a hinge comprising a first hinge portion and a second hinge portion which are movable relative to one another in rotation about a hinge axis parallel to the transverse direction, said second hinge portion being intended for connection to a gripping element,

a switching system, interposed between the cleaning head and the hinge, and adapted to move said hinge between a first position near the first surface and a second position near the second surface; and

first and second supports projecting upwardly from the cleaning head; the first hinge portion abuts against the first support when the hinge is in the first position, and the first hinge portion abuts against the second support when the hinge is in the second position,

wherein the hinge is rotatable about a pivot axis that is parallel to the transverse direction when moving between the first position and the second position.

10. Device according to claim 9 , wherein at the first position the second hinge portion is pivotable relative to the first hinge portion about the hinge axis.

11. Device according to claim 10 , wherein, in the first position, the first hinge portion abuts against the first support in alignment with the hinge axis, and the second hinge portion is spaced a distance from the cleaning head.

12. A device for cleaning a surface comprising:

a cleaning head that includes a first surface and a second surface which are both flat and are adapted to alternate in facing the surface to be cleaned, the first surface and the second surface having an angular offset relative to one another about a transverse direction;

the cleaning head further includes a first face opposite the first surface and a second face opposite the second surface, the first face and the second face having an angular offset relative to one another about the transverse direction;

a hinge connected to the cleaning head by a switching system, the hinge includes a first hinge portion and a second hinge portion which are movable relative to one another in rotation about a hinge axis parallel to the transverse direction, the second hinge portion being intended for connection to a gripping element; and

the switching system is interposed between the cleaning head and the hinge, and the switching system is configured to move the hinge between a first position near the first surface and a second position near the second surface.

13. The device of claim 12 , further comprising first and second supports, or first and second retention portions, projecting upwardly from the first face and the second face, respectively; the first hinge portion abuts against the first support or the first retention portion when the hinge is in the first position, and the first hinge portion abuts against the second support or the second retention portion when the hinge is in the second position.

14. The device of claim 13 , wherein, in the first position, the first hinge portion abuts against the first support or the first retention portion in alignment with the hinge axis, and the second hinge portion is spaced a distance from the cleaning head.

15. The device of claim 13 , wherein the first and second supports, or the first and second retention portions, project upwardly from the first face and the second face, respectively, substantially in alignment with a center of the first surface and a center of the second surface, respectively.
