Abstract

A brush roller assembly for a vacuum cleaner includes a rotatable spindle having a longitudinal axis, a first end, a second end and a central portion. A first airflow enhancing device (“AED”) is positioned, by being molded onto or operationally attached to, the first end of the rotatable spindle. The first AED includes a central portion, which is positioned substantially perpendicular to the longitudinal axis of the rotatable spindle when the first AED is positioned on the first end of the rotatable spindle. The first AED includes at least one fan blade projection outwardly extending from the periphery of the central portion of the first AED. The fan blade projection facilitates the movement of debris directly or indirectly from the first end of the rotatable spindle toward the central portion of the rotatable spindle. A second AED device may be positioned on the second end of the rotatable spindle, wherein the second AED has similar structure to and attaches in similar fashion as the first AED. In one embodiment, the housing has a hole in the bottom to enable air to enter the housing, travel down the longitudinal axis and towards the central portion of the rotatable spindle. In another embodiment, the housing may have openings in the sidewalls that promote airflow directly from the outside of the housing to the ends of the rotatable spindle. In yet another embodiment, a pressurized fan is attached to the housing or the rotatable spindle to increase forced airflow.
