Abstract
An debris-capturing apparatus having a fluid-pervious wall, an attachment portion attachable to the outflow port of a pressure-cleaner device, and a collapsible inflow tube that is substantially opened and made erect by the inflow of fluid but otherwise axially collapsed and thereby closed so as to block reverse flow of debris through the outflow port. The erected inflow tube preferably has cross-sectional flow areas along its entire length approximating the cross-sectional flow area of the outflow port. The debris-capturing apparatus is preferably integrally formed such that the inflow tube is a turned-in extension of the attachment portion.
