Even after reading the reviews about generic videos and their volume, I decided to try them anyway. I bought these on May 7th and they were delivered on May 13th, today is June 3rd. These didn't even last a month! I saw one person post the same photo as me (end chewed up and green gum in the vacuum). I hate that iRobot charges $45 on their website when you pay around $1000 for a vacuum cleaner. At $40 each they should last longer or replace the brushes with S9 (600 series). They were difficult to clean but lasted a long time. In short, don't waste your money on this, just buy OEM like I do now.
