Abstract
A bottom cleaning system and apparatus for cleaning submerged portions of hulls includes a cyclically movable brush for operating in cleaning relation to a submerged hull portion while carried submerged in cleaning relation to the hull by an elongate member. Controls for operating the brush are disposed at a position remote from the brush whereby (fluid) connections can extend between the brush and the controls to be operated from the latter. An inflatable diaphragm provides a variably buoyancy which moves the brush between raised and lowered positions into and out of cleaning relation to the hull by controls disposed to be operated at a position remote from the brush. The elongate member can be formed as first and second articulated members whereby the brush can be pivotally operated using articulated movements. In addition, a plurality of such brushes and elongate members can be disposed and arranged on opposite sides of a hull so as to provide complete cleaning of the hull at a number of different locations.
