Abstract: The hose, which is particularly adapted for use with an electrically-driven vacuum cleaning apparatus, comprises a substantially air-tight, flexible tube which is pneumatically coupled between the vacuum pump and the suction head. The suction hose comprises one or more elongated strips which is or are helically wound into tubular form. In a pair of parallelly placed strips, the strip margin of the first strip is secured to an adjacent margin of the second strip at adjoining convolutions of the strips. Electrical conductors are carried by the strips within helically extending cavities formed at the edges or margins of each of the strips and are a portion of that means which electrically couples the cleaning brush to the electrical power supply.
