This iRoomba doesn't have all the bells and whistles of some of my other iRoomba but it is a powerful device. I really only need this to get my dog's hair. They are big and hairy and leave a lot behind. Among many other things, this is the first of several recent connections to my application. I wouldn't time it for execution as these are dog toys and pets, but I appreciate the idea. This iRoomba is different because it seems to stop and pause and then start again. It also has a smaller bin than my last two. I was concerned about this last time but found that it seems to grind up dust and hair into smaller amounts. He was still able to raise the same amount. I have another iRoomba which I used daily in addition to my Dyson pets and for sweeping with a real broom but it bugged me with a bug. Unfortunately, I was able to get it working again for an extra 5 minutes by kicking it. Rest assured, that wasn't my favorite decision; however, neither the cleaning nor any other means worked. I love having a fresh iRoomba that doesn't hate me or ignore my desires and doesn't need to be kicked when I'm still in summer sandals. I have three huge dogs that leave a lot behind, as well as a cat and problematically a guinea pig. (Leaves the hay.)
