iRobot and their Roomba product line is riding on their namesake only. Roborock and other competitors are miles ahead of them when it comes to technology. It took a top of the line Roomba from 2021 about 4 hours to fully map my downstairs. Meanwhile the top of the line Roborock from 2022 did it in 15 minutes with its Lidar. And this is just one example. My roborock literally mops, cleans and dries its own mop, refills itself, empties itself, I can two way video call with the damn thing, it's just insane.

iRobot has not innovated their products in any meaningful way in over a decade.
