ABSTRACT A method for collecting from a surface area crude oil or a similar highly viscous, tough and tacky material which covers the surface area as a layer, is characte- rised by consecutively separating volumes of the layer by means of a curtain of a fluid which under pressure is driven into the layer and has been heated to a tempera- ture capable of lowering the high viscosity of the ma- terial in the volume, and applying suction to the mate- rial in the volume thus made low-viscous, for removing this volume of material from the area. A suction nozzle for carrying out this method has a suction channel (1) which is connectible to a suc- tion conduit, a pressure fluid chamber (6) which has pressure fluid inlets and a first pressure fluid outlet (8, 9) surrounding the intake end of the suction channel.
