Hard to believe, but I cleared all of this from one vacuum inlet on a service call in Stamford.
Now, as much as I would not recommend you vacuum any of the items in the below picture, a properly-installed central vacuum system should not clog, even if you did.
I can't stress enough how important it is to get the installation of the central vacuum pipes correct. It will save you money and time because it will work well, and be trouble-free. Other than simple periodic maintence, there isn't anything to do but enjoy your clean home.
