Abstract
A self-moving cleaner has a main body and comprises an intake opening for suctioning dust, an electric blower for generating airflow to suction dust, a dust receiver for collecting the dust suctioned by the electric blower, rollers driven by drive motors, a power source for supplying electric power to the electric blower and the drive motors, and sensors for optically detecting a distance to an obstacle. An enclosure surrounds the main body, the electric blower, the dust receiver, the power source, and the sensors, wherein the enclosure is transparent or semi-transparent, and the sensors transmit and receive light through the enclosure.
