How to find out the model of the robot vacuum cleaner Xiaomi in the Mi Home app

Smart tech owners often face a situation where they need to accurately identify a device, but external labels have been erased or lost. This is especially true for the Xiaomi ecosystem, as the manufacturer produces dozens of modifications of robot vacuum cleaners under different sub-brands, and knowing the exact model is necessary for selecting consumables, finding firmware or contacting support.

The most reliable and quickest way to get this information is to use official software. The Mi Home app stores all the data about connected gadgets, hiding it in the nested menus. In this article, we will discuss in detail where to look for cherished numbers and letters, and explain how marketing name differs from technical.

Often users confuse the serial number of a device with its model. These are different identifiers, each of which plays a different role. The serial number is unique for each particular instance, while the model determines the line and characteristics of the device. We will learn to find both parameters so that you can correctly navigate the smart home menu.

Mi Home application interface and home page

The first step to get information about your device is to log into the main control menu. After you run the Mi Home app (or Xiaomi Home), the home screen displays a grid or list of all the connected gadgets, and that's where the primary entry point for a particular robot vacuum cleaner settings is located.

You don't have to look for complicated hidden menus on the start screen. You just have to find a card of your device. It's usually signed by the name you gave the vacuum cleaner when you installed it, like "Robot Vacuum" or "Living room vacuum." Click on this card to go to the cleaning control screen.

On the control screen, you'll see a room map, start buttons and battery status, but the model information you're looking for isn't displayed here yet. You'll need to go to the additional settings menu, and for that, look at the screen (usually at the top right) where the three dots or settings icon are located.

💡

Make sure your smartphone is connected to the same Wi-Fi network as the robot vacuum cleaner, although it is sometimes not necessary to view static information about the model, but the app may request synchronization.

Clicking on the menu icon will open up a list of options available, you can configure cleaning modes, schedules and voice packets, but we're interested in the technical part. Scroll down to General Settings or Device Settings. This is where the technical documentation of your gadget is hidden.

Search for information in the menu "About the device"

Inside the device settings menu, you need to find a item that is usually called “About Device”, “Device Information” or “Device Info”. The location of this item may vary slightly depending on the version of the Mi Home application and the regional account anchor.

When you go to this section, you'll see a technical summary, and this shows you the firmware version, MAC-The address, the time of operation and, most importantly, the model, often in alphanumeric code, for example, the model, roborock.vacuum.s5 or xiaomi.vacuum.mop2.

• 🤖 Model: Technical name of the model used by Xiaomi servers to identify the type of device.
• 🔢 SN: Serial Number, the unique identifier of your particular instance.
• 📡 MAC: Physical address of the network card to connect to the router.
• 🔋 Battery: Current status and battery charging cycles.

⚠️ Note: Do not confuse the device item in the vacuum cleaner settings with the account section in the application settings. The account profile stores data about the user, not about a particular gadget.

Importantly, in some versions of the interface, the model can be hidden under the Details button or only displayed when you click on the firmware version. If you only see (the software version), try clicking on that line several times - sometimes this opens a hidden engineering menu with full data.

If the model field has a strange code, don't panic. This is standard labeling practice. For example, dreame.vacuum.mc1808 matches the popular Dreame F9. Understanding these codes will help you find compatible filters and brushes in third-party stores.

Decoding of Xiaomi and Dreame model codes

Manufacturers in the Xiaomi ecosystem use a complex naming system, and robots can be produced under the Mi Robot, Roborock, Dreame, Viomi, Mijia, and others brands, often displayed in a unified way in the app, but the internal code tells the true story.

Model codes typically consist of a prefix of the brand’s model, such as the Roborock prefix pointing to Roborock devices (often sold as Xiaomi Robot Vacuum) and the Dreame lineup, and knowing the prefix helps you understand which branch of firmware and accessories you need.

Let’s look at the prefixes you can find in the About Device menu:

• 🏷️ Roborock.*: Flagship models, often sold under the Xiaomi brand (S5, S6, S7).
• 🏷️ dreame.*: Budget and medium-sized models with wet cleaning function (F9, D9, Z10).
• 🏷️ xiaomi.vacuum.*: Devices manufactured directly under the Mijia brand (Mop, Mop 2, 1S).
• 🏷️ Viomi.*: Robots from the Viomi sub-brand, often with voice assistant integration.

Special attention should be paid to devices labeled Global Version and Chinese Version. In the application, they may look the same, but the model codes will differ. Chinese versions often have the letter "C" or "CN" at the end of the code, while global versions have the letter "GL" or "EU" - this is critical when choosing firmware.

Alternative methods of identification through the application

If you don't feel complete enough in the About menu or want to double-check the data, there are alternative ways. The Mi Home app allows you to (view) information through the Add Device section. Press + to add a new gadget.

The app often shows hints on the list of available devices, so if your robot is in pairing mode, the system will suggest adding it, giving you the full marketing name, which can help you match the technical code with a beautiful name from the store.

Another method is to use widgets on the home screen of your smartphone. If you add a vacuum widget to your Android or iOS desktop, you can sometimes see brief model data that is duplicated from the app when you press it long enough and select "Information."

⚠️ Warning: When you try to add a device as new, don't complete the installation process unless you plan to reset.Just look at the name the system offers and cancel the action.

It’s also worth checking the “Shop” section inside the app, and sometimes when you go to the accessories store for your robot (the store icon is on the device menu), the full name of the model for which the items are selected may appear in the page title.

Problems with model definition and their solution

Users may encounter a situation where the model is not displayed or listed as "Unknown Device" in the app, which often occurs when using unofficial firmware versions or when connecting the Chinese version of the device to a European server.

In such cases, try changing the region in the app settings. Go to Profile → Settings → Region. If you choose China, try switching to your country or vice versa. Sometimes this causes the server to forward the correct metadata about the device.

• 🔄 Changing Region: Switching between servers can update your device profile.
• 🗑️ Remove and Re-Add: Remove the device from home and add again.
• 📲 App Update: Older version of Mi Home may not know new models.
• 🔌 Wi-Fi reset: Reset the network settings on the robot itself and reconnect it.

💡

If the app stubbornly doesn’t show the model and the robot is working, use a physical sticker on the bottom of the device – there’s always an exact model number (Model).

Sometimes the problem lies in the app's cache. Cleaning up the app's data in your Android settings (Settings → Applications → Mi Home → Memory → Clear cache) can help update the list of devices and their attributes. Don't be afraid to do a cache clean, it won't delete your cards and schedules, as they're stored on the server.

Why You Need to Know the Exact Vacuum Model

Many users ignore the technical model until they are faced with the need to replace the filter. Filters, brushes and sensors for roborock.s5 and roborock.s5e models can differ, despite the appearance of similarities. Buying an inappropriate consumable will result in the fact that it simply does not stand in place.

In addition, knowledge of the model is essential for finding specialized software. Enthusiasts often create modified firmware (such as Valetudo) that allows you to use a robot without the Xiaomi cloud. To install such firmware, the exact model is a critical parameter, since firmware for one model can turn another into a “brick”.

Accurate identification is also important when selling a device, and specifying the model technical code (e.g., "Xiaomi Vacuum Mop 2 Pro+ (SKV4136GL)") in the advert increases customer confidence and eliminates unnecessary questions in the comments.
