Does the iRobot j7+ actually avoid pet waste, or is the P.O.O.P. Promise just marketing?

A: The j7+ genuinely avoids pet waste — in a test with fake poop, it stopped six inches away, backed up, and planned a path around it. Its camera system was trained on thousands of images of pet waste, so it recognizes and avoids the mess instead of smearing it. The P.O.O.P. Promise backs this up by offering a free replacement if it ever fails.
