Owning smart appliances often requires accurate device identification, especially when it comes to finding compatible filters, brushes, or firmware updates. In the Xiaomi ecosystem, the range of robot vacuum cleaners is huge, and visually distinguishing, for example, the Roborock S5 Max from the Roborock S6 can be extremely difficult, since the design of many devices is unified. A definition error can lead to the purchase of inappropriate consumables or the inability to connect the gadget to the application.
There are several proven ways to get complete information about your device, from a physical inspection of the case to software methods through cloud services. The most reliable way is to check the factory sticker on the bottom cover, where the exact article and Model ID are listed. In this article, we will analyze all possible identification options so you can be sure of what device you are holding.
Often users confuse the marketing name (which is sold in a store) with the technical article required for service, and understanding this difference will help you find information faster in technical documentation and in enthusiast forums. Let's look at the basic methods of determining the model Step-by-step.
Search for factory sticker on the device body
The first and most obvious step is to physically inspect the robot vacuum cleaner itself. Electronics manufacturers are required to place model information on the body of the device in accordance with technical regulations. You need to turn the vacuum cleaner upwards. Be careful: do not drop the device and try not to touch the side brushes so as not to damage their mechanism.
On the bottom panel, you'll find a silver or white barcode sticker, and that's where you'll find all the information you need, look for a field that's labeled Model or Model, and it's usually a code that starts with a prefix, like this, SDJ03XY Or Vacuum-Mop. It's also often nearby. QR-code that can be scanned by a smartphone camera for quick identification.
⚠️ Attention: If the sticker is worn or badly damaged, do not use aggressive chemistry to clean it. This can permanently destroy the information.
Sometimes the sticker may not be in the center, but closer to the side bumper or under the cover of the dust container. In some models, such as the Xiaomi Vacuum-Mop 2 Ultra, the main label is located at the charging station, and the robot itself has only duplicate markings. Carefully examine all available surfaces.
- 🔍 Turn the device over and find the information sticker on the bottom.
- 📄 Look for the "Model" field with alphanumeric code (for example, STYTJ01YM).
- 📸 Take a photo sticker to be able to zoom in on the image and consider fine details.
- 🔋 Check the battery compartment if the device design allows it to be opened.
💡
If the sticker is not readable, try to illuminate it with a flashlight at an angle - embossing or remnants of paint often become more noticeable when sidelighting.
Identification through the Mi Home app
If physical access to the sticker is difficult or unreadable, the most convenient way is to check through a mobile app, and for this, your robot vacuum cleaner must already be paired with a Mi Home (or Xiaomi Home) account, which is good because it shows not only the model but also the firmware version, which is critical in troubleshooting.
Go to the app and select your device card on the home screen, then click on the three dots in the top right corner to enter the settings menu, and in the list that opens, look for the "Device settings" or "General settings" section, and it will show the full model ID, which is often different from the marketing name.
Way to the menu: Home → Device card → (...) → Settings → Device InformationIn this section you will see a technical name, for example, roborock.vacuum.a15. This ID is unique to every modification and regional version, and knowing it, you can pinpoint the compatibility of accessories. MAC-address and serial number that may be required for registration of the warranty.
It is important to note that in some cases, the app may only display a marketing name, especially if the device is added as a “third-party” or through third-party integrations.If you don’t see the full technical code, try changing the region in the app settings, as the same devices may have different identifiers in different geographic areas.
Checking of packaging and documentation
If the device is not unpacked or the box is saved, it is the easiest source of information, manufacturers mark the end of the cardboard box, usually there are two stickers: one with a barcode and a brief description, the other with detailed specifications and a model series.
Notice the side of the lot and the date of production. The model is always duplicated next to it. This is especially true when buying used equipment or when returning to the store, when you need to prove that the package is consistent with the contents. The documentation (user manual) also shows the model on the first page or on the back of the warranty card.
| Type of marking | Location. | Contents | Reliability |
|---|---|---|---|
| Bottom sticker | Bottom panel. | Model, SN, Rated Power | Tall. |
| Mi Home appendix | Settings menu | Full ID, software version | Tall. |
| Packaging | End of the box | Articulum, color, completeness | Medium (if the box is not native) |
| Checks/Order | Online office | Trade name | Low (often inaccurate) |
But be careful: boxes from different batches of the same robot may look identical, but inside may be devices with different Wi-Fi modules (for example, the Chinese version and the Global version), so if you bought the device from hand, it is better to double-check the model through the application, rather than relying solely on the packaging.
☑️ Verification of package conformity
Differences between the Chinese and Global Version
One of the most confusing things for users is the difference between the Chinese (CN) and global (Global) versions of robots, which can be exactly the same on the outside, but technically different in the type of charger plug, voice packet language and, most importantly, the server to connect.
Chinese versions often have specific codes in the title of the article or do not have the prefix "Global". For example, Xiaomi Robot Vacuum S50 (global) and Xiaomi Robot Vacuum S5 (Chinese) are technically different devices in terms of software. Chinese versions may require changing the region in the application to "China" for full operation, which slows down the response of the server.
To see what version you have, look at the charger, and if the plug requires an adapter or is shaped outside your local area, it's a sure sign of the Chinese version, and if there are no CE or EAC marks on the case or on the sticker, that's also true.
⚠️ Warning: Trying to flash global firmware onto a Chinese device (and vice versa) without the appropriate knowledge can lead to the robot being "bricked"; always check the exact model before experimenting with software.

Decoding of articles and model range
Understanding the logic of Xiaomi’s naming convention will help you navigate the device’s specifications instantly. Usually, model code encrypts the year of release or generation. For example, the SDJ series often refers to classic models with LDS navigation, while ZNJ may point to newer modifications with wet cleaning function.
The numbers at the end of the article often point to a generation. The S5, S6, S7 is a Roborock line, where a larger number means the next generation. The Pro, Max, or Plus models have enhanced functionality: a larger water tank, a reinforced turbobrush, or a more capacious battery.
You can use online calculators or model code databases to decrypt the exact code, and by entering the code from a sticker (like STYJ02YM), you get a full commercial name, which is especially useful when you search for parts on AliExpress or eBay, where vendors often use technical articles instead of beautiful names.
- 🔢 The first letters of code point to the platform and manufacturer (Mi Home, Roborock, Dreame).
- 🌍 Prefix "GL" The absence of characters often indicates a global version.
- 📅 The numbers in the middle of the code may correspond to the year of the platform development.
- 🧹 The words "Mop" or "Wet" in the title guarantee the presence of a wet cleaning module.
💡
Knowing the exact article (Model ID) is more important than knowing the marketing name, since it is the article that selects compatible parts and filters.
What to do if the model cannot be determined
In the rare cases where the sticker is missing, the app doesn't see the device, and the box is lost, you can try to identify the robot by its unique design features. Pay attention to the location of the side brush (right or center), the shape of the laser rangefinder (LDS) and the type of wheels.
For example, if the laser sensor is not located in the form of a "tower" at the top, but is built into the body or is not at all (navigating the camera or gyroscope), this narrows the search to specific series.
If nothing works, contact Xiaomi Support or an authorized service center, provide them with a photo of the device from all angles and, if possible, a screenshot from the app from the site. MAC-And the researchers will be able to break through the device through the database and report the exact modification.
