It is suitable for home, office and industrial scenarios. The sweeper consists of a sweeper body and a cleaning structure at the bottom. The sweeper body is equipped with a cleaning motor and a dust hopper. An air pump is provided in the dust hopper. A dust suction port and an exhaust port are provided on the surface of the dust hopper. A filter is provided on the air pump. The cleaning structure is installed on the drive shaft of the cleaning motor. The cleaning structure sweeps the dust and garbage on the road surface that the sweeper passes through to the vicinity of the dust suction port of the dust hopper. The air pump continuously draws air from the dust suction port, and the dust and garbage are sucked into the dust hopper together with the air. After that, the dust and garbage are blocked by the filter and remain in the dust hopper, and the air is discharged from the dust hopper from the exhaust port.
