Disassembling the Xiaomi mop: a complete guide with photos and repair tips

Xiaomi mops are smart cleaning assistants that combine technology and practicality. However, even the most reliable device requires maintenance: cleaning, replacing consumables or minor repairs. It is easy to disassemble a Mi Mop or Dreame mop yourself if you know the design and avoid typical errors. In this article, we will discuss how to properly dismantle the case, remove the battery, replace the nozzle or motor, and provide tips for caring for parts.

It's important to understand that mop models differ in design, like the Xiaomi Mi Mop 2C has a removable battery, and the Dreame V9 has a built-in battery, and some versions have electronic humidity control, which adds to the complexity of disassembling, and we've taken these nuances into account and prepared a universal instruction manual that takes into account the features of popular models. If you've never disassembled household appliances, don't worry: the process does not require special skills, but it will require accuracy and patience.

Preparation for disassembly: tools and security measures

Before you start, make sure that the mop is completely discharged, which will prevent accidental switching on while working with electronic components, and also prepare the workplace: a table with good lighting and no unnecessary items.

• 🔧 Screwdriver cross (usually) PH2) — hull-rotor.
• 🔨 Plastic mediator or guitar mediator – to separate latches.
• 🧲 Magnetic screwdriver or tweezers - so as not to lose small screws.
• 📸 Smartphone - for photographing the dismantling stages (useful when assembly).
• 🧴 Alcohol or contact cleaner - for cleaning boards and connectors.

If you are planning to replace parts, pre-order original parts. For example, for Xiaomi Mi Mop 2 Pro fit nozzles with the article DMY-MOP01, and for Dreame V10 – DRM-V10-001. Beware of counterfeits: non-original parts may not fit in size or damage the mechanism.

⚠️ Warning: Do not use metal tools to disconnect plastic latches, this may leave scratches or break the mounts. If the latches do not respond, check if all screws are twisted.

Disassembly of the body: step-by-step instructions with a photo

To start with, the main body is dismantled. Most Xiaomi models have a two-piece design: a top with a handle and a bottom with a motor and a nozzle.

1. Remove the nozzle for washing the floor, pulling it up (on some models there is a fixture - click on it).
2. Turn over the mop and find the screws on the bottom panel, usually 4-6 of them hidden under rubber plugs (take care of them with a knife).
3. Turn all the screws out and put them in a separate container. Dreame models can have screws of different lengths — remember where you were.
4. Put a plastic mediator in the gap between the halves of the body and carefully separate them as you move around the perimeter. Don't put too much effort into the latches - the latches are fragile!

Once the body is separated, you'll see the internals: the battery, the control board, the motor and the wires. In electronically controlled humidity models (like the Mi Mop 2 Pro), the board can be covered with a silicone pad — don't damage it when cleaning.

Battery Dismantling: Nuances for Different Models

The battery is one of the most vulnerable parts of the mop, and over time it loses capacity, and the device starts to work less time. In Xiaomi Mi Mop 2C and Mi Mop 1T, the battery is removable, and in Dreame V9/V10, it is soldered into a board. Let's consider both options.

For a removable battery:

1. Disconnect the power connector from the board (usually it is white or black).
2. Unscrew the battery locking screws (can be hidden under the sticker).
3. Carefully remove the battery by pulling the plastic handle (if any).

For soldered battery (Dreame):

• 🔥 Use a soldering iron with a thin sting (power no more than 30 W).
• 🔌 Seal off the wires, having previously photographed their location.
• 📏 The new battery should have the same parameters: voltage 3.7V and a capacity of at least 2000 mAh.

⚠️ Warning: When soldering, do not overheat the board - this can damage the charging controller. Use flux solder and avoid short circuits.

💡

If the mop doesn't turn on after the battery is replaced, check the polarity of the connection. Often manufacturers mark "+" and "-" on the board and battery, but sometimes the marking is erased.

Replacement and Replacement of Motors: When It Is Necessary

The Xiaomi mop motor is responsible for rotating the nozzle and spraying water, and if the device becomes less pressable or makes extraneous sounds, it could be because the gears wear out or water gets into the winding, and we can figure out how to diagnose and fix the problem.

Signs of engine failure:

• 🔊 Screaming or vibration when working.
• 💦 Weak water pressure or lack thereof.
• 🔋 Fast battery discharge (the engine consumes more energy).

To clean the engine:

1. Disconnect the wires from the motor (usually red and black wires).
2. Unscrew the screws of the mount and remove the motor along with the gears.
3. Wash the gears with warm water and soap, remove dirt from the shaft.
4. Blow the engine with compressed air (do not use wet cleaning!).

If the engine is burned, replace it with a new one. The original parts for the Mi Mop can be found in the DMY-MOTOR01 article, for the Dreame - DRM-MOTOR-V9. When you install the new engine, check the compatibility of the connectors.

Replacement of the nozzle and water supply system

The nozzle is a consumable that requires regular replacement (every 3-6 months). Xiaomi models use a microfiber fiber system with a velcro or latch attachment, and if the nozzle wears out or no longer absorbs water well, it can be replaced yourself.

How to remove the old nozzle:

1. Pull the nozzle up while holding the mop body.
2. If you are fastened to the Velcro, carefully separate the fabric from the base.
3. Wash the base under running water, removing the remains of dirt.

For electronically controlled models (such as the Mi Mop 2 Pro), also check the condition of the water supply tubes, which can clog or crack, to replace them:

• 🔍 Disconnect the tube from the pump (usually fixed with a plastic clamping).
• 🛠️ Pull out the old pipe and install a new one, having previously lubricated with silicone lubricant.
• 💧 Check the tightness by pouring water into the tank.

Diagnostics of the management board: common breakdowns

The control board is the mop's brain, which controls the motor, the pump, and the display, and if the device doesn't turn on, doesn't respond to buttons, or is out of order, it could be a problem with the board, and let's look at the typical problems and how to fix them.

Symptoms of fee malfunction:

• 🔄 The mop spontaneously turns on/off.
• 🔋 The charging indicator does not burn or flashes red.
• 💧 The pump is running, but the motor does not rotate the nozzle (and vice versa).

For diagnosis:

1. Visually inspect the board for darkened or bloated elements (capacitors, resistors).
2. Check the integrity of the tracks with a magnifier – sometimes they burn out from a short circuit.
3. Use a multimeter to check the voltage at key points (e.g., the output of the stabilizer).

If you find a burned item, you can replace it yourself (if you have soldering experience) or contact the service center. For Xiaomi models, original boards are rarely sold, but you can find compatible counterparts from Chinese suppliers (for example, on AliExpress on request Xiaomi Mi Mop PCB).

💡

If the board is damaged by water, do not turn on the mop until completely dry (at least 24 hours).

Assembly of mop after disassembly: tips and verification

Assembly is as important as disassembly, and improperly installed parts can lead to failure or malfunction.

• 🔄 Collect the mop in reverse order using photos taken during disassembly.
• 🔧 Twisting the screws cross-cross to avoid skewing the body.
• 🔌 Before final assembly, check the operation of all buttons and motor.
• 💧 Pour water into the tank and make sure there are no leaks.

After assembly, perform a test run:

1. Turn on the mop and check the rotation of the nozzle.
2. Activate water spraying (if there is such a function).
3. Look, there's no extraneous noise.

⚠️ Warning: If the mop doesn't work after assembly, don't panic. Re-disassemble it and check: Connection of connectors (especially battery and motor), no clamped wires.
