  • Automatic pool cleaner
    Patent number: 4852211
    Abstract: Two suction disks are rotatingly mounted at the bottom of a housing divided into two filter chambers with a turbine chamber situated between them. A turbine disposed in the latter chamber can be connected by means of a riser and a suction line to a circulating pump. The turbine drives the suction disks in opposite directions of rotation by means of gearing. The turbine chamber communicates with each of the filter chambers through respective openings which can be closed by valve flaps. By means of a driving lever and a shifting bar, one valve flap is alternately opened and the other closed, whereby the suction effect is alternately changed over from one suction disk to the other.
