^^ Mine is a small one designed for home use or small, low-volume business use. I used to work at a 5-star restaurant, and this one is better than the one I used there. But that was 25 years ago, and I'm guessing that the durability of that one would be better than mine. (Stuff isn't made like it used to be.)
Flushing only takes about 2~3 seconds though. I'm only turning on the steam. It's not a large, commercial system. So, it sounds like they're not very comparable there. Kind of like a Mack truck and a Chevy pickup.
But I've never been able to get a really good, very thick froth - certainly not like whipped cream. I can get it pretty good, but not like I've had in some cafes. I suppose I just kind of suck at it. Dunno. Could be the system. Could be me.
I might pick up a small carton of skim milk to see if I can manage to get that "whipped cream" texture. I've only been able to get it "thick", but not thick enough to draw in or mold.
