Abstract
A down-hole tool is described for collecting loose debris particles in a well bore. The tool has a body connectable in a work string for actively diverting well fluid through the tool body with at least some of the diverted well fluid being filtered as it passes through the tool by a filter. In a preferred embodiment the tool also comprises a cleaning member, such as a wiper for wiping the casing or liner wall of the well and a trap for trapping filtered debris up stream of the filter.
