A floating retriever for retrieving, for example, spilled oil or other liquid substances on the top of water having a central liquid collection chamber with a vacuum or suction pick-up for delivery of the pollutants to a mother vessel which controls the retriever by means of a boom structure. The retriever has a large surrounding circular float with intake ports with "V" shaped lateral screws to bring the retrieved liquid to the collection chamber. The device includes an inverted-dome, water well with limited openings underneath the collection chamber for stability, as well as radially positioned, selectively controlled, out-rigger screws including an auxiliary tow, for drawing the oil to the intake ports and providing for propulsion and guidance. The ports have inclined stepped bottom surfaces with discharge holes with a lower paddle wheel drive to initially enhance oil/water separation, as well as air jets or sprays for producing a suction effect in the intakes.
