Vinyl cleaning - Ultrasonic vs. Walker products

I am using Walker Prelude for some time now and even though considerable cleaning time is required, especially first time cleaning, it it does a great job and lp's stay clean for a long period of playing time.
So i do about 10 lp's per cleaning session, as work is done manually on a DIY rotating platform.
The Audioquest super conductive anti static brush is doing a nice job prior playing.

Thanks for all the suggestions. My budget is less than $1K, have about 200 to do. Some are in good shape and other are quite dirty, to the point I would not consider playing even after using my discwasher several times.

Wow, Audio desk is $4K... Would the VPI 16.5 be the next choice? From what I have read, ultrasonic is the way to go?

I own the Okki Nokki, about $500 and it does an excellent job for a vacum cleaner. The VPI is also within your budget. The motor on the VPI is a little louder if that matters to you.

Thanks, I appreciate your recommendation.
