Why Xiaomi vacuum cleaner needs a camera: 7 non-obvious features you didn’t know about

Have you ever wondered why today's Xiaomi robot vacuum cleaners are equipped with cameras like smartphones? At first glance, this seems redundant: do you need eyes to clean the floor? Turns out, the camera in the vacuum cleaners Mi Robot, Dreame or Viomi is not a marketing ploy, but a key element that turns the device from a random "vacuum cleaner" into a smart assistant with artificial intelligence.

In this article, we will discuss 7 real-world tasks that the camera solves in Xiaomi vacuum cleaners – from building accurate maps of the room to recognizing objects and integrating with the smart home system. LDS, VSLAM and 3D ToF, why some models don't have a camera, and how to protect their privacy if a robot is spying on your house, and the myth that a camera is only for avoiding obstacles (spoiler: less than 20% of its capabilities).

Building a room map: how a camera replaces a laser rangefinder

The main function of the camera in Xiaomi vacuum cleaners is to create a detailed map of your apartment. But how does it work in practice? It depends on the technology:

• 🔍 VSLAM (Visual Simultaneous Localization and Mapping: The camera analyzes visual landmarks (wall corners, furniture, wallpaper drawings) and builds a map in real time. Used in Mi Robot Vacuum-Mop 2 Lite or Dreame models D9.
• 📡 LDS + camera: laser scanner (LDS) It defines distances, and the camera adds color and textures. This is how the Xiaomi Mi Robot Vacuum-Mop 2 Pro works.
• 🎯 3D ToF (Time-of-Flight): A camera with deep scanning (like an iPhone with LiDAR) creates a camera with a full-scale camera. 3D-A model of the room. Z10 Pro.

Without a camera, the robot navigates blindly - like the first Xiaomi Mi Robot models 1S, They just rode around the room randomly until they run into an obstacle, and with a camera, the vacuum cleaner remembers the location of the furniture, optimizes the cleaning route, and can even save several maps (for example, for different floors).

By the way, camera-built maps are often more accurate than laser ones – they are better at recognizing transparent or shiny surfaces (such as glass tables or mirrors) that are not easily visible. LDS-The scanners sometimes don't see, but there's a downside: in total darkness, visual navigation (VSLAM) This is why some models (for example, Viomi) are worse. V3) turn on the lighting automatically.

2.Recognition and avoidance of obstacles: why the vacuum cleaner won't get stuck in shoelaces

The second key task of the camera is to identify objects that can interfere with cleaning.

• 🧦 Socks, laces, wires – the robot will go around them or stop so as not to wind on the brush.
• 🐾 Animals and their bowls – some models (e.g. DreameBot) L10s Ultra even distinguishes cat from dog!
• 🪑 Low furniture (chairs, pooficas) – the camera assesses the height and decides whether the vacuum cleaner will crawl under them.
• 🚪 Doors and stairs – so as not to fall from a height or get stuck in a doorway.

The technology works thanks to neural networks trained on thousands of images of household items, such as in Xiaomi vacuum cleaners with a Qualcomm chip. APQ8053 algorithm YOLO (You Only Look Once, which analyzes the frame in 0.02 seconds and decides whether to move or stop.

💡

If your vacuum cleaner often "does not notice" obstacles, check the cleanliness of the camera - the dust on the lens reduces the accuracy of recognition.

Interesting fact: in the Dreame models, a subsidiary of Xiaomi, the camera can recognize color tags. For example, if you put a red mat on the floor, the robot will go around it like a forbidden zone - without having to build virtual walls in the application.

3. 3D-Scanning for Precise Cleaning: Why Some Vacuum Cleaners “See” Dust

Cameras in top Xiaomi models (for example, Mi Robot Vacuum-Mop 2 Ultra or DreameBot) X30 Ultras are equipped with structured light or ToF sensors that create a three-dimensional map of the room:

• 📏 Measure the height of carpets – to automatically increase suction when switching from laminate to pile.
• 🧹 Determine the level of pollution – the camera captures the accumulation of dust in the corners and adjusts the route.
• 🚫 Avoiding “invisible” obstacles, such as the thin legs of chairs or wires on a dark background.

Technology 3D ToF works like a radar, where the camera emits infrared rays and measures the time they reflect, and it allows you to build a map with an accuracy of 1 mm — for example, DreameBot. Z10 Pro can distinguish a stain of dirt from a shadow and give it more attention when cleaning.

It is important to understand that not all cameras are the same, for example, budget models (such as the Mi Robot Vacuum-Mop Essential) use a simple camera with a resolution. 720p, which only helps LDS-And in flagships (like DreameBot) L10s Ultra is a 13-megapixel camera with autofocus and night mode – it not only builds a map, but also transfers the image to the Mi Home app.

4.Integration with a smart home: how a vacuum cleaner becomes the "eyes" of your apartment

Xiaomi's vacuum cleaner camera is not only a cleaning tool, it's also part of the smart home ecosystem. Here's how it's used:

• 🏠 Control via app: You can see a real image from the vacuum cleaner camera in the Mi Home or Dreame App – for example, to check if you forgot to turn off the iron.
• 🔄 Automation by Events: A vacuum cleaner can start cleaning if the camera detects that you are not at home (integration with Mi Band or geo-fences).
• 🚨 Security feature: Some models (e.g. DreameBot) L10s Ultra can send notifications if the camera notices movement in your absence.

Example of automation settings:

If [Camera vacuum cleaner detected movement] and [All family members outside the house (by geolocation)] →


Then [Enable Smart Speaker Siren] + [Send Notification to Smartphone]

These scenarios work through Mi Home Automation or Apple HomeKit (for models with HomeKit Secure Video support).

But this raises the question of privacy, and the vacuum cleaner camera could theoretically become a surveillance tool if it gets hacked.

⚠️ Warning: Always update the vacuum cleaner firmware through Settings → Update in Mi Home, outdated versions of the software are vulnerable to MiTM attacks, and disable access to the camera in the app settings if you are not using it.

5.Why do some Xiaomi vacuum cleaners do without a camera?

Not all Xiaomi robot vacuum cleaners are equipped with cameras, here are 3 reasons why the brand produces models without it:

• 💰 Price: Camera + The cost of an image processor is 20 to 30 percent higher than the cost of a low-end model (such as the Mi Robot Vacuum-Mop Essential) LDS-scanner.
• 🔋 Autonomy: Video processing requires a lot of energy. Vacuum cleaners without a camera last up to 180 minutes versus 120-150 minutes for models with a single camera. VSLAM.
• 🛡️ Privacy: Some users avoid cameras because of the risk of data leakage.For them, Xiaomi offers models with laser navigation (for example, Mi Robot Vacuum). X10+).

Also, the camera is not needed if the vacuum cleaner:

• It works in small rooms (up to 50 m2), where a gyroscope or infrared sensors are sufficient.
• It is used only for dry cleaning (without the wash function - the camera is often needed to recognize wet areas).
• It is designed for cleaning in the dark (for example, at night) where VSLAM worse LDS.

Look for models with LDS-Scanner (for example, Mi Robot Vacuum) X10+)

Check for support for saving cards in the application

Make sure there are obstacles avoidance sensors (such as ToF or infrared)

Pay attention to the time of operation (without the camera it should be) ≥150 minutes)

-->

Unless you need a bell and whistle, like, 3D-scanning, but the accuracy of cleaning is important, the best choice is vacuum cleaners with hybrid navigation (laser) + gyroscope, for example, Xiaomi Mi Robot Vacuum-Mop P. They are cheaper than chamber models, but not inferior to them in efficiency on standard apartments.

6.Myths and truths about cameras in Xiaomi vacuum cleaners

There's a lot of rumors going around the cameras in the robot vacuum cleaners.

⚠️ Warning: If you see “instructions” on the Internet to turn off the camera in Xiaomi vacuum cleaners by flashing it is a scam! Branded software does not allow you to completely deactivate the camera, and unofficial firmware deprives you of warranties and opens access to your home network.

Another common fear is that a vacuum cleaner camera can record video without you knowing it.

• In most Xiaomi models, the camera is activated only during cleaning or on command from the app.
• The video stream is not saved on the device (except for models with security function, where the recording is only when the motion sensor is triggered).
• To broadcast the video, explicit user confirmation is required in the Mi Home app.

💡

Xiaomi’s vacuum cleaner camera isn’t the default spy device, but its security depends on the relevance of the firmware and your privacy settings in the app.

7. How to protect your privacy if there is a camera in the vacuum cleaner?

If you are concerned that Xiaomi vacuum cleaner can “snoop” on your home, follow these guidelines:

Turn off camera access in the Mi Home app settings (Device) → Settings → Permits)

Set a password on the Wi-Fi network of the vacuum cleaner (in the router settings)

Regularly update the firmware through Settings → Update of the PO

Do not use a vacuum cleaner in rooms with confidential information (for example, in a home office)

Stick opaque film on the camera if you do not use its functions

-->

Additional measures for paranoids (or those who are really afraid of hacking):

• 🔌 Physical Disconnection: In some models (e.g. DreameBot) L10s Ultra camera can be disabled hardware, removing the top cover and disconnecting the plume (but this will deprive you of warranty).
• 🌐 Network isolation: Connect the vacuum cleaner to a separate Wi-Fi network (guest or second router) without access to other devices.
• 📱 Alternative firmware: There are custom firmware (like Valetudo) that block data transfer to the Xiaomi cloud, but installing them requires skills and voids warranty.

If you still decide to completely abandon the camera, but want to keep the accuracy of navigation, pay attention to models with pure laser navigation:

• Xiaomi Mi Robot Vacuum X10+ (LDS + gyroscope, no camera)
• Dreame D9 Max (LDS + ToF sensor to avoid obstacles)
• Viomi V2 Pro (LDS + ultrasonic)

Remember, the camera is a tool, and its security depends on how you use it, and if you follow basic precautions, the risk of data leakage is minimal, and the benefits of smart cleaning are maximum.
