Flowbee Vacuum Haircutter
Flowbee Haircutting system is just one of the infomercial products that you never admit to having. Probably one of the most ridiculous infomercial products I have ever seen that actually works.
Simply hook it up to your vacuum cleaner and off you go. The way it works is by the suction from your vacuum cleanmer which pulls your hair to the desired length and then with its blades gives it a perfect cut. No more expensive barbers every month.
