Roborock Saros Z70 Review: OmniGrip Doesn't Quite Work

My job is one in which companies make big promises and rarely follow through. In that respect, it's remarkable that Roborock launched the Saros Z70 with OmniGrip at all. A robot vacuum with a retractable arm that can identify, pick up socks, and put them away seemed like such a big leap forward that I have to applaud Roborock for releasing it for consumer purchase at all. That said, the robot arm … doesn't really work. At least, it doesn't in my home, which is exactly the type of home that would call for a helpful robot arm. I've been testing it for two months now, and Roborock's machine learning hasn't helped it out yet.
