Roomba j7+ vs 600/900-series Roombas: j7+ avoids obstacles and empties itself

The j7+ uses a camera and AI to recognize cords, socks, and pet messes instead of plowing through them, while older Roombas just bounce around blindly. It also empties itself into a 60-day dirt base, saving you from frequent dustbin cleanouts. The j7+ feels like it’s actually thinking — the others just bump and hope.
