How we reached each verdictThe numbers behind each model's score
Dreame X50 Ultra
All 6 expert reviewers tested it hands-on and rate it among the best robot vacuums available, giving an expert score of 86, praising pet-hair handling, threshold climbing and dock automation. Owners are cooler, with a score of 65: 37% of 554 owner comments praise its cleaning and 24% its mopping, but 14% complain about navigation and 9% say it broke or died, with failures mentioned in 13% overall. Retail ratings are strong, with 4,206 of 5,702 star ratings at five stars, though 522 are one or two stars. Evidence is mixed on battery life and suction, and long-term reliability data is limited.
Roborock Qrevo Curv 2 Flow
All 5 expert reviewers tested it hands-on, and 3 of 5 call it best suited to homes with mostly hard floors. Mopping is the headline: Wired, Tom's Guide and ZDNet rate it strongly, while Vacuum Wars found dried stains among the weakest it has measured, and RTINGS saw no improvement over the original Curv. Owners are broadly positive, with 45% of 215 first-hand owners praising suction and 39% praising mopping, and only 6% mentioning failures. Evidence on long-term durability and parts costs is thin, and pet-hair performance on carpet is genuinely contested.
