V-Bot cleans carpet, wood and tile floors automatically while you work, sleep, read or take in a movie! V-Bot uses smart programming technology to move about and clean on its own - it even automatically detects and avoids stairs. Use it on carpet or attach the rotating brush and sweep all your hard floors. Built-in smart technology automatically determines one of three preprogrammed patterns: random for tight spaces, spiral for large open areas and along-the-wall for room perimeters. Also has whisper-quiet operation, easy-to-empty internal dust bin, long-life rechargeable batteries for up to 45 minutes of operation per charge and AC adapter. 13-1/2-inch by 14-inch by 3-3/4-inch.
