It's not like the automatic vacuum cleaner market could get much more crowded, but Evolution Robotics has put an interesting twist on things with its Swiffer-packin' Mint. If you'll recall, we saw this guy wiping up the downright disgusting floors of the Las Vegas Convention Center back in January, and now it looks as if production plans are moving along nicely. Equipped with a NorthStar positioning technology that enables it to never hit the same spot twice on the same run, this hardwood sweeper is now up for pre-order. Unfortunately, getting in line requires a non-refundable $20 deposit, but the outlay will be applied to the purchase price and will enable you to snag one of the first shipments this summer (which is significantly more awesome than waiting for it to hit retail shelves in Q4). Don't worry -- your Roomba won't be too envious.
