1. A method of operating a waste collection unit including a waste canister, a manifold receiver, a suction pump, a vacuum regulator, a vacuum sensor, a display panel, a light assembly separate from the display panel, and a processor, the method comprising:
receiving a manifold within the manifold receiver to establish fluid communication between the manifold and the waste canister;
drawing with the suction pump a vacuum on the waste canister;
measuring with the vacuum sensor a vacuum level of the vacuum drawn on the waste canister;
receiving with the processor a vacuum level signal from the vacuum sensor that is indicative of the measured vacuum level; and
operating with the processor the light assembly positioned adjacent the manifold receiver to selectively emit light of a color based on the measured vacuum level.
