Many smart tech owners face the need to access the internal components of a device. Often the question is how to open the lid of a robot vacuum cleaner Xiaomi to replace a failed battery, clean clogged sensors or simply conduct deep prevention. Unlike conventional household appliances, the design of these gadgets seems monolithic, which frightens inexperienced users.
Engineers at Xiaomi and sub-brands like Roborock and Viomi are looking for minimalism, hiding all the screws and fasteners under decorative panels. This creates the illusion of indiscriminate, but almost all models are neatly dismantled. The right approach to removing the top panel is the key to extending the life of your robot vacuum cleaner.
Before you start to physically affect the body, you need to clearly define the model of your device. The design of the lid on the Vacuum Mop series and the classic Vacuum can be significantly different. Mistakes can lead to breakage of plastic latches, which then have to be restored.
Workplace preparation and necessary tools
Any electronics disassembly requires an organized space. You'll need a clean, well-lit desk so that small parts like screws or springs don't get lost in the carpet pile. Pay special attention to the lack of static electricity, which can damage the sensitive electronics inside.
To do this successfully, you need a minimal set of tools. A standard set of screwdrivers should include cross bits of size PH0 and PH1, as well as a flat screwdriver for tweaking panels. In some models, there may be screws with an asterisk, so having a T5 or T6 bit will not be superfluous.
- 🔧 A set of precision screwdrivers with magnetic tips for holding screws.
- 🛠️ Plastic blade (spooger) or mediator for safe opening of latches.
- 🧤 Antistatic gloves to protect the board from static discharges.
- 📱 Smartphone with camera for photographing the stages of disassembly.
Using metal tools to tamper with plastic is strongly discouraged, as it is almost guaranteed to leave scratches or chips on a glossy surface.A plastic spooger or even an old bank card will be much better for delicate work.
💡
Before starting the disassembly, be sure to take a picture of the location of all the screws and plumes, this will help to assemble the device back without unnecessary details.
Determination of type of attachment according to model
There are two main ways to attach the top cover to Mijia ecosystem devices: the first option involves hidden screws under rubber plugs or stickers; the second, more common in new models, uses a system of internal latches around the perimeter of the housing.
Visual inspection of the flashlight device will help identify the mounting locations. Often the screws are hidden under the brand logo or decorative ring around a laser rangefinder (LDS). In models without a laser turret, the fasteners can be hidden under control buttons or in bumper recesses.
It's important to understand the difference between a removable dust container and a non-removable top panel. If you just want to shake out the garbage, you don't have to open the case, you just need to remove the dust collector. Access to internal electronics is only required for major repairs.
Step-by-step instructions for removing the upper panel
The dismantling process should begin with removing all visible screws. Turn the robot vacuum cleaner bottom up and make sure that the side brush is removed so that it does not interfere with access to the screws in the bottom of the body, if they are provided there by the design of a particular modification.
Once all screws are unscrewed, the top cover must be carefully detached, so that the plastic blade is inserted into the junction between the top and bottom of the body, and the movements must be forward, not lever, so that the plastic does not break.
☑️ Algorithm for cap removal
Walk the shoulder blade around the perimeter of the device, sequentially releasing the latches. A characteristic click will signal a successful disconnect. Do not try to sharply pull the lid up if it does not respond, so you missed the screw or did not snap the lock.
When the lid is lifted a few millimeters, you can't pull it completely, and you have plumes inside that connect the control buttons, the indicators, or the laser module to the main board, and if you move abruptly, you'll break the contacts and have expensive repairs.
Working with internal components and plumes
And when you lift the lid carefully, you'll see the inside of the robot, and you'll see the battery pack, the main motor, the control board, the sensors, all of these connections are made with connectors that require careful handling.
Trains are often fixed with special clips, and to disconnect them, you need to carefully bend the lock (if any) and pull the tongue of the plume, not the wire itself. Tweezers are permissible, but only if its sponges do not damage the thin tracks.
⚠️ Attention: Never pull the wires themselves. They're very thin and easily torn at the base of the connector. Always only take a thickened contact tongue.
If your goal was to replace the battery, you can now unscrew the battery mount and disconnect the power connector. When installing a new battery, make sure that the polarity is met, although the design of Xiaomi connectors usually eliminates erroneous connection.

Table of compatibility of opening methods for popular models
Different models require an individual approach. Below is a summary table that will help you navigate the nuances of disassembling specific devices in the Roborock and Xiaomi line.
| Model of the device | Location of screws | Latch type | Features |
|---|---|---|---|
| Xiaomi Vacuum 1 / 1S | Under the top cover, 4 pcs. | Tight, perimeter. | You need to remove the dust collector cover first. |
| Roborock S5 / S5 Max | Under the rubber cap on top | Medium-severity | Careful with the button plume |
| Xiaomi Vacuum Mop | No external screws. | Hidden, very tight. | Heating of the body with a hairdryer is required |
| Roborock S6 / S7 | Inside the dust collector compartment | Fragile. | Lots of plumes, you need to be careful. |
This table is for reference, as the manufacturer can make design changes in different revisions. Always rely on a visual inspection of a particular instance.
💡
The main difficulty of disassembling modern models is the absence of visible screws and the use of a large number of hidden latches around the perimeter.
Possible problems and ways to solve them
During disassembly, users often find the lid not opening even after all the screws have been unscrewed, which may mean that one of the latches is sitting too tightly or the plastic case has deformed with time and temperature.
In these cases, you can try to warm the body slightly with a hair dryer, warm air makes the plastic more elastic, which makes it easier to snap the mounts, but do not overdo it: the temperature should not exceed 60-70 degrees, so as not to melt the glue or damage the internal components.
⚠️ Warning: If you hear a crunch of plastic when you try to open the lid, stop immediately.You're probably pressing in the wrong place or forgetting to unscrew the hidden screw.
Another common problem is sticking the power button or sensors due to moisture. If after opening the lid you find traces of corrosion, gently clean the board with alcohol and a soft brush, allowing it to dry completely before assembly.
Assembly of the device and check of performance
The assembly is done in reverse order. First of all, all the plumes and connectors are connected. Make sure that each connector is standing before the characteristic click and is fixed with a clamp. Then carefully stow the wires so that they do not fall under moving parts or are not clamped by the housing.
When you install the top cover, first snap one corner, then the opposite, and only then walk around the perimeter, pressing your fingers until you click.Do not use a hammer or excessive force - if done correctly, the lid will fall into place easily.
The final step is to screw the screws in, and you can twist them cross-wise, without putting too much effort into the plastic racks, and then you can turn the screws on and check all the functions, like brush rotation, wheel movement, and Wi-Fi connectivity.
