The invention claimed is: 1. An automatic roller wringer for a mop, the automatic roller wringer comprising: an external casing comprising: a front, central hollow area, configured for being adapted on a bucket; and a rear area of the external casing on which is disposed a switch and a charging connection for connecting a battery charger; at least one motor configured to drive a plurality of gears incorporated inside the external casing, the at least one motor being fed from a circuit comprising at least one battery or accumulator accessible by an access door on the rear area of the external casing; two asymmetrical arms on each side of the hollow area operatively coupled to the at least one motor by the plurality of gears; and first and second transversal rollers arranged in the hollow area, the second transversal roller coupled to the asymmetrical arms and shifting until coinciding with the first transversal roller by means of two projecting lugs connected to the arms, the lugs resting on two parallel guides arranged on opposing inner faces on either side of the hollow area, the first transversal roller rotating but remaining fixed at a point in which it is located relative to the parallel guides. 2. The automatic roller wringer of claim 1, wherein the plurality of gears comprises: two main gears asymmetrically assembled on each side of the hollow area, engaging with the first roller, the main gears configured with an eccentric guide on the lower part of each one of them through which a pivot disposed on each of the movable arms pass, which arms generate the advance and pressure of the second roller on the mop and on the fixed, first roller which upwardly rotates along the entire length of the mop, the second roller returning to its standstill position. 3. The automatic roller wringer of claim 2, wherein a part of the arms which support the second transversal roller are provided with a spring on each one of the arms, starting up by a main switch, in collaboration with an external actuator generating the start up of an internal actuator, the motor maintaining rotation until a microswitch determines the stop of the motor and carries out the feeding of the circuit in the entire run. 4. The automatic roller wringer of claim 3, wherein one of the main gears is provided with a projection which operates the microswitch configured to switch off the motor. 5. The automatic roller wringer of claim 3, wherein a wringing process is generated with a single rotation of the main gears, the circuit thereby being open. 6. The automatic roller wringer of claim 3, wherein the battery is electrically coupled to a polarizing diode and a thermal element. 7. The automatic roller wringer of claim 1, wherein a part of the arms which support the second transversal roller are provided with a spring on each one of the arms, starting up by a main switch, in collaboration with an external actuator generating the start up of an internal actuator, the motor maintaining rotation until a microswitch determines the stop of the motor and carries out the feeding of the circuit in the entire run. 8.
