  • Such a vacuum cleaner has a dust collecting device which has a suction opening.
  • a suction brush is connected to the suction opening.
  • the suction port is formed so that the air enters the dust collecting device substantially tangentially.
  • It has a centrifugal separator with a cylindrical or conical chamber. Air is drawn into the dust collector via an outlet. This air is caused to rotate by the tangentially formed suction opening and the shape of the dust collecting device. Centrifugal forces act on the particles in the flow, causing the particles to move radially outward. The particles are thrown to the outer wall of the separation chamber.
  • the present invention has the object to provide a dust collection device by means of which an improved separation of particles from the air stream is to be achieved.
  • the dust collecting device comprises a housing with a suction opening and an outlet. Through the suction opening a laden with particles, especially dirt particles air stream is sucked into the housing. Through the outlet of the air flow leaves the housing, at least with reduced particle density.
