Devices and processes for axial disentanglement of debris from a rotatable mechanical agitator generally includes a cleaning member including a top stem portion, an intermediate cutting portion, and a bottom base portion; and a cylindrically-shaped mechanical agitator rotatably mounted within a head unit. The mechanical agitator includes one or more channels extending along a longitudinal axis and the head unit includes a slot opening coaxially aligned with a channel when in use. The bottom base portion and the intermediate cutting portion are configured to traverse a length of the one or more channels, wherein the intermediate cutting portion is positioned to cut debris entangled on the mechanical agitator when the top stem portion slidingly engages the slot opening in the head unit.
