I am going to use a Cimex on 41K sq feet of pretty well abused carpet. It has been a while since it was last cleaned. I am planning on using Encapuclean O2. Any suggestions for using this machine since I have never run one before. I have done some encapping using a 175 with pretty good results. How long should it take to do that much carpet with a Cimex? It is all cgd.
