This combo Roomba was easy to inbox and setup. Charged fairly quickly. Was quite boring to watch and seems like it is a lengthy process. But if you leave it to do it's job and not sit and stare. It does what it says it will. With dog ohs our house stays dusty and hairy. I could clean several times a day and still have hair everywhere. So a vacuum I can schedule to clean while I go do other stuff is what I'm talking about. In my situation the size of the machine doesn't hold a lot of what it picks up. So I have to empty it often. Overall I think I can do the vacuuming myself faster and know I'm getting stuff up cause I can see what I'm getting up as I'm doing it. But I have lot of other things to do so this is ideal. Pretty good precision, doesn't bang into furniture. Pretty cool vacuum.
