An agitator (14) for use with cleaning machines, as well as methods for making the same, are shown and described. The agitator is configured to facilitate the removal of elongated fibers therefrom. In one embodiment, the agitator has a rotatable member with opposing first and second ends (30, 32), an axis of rotation extending between the first and second ends, and an external surface (34) extending at least partially between the first and second ends. A number of projections (36) are attached to the external surface of the agitator. One or both of the ends of the agitator are configured to rotatably engage the cleaning machine (10), such as at a bearing or other connector. The external surface of the rotatable member has a first portion that is substantially cylindrical about the axis of rotation, and a second portion separate from the first portion that has at least a first depression (42). The depression is configured to allow a user to insert a cutting tool partially into the depression and cut the fibers wrapped around the rotatable member.
