The most important factor in me switching from
butler to the
hydramaster cds was local support. Every time I needed something from
butler no matter how small the part it cost at least $85 to ship, plus it took at least 4 days. My business is growing and I wanted parts supply to be on the west coast, and tech support available after 1pm my time.
I definitely notice how much less volume of air my
cds flows on an open hose, but lift capability is higher. I am getting the same dry times, or slightly better.
Support has been really great, but both my machines have had a lot more trouble than I expected out of brand new machines. The transfer pumps in both hydracradles failed, both machines randomly lose speed control and idle down to 500 rpm, and one of the pump outs has already worn out an impeller( that was my fault).
