1. A laundry appliance, comprising:
a drum disposed within a cabinet and operably coupled to a motor that rotates the drum;
a blower that delivers process air through an airflow path that includes the drum; and
a controller communicatively coupled to a user interface, the motor, and the blower, wherein the controller is configured to selectively operate a foreign particulate cycle that includes a soft-start feature and an airflow speed routine and at least one of a speed modulating routine and a drum rotation routine that operate to agitate articles within the drum to separate foreign particulate from the articles, wherein the airflow speed routine operates independently of the speed modulating routine and the drum rotation routine, wherein the airflow speed routine directs the foreign particulate to a particulate filter, wherein the controller operates the airflow speed routine, the speed modulating routine, and the drum rotation routine based upon an identified type of foreign particulate, and wherein the controller includes a plurality of routines of the foreign particulate cycle that relate to the identity of the type of foreign particulate that is present on the articles.
