## What reviewers say

**Roborock S8 MaxV Ultra** — Two whitelisted hands-on reviews (TechRadar, TechHive) agree the Roborock S8 MaxV Ultra vacuums very well but mops only decently. TechRadar praises reliable suction across debris sizes; TechHive reports excellent hard-floor pickup and 100% rice removal on carpet. Neither ran a weighed lab bench, so no measured percentages are recorded. Both note mopping is mixed and that the product is expensive. TechRadar additionally flags an unreliable voice assistant and poor corner pickup by the extending brush. (2 sourced reviews.)
