I can find common ground thererwcarpet said:Ken Snow said:The 650 sq ft with 80 gallons seems like a lot, but without knowing soil conditions etc., it is really hard to judge. I cleaned 12-1400 sq ft of carpet in my condo in the same general manner using only about 25-30 gallons. One direction triggering is not as effective as 2 to me.
I'm sidin' with Ken here......power on both directions. I run a 59 blower so vac isn't a problem. Just make the forward stroke quick and don't dic around. Slow down on the back stroke to clean and extract, then go back for a dry stroke.
Simple as that.
