    Hair clippers that attach to a vacuum hose. The vacuum pulls the hair against the clippers at the length set by the inlet tube and then disposes of the offcut. It's a very efficient way to give yourself a consistent haircut. It's not consistently good, but.... yeah. It was never hugely popular in the US, but they did advertise a lot back in the 90s.
