iRobot Roomba j9+ Self-Emptying Robot Vacuum
Verdict
The iRobot Roomba j9+ is a high-end robot vacuum that shines on hard floors and low-pile carpets, offering powerful suction, excellent obstacle avoidance, and largely hands-off ownership. It is loud, struggles with corners and medium to high-pile carpets, and costs more than older Roomba models, but for many homes it remains one of the best all-around smart vacuums you can buy.
