The invention concerns a cleaning implement (10), which comprises a mop body (11), to which is articulated an arm (12), with which the mop body (11) can be moved when cleaning. The mop body (11) comprises a rocking body (14), which is articulated to it and which is articulated to turn around a geometric axis (X₁). The rocking body (14) comprises a first rocking body-half (A₁) and attaching means (16a₁, 16a₂). The rocking body (14) also comprises a second rocking body-half (A₂) and attaching means (17a₁, 17a₂), whereby the rocking body (14) can be placed in such a position, where a gap (K) is formed in between the rocking body (14) and the mop body (11), into which gap the cleaning device (M) can be placed. The rocking body (14) can be turned to an end position, in which the gap (K) is either closed or open. The attaching means (16a₁, 16a₂) bring about the gap's (K) open position and the second attaching means (17a₁, 17a₂) bring about the gap's (K) closed position, in which the rocking body (14) with its body-half (A₂) will press the cleaning device (M) against the mop body (11).
