How to accurately identify the model of the robot vacuum cleaner Xiaomi: from sticker to hidden menus

Xiaomi’s robot vacuum cleaners have become an integral part of smart homes, but sometimes even experienced users have difficulty determining the exact model of their device, which may be necessary to buy parts, update firmware or search for instructions – without knowing the model, you risk buying incompatible accessories or downloading inappropriate software.

Complicating the problem, many models are visually almost identical — for example, the Mi Robot Vacuum-Mop 2 Lite and Mi Robot Vacuum-Mop 2 Pro are only small in detail. In this article, we will examine all the official and hidden ways of determining a model, including those that are not written in the standard instructions, you will learn where to look for factory markings, how to decrypt the serial number and what to do if the sticker is erased.

1. Inspection of the case: where Xiaomi hides the model

The most obvious way is to inspect the vacuum cleaner case, and the manufacturer marks it in a few standard places, but the location depends on the generation of the device.

On most models (e.g. Mi Robot Vacuum) 1S, Mi Robot Vacuum-Mop P, the main data sticker, is located on the bottom cover next to the QR-Look for a white or silver sticker with small print, there's a line of Model or Type. On new devices (2022-2026), the labeling can be engraved with a laser on plastic near the charging connector.

• 🔍 Under the battery cover – on models with removable battery (for example, Mi Robot Vacuum-Mop 2 Ultra).
• 📦 On the box – if the original packaging is retained, the model is indicated on the side sticker or on the bottom.
• 🔋 Next to the reset button – on some versions (e.g. Mi Robot Vacuum) E10) The marking is hidden under a small lid.

⚠️ Note: Stickers on budget models (e.g. Mi Robot Vacuum-Mop Essential) often peel off over time. If the sticker is damaged, try to take a picture of it with a zoom - sometimes you can disassemble the characters.

Serial number: how to decrypt the code of the model

If the marking is erased but the serial number (S/N) is retained, it can be used to identify the model, a serial usually consists of 14-16 characters and contains encrypted information about the device.

The first 3-4 characters often point to a series of models:

• MJX - Mi Robot Vacuum 1 (first generation)
• SDJ or SDM: Mi Robot Vacuum-Mop 2 (Second Series)
• STYJ is the Mi Robot Vacuum-Mop P or Pro.
• LDS – Laser rangefinder models (e.g. Mi Robot Vacuum-Mop 2 LDS).

To accurately determine the model by serial:

1. Turn the vacuum cleaner over and find a line S/N (usually QR-code).
2. Take a picture or write down a number.
3. Enter it into Xiaomi's official checkout service (check warranty section) and the system will show the exact model.

💡

If the serial number starts with 2201 or 2202, your device is released in 2022.The first two digits after the prefix often indicate the year of production (for example, 21 - 2021).

3. Mi Home app: where the model information is hidden

If the vacuum cleaner is connected to the Mi Home app (or Xiaomi Home for newer versions), the model can be recognized through the program interface, which works even for devices without physical markings.

Instructions for Mi Home:

1. Open the app and go to the Devices tab.
2. Find your robot vacuum cleaner on the list and tap it.
3. In the upper right corner, click on ⚙️ Settings (or... → Device information).
4. Scroll down to the About Device block, and there will be a Model or Model Number line.

In newer versions of the app (2023–2026), the path may differ: Device Profile → I in the upper right corner → Technical Data section.

⚠️ Note: In some regions (e.g. European versions of vacuum cleaners), the app may display a code name instead of a trade name (e.g., for example, for the European version of vacuum cleaners, dreame.vac1 Instead of Mi Robot Vacuum-Mop 2 Pro, use the match table below or check the serial number.

4. Hidden menus and voice prompts

Few people know, but Xiaomi’s robot vacuum cleaners have hidden service menus where you can find out the model and the firmware version, which works for most devices based on Mi Home or Dreame (a sub-brand of Xiaomi for vacuum cleaners).

How to open the service menu:

1. Make sure the vacuum cleaner is off (not in cleaning mode).
2. Press the Home (or Dock) button and Power buttons for 5-7 seconds at the same time until you hear the beep.
3. After the beep, release the buttons and the vacuum cleaner will sound the model in English (for example, "Mi Robot Vacuum-Mop Two Pro").

For models with a display (e.g. Mi Robot Vacuum-Mop 2 Ultra):

1. Press and hold the Settings button (⚙️) hull 10 seconds.
2. A menu with a firmware version and model code (e.g. STYJ02YM) will appear on the screen.

5. Definition by external signs

If none of the above methods worked, you can try to identify the model by external features. Xiaomi produces vacuum cleaners with characteristic design elements that help distinguish one series from another.

Key visual differences:

• 🔴 Color of buttons: Mi Robot Vacuum 1S — One physical button (gray). Mi Robot Vacuum-Mop 2 Pro — touch buttons with backlight. Mi Robot Vacuum-Mop 2 Ultra — buttons integrated into the display.
• 📏 Size and shape: 35 cm diameter - budget models (Essential, Lite); 38 cm diameter - flagship series (Pro, Ultra); Square shape - obsolete models (Mi Robot Vacuum 1).
• 🔦 Sensors: One laser rangefinder (rotating tower) - models with LDS (Mi Robot Vacuum-Mop 2 LDS). Infrared sensors only – budget versions (Mi Robot Vacuum-Mop Essential). Dual camera front – new models 2023-2026 (Mi Robot Vacuum-Mop 2 Ultra).

For accurate identification, compare your device to the official images on Xiaomi’s website.

• The shape and color of the dust collector (in Pro versions it is usually black, in Lite - white).
• The presence of a rubber brush (there are only models with the function of wet cleaning).
• The type of side brushes (new models often blue, the old – black).

💡

Models with self-cleaning tank function (e.g. Mi Robot Vacuum-Mop 2 Ultra) have an extra garbage compartment at the docking station. If your station has a large container on the side, that's definitely the Ultra version.

Alternatives: documentation and support

If all methods are exhausted, but the model is still unknown, two reliable options remain:

1. Appeal in support of Xiaomi:

• Write to the official support chat (Robot Vacuum section).
• Attach a photo of the serial number (even if it is partially erased).
• Specify the region of purchase - this will help determine the firmware version and model.

The average response time is 1-2 working days.

Verification of documentation:

• If a check or a warranty card is saved, the model is indicated at the top of the document.
• In the documentation database Xiaomi can enter the serial number and find the user manual, where the model is specified.
• The box from the docking station (if it is saved) usually duplicates the information about the model.

⚠️ Note: When contacting for support, never share the unlock code or Mi Account details. Fraudsters often impersonate Xiaomi employees and request this information to access your devices.

7. Frequent mistakes and how to avoid them

When defining a robot vacuum model, users often make common mistakes that lead to the purchase of inappropriate parts or incorrect settings.

Mistake 1: Misunderstands the trading and code model

• For example, the app displays dreame.vac1 and the user searches for instructions for Mi Robot Vacuum 1 – these are different devices!
• Solution: Use the code and trade name matching table (see Section 2).

Mistake 2: Focusing on color only

• Many models are available in white and black (for example, Mi Robot Vacuum-Mop 2 Lite comes in both shades).
• Solution: Check the serial number or marking on the case.

Mistake 3: Ignoring the regional versions

• The same vacuum cleaner can be sold under different names in China, Europe and the United States, for example, the Mi Robot Vacuum-Mop 2 Pro in China is called the Dreame D9.
• Solution: Check the region of purchase when searching for parts.

💡

If you buy accessories (brushes, filters, wipes) on AliExpress or Amazon, always check compatibility by the exact model code, not by photo. Vendors often use generic images for different versions.
