Dust collector and cleaning device

Abstract

This invention addresses the problem of poor waste collection functionality in conventional cleaning devices. The dust collection box comprises: a box-shaped structure with an interconnected receiving space and an opening, the receiving space being defined by the interior of the dust collection box; the opening is located at the front of the dust collection box for sweeping waste into the receiving space through the opening; optionally, the dust collection box further includes a first auxiliary wheel for contacting the surface to be cleaned. This invention enables easy collection of dirt.
