Received the Shark ION Robot Vacuum (model RV754) about a week ago. Easy to set up. Robot maps your house before doing the work. The Shark app allows you to adjust the map, add high traffic areas or ‘no go’ areas. You do have to clear up cords or toys (kid or pet) up off the ground. But not having to vacuum every day (we have a shedding dog and cat) is a blessing. Yeah it’s a bit loud. Yeah it can’t get every single surface (under low laying furniture or tight corners). Yeah you have to do regular maintenance (clean long hair or whatever out of the roller brush).  But it does the job I wanted it to do. The only better thing would be if I had gotten the self empty one. Other than that highly recommend.
