Abstract

A frame system for a modular construction of flat mop cleaning device frames including a first carrier plate having a first length in a longitudinal direction and a first width in a transverse direction, and a second carrier plate having a second length in the longitudinal direction different from the first length and a second width in the transverse direction corresponding to the first width. The frame system includes a third carrier plate having a third length in the longitudinal direction different from the first and second length, and a third width in the transverse direction corresponding to the first and second width. The frame system further includes a first clamp forming longitudinal delimitations of the first, second and third carrier plates and a second clamp forming longitudinal delimitations of the third carrier plate. The second clamp has a greater length than the first clamp.
