ABSTRACT:
A hole cleaning device 100 includes a housing having a porous region to communicate cuttings from a bore hole to the interior of the housing. A Venturi-effect pump creates a suction to draw cuttings from the hole into the housing. An outlet pipe coupled to the Venturi pump transports the cuttings out of the housing.
