How to disassemble the robot vacuum cleaner Xiaomi Vacuum Mop P: instructions with photos and nuances

Xiaomi Vacuum Mop P is a popular model among smart appliance owners, but even the most reliable device requires maintenance. Dust, hair and small debris accumulate over time not only in the container, but also inside the case: on the fan, sensors and boards. Disassembly of the vacuum cleaner may be necessary for deep cleaning, battery replacement, wheel repair or fault diagnosis. However, Xiaomi design is not designed for frequent disassembly – improper actions will lead to break latches or damage to plumes.

In this article, you will find a step-by-step photo guide that will help you carefully disassemble the Vacuum Mop P without specialized tools. We will tell you which mounts are the most fragile, how to avoid errors when removing the lid, and what to do if the vacuum cleaner stopped turning on after dismantling. And also unique tips for cleaning the laser sensor LDS, which often fails due to dust.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need. Xiaomi Vacuum Mop P is assembled on plastic latches and screws with custom heads, so a regular screwdriver may not fit.

• 🔧 A set of screwdrivers with bits T5, T6 and T8 (torx) - without them you can not unscrew the bottom cover.
• 🧲 Magnetic mat or screw container – to avoid losing small details.
• 📸 Smartphone for photographing the dismantling stages (useful when reassembling).
• 🧴 Isopropyl alcohol (70%+) Cotton swabs – to clean contacts and sensors.
• 🧤 Antistatic bracelet (optional) – protects the boards from static electricity.

Important: Xiaomi Vacuum Mop P has a lithium battery that can ignite if damaged. If you notice a bloated battery, don't disassemble the vacuum cleaner yourself. Contact the service center. Also avoid disassembly in humidity above 60%, which increases the risk of contact corrosion.

⚠️ Warning: If the vacuum cleaner is warranty, disassembly will void it. Check the warranty period in the Mi Home app (Device → Warranty).

Removing the top cover: where the latches are hidden

So the hard part is, you take the top panel off, where the power button and the laser LDS sensor are, and the key is not to break the plastic locks.

1. Turn off the vacuum cleaner and turn it down with the button.
2. Unscrew the 4 T6 screws around the perimeter of the upper cover (they are hidden under the rubber legs - gently tuck them into a flat screwdriver).
3. Take a plastic blade (or mediator) and start pulling the cover on the side of the rear wheel - there the latches are weaker.
4. Move around, alternately releasing the locks. If the lid doesn't lend itself, don't push harder, check if all screws are unscrewed.

Under the lid, you'll see:

• 🔋 Battery (twisted by T5 screws).
• 📡 Wi-Fi module and antenna.
• 🔄 Control board with sensor connectors.

💡

If the latches break, don't panic. They can be replaced with AliExpress latches (see "Xiaomi Vacuum Mop P latches" if you want them to), and don't lose the springs from the power button!

Notice the plume of the laser sensor, which is attached to the board with a lock connector. To disconnect it, carefully lift the black latch up (don't pull the wires!). If you damage the plume, the sensor will stop rotating, and the vacuum cleaner will "blind" when cleaning.

Removal of the battery: nuances and risks

The battery in Xiaomi Vacuum Mop P is one of the most vulnerable places. Over time, it loses capacity, and the vacuum cleaner starts to work 10-15 minutes instead of the stated 110 minutes. Replacing the battery will cost 2000-3000 ₽, but you can do it yourself.

Procedure:

1. Disconnect the power connector from the board (it is white, with 4 contacts).
2. Unscrew 3 T5 screws that lock the battery.
3. Carefully raise the battery -- there may be double-sided tape underneath. Don't pull sharply!

⚠️ Warning: If the battery is swelling, don't try to puncture or compress it. Lithium-ion batteries can ignite if damaged. Dispose of it at special reception points (addresses can be found on the Ecosystem website).

When installing a new battery, make sure that the contacts are not oxidized. If you notice a greenish coating, clean them with a blower or alcohol. Also make sure that the thermal sensor (thin white wire) is connected to the board - without it, the vacuum cleaner will not charge.

Cleaning internal components: what and how to clean

The main reason for the Xiaomi Vacuum Mop P disassembly is deep cleaning, and the dust and hair accumulate in the most unexpected places, impairing performance.

• 🌀 Turbine (fan): Removed after unscrewing 2 screws T8 Clean with a soft brush, avoiding damage to the blades.
• 👁️ Laser sensor LDS: wipe only with a dry wipe -- alcohol can damage the lens. Dust on the sensor causes error Laser radar blocked.
• 🧲 Collision sensors (front): Check if they're not dirty. If the vacuum cleaner can't see the obstacles, that's the problem.
• 🔄 Brushes and rollers: Remove the wound hair with scissors and grease the axles with silicone lubrication.

To clean the boards, use cotton swabs dipped in isopropyl alcohol. Keep the fluid out of the connectors.

• Contacts of the charging station (oxidation leads to poor contact).
• I will connect the gyroscope – if the vacuum cleaner is going crooked, the problem may be in it.

If the vacuum cleaner produces a fan error (50005), chances are you have damaged the turbine wires. Check their integrity with a multimeter (resistance should be ~10 Ohms).

Disassembly of wheels and side brush: typical problems

The wheels and the side brush are the most "suffering" parts, and the wheels eventually start to slip or creak, and the brush stops rotating, and we'll figure out how to service them.

Front wheel:

1. Unscrew 1 T6 screw from the side.
2. Remove the wheel from the axle - it is attached to the latch.
3. Clean the axle of the old lubricant and apply a new one (such as Silicone Grease).

Side brush:

• Remove the brush by pulling it up.
• Check the gear drive - it is often clogged with hair.
• If the brush is not rotating, replace the motor (cost ~800 ₽).

⚠️ Warning: If the wheel is tight after assembly, check if the axle is skewed. Also make sure that the Hall sensor wires (responsible for taking into account the distance traveled) are not clamped.

Wheel screeching is often caused by wear and tear of rubber gaskets, which can be replaced with similar ones from other Xiaomi models (for example, from the Vacuum Mop 2 Pro), if the original ones can not be found.

Diagnostics of malfunctions after disassembly

If after assembly the vacuum cleaner does not turn on or malfunctions, use this table for diagnosis:

If the vacuum cleaner squeaks when it's turned on, but it doesn't start cleaning, the problem is in the control unit.

1. Press the power button for 10 seconds.
2. Connect to charging and hold the button for another 5 seconds.
3. Let go - the vacuum cleaner has to reboot.

💡

If the vacuum cleaner is not visible in the Mi Home app after disassembly, reset it to factory settings: hold the on button and the Spot Clean button simultaneously for 20 seconds.

Cleaning the vacuum cleaner: how to avoid mistakes

To assemble Xiaomi Vacuum Mop P need in reverse order, but there are a few critical points:

• 🔌 Trains: Make sure all connectors are snapped to the end (especially LDS and the gyroscope).
• 🔋 Battery: Check polarity—red wire to +, black to—.
• 🔄 Cover: Start snapping from the side of the power button, then move around in a circle.
• 🧹 Brushes: Once installed, scroll them manually - they should rotate freely.

After assembly, perform the test:

1. Check the charging – the indicator should be on blue.
2. Start cleaning in Spot Clean mode - the vacuum cleaner should go in a spiral.
3. Look at the Mi Home app – if there are errors, they will show up in the Status section.

If the vacuum cleaner is humming after assembly, but does not move, check:

• Connection of wheel motors (J1 and J2 connectors on the board).
• Integrity of the belt transmission (at the main brush).
