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 S8 MaxV Ultra
The evidence here is deep: 7 hands-on expert reviews and 456 owner comments, 411 of them first-hand. Experts score it 81 and owners 73, with 4 of 7 reviewers calling it their best or top-tier robot cleaner, and 38% of owners praising its suction versus 5% complaining. Mopping is more divisive among experts (5 of 7 note streaks, stubborn stains or only okay results), though owners lean positive at 27% praise versus 8% complaints. The main caution is durability and value: reliability scores 64, 15% of owner comments mention failures, 9% say it broke or died, and 7% cite poor customer support.
