ABSTRACT:
A brush roll assembly for an upright vacuum cleaner having mounting blocks at each end to support the brush at different levels, to account for wear, depending on the selected angular orientation of such blocks. The blocks, while of different size to prevent improper installation end-for-end, are relatively large for convenience and performance and are configured to avoid obstruction of edgewise air flow and to avoid improper installation in an angular sense.
