How to know exactly the version of the vacuum cleaner Xiaomi Mi Robot Vacuum Mop

Smart tech owners often face a situation where they need to refine the exact modification of the device to find compatible filters, side brushes or specific repair instructions. Xiaomi’s lineup includes dozens of models that can be visually almost identical, but have radically different internal content. Determining the version of your robot vacuum cleaner is the first step to competent operation and maintenance of the gadget.

There are several reliable ways to get this information, from simply inspecting the bottom panel of the case to deep checking through software. In this article, we will break down all the methods, including reading factory markings, analyzing through the Mi Home app and decrypting code marks, so you can be sure of the compatibility of accessories.

Sometimes users confuse the generation of the device with the software version, which leads to errors when ordering parts. It is important to understand that the hardware version (model) and the software version (firmware) are different entities. The model code starting with STYTJ usually indicates a global version with wet cleaning function, while VSTG - Chinese. Let's break each method down in detail.

Visual inspection of the sticker on the bottom panel

The fastest and most reliable way to know your device's version is to flip it over and find the information sticker, which is usually located on the bottom cover, next to the side brush or the dust collector compartment, and it contains all the information you need, including the serial number, the date of production and, most importantly, the model code.

You don't have to disassemble the device, you just flip it upside down. Pay attention to the Model or Model field. That's the key identifier. For example, the STYJ02YM code indicates the popular Mi Robot Vacuum Mop Essential model, and the VSTG02YM is the version for the Chinese market that requires additional customization to work in other regions.

⚠️ Note: If the sticker is worn or poorly readable, do not try to tear it away completely to see what is underneath.This can damage the case or impair the tightness of the buttons if they are located in this area.

Also on the sticker, the power voltage and battery type are often indicated, which indirectly confirms the version. Global versions are more often labeled 14.4V, whereas some specific modifications may differ. Write down the model code before searching the information on the Internet or the parts store.

Checking with Mi Home or Xiaomi Home

Digital identification is often more convenient, especially if the device is already connected to a Wi-Fi network and configured. Mi Home software collects accurate data about the connected equipment. To find the right information, open the application on your smartphone and go to the home page where all your devices are displayed.

Click on your robot vacuum cleaner icon to enter the control interface. Next, look for the settings menu, which is usually hidden under three dots in the top right corner of the screen or in the gear. In the list that opens, look for the About device or General Settings → About section.

• 📱 This section will indicate the exact model number that matches the sticker on the case.
• 📡 Here the firmware version is displayed, which is important for understanding the relevance of the software.
• 🆔 You will see a unique Device. ID (MAC-address) that is used to link to the server.

The advantage of this method is that the application automatically determines the region of the server to which the device is attached. This is critically important, since the Chinese version (China Version) and the global version (Global Version) can have different server addresses. If the application says that the device is connected to the server "China", then you have a version for the domestic market of China, even if the box says "Global".

Analysis of the box and configuration of the device

If the vacuum cleaner itself is packed or unavailable for rolling over (for example, it is stuck under the sofa), information can be found on the original packaging. Xiaomi box contains detailed stickers on the outside that duplicate information from the bottom panel of the case. This is especially useful when buying used appliances or accessories in the store.

Notice the barcodes and text blocks on the end of the box. It often has the product article. For example, having a Mop in the name on the box guarantees that there is a wet cleaning function and a matching water tank in the kit. Basic versions like Mi Robot Vacuum (without the word Mop) don't have a water tank and a rag mount.

Global versions often have instructions in many languages, including Russian, and a charger plug corresponding to the region of sale (European). Chinese versions can come with an adapter or have a Chinese-standard fork, and the instructions will be entirely in characters.

Differences between Chinese and Global Versions

Understanding the difference between regional versions is critical for users of the Xiaomi ecosystem.The Chinese version (CN Version) is often cheaper when bought on marketplaces, but can cause inconvenience when used outside of China.

The main difference is in servers and voice control: Chinese vacuum cleaners require a connection to the server "China" in the Mi Home application. This can lead to delays in receiving notifications to the phone if you are in another country. Global versions run on local servers (Russia, Europe, USA), providing instant response.

⚠️ Warning: Trying to reflash the Chinese version to the global through official channels is often impossible and can result in a device being blocked ("brick.

In addition, the Chinese versions are tailored to recognize Chinese and English. Russian in the Chinese versions of the Mi Robot Vacuum Mop may be missing or not work correctly, while the global versions have a full-fledged Russification of voice packets and text interface.

Identification by appearance and design

If the sticker is lost and the box is thrown away, you can try to identify the model by design features. Xiaomi engineers often change the location of controls and sensors in different generations. For example, the Mi Robot Vacuum Mop Essential model has a Wi-Fi on button and a power button separated physically, while the Mop 2 Pro buttons can be touch or hidden.

Note the design of the dust collector, which is removed from the top in older models, while in newer series (such as the Mop 2 Lite), the filter can be accessed through the top panel cover without removing the entire container, and the shape of the water tank is also important: in some models it is inserted instead of the dust collector, in others it is attached separately from the bottom.

• 👁️ Location of the laser rangefinder (LDS): Some models have it higher, others have it more compact.
• 🔋 Type of charging: presence of contact areas at the bottom or use of a docking station with contacts on the body.
• 🎨 Top cover color: matte white plastic often indicates newer models, glossy - early versions.

Also worth looking at is the wheels. In cross-country models, the wheels can have a more aggressive tread and a larger diameter, as is the case with the Pro and Max versions. Conventional versions of the Essential often have simpler wheels designed for smooth surfaces.

💡

Take a close-up of the bottom of the vacuum cleaner before buying accessories. Parts vendors can often identify the desired version from a photo of the location of screws and holes.

Frequent errors in model definition

Users often make the mistake of relying only on the name they came up with for the device in the app. When you first set up the Mi Home app, you might want to call the robot "Living Room" or "Kitchen," but that doesn't change its actual hardware model.

Another common mistake is the confusion between the Mi Robot Vacuum (first generation, without wet cleaning) and the Mi Robot Vacuum Mop. Externally, they are very similar, but the lack of a water tank in the kit and a hole for installing it on the dust collector suggests that the mop function in this version is not hardware provided, even if the software wet cleaning menu is sometimes found in beta versions of the software.

You can't trust the product description on aggregator sites blindly. Vendors often mix photos of different versions. The only reliable source is the code on the device itself. If you order a filter, look for compatibility with STYJ... or VSTG..., not the generic name "Xiaomi Vacuum."

⚠️ Note: Use of filters from another model (e.g, HEPA-filter 1S in the Essential model) can lead to a drop in suction power and overheating of the engine due to different aerodynamic drag.
