1. A frame system for a modular construction of four different flat mop cleaning device frames comprising:
a first carrier plate having a first length in a longitudinal direction and a first width in a transverse direction;
a second carrier plate having a second length in the longitudinal direction which is different from the first length and a second width in the transverse direction which corresponds to the first width;
a third carrier plate having a third length in the longitudinal direction which differs from the first length and the second length and a third width in the transverse direction which corresponds to the first width and the second width;
a first clamp, wherein the first clamp forms longitudinal delimitations of the first, second and third carrier plates; and
a second clamp which forms longitudinal delimitations of the third carrier plate, wherein the second clamp has a greater length than the first clamp.
