Yes, the Loricraft does work on the same thread principle as the KM. The original concept came from an editor at 'Gramophone' magazine back in the 1960's.
The LC also outcleans a VPI, much as you described for your KM. I believe your KM is even better though. Isn't your thread mechanically pulled through the waste tube? The Loricraft doesn't do that. With a Loricraft you have to give the spool a little twist after each vacuum sweep to help the vacuum pull the thread along.
Nice acquisition. The improvement in lowered noise floor with this vacuuming system is very noticeable, as is the ability to get ramped lead-in grooves cleaner.
