Abstract: A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.

Abstract: A chassis link has a link body, a ball joint socket being arranged at one link end of the link body. The ball joint socket has a cylindrical portion and an outwardly directed flange which is formed from the same material as and in one piece with the cylindrical portion. The ball joint socket is joined by way of the flange to a first web of the link body. A second lower web of the link body is joined to the cylindrical portion.
