Here's a blast from the past: Hoover vacuums has reissued a modern day version of their 1954 floating canister carpet cleaner! Using exhaust air, the spherical little space-age inspired sputnik of cleaning utility literally floats on a cushion of air, and Hoover has brought the Constellation back with improved features like a HEPA filtration and twelve foot hose with telescoping handle. The reviews online from owners are positive, and I love the simple design that forgoes the current trend of overly accessorized upright vacuums. The only caveat is learning how to maneuver what is basically a small spherical hovercraft, but that seems sort of fun, and owners report that it's an easy adjustment. I guess I'll know myself in a few days when mine is delivered!
