Roomba j7+: 2500 Pa and 75 minutes for a 1,200-square-foot floor

The Roomba j7+ 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.
