A self-propelled swimming pool cleaner which randomly covers the bottom of the pool. Water pumped from the bottom of the unit filters dirt carried thereby, then uses the pumped water to propel the device either forward to backward. A pivoted front axle causes the path of the unit to vary when changing from forward to backward so that the unit randomly covers the entire pool bottom. Spring loaded doors may be provided to allow water to exit when the unit is lifted out of the pool. A sealed motor unit has a metal portion to transfer heat from the motor.

Dispositif autopropulsé (10) conçu pour se déplacer de façon non déterminée au fond d'une piscine afin de nettoyer cette dernière. La partie inférieure de ce dispositif (10) filtre les impuretés contenues dans l'eau pompée qui, à son tour, permet de propulser le dispositif (10) soit vers l'avant, soit vers l'arrière. Un essieu avant rotatif (22) provoque la modification de la trajectoire du dispositif (10) au moment du changement de l'avant vers l'arrière, de sorte que ce dispositif (10) couvre de façon non sélective la totalité du fond de la piscine. Des volets optionnels (32) chargés par ressort peuvent servir à évacuer l'eau quand on sort le dispositif (10) de la piscine. Un moteur étanche (50) possède une partie métallique (56) servant d'élément de transfert thermique.
