Abstract
A pool cleaning vehicle having a suction mouth placed at the belly of a housing. The pool cleaner is placed on two elongate rollers which allow the pool cleaner to move in opposite directions. The suction mouth is positioned between the two elongate rollers to reduce angular displacement when a roller wheel mounts a protrusion on uneven pool bed. A scrubber extends from within the mouth to sweep across the pool bed. The scrubber is pivoted to be able to swing when the pool cleaner changes direction.
