Best ultrasonic lp cleaner in 2020 and what surfactant best?

I have the  Kirmuss Ultrasonic RCM and all you do press the clean button and it cleans 3 records the in 5 minutes.  There are no steps. 

All ultrasonic cleaning systems, whether for records, jewelry, medical instruments or eyeglasses require that the initial tank of water be degassed. That is a given.  The Kirmuss makes it easy by having a separate degas button.  Push the button and the water is degassed.  Once degassed, you are ready to go.

At some point yes, you have to change the water as dirt and debris collect, but that is the nature of any record cleaning system.  The water gets dirty and you need to change it at some point.

I have been impressed by the degree to which ultrasonic cleaners work relative to other record cleaning systems and the nice thing about it they are automatic.  I then dry the record with my Nitty Gritty record vacuum and you are good to go.

@tablejockey The Spin Clean works fine, I have one of those also, but you still have to dry the record whether using the Spin Clean or whatever.  So your point that the extra step of drying the record  further adds to the complexity is moot.  The post cleaning steps described with the Kirmuss have to do with restoration of older records.  Why bother? For the most part if you just want to clean your records, you push the button and dry them.  Simple as that.

My only issue with the Spin Clean is the sponges do not last very long once they dry out.  If you leave them in solution, the solution gets grows fungus within a few days depending on ambient temperature.  Of course, the same is true with any record cleaning system that has a reservoir.
