Unfortunately I learned the lesson of ordering non-Roomba parts. I installed new garbage extractors and now Roomba is CRAZY noisy! I had to put the old garbage extractors back on my Roomba because the replacement units make a ridiculously loud noise when the Roomba is cleaning. Maybe I just got a defective product? I'm not sure. I've tried both sets of garbage extractors and encountered the same problem with both sets. Please watch the video to hear the noise level for yourself. And yes, they installed correctly. Unfortunately I'm disappointed.
