ABSTRACT:
A cleaning apparatus includes an elongate rod defined by a proximal end portion having a first linkage member and an opposed distal end portion. The first linkage member is pivotally coupled to a second linkage member of a cleaning head. There is a biasing assembly that is coupled to the elongate rod and to the cleaning head, which tensions the cleaning head to a maximum pivotal excursion relative to the cleaning rod.
