Which robot vacuum fits high thresholds best
Top pick
Roborock Saros 10R
For a threshold-first buyer, the Roborock Saros 10R is the most balanced fit, since a liftable chassis, strong obstacle sensing and a low body come together in the same robot. The Dreame X50 Ultra is the specialist pick for unusually difficult transitions. The Narwal Flow 2 brings a roller-mop package aimed at pets.
