Ultrasonic Cleaning Machine

@oldaudiophile, 

Watching the video, the rotation appears to be about 6-rpm, and from this site, Knosti Disco-Antistat Ultrasonic 2.0 | MUSIC STORE professional, the power supply is 12V & 3A = 36-watts as you indicate.  The Knosti appears to be following in the footsteps of the Audiodesk_Pro which while a UT device, the Audiodesk_Pro_Manual-2017.pdf is 4.5-L with very low power (90W) for the volume, both apply brushes to mechanically clean the record surface.

Both units have enough power for cavitation (does not take much power to produce cavitation at low kHz), but the cavitation intensity (which does the deep cleaning) is low, with a lot of cleaning being done by the fixed brushes for the Knosti or the rotating roller-brushes for the Audiodesk.  The use of brushes mitigates the weakness of UT to remove surface fingerprints w/o use of enough cleaning agent in a concentration to warrant a rinse. 

Thanks for chiming in on this one!

Judging from a close-up look at Knosti's switching adapter plug, I think 36W is the maximum power output.  Seems pretty anemic.  I, also, noticed that the rotational speed seemed quite fast and there doesn't seem to be any way to modulate this, as well as no heat selection capability.  The machine probably relies on whatever heat is generated by the ultrasonic action.  I found The Audiophile Man review informative, too, as well as this YouTube review:

Here is the official German site for the Knosti Disco-Antistat Ultrasonic 2.0 record cleaning machine - Knosti Disco-Antistat Ultrasonic 2.0 | Ultrasonic cleaner for vinyl records and here is a good review of the unit with lots of photos - DISCO-ANTISTAT ULTRASONIC FROM KNOSTI - The Audiophile Man.

The unit operating frequency is 46kHz vs the HG 40kHz vs the DG 120kHz.  35kHz (such as the Kirmuss) to as high as 50kHz is all for general cleaning.  The DG 120-kHz targets much smaller particles and thin films that has some advantages over the lower kHz machines along with reduced noise. 

There is no mention of the Knosti power, but with only 1-L fluid volume and the above review made no mention of heat, it's power cannot be extreme.  As the review shows, it has an easily accessible pump and small filter/strainer (of no known micron-size) that operates during the UT process.  The flow rate is not specified nor is the record spin speed specified.  As the review shows the UT is augmented by brushes.  There is no operators manual available on the web to download.

Unlike the HG or DG, there appears to easy option to add a rinse cycle; although I suspect that the record holder is similar to their manual cleaning units such as Disco-Antistat Generation II PLUS Vinyl Record Washer – Knosti which could make a rinse step relatively easy.

The record must first be assembled in the record holder, so this adds two steps - one to assemble and one to dissemble and as others have noted no drying step.  So, compared to the DG and HG, the Knosti is not as convenient.

What a foobar website. Every "Learn More" link about their products redirects to a dealer login page. Fail!

I have a Degritter II and it is well worth the money, IMO. But I have 5k LPs so it's a reasonable investment. 

Personally, I wouldn't want a US cleaner that doesn't also dry after washing. I have been down that wet road and it's bumpy and not fun.

IMO, HumminGuru NOVA is a better choice as it offers drying cycle as well.
