An assembly configured to be disposed within a well at an intersection of a parent bore of the well and a lateral bore of the well is provided. The assembly includes a junction having a mainbore leg and a lateral leg, as well as a passage in the mainbore leg configured to receive a flowing fluid. A port in the mainbore leg is in fluid communication with the passage such that the flowing fluid in the passage creates a suction at the port to draw debris in the well through the port and into the passage.
