1. In debris-capturing apparatus of the type including (a) a fluid-pervious wall forming a cavity, (b) an attachment portion that forms an inflow opening and has an annular lowermost edge, the attachment portion being attachable near its lowermost edge to the outflow port of a pressure-cleaner device, and (c) inside the cavity a collapsible inflow tube that is substantially opened by inflow of fluid but is otherwise closed to block reverse flow of debris through the outflow port, the improvement wherein:

  • the inflow tube has an annular proximal edge secured to the attachment portion at and around the annular lowermost edge thereof; and

    the inflow tube is of a material chosen such that the inflow tube is made substantially erect along a flow axis by inflow of fluid but otherwise collapses axially to block reverse flow of debris.
