A spill vacuum apparatus having a container having a cavity and a fluid inlet, the lower portion of the cavity including a fluid outlet closed by a check valve, the upper portion including a vacuum port and a fluid-level actuated release valve, the release valve cooperating with the upper portion to seal the cavity from the atmosphere until the release valve is actuated by a high fluid level reached within the lower portion by fluid volume, wherein coupling a vacuum source to the vacuum port depressurizes the cavity when the release and check valves are closed, and wherein when fluid is received in the lower portion through the inlet so as to reach the high fluid level, the release valve is actuated to unseal the cavity to the atmosphere, thereby releasing the weight of the fluid to actuate the check valve and release the fluid through the outlet.
