A sewer line root cleaning and repair system includes a root cleaner having a first body and a second body connected by a flexible connector. A flexible rotating member extending from a pneumatic motor in the first body extends through the flexible connector and the second body. The flexible rotating member terminates beyond the second body in a series of bristles. As the root cleaner moves through a sewer line a set of wheels on the first body extends outward, centering the first body in the sewer line as the bristles spin at high RPM centering the second body in the sewer line and scouring the sewer line free of roots including small root hairs. Afterward, a coating sprayer is inserted into the sewer line, connected to a coating supply and air supply, and the coating is sprayed under pressure to line the inner surface of the sewer line.
