Seems like multiple sites have a different number when it comes to measuring cfms and lift on these vac motors. How much of a difference would the quad 5.7 have vs dual 6.6s really have.
Quad 5.7 with auto dump wont allow a pressure pump without a 3rd cord .. Im wondering if Im giving up much vac power - (cfm or lift) if I go with a machine that has dual 6.6s and a 500psi pump and auto dump on 2 cords.
Ive heard when the cfm and lift numbers are close it makes a perfect sucking machine.
The Goliath has dual 5.7 in series x 2 running in parallel. Says 250 cfms and 170'' of lift. Which sounds great. The Clean Storm has dual 6.6s, which they say are in parallel but I see a pic where it looks like its in series, that offers 170cfms and 215'' of lift - which can also run a 500psi pump and pump out on 2 cords.
Im willing to go with a 3rd cord to power a separate pump (water otter) if the end result is significant.
Ive also noticed when they say the cfm on 1 vac motor is __ cfms they usually double the cfms when 2 of the same are used but when stating the lift .. it has been stated with the same numbers.
So increase cfms as you increase vac motors but lift usually hovers around the same number and only fluxuates if your choice is series or parallel and or size of vac motor of course?
Hard to follow since different sites show different numbers on same vac motors !!
Im looking to work with long hose runs .. 100-150ft maybe 200 .. commercial carpet !!
