Spending toward the top of this cap gets you the machine that cleans its own insides. The S6 Stretch sends 158F fresh water through the pipe as well as the roller during its Flashdry cycle, so the passage that normally goes sour is flushed after every job. That is a bigger gain than any headline suction number in the guide.
The body is the second reason. HyperStretch compresses the machine to about 5.1 inches and the handle reclines to 180 degrees, which puts it under furniture that a bulky washer cannot enter. Forty minutes of run time covers a mid-sized home. It sits in the upper middle of the price ladder, above every robot in the set except the Roborock.
The cost of all that engineering is more joints to look after. Check the hinge areas for caught hair monthly, run the Flashdry cycle every time, and keep the dock on a level surface.
