Abstract
A self-cleaning filter for a washing apparatus. Water entering a filter assembly travels along a spiral pathway that facilitates the separation of heavy solid debris from the water. A filter element prevents both light and heavy solid debris from entering a conduit leading to spray nozzles, thereby preventing clogging of the nozzles. In a filter cleaning operation, solid debris is removed from the filter assembly.
