Abstract: A chalkboard eraser cleaner including a completely closeable, box-like housing containing an electrically driven, rotatable beater. At the top of the container is a side, slot-like opening with a door for the insertion of the eraser to be cleaned. Right below the area in which the eraser is inserted, there is an eraser support surface of somewhat slack, mesh netting material supported between the walls of the container for supporting the eraser during beating, with the mesh netting located directly above the rotatable beater whose arms impact the bottom of the eraser through the mesh netting to clean the eraser. Below the beater and the mesh is a removable drawer located at the bottom of the container which can be removed for the disposal of the eraser dust, which generally will fall into the drawer during use of the cleaner. An electrical contact switch is positioned in the container adjacent to the forward end of the area in which the eraser to be cleaned is inserted.
