What owners say

Owners of both robots like what each does well, but they are separated by a mop and a price. eufy Omni S2 owners say the roller mop lifts stuck-on dirt that pad-based mops leave behind and that suction stays strong even as the bin fills, and they rate the obstacle avoidance among the best they have used for dodging cords, toys and pet dishes, though a 98 mm body still will not fit under some low furniture and the dock itself is large. iRobot Roomba 205 owners instead like a compact charging base with no bulky dock at all, thanks to an internal DustCompactor that cuts how often the bin needs emptying, and call the LiDAR mapping accurate even in the dark, but several say a full floor still needs more than one recharge cycle and this model has no mopping at all.
