 Scooba's Virtual Wall® The Scooba Virtual Wall creates an invisible barrier that Scooba will not cross. Virtual Walls can be set to block areas from three to eight feet wide. TIP: Use the Virtual Wall to block doorways or to keep Scooba away from cords. The Virtual Wall beam is keyhole shaped. A small halo prevents Scooba from bumping the Virtual Wall and a larger lobe-shaped section blocks off areas of your home where you don't want Scooba to go. Virtual Walls require 2 "D" batteries. Virtual Walls will automatically shut themselves off at the end of a cleaning cycle. TIP: F or best performance, place the Virtual Wall on the outside of the doorway you wish to block, and always set the Virtual Wall to the shortest setting possible. 16 iRobot Scooba Owner's Manual
