Here is a transcription, if you prefer to read instead:
“A very common question we get asked is, “How often should I clean my carpet?” Well, the answer is that just in order to maintain the warranty on your carpet, you have to have the carpet cleaned every 18 to 24 months, depending on the manufacturer. Some require 18, some 24. You definitely want to have that done with hot water extraction. That’s the method that we recommend here, and I would highly recommend that you don’t do it yourself. If you decide you want to, that’s OK, just do it between the times you get it professionally cleaned. Just remember: the two biggest enemies to carpet are dirt and homeowners who clean their own carpet.”
