摘要： A vacuum cleaner assembly comprising a body, a motor disposed within the body and having an output shaft for rotating about axis, a fan coupled to the output shaft for generating a vacuum airflow through an air intake port in the body, and a separator coupled to the output shaft. The separator includes a cup shaped body and a flange extending radially from the open top to an outer periphery. The separator includes a spider, integrated therewithin, having a hub portion surrounding the shaft, and a plurality of helical blades integral with and extending radially from the hub portion to the vanes and integral with the wall. The separator is one piece molded component that may provide for better turbulence characteristics during suction of the air, increase the centrifugal forces to separate the dust and debris from the air flow.
