VACUUM CLEANER

PROBLEM TO BE SOLVED: To provide a vacuum cleaner detecting a dust amount with higher accuracy by reducing a blind area of a photosensor without additionally providing a photosensor.SOLUTION: The vacuum cleaner includes an air course W communicating with a suction side of an electric blower. The vacuum cleaner includes a light emitting element 35 emitting light, and a light receiving element 36 receiving the light from the light emitting element 35 through the air course W, and includes the photosensor detecting the dust amount passing through the air course W based on a light reception amount in the light receiving element 36 of the light from the light emitting element 35. The vacuum cleaner includes a light emission side reflector 39 making a cross section of the light from the light emitting element 35 larger than project areas S1, S2 of the light emitting element 35 and the light receiving element 36. The vacuum cleaner includes a light reception side reflector 42 narrowing the cross section S3 of the light emitted from the light emitting element 35 through the light emission side reflector 39 and making the light receiving element 36 receive the light.
