## 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.)

**Dreame L20 Ultra** — Three whitelisted hands-on reviewers (TechRadar, TechHive, Pro Tool Reviews) all praise the L20 Ultra's strong suction, thorough edge-reaching mopping and near hands-free automated base station, while flagging its ~$1,500 price plus ongoing consumable costs. None published lab measurements, so all verdicts are qualitative. They split on obstacle handling: TechHive and Pro Tool Reviews found object recognition/avoidance excellent, while TechRadar called small-object and cord detection 'hit or miss'. (3 sourced reviews.)
