What owners say

Owners of both Roombas praise the AutoWash dock that empties the bin and washes and dries the mop pads, and strong pickup of pet hair. iRobot Roomba 415X owners single out suction that pulls dust from floor cracks, quiet overnight runs and a slim body that reaches under beds, and they complain about an app that fumbles room names and water-tank errors, hair wrapping the mop module and a mop that does not replace scrubbing stubborn stains. iRobot Roomba Plus 505 owners talk about fast, accurate first maps and vacuum and mop runs that can be combined or split, while their gripes are a loud dock cycle, bumper-stuck or docking errors after a few months and warranty trouble when bought from third-party sellers.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
