-a cleaning liquid reservoir located above the mop support and configured to supply cleaning liquid to a mop mounted on the mop support, the cleaning liquid reservoir comprising a liquid outlet provided in a lower portion of the cleaning liquid reservoir;
-a closing member movably mounted with respect to the cleaning liquid reservoir between a closing position, in which the closing member closes the liquid outlet, and a release position, in which the closing member releases the liquid outlet;
-an actuation member, such as an actuation pedal, configured to be actuated by a user, such as with a user's foot, the actuation member being movably mounted between a first actuation position and a second actuation position, the actuation member and the closure member being configured such that movement of the actuation member from the first actuation position to the second actuation position causes movement of the closure member from the release position to the closure position, and such that movement of the actuation member from the second actuation position to the first actuation position causes movement of the closure member from the closure position to the release position.
The actuating member comprises an actuating portion, such as an actuating finger, configured to cooperate with the closing member and comprising a first indexing surface, a second indexing surface and a connecting surface, the second indexing surface being further away from the liquid outlet than the first indexing surface, the connecting surface being inclined and the connecting surface being arranged between the first and second indexing surfaces, the actuating portion being configured to abut the first indexing surface when the actuating member occupies the first actuating position and to advantageously retain the closing member in the release position and to abut the second indexing surface when the actuating member occupies the second actuating position and to advantageously retain the closing member in the closing position, the actuating portion being configured to slide on the connecting surface and to move the closing member from the release position towards the closing position when the actuating member moves from the first actuating position towards the second actuating position.
The presence of the connecting surface allows easy, efficient and reliable movement of the closure member from the release position towards the closure position when the actuation member is moved from the first actuation position towards the second actuation position. In addition, the presence of the first and second indexing surfaces allows to stably hold the closure member in the release position and the closure position, respectively. These arrangements thus ensure reliable and optimal operation of the wet cleaning device, while at the same time ensuring easy operation of the actuating member.
The cleaning head may also have one or more of the following features, alone or in combination.
According to one embodiment of the invention, the actuating portion is configured to cooperate with an end upper portion of the closure member, the end upper portion of the closure member comprising the first indexing surface, the second indexing surface and the connecting surface.
According to one embodiment of the invention, the cleaning liquid reservoir comprises a mounting portion in which the closure member is mounted translatably movable in a translational direction. The connection surface is more particularly inclined with respect to the translation direction.

According to one embodiment of the invention, the connecting surface is a cam surface. That is, a surface that allows converting a pivoting or rotating motion into a translational motion. In the present case, the cam surface allows to convert the pivoting of the actuation member about a pivot axis into a translation of the closure member.
According to one embodiment of the invention, the actuating member is mounted on the cleaning liquid reservoir and, for example, on an upper portion of the cleaning liquid reservoir.
According to one embodiment of the invention, the closure member comprises an axial projection arranged between the connection surface and the second indexing surface and protruding with respect to the second indexing surface, the axial projection being configured to lock the actuation member in the second actuation position. The presence of such an axial projection allows to avoid an undesired movement of the actuation member towards the first actuation position and thus of the closure member towards the release position.
Advantageously, the top of the axial projection is further away from the liquid outlet in the translational direction than the second indexing surface.

-an upper annular sealing joint configured to achieve a seal between a first annular surface provided on the closure member and a second annular surface provided on the cleaning liquid reservoir by axial contact when the closure member occupies the closed position.
In other words, when the closure member occupies the closed position, the upper annular sealing joint is configured to axially mate with and seal between a first annular surface provided on the closure member and a second annular surface provided on the cleaning liquid reservoir.
This configuration of the upper annular sealing joint allows for a significant reduction in the force exerted by the upper annular sealing joint on the cleaning liquid reservoir when the closure member is moved between the release position and the closure position, and thus allows for convenient operation of the actuation member by a user. In addition, this configuration of the upper annular sealing joint eliminates the need for an oversized biasing member to bias the closure member toward the release position and thus reduces the manufacturing cost of the wet cleaning device.
According to one embodiment of the invention, the upper annular sealing joint is axially offset with respect to the lower annular sealing joint along the axis of extension of the closure member.
According to one embodiment of the invention, the first and second annular surfaces extend facing each other.

According to one embodiment of the invention, the annular sealing lip is oriented substantially parallel to the extension axis of the closure member.
According to one embodiment of the invention, the annular sealing lip has a substantially triangular cross section.
According to one embodiment of the invention, the upper annular sealing joint is mounted on the closure member and is configured to abut the second annular surface when the closure member occupies the closed position.
According to one embodiment of the invention, the lower annular sealing joint is configured to achieve a seal between an outer surface of the closure member and an inner surface provided on the cleaning liquid reservoir by radial contact.
According to one embodiment of the invention, the lower annular sealing joint is mounted in an annular groove provided on the outer surface of the closure member.
According to one embodiment of the invention, the mounting portion comprises a lower mounting portion, which is tubular and in which a lower portion of the closure member is slidably mounted.
According to one embodiment of the invention, the lower annular sealing joint is mounted on a lower portion of the closure member and is configured to radially cooperate with the inner surface of the lower mounting portion when the closure member occupies the release position.
According to one embodiment of the invention, the mounting portion comprises an upper mounting portion in which an upper portion of the closure member is slidable.
According to one embodiment of the invention, the upper mounting portion has a cross section that is larger than the cross section of the lower mounting portion.
According to one embodiment of the invention, the lower annular sealing joint is annular. This configuration of the lower annular sealing joint allows for control of the seal at the lower annular sealing joint, particularly when the closure member is translatable.
