  • the suction cavity 31 is elongated and extends along a direction of extension which is transverse to the direction of movement of the main body 2.
  • the locking device 34 makes it possible in particular to be able to transport the vacuum cleaner 1, when it occupies the storage position, without risking a downward tilting of the suction head 9.
  • the locking device 34 comprises a first locking element 35 which is provided on the vacuum cleaner housing 3, and a second locking element 36 which is provided on an upper part of the suction head 9 and which is therefore located in front of the transverse hinge axis A.
  • the second locking element 36 is configured to cooperate, for example by magnetization or snap-fastening, with the first locking element 35 when the suction head 9 occupies the retracted position, so as to lock the suction head 9 in the retracted position.
  • the vacuum cleaner 1 advantageously comprises an actuating member configured to automatically move the locking device 34 into the release configuration when the vacuum cleaner housing 3 and grip handle 15 are tilted rearward from the predetermined operating position.
  • the actuating member comprises two support parts 38, such as support shoes, provided respectively on the fork arms 33 and located at the rear of the axle of transverse articulation A.
  • the support parts 38 are more particularly configured to rest on the ground when the vacuum cleaner housing 3 and the gripping handle 15 are tilted backwards, from the predetermined operating position, and to exert on the second element 36 a releasing force such that the resultant of the forces exerted on the second locking element 36 is greater than and opposite to the locking force exerted by the first locking element 35 on the second locking element 36.
  • the support parts 38 when the vacuum cleaner housing 3 and the handle 15 are swung backwards from the predetermined operating position, the support parts 38 are configured to cause the suction head 9 to pivot around the transverse axis of articulation A and at a distance from the vacuum cleaner housing 3, against the force exerted by the first locking element 35 on the second locking element 36.
  • Such a configuration of the vacuum cleaner 1 ensures movement automatic device locking 34 in the release configuration when the handle 15 tilts backwards, and therefore allows the suction head 9 to move between the retracted position and the extended position.
  • the vacuum cleaner 1 is configured such that, during the first stroke portion, the entire suction head 9 is raised relative to the surface to be cleaned.
