I have one of the older Roombas. The actual vacuuming is good but often find it easier to quickly whip round with a cordless Dyson than make sure the floor is fully clear for the robot hoover.
Tassels may get caught, mine always seems to end up sucking up some wire and children's toys that I hadn't noticed.
If your floor is clear then they're a great piece of kit.
