  • Vacuum cleaner head
    Patent number: 9788696
    Abstract: Vacuum cleaner head (100) comprising a bottom sole (10) and wheels (30, 35) defining the ground clearance of the bottom sole and comprising at least one suction duct (20) open toward the ground and converging from an outer edge of the bottom sole (10) toward a suction orifice (15) connected to the vacuum cleaner, characterized in that the suction head comprises a sealing skirt (40) arranged around the periphery of the bottom sole (10), and in that the sealing skirt (40) has at least one opening (45) positioned opposite said at least one suction duct (20).

  • Cyclonic separation device with acceleration ramp
    Patent number: 8806707
    Abstract: 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.
