Is LiDAR navigation worth the extra money?

Yes, if you have more than a single room or around 800 square feet of space. LiDAR models clean in methodical rows, finish faster, and miss fewer spots. For small studios or single rooms, random navigation models like the eufy 11S MAX or ILIFE V3s Pro still do a good job the robot just takes longer to cover the same area. The Roborock Q5 and Dreame D9 are the sweet spots for LiDAR affordable.
