Richard the hi range is awesome. i believe that meyer conservatively rates their equipment because the zephyr is about twice the vacuum of the porta
vac.The lift is awesome we can pull anything that fits into the hose pieces of bricks, large nails, wood pieces, my cordless drill

We clean the vacuum collector box about every 4-6 months, we take the bag filters out turn them inside out and blow them
out.About once a year we will wash the bags at a commercial laundry. Its easy to clean the bags and collection
box.This setup makes the porta vac look like a toy i dont think you could go
wrong.The hi range is awesome and great for large commercial jobs.I knew a guy with one and he would run 300-400' of hose all the
time.The truth is i dont see any reason to upgrade we do residential, commercial, industrial, healthcare , cleanrooms etc every day and really this setup works
great.We also have a 5000 cfm and 3200 cfm electric hepa vacs for places where this truck wont reach.
