iRobot Roomba j7+

The Roomba j7+ solved the two biggest problems with robot vacuums: running over pet waste and getting tangled in cords. Its PrecisionVision camera identifies and avoids obstacles in real time, and iRobot is so confident they offer a Pet Owner Official Promise — they'll replace it if it fails. The Clean Base auto-empties the bin so you can go weeks without thinking about it. Navigation is methodical (neat rows, not random bouncing), and it maps your home so you can send it to specific rooms from the app. Cleaning performance on both carpet and hard floors is excellent for a robot at this price. It won't replace a deep-clean with a Dyson, but for daily maintenance? It's a game-changer.
