Abstract
A cleaning device includes a housing assembly and a teeth assembly. The housing assembly includes an upper section and a lower section configured to receive the teeth assembly therebetween. The lower section includes an outer edge. The teeth assembly includes an outer section and an inner section, which are movable in opposite directions of each other. The outer section includes a teeth member extending from the housing assembly and abutting the outer edge. In a rested state, the teeth member is biased away from the housing assembly and extends substantially beyond the outer edge. In an engaged state, the teeth member is retracted and is positioned substantially inward of the outer edge while debris is removed from the teeth member by the outer edge.
