What you should know is, that the higher the ultrasonic frequency, the smaller the exploding bubbles, but the weaker their exploding energy and the opposite for lower ultrasonic frequency.
Smaller bubbles mean, they go deeper into the groove and clean the grooves more thoroughly but can’t remove harder, less loose dirt there. Larger bubbles mean, they can remove harder, sticky dirt better, but rather on the top of the grooves than deep in them.
Cheaper cleaners have lower frequencies. Kirmuss for example recommends heavy manual cleaning with microfiber cloths accompanying the ultrasonic cleaning process (probably because only that ensures proper overall results). The same for also still too low frequency cleaners like the Glaess, which additionally uses circulating kind of brushes inside which help, but still don’t go deep into the grooves.
More expensive cleaners with high frequency and small bubbles like the Degritter (I think it’s the only higher frequency cleaner except custom made’s currently) clean deeper in the grooves but can’t properly clean older records with somehow more baken-in dirt.
Every cleaner, no matter if expensive or cheap ultrasonic or cheap vacuum cleaners are good enough for new records. For new records, no one needs a cleaner over 800$. The only problem are older, used records, originals etc. In my experience they can be best cleaned with the Hannl Mera professional Vacuum cleaner using a rotating brush (which is also expensive).
Due to the limitations of small or big bubble ultrasonic cleaners, Degritter is shortly offering the first ultrasonic cleaner using two different frequencies to cover both, small bubbles to get deep into the grooves and large ones to provide the necessary energy to remove more heavy dirt. This cleaner will probably be well over 4k I guess.
So if you mostly just clean newly bought records, it doesn’t really matter for cleaning results, which cleaner you choose, it’s rather a convenience decision.
