On January 3, 1995, U.S. Patent No. 5,377,411 issued to Demetrios Andriotis on a Hair Cutting Appliance:

Demetrios created a haircutting appliance comprising “an enclosed housing having a hollow handle connecting the housing to a vacuum source to carry away cut hairs from a subject’s head.” It sounds like a Flowbee, patented by Rick E. Hunts:

Hunts started in 1988 selling Flowbees from his garage before finding success with late-night informercials. By 2000, he had sold more than two million Flowbees.
