Abstract
A replaceable bristle ring for removable attachment to a swimming pool cleaner, such bristle ring having bristles secured along it and projecting downwardly to terminate in bristle ends adapted to support the pool cleaner on a surface to be cleaned and means facilitating attachment with respect to the pool cleaner housing. A preponderance of the bristles are preferably inclined along lines which are skew lines with respect to the axis of the ring, such that vibration causes movement of the pool cleaner along a swimming pool bottom surface. A preferred replaceable ring has an annular surface with features for interengagement with another bristle ring.
