It took me five years to remove all the carpet from this house after we moved in. I had severe asthma back then and had to decrease two dander and dust to be sure I didn't trigger my asthma. When we moved in every room but the kitchen and bathroom was carpeted in matted green shag carpeting I think had never been deep cleaned. My stepson and wife systematically removed the carpet, starting in my bedroom. We did clean the carpets with those rental Steelers when we moved in. Oh, the carp that poured out of that tank!
The house has no carpet anywhere now. Just throw rugs. But I know intimately about cleaning carpets. Have fun, Terri.
