A pig for use with a tubular bore wherein the pig is comprised of a body which supports a plurality of turbine blades wherein the blades mechanically break down and remove debris from the tubular bore. The blades have a profile which allows forward movement and rotation about a longitudinal axis when acted upon by a propulsion fluid traveling through the tubular. In an alternative embodiment the blades are mounted on a stabilizer body to allow simultaneous centralization and cleaning.
