Mop device with pedal squeezer, characterized by three pieces made of plastic, several iron tubes, and two springs. The first piece is basically a rectangular cube that has an oblique groove that goes down from a third of the upper side of a face, up to a third of its height (1), and from there horizontally to the other side in a symmetrical way, leaving it reduced in height throughout this area (2). The cube also has in its lower part two guides (3), one on each side, which have transverse reinforcers, which leave space to contain inside a cylindrical tube in the shape of "U", which protrudes in the front area at the same (4). In the lower rear area the cube retracts first obliquely and then horizontally (6). In this part presents a tongue (7), which is formed by continuing the face of the bottom of the cube. Also, in each of the two ends of this area, there are three sheets (8), which create two regions in which by means of holes the ends are inserted cylindrical tube cited above, which rises and rotates perpendicularly through this area said orifice, protruding from the hub, and constituting itself on the axis of rotation of the third piece (9). The second piece is constituted by a central plate that curves forming an "L" of more open angle (10), and two lateral plates integrated with the previous one, which have the same shape of the two internal faces and upper flange of the cube, reaching the horizontal part of the recess (11). This piece is coupled to the hub, assembled and being anchored by projections that exist in the flanges (12), which overlap the edges of the cube, and prevent their retraction. The central plate is drilled at determined distances (13). The side plates have ridges in the lower part and anterior vertical in the shape of "L" (14), and on each side of the squeezing plate come four parallel stiffeners that go obliquely to the bottom end (15). The upper end of the squeezing plate is curved downwards, and will have transverse reinforcers (16), with a hole so that a longitudinal, cylindrical iron tube of the same diameter as described above (17) is housed therein. The third piece is formed by two quadrangular plates (18), integrated in their sides to two crossbars in the shape of "H" (19), which protrude from said plates by one of their ends, until they join both forming an acute angle which ends in a cylindrical projection (20), with a hole in which the axis of rotation indicated above is inserted. The first of the plates is drilled at determined distances (21), and at the lower end will have an area that is not adhered to the crossbar (22). The top of this area of the plate is in the form of "L" (23). At the opposite end of this plate, and at the beginning of the adhesion zone to the crossbar once the free zone has been completed, there will be reinforcers with holes (24). In these two points the spar will contain cylindrical projections (25), equal to those of the angle, which will cross an iron tube with the same characteristics as that indicated in the second element passing behind the plate and through the holes of the reinforcers, until reach the opposite cylindrical projection. The other plate is of equal length but of smaller width, and it has for object to constitute itself in the pedal of the system. The top of this plate on the inner side is in the shape of "f", and on the outside it will be curved and will have transverse reinforcers with a hole (27). At this point the spar will also have a cylindrical projection that will be crossed by an iron tube with the same characteristics as indicated above, extending to the opposite protrusion behind the iron, passing through the holes of the reinforcers. This last protrusion is joined to the intermediate protrusion of the stringer of the squeezing plate by another spar (28), forming a triangle, which is reinforced with a triangular plate that joins this part to the joining spar forming a membrane with a finish on its part top in a "T" shape (29). All this element scales around the axis, at an approximate angle of about 30 degrees, finding a limit for the meeting of the two squeezing plates. A small protrusion (30) emerges from the middle of each connecting beam, into which one end of a spring (31) is inserted, the other end joining to a groove in the flange of the hub, keeping the third part lifted.
