Robotic vacuums used to be a luxury product, but they've trickled down into the mainstream. For lots of folks, the math just works out: It costs less than the value in saved time, and those extra moments can be spent more productively. So if you want a high-end model with more granular controls, room mapping and detection, and Assistant integration, then the Roborock S6 might be a good choice. That is, if you can stomach the $650 price tag and a few noteworthy drawbacks.
