Robot vacuum marketing has turned into a suction arms race — 22,000Pa, 35,000Pa, numbers that mean very little without a floor to test them on. So we cleared out our test living room, scattered the same mix of debris fourteen separate times, and let every robot in this test run the exact same course: hardwood, medium-pile carpet, a rug edge, and a small obstacle field of cords, socks, and toy blocks.
None of that would matter if the basics had slipped, so that's where every run started. Suction on carpet and hard floor, mopping on dried stains, obstacle avoidance in the dark, pet hair pickup, and how hands-off the self-emptying dock really is all got the same fixed-rubric treatment, run back to back across six weeks.
