1. A method for detergent activation for a cleaning appliance having a rotatable non-ribbed drum for holding the textiles, the method comprising the following steps:
supplying a feed signal to an interface of a feed unit of the cleaning appliance, wherein the feed signal causes the cleaning liquid to be fed into a suds container of the cleaning appliance until a predetermined target fill level in the drum is reached;
supplying a motion signal to an interface of a drive of the cleaning appliance when the target fill level is reached, wherein the motion signal causes a rocking rhythm of the drum, wherein the rocking rhythm defines successive rotational motions of the drum at increasing rotational speeds without a complete revolution of the drum including a first rotational motion of the drum in a first direction until the drum has reached a first target rotational speed, and a second rotational motion of the drum in a second direction, opposite the first direction, until the drum has reached a second target rotational speed greater than the first target rotational speed; and
supplying a stop signal to the interface of the drive when a final rotational speed of the rocking rhythm is reached, wherein the stop signal causes the rotational motions of the drum to stop.
