It significantly speeds up the process of separating the liquid from the solid.

A vacuum lowers the pressure on the filtrate side, increasing the pressure differential across the filter and so the flow rate (and often yielding a drier cake). It does not guarantee 100% purity and it is not used to separate two mixed liquids.
