1. A resilient universal nozzle for vacuum cleaning apparatus, said nozzle comprising an elongated tubular element with a coupling end which fits on a tubular pipe means in fluid communication with a source of sub-atmospheric pressure and a body portion terminating in a nozzle inlet end distal from said coupling end, said tubular element having a smooth bore, at least said body portion and nozzle inlet end comprising material which is deformable under manual pressure by the operator and having sufficient resiliency in operation and under suction pressures such that it returns to its original undeformed configuration upon release of said manual pressure, said resiliency preventing the collapse of said nozzle when subjected to material entraining suction pressures in either the deformed or undeformed condition, whereby the size and shape of at least the nozzle inlet end can be altered controllably to suit the operating requirements.
