  • Publication number: 20180255991
    Abstract: A surface cleaning apparatus including a body defining an agitation chamber, an agitator partially disposed within the agitation chamber and configured to rotate about a pivot axis, and a debrider at least partially disposed within the agitation chamber. The agitator includes an elongated body having a first and a second end, a sidewall extending radially outward from the elongated body extending between the first and the second ends, and a plurality of bristles extending radially outward from the elongated body. The plurality of bristles are arranged in at least one row adjacent to the sidewall. The debrider includes a plurality of teeth configured to contact a portion of the sidewall as the agitator rotates about the pivot axis.

  • Publication number: 20170347848
    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.

  • Publication number: 20170127896
    Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) 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 leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.
