## What reviewers say

**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.)
