Pawlowski6132, it would have to be the vacuum. Everything else is largely the same in most instances. Your are using the steam, but most merely apply the cleaner and scrub and then remove the fluid or dry. I suppose some machines have applicators and some merely have you spread the cleaner around, but I think that is minor.
I think the benefits of the Loricraft and Keith Mooks is the vacuum being at one point on the record and moving outward across the record while riding on a string. You can actually hear the liquid being slurped off.
Audiofeil, you had me going as your comments are so close to what one hears too often both here and on AA.
I have actually seen microscope pictures of grooves using the Loricraft and other machines, and I have heard of the tests of cleaners removing some vinyl. These were by the manufacturer, however. I know of no such work by any reviewers.
