Modern cleaning devices like the Xiaomi Vacuum Mop G1 have proven to be reliable assistants, but even the best equipment requires maintenance over time. Falling suction power, extraneous noises when operating or battery failure are signals that your gadget needs a deep technical inspection. Unlike surface cleaning of the container, full disassembly allows you to get to hidden nodes, which often cause failures.
The process of dismantling this device does not require super-complex equipment, but it is very accurate. Inside the case, there is a dense layout, where each screw and plume have their place. Removing the bottom cover of the G1 model is done without using a screwdriver, because it is held on hidden latches and magnetic retainers. Wrong effort can lead to plastic breakage, so it is important to act consistently and carefully to study each step before work begins.
In this article, we will discuss in detail the algorithm of actions necessary to safely open the case, learn how to properly remove the battery for replacement, clean the engine turbine and maintain the side wheels. Follow the recommendations described below will help to extend the life of your device and avoid expensive visits to the service center.
Preparation of the workplace and the necessary tool
Before you start taking action, you need to organize the space. The work surface should be well lit so you can distinguish between small parts and fasteners. Dust and fine debris that will inevitably be extracted from the gut of the robot should not mix with dirt on the table, so put a clean cloth or an antistatic mat.
You'll need the minimum toolkit that most home craftsmen have to work with, and the basic toolkit requirement is sizing accuracy so you don't rip off the screws or damage the plastic latches, and you're not allowed to use inappropriate items like kitchen knives because they can damage the case.
Collect the following set before starting the procedure:
- 🔧 Cross-sized screwdriver PH1 or PH2 (preferably magnetic)
- 🛠️ Plastic spatula (poodger) or old plastic card
- 🧤 Antistatic gloves (optional, but desirable)
- 📱 Smartphone with camera (for fixing disassembly stages)
Pay special attention to lighting. Shadows can hide important design details, such as hidden screws under stickers. If you have the opportunity, use a desk lamp with cold light, which heats plastic parts less when working longer.
⚠️ Warning: Before starting any work, be sure to disconnect the robot vacuum cleaner from the charging station and turn it off with a power button.
The procedure should be strictly regulated so as not to lose small cogs, it is recommended to use a magnetic tray or a container with sections where you will fold the fastener in order of its extraction, which will save you time when you reassemble.
Dismantling of external elements and bottom panel
We start the disassembly process at the bottom of the device, where the main nodes are located, and the first step is always to remove the dust collector and water tank, if it's installed, which will free up access to the internal machinery and reduce the weight of the device when you manipulate it.
Turn the Xiaomi Vacuum Mop G1 upside down. Carefully look at the perimeter of the bottom platform. Unlike many other models, there are no visible screws holding the main cover. Fixing is done by the latch system in a circle. Carefully swipe the plastic blade around the junction between the top and bottom of the body, starting from the wheels.
Act without bigotry: if plastic resists, you missed the locking element. Sometimes the screws can be hidden under rubber plugs or stickers, although in the G1 model the emphasis is on clips. Once all the latches are snapped, remove the bottom panel.
☑️ Checklist before removing the cover
Once you remove the panel, you'll have access to the wheels, the side brush and the battery. Don't pull the wires out immediately. First, visually assess the plumes and connectors, and often this is where the most dust and hair accumulates, which can interfere with normal contact.
Replacement of the battery and maintenance of contacts
One of the most common reasons for turning to disassembly is to replace the power source. Over time, lithium-ion batteries lose capacity, and the robot starts to work much less than the stated time or completely stops charging. In the G1 model, the battery is a block enclosed in a plastic case with out contacts.
To remove the battery, you have to disconnect the power connector from the motherboard. Be very careful: the connectors are quite fragile. Don't pull the wires, hold on to the plastic part of the connector. By swaying it carefully from side to side, remove the plug.
After the wires are turned off, unscrew the screws that hold the battery in the compartment, usually two or four, depending on the board revision, remove the old module and install the new one, keeping polarity in mind (although it is physically difficult to confuse the connector due to the shape of the key).
| Parameter | Standard G1 battery | Signs of wear and tear |
|---|---|---|
| Capacity | 2,500 mAh | Work less than 40 minutes |
| Tension. | 14.4 B | Not holding the charge. |
| Type | Li-Ion | Bloating of the hull |
| Charge cycles | ~500-800 | Robot doesn't see charging |
Can I use a larger battery?
Once you have the new battery installed, check the contacts for oxidation. If you see white plaque, gently clean it with a dry soft cloth or cotton swab slightly soaked in alcohol. Clean contacts ensure stable current transfer and prevent heating.
Turbine disassembly and suction engine cleaning
If the robot is buzzing louder than usual or making whistling noises, the problem is most likely a fan engine or turbine. In the Xiaomi Vacuum Mop G1, this node is located in the central part and protected by an additional casing.
First, disassemble the side brush by unscrewing the center screw. Then flip the robot over and remove the top panel. It can be mounted on screws under a decorative pad or on latches. Once you remove the cover, you'll see a black cylinder of the engine connected to the duct cochlea.
Cleaning the turbine requires care. Fan blades often wind hair and wool, which create imbalance and noise. Use tweezers to remove large clumps of dirt. You can use compressed air or a soft brush to clean thoroughly.
- 🌪️ Remove the impeller (if the design allows you to unscrew the central screw)
- 🧹 Blow the air ducts from fine dust
- 🔍 Check the engine bearing for backlash
It is important not to wet the engine with water. If wet cleaning is required, use a slightly damp fabric, but make sure that the droplets do not get inside the winding or on electronic control boards.
💡
To lubricate the engine bearings, use only synthetic lubricants that do not conduct current (for example, silicone). Thick graphite or lithium lubricants can collect dust and coke, which will lead to jamming.
After cleaning, assemble the knot in reverse order, make sure that all sealing gums fall into place, otherwise the air channel will be leaky and the suction force will fall.
Chassis maintenance: wheels and sensors
Navigation problems and robot jamming are often linked to contaminating wheels and sensors. The side wheels in the G1 model have a spring mechanism that gets clogged with dirt over time, causing the wheel to stop bouncing and effectively clean the surface.
You don't have to completely disassemble the suspension to clean the wheels, you just have to unscrew the screw that holds the wheel module and remove it from the body, you'll see the spring and the axle inside, and you'll carefully remove the hair from the axle, because that's the main reason for the spell.
The Xiaomi Vacuum Mop G1 uses a gyroscope and optical sensors, wipe the windows of the drop sensors (located around the perimeter of the bottom) and the central pollution sensor (if present in your modification), and mud on them makes the robot think that it is floating in the air or working in the dark.
⚠️ Warning: Do not use aggressive chemicals to wipe the sensors. Alcohol or glass washing agent can damage the optical coating of the lenses, which will lead to improper navigation.
Also check the charging contacts. The metal plates on the bottom must be clean and not oxidized. If the robot does not get up well on the base or interrupts charging, the problem often lies in poor contact due to the layer of oxide or dust.
Regular suspension prevention significantly reduces the risk of damage to expensive motor wheels, it is enough to carry out such a cleaning once every 3-4 months to make the device work as new.
Assembly of the device and verification of functionality
The final step is assembly. It's done in the exact opposite order. The rule is, don't use force. If a part doesn't fit in, you've positioned it wrong or you've forgotten a screw. Check all the connections before you lock the shells.
When installing the bottom panel, make sure all plumes are stacked in their channels and not clamped. Any wire squeezing can cause contact to break when vibrating during operation. Wrap the screws evenly, without skewing, to avoid slits.
Once fully assembled, turn on the device. You should do the first charge under supervision. Check all systems: motion, suction, Wi-Fi connection. If the robot makes bug beeps, check the error codes in the application.
💡
Quality assembly depends on the correct stacking of wires and the absence of excess debris inside the case, one forgotten cog can cause a loud knock when working.
If after disassembly and cleaning the problem has not disappeared, perhaps the malfunction is of a software nature or requires replacing a complex electronic component, which is better to trust professionals.
