iRobot Roomba j9+

The iRobot Roomba j9+ combines obstacle avoidance AI that recognizes 80+ object types (including pet waste) with automatic dirt disposal into a 60-day capacity base, outperforming #8's Roborock S8 Pro Ultra in object detection accuracy by 30%. Its PrecisionVision Navigation maps homes in 3D, while the upgraded suction power of 2500Pa handles deep carpet cleaning. After Amazon's acquisition, Roomba's Alexa integration deepened, making it the most capable robot vacuum available at under $900.
