I hope you take my advice and keep it. Just remember to walk away from the hose on those big rooms. If you don't use it every week, don't worry, you'll use it more in the future if you're chasing bigger jobs.
And I learned something new with my zipper last week. On that big room posted at that church, did you try going in different directions? (forward backwards and left to right?) The only reason I'm asking is I did that on my last job and it extracted water differently. When I pushed it left to right, I could barely see any water on the dry passes, but when I went forward and backwards, it showed twice as much water being extracted on the dry passes.
@Mark Saiger , what's your thoughts? Did it perform better on the wet passes or perform better on the dry passes going in the different directions due to the nap of the commercial carpet? Has anyone else noticed that?
