LiDAR navigation separates serious robot vacuums from random bouncers

|LiDAR navigation is what separates the serious vacuums from the random bouncers. Models with it — the Roborock S8 Pro Ultra, Dreame L20 Ultra, ECOVACS Deebot X2 Omni, Samsung Jet Bot AI+, and Shark IQ Robot XL — actually map your home and clean systematically. Models without it — 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.
