Think of it as an air compressor in reverse.. your engine makes plenty of vacuum at idle, but when you open the throttle the vacuum drops considerably. The vacuum reservoir, ball, bottle, tank, or thingie as it's often called keeps your vacuum operated accessories supplied with plenty of vacuum. Some relocate it to the engine compartment when they modify their bumpers.
