iRobot's latest Roomba that can detect obstacles — including pet poop — along its cleaning journey 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. iRobot even has a Pet Owner Official Promise (yes, P.O.O.P.) which states that you'll get a new robot vacuum if your j7+ runs into poop in the first year of you owning it.
Aside from that, the j7 series takes advantage of iRobot's improved mobile app, which lets you schedule cleanings and set routine triggers. You can also label rooms in your home after the robot has created a map, so you can better direct it to a specific room when you only need a quick clean.
While the clean base included in the j7+ package isn't necessary, it takes the convenience level up a notch. Instead of emptying your robot's bin after every job, the j7+ will automatically empty its contents into the clean base when it's done. You then only have to worry about emptying the base once every two months.
