Roborock Saros Z70
An unusually innovative premium robot rather than an automatic 'best'. Its core cleaning, navigation, mopping and dock specification is genuinely high-end; the mechanical arm is the differentiator, but current independent testing says that feature is still inconsistent enough that price alone should never elevate it.
The main things to know before buying are the robotic arm is innovative rather than proven essential; independent reviewers found it inconsistent in real homes and core carpet / raw pickup performance does not automatically beat cheaper premium rivals.
