ABSTRACT:
A propelled floating swimming pool skimmer having a plurality of angularly related channels with gate means in each of the channels permitting ingress of water and floating leaves and debris into a central area of the body of the device. Nozzles around the periphery of the body propel the unit in desired directions which change automatically in a desired sequence so the unit will cover the entire pool surface. The entrapped leaves and debris are forced downwardly in a spiral path by downwardly-directed jets into a mesh bag in which the leaves and debris may be removed from the pool and, in another form, the leaves and the debris are drawn downwardly through a mesh basket and then through a flexible conduit to the swimming pool vacuum system. Propulsion is accomplished by water under pressure furnished through a flexible conduit to the unit from a suitable source.
