Construction Dust Cleaned Up

I am really excited today.  I was just talking with my dad who owns a construction firm.  He was telling me that a salesperson just visited him the previous day and he was telling my dad about construction site vacuum equipment.  I have worked for my dad in the past during school and during summers while I was at college.  I was usually responsible for all of the clean up after the jobs were done.  So, the idea of having some vacuum equipment to help with the huge job of getting all of the construction dust cleaned up is a huge deal for me because I know how much it will help get the job done.
