iRobot's poop-detecting Roomba j7 vacuum is cheaper than ever right now

Both Amazon and Wellbots have the Roomba j7 and j7 for $150 less, so you can grab them for $499 and $699, respectively. Both robots are the same, but you'll get the clean base with the j7 model, allowing you to set and forget the robot and only empty the clean base about once every 60 days. The j7 series builds upon the Roomba i7 robots with more powerful cameras, better sensors and more power. The AI-driven computer vision technology allows the device to detect obstacles and move around them as it cleans, and you can label those obstacles as permanent (in the case of a chair or another piece of furniture) or temporary. Not only does this mean the j7 robots should better navigate around things like piles of clothes and charging cords, but they can also detect a robot vacuum's arch nemesis: pet poop.
