Abstract
The invention concerns a pipe cleaning machine for rotating cleaning spirals of different diameters. To adapt the container for the cleaning spiral and the machine to cleaning spirals of different diameters with a minimum of accessories, the container for the cleaning spirals is made in a known manner in the form of a guide hose, but the inside diameter of the guide hose and of its coupling to the machine is equal to or greater than the inside diameter of the hollow shaft parts of the machine which receive the cleaning spirals and a collet for adapting the machine and the guide hose to different cleaning spiral diameters is removably mounted in the coupling.
