Disassembly of the robot vacuum cleaner Xiaomi: a complete guide with photos and tips

Xiaomi’s robot vacuum cleaners are smart assistants that save time on cleaning, but even they require periodic maintenance. Over time, dust, hair and debris accumulate inside the device, which can disable sensors, brushes or even the engine. Self-disassembly of the vacuum cleaner allows you not only to extend its life, but also save on the service center.

However, you need to carefully disassemble Xiaomi equipment: improper actions can lead to a failure of the control board, battery damage or loss of warranty (if it is still valid). In this article, we will discuss in detail how to disassemble the popular models Mi Robot Vacuum, Dreame and Viomi, what tools you will need and what to pay attention to in order not to harm the device.

If you've never done a piece of machinery before, don't worry: it doesn't require special skills, but it does require patience and care, and the key is to follow the instructions and not put too much effort into unscrewing screws or removing lids.

What Xiaomi models can be disassembled independently?

Most of Xiaomi's robot vacuum cleaners are similar in design, but there are nuances depending on the model and year of release.

• 🔹 Xiaomi Mi Robot Vacuum 1/1S/2 — Classic models with round body and removable top cover.
• 🔹 Xiaomi Dreame D9/Z10 Pro – more modern devices with improved navigation system and powerful suction.
• 🔹 Viomi V2/V3 — vacuum cleaners with the function of floor washing, requiring special attention to the water tank.
• 🔹 Redmi Robot Vacuum - budget options with a simplified design.

Laser sensor models (such as the Mi Robot Vacuum-Mop 2 Pro) are more difficult to understand because of the additional navigation modules. LDS-with a scanner (rotating "eye" on top), be careful: damage to this node will lead to loss of accuracy of mapping.

It is not recommended to disassemble on your own:

• 🚫 Vacuums are guaranteed (if you do not want to lose them).
• 🚫 Devices with obvious signs of corrosion or damage to the housing (risk of short circuit).
• 🚫 Models with non-shatterable battery (for example, some versions of Dreame Bot).

💡

Before disassembling, take a picture of the location of all screws and wires - this will help to collect the vacuum cleaner back without errors.

Preparation for disassembly: tools and security measures

To disassemble the Xiaomi Vacuum Cleaner, you will need:

• 🔧 Cross screwdriver (usually) PH0 or PH1).
• 🔧 Plastic mediator (or guitar mediator) to remove latches.
• 🔧 Tweezers – useful for extracting small details.
• 🔧 Multimeter (optional, to check the battery).
• 🔧 Wraps and alcohol to clean contacts.

Important: Batteries in Xiaomi robot vacuum cleaners often have voltage 14.4V–14.8V. Do not puncture them and do not expose them to mechanical stress - this can lead to fire!

Also prepare the workplace:

• 📌 Work on a flat, clean surface (it is better to cover the table with paper).
• 📌 Disconnect the vacuum cleaner from the charging station and remove the battery (if possible).
• 📌 Keep a screw container on hand – they are small and easily lost.

⚠️ Attention: If the vacuum cleaner fell from a height or was subjected to shocks, the contacts of the control board could move inside. In this case, the dismantling should be especially careful - sudden movements can aggravate the damage.

How to disassemble Xiaomi Mi Robot Vacuum

Let’s look at the Xiaomi Mi Robot Vacuum. 1/2 — The most common model. The process for other devices. Xiaomi/Dreame will be similar with slight differences.

Step 1: Removal of the upper cover

1. Turn the vacuum cleaner down with the buttons.
2. Unscrew 4 screws on the bottom of the case (they can be hidden under stickers or rubber legs).
3. Carefully tuck the cover with a plastic mediator, starting at the back (where the charging connector is).
4. Disconnect the power plumes from the motherboard (they are fastened with latches - do not pull the wires!).

Step 2: Removing the battery

• 🔋 The battery is attached to 2-4 screws and connected to the board with a connector.
• 🔋 Unplug the connector, then unscrew the screws and take out the battery.
• 🔋 If the battery is swelling, do not use it again!

Step 3: Access to the main nodes

After removing the cover, you will see:

• 🤖 Motherboard (with processor and modules) Wi-Fi/Bluetooth).
• 🤖 Suction engine (usually black cylinder with wires).
• 🤖 Brushes and rollers (they can be removed for cleaning without complete disassembly).
• 🤖 Collision sensors (infrared sensors around the perimeter).

Step 4: Disassembly of engine and brushes

For cleaning or replacing brushes:

1. Remove the side brush (it is attached to a latch or one screw).
2. Unscrew 2 screws that hold the main roller.
3. Take out the roller and clean it of the coiled hair (use scissors or tweezers).
4. To access the suction engine, unscrew 4 screws on its mount.

⚠️ Note: If you hear a whistling or grinding when you're working the vacuum cleaner, the problem may be the bearings of the engine. In this case, it's better to contact the service - replacing bearings requires a special tool.

Cleaning and maintenance of internal components

After disassembly, be sure to carry out a complete cleaning of all nodes:

• 🧹 Suction engine: blow with compressed air, remove dust from blades.
• 🧹 Sensors: wipe infrared sensors with a napkin dipped in alcohol.
• 🧹 Brushes: Remove the wound hair and thread, check the mobility of rollers.
• 🧹 Filters: wash HEPA-water and dry it (if it is reusable).

Pay special attention to the contacts of the battery - oxidation can lead to a bad charge. If there are traces of corrosion on the board, clean them with a stripe or alcohol.

How to check the efficiency after cleaning?

1. Collect the vacuum cleaner in reverse order.
2. Connect to the charging station and wait for full charging.
3. Run a test cleaning in Spot Cleaning mode (spot cleaning).
4. Check if there are any extraneous noises or errors in the Mi Home app.

Disassembly of Dreame and Viomi models: key differences

Dreame Robot Vacuum Cleaners (for example, D9 or Z10 Pro) and Viomi have some design features:

Dreame models often have a problem with blockages in the ducts. If the vacuum cleaner is getting worse, check:

• 🔍 A tube connecting the dust collector to the engine.
• 🔍 Filter in front of the engine (it can be clogged with fine dust).
• 🔍 The stains on the sleeves are stained over time.

For Viomi with wash function:

• 💧 Once a month, wash the tubes with acetic solution (1: 1 with water).

💡

In models with laser navigation (LDS) You can not touch a mirror or lenses – this will lead to incorrect work of cartography.

Common Mistakes in Disassembly and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakdowns.

1. too much force when unscrewing screws

The screws in Xiaomi are often made of soft metal and can break the slime.

2. Damage to plumes

The plumes that connect the board to the sensors are very fragile. Never pull the wires, always press the plastic latches.

3. Incorrect assembly of the hull

If the vacuum cleaner does not turn on or hums after assembly, check:

• 🔄 Is the battery installed correctly (contacts should fit tightly).
• 🔄 Are there no wires between the lid and the lid.
• 🔄 Whether all screws are twisted (a missing screw can cause vibrations).

4. Ignoring errors in the annex

If errors appear in the Mi Home after disassembly (for example, Error 10 - a problem with the wheel), do not rush to collect the vacuum cleaner back.

When the disassembly will not help: signs of serious breakdowns

Not all problems are solved by cleaning. If you notice the following symptoms, you may need professional repair or replacement of parts:

• ⚡ The vacuum cleaner does not charge even after replacing the battery → problem in the control board or charging module.
• ⚡ The red indicator is always on. → possible firmware failure or damage to the motherboard.
• ⚡ The suction engine does not start, but the vacuum cleaner drives → faulty motor or driver.
• ⚡ The robot moves in a circle → damaged gyroscope or odometry sensor.

In such cases, self-repair can make things worse. Contact Xiaomi Service Center or trusted craftsmen.
