I bought these because the bristles on the old brush were worn out and I thought the new brush would pick up the dirt better. The results were amazing. I vacuumed the spot several times with an old brush, picking up the dirt each time. Not a lot of dirt every time. But when I used a new brush, I picked up a lot more dirt each time. Longer bristles lint the carpet much better. It was scary to think how much dirt was in the carpet. Easy to install on Bissell Powerhouse Turbo. I simply unscrewed the six screws on the cover, removed the cover, lifted the brush out of the slot, and pulled it out of the belt. Changed direction to insert a new brush. It took about 5 minutes from start to finish. I have had a vacuum for many years. This change should breathe new life into the vacuum.
