1. A method for cleaning an interior of a pipe using a cleaning device, wherein the cleaning device has a tube and an advancing unit for moving the tube along a main axis (H) of the advancing unit, wherein the advancing unit has a drive which is frictionally connected to the tube and by which the tube is moved in an axial direction along the main axis (H), comprising the steps of:
axially moving the tube through the pipe along the main axis (H) while cleaning the interior of the pipe with a cleaning medium,
setting the advancing unit into a pendulum movement, which is a rotational movement with two end positions, between which the advancing unit is repeatedly moved back and forth, about the main axis (H) during the axially moving the tube, wherein the drive transmits the pendulum movement to the tube.
