<P>PROBLEM TO BE SOLVED: To provide a suction cleaner reducing the running time of the charged suction cleaner, and an operation method thereof. <P>SOLUTION: 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 holding part is connected to the housing. The impeller module is located inside the housing, and a channel is located between the dust-suction opening and the impeller module. The controller is electrically connected to the sensing device to drive the impeller module and adjust the rotation rate and the suction force thereof, and thus the power consumption of the suction cleaner can be reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
