Bests & Worsts Reviews from Amazon

I purchased this product back in November 2018. It is just now the beginning of March 2019 and a piece that connects the roller is broken. It's a little black plastic connector piece that allows the roller to roll. Since it was such a new purchase, I called Shark to see if we could get a replacement connector piece. I was told that they only warranty the motor, and I would have to purchase a new roller. The roller works fine and does not need to be replaced. All I needed was the little black connector to the roller replaced. It should have been at max a $5.00 purchase, but no, I could not just purchase that piece. I was told that they do not sell that by itself and that I would have to purchase a whole new roller. The roller replacement would cost me $89.00 and the shipping will be $20.00. After tax, the total would be $111 and some change. This is ridiculous and I told them this. After a bit of back and forth, they did cut the cost in half and waived the shipping. Then after I agreed to the purchase, I was told that the roller was back ordered for three to six weeks. This tells me that this is a common problem with this device. That the replacement is in such demand, it has a three to six-week backorder. After this incident, I will probably not purchase another Shark device. Their warranty is not complete, and they do not back replacing faulty pieces of equipment.
