ABSTRACT:
A universal nozzle which has a tubular body with a coupling end that fits on the hose of a vacuum cleaner and an inlet end distal from the coupling end. The nozzle has a smooth bore and is made from a resilient material which is manually deformable such that the inlet opening and configuration can be altered by the operator to suit operating conditions. The nuzzle material has sufficient resiliency to regain its original configuration after being manually deformed and to resist collapse because of suction pressures whether in a deformed or undeformed condition. A synthetic organic compound such as plastic resin or a natural material alloyed with fillers or reinforcing agents to produce a formulation having a Shore-A hardness of 60-95, preferably 80.+-.10, is a particularly suitable nozzle material.
