Disassembly of the robot vacuum cleaner Xiaomi Vacuum Mop: instructions with photos and nuances

The Xiaomi Vacuum Mop robot vacuum cleaner (including the Mi Robot Vacuum-Mop P, Mi Robot Vacuum-Mop 2 and other versions of the series) is a smart device that combines dry and wet cleaning functions. However, over time, even the most reliable equipment requires maintenance: brush cleaning, changing filters or repairing internal components. Many users are afraid to disassemble the device themselves, fearing fragile parts or losing warranty. In fact, with the right approach, disassembly is no more difficult than replacing the battery in the remote control - the main thing is to know the sequence of actions and use the appropriate tools.

In this article, we will discuss in detail how to disassemble the Xiaomi Vacuum Mop for cleaning or minor repairs without damaging the case or electronics. You will learn what screwdrivers you will need, how to remove the bottom cover without scratching, and what to do if the device stopped charging or does not collect garbage well. And we will talk about hidden “traps” that the manufacturer does not specify in the official documentation – for example, why you can not use metal tools to remove clips or how to not lose small springs when disassembling a side brush.

If you've never disassembled appliances, don't worry: in Xiaomi Vacuum Mop, all mounts are standard, and most parts are fixed on latches or screws under the cross screwdriver. The main rule is not to apply excessive force. The plastic body of the device is durable, but when exposed to rough impact can crack, especially in the places where the sensors are attached.

1. Disassembly preparation: tools and precautions

Before you start disassembling, make sure you have everything you need, and here is the minimum toolkit you'll need for most operations:

• 🔧 Screwdriver cross (size) PH0 or PH1 — suitable for most screws in the body).
• 🔧 Plastic mediator (or guitar mediator) – for accurate clip-clicking.
• 🧲 Magnetic substrate or bowl - so as not to lose small screws and springs.
• 📸 Smartphone for photography – fix the location of parts before taking off.
• 🧴 Isopropyl alcohol (70%+) — Cleaning contacts and sensors.

Also prepare the workplace: a wide dining surface covered with soft cloth (such as a towel) so as not to scratch the body of the vacuum cleaner. If you are disassembling the cleaning device, prepare cotton swabs, soft brush and vacuum cleaner with a narrow nozzle - they will help remove dust from hard-to-reach places.

⚠️ Warning: Do not use metal objects (knives, flat sting screwdrivers) to snap clips! plastic latches in Xiaomi Vacuum Mop are fragile and can break if sloppy. If there is no mediator on hand, use a plastic card or even a tablespoon (wrapped with cloth).

If you are disassembling the vacuum cleaner due to charging problems, pre-check:

1. Cleanliness of contacts at the docking station and the robot itself (wipe with alcohol).
2. Integrity of the power cable (especially in bending places).
3. Stress in the socket (sometimes the problem lies not in the vacuum cleaner, but in the network).

💡

Before disassembling, completely discharge the vacuum cleaner battery (up to 0%) and leave it off for 10-15 minutes, which minimizes the risk of short circuits in case of accidental contact grazing.

Removal of the bottom cover: access to brushes, filters and battery

The bottom cover of the Xiaomi Vacuum Mop is mounted on 4-6 screws (depending on the model) and several plastic clips. To remove it, follow the following steps:

1. Turn the vacuum cleaner over and place it on a soft surface (such as a towel).
2. Twisted all the screws around the perimeter of the lid (usually located under rubber legs or stickers). In Mi Robot Vacuum-Mop 2 Pro models, there can be an additional screw under a round round round round round around the main brush.
3. Carefully apply the cover to the mediator, starting from one of the corners. Clips are usually located on the sides and closer to the front (where the collision sensor is located).
4. Lift the lid and put it aside. Be careful: it may be connected to the wires of the drop sensor (in some models).

After removing the cover, you will have access to:

• 🔄 Main brush (it can be removed by pressing the locks on the sides).
• 🧹 Side brush (attached to one screw and latch).
• 🔋 Battery (in most models - removable, but requires disconnection of the plume).
• 🌀 Fan and filter (located in the rear part).

⚠️ Note: In models with automatic cleaning mode change (such as Xiaomi Vacuum Mop 2 Ultra), there may be an additional humidity sensor under the lid. Don't pull its wires - they easily detach from the board!

If you're disassembling a fan cleaner, look at the mounting. Most models have a fan with a single screw and a plastic nut (which needs to be unscrewed counterclockwise). Use a soft brush to clean the blades, because metal objects can damage the balance, which will lead to increased vibration.

Top Disassembly: Access to Electronics and Sensors

If you need to get to a motherboard, sensors, or Wi-Fi module, you need to remove the top cover, which is more difficult than disassembling the bottom, because there are more plumes and fragile parts.

Algorithm of action:

1. Remove the dust collector (click on the lock button and pull up).
2. Unscrew the screws under the dust collector (usually 2-3 pieces).
3. Carefully tuck the top cover with a mediator starting at the back (where the power button is located). The clips are stiffer, so you'll have to put in a little effort.
4. Disconnect all the plumes from the motherboard. They're fixed by small latches -- put a nail on them or a plastic spatula.

Under the top cover you will find:

• 📡 Wi-Fi module (usually screwed to the board with two screws).
• 👁️ Lidar (laser sensor) – don’t touch its lens!
• 🔊 Dynamics (can be glued or fixed to latches).
• 🔋 Battery (in some models attached to the upper part of the body).

In Xiaomi Vacuum Mop 2 Pro and later, the motherboard can be covered with heatpaste to cool the processor. When disassembling, do not touch it with your fingers - skin fat worsens thermal conductivity.

4. Cleaning and replacement of brushes, filters and other consumables

One of the most common reasons for disassembling Xiaomi Vacuum Mop is to replace consumables, the manufacturer recommends changing or cleaning the following items every 3-6 months (depending on the intensity of use):

• 🧹 Side brush – accumulates hair and threads that make it difficult to spin.
• 🌀 Main brush - rubber wears out and bearings clog with dust.
• 🔄 Filter HEPA — It is clogged with fine dust and loses throughput.
• 💧 Mope nozzle (in models with wet cleaning) - the fabric is washed off and ceases to absorb water.

For cleaning the main brush:

1. Remove the brush by pressing the locks on the sides.
2. Remove the wound hair and threads from the shaft (use pliers or scissors).
3. Wash the brush under warm water with soap, then dry for at least 24 hours.
4. Lubricate the bearings with silicone lubrication (1-2 drops on each side).

Filter HEPA cleaned as follows:

1. Remove the filter from the case (usually located next to the dust collector).
2. Tap them carefully on a hard surface to remove the large dust.
3. Vacuum the filter at minimum power (do not use water – it will spoil the material!).
4. If the filter is heavily contaminated, replace it with a new one (original filters for Xiaomi are labeled as "S" or "S" or "S" or "S" W109 or W110).

⚠️ Warning: Never use water or detergents to clean the filter! the wet filter loses its properties and can cause error E3 (oscillation of the duct) or E4 (fan trouble).

💡

Regular cleaning of brushes and filters extends the life of the vacuum cleaner by 30-50%. If you ignore this procedure, the fan motor will work for wear, which will lead to its failure in 1-2 years.

5. Battery Replacement: When and How to Do It

The battery in Xiaomi Vacuum Mop is one of the most vulnerable components, it lasts for 2-3 years of active use, after which the operating time is reduced to 10-15 minutes. If the vacuum cleaner begins to discharge quickly or does not hold a charge at all, it is time to think about replacing it.

Signs of a worn-out battery:

• ⚡ The working time was reduced to 20-30 minutes (at the initial 90-120).
• ⚡ The vacuum cleaner does not charge to 100% or shuts down at 80-90%.
• ⚡ The battery swelled (see by the deformation of the cover).
• ⚡ The device is arbitrarily switched off during cleaning.

For battery replacement:

1. Remove the lower or upper cover (depending on the model).
2. Disconnect the battery plume from the motherboard (remember the polarity!).
3. Unscrew the screws that lock the battery (usually 2-4 pieces).
4. Remove the old battery and install a new one (recommended models: LBXM08L32 or LBXM08L33 for most modifications).
5. Connect the plume and assemble the body in reverse sequence.

After the battery replacement, calibration may be required:

1. Completely discharge the vacuum cleaner (until automatically shut down).
2. Put it on the charger and wait 100%.
3. Repeat the discharge / charge cycle 2-3 times.

💡

When buying a new battery, pay attention to its capacity and voltage.The original batteries for Xiaomi Vacuum Mop have voltage 14.4V or 14.8V 3200-5200 mAh. Batteries with other parameters can disable the charging controller!

6. Removal of common errors after disassembly

If the vacuum cleaner is not doing well after assembly, you've probably made one of the common mistakes. Here are the most common problems and solutions:

If the vacuum cleaner makes a mistake E1 (The problem with the drop sensor, most likely, you forgot to connect its plume or incorrectly installed the sensor itself. In Xiaomi Vacuum Mop 2 models, the drop sensor is located in front under the bottom cover and is attached to two screws. Make sure it fits tightly to the body – even a small gap can cause false positives.

Another common problem is that the vacuum cleaner doesn't return to base, and it could be related to:

• 🔋 Replace or calibrate your battery (replace or recharge it).
• 📡 Interference for Wi-Fi signal (move base to more open place).
• 👁️ Lidar or sensor contamination (wipe them with a napkin dipped in alcohol).

7.When disassembly didn't help: diagnosing serious breakdowns

If you've had some problems after dismantling and cleaning, it's probably a serious breakdown in the electronics, and here are some signs you should contact the service center:

• 🔥 Vacuum cleaner smokes or smells of burns - a sign of a short circuit or a burnt engine.
• 💥 Battery swollen or leaking - urgent replacement is required.
• 🤖 The robot moves in jerks or does not obey the command - it is possible to break the motherboard or wheel motors.
• 📛 Mistakes are always burning. E6, E7, E9 — Problems with electronic components (gyroscope, lidar, controller).

Some breakdowns can be diagnosed independently:

• Fan motor check: When the vacuum cleaner is turned on at maximum power, it should give a smooth hum. If you hear grinding or vibration, the bearings are likely worn out.
• Wheel motor test: lift the vacuum cleaner above the floor and turn on the cleaning mode. The wheels must rotate synchronously. If one wheel is not spinning or moving in jerks, the problem is the engine or gears.
• Diagnostic lidar: run a vacuum cleaner in a dark room, and if the lidar is not rotating or is shining dim, it needs to be replaced.

To replace the motherboard or motors will require:

• 🔧 soldering iron (for welding plumes in some models).
• 🛠️ Set of screwdrivers (including torx) T5 and T6 squirrel).
• 🔍 Lupe or magnifying glass - for working with small details.

⚠️ Warning: If you're not sure about your soldering skills, don't try to replace your motherboard or motors yourself! soldering errors can cause the device to fail completely.
