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.
Our take so far
Roborock Saros Z70 has useful exact-model information, but the fuller independent assessment is still being completed. Use the known features as a guide rather than a promise of class-leading performance.
Manufacturer specifications and independent reviews describe its features and limitations. These references support further research; they do not by themselves establish how well it will suit your home.
