Kirmuss uses a pretty ubiquitous ultrasonic bath* with the addition of a proprietary spinner that uses multiple slots rather than a rotisserie like the Vinyl Stack. He also uses a fluid that he claims removes all sorts of nasties left over from prior bad cleanings. I haven’t used it- there’s a fair amount of anecdotal information on the Hoffman forum about having to repeatedly clean to remove a paste-like residue that Kirmuss claims is the result of built-up contamination. Judging from those comments, which you can read yourself, it’s a pretty time intensive process.
I don’t have an issue with his introducing a low cost entry into the ultrasonic sweepstakes, but some of his claims are, well, a bit extravagant.
If you can ante up for an Elma, another fine piece of German engineering (sorry about your MB, @tomic601 - my favorite was a ’69 300 6.3- sort of a short wheelbase 600 with oodles of power), you’ll spend more but get a better quality US bath. Add a water recirculation filtering system for less than 100 dollars and the Vinyl Stack and you are in business for more than the Kirmuss but still far less than the AD or KL.
*One claim he does make that I agree with is the position of the transducers on the bottom of the tank, rather than at the sides; given how wave propagation occurs, the LPs act as baffles if the transducers are at the sides of the machine.
