This is a ramp for overcoming level differences. I bought it to help my Roomba overcome level differences, but it didn't climb it, so I only tried it once. The double-sided tape on the back is original, but I haven't used it. Size: Width: 70 Depth: 9 Height: 3 Material: EVA foam (with double-sided tape on the back) It's a material like a firm cushion. You can easily cut it to your desired size with a cutter. It's almost new and unused, but please purchase only if you understand that it has been stored at home.
