For Xiaomi Mijia 1S robot vacuum cleaner, the laser sensor still plays a main role in the whole path planning process. It scans the environment at a high speed of 5*360°/sec and accurately determines the moving direction and the current position in horizon, building a map restoring the full view of your home.

The visual sensor is located obviously at the top of the robot. It plays an auxiliary role in extracting image feature information, modeling and positioning things, enduing the robot cleaner with image recognition ability and room area division ability.
