They showed this on the UK tv programme "Tomorrow's World". The person receiving the haircut was distressed at the results.
TW was great because they demod the tech live and it often failed. Watching someone Getting a terrible haircut, live on tv, and being visibly upset by it was interesting.
I thought Flowbee was just clippers - the thing I hate most about cutting hair is the hair getting everywhere, especially short clippings. That's exactly the pain point being addressed with vacuum haircutting isn't it.
The vacuum also provides suction to pull the hair straight, I think. Notice how a barber pulls your hair out straight with a comb to see the length while cutting? The suction gets you that service.
