Do robot vacuums work well on carpets with fringe edges?

Not really. Low-pile carpet is fine, but fringe gets pulled into the spinning brush and drive wheels, causing tangles, errors, or damage. Higher-end models like the [iRobot Roomba](https://www.amazon.com/s?k=iRobot+Roomba&tag=wehavethat-20) j series handle it better but aren’t perfect. Set a no-go zone or vacuum the edges yourself.
