How we reached each verdictThe numbers behind each model's score
Narwal Freo Z Ultra
All 4 expert reviewers tested it hands-on, and they agree it is an excellent automated mopper with near-best obstacle avoidance. 3 of the 4 found carpet cleaning weak, including a 55% carpet deep-clean result in one test. Among 137 owner comments (89 first-hand), the most common praise is mopping (20%), navigation (19%) and suction (18%). Durability is the big worry. 11% of owners say it broke or died, 29% of comments mention some failure, and the reliability score is just 27. It is also a newer model with a limited long-term track record, so the evidence on lifespan is still thin.
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.
