My Roomba can vacuum while I do other things such as relax, read, eat, or do other chores. I got the Roomba model 9S+ which is expensive, but I think is worth the price. It vacuums efficiently and empties the bin automatically without me having to do anything. Doing mapping runs so the Roomba learns the layout of the rooms is somewhat time consuming, but you only need to do that when you first get the Roomba.
