Abstract
A cleaning apparatus comprising a housing, at least one agitator configured to be rotatably coupled to the housing, a combing unit comprising a plurality of spaced teeth configured to contact the agitator for preventing build up and removing debris, and a switch configured to cause the combing unit to move between an active mode in which the plurality of spaced teeth are configured to contact the agitator for preventing build up and removing debris, and an inactive mode in which the plurality of spaced teeth are configured to not contact the agitator. The switch may be configured to cause the combing unit to rotate about a pivot axis between the active mode and the inactive mode. The switch may be configured to convert linear motion of the switch into the rotational motion of the combing unit about the pivot axis.
