1. A self-moving cleaner comprising:
- a main body;
an intake opening for suctioning therethrough dust collected on a surface to be cleaned;
an electric blower for generating airflow to suction the dust;
a dust receiver for collecting the dust suctioned through said intake opening;
a drive motor;
a roller to be driven by said drive motor;
a power source for supplying electric power to said electric blower and said drive motor;
a sensor for optically detecting a distance to an obstacle; and
an enclosure containing therein said electric blower, said dust receiver, said power source, and said sensor, wherein said enclosure is entirely transparent or entirely semi-transparent such that said sensor can transmit and receive light through said enclosure.

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.

9. A self-moving cleaner comprising:
-
a main body;
a moving device for moving said main body;
a direction sensor for detecting a moving direction of said main body;
distance sensors disposed at a forward section and a side of said main body for measuring a distance to an obstacle around said main body;
a battery defining a power source;
a travel control device for controlling said moving device according to an output of said direction sensor and any of said distance sensors such that (i) said main body turns and travels alongside a wall of a room when any of said distance sensors disposed at the forward section of said main body detects the wall, (ii) designated as a reference direction is a direction of movement of said main body at a time when outputs of said distance sensors disposed at the side of said main body are generally in agreement, and set as a reference for output of said direction sensor is the direction of movement of said main body, and (iii) determined is that said main body has completed a full round alongside walls of the room, when said main body has traveled for a predetermined time after said direction sensor has detected the moving direction of said main body as being the reference direction; and
an enclosure containing therein said distance sensors, said travel control device and said battery, with said enclosure being entirely transparent or entirely semi-transparent.
