Review on Jorllina Replacement Roller Multi Surface Brushes Vacuums & Floor Care by Melody Stephens

I tried this to save money. Learn from my mistakes: It's garbage. The first set started spinning and broke off the reel on the first task. I installed a second set and it sounded like my car was sucking up Legos (if you have a Roomba and kids you'll be familiar with that noise). This noise is very loud and like something grinding in the car. The problem is that they sound exactly like this and I don't understand why or how they could come out and be so bad.
