Abstract
Abstract A vacuum nozzle for cleaning underwater surfaces comprising a housing having a centrally-disposed intake channel opening into a hose coupling integally formed therewith. A plurality of brush bristles are secured in a U-shaped, resilient frame which is mounted in a seat or groove disposed in the bottom of the channel of the housing so as to extend outwardly therefrom. An elongated, rigid mounting member, disposed inside the channel, overlaps and engages the ends of the brush bristle mounting frame, and is fastened to a handle mounting member which engages the outside of the nozzle housing. The resilient mounting frame secures both the brush and the handle mounting member on the nozzle housing.
