Abstract
A back flush filter system for a cleaning apparatus which includes a hollow filter member with a flow diffusing member inserted therein to cause the flow through the filter to be diffused into a substantially circumferential uniform flow passage through the entire area of the screen in both the filtering mode and the back flow mode of operation and including an atmospheric air vent to permit air entrapped within liquid flow system to escape and thus maintain a substantially air free liquid flow system.
