The HumminGuru is one of the most talked-about record cleaners of recent years because it brought ultrasonic cleaning down to a price that ordinary collectors could consider. Ultrasonic machines used to be a luxury for audiophiles and archives. Now there is a compact desktop machine that cleans and dries a record in a few minutes with almost no effort. That does not mean everybody needs one. This guide covers what the HumminGuru does, what owners like and dislike, what it costs to run, and how to decide whether it is worth it for your collection.

What the HumminGuru is

The HumminGuru HG01 is a compact ultrasonic record cleaner. According to its listing and manual, it uses 40 kHz ultrasonic cleaning in a tank of about 350 ml of distilled water and accepts 7, 10 and 12-inch records. You lower the record into the slot, choose a mode, and the machine rotates the record through the water while ultrasonic transducers loosen dirt. A built-in fan then dries it. The manual describes a quick cycle of two minutes cleaning plus five minutes drying, and a longer cleaning option of five minutes.

What owners like

• No contact with the groove. No brushes press grit along the surface, which is one of the main arguments for ultrasonic cleaning.
• Low effort. Insert, press a button, wait. There is no scrubbing or hand drying.
• Small size. It fits on a shelf or desk and does not need a dedicated cleaning station.
• Consistent results. Every record gets the same treatment, so results do not depend on technique.

Owner threads on r/vinyl and r/humminguru often mention that records sound quieter after cleaning, especially used records with years of surface grime. That said, people are clear that it removes dirt, not damage.

What owners dislike

• The small tank. The water gets dirty faster during a big session of grimy records, so you change it more often.
• One record at a time. Cleaning a large backlog takes a while, because each record is a separate cycle.
• Maintenance. You need to empty and refill the tank, rinse the filter and keep the machine clean.
• Very dirty records. Some owners pre-wash filthy thrift-store finds in a manual washer to keep the HumminGuru's water cleaner.

Running costs

The main ongoing cost is distilled water, which is cheap but needs to be bought or made. HumminGuru's FAQ suggests warm distilled water and regular filter rinsing; it does not set a fixed number of records per tank. Owners tend to change the water when it looks cloudy or every few days of regular use. Some add a small amount of ultrasonic-safe surfactant. If you do, follow the manufacturer's guidance, because foaming additives can be a problem in ultrasonic tanks. Our guide to distilled water vs record cleaning fluid explains the trade-offs.

HumminGuru vs a manual washer

The most common alternative is a manual record washer such as the Spin-Clean, where you turn the record by hand through a basin of fluid with brushes on both sides. It costs much less and works well. The trade-off is effort and drying: you need to dry each record with a cloth or rack.

Specs are from manufacturer and retailer listings and can change between versions; check the listing before you buy. We don't show prices because they change often; the button shows the current price on Amazon.

HumminGuru vs premium ultrasonic machines

At the other end are machines like the Degritter, which offer a higher ultrasonic frequency, a much larger tank and more programmes, at a much higher price. They suit heavy users. For most home collectors, the HumminGuru covers the same core job. See our HumminGuru vs Degritter comparison.

Who it is worth it for

It is probably worth it if:

• You buy used records from shops, fairs or thrift stores.
• You have a few hundred records, or plan to.
• You dislike manual scrubbing and hand drying.
• You want consistent results with little effort.

It is probably not worth it yet if:

• You own a small number of mostly new records.
• You rarely hear surface noise after a dry brush.
• You would rather spend the money on records, a better stylus, or sleeves.

Getting the best results

1. Brush loose dust off the record first with a carbon fibre brush.
2. Use distilled water at the temperature range the manual suggests.
3. Use the longer cycle for dirty used records and the quick cycle for new or lightly dusty ones.
4. Change the water when it starts to look cloudy.
5. Put cleaned records into new inner sleeves so old dirt is not transferred back.
6. Clean your stylus too, so you do not put old dirt back into clean grooves.

What it will not fix

No cleaner can fix scratches, worn grooves, pressing defects or warps. If a record crackles in the same place every rotation after cleaning, it is probably a physical mark. Background crackle that changes from play to play is more often static or a dirty stylus. Our guide to crackle after cleaning explains how to diagnose it.

A typical cleaning session

Here is what using the HumminGuru tends to look like in practice. You fill the tank with distilled water, ideally slightly warm as the FAQ suggests, and slot it into the machine. You brush the first record to remove loose dust, lower it into the slot, and start the quick cycle. While it cleans and dries, you can sleeve the previous record and pull out the next one. After a batch of records, you check the water. If it has turned cloudy or you can see particles, you empty it, rinse the tank and filter, and refill.

The rhythm is relaxed, but it is not instant. If you have a backlog of a few hundred records, plan to work through it over several sessions rather than one afternoon. Many owners clean each new purchase as it arrives and work through older records gradually.

Common mistakes

• Running filthy records first. Mud and heavy grime quickly cloud a small tank. Pre-wash very dirty records in a manual washer, or clean them last.
• Forgetting the filter. A clogged filter reduces circulation. Rinse it regularly as the manual and FAQ describe.
• Using tap or bottled mineral water. Minerals can leave deposits. Use distilled water.
• Sleeving records in their old dirty sleeves. Old paper sleeves shed fibres and hold dust. Use fresh inner sleeves after cleaning.
• Expecting it to fix everything. Clicks from scratches remain after any clean.

Is it worth it compared with paying for cleaning?

Some record shops and services offer ultrasonic cleaning per record. If you only have a handful of very valuable or very dirty records, paying a shop for those few may cost less than buying a machine. If you buy used records every month, owning a machine becomes the cheaper and more convenient option over time. Owners on r/humminguru often describe this exact calculation when explaining why they bought one.

Our verdict

For a collector who buys used records regularly or who already washes records by hand and finds it tedious, the HumminGuru is a sensible purchase that makes cleaning easy enough that you actually do it. For someone with a small collection of mostly new records, it is a nice-to-have rather than a necessity. Start with a brush and good sleeves, and come back to ultrasonic cleaning when your collection or your second-hand buying grows.

Where it should live

Put the machine on a stable, level surface away from the turntable itself, so that drips and fan noise do not bother your listening. Leave space behind it for air to move during drying, and keep a towel nearby for emptying the tank.

It is also worth thinking about noise. Like any ultrasonic machine with a drying fan, it makes some sound while it runs. Most owners describe it as tolerable, but you will not want it running on the same shelf as the turntable while you listen to a quiet record. A separate table or a kitchen counter works well, especially because you will be handling water.

FAQ

The manual describes a quick automatic cycle of about seven minutes, two minutes cleaning and five minutes drying, plus a longer cleaning mode.

Can it clean 7-inch singles?

Yes. The listing states it accepts 7, 10 and 12-inch records.

Will it get the label wet?

The machine is designed so the label stays out of the water when used correctly. Insert records as the manual directs.
