Abstract
A vacuum cleaner hose comprises alternating height corrugations which break up airflow and reduce or eliminate whistle during vacuum cleaner operation. The hose likewise provides a high degree of flexibility, crush and kink resistance, and returnability back to its original shape. The hose may be formed of a single non-reinforced member by an extrusion blow-molding process. In one embodiment, the widths of the corrugations alternate with the heights.
