Abstract
A cleaner for swimming pools includes a housing having a pressure differential chamber with an opening defined by opposing walls and an oscillator pivotally mounted within the opening on a pivot axis extending between the walls. A seal is loosely fitted within a recess along a side of the oscillator for movement outwardly across a gap between the oscillator and the wall of the opening to close the gap when necessary for purposes of starting the oscillator and for opening the gap when required to allow grit, leaves and the like to pass through.
