Abstract

A downhole tool for removing debris from fluid flowing through the downhole tool comprises a screen member in sliding engagement with an inner wall surface of the tool. As the screen member becomes blocked, it moves from a first or initial position to a second or actuated position which causes a pressure change detectable at the surface of the wellbore. The pressure change causes the debris blocking fluid flow through the screen member to fall off the screen member thereby allowing an increase in fluid flow through the screen member. As a result, the screen member returns to its initial position and fluid again flows through the screen member for capturing by the screen member.
