Query: warranty void

Although this vacuum works ok....after using it for less than a year, the power head broke. I called Dirt Devil. They proceeded to tell me that, although it was technically under the 2 year warranty, they could not replace my part based on the fact that it wasn't a "manufacturer defect". This is their way of saying, "we pretty much don't stand behind our products." They can't stand up to any sort of wear or they would stand behind replacing parts that break within the first year of use. So, I ended up having to pay for the replacement attachment myself. I am highly disappointed in the quality of the product and the customer service of the company!!
