Abstract
A drain line cleaning apparatus is disclosed which includes a spin head, capable of high speed rotation. The spin head is attached to a spinner cap which carries a bit and one or more blade members which cut through roots and other residue deposited in drains. The spin head is powered by water jetted to notches formed on an inner surface of the spin head. The jetted water is also deflected by the notches to create thrust to force the drain line cleaning apparatus through the drain line.
