I love my new rooba, and I'm using it constantly. Having the app and starting remotely is a fanatastic feature, and the app alerts you if the Roomba get stucks and needs you to get it moving again. Much quieter than older versions, but the base is a little loud for a few seconds while it unloads the Roomba. Setup was quick and easy, and the Roomba even talks to you to give instruction. The design is more sleek than previous models, and it also seems to navigate better than before. Super excited to not be vacuuming and empting the dust bin every week!
