How to open the vacuum cleaner Xiaomi: disassembly without breakdowns

Xiaomi vacuum cleaners are some of the most popular cleaning robots on the market, thanks to a combination of price, functionality and reliability. However, even the best equipment requires maintenance: cleaning brushes, replacing filters or repairing electronic components. The main problem owners face is how to open the case of a Xiaomi vacuum cleaner without damaging the latches or fillings.

In this article, we will discuss universal disassembly methods for all Xiaomi Mi Robot Vacuum, Dreame and Viomi lines, including models with laser rangefinders (LDS) You'll learn what tools you'll need, how to avoid the typical opening errors, and what to do if the vacuum cleaner doesn't turn on after disassembly, and we'll focus on hidden attachments that aren't written about in the official manuals, but that often break down when handled carelessly.

Preparation for disassembly: tools and security measures

Before you start opening the case, make sure you have everything you need. Most Xiaomi models are disassembled using the standard kit, but some (like Dreame Bot). Z10 Pro) require specialized screwdrivers.

• 🔧 Screwdrivers: cross-hairdriver (PH0, PH1), flat (1.5-2 mm), torx (T5–T8 for some).
• 🧲 Magnetic mat or screw container – to avoid losing small details.
• 📸 Smartphone for photographing the process (useful when reassembling).
• 🧴 Plastic mediator or guitar mediator - for careful clamping.
• 🔋 Multimeter (optional) – if you plan to check electronics.

⚠️ Note: Some models (e.g. Mi Robot Vacuum-Mop 2 Lite) have hidden seals on the screws of the top cover. Their damage may deprive you of warranty, even if you do not damage the vacuum cleaner itself.

Before disassembling, completely discharge the battery (up to 0%) and disconnect the vacuum cleaner from the charging station, this minimizes the risk of short circuit when working with the boards, and we also recommend disassembling on a soft surface (for example, a towel) so as not to scratch the case.

Disassembly scheme: top cover and battery access

Most Xiaomi vacuum cleaners have a dual-component body: a top cover with buttons and a bottom platform with wheels. Let's start at the top, where the battery, motherboard and Wi-Fi module are located.

Step 1 Removal of the top cover:

1. Turn the vacuum cleaner down with the buttons.
2. Unscrew all visible screws around the perimeter (usually 4-6 pieces). W10 The screws can be hidden under rubber plugs.
3. Carefully insert the plastic mediator into the gap between the top and bottom of the case. Start at the corner next to the power button, which is usually where the first latch is.
4. Smoothly guide the mediator around the perimeter, snapping the mounts. Do not force - if the lid does not respond, check if all screws are twisted.

⚠️ Attention: In models with laser rangefinder (LDS) (For example, Mi Robot Vacuum S6 MaxV) the top cover is connected to the board by a plume. Don't pull it sharply, first disconnect the plume by pulling it over the black lock.

Step 2: Removal of the battery:

• 🔋 The battery is usually fixed with 2-4 screws and connected to the board with a connector. JST 2.0.
• 📏 In some models (e.g. Dreame) D9) Battery glued to body – use plastic spatula to gently separate it.
• ⚡ Before turning off the connector, take a picture of its position - the wrong connection can bring the board down.

Disassembly of the lower part: wheels, brushes and sensors

The bottom platform of the vacuum cleaner contains wheel motors, the main brush, collision sensors and infrared sensors, and this is where dirt accumulates most often, so disassembly is required for deep cleaning or brush replacement.

Step 1: Remove the main brush:

• 🧹 Click on red or orange fixers on the sides of the brush and pull it on yourself.
• 🔧 In some models (for example, Viomi). V3) brush is mounted with a screw - it must be twisted with a screwdriver T6.
• 🧼 After removal, clean the brush shaft of wound hair and dust. Use a toothpick for hard-to-reach areas.

Step 2: Wheel removal:

1. Turn the vacuum cleaner over and unscrew the screws that hold the plastic wheel covers (usually 2 screws per wheel).
2. Remove the lids and remove the wheels along with the engines. Be careful, the engine wires are short and can break.
3. To clean the wheels, use isopropyl alcohol - it dissolves sticky dirt and does not damage the plastic.

⚠️ Note: In models with a gyroscope (such as Mi Robot Vacuum-Mop P), do not touch the sensor on the board - it is calibrated every time it is turned on, and mechanical stress can knock down the settings.

Access to electronic components: board, sensors, engines

If the vacuum cleaner doesn't turn on, doesn't charge, or malfunctions, the problem could be in the motherboard, the Wi-Fi module, or the engine drivers, and we'll figure out how to get to those components.

Step 1: Withdrawal of the motherboard:

• 📱 Disconnect all the plumes from the board (usually 3-5: buttons, LDS, motors, Wi-Fi, battery).
• 🔧 Unscrew the screws that hold the board (they can be of different lengths - remember where it stood!).
• 🧲 Carefully remove the board, do not pull the connectors - they are fragile.

Step 2: Checking the key components:

• 🔋 Charging module: check the coke on the contacts (a common cause of malfunction after long use).
• 📡 Wi-Fi antenna: in Dreame models, it often departs from the board - solder it if the connection is unreliable.
• 🔄 Engine drivers: if the vacuum cleaner moves in jerks, check the condensers on the board (bloated - replace).

In the Mi Robot Vacuum S6 MaxV and Dreame Bot Z10 Pro board control of the brush engines is located separately from the main board - it can be found under the bottom cover next to the motor.

Cleaning and replacing filters: hidden details

Xiaomi vacuum cleaners are consumables that require replacement every 3-6 months, but many users do not know that the main product is not the same as the main one. HEPA-The filter has a pre-filter and a motor filter, which also need maintenance.

Step 1: Extract HEPA-filter:

1. Open the lid of the dumpster.
2. Pull out the container and press the blue or green latch at the top of it.
3. Remove the filter and clean it with a vacuum cleaner (do not wash it with water – it breaks the structure!).

Step 2: Clean the pre-filter and engine filter:

• 🌀 The prefilter is under the main brush - remove it and pull out the mesh filter (rinse under warm water and dry for 24 hours).
• 🔄 The engine filter is hidden behind a plastic grille on the side wall of the vacuum cleaner (unscrew 2 screws). PH1).

⚠️ Note: In models with wet cleaning function (e.g. Dreame) W10) The water tank filter requires replacement every 2-3 months. Do not use a vacuum cleaner with a clogged filter, this will lead to overheating of the pump and its breakage.

💡

If you've been cleaning the filters, you've got a lot worse sucking, check the leakyness of the dumpster, and it's often because of a worn rubber pad, which you can replace with a medical syringe.

Reverse Assembly: How to Avoid Mistakes

Building a vacuum cleaner after disassembly is no less important than dismantling, and the main mistake of beginners is the wrong tightening of screws or tangled plumes, which leads to breakdowns on the first turn on.

Assembly order:

1. Make sure all rubber pads (such as a dumpster sealer) are installed in place.
2. Connect the plumes in reverse sequence. Start with the battery, then LDS, Wi-Fi, buttons.
3. Twisting the screws cross-cross to avoid skewing the body.
4. Before the final assembly, turn on the vacuum cleaner and check the operation of all functions (movement, suction, connection to the application).

⚠️ Warning: If the vacuum cleaner beeps and flashes red after assembly, this may mean:

• 🔴 Unconnected collision sensor (check the plumes in the front part).
• 🔴 Closure of the motor wheels wire (disassemble the lower part and inspect the wiring).
• 🔴 Gyroscope malfunction (calibration is required via the Mi Home app).

💡

Always check the vacuum cleaner until the final tightening of the screws - this will save time for re-disassembly.

Frequent breakdowns after disassembly and how to avoid them

Even with a careful disassembly, there is a risk of malfunctions. Let's look at typical problems and ways to solve them:

If the vacuum cleaner is not identified in the Mi Home app after disassembly, try:

1. Reset the settings to factory (press the power button for 10 seconds).
2. Reinstall the application and repeat the binding procedure.
3. Update the firmware through OTA (If the vacuum cleaner is turned on but not connected to the network).
