A cleaner having an optical sensor is provided to improve air purifying efficiency in a day time by increasing the speed of a fan. A cleaner having an optical sensor includes cases(110,120), a fan(130), an optical sensor(210), a microcomputer(220), and a plurality of filters(150,160,170,180,190). The cases(110,120) are coupled with a pair of covers(110,120) and has a hollow part in the inner side of the cases. The cases(110,120) have absorption holes(111,121) and a discharging hole(112). The cases(110,120) include a front cover(110) and a rear cover(120). The cases(110,120) include a hollow part through combination of the front cover(110) and the rear cover(120). The absorption hole(111) is included in the lower part of the front cover(110). The rear cover(120) has an upper part including the discharging hole(112) and a lower part including the absorption hole(111). |
