Abstract
A method and apparatus for removing debris from a wellbore using a cleaning tool. The tool may comprise an inner mandrel and a cup member coupled to the inner mandrel. The cup member is moveable between a collapsed position where fluid may flow across the exterior of the cup member, and an extended position where fluid is diverted into a flow path disposed between the inner mandrel and the cup member. The fluid is diverted through a filter member that is coupled to the inner mandrel below the cup member.
