         7 . The cleaning unit according to  claim 1 , wherein the at least one locking member includes a connecting branch extending from the actuating member, and being elongate and elastically deformable, and a locking part extending from the connecting branch and configured to cooperate with the at least one locking element provided on the main body. 
     
     
         8 . The cleaning unit according to  claim 7 , wherein the connecting branch extends at least partially about the actuating member. 
     
     
         9 . The cleaning unit according to  claim 7 , wherein the locking part is formed at a distal end of the at least one locking member. 
     
     
         10 . The cleaning unit according to  claim 7 , wherein the connecting branch is connected to the actuating member at a connecting area, and the locking part and the connecting area are angularly offset relative to the axis of rotation. 
     
     
         11 . The cleaning unit according to  claim 7 , wherein the locking part has a first maximum width and the connecting branch has a second maximum width less than the first maximum width. 
     
     
         12 . The cleaning unit according to  claim 1 , wherein the at least one locking member comprises a first curved portion having a concavity oriented towards the inside of the closure cap, and a second curved portion having a concavity oriented towards the outside of the closure cap. 
     
     
         13 . The cleaning unit according to  claim 1 , wherein the at least one locking member comprises an overall S shape. 
     
     
         14 . The cleaning unit according to  claim 1 , wherein the at least one locking member is configured to protrude from an outer periphery of the cap body when the at least one locking member assumes the locking position. 
     
     
         15 . The cleaning unit according to  claim 1 , wherein the actuating member is movably mounted in rotation about an actuating axis substantially parallel to the axis of rotation of the rotating brush.
