Bests & Worsts Reviews from Amazon

First impressions, it looks very slick. It comes out of the box almost ready to go. I just had to plug in the docking station. The Android app installed on my phone and connected to the robot via my wifi flawlessly. Then I kicked off a cleaning routine...and it complained about it's bumper being stuck. The help docs told me to tap the bumper to unstick, which I did several times, but this did nothing. So I tried putting it back in its dock, and that somehow fixed the problem, and it completed its cleaning routine. Then a few days later, I tried running another cleaning routine. It completed it and then went back to its dock. However, before docking, it starting to spin around. It did about a dozen revolutions before it stopped, turned its status light red, and again reported "bumper stuck, tap bumper to unstick". Again, it's bumper was not stuck, but I tried tapped it "to dislodge debris", and again, that did nothing. Unfortunately, putting it manually back in its dock did not fix it. As soon as it undocks, it complains about its bumper being stuck. As the bumper moves freely (I can even hear the little click of the contact switches activating), I assume it's probably a defect in one of the switches. I've contacted iRobot, but so far I haven't heard back from them, making this $1000 robot a glorified paperweight. I've heard the horror stories about their robots breaking down after a few months, but I didn't think it would happen after a couple days. It's especially frustrating, because when it works, it works quite well. That should be IRobot's new motto... Edit 2019-5-21: After working with their customer service, and proving the defect with some photos taken with my camera, they provided a replacement unit that worked perfectly out of the box. It's ironic that of all the sophisticated technology in it, I'd get one with a bad bumper switch, which is arguably the simplest component. Their customer service ended up being very helpful and were able to resolve the issue.
