Received this vacuum for Christmas and used it hard in our house of 4 dogs for 3 months. Then, I went to turn it on a few days ago and it made a strange sound and died entirely. No clogs. Clean and looking great; filter has been cleaned; hit the power button and literally no sound; no clicking; no attempts to revive. I gave it some stars because while it was still alive. It was working great on our dog hair and I was really pleased with the amount of suction. My extremely handy husband is entirely baffled and cannot fix this either.
