Bests & Worsts Reviews from Amazon

We bought this 34 days ago on Amazon and didn't get the extended warrantee because Shark's is "five years". Well, it completely quit spinning on the 33 day. I did everything that the troubleshooting guide said to do. Seems like the transmission on the roller brush is stuck or died. It will not spin. Called Shark expecting their famous five year warrantee to be honored. Was told the roller brush part of the "cleaning head" is a "wear and tear" part not covered under warrantee. Said that "normally this is $99 to replace, but we'll be nice and send you one out for $12 shipping". I guess I should be happy that Shark is only charging me $12 to replace a part on a vacuum that is a key part used 3 times??? Buyer beware!! Get the extended warrantee from Amazon and research if the "power head" is covered -- the part with the roller brush. Edit - Figured out what was wrong with this vacuum. SERIOUS design flaw. The area around the vacuum belt is plastic. If you run this for over 30 minutes, IT MELTS!! Shark has to know this. I just can't believe this thing made it past their QC department. A good vacuum, in a QC/QA test should be able to run for hours upon hours no issues. This thing heats up and melts. We have a fairly big house with lots of carpet. If you're going to buy this, only do one or two rooms at a time and then two or so more rooms the next day. Anything over 15 minutes and you risk literal melt down! They sent me the replacement "power head" that I mentioned above. Worked twice and melted down after 40 minutes of use!
