Design & Features of the Xiaomi Mi Robot

The Xiaomi Mi Robot has a modern minimalist design. It is 13.5 inches in width, 3.8 inches of height and 8.4 lbs of weight. It has a smart «brain» with three powerful CPUs (ARM Cortex A7 Quad-Core processor, TI Digital Signal processor, and ST ARM Cortex M3 Microcontroller) called Simultaneous Localization and Mapping (SLAM) movement algorithm. The processors receive data from 12 different sensors that ensure the robot to build a layout of the cleaning area and calculate an efficient way of cleaning on its own. Powerful brushless DC motor delivers 1,800 Pa of suction power. When the map is created, the Mi Robot follows it navigating back-and-fourth in straight lines.

In the Mi Home app, you can watch how the Mi Robot builds a map and track its movements in real-time, see where it has cleaned and which areas are left to be done.

In the app, you can create virtual boundaries that will keep the Mi Robot from crossing the areas you choose. Also, with the latest update, the Xiaomi received a "zone cleaning" option. By drawing a rectangle on the created map, you set a zone where you want the robot to clean.

Smartphone App to control the Mi Robot

The Mi Robot has a Laser Distance Sensor (LDS) located on the top which allows it to scan all your rooms and create a detailed plan of your house. The sensor scans the perimeter of the room 360 degrees at 1,800 times per second. The laser creates an accurate map thanks to which the Mi Robot recognizes where it is.
