Abstract
A cleaning device with sweeping and vacuuming functions includes a body accommodating a sweep module and a vacuum module. A main brush and an auxiliary brush driven by a power unit are pivoted in the sweep module. The main brush partially extends outside an opening at a bottom of the sweep module and contacts a ground surface. The sweep module has an outlet adjacent to a top of the auxiliary brush, and is pivoted in the body to freely and pivotally swing under weight. A first chamber of a dust collector of the vacuum module has an inlet corresponding to the outlet, and trash removed by the sweep module is collected into the first chamber. An air inlet communicating with an air intake component is formed above a second chamber of the dust collector. A suction port is formed below the second chamber to draw dust into the second chamber.
