A cyclonic separation device for dust and debris in vacuum cleaners, comprising a roughly cylindrical interior cyclonic chamber connected to an air intake, as well as a separator filter located in the central part of the interior chamber, comprising a tube segment to direct airflow to the air intake with this tube segment located around the roughly cylindrical interior cyclonic chamber, from a starting point to an end point near the air intake, with the cross-section of this tube segment near the end point being smaller than that near the starting point in order to form an acceleration ramp for the airflow between these two points.
