A dust detector in a vacuum cleaner includes a light-emitting element exposed into a dust suction passage for emitting a light beam into the dust passage, and a light-detecting element exposed into the dust suction passage for detecting the light beam emitted from the light-emitting element. A detector unit detects the amount of dust flowing through the dust suction passage based on the intensity of the light beam transmitted from the light-emitting element across the dust suction passage to the light-detecting element. The light-emitting element and the light-detecting element are covered respectively by a pair of light-transmissive covers having respective end faces exposed into the dust suction passage and lying flush with an inner wall surface of the dust suction passage.
