How we reached each verdictThe numbers behind each model's score
Dreame L40 Ultra
All 6 expert reviewers tested it hands-on, and 5 of 6 were clearly positive, praising its dock automation, obstacle avoidance and mopping; RTINGS was the outlier, rating its carpet, fine-debris and pet hair cleaning as mediocre due to erratic pathing. Owners largely agree with the positive camp: of 428 first-hand comments, 53% praise suction, 43% mopping and 31% navigation, while complaints are small (6% navigation, 6% noise, 5% mopping). Reliability looks good so far, with only 5% mentioning failures and 2% saying a unit broke or died, but Vacuum Wars notes long-term reliability is unknown because the model is new. Hair tangling is the murkiest area: Vacuum Wars found the standard brush tangled badly, while other reviewers using the Tri-cut brush reported few or no tangles.
Roborock Qrevo Curv 2 Pro
All 3 expert reviews are hands-on, and all agree it is a strong vacuum, especially on carpets and rugs, with an average expert score of 77. Owners are slightly warmer (81): of 120 comments, 30% praise suction and 26% praise mopping, while only 6% complain about mopping and 6% mention a failure, which supports a reliability score of 86. The experts are harsher than owners on mopping, with 2 of 3 reporting smears or weak stain removal, and all 3 flag poor detection of small objects. The evidence is thin in places: there are only 3 expert reviews, no Amazon data, confidence is medium, and Tom's Guide noted the US launch was not yet available, so there is no confirmed US price.
Roborock Qrevo Edge 2
All 3 hands-on expert reviews agree the Qrevo Edge 2 cleans well. Vacuum Wars measured 94% sand removal from carpet and 89.5% pet hair pickup, and the self-washing, hot-air-drying dock wins praise across the board. Owners are broadly positive: of 240 comments, 37% praise suction, 25% praise mopping and 19% praise navigation, while only 4% mention failures. The weak spots are obstacle avoidance (Vacuum Wars logged 14 of 24 objects avoided), a small dustbin, and TechRadar's note that it misses edges and is expensive. The expert evidence is thin at just 3 reviews, and retail ratings diverge sharply: about 4.6 stars at the brand store and Google versus 3.6 stars from 80 Amazon votes, so confidence is medium.
