You have to find a balance.
You can clean your fine china with steel wool and a power washer, but do you need to.
As far as premature wear of a carpet. I have never heard of a Royal, Simplicity, Riccar or even Kirby causing wear, as they all have a Gold rating with CRI. However, I have heard complaints bout Dyson causing damage.
My look at it is: If your carpet is so delicate that you can only clean it with fairy wings and pixie dust; you may want to stick to a straight suction cleaner--or replace the carpet.
