Is it expected that a vacuum will be used for liposuction?

Liposuction is done with a vacuum type system that allows the fat to be sucked  into a tube as the tube passes over the area being treated.  It is usually not very painful.  Most patients complain of soreness like a tough work out at the gym.

As the term liposuction implies, fat is ultimately removed by negative pressure caused by a vacuum device. It may not look very glamorous or eloquent but it is very effective. Technically the negative pressure causes the ease of vaporization of the water component of fat to escape more easily. That may make you feel better about the process.
