"I just wanted to let you guys know that i love this unit! I've never had any issues with suction, which i find especially amazing since i'm used to working with truck mounts which are "rated" for 16,000 cfm. I can't thank you enough for building such a high quality machine. The mobility of this vacuum is unparalleled. In fact, i just finished cleaning the ductwork for a 26,000 sq ft school. sure i had to empty the filter a couple of times, but i'd take that over high maintenance costs any day.
Thank you again."
