Review on Theresa Hay Replacement Replaces Pre Motor by Tammy Pochmara

I installed all of these new parts as soon as I received them. Everything seems to be fine with both the filter and the side brushes. My complaint would relate to the roller brush. My shark stopped for no reason with blue spots and dock lights flashing. I had to constantly clean the roller brush even when it wasn't that dirty and hit the "clean" button every few minutes just as it was about to stop. No obstacles and nothing but what is usually sucked away. It was so annoying that I stopped it altogether. So I went to the Shark brand official website and ordered new stuff. It was worth the extra money because now my Shark robot vacuum is working as usual again!
