1. A particulate separating system for an appliance, the particulate separating system comprising:
a blower that directs process air through an airflow path that includes a processing space;
a particulate filter that is disposed within the airflow path and captures particulate material from the process air to define captured particulate on an upstream surface of the particulate filter; and
a fluid spray system having spray nozzles that deliver fluid to a surface of the particulate filter, wherein each of the spray nozzles defines a laminar flow of the fluid that directs the captured particulate away from the particulate filter, and wherein a top edge of the particulate filter is secured between the spray nozzles and a cover member for the airflow path.
