Vacuums like a dream! Just download the App from the App Store and the Robot is off running doing its thing. Cleaning is not so much of o big chore anymore since I bought the new IRobot Roomba j9+. This little robot takes is very simple to setup, first download the IRobot home App follow the simple setup instructions connecting it to your home net work. Then set up a mapping of the entire house ( will take 90 minutes or so) then set up a schedule within the App. Once all that is done it's off working for you. The home docking station is where it will charge and empty its container of dirt from vacuuming the floor. The Robot is pretty quiet while it is running its coarse, but while it is docked and cleaning out the dirt it has collected into the filter inside the docking station it gets pretty loud. The bottom has two rubber wheels that grip really well on carpet or tile and has sensor and cameras that detect objects. Overall it's a really great vacuum and cuts my cleaning time in half.
