Just plug in, sneak down the app and run a short wizard and you're up and running. Picked up some little stuff on the floor, then I looked at all the different carpets and thresholds and thought about how it would go. Pulled it on and stuck out. When I came home later he was under the bed, and then it was clear. The whole apartment was super clean, it hadn't had any problems anywhere. Thick carpets, thin rag rugs, a pretty solid threshold ... No problem!
Had vacuumed the day before but it had filled the entire container with dust and other scrap!
Damn what a nice thing.
