General description This vhbw Magnetic Boundary Tape Marker is a practical solution for creating virtual boundaries for your iRobot Roomba 676 Robot Vacuum Cleaner. This magnetic strip allows you to easily define the operating environment and close off areas where the robot may frequently get stuck, such as doorways or at the top of stairs. The robot automatically detects the strips and is diverted to continue cleaning in designated areas. The strips can be cut to size, providing flexibility to adapt and personalize them to your household needs. One side features a self-adhesive surface for easy installation, and they are designed to be strong enough to stay in place while being light enough to avoid leaving marks upon removal.
