  • connection sleeve In order to allow the connection sleeve to pivot to the left or to the right over a large amplitude of pivoting, it is known to position the articulation device at the rear of the main body of the vacuum cleaner nozzle, in order to limit the risk of conflict between the main body and the connection sleeve.
  • anti-lifting elements arranged at the rear of the main body.
  • Such anti-lifting elements may for example comprise casters arranged under the articulation device or under the connection sleeve and intended to roll on the surface to be cleaned when the vacuum cleaner nozzle is moved, or else one or more projections extending rearwardly and from a rear edge of the main body and provided with casters also intended to roll on the surface to be cleaned when of a movement of the vacuum cleaner nozzle.

  • the second side tank portion 21 comprises a second front tank portion 21.1, a second rear tank portion 21.2 located set back from the second front tank portion 21.1, and a second connecting surface 21.3 connecting the second portion of front tank 21.1 to the second portion of rear tank 21.2 so as to form a second rear lateral clearance 14.2 (see the Figure 15 ) located at the rear of the second connecting surface 21.3.
  • the first and second rear lateral clearances 14.1, 14.2 partly form the rear clearance 14.
  • each of the first and second connecting surfaces 19.3, 21.3 is concave seen in the median vertical longitudinal plane P of the vacuum cleaner nozzle 2, and comprises at least one upper surface portion which is extends substantially vertically.
  • each of the first and second rear tank portions 19.2, 21.2 has an upper face which is substantially flat and which is configured to extend substantially horizontally when the vacuum cleaner nozzle 2 rests on a horizontal surface.
  • the upper faces of the first and second rear tank portions 19.2, 21.2 extend in the same extension plane.
  • Each of the first and second rear tank portions 19.2, 21.2 can for example have a height of between 10 and 30 mm, and for example between 10 and 20 mm.
  • the cleaning liquid reservoir 17 further delimits an additional receiving housing 30 (see the Figure 15 ) which is configured to partly accommodate the articulation device 9 and which partly delimits the rear clearance 14.
  • the cleaning liquid tank 17 has a liquid storage chamber 27, and a liquid filling port 28 (see the Figure 15 ) opening into an upper part of the liquid storage chamber 27.
  • the liquid filling orifice 28 can for example be provided on an upper face of the cleaning liquid reservoir 17 or on a side face of the latter.
  • Such a liquid filling port 28 makes it possible to easily fill the liquid storage chamber 27 with a cleaning liquid, such as water.
  • the cleaning liquid reservoir 17 advantageously comprises a closing element 29 configured to removably close the liquid filling port 28.
  • the cleaning liquid tank 17 also has a liquid outlet 31 which is provided in a lower part of the cleaning liquid tank 17 and which is fluidly connected to the liquid storage chamber 27.
  • the wet cleaning device 15 further comprises a fluid distribution device 32 which is attached to the sole 4 and which is configured to be fluidly connected to the cleaning liquid reservoir 17 and to supply the mop 16 with cleaning liquid.
  • the fluid distribution device 32 comprises a distribution body 33 provided with an upper face in which the liquid outlet 31 is provided, and with a lower face in which is(are ) provided with one or more liquid flow orifice(s) 34 configured to supply cleaning liquid to the mop 16.
  • the or each liquid flow orifice 34 is configured to be located next to mop 16.
  • the wet cleaning device 15 comprises a shutter member 35 (see the Figure 13 ) which is movable between a closing position in which the closing member 35 closes the liquid outlet 31 so as to fluidically isolate the liquid storage chamber 27 and the liquid flow orifice(s) 34, and a release position in which the shutter member 35 releases the liquid outlet 31 so as to fluidly connect the liquid storage chamber 27 to the liquid flow orifice(s) 34, and therefore to ensure a supply of cleaning liquid to the mop 16.
  • the wet cleaning device 15 also comprises an actuator member 36, such as an actuation pedal, which is configured to be actuated by a user, for example with a user's foot, and which is mounted movable, and for example pivotally mounted, on an upper part of the cleaning liquid reservoir 17 between a first actuation position and a second actuation position.
  • the actuating member 36 and the shutter member 35 are configured such that a movement of the actuating member 36 from the first actuation position to the second actuation position results in a movement of the shutter member 35 from the release position to the shutter position and such that a movement of the actuating member 36 of the second actuation position to the first actuation position causes a movement of the shutter member 35 from the shutter position to the release position.
  • the main body 3 also comprises a covering cover 37 fixed to the sole 4 and configured to cover the central suction duct 7 and partly the cleaning liquid reservoir 17.
  • a covering cover 37 fixed to the sole 4 and configured to cover the central suction duct 7 and partly the cleaning liquid reservoir 17.
  • Such covering cover makes it possible in particular to protect the central suction duct 7 against external shocks during movements of the vacuum cleaner nozzle 2 on a surface to be cleaned.
  • the support force transmitted by the articulation device 9 to the main body 3 is applied to a rear part of the main body 3 and therefore above the sole 4.
  • the main body 3 is not likely to lift during use of the vacuum cleaner nozzle, which therefore ensures effective cleaning of the surface to be cleaned.
  • the presence of the rear clearance 14 allows pivoting to the left and to the right of the connection sleeve 8 with a large amplitude of pivoting, which gives increased maneuverability to the vacuum cleaner nozzle 2.
  • the location of the first and second pivot connections P1, P2 above a rear part of the main body 3 makes it possible to reduce the horizontal bulk of the vacuum cleaner nozzle 2.
  • the mop 16 could be mounted on a mop support vibrating relative to the main body 3.
  • the wet cleaning device 15 could comprise a mop support which extends at least partly under the sole 4 and which is fixed in such a manner removable to the sole 4, the mop 16 being fixed, for example in a removable manner, to the mop support, and the mop support being mounted movable in rotation relative to the main body 3 and around an axis of rotation substantially vertical when the main body 3 rests on a horizontal surface.
  • the vacuum cleaner nozzle 2 would comprise a rotational drive mechanism configured to rotate the mop support.
  • the cleaning liquid reservoir 17 could comprise a single connecting portion, and for example only the front connecting portion 22 or the rear connecting portion 23.
  • the articulation device 9 could mechanically connect the connection sleeve 8 to the cleaning liquid reservoir 17.
