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.
