Abstract: The present invention is directed to a hydroblasting system comprising a head assembly connected with some conveyance, whether now known or hereafter developed. Such head assembly may comprise, for instance, biasing elements configured to provide such head assembly with a floating functionality stemming from, for instance, the creation of an independent suspension, thereby enabling such head assembly to traverse irregular topographies. Further embodiments of such a head assembly may be configured to enable the same to be used on work surfaces such as a ceiling or wall, via a pneumatic assembly configured to apply force to such head assembly. Such a head assembly may further comprise a rotating manifold configured to supply the applicator thereof with high pressure fluid, during angular misalignment between the fluid source and the applicator. Further embodiments may use sensors and computing systems to allow for the autonomous movement of such head assembly and/or conveyance.
