I don't understand why people are damaging their carpets with spikes. I have had my Mirage's(mains) on spikes since I bought them over 10 years ago, and I've never damaged a carpet. They are called carpet spikes...they are supposed to be used with carpets.
I am having my home remodeled from a fire...and we will not have carpet anywhere...except maybe an area carpet here and there for looks...but no more bacteria & dirt trapping wall to wall shite....anyways...I won't be able to use spikes on the new floors. I have ordered a couple of sub dudes...and I am going to try those without the spikes first. Then I can also use the spikes on the sun dudes to see if it helps. But I believe the sub dude without the spikes will work best...but of course this is just an educated guess.
Cheers,
