Digital Smarts: Admit it. You've probably considered buying one of these chordless devices, if only to confuse your pet. The robot automatically adjusts to different surfaces including hardwood, tile and linoleum. The vacuum robot's head was designed with pet owners in mind and picks up pet hair, as well as dirt, dust and allergens.
Of course, a key part of the allure is the robot's ability to roam your home, including those hard to reach places. Roomba also returns to its "home base" to recharge between cleanings.
