Why are record cleaners so expensive?

I wonder if anyone buys the really good ultrasonic machines and then starts a record cleaning service. Assuming the devices are durable and have low maintenance over time if used heavily.

I mostly buy used vinyl these days and I only clean dirty records thoroughly once. Once properly cleaned, all I do is use a carbon fibre brush to quickly remove any newly settled dust before playing. A record cleaning service is something I might be interested in using.

@cleeds To each his own. Thank you for clarifying some of the economical and mechanical reasons behind my original question.

And yes, as you condescendingly point out, when "that little holiday is over" all I'll have is "photos and memories." However, I find those to be worth far more than any material item I've ever had.

@mapman You put things in perspective - as you usually do.

My Spin Clean also beeps when a record is done, and I have no idea where the beep is coming from…weird...

Perhaps the question, reframed, is "I have a modest record cleaning system (X and Y) that I’m happy with, but wonder if those expensive record cleaning machines are really that much better and worth the money?"
A little less antagonistic, particularly since you seem to acknowledge that one can spend money on handcrafted or bespoke items that have importance to the buyer.
Most folks are allergic to hype, and I’m not going to tell you that veils were lifted or the orchestra was in the room. What I will tell you is that I’ve spent a fair amount of time and money messing around with various record cleaning methods, machines and techniques and not only have a lot of records, but some very valuable ones. I can get a record very clean using a basic VPI. But some records, particularly older records that have been exposed to who knows what, require multiple cleanings, and in my experience, multiple approaches. That’s where the combo of a couple different devices, including ultrasonic, starts to pay off.
If you don’t think it’s silly to spend money on a suit, a fishing rod or a vacation, why would you think it’s crazy to spend 3 grand on an RCM? (which, as noted, you don’t have to do if you are willing to go the semi-DIY route).
