An apparatus for removal of material by suction, comprising, supported by the chassis of a truck, a partial vacuum unit for a collection tank, to which aspirated material is conveyed. The tank is fitted on an unloading device suitable to lift on one side the tank in order to empty by gravity the material accumulated therein. The unloading device comprises a frame rotatably coupled to the chassis by interposing a rotatable center bearing, provided with an actuation for actuating the rotation of the frame with-respect to the chassis. The frame has a base for connection to the center bearing, and a supporting structure for the tank is associated with the base. The structure is adapted for multiple movements for positioning and unloading the tank outside of the truck footprint.
