Abstract:
1. A portable device for dislodging particulate matter from a surface, the portable device comprising: a body segment that is movable with respect to a surface from which particulate matter is being dislodged; a high-pressure assembly operably connected to the body segment and generating a high-pressure fluid flow for being emitted toward the surface from which the particulate matter is being dislodged; and a nozzle assembly operatively connected to and receiving the fluid flow from the high-pressure airflow assembly, the nozzle assembly including multiple nozzles that are spaced from each other and configured to emit the fluid flow as a series of discrete pulses such that each of the multiple nozzles defines a blast diameter upon the surface from which the particulate matter is being dislodged, and wherein a cumulative blast pattern is defined by the combined blast diameters of the multiple nozzles, the cumulative blast pattern defining a coverage area that corresponds in size to an area value of a downwardly facing area of the nozzle assembly.
