Abstract
An automatic pool cleaner has a plurality of components, some of which have a density greater than water, giving the cleaner an overall negative buoyancy. The cleaner has a buoyant element which is adjustable in position relative to the center of gravity of the cleaner. Adjusting the position of the buoyant element changes the probable motion path of the cleaner on the pool floor and on the walls to allow the cleaner to execute a variety of motion paths to clean various parts of the pool. The adjustable element may be slidably positioned by a handle extending through a slot in the housing or be slidable on a slide band attached to the housing, which may be pivotable, translatable and rotatable, providing an additional range of position alternatives. A selected position is held by a detent or other holding mechanism. The adjustable element permits the cleaner to be adapted to clean various pool shapes and surfaces.
