Might save you some money.
We recently had new carpeting put in MBR. It is a Shaw product that is a little more plush than we had before. We were also due for a new vaccume and got a Dyson DC41.
The Dyson vaccume works great on the hardwoon and tile, but just gets stuck in the carpet. Won't push forward at all. Seems to be too much suction. Checking both Shaw and Mowhawk websites they don't have Dyson on their list of recommended vaccumes. Calling Shaw resulted in them telling me Dyson had so much suction that it would ultimately damage the carpet. Called Dyson and they said their product works best on Berber or very low cut pile and agreed it would damage a more plush carpet.
Of course we can take the new Dyson back and get our money, but who would think you need to check what type of vaccume you need before you buy new carpet.
