How we reached each verdictThe numbers behind each model's score
iRobot Roomba j7+
Nine hands-on expert reviews agree the j7+ is among the smartest robot vacuums, with standout camera-based obstacle and pet-waste avoidance, giving it an expert score of 84. Owners are cooler at 60: 26% praise its cleaning and 19% its navigation, but 18% mention failures, 10% say it broke or died, and 12% complain about customer support, which pulls reliability down to 56. Experts split on carpet cleaning, and several note weak edge cleaning, a loud self-empty cycle and roughly 75 to 86 minutes of battery life. With 421 owner comments and about 8,500 Amazon ratings averaging 3.8 stars, the evidence is broad. Long-term durability data rests mostly on owner anecdotes and one multi-year expert report of a battery replacement after about two years.
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.
