Teardown: Xiaomi Mi Robot Vacuum
A closer look inside the Xiaomi Mi Robot Vacuum that is set to take on the Roomba.
Xiaomi recently introduced its $250 Mi Robot Vacuum that hopes to take on the iRobot Roomba. The Mi Robot Vacuum can clean all floor types and features Laser Distance Sensor (LDS) and Simultaneous Localization and Mapping (SLAM) to scan its surroundings 1,800 times per second in 360 degrees.
It also has 12 sensors, including ultrasonic radar, cliff sensor, gyroscope and accelerometer, three processors and four CPU cores for real-time mapping and positioning, and a main brush with adjustable height for uneven surfaces.
The Xiaomi Mi Robot Vacuum features a Nidec brushless DC motor, claims to be ultra quiet, and uses a 5,200 mAh battery that promises 2.5 hours of cleaning. Like other Mi Ecosystem products, Mi Robot Vacuum pairs and integrates with the Mi Home app. It can be controlled remotely where users can remotely power it on or off, and it also lets you set regular cleaning schedules.
We’ve already compared Xiaomi to the Roomba and Dyson 360 Eye (read comparison here) and thought it’d be fun to take a closer look inside the Mi robot vacuum.
