Query: Repairman has it more then I do

I bought this vacuum 6 months ago. I bought it for three reasons; 1. I had a Dirt Devil before this one and LOVED it 2. it said it was a professional grade and 3. it has a 6 year warranty (thank goodness). One month after purchasing it the brush broke and although it had a warranty and was a faulty part it's not considered a warranty part, it's considered normal wear and tear. Five months after purchasing it the self propelled part quit working, the repairman replaced the part, but the self propelled still didn't work, then Dirt Devil decided to replace the entire vacuum. After returning home with the new vacuum, I vacuumed 3 average sized rooms and it was used less then one hour and the self propelled part broke on this one too. I wish I could get my money back and buy another brand, but I'm now stuck with it and the fact that it'll be at the repairman's shop more then it'll be in my home. Don't buy one!
