The Stan-Vac was a vacuum sold by a Stan Pines when he was a traveling salesman in his younger years.
When Stan was younger, he was a salesperson of the Stan-Vac. He went door-to-door selling his merchandise. However, the product wasn't very successful, due to the catchphrase, "Stan Vac: It sucks more than anything!"
Eventually he retired from door to door selling and settled down in the Mystery Shack, in Gravity Falls, Oregon. His traveling case gathering dust in the corner of his bedroom, and the vacuum in the closet.
The Stan Vac looks like an old vacuum, but with the words "STAN VAC" on the bag.
