To see the tangling ability of a Pulsamatic, you really have to see a Unimatic in action as well and compare the two. Even though I've had limited experience with one, it didn't seem to tangle as much. At the Convention, I threw a couple of loads in the WD-57 Pulsamatic that did have a circulator column you could add soap to (with a spring-loaded cap), and while it agitated twice as fast, the stroke length was only 3/4". The clothes did roll faster than they would in an oscillating-agitator machine, but still not as fast as a Unimatic. I didn't notice any tangling when both were finished and I pulled them out. Robert then switched to the BOL circulator column (the black agitator that resembles something out of the Jetsons) the next day it was ran, with a full load as well if I'm not mistaken. Everything moved with a steady roll that was much slower than the Unimatic so that lessened the possibility of tangling. I didn't see *that* particular finished load, but considering that the other two weren't in knotted ropes, it wouldn't surprise me if that one wasn't either.
I haven't had an "escape rope" from washing in the WO-65-2 Unimatic yet, so for those that don't load it in a circular fashion and use the "four corners" technique, heavy tangling is pretty much a non-issue in my opinion. I do admit I've had some lightly tangled loads, but they were extremely easy to "unwind", so to speak.
Robert, what have you found from washing in the Pulsamatics? I'd be interested to know if one circulator column tangles more than the other; isn't the "ring pattern" slightly different on the Super circulator column versus the Deluxe?
