iRobot updated the Verro pool-cleaning robots much to the chagrin of our pool boy, Philip, who's getting his walking papers next week. The new 100 and 500 models join the current 300 and 600 to cover a wide array of price ranges, and probably meet most -- if not all -- of your exacting standards for water-body cleanliness. The 100 comes in at the low-end of the spectrum at $399, though it will navigate and clean any flat-bottomed pool you throw its way; the Rolls-Royce of poolbots, the 500, will do floors and walls alike for $999. Of course, you won't know anything about that -- you'll be busy lounging, working on your tan, and trying to figure out whether you want the Bentley Brooklands or Azure (hint: the Azure!).
