I used this boundary strip to prevent my Roborock E Series from falling on the carpet. It lets the vacuum through to the brim, clearing everything in between. Setup was pretty easy, but the description in the listing calling it "Mag Tape" is a bit misleading. I used a magnetic strip and small pieces (1.5 inch) of double sided tape to spread around the edge. It wasn't a huge hassle, but I expected the glue to already be on the strip. However, the product works well, so I'm happy!
