Apparatus as claimed in claim 1 wherein said float assembly comprises one or more annular floats. 5. Apparatus as claimed in claim 4 wherein said float assembly comprises a plurality of annular floats arranged one above the other. 6. Apparatus as claimed in claim 1 wherein said suction head is provided with a central outlet on its upper side for connection to an inlet of said pump, said pump being mounted for movement relative to the suction head between a position where the pump inlet is adjacent to the suction head outlet and communicates therewith and a position where the pump inlet is moved clear of the suction head outlet. 7. Apparatus as claimed in claim 1 wherein said suction head is of domed configuration in cross-section. 8. Apparatus as claimed in claim 1 wherein said capturing means includes slide means whereby said at least one elongated member is captured for sliding movement relative to said float assembly. 9. Apparatus as clamed in claim 1 wherein said guide means comprises a pair of said upright elongated members, said elongated members being pivotally connected at their lower ends to opposite ends of the suction head assembly respectively, each said elongated member being captured to said float assembly for substantially vertical raising and lowering movement relative thereto. 10. Apparatus as claimed in claim 1 wherein said means for raising and lowering said suction head assembly comprises a winch mounted to or on said float assembly, said winch having a winch cable coupled centrally to said suction head assembly. 11. Apparatus as claimed in claim 1 and including means for moving said apparatus in one direction in said liquid reservoir, and means for automatically reversing the direction of movement of said apparatus in said liquid reservoir. 12. Apparatus for removing materials settling in or suspending in liquid in a liquid reservoir, said apparatus comprising: a float assembly, said float assembly including at least one annular float having a central opening, a suction head assembly beneath said float assembly, said suction head assembly including: an elongated suction head having a hollow interior and an open lower side defining an entrance mouth, a suction pump mounted to said suction head and adapted to communicate with said hollow interior of said suction head, said pump being operable to create a suction pressure in said suction head to draw in said materials through said mouth and pump said materials to a remote location, and a pair of skids at respective opposite ends of said suction head and extending forwardly and rearwardly thereof, guide means between said suction head assembly and said float assembly for guiding movement of said suction head assembly in a vertical direction, said guide means including a pair of elongated substantially parallel guide members, said guide members being pivotally connected at their lower ends to opposite ends of said suction head assembly, and means for raising and lowering said suction head assembly relative to said float assembly, said raising and lowering means including a cable extending through said central opening in said float assembly and coupled centrally to said suction head assembly intermediate the ends thereof, said raising and lowering means supporting said suction head assembly and permitting operation of said suction head between a raised position in which said suction head assembly located adjacent said float assembly, a lowered position in which said suction head assembly is located adjacent to a floor surface of said reservoir and intermediate positions between said raised and lowered positions. 13. Apparatus as claimed in claim 12 wherein said elongated guide members comprises a pair of spaced apart substantially upright guide members arranged at opposite sides of and being mounted for slidable movement relative to said float assembly in a substantially vertical direction. 14. Apparatus as claimed in claim 13 wherein said float assembly comprises a frame connected to said at least one annular float and spaced apart slide assemblies on said frame and capturing respective said guide members for slidable movement relative to said float assembly. 15. Apparatus as claimed in claim 14 wherein said frame of said float assembly is provided with spaced apart skids and wherein in the raised position of said suction head assembly, said skids of said suction head assembly are located inwardly of the skids of said float assembly. 16. Apparatus for removing materials settling in or suspending in liquid in a liquid reservoir, said apparatus comprising: a float assembly, said float assembly including a support frame and an annular float member mounted to said support frame, said annular float member having a central opening, a suction head assembly located substantially vertically centrally beneath said float assembly, said suction head assembly including: an elongated suction head having a hollow interior and an open lower side defining an entrance mouth, said suction head having a domed upper surface, and a central opening in said domed upper surface, a suction pump mounted to said suction head and adapted to communicate with the hollow interior of said suction head through said central opening and an outlet duct extending from said suction pump, said pump being operable to create a suction pressure in said suction head to draw in said materials through said mouth and pump said materials through said outlet duct to a remote location, and skids extending forwardly and rearwardly of said suction head, an electric winch mounted to said support frame means, said winch including a winch cable connected centrally to said suction head assembly, said winch cable being arranged to pass through said central opening in said annular float member, guide means between said suction head assembly and said float assembly for guiding movement of said suction head assembly towards and away from said float assembly, said guide means including a pair of substantially upright elongated guide members, a first said guide member being pivotally connected at its lower end to one end of said suction head assembly and a second said guide member being pivotally connected at its lower end to the other end of said suction head assembly, first and second spaced apart slide assemblies mounted to said support frame, said first and second guide members passing respectively through said first and second slide assemblies whereby to be guided thereby during their movement, said winch being operable to move said suction head assembly between a raised position in which said suction head assembly located adjacent said float assembly for collecting material adjacent the surface of liquid in said reservoir, a lowered position in which said suction head assembly is located adjacent to a floor surface of said reservoir and intermediate positions between said raised and lowered positions and wherein said upright elongated members further comprise depth indicating means for visually indicating the depth of operation of said suction head assembly in said liquid reservoir, and means for moving said apparatus in one direction in said liquid reservoir, and means for automatically reversing the direction of movement of said apparatus in said liquid reservoir. 17.
