  • the protective structure 32 delimits a central opening 34 which is large enough to allow the removal of the waste collection bowl 11 through the central opening 34.
  • the waste collection bowl 11 can be grasped and removed easily. of the vacuum cleaner housing 3 by the user through the central opening 22 delimited by the protective structure 32.
  • the figures 7a to 7d illustrate, according to four stages, dodging a frontal obstacle, such as a table leg presenting itself frontally to the suction assembly 1.
  • a frontal obstacle is an obstacle coming to meet and come into contact with the assembly suction 1 when the suction assembly 1 moves forward AV.
  • the suction assembly 1 moves forward AV.
  • An obstacle 30 stands in the path of the suction assembly 1 and in front of the first main wheel 23.
  • the suction assembly 1 continues its forward movement AV and comes into contact with the obstacle 30. More specifically, an inclined outer surface 35 of the structure protection 32 comes into contact with the obstacle 30 by interposing itself between the obstacle 30 and the first main wheel 23 thus preventing the obstacle 30 from colliding with the front of the first main wheel 23.
  • a third step represented in figure 7c the suction assembly 1 continues its forward movement AV, the inclined outer surface 35 slides over the obstacle 30. Thanks to the inclination of the inclined outer surface 35, at the same time as the set of suction 1 moves forward AV, suction assembly 1 moves laterally L.
  • the suction assembly 1 continues its forward movement AV, the inclined outer surface 35 is clear of the obstacle 30.
  • the suction assembly 1 continues to slide over the obstacle 30 by contact between the obstacle 30 and the first outer hub surface 28a of the first fixed wheel hub 28.
  • the first outer hub surface 28a of the first fixed wheel hub 28 is located in top view of the suction assembly 1 substantially in the extension of the inclined outer surface 35.
  • the sliding relative to the obstacle 30 on the first outer surface of the hub 28a has the effect, on the one hand, of continuing to move the suction assembly 1 laterally as it moves forwards AV and, on the other part to remove the obstacle 30 of the first first main wheel 23 to prevent the obstacle 30 from colliding with the first main wheel 23, in particular a rear part of the first main wheel 23.
  • Obstacle dodging according to the above four steps is obtained by a combined effect of the protective structure 32 and the first and second outer hub surfaces 28a, 29a of the first and second fixed wheel hubs 28, 29 in the form spherical caps.
  • the protection structure 32 comprises also an inclined outer surface 36 which is located on the side of the second main wheel 24 and which is configured to come into contact with an obstacle 30 located on the side of the second main wheel 24, so as to prevent the obstacle from coming hit the front of the second main wheel 24.
  • the first outer hub surface 28a of the first fixed wheel hub 28 could directly come into contact with the obstacle 30, that is to say without the latter coming prior to contact with the protective structure 32.
  • the spherical cap shape of the first outer surface of hub 28a associated with first and second main wheels 23, 24 of the omnidirectional type, allows, when the obstacle 30 encounters the first outer hub surface 28a, a lateral rolling movement of the suction assembly 1 which is continuous and progressive as the forward movement AV of the suction assembly 1, which finally allows the suction assembly 1 to emerge more easily from the obstacle encountered.
  • the first and second main wheels could respectively have a first outer wheel surface and a second outer wheel surface which are each in the shape of a spherical cap and which contribute to forming the shaped assembly globally spherical.
