-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 releasing position, in which the closing member releases the liquid outlet;
-an actuating member, such as an actuating pedal, configured to be actuated by a user, such as with a foot of a user, the actuating member being movably mounted between a first actuating position and a second actuating position, the actuating member and the closure member being configured such that movement of the actuating member from the first actuating position to the second actuating position causes movement of the closure member from the release position to the closure position, and such that movement of the actuating member from the second actuating position to the first actuating 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 closure member and comprising a first indexing surface, a second indexing surface, which is further from the liquid outlet than the first indexing surface, and a connecting surface, which is inclined and which is disposed between the first and second indexing surfaces, the actuating portion being configured to abut against the first indexing surface when the actuating member occupies the first actuating position and advantageously hold the closure member in the release position and being configured to abut against the second indexing surface when the actuating member occupies the second actuating position and advantageously hold the closure member in the closure position, the actuating portion being configured to engage with the second indexing surface when the actuating member moves from the first actuating position towards the second actuating position, and the actuating portion being configured to engage with the second indexing surface when the actuating member moves from the first actuating position towards the second actuating position Sliding on the abutment surface and moving the closure member from the release position towards the closure position.
The presence of the connecting surface allows the closure member to be easily, effectively and reliably moved from the release position towards the closure position when the actuating member is moved from the first actuating position towards the second actuating 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 a reliable and optimal operation of the wet cleaning device, while ensuring an easy operation of the actuating member.
The cleaning head may also have one or more of the following features, used alone or in combination.
According to one embodiment of the invention, said actuating portion is configured to cooperate with an upper end portion of said closure member comprising said first indexing surface, said second indexing surface and said connecting surface.
According to an 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 connecting surface is more particularly inclined with respect to the direction of translation.
According to an embodiment of the invention, the second indexing surface is further away from the liquid outlet in the translation direction than the first indexing surface.
According to one embodiment of the invention, the mounting portion defines a mounting receptacle in which the closure member is mounted for translational movement.
According to one embodiment of the invention, the closing member extends along an extension axis, said extension axis being substantially parallel to said translation direction.
According to one embodiment of the invention, the actuating member is pivotably mounted relative to the cleaning liquid reservoir about a pivot axis.
According to one embodiment of the invention, the pivot axis extends transversely and for example perpendicularly to the direction of translation of the closure member.
According to one embodiment of the invention, the connecting surface is a cam surface. That is, a surface that allows for the conversion of a pivoting motion or a rotational motion into a translational motion. In the present case, the cam surface allows to convert a 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 an embodiment of the invention, the closure member comprises an axial projection arranged between the connecting surface and the second component surface and protruding with respect to the second component 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 undesired movements of the actuation member towards the first actuation position and, consequently, of the closure member towards the release position.
Advantageously, the top of the axial projection is further away from the liquid outlet in the direction of translation than the second component surface.
According to one embodiment of the invention, said end upper portion of said closure member further comprises said axial projection.
According to one embodiment of the invention, the first and second surfaces are substantially planar and substantially parallel with respect to each other.
According to one embodiment of the present invention, the wet cleaning apparatus includes:

-an upper annular sealing joint configured to effect sealing by axial contact between a first annular surface provided on the closure member and a second annular surface provided on the cleaning liquid reservoir 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 cooperate with a first annular surface provided on the closure member and a second annular surface provided on the cleaning liquid reservoir and effect a seal between the first and second annular surfaces.
This configuration of the upper annular sealing joint allows to significantly reduce 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 closed position and thus allows to facilitate the user's handling of the actuation member. In addition, this configuration of the upper annular sealing joint does not require the presence of an oversized biasing member to bias the closure member towards the release position and therefore reduces the manufacturing costs of the wet cleaning apparatus.
According to one embodiment of the invention, said upper annular sealing joint is axially offset with respect to said lower annular sealing joint along said axis of extension of said closure member.
According to one embodiment of the invention, said first and second annular surfaces extend facing each other.
According to one embodiment of the invention, said first and second annular surfaces extend substantially coaxially with respect to said axis of extension of said closure member.

According to one embodiment of the invention, said upper annular sealing joint comprises an annular sealing lip. These arrangements allow to eliminate any axial play of the closure member and therefore to ensure an optimal sealing at the upper annular sealing joint when the closure member occupies the closed position.
According to one embodiment of the invention, said annular sealing lip is oriented substantially parallel to said axis of extension of said closure member.
According to one embodiment of the invention, said 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 against the second annular surface when the closure member occupies the closed position.
According to an embodiment of the invention, the lower annular sealing joint is configured to effect sealing 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, the lower mounting portion being tubular and the lower part of the closure member being slidably mounted in the lower mounting portion.
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 engage 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 part of the closure member is slidable.
According to one embodiment of the invention, the upper mounting portion has a cross-section larger than a 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, in particular when the closure member is translationally movable.
According to an embodiment of the invention, said first and second division surfaces extend substantially perpendicular to said direction of translation of said closure member.
According to one embodiment of the invention, said upper annular sealing joint has an elastic deformation amplitude in the direction of translation equal to or greater than the height of said axial projection measured from said second surface of revolution. These arrangements allow to impart a satisfactory seal to the upper annular sealing joint over time, despite the fact that the upper annular sealing joint is compressed by the closure member when the actuation member moves from the second actuation position towards the first actuation position, and in particular when the actuation portion engages with the axial projection and biases the closure member towards the liquid outlet to a position which is located outside the closure position with respect to the release position.
According to one embodiment of the invention, the cleaning head comprises a main body comprising a sole plate provided with a sole plate lower surface and at least one suction channel opening into the sole plate lower surface, the wet cleaning device being configured to be fixed, for example in a removable manner, on the main body.
