iRobot Roomba j9+ Review: The Robot Vacuum That Finally Avoids Dog Poop

The Roomba j9+ is iRobot's answer to the question every pet owner has asked: "What if my robot vacuum runs over dog poop?" With PrecisionVision navigation and the P.O.O.P. (Pet Owner Official Promise) guarantee, the j9+ promises to identify and avoid pet waste, cords, socks, and shoes. After two months with two Labrador retrievers who shed constantly, here's the real-world verdict.

Obstacle Avoidance: Does It Work?

In over 60 cleaning cycles, the j9+ successfully avoided: dog toys (100%), charging cables (95%), socks (100%), shoes (100%), and yes — a simulated pet accident using a realistic prop (success!). The camera-based system takes a photo of each obstacle and labels it in the app. A few charging cable misses occurred when cables were partially under furniture, but overall performance is dramatically better than previous Roomba models.

Cleaning Performance

The j9+ features 100% stronger suction than the Roomba i7, dual rubber brushes that resist hair tangling, and a Dirt Detect sensor that identifies high-traffic zones for extra cleaning. On hardwood floors, it captured 98% of visible debris in a single pass. On medium-pile carpet, it needed two passes for deeply embedded pet hair but still performed admirably.

Clean Base Auto-Empty

Included with the j9+, the Clean Base automatically empties the robot's bin into a disposable bag that holds 60 days of debris. This is the killer feature — you genuinely set it and forget it for two months. Replacement bags cost about $5 each.
