Tanker-type equipment for collecting wet material or dry material, wherein said equipment comprises: - a mobile vehicle comprising a frame on which a collection tank is installed, said collection tank comprising at least a first compartment for collecting said dry material or said wet material; - a vacuum assembly for generating a vacuum at least inside said first compartment; - a suction line through which said first compartment communicates with said vacuum assembly so that, following the activation of said vacuum assembly, an air flow coming from said first compartment and directed to said vacuum assembly is drawn through said suction line characterized in that said equipment comprises: - a washing assembly for dispersing water in said air flow coming from said first compartment so as to moisten any solid particles contained in said air flow, said washing assembly being activated at least during the collection of dry material; - a first cyclone filter arranged along said suction line to intercept said solid particles moistened by said water, wherein said first cyclone filter induces said air flow and said water dispersed therein in a whirling motion following which a wet mixture, formed by said water and said solid particles, is separated from said air flow, - a second cyclone filter operatively arranged along said suction line between said first cyclone and said first compartment to intercept a first fraction of solid particles contained in said air flow coming from said first compartment when said collected material is dry and to intercept a wet mixture formed by water and solid particles contained in said air flow when said collected material is wet. wherein said second cyclone filter comprises an inlet communicating with said first compartment through a first section of said suction line, a first outlet to let said first fraction of solid particles or said wet mixture separated from said air flow out, a second outlet to let said air flow deprived of said first fraction of solid particles or of said wet mixture out, wherein said first outlet communicates with a compartment of said tank, wherein said first cyclone filter comprises an inlet for said air flow communicating with said second outlet of said second cyclone filter, a first outlet communicating with a compartment (11,12) of said tank through a cyclone discharge valve and a second outlet communicating with said vacuum assembly, wherein said tank defines a second compartment, different from said first compartment, in which only wet material is collected, wherein said first outlet of said first cyclone communicates with said second compartment and wherein said first outlet of said second cyclone communicates with said first compartment. - a mobile vehicle comprising a frame on which a collection tank is installed, said collection tank comprising at least a first compartment for collecting said dry material or said wet material;
