A brush for underwater cleaning of swimming pool edges and corners having a convex cylindrical bristle-mounting surface, bristles extending therefrom with distal ends which form a second convex cylindrical surface, and means for attachment of an elongated handle member. Preferred embodiments relate to certain curvature characteristics of the bristle and bristle-mounting surfaces, the 90- or near 90-degree arc of such surfaces, characteristics relating to suction through the brush member for removal of loosened dirt, and the rigidity of brush member, all of which serve to provide good cleaning of underwater edges and corners of varying profiles.
