I read it where he did say that he cleans 4 rooms in 45min and he even posted some nice cool videos. Even he is running a big ass of a tm, how are we going to categorize the pre vacuuming and pre scrubbing.In all fairness I haven't read where ACP states he does things this fast. But I think he is running about as big a truck/ system you could run so maybe so..
Im, just talking about flow here on the wand. Again, this guy on YT makes a strong case for low flow higher pressure and is getting good results.
