Our Verdict
Based on our scoring, the iRobot Roomba j7+ comes out on top with an overall score of 9/10. The Roomba j7+ is the smart Roomba buy. Same PrecisionVision obstacle avoidance as the j9+ — it sees and avoids pet waste, cords, and shoes. Self-emptying Clean Base holds 60 days of debris. Imprint Smart Mapping learns your floor plan for room-specific cleaning. At its current discounted price (often $300-400 less than the j9+), it delivers 90% of the j9+ experience. The j9+ adds stronger suction and faster mapping — nice but not essential for most homes.
