Intellibot auto-scrubbers and vacuum allows the operator to quickly switch between manual cleaning and Hands-Free Cleaning. At the push of a button the operator can walk away to clean in other areas while the floor is cleaned. The Operating System uses a touchscreen and requires no programming. It incorporates up to 19 sensors, giving the robot a 360-degree view of its surroundings, and allowing it to operate and clean on its own. Sensors detect obstacles as well as people -- stopping to let them pass before proceeding -- and stairs, to prevent unwanted spills.
