The invention relates to a drive mechanism for a pool cleaner (101). Rotation from a turbine assembly (201) is transmitted to a pair of rear wheels. A first wheel (104.1) is forwardly driven. The second wheel (104.2) is switch between corresponding forward rotation and rearward rotation. An axle (109) of the first wheel (104.1) includes a coaxial shaft which rotatably supports a sleeve that carries the second wheel (104.2). The reverse transmission is effected by a double-sided dog clutch member (1 17) slidably between a pair of clutch gears (118, 119) freely rotatable ona rotating lay shaft (111). A first clutch gear (118) is connected for reverse rotation and a second clutch gear (119) for forward rotation of the sleeve carying the second wheel (104.2). A switching mechanism includes a movably mounted lever arm (122) engaging the double-sided clutch member (117) with a cam follower engaging a cam formation (116) carried on an independently supported control gear (115) in mesh with a worm gear (114) on the lay shaft (111). The lever arm includes a yoke (120) at one located in a central groove (121) around the double-sided dog clutch member (117). The other end of the lever is pivotably connected to the chassis (102). The turbine assembly (201) has a flow path from an inlet to an outlet (204) through one side of the housing and an eccentrically mounted rotor (203). The rotor (203) has a circular array of turbine blades supported between end plates (208) with each blade having an inner edge (210) that is spaced radially outwardly from an axis of the rotor (203) defining a central cavity between the blades.
