Abstract
A fluid sprayer includes a rigid fluid conduit extending along a conduit axis between longitudinally opposed open conduit first and second ends. A spray nozzle having a fluid-expulsion bore is connected to the conduit second end such that the nozzle can pivot about a nozzle-pivot axis that extends orthogonally to the conduit axis and fluid introduced into the conduit first end is expelled through the fluid-expulsion bore. An attachment-mounting arm is connected to the fluid conduit for pivotal movement about an arm-pivot axis having a component of spatial extension orthogonal to the conduit axis and being longitudinally non-displaceable relative to the rigid fluid conduit. Moreover, the attachment-mounting arm is selectively lockable into a plurality of discrete angular positions relative to the conduit and configured to removably retain a surface-engaging attachment designed for engaging a surface to be cleaned.
