iRobot Roomba j9+ Self-Emptying Robot Vacuum

Meet the iRobot Roomba j9+ Self-Emptying Robot Vacuum—a set-and-forget cleaning powerhouse that delivers 100% stronger suction than previous Roomba i Series models. The j9+ combines advanced PrecisionVision Navigation with a built-in camera to map your home 7x faster than older mapping technology, creating complete floor plans after just one cleaning cycle. Its proprietary 3-stage cleaning system uses dual multi-surface rubber brushes, an edge-sweeping brush, and enhanced Power-Lifting Suction to tackle everything from fine dust to embedded pet hair across carpets and hard floors. The standout feature here is Dirt Detective intelligence—a first-of-its-kind system that learns your cleaning patterns and automatically prioritizes dirtier rooms, adjusts suction levels, and determines how many passes each area needs. The j9+ excels at real-time obstacle avoidance, steering clear of pet waste, charging cords, shoes, and furniture with confidence. iRobot backs this capability with their P.O.O.P. guarantee (Pet Owner Official Promise)—if the robot fails to avoid pet waste, they'll replace it for free. The self-emptying base station holds up to 60 days of debris in an advanced containment bag, meaning two full months between manual maintenance. This robot fits busy households, pet owners, and anyone seeking hands-off floor maintenance across mixed surfaces. At 7.5 pounds, it navigates efficiently in neat rows for wall-to-wall coverage and responds to more voice commands than competing models through Alexa, Siri, or Google Assistant integration. The trade-off for this convenience is the upfront investment and ongoing costs for replacement bags, plus the need for occasional brush maintenance in homes with long hair or heavy debris loads.
