<p>A debris collecting tool (10) comprising a filter body (12) having an upstream end (13) and a downstream end (14), a first fluid passage (18) extending longitudinally between the upstream and downstream ends (13,14) of the filter body (12), and at least one second fluid passage (20) which connects the first fluid passage (18) with the exterior of the filter body (12). A filter (24) is located between the first fluid passage (18) and the at least one second fluid passage (20) and a flow controller (30) movable between a first position in which fluid is prevented from entering the at least one second fluid passage (20) from the exterior of the filter body (12), and a second position in which fluid is permitted to enter the at least one second fluid passage (20) from the exterior of the filter body (12). An agitator body (50) is attached to the upstream end (13) of the filter body (12).</p> |
