Well there is a $4000 false economy right there!! No vaccuum, just fan dried .
In terms of a business buying one of those machines it becomes part of the PR " we use only the best, $4000 cleaning machines from KLAudio ! " because it builds on the PR and money alreadu spend promoting the KL Audio product and gaining a "reputation". Sadly that's the reality of a consumer market - they like to see brands with established reputations rather than any unknown make of equipment being used on their precious vinyl.
Aside from that though, as a product in itself.. I see that $4000 machine as the snake oil the thread's title is calling on.
Here, for example, is someone back in 2010 (before these multi-thousand dollar cleaners came to market) just dipping their vinyl in a regular $300 ultrasonic cleaner bath to suplement their normal vinyl cleaning method of a Knosti DiscoAntistat: http://forums.stevehoffman.tv/thread...ecords.235771/
In 2008 a Norwegian guy on DIYAudio.com came up with the idea of making an ultrasonic vinyl cleaner with the same rotary method - again long before there were any commercial products: http://www.diyaudio.com/forums/analo...d-cleaner.html
So a $200 - $300 ultrasonic cleaner is taken, fitted with a motor and a fan or two and then encased in a fancy box with thick, styled ali cladding... and suddenly it is a $4000 cleaner with folks like the guy in the video reacting by saying "fantastic invention!". I see that as pulling the wool over people's eyes and therefore akin to being Snake Oil.
What's the price to the UK? If a private individual were to buy one, I'd say it were a case of a fool and his money being easily parted.
