Camera in the robot vacuum cleaner Xiaomi: why it is needed and how to use

Xiaomi vacuum cleaner robots have long since ceased to be simple cleaning devices — they have turned into smart assistants with advanced navigation systems, artificial intelligence and even cameras. If you ever wondered why a robot vacuum cleaner needs a camera if it just drives on the floor, this article will dot the “i.” Spoiler: it’s not just for “beautiful photos” of your home.

The camera in the Mi Robot Vacuum-Mop 2 Pro, DreameBot L10s Ultra or Xiaomi Robot Vacuum X10+ has a number of critical functions, from mapping the room accurately to detecting obstacles and even monitoring safety. But how does that work? And can you do without it? Let's get down to the basics.

1.The main function of the camera: laser navigation and map construction

Xiaomi’s robot vacuum camera is designed to create an accurate map of the room in real time. Unlike budget models that rely on random algorithms (and often skip corners), camera devices use visual odometry technology (VSLAM). This means that the robot analyzes visual landmarks – furniture, walls, doors – and builds a new model. 3D-model of your apartment.

How does this work? For example, Xiaomi Mi Robot Vacuum-Mop 2 Ultra scans a room at up to 30 frames per second, comparing new images with those already saved.

• 📍 It accurately determines its location with an error of up to 1-2 cm.
• 🔄 Remembers several floors (if multi-card is supported).
• 🚫 Avoiding re-travel in the same areas.

Without a camera, the robot would have to use less precise techniques, such as gyroscopes or infrared sensors, which often make mistakes on complex surfaces (carpets, tiles with a pattern), while the camera allows the device to “see” the room almost like a human.

2.Obstacle recognition: why the robot does not run into socks and wires

The second key feature of the camera is the identification of obstacles. Xiaomi robots with support for AI Obstacle Avoidance (for example, DreameBot Z10 Pro) can recognize:

• 🧦 Socks, shoes, toys.
• 🔌 Wires and cables (even black on the dark floor!).
• 🐾 Liquids (shed tea, puddles of flowers).
• 🚪 Doorways and sills.

How does this happen? The camera sends the image to the processor, where the neural network analyzes objects and classifies them, so for example, if the robot "sees" the cord, it either skirts it, or pauses cleaning and sends a notification to the Mi Home app with a photo of the obstacle, which is especially useful for homes with children or animals, where small objects often appear on the floor.

By comparison, robots without a camera (such as budget models with collision sensors) just run into an obstacle and then try to get around it, which is not only less efficient, but also fraught with breakdowns — for example, if a robot hooks a wire and pulls a lamp behind it.

💡

If your Xiaomi robot vacuum cleaner often “cannot see” black wires, turn on the application’s settings to “High Sensitivity to Dark Objects” to increase recognition accuracy, but may slightly reduce the speed of cleaning.

3.Safety monitoring: Can the camera be used as a "nanny"?

Many users don't realize that a robot vacuum cleaner camera can work as a surveillance device, such as the Xiaomi Mi Robot Vacuum-Mop 2 Pro and later, which has Patrol Mode.

• 📹 Take a photo or video on a schedule.
• 🚨 Sends notifications when motion is detected.
• 🔒 Save pictures to the cloud (if sync with Mi Home is enabled).

This will not replace a full-fledged camera, but it can be useful for:

• 🐶 Control of pets.
• 👶 Check if the children have wandered into the restricted area.
• 🚪 Monitoring doors/windows (if the robot passes by them).

Important: The robot vacuum cleaner camera does not record continuously; it only activates during cleaning or patrolling, and the viewing angle is limited (usually 120-170°), and the image quality depends on the lighting.

⚠️ Note: If you plan to use a robot as a surveillance device, please note that in some countries (e.g. the EU) it may violate privacy laws!

4.Smart functions: recognition of rooms and cleaning areas

The camera allows the robot to not only avoid obstacles, but also recognize the types of rooms. For example, the firmware of new models (Xiaomi Robot Vacuum X10+, DreameBot L10s Ultra) implements Room Recognition.

• 🛏️ Bedroom (according to the presence of a bed, bedside tables).
• 🚽 Bathroom (by tile, toilet).
• 🍽️ Kitchen (on the table, chairs, refrigerator).

Why do you need this? To automatically adjust the cleaning mode:

The camera also helps the robot remember special areas, for example, if you manually mark the “no cleaning zone” (where the documents are located or the aquarium is located) in the Mi Home app, the robot will bypass it even after the reboot.

5. Can I turn off the camera and how to do it?

Not everyone likes the idea that a robot vacuum cleaner is spying on their house, and fortunately, you can turn off the camera, either completely or partially.

At the Mi Home appendix:

1. Open the card of your robot vacuum cleaner.
2. Go to Settings. → Confidentiality.
3. Turn off the options: 📷 Video footage during cleaning 🔍 Identification of obstacles (AI) 🗺️ Keeping maps in the cloud

On some models (such as the DreameBot L10s Ultra), you can also physically close the camera with a special plug that comes with the kit.

• ⚠️ Without a camera, the robot will lose its ability to navigate accurately and use less efficient sensors.
• ⚠️ Obstacle and room recognition functions will be turned off.
• ⚠️ Cleaning time can increase by 30 to 50%.

1. Save the current room map manually

2. Set up virtual walls in the app

3. Check the operation of the collision sensors

4.Be prepared for more frequent robot "stuck-->

Myths and Reality: What the Camera Can't Do

There are a lot of myths surrounding the cameras in the robot vacuum cleaners, and let's figure out what's true and what's not.

Myth 1: “A robot is spying on me and sending pictures to China”

🔹 Reality: Xiaomi claims that all data (photos, maps) is stored locally on the robot or in the user account, and transfers to the cloud only occur if you explicitly enable synchronization. However, there have been cases of data leaks from some Xiaomi devices in 2020, so it is recommended to disable cloud-based card storage if it is not needed.

Myth 2: “The camera works at night and illuminates the room”

🔹 Reality: The robot vacuum cleaner camera has no infrared illumination and can't see in complete darkness, needs at least a minimum level of lighting (like night lights) to work. In the dark, the robot switches to collision sensors.

Myth 3: “The camera recognizes faces and records conversations.”

🔹 Reality: There is no evidence that Xiaomi’s robot vacuum cleaners use facial recognition, and their cameras are low-resolution (usually, the most common). 720p) As for sound, most models don't have a microphone (except for the Xiaomi Mi Robot Vacuum-Mop 2 Pro, where it is only used for voice commands).

⚠️ Note: If you are paranoid about privacy, choose a camera-free model (e.g. Xiaomi Mi Robot Vacuum). 1C with laser rangefinder) or use a plug for the lens.

7. Comparison with alternatives: Laser (LiDAR) vs Camera

The camera is not the only navigation technology in robot vacuum cleaners. Many Xiaomi models (such as the Mi Robot Vacuum-Mop P) use a laser rangefinder (LiDAR).

Which option should I choose?

• 🏠 For apartments with good lighting and many small obstacles (toys, wires) camera is better suited.
• 🌑 For large houses with dark rooms or open plan – LiDAR.
• 💰 If you have a budget, look for hybrid models (like DreameBot). D9), where both the camera and the laser are combined.

💡

The camera is better suited for smart object-recognition cleaning, and LiDAR is better suited for precise navigation in complex environments, ideally with both.
