As Marley is quite obviously new to c/c , he is simply doing the right thing and asking advise,
he may well have been misinformed regarding the rug doctor , and indeed the ninja, so he is doing the right thing by asking, surly he does not need comments that are aimed at taking the p*ss.
I know when I first looked into c/c ,naive , indeed I was , and Knowing the difference between different extractors and their capabilaties was frightening, how ever a little research and a vast amount assistance, I managed. So many tks to those who helped,
it may be obvious to seasoned c/c , but not to a newbie, help them , dont dishearten them.
Good luck Marley, and I suggest any number of other machines may well fit your bill.
