What separates serious robot vacuums from random bouncers?

LiDAR navigation separates serious robot vacuums from random bouncers. Models with it — like the [Roborock S](https://www.amazon.com/s?k=Roborock+S&tag=wehavethat-20)8 Pro Ultra, Dreame L20 Ultra, ECOVACS Deebot X2 Omni, Samsung Jet Bot AI+, and [Shark IQ](https://www.amazon.com/s?k=Shark+IQ&tag=wehavethat-20) Robot XL — map your home and clean systematically. Models without it — like the Samsung Jet Bot+, ECOVACS Deebot N8 Pro, and Eufy RoboVac 15C — bump around until they’ve covered enough ground. The difference in cleaning time and battery life is dramatic.
