Review on High-Quality BBT BAMBOOST Rubber Replacement Brushes for iRobot Roomba i7 i7+ E5 E6 E7 Vacuum Cleaner - 2 Set by Sarjus Baer

Issue with these product records randomly switching between different Chinese manufacturers. The one we received is NOT compatible with i7 Roomba. One of the brushes should have a square connector and the other hexagonal. (Also in the pictures). The set we received had four brushes, all with hex connectors. I really wish it was easier to find a genuine replacement brush or if there was a single manufacturer product page so you know what you are actually getting.
