Disassembly of the robot vacuum cleaner Xiaomi Vacuum Mop 1C: detailed instructions with repair tips

Xiaomi Vacuum Mop 1C is a popular automatic cleaning device, but even the most reliable equipment requires maintenance. Over time, dust accumulates inside, filters clog, and engines and brushes wear out. Disassembly of the vacuum cleaner may be necessary for deep cleaning, replacement of components or diagnostics of malfunctions. However, the design of Xiaomi Vacuum Mop 1C has its own features: improper actions can lead to damage to the control board, wires break or loss of the tightness of the dust collector.

In this article, you'll find step-by-step disassembly instructions with photos of key steps, a list of tools you need, and unique tips for avoiding common errors. We'll also look at which parts you can clean yourself, and when you should contact a service center. If you've never taken apart robot vacuum cleaners, start by learning the structure of the device, which will help you understand how to avoid damaging fragile elements during dismantling.

Preparation for disassembly: tools and security measures

Before you start disassembling the Xiaomi Vacuum Mop 1C, make sure you have everything you need. Lack of the right tools can cause plastic latches to break or scratch the body. Here is the minimum set:

• ✅ Plastic mediators (2-3 pieces) - for careful separation of the latches of the body.
• ✅ Cross screwdriver (size) PH0 or PH1) — for the lower-lid screws.
• ✅ Tweezers – to extract small parts (for example, springs or sealing rings).
• ✅ Multimeter – to check the integrity of wires and contacts (optional, but recommended).
• ✅ Microfiber wipes – to clean internal surfaces from dust.
• ✅ Container for screws - so as not to lose small fasteners.

Also, prepare the workplace: a flat surface (better cover it with a light cloth so as not to lose details) and good lighting. If you disassemble a vacuum cleaner, buy it in advance. HEPA-filter ZNMS01WM) and side brushes (article) ZNMS02WM) — It is recommended to replace them every 6-12 months.

⚠️ Warning: Do not disassemble the vacuum cleaner immediately after cleaning! Let it cool for at least 30 minutes - this will prevent the plastic parts from deforming from changing temperatures. Also turn off the battery (instruction below) to avoid short circuits.

Removal of the upper cover and access to the battery

The first stage of disassembly is to dismantle the top cover. On the Xiaomi Vacuum Mop 1C, it is mounted on 4 hidden latches and one screw under the plug. Here's how to do it correctly:

1. Turn the vacuum cleaner up with the buttons and remove the dust collector (click on the Release button on the side).
2. Put a plastic plug near the charging connector (it hides the screw) - use a mediator or nail.
3. Unscrew the PH0 screw and put it in the container.
4. Carefully walk the mediator around the perimeter of the lid, pressing the latches. Start with the upper right corner (the latches are weaker there).

After removing the lid, you will see the battery (lithium-ion, 2600 mAh, 14.4 V) It must be turned off before further disassembly - even when switched off, the circuit board is supplied with voltage!

• ⚡ Disconnect the white power connector from the board (it is located next to the battery).
• ⚡ Insulate battery contacts with tape to avoid accidental circuiting.

If you notice a battery bloating, don't continue disassembling it, it's a sign of malfunction, and it needs to be replaced, and a bloated battery can ignite when it's mechanically exposed.

Dismantling the main board and sensors

The main control board in Xiaomi Vacuum Mop 1C is responsible for navigation, communication with the application and control of the engines.

1. Unscrew 3 screws (two on the sides and one in the center) of the board mount.
2. Carefully raise the charge for the edges - it is connected to the body 4 plumes: 📡 Wi-Fi/Bluetooth-module (black connector). 🔍 Laser rangefinder sensor (white connector). 🔋 Powering engines (red connector). 🎛️ Control buttons (gray connector).

Disconnect the plumes by pulling the plastic tongues (don't pull the wires!).

Pay special attention to the laser rangefinder (under a transparent cap) that is calibrated in the factory, and its displacement will lead to incorrect navigation of the vacuum cleaner. If you do not plan to replace the sensor, do not remove the cap — just clean it from the outside with a napkin.

⚠️ Warning: The board has capacitors that can hold up to 5 minutes after the power is turned off!

Disassembly of the dust collector and filtration system

The Xiaomi Vacuum Mop Dust Collector 1C It consists of several parts: the main container, HEPA-filter, pre-cleaning mesh and turbine engine to disassemble it completely:

1. Press the red button on the back wall of the dust collector and remove the cover.
2. Extract. HEPA-filter (gray cylinder) and mesh (metal mesh).
3. Unscrew 2 screws at the bottom of the container (under the rubber pad).
4. Carefully disconnect the halves of the body - inside is a turbine engine.

When cleaning the shaft, look for bearings (small metal rings around the edges) if they jam or luft, they need to be replaced. It is not recommended to lubricate the bearings, this will lead to adhesive dust.

To replace the main brush (ZNMS05WM):

1. Remove the locking rings from the shaft (use tweezers).
2. Move the brush to the side and remove it from the axle.
3. Install a new brush and fix it with rings.

⚠️ Warning: Do not use metal tools to remove the locking rings, they can scratch the shaft. If the ring does not respond, moisten it. WD-40 And wait 5 minutes.

💡

Before installing a new brush, check it for backlash: swing it to the sides. If the backlash is more than 1 mm, the brush is defective, replace it with a warranty.

Cleaning and maintenance of the washing module

Xiaomi Vacuum Mop 1C is equipped with a wet cleaning system that requires regular maintenance.

• 💧 Water tank (capacity 200 ml).
• 🧹 Microfibre wipe (replaceable).
• 🔄 Water supply pump (located under the tank).
• 📏 Water level sensor (float mechanism).

To clean the module:

1. Remove the tank by pressing the blue button at the back.
2. Wash it with warm water (no detergents!) Pay special attention to the water supply tube - it is often clogged with scale.
3. Check the pump: blow into the tube, the air must pass freely. If the pump does not pump water, it must be replaced (ZNMS06WM article).

Wash the wet wipe manually at a temperature not higher than 40°C. Do not use bleach or air conditioners - they destroy the microfiber. If the wipe has lost its absorbent properties (water rolls in droplets), it is time to replace it.

💡

Regular cleaning of the detergent module (once a month) prevents overgrowth of the tubes by scale and increases the life of the pump by 30-40%.

Assembly of the vacuum cleaner and check of working capacity

The Xiaomi Vacuum Mop 1C should be built in reverse order, and here are the key points to consider:

• 🔩 Screw them: twist them cross-cross to avoid skewing the body.
• 🔌 Trains: Connect them before clicking – an unpressed connector can cause an Error 10 error (no communication with sensors).
• 🔋 Battery: Before connecting, check that the contacts are dry and clean.
• 🧲 Latches: make sure that all latches of the body are fixed (check by pressing the lid around the perimeter).

After assembly, perform a test cleaning:

1. Turn on the vacuum cleaner and check the indicators (should burn green).
2. Start cleaning in Spot Cleaning mode - so it is easier to evaluate the work of brushes and suction.
3. Check the detergent module: pour water into the tank and make sure it is evenly distributed over the napkin.

If the vacuum cleaner gives an error (for example, Error 5 - a problem with the side brush or Error 9 - a jamming of the shaft), repeat the disassembly and check the corresponding nodes. Error codes for Xiaomi Vacuum Mop 1C can be found in the official documentation or in the Mi Home application.
