1. A tool, comprising:
a body defining a bore axially therein;
a cleaning system comprising nozzles coupled to the body and configured to spray a fluid onto an interior of a wellsite component; and
an inspection system coupled to the body, wherein the inspection system is configured to capture images, video, or both of the wellsite component that are to be used to determine whether the wellsite component is clean after being sprayed with the fluid, wherein the inspection system comprises a piston that separates the bore into a lower piston chamber and an upper piston chamber, and wherein body is configured to deliver the fluid into the nozzles and into the lower piston chamber but not the upper piston chamber, so as to generate a pressure differential across the piston.
