Abstract
Abstract An oil recovery mop has a floating carriage, a handle, and a number of oil-absorbing pads or squares suspended from the carriage. The carriage has a pair of tubular pontoons that support a crossbar at a clearance over the surface of the water, and the pads are removably attached to spring clips on the crossbar. When the oil mop is pushed out, one side of each pad faces the surface to absorb spilled oil. When the oil mop is pulled in, the pads reverse themselves and the other side faces down to absorb oil.
