Abstract (en)
1. Swimming-pool cleaner for filtering the swimming-pool water and for cleaning the swimming-pool bottom with an electric-motor-driven pump which draws in swimming-pool water through a suction device (15), leads said water through a filter (10) and then pumps it back again into the swimming-pool whereby the suction device, the filter, the motor (1, 2) and the pump are combined to form a unit whose displacement is so great that in normal operation the cleaner, when immersed in the swimming-pool water, projects out of the water only with a part of the suction device so that floating dirt particles are drawn in, wherein the motor (1, 2) is in the form of an induction motor with two-phase low-voltage winding (31, 34) having two coil sets whereby the first winding (31) is supplied with low voltage by a first transformer (30) and the second winding (34) is supplied by a second transformer (32) which in turn is supplied from the mains through the intermediary of a capacitor (33).
