Disassembly of the robot vacuum cleaner Xiaomi Mi Robot Vacuum: a complete guide with photos and expert advice

Xiaomi Mi Robot Vacuum has become an integral part of the smart home, but even the most reliable appliances require maintenance. Over time, dust, hair and debris accumulate inside the case, which reduce the suction power, and sometimes even disable the device altogether. Disassembling the vacuum cleaner yourself is not an easy task: the manufacturer does not provide easy access to internal components, and improper actions can lead to sensors breakage or damage to the printed circuit boards.

In this article, you will find step-by-step instructions for disassembling popular Xiaomi Mi Robot Vacuum models (including the Mop 2 Pro, S10, STYJ02YM And there are other tools, common mistakes, and safe cleaning tips, and we'll take you through how to get to your engine, your brushes, your battery, your sensors without damaging your fragile parts. If you've never repaired your equipment, don't worry. Our guide is designed for beginners, but contains expert nuances for experienced users.

⚠️ Warning: Disassembly of the Xiaomi robot vacuum cleaner will void the warranty (if it is still valid). Also remember that some models (such as the Mi Robot Vacuum-Mop 2 Lite) have glued body elements that are difficult to disassemble without damage.

What Xiaomi Mi Robot Vacuum models can be disassembled independently?

Not all Xiaomi robot vacuum cleaners are equally easy to disassemble.The manufacturer constantly changes the design, and if early models (for example, Mi Robot Vacuum) 1S) The new versions (like the Xiaomi Robot Vacuum-Mop 2 Ultra) are equipped with additional sensors and protection from moisture, which complicates the process.

If your model is not listed in the table, focus on the year of release: vacuum cleaners 2018-2020 (for example, Mi Robot Vacuum). 1T) They're easier to understand than modern wet cleaning devices (LDS) — damage will result in complete loss of navigation.

🔧 Tip: Before disassembling, take a photo of all the steps on your phone - this will help to properly assemble the vacuum cleaner back. This is especially true for models with a large number of sensors (for example, Xiaomi). S10+).

Preparation for disassembly: tools and security measures

To disassemble the Xiaomi Mi Robot Vacuum without damage, you will need:

• 🔧 Screwdriver kit: cross-haired (PH0, PH1), flat (1.5-2 mm), hexagon (for some models).
• 🧲 Magnetic mat or bowl: for screws (easy to lose them!).
• 📸 Smartphone: To photograph the process.
• 🧴 Plastic mediators (or guitar mediators): to separate the latches of the body.
• 🔥 Hair dryer (optional): for softening the adhesive on models with a glued body (e.g, STYJ02YM).
• 🧤 Gloves: not to leave fingerprints on the interior.

⚠️ Warning: Never use metal tools to separate plastic latches - this will lead to chipping! Also avoid heavy heat of the body with a hairdryer (maximum 60)°C) so as not to damage the sensors.

Before the start of the work:

1. Turn off the vacuum cleaner and remove the battery (if possible).
2. Make sure there is no trash in the tank - it can crumble when rolled over.
3. Place the vacuum cleaner on a soft surface (towel, foam) so as not to scratch the body.

Step-by-step disassembly of the body: from the cover to the internal components

The process of disassembly depends on the model, but the general scheme looks like this:

1. Removal of the top cover

On most models, the Mi Robot Vacuum 1S, Mop 2 Pro, the top cover is mounted on latches and 2-4 screws:

1. Turn the vacuum cleaner over and remove the side brush (it is attached to one screw).
2. Unscrew the screws under the rubber legs (they are usually 2-3).
3. Carefully tuck the cover with a plastic mediator, starting at the back (where the buttons are located).
4. Lift the lid - it should separate with a characteristic click.

Important: On Xiaomi models S10 And newer ones, there may be extra screws under the stickers, so don't pull the lid by force, check all the mounts first!

Removal of the battery

The Xiaomi Mi Robot Vacuum battery is mounted on Velcro or screws to remove it:

1. Disconnect the power connector from the motherboard (do not pull the wires!).
2. Carefully tuck the battery with a plastic spatula - it can be glued.
3. If the battery is swelling, don't use it again!

🔋 If you are planning to replace the battery, take the original battery. BMS05X0 (For the Mi Robot Vacuum 1S) or BMS09X0 (for S10). Cheap analogues are rapidly losing capacity.

Access to the engine and suction system

The engine is the most vulnerable part of the vacuum cleaner.

1. Remove the main brush (it is attached to two latches).
2. Unscrew the screws holding the dust collector (usually 3-4 pieces).
3. Remove the engine with the turbine. Be careful, it's wired to the circuit board!

⚠️ Warning: Don't try to disassemble the engine itself, you can only blow it with compressed air or brush it, and disassembly will result in a loss of leakage.

Cleaning and maintenance of internal components

After the disassembly, it's time to clean the vacuum cleaner up.

• 🌀 Turbine engine: blow with compressed air (no more than 3 bar!) or clean with a soft brush!
• 🧹 Filters: Wash under warm water (only if they are not used) HEPA — You can only vacuum them. You can dry them for at least 24 hours!
• 🔄 Brushes: remove the wound hair and threads. Use scissors for the side brush.
• 📡 Sensors: wipe infrared sensors and laser rangefinder (LDS) Don't touch the lenses with your fingers!
• 🔋 Battery contacts: clean with a swallow or alcohol from oxidation.

🛠️ Expert advice: If the vacuum cleaner has become less orientable in space, check the transparent glass of the laser rangefinder (located under the rotating "turret"). It must be cleaned every 3-6 months, otherwise the maps of the premises will be built with errors.

For models with wet cleaning function (Mi Robot Vacuum-Mop 2 Pro) additionally:

• 💧 Wash the water tank with acetic solution (1:1 with water) to remove scale.
• 🔄 Check the water supply pump - if it clogged, the vacuum cleaner won't wet the cloth.
• 🧽 Replace a microfiber wipe (it loses its properties after 50-60 cleanings).

1. The bearings of the main brush -- they could wear out.

2. Turbine fastening - sometimes the screws weaken.

Common Disassembly Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakdowns, and here are the most common ones:

⚠️ Note: If you are disassembling a model with a gyroscope (for example, Mi Robot Vacuum). S10+), Don't drop or shake the case after the board is removed. The gyro is calibrated automatically, but strong vibrations can knock it down.

Another common problem is the loss of screws. Xiaomi Mi Robot Vacuum uses screws of different lengths, and if you confuse them with places, the body may not close tightly, to avoid this, spread the screws in groups and sign them (for example, "cover screws", "engine screws").

Replacement of components: what can be changed independently?

Some parts of the Xiaomi Mi Robot Vacuum wear out faster than others and need to be replaced.

• 🔄 Side brushes - change in 2 minutes, cost 200-400 ₽.
• 🧹 Main brush – suitable for most models, priced at 500-800 ₽.
• 🌀 Filters — HEPA-filters last 6-12 months (price 300-600) ₽).
• 🔋 Battery - original costs 2000-4000 ₽, analogues are cheaper, but less durable.
• 📡 Infrared sensors – if the vacuum cleaner does not see obstacles (price 300-1000) ₽ piecewise).
• 💧 Water pump (for models with wet cleaning) - when the vacuum cleaner fails, the rag ceases to wet (price 1500-2500) ₽).

🔧 How to choose parts? Always check the article of the details on the documentation or on the official website of Xiaomi. 1S The original sidebrush has an articular ZCJY001LM, and the main brush — ZCJY002LM. When buying analogs, pay attention to the size and material – cheap brushes are often made of hard plastic that scratches the floor.

⚠️ Warning: When replacing the battery, be sure to recalibrate it in the vacuum cleaner settings (Battery item) → Otherwise, the charge indicator will show incorrect data.

1.Vacuum cleaner doesn't charge → Cleaning contacts or replacing the battery.

2. Weak suction → Turbine cleaning or filter replacement.

3. does not build a map of the premises. → Cleaning the laser rangefinder or replacing the gyroscope.

4. Not washing the floor. → Washing the pump or replacing a microfibre wipe.-->

Assembly of the vacuum cleaner after disassembly: inspection and testing

Putting the Xiaomi Mi Robot Vacuum back together is often harder than disassembling.

1. Check all the connectors - they should sit tight, without distortions.
2. Make sure the screws are twisted evenly - don't pull them over or the plastic will crack.
3. Test all functions before final assembly: Turn on the vacuum cleaner and check the rotation of the brushes. Run a test cycle of cleaning (no garbage); Check the sensors (the vacuum cleaner must respond to obstacles). LDS (Xiaomi S10) check the map construction.

Update the firmware

🔍 How do you know if the assembly was successful:

• No noise moving around the room.
• It's a good idea to get back to base.
• Do not make any extraneous sounds (squeaking, knocking).
• Show an adequate level of charge.

If something goes wrong, don't panic.

• 🔌 Connecting the battery – it should be tightly pressed to the contacts.
• 🔄 Position of brushes - they should not cling to the body.
• 📡 Fixing sensors – especially infrared and laser.
