Abstract
A compact assembly (40) with a turbine (20) fixed to a rotating drive shaft (22) with an extensible joint connected to small brush (38) by a shaft on the brush (36). The assembly (40) is inserted into a standard pool vacuum head (50) suction cavity (52) to provide a localized scrubbing action. The brush (38) is powered by the water pulled through the suction cavity (52) in the vacuum head (50) driving the turbine (20) causing rotation of the drive shaft (22) and brush shaft (36). The brush (38) is mounted to the end of the brush shaft (36). A spring (34) that is placed coaxial about the brush shaft (36) holds the brush (38) in contact with the surface (70) being scrubbed clean.
