Does anyone know of a vaccum cleaner specifically designed to clean hair clippings off your neck and clothes after a hair cut?

When I get a haircut the barber uses a soft bristle brush to clean up the clippings by brushing them to the floor.
However, there are still clippings down my shirt, on my collar, on my shoulders, and loose clippings still on my head. If I didn’t shower before bed they would be all over my pillow.
Does any barber or hair stylist vacuum the clippings so you are presentable and not itchy right after the hair cut?
Does such a vacuum exist?
Note, I am not talking about the Flowbee hair cutting system which cuts your hair under vacuum. I am talking about a small vacuum cleaner that is specifically used to clean down shirt collars and around your neck.

Is this available already or is it an invention that needs to be made?
