Abstract: An apparatus for recovering floating materials, including a compartment with a weir for receiving the material to be recovered and a system for emptying the compartment. The weir forms at least one clean float at least partially immersed in the recovery compartment. The apparatus is remarkable in that the weir is connected to at least one float borne by a body of water outside the compartment so that it is sensitive both to changes of the level in the compartment and to the relative movement of the body of water outside. The connection between the weir and the outside float is advantageously provided by an assembly enabling relative motion between the weir and the outside float.
