This new Roomba S Series product really hits home. The automatic dirt disposal is a home run. I have a dog that sheds constantly and my previous Roomba bin would fill up before the cleaning job was complete. Problem solved with new automatic dirt disposal. It simply docks and empty's the bin and resumes its cleaning duties. My carpets and floors have never been cleaner. Another bonus is how it maps out your entire home and allows you to segment the different rooms. Then you can simply schedule cleaning jobs based on rooms that require more attention. The only drawback I noticed was when using the "Detail Clean" mode it's very loud. That's easily avoidable by scheduling the cleaning jobs when you're away. And if for some reason you needed that quick clean you can simply set the Roomba to "Quiet Clean" and problem solved. They really did think of everything when building this new model.
