Definitions

  • the present invention relates to the field of vacuum cleaners equipped with a suction nozzle, also called suction head, to suck dust and small-size waste present on a surface.
  • Vacuums equipped with a suction nozzle are well known on the market, they allow cleaning surfaces by suction for the evacuation of dust and small size waste based on them.
  • the surface to be vacuumed may for example be tiled, parquet, laminate, carpet or carpet.
