Abstract: A mop system includes a flat mop holder to hold a mop cover in a first state and to release the mop cover in a second state, and which comprises an actuating kinematic system for causing a change from the first state to the second state. A mop handle is connected at a first end to the flat mop holder, and an actuating member is arranged opposite to the first end on the mop handle. At least one cable pull is adapted and arranged to transmit an activating force and/or movement from the actuating member to the actuating kinematic system. A plurality of mop handle sections are telescopically adjustable relative to one another, wherein the cable pull includes a length compensation device to variably adjust the cable pull corresponding to a telescopic position of the mop handle sections.

Abstract: In a flat mop cover with an active side to be directed onto a surface to be cleaned and opposite thereto a rear side, transverse edges opposite one another and longitudinal edges opposite one another, wherein the longitudinal edges are longer than the transverse edges and wherein the flat mop cover has on the rear side at least two pockets opposite one another in the transverse direction for receiving a flat mop holder, which extend along the opposite longitudinal edges, it is provided that at least one of the pockets is divided by at least one bar into at least two sections, wherein the bar is adapted and arranged for fixing a predetermined position of the flat mop cover on the flat mop holder.
