iRobot's Roomba 690 vacuum offers lots of functionality for the price, including control via smartphone and support for voice commands through smart home devices. I finally had my wood floors down and I wanted something that could clean them every day.  We try out the Roomba 960 and the affordable 690 and go through our test.  These are Amazons best pick for vacuums.
