Monitor is the brand name. They made a few different models, all compact sized, i think. This one is compact, would love to see a money shot of the inside.
Put as one who spent a part of last night putting several sheets through a hand mangle (the Miele couldn't get the load balanced property to spin without beating itself to death), am here to tell you wouldn't touch any manual wringer washer. *LOL*
If one is going to have a wringer machine the thing should have a motor. Suppose for small items it isn't an issue; but with larger things you need to control how things are fed which is easier if you aren't also cranking the mangle with other hand.
