has anyone used one of those automatic vacuum cleaners??
Yes, they only work decent on wood floors,and it takes them a very long time to do the job, you can do it yourself in a fraction of time compared to how long it takes the robot to do it and some time it won't get the whole area, justs keeps on cleaning the area it just went over, I think they are worthless, just a novelty devise.I'll sell you mine if you really want one (LOL) oh... and they are worthless on tiled floors.
