How to accurately determine the model of the vacuum cleaner Xiaomi

Owning a Xiaomi smart vacuum cleaner or the Mijia ecosystem is always a convenience, but sometimes the owner is asked what model I have? This may be necessary to find compatible filters, order a side brush or try to connect the device to the Mi Home app. Visually, many robot vacuum cleaners look almost identical, having a round body and a similar arrangement of sensors, which often confuses users.

Understanding the exact model name is critical, as technical support and instructions are always tied to a specific item. A series definition error can result in the purchase of inappropriate supplies or the inability to update firmware. In this article, we will discuss all the available ways to help you identify your device accurately using both physical tags on the case and software methods.

Don’t rely on the name you saw when you bought in-store, as sellers often use marketing names that are different from the actual factory indices. For example, the popular Xiaomi Vacuum Mop can hide different modifications with different characteristics.

Search for a sticker on the bottom panel of the device

The most reliable and quickest way to know the exact model is to physically inspect the bottom of the robot vacuum body. Xiaomi manufacturers and their ecosystem partners (such as Roborock, Dreame, Viomi) place the information sticker in this place so that it does not erase during operation. You will need to flip the device, pre-switch it off or pause it.

The Model or Model field is usually indicated by an alphanumeric code, such as STYTJ01YM or SDJQR02RR. This code is a unique identifier, often accompanied by Rated Power and Rated Voltage, which also helps confirm the origin of the device for a specific region.

⚠️ Warning: Never try to remove a sticker with information if it is partially erased. Better take a carefully photographed text residues in good light and use a magnifying glass on your smartphone to read. Damage to this area can complicate warranty service.

Sometimes the sticker can be partially hidden under a removable side brush or wheel, so carefully inspect the entire surface of the bottom.If the label is heavily contaminated, it can be gently wiped with dry cloth, avoiding the use of aggressive chemicals that can finally destroy (print).

Identification through the Mi Home app

If physical access to the bottom panel is difficult or the device is already installed in a hard-to-reach place, the easiest way to know the model is through the software. The Mi Home app (or Xiaomi Home) stores full information about the connected devices.

Go to the app and select your robot vacuum card. The top right corner of the screen usually has a three-dot button or settings icon.... Clicking on it will take you to the device management menu. Scroll down to the very end of the About or Device section.

This section will show you the full path to the device, including its model, and often shows not only the factory code, but also an understandable name, such as the "Xiaomi Robot Vacuum Mop 2 Pro+." It also provides a firmware version, which is useful when looking for solutions to specific software bugs.

It is important to note that in different regional versions of the application (China, Europe, Russia), the display of the name may differ slightly, but the technical code of the model will remain unchanged. If you use third-party integrations such as Home Assistant or Yandex.Smart Home, the model is also often prescribed in the properties of the device, but in a format that requires decryption.

Decoding of codes and serial numbers

Factory codes for Xiaomi models and sub-brands may look like a meaningless set of letters and numbers, but they carry a certain structure. Understanding this structure helps determine not only the model, but also the year of release or the region of destination. For example, codes starting with STY... often refer to vacuum cleaners manufactured for the global market or China.

The serial number (Serial Number or S/N) also contains useful information, although decrypting it requires reference to the manufacturer's databases. However, the first few characters of the serial number often indicate the manufacturer and the assembly date, which is especially important when ordering parts, since there may be different engine or battery revisions within the same model.

Below is a table of matching popular marketing titles and their technical codes to help you navigate:

Using this table, you can easily match the code from a sticker with a known name. Note that the manufacturer (OEM) may be different: the same Xiaomi brand produces vacuum cleaners at Dreame, ZhiMi, Viomi or Roborock plants, and each has its own design features.

Definition of model by appearance and characteristics

If the sticker is missing and the app is not installed, you can try to identify the device by its unique appearance. The design of the Mijia line has evolved, and each series has its own characteristics. For example, early models had a protruding tower laser rangefinder (LDS) in the center, while new ones can use LiDAR technology in a flatter case.

Note the location of the control buttons. Some models (such as the Xiaomi Vacuum 1S) have only one on button, others (Xiaomi Vacuum Mop 2) have three separate buttons for different modes. Also important is the design of the water container: it can be built-in, combined with a dust collector or removable electronic.

Key visual differences to look out for:

• 🔴 Body height: Models without lidar (gyroscope navigation) are usually thinner (about the size of the gyroscope) 8-9 cm) to climb under low furniture.
• 🔵 Type of sensors: The presence or absence of a rotating laser unit on the top cover is the main divider of device classes.
• 🟢 Color and texture: Classic models are white and glossy, the Pro series often have matte finishes or black elements.

Also worth checking is the complete set: the presence of a dock with automatic dust discharge or automatic washing of a rag immediately narrows the search to the flagship models of recent years of release.

Check through QR-packet-code

On the box from the device, and sometimes on the vacuum cleaner itself (usually under the cover of the dust collector or next to the reset button), located QR-Scanning this code with a smartphone often gives a direct link to the device page in the app or to the support site, indicating the exact model.

Use a standard smartphone camera or the Mi Home app (button"+" in the corner -> "Scan"). If the code leads to the add-on page, the model name will be listed in the header of the connection window. This is the fastest way for new devices that have not yet been activated.

If the scan is QR-If the code is not working (e.g., the code is corrupted or leads to a Chinese domain that is not opening), try to find an alphanumeric string next to the code. QR-Type this code into the Google search box, and you are likely to be taken to a forum or store describing your model.

What to do if the model is not defined

In rare cases, none of the methods provide a clear answer, and this can happen with devices designed for the domestic Chinese market (CN Version) that have been imported informally, in which case the names in the app may be in Chinese and the codes do not break through the global database.

In this situation, technical specification analysis will help. Go to the Wi-Fi router settings. Find the device in the list of connected customers. The device name (Hostname) often contains a hint. For example, the name vacuum cleaner may be too generic, but rockrobo.vacuum.v12 already indicates a specific platform.

Try to do the following to clarify:

• 🔍 Check the charger: the power supply also often duplicates the model of the compatible device.
• 📦 Find the original box: even if it is used for storage, there is usually a sticker on the end with a barcode and name.
• 📸 Take a photo of the device and use a search by image in Google or Yandex, adding the word "Xiaomi".

⚠️ Warning: Do not attempt to disassemble the vacuum cleaner case to find a model on the control board if the device is warranty-free, this will result in loss of warranty obligations and may damage fragile sensor plumes.

Why it is important to know the exact model before buying parts

Buying filters, brushes and rags is a regular necessity for robot vacuum cleaners. The market is saturated with compatible accessories, but they are not always universal. Even within the same Xiaomi line, dust collectors can change sizes or filter attachment type (HEPA vs. cyclone).

Using an inappropriate filter can cause the suction power to fall and the engine to overheat, as airflow resistance will be calculated incorrectly. Wet cleaning rags also have different textures and attachment systems (Velcros, magnets, clamps), and an error here will cause water to be supplied unevenly.

Always check the parts article against the code of your model. If you buy original consumables, they will be labeled according to your model. If you choose counterparts from third parties, the product description must contain a list of compatible models, where your code should appear.
