Abstract
A vacuum cleaner apparatus includes a housing, a motor disposed within the housing and having an output shaft, and a fan coupled to the output shaft for generating a vacuum airflow through an air intake port in the housing. A separator is operably coupled to the output shaft for separating dust and dirt particulates entrained in air ingested through the intake port. The separator has a body that defines a longitudinal axis of rotation and the motor drives the separator to rotate about the axis. The body includes a plurality of longitudinally extending vanes with each vane presenting a curved flow surface for increased particulate separation as the body rotates about the axis. The longitudinally extending vanes include beveled lower ends that reduce foaming. The separator also includes a plurality of secondary particle impacting vanes positioned in the bottom of the separator for trapping particulates within said separator.
