Squeegee with selectable rotation mode

1 . A cleaning device comprising:

a handle graspable by a user and supporting a cleaning body arranged to wipe a surface, said handle comprising a longitudinal axis z, a distal end on which the cleaning body is supported, and a proximal end positioned opposite the distal end along the longitudinal axis z;

said cleaning body comprising a blade arranged to be in contact with said surface on a cleaning plane π, the cleaning plane π passing through a distal end of the blade and through the distal end of the handle;

wherein the cleaning device further comprises:

a first pivotal constraint arranged to allow a relative rotation α between said handle and said cleaning body about a first rotation axis x orthogonal to said cleaning plane π;

a second pivotal constraint arranged to allow a relative rotation β between said handle and said cleaning body about a second rotation axis y parallel to said cleaning plane π;

a first selection mechanism configured to alternatively arrange said first pivotal constraint in a free rotation mode, wherein said handle and said cleaning body can rotate freely with respect to each other with respect to said first rotation axis x, and in a locked rotation mode, wherein said handle and said cleaning body cannot rotate with respect to each other with respect to said first rotation axis x; said first selection mechanism is also configured to arrange said first pivotal constraint in a constrained rotation mode, wherein said relative rotation α has a maximum value equal to a first predetermined value a in the free rotation mode and equal to a second predetermined value in the constrained rotation mode, the second predetermined value being smaller than the first predetermined value,

a free rotation mode, wherein said handle and said cleaning body can rotate freely with respect to each other with respect to said second rotation axis y;

a locked rotation mode, wherein said handle and said cleaning body cannot rotate with respect to each other with respect to said second rotation axis y.

9 . A cleaning device comprising a handle graspable by a user and supporting a cleaning body arranged to wipe a surface, the handle comprising a longitudinal axis z, a distal end on which the cleaning body is supported, and a proximal end positioned opposite the distal end along the longitudinal axis z, said cleaning body comprising a blade arranged to be in contact with said surface on a cleaning plane π, the cleaning plane π passing through a distal end of the blade and through the distal end of the handle, wherein the cleaning device further comprises:
