I thought replacing this brush head on my Bissell would bring suction back. That was NOT a solution. Yes, I've done some research to find out which part is the correct one and watched a few troubleshooting videos/cleaning procedures to remove dirt/grime that is reducing suction. This new nozzle has the same low suction power as the one that came with the vacuum cleaner. I suspect this is just natural wear and tear of the machine as the suction was very strong when we first bought the vacuum in 2016. #NotARoboReview
