How to accurately determine the model of the vacuum cleaner Xiaomi: from marking to mobile application

Have you bought a used Xiaomi robot vacuum cleaner without a box, lost your documents or just wanted to clarify the exact modification of your device? Model identification is a critical step before buying parts, firmware or setting up through the Mi Home. A single character error in the name can lead to incompatibility of accessories, malfunctions or even failure of equipment.

In this article, we will analyze all official and alternative ways to identify Xiaomi vacuum cleaners, including hidden markings, features of mobile applications and nuances for devices under the Dreame, Viomi and Mijia brands. Particular attention will be paid to models that are seemingly indistinguishable (for example, Mi Robot Vacuum-Mop 2 Lite vs Dreame D9), but have different firmware and components.

1.Where to look for factory markings on the vacuum cleaner body

The most reliable way is to find the serial number and model on the manufacturer's sticker, which Xiaomi has in three standard places, but access to them may require disassembly:

• 🔍 Under the battery compartment cover, unscrew the 4 screws on the bottom panel (usually under a rubber leg or next to the brushes.
• 📦 At the bottom of the device - models Mi Robot 1S/2S viomi V2/V3 The marking can be hidden under the central brush (you will have to remove it).
• 🔌 Next to the charging connector – in some versions (for example, Dreame) F9) sticker hidden under rubber cap.

On the factory sticker, look for the lines Model: [name], S/N: [serial number] or TYPE: [model code]. If the model is listed as "MJSTFJS01FM" it is Xiaomi's internal code that you need to decrypt through the manufacturer's database (see section 4).

💡

If the sticker is erased, try to light it up with a flashlight at an angle - UV ink is often used to duplicate the serial number.

2. How to distinguish Xiaomi from Dreame, Viomi and Mijia by appearance

The Dreame, Viomi and Mijia brands belong to the Xiaomi ecosystem, but their vacuum cleaners have key differences in design and function.

⚠️ Attention: Dreame Bot models Z10 Pro and Xiaomi Mi Robot Vacuum-Mop 2 Pro are identical in appearance, but use different docking stations and firmware!

3. Model definition through mobile applications

If the vacuum cleaner is connected to Wi-Fi, you can find out the model through official applications.

For vacuum cleaners Xiaomi Mi and Viomi (application Mi Home):

1. Open Mi Home and go to the Devices tab.
2. Choose your vacuum cleaner → Settings (⚙️) → About the device.
3. In the device information block, the Model string will be used (e.g. roborock.vacuum.a10 for Mi Robot Vacuum-Mop 2 Pro).

For Dreame vacuum cleaners (Dreamehome app):

1. In the main menu of the application, tap on the vacuum cleaner icon.
2. Go to Settings. → About the programme.
3. Look for the Model Number field (e.g. dreame.vacuum.p2046 for Dreame D9).

⚠️ Note: If the Mi Home displays the model as zhimi.vacuum.v1 — This is Xiaomi Mi Robot Vacuum 1 (first generation) and does not support modern firmware and may conflict with newer versions of the app.

Open Mi Home/Dreamehome

Find a vacuum cleaner in the list of devices

Go to "Settings" → "About the device"

Copy the line "Model" or "Model Number"

Check with the database on the official website-->

4. decoding of internal model codes (MJSTFJS01FM, etc.)

Xiaomi uses encrypted model codes on stickers (for example, MJSTFJS01FM or LDSXXD05RR). To translate them into the usual name, use this table:

If your code is not in the table:

1. Go to the Xiaomi authentication site.
2. Enter the serial number (S/N) from the sticker.
3. The system will show the official name of the model and the date of production.

5. firmware analysis to accurately define the model

Each model of Xiaomi vacuum cleaner has a unique firmware identifier that can be extracted through Mi Home or Dreamehome.This method works even if the sticker is missing:

1. In the application, go to the vacuum cleaner settings → About the device → The firmware version.
2. Copy the full version number (for example, 3.5.9_0042).
3. The first digits before the emphasis (3.5.9) are the software version, and after (0042) the model code.

Check the code against this table:

• 0042 — Xiaomi Mi Robot Vacuum-Mop 2 Pro
• 0038 — Dreame D9
• 0021 — Viomi V3
• 0015 — Xiaomi Mi Robot Vacuum 1S

⚠️ Note: If the firmware version starts with 1.x.x, your device is outdated and may not support modern features (e.g. zoning or voice assistant). ADB (see section 7).

6. Visual differences of popular models (photo comparison)

If you don’t have access to a sticker or app, focus on the design features:

• 📸 Laser rangefinder (LDS): Round module — Xiaomi Mi Robot or Viomi. Square module — Dreame D9/F9.
• 🔋 Power button: Mechanical button - old models (Mi Robot 1). Touch button - new models (Mi Robot Vacuum-Mop 2 and higher).
• 🧹 Brushes: One side brush is a budget model (Mi Robot Vacuum-Mop 2 Lite). D9 Max, Viomi V3 Max).

💡

Take a picture of the top panel of the vacuum cleaner and compare it to the directory at [mi.com](https://www.mi.com/global). Pay attention to the location of the buttons, indicators and laser modules - these are the most reliable visual markers.

7. Alternative methods: via Wi-Fi, MAC-address ADB

For advanced users, there are additional identification methods:

Through MAC-address:

MAC-vacuum address (e.g, 78:11:DC:XX:XX:XX) find:

• In the router settings in the list of connected devices.
• In Mi Home → Vacuum Settings → Network Information.

First 6 characters MAC-address (78:11:DC) They point to the manufacturer. It's usually Xiaomi:

78:11:DC

48:5F:99

64:09:80

Through ADB (for Android):

If the vacuum cleaner is connected to the same network as your smartphone, you can send a command:

adb shell dumpsys bluetooth_manager

In the output, look for the line name=miio:device:..., where the colon will be the model (for example, roborock.vacuum.a10).

💡

MAC-address ADB-commands are the only ways to determine a model if the vacuum cleaner doesn't turn on or connect to an application.
