How to disassemble the vacuum cleaner Xiaomi V10: detailed instructions with photos and tips

The Xiaomi Mi Robot Vacuum-Mop V10 (also known as the Viomi V10 or Xiaomi V10 STYJ02YM>) is a popular model among smart robot vacuum cleaners, combining powerful suction, wet cleaning and advanced navigation. However, even the most reliable equipment requires maintenance: dust accumulates over time, filters clog, and mobile mechanisms wear out.

Deep cleaning of dust and dirt in hard-to-reach places;

- replacement of consumables (brushes, filters, wipes for wet cleaning);

repair (failure of the engine, sensors, battery);

- modernization (installation of additional filters or seals).

In this article, you will find a step-by-step guide with photos of key steps, a list of necessary tools and unique tips that are not found in the standard instructions, we will also reveal hidden latches and mounts that are not reported even by service centers, and warn about typical errors leading to breakdowns.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need, the wrong tool can damage plastic parts or leave scratches on the case.

• ✅ Plastic mediators (2-3 (a) to separate latches without damage.
• ✅ Cross screwdriver (PH0 or PH1) — hull-rotor.
• ✅ Tweezers – to extract small parts (for example, spring contacts).
• ✅ Multimeter – to check the voltage of the battery (optional).
• ✅ Silicone gasket or suction cup - will help remove the glass lidar cover.
• ✅ Isopropyl alcohol (70%+) — Cleaning contacts and sensors.

⚠️ Warning: If your vacuum cleaner is warranty-free, disassembly will cancel it. The manufacturer recommends that you contact the service center for any interventions. Also, don't disassemble the device immediately after cleaning - let it cool down. 1-2 hours to avoid deformation of plastic from heat.

Removal of the upper cover and access to the insides

So, the hardest part to start with is the top panel dismantling, and the key is to take your time and follow a strict sequence, or you're going to break the latches.

1. Turn the vacuum cleaner upside down (on the back cover). Make sure the power button is closer to you.
2. With a plastic mediator, gently pull the front panel (on the IR side) at the junction with the main body. You will hear the characteristic click - this is the first latch.
3. Move the mediator along the edge, gradually releasing the remaining latches, 6 in total: 2 on the sides, 2 on the front and 2 on the back.
4. After removing the front panel, you will see 4 screws under the cross screwdriver - unscrew them.
5. Now you can take the top cover off. It's mounted on two hidden latches underneath the battery -- pull the lid up with a little effort.

💡 Tip: If the lid fails, check if there are any unscrewed screws left. Often users miss the screw under the reset button (it is hidden under a rubber plug).

Dismantling of battery and power system

The Xiaomi V10 battery is one of the most vulnerable parts of the device, and over time, it loses capacity and the contacts oxidize.

1. Disconnect the power connector from the motherboard (it is white, with 4 contacts).
2. Unscrew 2 screws that lock the battery unit.
3. Carefully lift the battery. It can be glued to the body - use a plastic mediator to tamper with it.

⚠️ Warning: Do not touch the battery contact group with your bare hands - static electricity can damage the controller. If you plan to replace, choose a battery with parameters 14.8V 5200mAh (original: STYJ02YM-01).

Once the battery is removed, inspect it for swelling or corrosion. If the contacts have greenish coating, clean them with alcohol. Don't use abrasive materials - they will damage the protective coating.

💡

If the vacuum cleaner is running out quickly, check not only the battery but also the conductive rails at the charging station, and their oxidation is a common cause of poor contact.

Disassembly of the engine and suction system

The Xiaomi V10 engine is the heart of the device, and it needs to be cleaned every 6-12 months (depending on the intensity of use).

1. Remove the dust collector and HEPA filter (they are attached to the latches).
2. Unscrew 3 screws on the bottom cover (under the dust collector).
3. Carefully remove the cover - there is a turbine engine under it.
4. Disconnect the engine power connector (black, 2 contacts) and the duct (flexible hose).
5. Unscrew the 4 screws holding the engine and remove it.

🔧 Technical nuance: In the engine V10 brushless (BLDC), Bearings can get clogged with dust, use compressed air (a canister) or a soft brush to clean them, and do not oil the bearings, which will cause dust to stick and jam.

If the engine makes extraneous noise, check:

• 🔄 Turbine blades for cracks or deformation.
• 🕳️ The air duct on blockages (often there accumulate hair and threads).
• 🧲 Rotor magnets – they should not be crumbled.

Cleaning sensors and navigation system

Xiaomi V10 is equipped with a laser rangefinder (LiDAR) and a lot of infrared sensors that get contaminated over time, which leads to mapping errors and chaotic movement.

1. Take the LiDAR glass cover off. It's attached to double-sided tape -- put it in a silicone sucker or a mediator.
2. Wipe the glass with a microfiber wipe soaked in alcohol.
3. Clean the IR sensors (located around the perimeter of the body) with a cotton swab.
4. Blow the optical sensor (under LiDAR) with compressed air.

⚠️ Warning: Do not touch the mirror surface inside the LiDAR, this can damage the laser module. If the vacuum cleaner still "blinds" after cleaning, you may need calibration through the Mi Home application (Settings section). → Sensor calibration).

Replacement of brushes and lateral hands

Xiaomi V10 brushes are consumables that require replacement every 6-12 months.

• 🧹 The central brush does not rotate or rotates in jerks.
• 🌀 The side brushes leave traces or do not twist to the end.
• 🔊 Extraneous noise at work (screaking, knocking).

To replace:

1. Turn the vacuum cleaner over and remove the protective cover of the brush (it is attached to 2 latches).
2. Unscrew the screw in the center of the brush and remove it.
3. Install a new brush (original article: STYJ02YM-03) and lock with a screw.
4. For side brushes: press the axis of the attachment and pull the brush on yourself.

💡 Lifehack: If the central brush is clogged with hair, don't try to pull it out with your hands - use scissors to cut the hinges, then remove the remains with tweezers.

Assembly of the vacuum cleaner and check of working capacity

The assembly is done in reverse order, but there are a few critical points:

1. Make sure all connectors are tightly connected (especially engine and battery power).
2. Check the sealing gums of the dust collector - they should lie flat, without distortions.
3. Twisting screws with moderate effort - the pulling can damage the thread.
4. After assembly, perform a test run without a dust collector to make sure there is no extraneous noise.

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

• 🔋 Battery polarity – improper connection can knock out controller.
• 🔌 Contacts of the charging station – they should be clean and smooth.
• 📱 Settings in the application – sometimes you need to reconnect the device.

💡

After any disassembly, be sure to calibrate the sensors in the Mi Home app.This will take 1-2 minutes, but prevent navigation errors.
