Bests & Worsts Reviews from Amazon

Bought this vacuum after lots of research and reading reviews. We've only had this vacuum for 7 months. The roller brush stopped spinning halfway thorough normal vacuuming, I cleaned it out thoroughly and it still wouldn't spin, even though the green light was on. Called SHARK customer service only to be told that the motor burned out and we will have to replace the entire bottom motorized floor nozzle, which is $90 and not covered by the warranty. This is completely unacceptable and should not be considered "normal wear and tear" after only 7 months of owning this expensive vacuum. Very disappointed in SHARK and the quality of this vacuum.
