We are of the mind that anything that makes real life more like Ghostbusters is a good thing. And that's the first thing we thought of when we spotted the backpack vacuum ($200) on Hammacher-Schlemmer. Now, when it's time to do your household chores, you can strap on your vacuum, pretend it's a proton pack, and do your best Dr. Peter Venkman impression. The vacuum pack itself is seven-and-a-half pounds and sits flush against the body while the 800-watt motor is powerful enough to pick up everything, including pet hair. It even has a HEPA filter to remove allergens.
