A system and an apparatus for positioning a plurality of flexible cleaning lances includes a frame removably fastened parallel a tube sheet of a heat exchanger. The apparatus includes a smart lance tractor drive for advancing and retracting one or more lance hoses through one or more lance guide tubes into tubes penetrating through the heat exchanger tube sheet, a controller, one or more AC induction sensors on the tubes operable to sense holes in the tube sheet, and a tumble box connected to the controller operable to generate electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The tractor drive includes sensors for detection of mismatch between expected and actual lance positions and automated drive reversal operation to remove blockages within tubes being cleaned.
