Abstract: A dustpan or tray having a front edge to be held against the surface to be cleaned and the dirt or debris is adapted to be swept across the front edge into the pan. A resilient roller is mounted for rotation on the under surface of the pan and extends generally parallel to the front edge. The roller aids in positioning the front edge at the proper angle during sweeping of debris into the pan and, after sweeping, the roller is adapted to be rolled over the ridge of residual dirt remaining on the surface. The residual dirt clings to the roller so that all of the residual dirt can be removed.
