1. A nozzle monitoring system for a sprayer system of a work vehicle comprising:
a first sensor configured to generate signals associated with vibrations of a first nozzle apparatus on the work vehicle that disperses a primary fluid from the sprayer system during operation; and
a controller having a processor receiving the signals generated by the first sensor and having a memory coupled to the processor and storing instructions, the processor executing the stored instructions to:
convert the vibrations into a frequency domain representation;
generate an image from the frequency domain representation;
execute image recognition to classify the image with regard to a clog condition;
generate, based on the clog condition of the classified image, a clog condition probability;
generate, based on the clog condition probability, a cleaning event command; and
initiate, based on the cleaning event command, a cleaning event of the first nozzle apparatus.
