A lid assembly and method for removing articles from a floor. The lid assembly includes a lid assembly base structure, a fastening device for securing the lid assembly base structure to a storage cart, and a platform riser that forms a support platform at a distal end. The lid assembly further includes a collector arrangement. The collector arrangement is pivotally attached to the support platform and includes a collection panel. With the collection panel, the collector arrangement provides a convenient method for quickly gathering large quantities of articles from the floor and directing them entirely to a storage cart. Operatively, in a retracted position, the collection panel covers an opening through the storage cart. Alternatively, in an extended position as the storage cart is oriented in a horizontal position in contact with the floor, the collection panel exposes the opening through the storage cart and defines a pathway for directing articles from the floor, upwardly across the collection panel, downwardly to the lid assembly base structure, and through the opening. In one exemplary embodiment, a lid assembly is integral to a collection system for receiving articles.
