Smart tech owners often face confusion about names when trying to find compatible consumables or instructions. The question of which generation of Xiaomi Vacuum Mop vacuum cleaner is key to getting the right filters, brushes and wet wipes. The Chinese giant’s line of cleaning robots has evolved rapidly, and visual differences between models can be minimal, although the interiors vary dramatically.
Understanding device generation is not only essential for buying accessories, but also for working properly in the Mi Home app. Different generations have different communication protocols, different mapping algorithms, and different navigation systems. If you go wrong with the version, the smart home may simply not see your gadget or offer incorrect use cases.
In this article, we will take a closer look at the evolution of models so that you can accurately identify your assistant, and we will touch on technical nuances that are hidden from the eyes of the average user, but are critical for long-term use of the equipment.
Determining the model is the first step to properly maintaining your device. Without accurate knowledge of the version, it is difficult to find original components, and using incompatible analogs can lead to rapid wear and tear of the engine.
The evolution of the line of robot vacuum cleaners Xiaomi
The company's robotic cleaners have been around for several years, and each generation has revolutionized their development: early models, such as the Xiaomi Mi Robot Vacuum Cleaner (the first generation), relied solely on dry cleaning and laser navigation, and became the benchmark for reliability but lacked the wet wipe function that later became the de facto standard.
With the second generation, known as the Xiaomi Mi Robot Vacuum Mop, the water tank was installed, allowing the combination of dust suction with wet cleaning, albeit in basic mode, and it was here that many users first wondered what generation their device was, as the design remained recognizable and the functionality expanded.
⚠️ Note: Visually, the first and second generation models can be almost identical. The key difference is often the presence of a water tank slot under the top cover.
Third generation and specialty series like Xiaomi Vacuum Mop 2 or Pro have seen significant improvements in navigation, with carpet recognition, more powerful suction and, importantly, improved obstacle-avoidance algorithms. Generational differences now dictate not only the presence of the tank, but also the type of lidar, engine power and even the height of the hull.
Key differences between Gen 1, Gen 2 and Pro generations
To determine exactly what class your device belongs to, you need to pay attention to a number of technical characteristics: the first generation (Gen 1) is characterized by the white color of the case, the lack of floor washing function as standard, and the use of a black and white card in the application. The suction power here was 1800 Pa, which was a great indicator for its time.
The second generation models (Gen 2), often labeled Vacuum Mop, retained the dimensions of the predecessor, but got a pink accent on the top cover (in some versions) or a modified grille design. The main innovation was the support for a water tank 2-in-1. suction power increased to 2100 Pa, and the application has the ability to adjust the water supply.
The Pro series and newer versions (Gen 3 and above) offer a black or dark gray body color, increased power to 3,000 Pa and quieter operation. These models often use an improved HEPA filtration system and more capacious batteries.
- 🤖 Navigation: Gen 1 uses basic lidar, Gen 2 and Pro have improved map-building and zoning algorithms.
- 💧 Wet cleaning: Available only in Gen 2 and later, Gen 1 requires you to buy the module separately (not always compatible).
- 🔋 Autonomy: New generations work longer thanks to better power consumption and higher capacity batteries.
💡
Pay attention to the bottom of the robot: having contacts to connect the water tank is a sure sign of wet cleaning support (Gen 2+).
How to visually determine the model of the device
The fastest way to know what generation your Xiaomi Vacuum Mop is is to look at the look. Turn the device over and look at the main brush. In the first models, it had a specific design with yellow bristles on the sides. In the newer versions, the brush became fully rubber or combined, which reduces hair wounding.
Also, look at the sensors. On the top panel, where the laser rangefinder (LIDAR) is located, the shape of the IR sensor window may differ from generation to generation. The Pro often has a more massive black lidar turret, while older versions have a white and less visible color. The top lid color is the most obvious marker: classic white for older versions, graphite or black for newer versions.
Be sure to check the markings on the bottom cover. It always shows the exact model number, for example, SKV4036GL or STYJ02YM. These codes are a way of one hundred percent identification if visual features seem doubtful to you.

|---|---|---|---|

Software Identification through the Mi Home app
If the visual inspection didn't give a definitive answer, go to the software. The Mi Home app (or Xiaomi Home) displays the exact name of the connected device. Go to the robot card, click on the three dots in the upper right corner and select Settings. The Device or Information section will show the full model name.
And the control interface can also suggest a version. In the old firmware for Gen 1, the map interface was simpler, without the ability to create virtual walls in some regions. 3D-So if you see a map, you set up the cleaning sequence, and you pick the type of coating for each zone, if you see a "Carpet Type Choice" or "Washing Intensity" feature, it's not exactly the first generation.
⚠️ Warning: Make sure the region in the Mi Home app matches the region of the device.Chinese versions (CN) Global (Global) may display information differently, but the model number will remain unchanged.
Also worth checking is the firmware version. Go to the robot's settings and find the update point. Update history often includes information about which model the update is intended for. If the system offers to update the software for Mop P, then your device belongs to the corresponding line.

Compatibility of consumables and accessories
The question of consumable compatibility depends on what generation your vacuum cleaner is. HEPA filters, side brushes and main brush often have different attachment geometries. For example, filters for Gen 1 are rounded with a mesh, while in newer models they can be rectangular or have a different fixation system.
The water tank is another critical element: the Xiaomi Vacuum Mop (Gen 2) tank will not physically fit into the Xiaomi Mi Robot Vacuum (Gen 1) body without modifications, as the location of contacts and the shape of the niche differs. Moreover, the electronics of older models may not recognize the presence of the tank, and the wash function simply does not activate.
When buying spare parts, always look for the model number, not just the name "Xiaomi." The market is full of universal counterparts that are suitable for several generations at once, but for original components, accuracy is important. Using an inappropriate filter can disrupt the tightness of the system and lead to dust entering the engine.
- 🧹 Main brush: Changes once in a while 6-12 months, depending on generation and gender type.
- 💨 HEPA-filter: Requires replacement every time 2-4 The form is critical for a particular model.
- 🧽 Microfiber rag: Fastening may be different (Velcro, clamps), check compatibility.

Frequent problems and their solution depending on the version
Different generations of robot vacuum cleaners are prone to specific “childhood diseases.” First-generation devices often suffered from rapid battery failure and problems connecting to 5GHz Wi-Fi (they only support 2.4GHz). Gen 1 users also often complained of getting stuck in dark corners due to less advanced drop sensors.
Second-generation models and Vacuum Mop are more likely to face wet cleaning problems, pump pore clogging, uneven water supply, or water-level sensor errors are typical scenarios, and these versions sometimes feature software bugs where the robot forgets the map of the room after the upgrade.
Pro and newer series have difficulty calibrating lidar after impacts. If the robot falls from the doorstep, the laser unit can get lost and the map becomes a curve, in which cases mechanical adjustment or reset navigation settings through an engineering menu (not available in all regions) are required.
💡
Knowing the exact version of the device allows you to quickly find a solution in official manuals and forums, since troubleshooting for Gen 1 and Gen 3 is radically different.
Recommendations for updating and maintenance
No matter what generation your Xiaomi Vacuum Mop is, regular maintenance will extend its life. Clean Cliff sensors with dry soft cloth. The accumulation of dust on them makes the robot think there's a cliff ahead, and it starts to tread back or spin in place. This is true for all versions without exception.
Watch the condition of the wheels. The wool and hair are wound on the axle, which puts additional strain on the wheel motors. Remove the side brush and wheel periodically (if the design allows) for deep cleaning. In new models, the wheels have a more complex suspension, and cleanliness there is especially important for cross-country carpeting.
Update the software. Xiaomi regularly releases patches that improve obstacle avoidance algorithms and connection stability. Even if the robot works well, installing the latest firmware can correct hidden logic errors accumulated over the course of operation.
Comparative table of generational characteristics
For convenience, we will summarize all the data in a final table that will help you to finally decide on the version of your device. Pay attention to the weight and dimensions - they can also serve as an indirect sign, as new models are often more compact or, conversely, more massive due to the increased tank.
