I just bought this vacuum cleaner at Costco day before yesterday. Put it together and tried to vacuum today. The brush roll is not spinning. I did all the checking suggested, but it is not spinning. I cleaned it (it had some hair, not much tangled in even though it is supposed to self-clean), but it made no difference. And the suction is not good. The light is green, everything is put together as it shouid be. This thing is going back tomorrow morning. I have Shark rocket, which is excellent.
