Abstract: An industrial vacuum cleaner, having a structure in the form of a trolley with a platform (1) on wheels (2) supporting a base (3) on which is seated an electric motor (4) connected to a radial compressor or vacuum pump (5). Two horizontal tubes (16) are connected to the front of the platform (1) and joined by two crossbars (17). At the extremities of the two horizontal tubes (16) there are casters (38). Both crossbars (17) are connected to two vertical tubes (18 and 19) of the same height, with U-shaped sockets (20 and 21) at the top end. These U-sockets are provided for slotting in segments of coaxial axle pins (22 and 23) which are placed on diametrically opposite sides of the drum (9). There are also handles (24) on either side of the drum.
