- a closure member which extends along an axis of extension and which is mounted to move relative to the reservoir of cleaning liquid between a closure position in which the closure member closes the liquid outlet and a release position in which the closure member releases the liquid outlet,

- a lower annular seal which is mounted on a lower part of the shutter member and which is configured to prevent a flow of cleaning liquid through the liquid outlet when the shutter member is in the position shutter, and

- an upper annular seal which is mounted on an upper part of the closure member and which is therefore axially offset, along the axis of extension of the closure member, with respect to the seal lower annular seal.

The lower and upper annular seals are O-rings and are each configured to exert a radial force against an internal surface of a tubular mounting part provided on the cleaning liquid reservoir and in which is mounted movable in translation the member shutter.

Thus, when the closure member moves between the release position and the closure position, significant friction is generated between the lower and upper annular seals and the tubular mounting part. However, such friction makes it difficult to move the shutter member between the release position and the shutter position, and more particularly the operation by a user of an actuating member configured to move the release member. closure between the release position and the closure position, and on the other hand require the presence of an oversized biasing member to urge the closure member towards the release position.

According to the embodiment shown in the figures, the sole 6 comprises a lower sole face 7 configured to be oriented towards the surface to be cleaned, and a front suction channel 8 and a rear suction channel 9 each opening onto the lower sole face 7. The front suction channel 8 and the rear suction channel 9 communicate with the sleeve of connection 3 through in particular a connecting passage formed for example by a flexible conduit. Advantageously, each of the front and rear suction channels 8, 9 extends along a direction of extension D2 which extends transversely to the direction of movement D1 of the cleaning head 2. According to a variant embodiment not shown in the figures, the sole 6 could however be devoid of the rear suction channel 9 or be devoid of the front suction channel 8.

The cleaning head 2 further comprises a wet cleaning device 11 configured to be removably attached to the main body 4, and more particularly to the sole 6.

The wet cleaning device 11 comprises a mop holder 12 on which a mop is intended to be mounted. The mop holder 12 is configured to be arranged between the front suction channel 8 and the rear suction channel 9 when the wet mopping device 11 is attached to the main body 4.

According to a variant embodiment not shown in the figures, the cleaning head 2 could be devoid of suction means and therefore be configured to equip a wet cleaning device.

Of course, the present invention is in no way limited to the embodiment described and illustrated which has been given only by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
