Abstract

A vacuum cleaner, movable over a surface, includes a suction source, a suction port, and a dustpan attachment removably coupled to the suction port. The dustpan attachment includes a housing, a vacuum port, and a recess defined within the housing. The housing includes a top wall and a plurality of walls extending from the top wall to a bottom edge configured to contact the surface. The vacuum port extends through at least the top wall or one of the plurality of walls and is coupled to the suction port. When the bottom edge contacts the surface, the recess cooperates with the surface to form a suction channel having a suction inlet formed in a front of the housing and in communication with the vacuum port. The housing defines first and second ends. The bottom edge includes a sealing material that contacts the surface continuously between the first and second ends.
