sensors.
• 🔧 Do not make excessive efforts when closing latches - if the lid does not sit down, then something is in the way (check the location of the plumes).

After assembly, perform a test run:

1. Check the rotation of the main and side brushes (there should be no extraneous sounds).
2. Make sure the lidar rotates freely (no creaking should be made).
3. Run cleaning through the app and check the suction force.

If the vacuum cleaner makes a whistling sound after assembly, it's a sign of air sucking, so go back to checking the leakproofness of the dumpster and the sealing gums.

When to contact the service center

Not all breakdowns can be repaired by yourself.

• ⚡ Battery swollen or does not hold charge (even after replacement).
• ⚡ The vacuum cleaner is not turned on and the indicators do not burn (maternity board problem is possible).
• ⚡ Lidar rotates in jerks or does not rotate at all (requires a replacement of the lidar motor).
• ⚡ After a fall or impact, the vacuum cleaner moves in a circle (possible damage to the gyroscope).

The cost of repairs in authorized Xiaomi service centers varies:

• Battery replacement: ~3 500–5 000 ₽.
• Lidar replacement: ~6 000–8 000 ₽.
• Maternity board repair: ~4 000–10 000 ₽ (depending on the breakdown).

⚠️ Attention: If your Xiaomi V11 You're still guaranteed, but you've already opened the case, the service center may refuse to repair it for free, so you'd better not mention the self-disassembly or go to an informal workshop.
