Why so few record cleaners for sale?

It seems like a lot of people are getting out of the record game so I thought I would take a look for a record cleaner. There are some of the cheap ones for sale, but I thought there would be more. Do the people that have them use them, or are they collecting dust in the basement or garage???

Do people have CD cleaners too? I've never seen one, so I'm curious. Is there are market for a product like that?
