All current Roomba models [1] have wifi and app support. The app requires an account because it's the type where even when you're at home on the same network as the Roomba, the app doesn't actually talk directly to the Roomba, but goes out through iRobot's servers. Not sure about other models, but on the 980 that I have, the app is necessary to use the full functionality.
