Why it’s important to know the generation of your Xiaomi Vacuum Mop – and how to do it without making mistakes
Did you buy a used Xiaomi robot vacuum cleaner, lose the box, or just want to make sure the seller didn't cheat on the model? Xiaomi Vacuum Mop generation definition is critical for matching accessories, firmware, and even selecting cleaning modes. 2-generation (1T/2C) not support function AI-The maps available in Mi Robot Vacuum-Mop 2 Pro, and Ultra models require special detergents.
The problem is that Xiaomi often releases updated versions under the same name, adding letter indexes (1S, 2 Lite, Pro+). They can only be different in small details, such as the color of the buttons, the location of the sensors or the shape of the bumper. We have collected 5 proven ways to recognize the generation of your vacuum cleaner, even if you only have the gadget itself without documents.
Important: some methods (for example, checking through Mi Home) work only when you connect to your Xiaomi account. If you bought a vacuum cleaner with your hands, first perform a factory reset, otherwise you risk getting the data of the previous owner.
Method 1: Searching for a generation by serial number (SN) — most reliable
Serial number (SN) — This is your robot vacuum cleaner's passport, and it contains encrypted information about the model, the release date, even the country of manufacture:
- 📦 Box – usually on a barcode sticker (look for a line) S/N or Serial Number).
- 🤖 Bottom of the vacuum cleaner - flip the device and inspect the sticker next to QR-code.
- 📱 In the Mi Home app - path: Device profile → Settings (⚙️) → Device information.
Xiaomi Vacuum Mop serial number has a format: XXXXXYYMMDDZZZZZ, where:
- YYYY — year of issue (for example, 2022),
- MM — month,
- DD is a day.
But for generation definition, the first 5 characters (model code) are more important.
| Model code (SN) | Full name | Generation. | Year of release |
|---|---|---|---|
| VACMOP | Mi Robot Vacuum-Mop | 1st (basic) | 2019 |
| VACMOP1S | Mi Robot Vacuum-Mop 1S | 1st (updated) | 2020 |
| VACMOP2 | Mi Robot Vacuum-Mop 2 | 2nd (basic) | 2021 |
| VACMOP2P | Mi Robot Vacuum-Mop 2 Pro | 2nd (Pro version) | 2021–2022 |
| VACMOP2U | Mi Robot Vacuum-Mop 2 Ultra | 2nd (flagship) | 2022 |
⚠️ Note: If the serial number contains the letters L or T (for example, VACMOP2LT) — These are modifications of Lite or Turbo, which belong to the same generation, but with stripped down functions (for example, without a laser rangefinder).
Method 2: Visual differences of generations - what to look for on the case
If the serial number is erased or you can't find it, check the vacuum cleaner for key visual markers. The manufacturer changes the design with each generation - sometimes radically, sometimes barely noticeable.
Compare your device with this table:
| Sign. | 1st generation | 2nd generation | Pro/Ultra |
|---|---|---|---|
| Colour of the button | Grey or black. | White with lights | Touch (no button) |
| Bumper shape | Rectangular, protruding | Rounded, level with the body. | Rubber with sensors |
| Location of IR sensors | On the sides (2 pcs) | In a circle (4-6 units) | Hidden under the bumper |
| Laser rangefinder (LDS) | Absent. | There (protruding "tower") | Drown in the enclosure |
🔍 Hint: Ultra models on top have a camera for 3D-mapping (a small round window next to the tank lid) instead of pro-versions, additional humidity sensors.
⚠️ Note: Some sellers stick stickers from newer models on old models (for example, 1S Always double-check the serial number, visual differences can be forged!

Method 3: Checking with the Mi Home app is a fast, but not always accurate method
If the vacuum cleaner is already connected to the Mi Home, open its profile and pay attention to:
- The name of the model in the title (for example, Mi Robot Vacuum-Mop 2 Pro).
- Firmware version in the Settings section → Device information.
- Available features (for example, Zone cleaning is only available in the 2nd generation and later).
📌 Step instructions:
☑️ Checking a generation through Mi Home
⚠️ Note: In some regions (e.g. Europe), Xiaomi is releasing modifications with different names. For example, Mi Robot Vacuum-Mop 2 in China may be sold as Mi Robot Vacuum-Mop 2 Global abroad - but this is the same 2nd generation!
💡 Useful tip: If Mi Home displays an incorrect model, try it:
- Update the application to the latest version.
- Reconnect the vacuum cleaner to the account (remove and add again).
- Changing your account region to China (in your profile settings) sometimes reveals hidden features.
Method 4: Online Serial Number Check on Xiaomi
The official service Xiaomi allows you to verify the authenticity of the device and find out its exact model SN or IMEI (If there is, for that:
- Go to the authentication page.
- Enter the serial number (without spaces).
- Enter the code from the picture.
- Press Verify.
The system will show:
- 📋 Model of device (e.g, MJCTD01XM — Mi Robot Vacuum-Mop 2 Lite).
- 📅 Activation Date (will help check if vacuum cleaner is “dropped” after theft).
- 🌍 Sales area (important for firmware compatibility).
⚠️ Note: If the site is in error SN, It could mean:
- Serial number entered incorrectly (check the register of letters!).
- The device is a fake (clone).
- The vacuum cleaner is manufactured for the domestic market of China and is not intended for export.
💡
If the Xiaomi site check doesn’t work, try entering the serial number in the Google search box in the format: Xiaomi VACMOP2P SN:your number. Often on forums (e.g, 4PDA) Users are sharing databases with decryption SN different parties.
Method 5: Analysis of functions and technical characteristics
Each generation of Xiaomi Vacuum Mop has unique hardware and software chips. Compare the capabilities of your vacuum cleaner with this table:
| Function/characteristics | 1st generation | 2nd generation | Pro/Ultra |
|---|---|---|---|
| Type of navigation | Gyroscope + IR sensors | LDS (laser) | LDS + 3D-camera |
| Max. suction force (Pa) | 2000–2500 | 2700–3000 | 4000+ |
| Volume of dust collector (ml) | 450–550 | 550–600 | 600+ (self-empty) |
| Support for zone cleaning | ❌ No. | ✅ Yes (via Mi Home) | ✅ Yes. + multi-room |
| Automatic lifting of mops | ❌ No. | ✅ Yes, some models) | ✅ Yes. + pressure-regulation |
🔧 How to check:
- 🔍 Suction Force: Turn on Max mode and listen - Ultra hears its characteristic high-frequency hum.
- 🗺️ Type of navigation: If the vacuum cleaner "draws" a map of the room in real time - this is the case LDS (2nd generation. If you drive randomly, gyroscope (1st generation).
- 💧 Functions of the mop: B Pro/Ultra You can adjust the intensity of the wash (the app has a Water Level slider).
⚠️ Note: Some features may be blocked by firmware for certain regions, such as the Mi Robot Vacuum-Mop 2 for China, which supports voice control via XiaoAI, but the global version does not.
💡
If your vacuum cleaner doesn’t pull the specifications of the claimed generation (for example, called 2 Pro, but no laser rangefinder), it’s most likely a fake or “relabeled” model.
What if we can’t define a generation?
If none of these methods worked, try:
- Contact Xiaomi Support: Send photos of the vacuum cleaner (especially stickers with the SN) Boxes (if any) to support mail@mi.com Or through a chat at Mi Home.
- Contact the service center: Official Xiaomi partners have databases with serial numbers and can accurately identify the model.
- Request data from previous owner: If you bought used, ask for a screenshot from his Mi Home account with information about the device.
💡 Tip: If you plan to buy accessories (such as mop wipes or mop wipes) HEPA-filters, check with the seller compatibility with the specific model code (for example, STYJ02YM Mi Robot Vacuum-Mop 2 Pro will save you time and money.
⚠️ Warning: Do not use parts from other generations! 1S It's not going to work for 2 Ultra, different tanks (2000 mAh vs 3200 mAh) and connectors, and it could cause a fire or a vacuum cleaner to fail.
