An attachment for use with automated pool sweeper systems attaches coaxially to the sweep hoses of such system and is carried thereby over the walls and floor of a pool to brush and buff these surfaces. The attachment is a tubular member of a porous foam-like material that is resistant to deterioration in chlorinated water and is resistant to shedding due to wear. The attachment may be snugly secured between wear rings on the hose and may be further secured by an elastomeric member encircling the attachment and the hose.
