Xiaomi Vacuum Mop Essential G1 is a popular 2023 model that combines affordable price and functionality: dry cleaning, wet cleaning, laser navigation and control through the Mi Home app. However, even the most reliable equipment requires maintenance: brushes clog, filters wear out, and the battery loses capacity.
β Cleaning turbines and fans from accumulated dust and hair
β Battery replacements (if the running time is reduced to 30-40 minutes)
β Repair of wheels or sensors after falls or collisions
β Firmware updates via the USB- port (if the OTA- update doesn't work).
In this article, unique photos of the disassembly stages with hidden latches and screws, which are not in the official documentation of Xiaomi, we will also tell you what tools you will need, how to avoid damage to plastic clips and what to do if the robot stopped turning on after assembly.
Preparation for disassembly: tools and security measures
Before you disassemble the Xiaomi Vacuum Mop Essential G1, make sure you have:
- βοΈ Plastic mediators or shoulder blades (for unscratching latches);
- βοΈ Cross screwdriver T8 and T6 (screws of different sizes);
- βοΈ Tweezers (for extraction of small parts)
- βοΈ Multimeter (to check the battery);
- βοΈ Silicone pad or scotch (so as not to lose small screws).
β οΈ Warning: Don't use metal screwdrivers to lid the lid, it will cause plastic chips. If you don't have plastic mediators, you can replace them with a credit card (but you need to be careful).
Also prepare the workplace:
- πΈ Take a picture of all screws and wires before disassembly.
- π§Ή Work on a clean surface (dust can get inside the device)
- β‘ Disconnect the robot from the charging station and wait for the battery to drain completely (this will reduce the risk of short circuit).

If you are disassembling a vacuum cleaner to replace the battery, buy the original BMS05X battery or analogue with the same parameters: 14.8V 2600mAh. Cheap Chinese batteries without protection can swell or ignite.
Removing the top cover: where are the hidden latches
Let's start with the most difficult step, the top panel separation. In the Xiaomi Vacuum Mop Essential G1, it is mounted on 4 screws (under rubber legs) and 8 plastic latches around the perimeter. Here's a step-by-step instruction:
- Turn the robot upside down with your feet and remove the side brush (it is attached to one T6 screw).
- Tuck the rubber legs (there are 4 pieces) and unscrew the T8 screws below them.
- Insert the plastic mediator into the gap between the upper and lower part of the case from the side of the power button and carefully guide it around the perimeter, snapping clips.
- When all the latches open, lift the lid, but donβt remove it completely β it is connected to the body by a tape cable (it needs to be disconnected later).
β οΈ Warning: Don't pull the lid up with force - this can tear the plume of the display or buttons. First, unplug the connector (it's under the black tape).
What to do if the latch breaks?
The photo below shows the locations of the latches (marked with red circles):
The most problematic latches are:
- At the switching button (left side);
Near the infrared sensor (right side);
Under the rear wheels (they are easy to miss).
Removal of the battery: nuances and verification
The battery in the Xiaomi Vacuum Mop Essential G1 is located at the bottom of the body and is mounted on two T6 screws and a tape connector.
- Unscrew the propellers holding the battery.
- Carefully tuck the battery on the side (it is glued to bilateral tape).
- Unplug the power connector by pulling the black plastic tongue (don't pull the wires!).
Before replacing the battery, check it with a multimeter:
| Parameter | Normal value. | Sign of malfunction |
|---|---|---|
| Unloaded voltage | 15.2β16.8V | Less than 12V - critical discharge |
| Resistance to isolation | More than 1 MOHM | Less than 500 kΞ© β the risk of short circuit |
| Leak current | Less than 50 mA | Over 100mA - battery malfunction |
If the battery is swelling, don't try to repair it - dispose of it according to the rules of your region. Lithium-ion batteries can ignite if damaged.

When replacing the battery, always use a model with the same capacity and voltage. Installing a larger battery (for example, 3000mAh instead of 2600mAh) can cause the charging circuit to overheat.
Turbine and fan cleaning: how to get to the dust filter
The turbine (suction module) in the Xiaomi Vacuum Mop Essential G1 is the most vulnerable spot, and over time it gets clogged with hair, threads and small debris, leading to:
- β οΈ Falling suction power;
- β οΈ Overheating of the engine;
- β οΈ Error E5 (system clogging).
To clean the turbine:
- Remove the dust collector and HEPA filter (they are attached to the latches).
- Unscrew the 3 T6 screws holding the plastic turbine cover.
- Remove the turbine and remove the rubber gasket (it is easy to tear, so act carefully).
- Clean the fan blades with a soft brush or compressed air.
β οΈ Warning: If the turbine is running and it is squealing or squealing, it is a sign of wear and tear on the bearings, and the entire suction module (Article XMSH05XM) will need to be replaced.
Check the integrity of the rubber gasket | Make sure the blades rotate freely | Clean the turbine power connector from dust |Turn all screws with a force of 0.3 Nm (do not pull!)

Disassembly of wheels and sensors: repair after falls
If the robot starts to go crooked, not see obstacles or fall down stairs, the problem may be:
- π Wheels (tyre wear or motor breakdown);
- ποΈ Infrared sensors (contamination or displacement)
- π‘ Gyroscope (recalibration required).
For diagnosis:
- Remove the wheels by unscrewing one T6 screw on each, and check the integrity of the gears inside.
- Clean the IR sensors (they are located in front and below) with a cotton swab with alcohol.
- If the robot is spinning in place, perform the gyroscope calibration through the Mi Home application (Settings β Sensor Calibration).
β οΈ Warning: If the robot produces a E2 error after falling, check the transparent plastic tube under the bottom cover. It may detach from the sensor.
Building a robot vacuum cleaner: how to avoid mistakes
To build Xiaomi Vacuum Mop Essential G1 need in reverse order, but there are a few critical points:
- π Connect connectors only before clicking (unpressed contact may cause an error E1);
- π Check the rotation of the wheels manually before final assembly.
- π Make sure all latches are fixed (otherwise dust will get in).
After assembly:
- Put the robot on charge and wait for the full charging-discharge cycle (this calibrates the battery controller).
- Run a test cleaning in Spot Cleaning mode to check suction and maneuverability.
- If errors occur, reset the settings via Mi Home β Settings β Reset to factory.
β οΈ Warning: If the robot does not turn on after assembly, check:
- Correct connection of the battery (the connector should sit tight);
- Integrity of the fuse on the motherboard (it can burn out with KZ);
- Short circuit in the power supply chain (call the multimeter).
Frequent Mistakes and How to Avoid Them
Even experienced users make mistakes when disassembling Xiaomi Vacuum Mop Essential G1.
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Using a metal screwdriver for the cover | Scratches, chips, broken latches | Use only plastic mediators |
| Tug-tug screws | Cracked plastic, ripped thread | Twisting with a force not exceeding 0.3 NΒ·m |
| Cleaning the turbine with water | Corrosion of bearings, short circuit | Use only dry brush or compressed air |
| Replacement of the battery without calibration | Incorrect charge display | Perform 2-3 full cycles of charging-discharge |
If the robot comes up with an E4 error after disassembly (a suction motor problem), chances are you've got the turbine connector incorrectly connected or damaged its wires.

If you are not sure about your skills, it is better to contact the service center.The cost of dismantling and cleaning in official Xiaomi services starts from 1500 rubles, which is cheaper than repairing after a failed self-attempt.
