Which one to buy if

What owners say

Owners of both robots praise a dock that empties, washes and dries the mop, and both call daily cleaning close to hands-off. Dreame L40 Ultra Gen 2 owners single out the extendable side brush for corners and the value for the feature set, while noting hair that tangles in the wheels and an app with a real learning curve. Roborock Saros 10R owners, many from an older Roomba, highlight navigation that maps fast and avoids furniture without scraping it and mopping that scrubs up paw prints, with smaller gripes about the missing floor cleaner and higher water use.

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.
