Abstract
A rotary brush sweeper includes a rotary brush which is rotatable about a brush axis and which may be of generally cylindrical form. The rotary brush is supported in a brush support assembly that is pivotable about a central axis, with the brush axis being offset from the central axis. As a result, rotation of the pivotable brush support assembly accomplishes the raising or lowering of the rotary brush with respect to a surface being cleaned. In a preferred configuration, the pivotable brush support assembly includes a pair of spaced support members having respective annular convex mounting surfaces. The spaced support members are received within respective annular concave mounting surfaces situated on a housing structure for the sweeper.
