Definitions

  • the invention relates to domestic vacuum cleaners, comprising steam cleaning functionality.
  • the invention relates to a canister steam and vacuum cleaner which is small and handy, being easy to carry and store, having at least one of width, length and height of the main body which is equal to or less than 300 mm, preferably equal to or less than 280 mm, more preferably equal to or less than 270 mm.
  • a cleaner with multiple functions.
  • a steam and vacuum cleaner i.e. a vacuum cleaner capable of drawing and filtering dirt and dust, while providing steam for removing dirt and grime embedded on the surfaces, is highly desirable.
  • the use of high temperature steam results in fact in deeper and more hygienic cleaning.
  • Some apparatuses such as upright vacuum cleaners, although having reduced width, are too heavy to lift, being suitable at most for cleaning floors, but not vertical surfaces, such as windows and walls.
  • US 2009/100631 discloses an upright vacuum cleaner with steam functionality, wherein the brush contains the vacuum means; said apparatus is thus only suitable for cleaning floors, while it is unhandy for cleaning vertical surfaces.
  • the same applies to the upright steam and vacuum cleaner disclosed in WO 2013/044196 which furthermore requires the inconvenient substitution of two different heads for using it alternatively in vacuum or steam cleaner configuration.
  • DE20202643 discloses a steam/vacuum cleaning apparatus that can blast high pressure steam onto a surface and is equipped with an air/water separation device.
  • canister vacuum cleaners Much handier than upright vacuum cleaners are canister vacuum cleaners.
