  • the present invention aims to remedy these drawbacks.
  • the technical problem underlying the invention consists in particular of providing a vacuum cleaner nozzle which is simple and economical in structure, while reducing the noise pollution generated by the vacuum cleaner nozzle and while guaranteeing protection of the floors to be cleaned. .
  • the rear anti-tilt stop is located at least partly at the rear of a vertical plane containing the transverse pivot axis when the nozzle rests on a horizontal surface, that is to say at least partly behind the transverse pivot axis.
