The Neato XV Signature Pro is a reasonably priced robotic vacuum cleaner that uses laser guidance to effectively clean every square inch of your home. Robotic vacuum cleaners have been around for a while, but with prices in the $700 range, you'll need deep pockets to take advantage of their time-saving abilities. Not so with the Neato XV Signature Pro, a powerful robot vacuum that cleans your floors for hundreds of dollars less than the competition. Priced at $449, the Signature Pro isn't cheap, but compared with the $800 Roomba 880 it's a relative bargain, and it picked up everything we threw at it.
