Roomba j7+ vs Roborock S8: Roomba wins for obstacle avoidance

The [Roomba j](https://www.amazon.com/s?k=Roomba+j&tag=wehavethat-20)7+ is noticeably better at avoiding pet accidents, cables, and toys thanks to its front-facing camera and trained object detection (PrecisionVision). The [Roborock S](https://www.amazon.com/s?k=Roborock+S&tag=wehavethat-20)8 uses structured light and is decent with furniture but struggles with low-profile cables and small objects. iRobot even offers a “Poo Promise” replacement guarantee, which tells you how confident they are.
