PURPOSE:To clean air with good efficiency by detecting a direction where there is a person and turning a suction hole toward the direction with rotating means. CONSTITUTION:The air is sucked with a fan motor 21 from the suction hole arranged to a main body to clean the air with the cleaning means, and this cleaned air is blown from a blowing hole arranged to the main body to clean the inside of a room. Then, the person is detected by scanning inside of the room with a sensor 28 having directivity from the main body. Further, the above suction hole is turned to the direction where the person is detected with the sensor 28 through the rotating means 47. As a result, air can be cleaned with good efficiency. |
