1. An automatic swimming pool cleaner comprising: a. a body configured for travel along a surface to be cleaned and defining an inlet for receiving pool water; andb. first means, (i) configured for rotation about an axis generally perpendicular to the surface to be cleaned, (ii) positioned in use closer than the inlet to the surface to be cleaned, (iii) creating during operation a region between the body and the surface to be cleaned that has lower pressure than the ambient water pressure near the surface to be cleaned, and (iv) comprising a shaft laterally offset from the inlet and blades extending radially from the shaft, for pushing pool water laterally toward the inlet. 2. An automatic swimming pool cleaner according to claim 1, further comprising second means, configured for rotation about an axis generally perpendicular to the surface to be cleaned, for pushing pool water toward the inlet. 3. An automatic swimming pool cleaner according to claim 2 in which the first means and the second means are positioned on opposite sides of the inlet. 4. An automatic swimming pool cleaner according to claim 2 in which the first means is configured to rotate in a first direction and the second means is configured to rotate in a second direction opposite the first direction. 5. An automatic swimming pool cleaner according to claim 4 in which the second means comprises blades. 6. An automatic swimming pool cleaner according to claim 1 in which the first means comprises a wear surface configured to contact the surface to be cleaned. 7. An automatic swimming pool cleaner according to claim 1 in which the first means is at least partly recessed within the body. 8. An automatic swimming pool cleaner comprising: a. a body comprising (i) a water inlet for receiving debris-laden water of a swimming pool, (ii) a water outlet, and (iii) a fluid-powered motor through which the debris-laden water passes;b. at least one driven wheel or pulley;c. at least one undriven wheel having a circumferential groove having a width; andd. a continuous, one-piece, closed-loop track (i) configured to contact the at least one driven wheel or pulley and the at least one undriven wheel, (ii) having a width greater than the width of the circumferential groove, and (iii) having an external surface and an internal surface, the internal surface including at least one tooth received by the circumferential groove. 9. An automatic swimming pool cleaner according to claim 8 in which the undriven wheel has a width and the circumferential groove is positioned centrally along the width. 10. An automatic swimming pool cleaner according to claim 8 in which the internal surface includes a plurality of teeth, with adjacent teeth of the plurality of teeth being spaced longitudinally along the internal surface and not extending the width of the continuous, one-piece, closed-loop track. 11. An automatic swimming pool cleaner comprising a body having an interior and comprising: a. a lower section defining an inlet for receiving pool water;b, a fluid-powered motor positioned at least partly in the lower section in a flow path of debris-laden water received by the inlet;c. an upper section defining a water outlet and comprising means for connecting the body to a hose; andd. at least one hinge connecting the upper section to the lower section so that the upper section is moveable relative to the lower section to expose a downstream portion of the fluid-powered motor for removal of debris lodged therein. 12. An automatic swimming pool cleaner comprising: a. a driven wheel or pulley;b. a first gear connected to the driven wheel or pulley;c. a second gear;d. a third gear;e. a shaft (i) connecting the first gear to the driven wheel or pulley and (ii) defining a shaft axis;f. means, comprising a boss connected to the shaft, for moving the first gear in an arcuate path so as to engage either of the second and third gears, engagement with the second gear causing rotation of the driven wheel or pulley in a first direction and engagement with the third gear causing rotation of the driven wheel or pulley in a direction opposite the first direction, the boss being configured to pivot about an axis offset from the shaft axis. 13. An automatic swimming pool cleaner comprising: a. a fluid-powered motor;b. first and second driven wheels or pulleys;c. a first drive assembly connected to the fluid-powered motor and the first driven wheel or pulley and configured to rotate in each of a first direction and a second direction opposite the first direction;d. a second drive assembly connected to the fluid-powered motor and the second driven wheel or pulley and configured to rotate in each of the first and second directions; and in which, during operation, rotation direction of the second drive assembly is at least partially independent of rotation direction of the first drive assembly. 14. An automatic swimming pool cleaner according to claim 13 in which, during operation, rotation direction of the second drive assembly as a function of time may differ from rotation direction of the first drive assembly as a function of time.
