The suction head is mounted movable relative to the vacuum cleaner housing between a retracted position in which the suction head is brought closer to a front edge of the vacuum cleaner housing, and an deployed position in which the suction head is spaced away from the front edge of the vacuum cleaner housing, the vacuum cleaner being configured such that a rearward tilting of the gripping handle and the vacuum cleaner housing, from a predetermined operating position of the vacuum cleaner and around of the axes of rotation of the first and second main wheels, causes a movement of the suction head towards the deployed position and such that a forward tilting of the gripping handle and the vacuum cleaner housing, in the direction of the predetermined operating position of the vacuum cleaner and around the axes of rotation of the first and second main wheels, causes the suction head to move towards the retracted position.

Such a configuration of the vacuum cleaner according to the present invention allows the latter, by tilting the gripping handle backwards and therefore moving the suction head into the deployed position, to reach areas inaccessible to the main body. (which has a height greater than that of the suction head since the main body is notably equipped with the suction motor), such as for example an area located under a piece of furniture.

Thus, the vacuum cleaner according to the present invention has high cleaning performance, while being simple in structure, economical and reliable.

The vacuum cleaner may also have one or more of the following characteristics, taken alone or in combination.

According to one embodiment of the invention, the first and second main wheels are arranged on either side of the vacuum cleaner housing. More precisely, the first and second main wheels are side wheels of the vacuum cleaner.

These arrangements give a significant deployment stroke to the suction head when the latter is moved from the retracted position to the deployed position, and therefore make it possible to thoroughly clean areas that are difficult to access.

According to one embodiment of the invention, the vacuum cleaner includes a locking device configured to occupy a locking configuration in which the locking device locks the vacuum head in the retracted position and prevents pivoting of the head suction head around the transverse hinge axis, and a release configuration in which the locking device releases the suction head and allows pivoting of the suction head around the transverse hinge axis. These provisions make it possible in particular to avoid a downward pivoting of the suction head when transporting the vacuum cleaner by a user, and therefore to avoid any damage to the suction head due to an impact of this last for example against the floor or a piece of furniture.

According to one embodiment of the invention, the locking device comprises a first locking element provided on the vacuum cleaner housing, and a second locking element provided on the suction head and configured to cooperate, for example by magnetization or snap-fit, with the first locking member when the suction head occupies the retracted position, so as to lock the suction head in the retracted position.

In other words, when the vacuum cleaner housing and the gripping handle are tilted backwards from the predetermined operating position, the at least one support part is configured to pivot the suction head, around the transverse hinge axis and at a distance from the vacuum cleaner housing, against the force exerted by the first locking element on the second locking element.

According to one embodiment of the invention, the second locking element is provided on an upper part of the suction head.

According to one embodiment of the invention, the at least one support part is provided on the fork.

According to one embodiment of the invention, the actuating member comprises two supporting parts which are arranged on either side of the locking device. These arrangements make it possible to better distribute the release force applied to the second locking element, and therefore to reduce, for the user, the effort to be applied on the gripping handle to involve the movement of the locking device of the configuration of lock to release configuration.

According to one embodiment of the invention, the fork comprises two fork arms mounted articulated on the vacuum cleaner housing via the rear pivot connection. Advantageously, each of the fork arms is provided with a respective support part.
