Dust Collector

摘要

A dust collector (1) for suctioning dust includes: an electric motor (5) for collecting dust; a power supply device (7) that supplies electric power to outside; a parameter detection device (13) that detects a parameter (hereinafter referred to as a "current parameter") which changes depending on a state of a supplied current supplied by the power supply device (7); a determination device (13) that determines whether or not a value of the current parameter detected by the parameter detection device (13) satisfies a condition based on a threshold value stored in a first storage unit; and a current supply starting device that starts current supply to the electric motor (5) when it is determined by the determination device (13) that the value of the current parameter satisfies the condition.
