Abstract
A debris-capturing apparatus for a cleaner device having an outflow port through which debris-laden liquid flows. The debris-capturing apparatus has an entry annulus and a debris cavity to receive flow of debris-laden liquid. A collapsible elongate back-flow restrictor, which is substantially erect in the flow direction during inflow, has an annular proximal-end portion secured about the entry annulus and a free-end portion within the debris cavity. The free-end portion has at least one discontinuity along the length thereof to relieve resistance to debris-laden fluid flow into the cavity and to facilitate collapse of the restrictor for back-flow restriction.
