We found a great way to save money for our growing family (of 5 as of this mid-October). We use a device called the Robocut. There is another one called Flowbee. Both are rotary-type blades that attach to your vacuum. It sounds crazy, and it's not perfect, but it works. The cost was around $65, or so, but since I get my hair cut every 1 1/2, at $10, a pop, it will pay for itself in 9 months. It pays even faster since I would get my hair cut every month except for the cost. My wife also uses it to trim her hair and our daughters' hair. Anyone else out there use one of these devices?
