A friction clutch drive is used to translate the oscillating angular movement of the oscillator in a submersible pool cleaner into a unidirectional periodic angular movement. A disc element affixed to a drive shaft of the oscillator is urged into contact with a second friction surface using a compression spring. The second disc is secured to a drum formation to which a gear to be driven is integrally formed so that rotational movement of the second disc causes rotational movement of the gear. To limit movement of the driven gear to one direction, a ratchet gear is affixed to the periphery of the drum and which engages a pawl to permit the single directional rotation of the drum and thus the driven gear.
