Is the Roomba j7+ powerful enough for a 1,200-square-foot home?

The [Roomba j](https://www.amazon.com/s?k=Roomba+j&tag=wehavethat-20)7+ puts out 2500 Pa of suction and runs for about 75 minutes per charge — enough to cover a typical 1,200-square-foot main level in one go. It’s not the most powerful on paper, but the combination of pet waste avoidance and auto-empty makes it a practical sweet spot. The battery is the real limiter: larger open-concept homes might need a mid-clean recharge.
