User Manual Ninja RV720 Vacuum Cleaners

The strips are to keep it from going to a place. So if you have a room you don't want it to go to, you put the strips on the floor in the doorway and it will stay out of the room. I have not had to use the strips. If i was using it where there were stairs going down then I would put the strip there just to make sure it didn't fall down the stairs although I think it is supposed to detect that. But I would be a little paranoid about an expensive item.

To me it seems random although it is supposed to have an algorithm to do cleaning. it is definitely not organized as if you were mowing your lawn. It does part of the living room and then goes into the kitchen for awhile, comes back out and does more living room including part that it did already, then it wanders down the hall, then back into the kitchen, etc. It is definitely organized about how it does walls. It gets close but not against them and then it goes back and goes right up against them. I'm sure there is some cleaning logic to all this but it seems semi-random to me.
