A user reviews the iRobot 1100 Dirt Dog Workshop Robot Cleaner: “I thought the iRobot 1100 Dirt Dog Workshop Robot Cleaner would not be effective at all. I have (had actually) a very dirty smooth garage floor with all kinds of shelves etc. under which I was almost afraid to look. Unleashing the DOG, it filled up with crud quickly, and I emptied several loads per cycle. The iRobot 1100 Dirt Dog Workshop Robot Cleaner kicked up very little dust, and after a few runs the floor looked almost new. There’s no vacuum, it’s just brooms guiding the stuff into the collection tray. To get this level of clean without moving cars etc out of the way is impressive. Given my low expectations, I was compelled to give a good review to my new friend.”
