ABSTRACT:
A self-cleaning vacuum head is disclosed which has the ability to discriminate between particles of different size, or the ability to separate fluids from particulate matter. The invention has two relatively moving surfaces which provide a changing locus of vacuum so that particles drawn against the surfaces are later separated therefrom. An oil spill clean-up system is also disclosed utilizing the self-cleaning vacuum head.
