This is my first robot vacuum and I'm kicking myself for not getting one sooner! This thing is amazing! I have a black dog so there are constant clumps of fur balls all over and it's such a pain to constantly take out a regular vacuum, not to mention three kids and constant crumb trails everywhere. This Shark was so easy to connect to make it completely hands-free and setting it up and mapping everything out was simple to follow. I have hardwood floors throughout my house with area rugs in a few rooms, and this has no issues getting onto and off of the rugs and vacuuming the rugs as well leaving those pretty vacuum marks. It seems to have a pretty powerful suction and it is not loud. It also automatically goes back to the station to self-empty which is so cool, and then I just empty the bin about once a week, sometimes less. It has so many cool features and saves so much time and energy. It is truly a game changer!!!
