Review on 🧹 ECOMAID Bristle Brush for iRobot Roomba 600 700 Series | Compatible with Roomba 620 630 650 660 680 760 770 780 790 | Vacuum Cleaning Robot Accessories by Barb Gordon

Not very good. If we are talking about a cheap Chinese fake product, then this is a good example. There are very few bristles, and they are all made of a very thin, fragile, soft material. I would come back for a refund if it was worth the time and effort but hopefully an honest review will save someone else from making the same mistake.
