If the “not being as convenient” comment is directed towards Spin Cleans, I would claim it’s just the opposite. They certainly take up less space to store and to use and don’t create the noise as would be so with a “de-luxe” RCM.
I have observed RCM’s in operation several times at local shops offering a record cleaning service. Although I have not timed the process, cleaning a disc via RCM took longer than it takes me to clean one in a Spin Clean.
Twice when I’ve visited a particular used record store, the person behind the counter was engaged in cleaning LP’s with a Spin Clean. At the same time he was able to converse with customers and answer the phone. The Spin Clean while in use was placed on the counter top occupying not much space at all.
To date, I have cleaned somewhere between 4000 and 5000 records with a Spin Clean. It sits on a shelf when not in use, takes a couple of minutes to setup and the cleaning process takes less than a minute per record.
I let them air dry so no additional effort what so ever. I pass the intervening time engaged in other tasks such as repairing album jackets, whiling it away watching Netflix or I just go to bed. The clean, dry records can be inserted in their jackets the next day.
I’ve duplicated Spin Clean’s fluid so by now, cost of cleaning is literally next to nothing. Even after cleaning as many records as I have, the original brushes are still serviceable and original rollers in good condition.
I purchased replacement brushes along with the Spin Clean eight or nine years ago and do not anticipate any additional expense.
Record cleaning cannot get more convenient than that in my opinion.
