Well,
Well, its a swiffer pad.
this is more of a vacuum, because it has a suction nozzle at the bottom.
This is not a Roomba but its made by Dirt Devil and doesent have any brushes (except the whiskers at each edge on the front.)
Also, its way lighter and noticibly smaller than the Roomba and much quieter so your dog wont be bothered (well at the begining maybe a little than he will definatley get used to it!)
