Jtimothya, only the single cleaning fluid they provide can be used and reused. This fluid is drained off and goes into a holding tank in the bottom of the machine. It is evaporated off the record with fans, not vacuumed. Nevertheless you do not hear residue after cleaning.
One of the disturbing findings I had was that using it after I had cleaned records with the Walker Prelude and vacuumed it with the Delrin tubed VPI record cleaner. It was improved greatly. Also doing the reverse, greatly improved the sound??? I am not about to clean all of my records with two different machines.
The Audio Desk Vinyl Cleaner was vastly more convenient. If you have it in another room, you can listen to music a go to it to remove a cleaned record after about five minutes.
