Embodiment Construction

[0029] According to some embodiments of the present disclosure, a cleaning device includes a combing unit (also referred to as a cleaning unit or ribs) that includes a series of spaced protrusions or teeth extending into a cleaning roller to prevent buildup and remove debris. Debris (eg, hair, thread, etc.). The protrusion extends along a majority of the cleaning roller and extends partially into the cleaning roller to intercept debris as it passes around the roller. The protrusion has an angled leading edge that is not aligned with the center of rotation of the cleaning roller and is directed in or against the direction of rotation of the cleaning roller. The shape and configuration of the combing unit and protrusions are designed to facilitate the removal of debris from the cleaning roll with minimal impact on the operation of the cleaning apparatus. The cleaning equipment may include an upright vacuum cleaner or sweeper or the surface cleaning head of a robotic vacuum clea...
