This replacement part was a major disappointment. As a result of my tests, I determined that it did not work properly and did not improve the vacuum's performance at all .THE only positive aspect is that it was easy to install. Unfortunately it did not improve the suction power or performance of the vacuum. I had to return it and I would not recommend this product to anyone. It was a waste of money and did not live up to its promise. Home and Kitchen owners beware..
