When I was 18 years old. I took the astro cleaner
I took the astro cleaner to clean carpets in a 6 story bank. I made a vacuum manifold to run 5 vacuum hoses. We pulled the hose up the stairwell and down the halls about 250 ft each, and we started cleaning, it had more than enough vacuum power with a #8 BLOWER. I had 2 guys per floor, and as we cleaned we would pull the hose back to the stairwell. Then the guy on the 3rd floor came up the elevator, and said the door was blocked with vacuum hose. Have you ever felt like a big dumbass, well I did that day. We took the elevator down to the first floor, and it was the biggest mess you've ever seen. Vacuum hose filled the stairwell for 3 floors.
