The iRobot Roomba MA01730 Dual Mode Virtual Wall Barrier Sensor Boundary is a genuine OEM product designed specifically for iRobot Roomba vacuum cleaners. This virtual wall barrier sensor is essential for creating boundaries to block off certain areas in your home, ensuring that your Roomba vacuum does not enter these areas during its cleaning cycle. The sleek black color and compatibility with iRobot Roomba models make it a perfect addition to your household cleaning routine.
It works great but too pricy. Found out my old virtual wall type that takes Type D batteries works just the same with E series Roomba. I would never recommend these Unless you lose your old set. Now I have two walls the one that looks like a brick and the other that is far smaller and triple the price. Newer units can take series 531+ virtual wall units. I tested it out by accident and it works!
