Apparatus and method for cleaning a surface with a fluid

An apparatus for cleaning a surface with a fluid, the apparatus comprising:

• a hydrodynamically shaped housing configured for movement over a submerged surface;
• a fluid inlet connector connectable to the housing, the fluid inlet connector defining a fluid inlet configured to receive a flow of fluid from a source of fluid;
• a radial flow turbine disposed within the housing and configured to receive the flow of fluid from the fluid inlet, the radial flow turbine rotatably mounted about an axis of rotation to rotate and produce a pulsating flow of fluid;
• a pole connection adapted to releasably couple to an elongated pole for manual movement of the housing, wherein the pole connection includes a swivel joint to allow pivoting movement relative to the housing;
• one or more fluid channels each configured to receive the pulsating flow of fluid from the radial flow turbine;
• and
• one or more nozzles each configured to receive the pulsating flow for fluid from a corresponding one of the one or more fluid channels and discharge a pressurized spray of fluid from the housing.

An apparatus for cleaning a surface with a fluid, which comprises:

• a housing defining a plurality of nozzles;
• a cap coupled to the housing, the cap defining a fluid inlet configured to receive fluid from a fluid source;
• a turbine chamber defining a plurality of chamber outlet ports;
• a radial flow turbine mounted within the turbine chamber, the radial flow turbine defining a plurality of chambers configured to receive the fluid from the fluid inlet and configured to rotate about an axis of rotation and produce a pulsating fluid flow for distribution through the chamber outlet ports of the turbine chamber;
• and
• a plurality of fluid channels coupled to the chamber outlet ports and in fluid communication with the nozzles of the housing, the fluid channels configured to receive the pulsating fluid flow and direct the pulsating fluid flow to the nozzles of the housing wherein the nozzles discharge the pulsating fluid flow as a pressurized spray to facilitate cleaning of a submerged surface.
