Abstract
A suction cleaner and an operation method thereof are provided. The suction cleaner includes a housing, a holding part, an impeller module, at least one sensing device, and a controller. An end of the housing has a dust-suction opening. The impeller module is located inside the housing, and a channel is located between the impeller module and the dust-suction opening. The controller is electrically connected to the sensing device to drive and adjust the rotation rate and the suction force of the impeller module, and thus the power consumption of the suction cleaner can be reduced.
