This iRobot accessory is exclusively compatible with Roomba e and i series Roomba like the Roomba i7150 and contains two extractors. These are flexible rubber brushes that are in permanent contact with your floors to ensure the effectiveness of your vacuum cleaner on both hard floors and carpets.
The first brush is in charge of removing the dirt by a friction system and the second one pivots in the opposite direction to project this dirt towards the suction. This set of two multi-surface rubber extractors for Roomba e and i series will allow you to properly maintain your vacuum cleaner over time.
