Abstract
Portable devices for dislodging and/or capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices include a body segment and a nose segment extending away therefrom. A high-pressure assembly generates a high-pressure airflow that is directed to a nozzle assembly in the nose segment. From the nozzle assembly, the high-pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface from which the particulate matter is being dislodged. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, is selected to impart the desired particulate matter dislodging characteristics to the device, and the device may incorporate a vacuum airflow to remove the particulate matter after such matter has been dislodged.
