What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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.)
Praised: Strong suction that reliably picks up debris; Thorough mopping with edge-reaching spinning pads; Near hands-free automated base station (self-empty, mop wash and warm-air dry).
Flagged: Very high price around $1,500 plus ongoing consumable costs; Very large base station needs significant floor space; Inconsistent small-object and cord avoidance.
