HumminGuru ultrasonic RCM FTW! (The one from Kickstarter)

Also, it looks like Juno are selling the cleaner on its own, not including the 10” and 7” adapters. I wonder others here have gone for the basic or the bundled package?


Ah, that’s excellent customer service then, and perhaps buying direct is the best way to go if they are that focused on taking care of their buyers.

I had questions and received very quickly a response. I feel they are very serious and want to keep a perfect reputation.


What I don’t see is any documented experience here with really grimey second discs. You know, the ones that reek of tobacco, have mysterious sticky patches like someone pawed them after eating a peanut butter and jelly sandwich. My current cleaning fluid and submerged horse hair brush system gets those discs coming up in mint condition.

I’d be interested to hear how the HumminGuru deals with something really foul from a bargain bin.

Sorry can’t help there, I don’t have any like that and likely never will

Ah, i have just cleaned some right dirty stuff for a mate. You know, the stuff that has rolled around carpets.
When faced with such stuff i give them 5 mins of cleaning, change the water, then another 5 mins of clean plus 10 mins of drying. The first lot of water was a bit yellow, the second lot less so. But the vinyl was physically clean and sounded clean.
So, yes it works and works well.
Mine has now done 2000 cleans since i had it? And still using the original filter pieces. I wash them out each time, but they are dirty now.


Thanks for all the good info in this thread.

Anyone tried or heard of experiences with the Knosti - Disco ultrasonic cleaner?


I just see it’s 3 times more expensive. But have no idea if it’s better or not.

There seems to be more and more alternatives when it comes to ultrasonic cleaners, and with very different price tags. Still hard to determine what difference there is in build quality and cleaning results.

For reliability in the long term it’s difficult to know for now, members have the Humminguru since maybe 6 months only here.
Will it last 5, 6 years or more ?

As you said there are very different prices. From 400 euros to 6k. But the Chinese costs of manufacturing are much lower too. So in Europe such machine would cost certainly 3 times more.

I would be interesting to know how they compare to each other. But such reviews don’t exist.
Like with RCM machines, how to know that Project RCM , 500 euros, is lesser performing or not vs the Clearaudio at 5k?

After 3 weeks of using the HG, I am very satisfied. I feel that using some cleaning fluids ameliorates a bit the cleaning.
For some problematic lps I put some Art du Son cleaning fluid on both faces, then do select a manual long cleaning process ( around 5 minutes) then put the automatic process to end and dry.
I ordered today the Degritter cleaning fluid that Degritter ultrasonic recommends for a better cleaning.
Bought from Analogue Seduction, less expensive vs Amazon. Will share.



Will be intrested to hear the results. Personally i just use tap ( softened) water and a hint of dishwasher rinse aid.
Nice shiny clean lps here.

The only problem I have with distilled water is that it’s much more expensive online. In a supermarket, I pay 2,5 euros for 20 l . On Amazon, it’s 15 euros with shipping. Not a big problem, I buy 2l per week that I carry in my bag when on the way to home.

Hah, let me know when it turns up! I’ve had a bottle of that on order with them for months! I don’t know, ordering wait times for cleaning fluid really leaves something to be desired these days :wink:

I’m the mean time, distilled water still working fine for me :slight_smile:

Is the supermarket sourced water distilled, or deionised?

I read somewhere that the water our Miele heat pump dryer collects is distilled by definition; if I can ground truth that, a RCM like this could be a good proposition😎Normally it gets poured on the garden!

In theory it sort of is. However, there will be carryover products from the clothes that have been washed such as detergents and even some fluff.
A faily risk free method is to taste a bit. It should taste of nothing/smell of nothing.

In some countries like mine they sell it in pharmacy/drug stores.

Ordered from Analogue seduction?

There can be different levels of purity for distilled water depending on the process and materials used. If the rig is anything but spotless non corrosive material it results in a lower grade than that made with glass condensers.

Hence distilled water at the filling station is cheaper than distilled water sold online for lab use. It isn’t the same thing.

Yes, part of a larger order (almost including a Technics 1200G :wink: ) the other pieces all ok, just that item not in stock.
