John how is your 4 vac system going. Whats the longest run you use it from? Do you use it from the van? what are the dry times like in comparison with just the 2 vacs?
Hey Robin , It works really well and i find myself using it more and more . It was suppose to be to reach upstairs form a door with good power but have been using it now at short lengths , the extra power is addictive as it seems to clean faster ,better and speed up the drying ( i would hate to put a time on that as ambient temp , carpet type and other things are variable) , i always use it with my inline heater also . Length wise i have 100ft of 2" and 75' 1.5 on the van , itend to use a 15ft whip for convenience a lot . but sometimes i attach straight to the 2" with an adapter . At 100ft it seems no different than at 25 . How it performs at 200' i have little interest as i never would use it that way .
The extra vacs add 100+cfm to the strong suction it already has , in practical terms that makes the wand whistle insted of hum at long hose distant also When u put a lift gauge on the four vac setup u see the needle rise much faster than the two vacs in series ... so even though they both have the same lift , the faster rise give a more snappy instant grab on the carpet which is desirable i believe .
No i have never used it from the van ... i just Take the Enforcer out , i had it out side in hail and snow all winter never troubles it , i bring the lot inside occasionally if the place is empty .
