At a Glance
VEVOR 15L 360W Ultrasonic Cleaner with Timer and Heater
↓ See why we picked itVEVOR 15L-Class Ultrasonic Parts Cleaner, 40kHz
↓ See why we picked itA 15 L ultrasonic cleaner is a different animal from the little jewelry tubs most people picture. It has room for a full set of kitchen hardware, a lawn mower carburetor, a tray of hobby parts or a bundle of watch bands, and it lets you clean them in one batch instead of three. The catch is that these machines are heavy, need a real surface to sit on and are built around heaters and 360W of ultrasonic power, so a few details decide whether one is pleasant or a chore to own.
We evaluated six 15 L models based on product specs and buyer feedback, looking at ultrasonic power, heater wattage, special modes, handles, basket and tank construction, and how simple the controls are. Five are VEVOR variants with real differences in power and features, and one is a CREWORKS with a larger heater and a gentle mode. Many of the listings share similar marketing language, so we kept to the numbers that actually separate them.
Use the picks as a starting point, then work through the buying criteria and decision tables to match a machine to your workload and your bench space.
6 Criteria to Look For Before Buying a 15L Ultrasonic Cleaner
Key buying criteria so you get the right fit the first time.
Ultrasonic power versus tank size
Total wattage has to be spread over a lot of water, so a 15 L tank needs far more power than a 600 ml tub to clean the same way. Look for roughly 300W or more of ultrasonic output if you plan to clean grease-heavy parts, and treat anything much lower as a light-duty machine. In this lineup the CREWORKS, the degas-and-gentle VEVOR, the six-transducer VEVOR and the timer-and-heater VEVOR are all 360W, while the VEVOR 15L Professional is 240W. That 120W gap is the difference between one cycle and two on a stubborn load.
Heater wattage and control
A heater loosens grease and speeds cleaning, but heater size changes how long a cold tank takes to reach temperature. A larger heater is better for batch work, and 400W or more is a sensible target for 15 L. The CREWORKS lists a 450W heater and the six-transducer VEVOR lists 400W, while the other VEVORs do not state a wattage in the text we had. All the picks run from 0 to 80°C or 32 to 176°F, so check that your items can handle the heat before you raise the dial.
Degas and gentle modes
Degassing clears dissolved air so cavitation can work, and a gentle mode lowers the output so thin or delicate items are not stressed. These two features matter most if your load is mixed, such as eyeglass frames next to hardware. Only the CREWORKS 15L and the VEVOR 15L Sonic Cleaner list them. The CREWORKS gentle mode halves the ultrasonic power, which is a useful rule of thumb for a safer clean. If you only clean rugged metal, you can live without them.
Weight, handles and draining
Fifteen litres of water weighs roughly 15 kg before the machine itself, so handling is a real ownership issue, especially if you have wrists or shoulders that tire. Plan to empty most of the water before moving the unit, and place it on a stable surface close to a sink. The VEVOR 15L Sonic Cleaner and the VEVOR with the timer and heater both mention a portable handle and drainage, the CREWORKS has inset handles and a top cover, and the 15L-class VEVOR has side handles. Any of these beats a tank with no way to lift or drain it.
Tank and workpiece dimensions
Capacity in litres does not tell you whether a long item will fit. Check the interior footprint and the maximum workpiece size, and remember you need to keep items in the basket, not on the tank floor. The six-transducer VEVOR publishes a 13 x 11.8 x 5.9 in tank and a 10.6 x 8.7 x 4.1 in workpiece limit, which is the clearest sizing data in this group. The 5.9 inch depth also means tall items must lie flat, so measure your largest part before ordering.
Timer range and cycle habits
Every unit here tops out near 30 minutes, which is a sensible cap because long continuous runs build heat and wear. Short cycles of a few minutes, repeated, clean better than one long run, and they let you check progress. The CREWORKS and the six-transducer VEVOR both state a 30 minute maximum with a digital panel. If you expect to soak items for an hour, plan to restart the timer rather than looking for a longer one, and do not run the tank without liquid.

CREWORKS 15L Digital Ultrasonic Cleaner, 450W Heater
About this pick
The CREWORKS 15L pairs a 360W, 40 kHz ultrasonic section with a 450W heater, the largest heating element listed in this lineup. It adds a degas mode that clears trapped air from the solution and from porous items, and a gentle mode that halves the ultrasonic power for circuit boards, aligners, rings and necklaces. The tank and basket are 304 stainless steel, and the listing describes them as food grade.
The gentle mode is what sets it apart from a plain 15 L tank, because one machine can then handle greasy hardware and more delicate pieces. The timer runs up to 30 minutes and the temperature from 32 to 176°F, so long soaks have to be split into several cycles. The tradeoff is size and heat. A large tank takes time to warm, and heat is the wrong choice for glued parts, plastics and soft stones, so you still need to think before you press start.
Setup is simple: fill, set time and temperature, and lower the basket in. The inset handles and top cover help when you move it, but a full 15 L tank holds around 15 kg of water, so empty it before lifting. Against the VEVOR 15L Sonic Cleaner at 360W it matches the ultrasonic output and adds the bigger heater, while the 240W VEVOR sits a clear step below both.
Best for: Households that want one large machine for greasy hardware and the occasional delicate item.

- Temperature: 32 to 176°F
- Construction: 304 stainless tank and basket
Pros
- +The 450W heater is the largest heating element listed in this group
- +Gentle mode halves ultrasonic power for rings, boards and aligners
- +Degas mode clears trapped air so cavitation works on porous parts
- +Inset handles and a top cover make it easier to shift and keep dust out
Cons

- −Heat is unsuitable for glued, plastic or soft-stone items, so check first
VEVOR 15L Sonic Cleaner with Degas and Gentle Mode
About this pick
This VEVOR runs 360W at 40 kHz and adds the two modes that matter most on a big tank: a degassing mode and a gentle mode. The listing says degassing removes air from the liquid and improves working efficiency by 30 percent, and that dual power settings let you step down for finer work. Heating runs from 0 to 80°C, and both the inner chamber and the basket are 304 stainless steel.
It is the most flexible of the five VEVOR units because it can scale down from a heavy parts clean to something kinder. That helps if your 15 L load includes things like eyeglass frames or circuit boards alongside hardware. The listing does not give a heater wattage or a timer range in the text we had, so those are worth confirming before you buy. As with any large heated tank, hot water is wrong for plastics and glued assemblies.
In daily use the portable handle and drainage feature are the useful details, because dumping 15 L of dirty solution without a drain is awkward. It is a full-size machine that wants a stable bench and a nearby sink. Next to the CREWORKS it matches the 360W output but lacks a stated heater wattage, and against the VEVOR 15L at 240W it has a third more ultrasonic power and the gentle option the 240W unit does not mention.
Best for: Mixed workloads where some items are rugged parts and others need a lighter touch.

- −A full-size 15 L machine needs a sturdy bench and a nearby sink to drain
VEVOR 15L Ultrasonic Cleaner, 360W with 400W Heater
About this pick
This is the VEVOR with the clearest numbers. It uses six 60W transducers for 360W of ultrasonic power at 40 kHz and a 400W heater, and the tank measures 13 x 11.8 x 5.9 inches in 304 stainless steel. The maximum workpiece size is listed as 10.6 x 8.7 x 4.1 inches, which tells you quickly whether a given tray or part will fit.
A digital panel sets time from 0 to 30 minutes and temperature from 0 to 80°C. There is no degas or gentle mode in the listing text, so it is the more traditional, powerful-and-simple machine. That suits hardware, tools and parts, but it is a less careful choice for delicate jewelry or circuit boards than the VEVOR with the gentle mode. The tank is shallow at 5.9 inches, so tall items need to lie flat.
Ownership is straightforward: fill, set the digital panel and run short cycles. The published workpiece limit is the practical advantage, because you can check the size of your biggest tray before ordering. Compared with the CREWORKS at a 450W heater it warms slightly more slowly on paper, and it has the same 360W ultrasonic power as the VEVOR with timer and heater.
Best for: Buyers who want to verify tank and workpiece size before they order.

VEVOR 15L 360W Ultrasonic Cleaner with Timer and Heater
About this pick
This model is the plain 360W option: 40 kHz, a digital timer, a heater adjustable from 0 to 80°C and a stainless basket and chamber. Its listing puts the emphasis on heated cleaning, noting that you can set the temperature for jewelry, watch parts or greasy industrial components. A portable handle and convenient drainage are called out, which matters on a tank this large.
It is a no-surprises machine. You get the same headline ultrasonic power as the CREWORKS and the degas-and-gentle VEVOR, but without the extra modes, and the listing does not state a heater wattage. That makes it the one to choose when you want strong, steady cleaning for hardware and do not plan to switch down for delicate pieces. For fine items you would want the gentle mode on the other two.
Daily ownership is mostly about handling water: fill to the line, set time and temperature, run a few minutes and drain. Because the chamber and basket are stainless, it tolerates rinsing and routine detergent solutions well. Next to the VEVOR 15L at 240W it has half again as much ultrasonic power, and against the six-transducer 360W model it offers the same output with a less detailed spec sheet.
Best for: Hardware, tools and hobby parts where steady power matters more than extra modes.

VEVOR 15L-Class Ultrasonic Parts Cleaner, 40kHz
About this pick
This VEVOR is sold as 15L-class, with 40 kHz cavitation, a digital time and temperature panel and an SUS304 stainless tank and basket. The listing leans on small hardware, nozzles, carburetor parts and watch bands, and it encourages you to choose the temperature by material and stain type, with heating adjustable from 0 to 80°C. Side handles are included for moving the unit.
The honest limitation is documentation. The text we had does not give an ultrasonic wattage, a heater size or a timer range, and the phrase 15L-class suggests the working volume may be a touch under a full 15 L. That is worth checking against the product page. It also has no stated degas or gentle mode. In exchange you get a straightforward heated tank that fits repetitive parts cleaning.
In use it behaves like the others in the group: fill, set time and temperature, and run in short cycles. The side handles are useful, but a tank this size should still be emptied before you carry it. Compared with the VEVOR 15L Sonic Cleaner with degas and gentle modes it has fewer stated features, and against the 240W VEVOR it offers similar basics with less power information to go on.
Best for: Small hardware and metal parts where you want to set heat by material.
Check price on AmazonSpecs
- Frequency: 40 kHz
- Temperature: 0 to 80°C

Pros
- +Digital panel lets you set temperature by material up to 80°C
- +SUS304 stainless tank and basket keep items off the tank wall
- +Side handles make it easier to reposition the unit on a workbench
- +40 kHz cavitation suits nozzles, carburetor parts and small hardware
Cons
- −No ultrasonic wattage or heater size appears in the text we had
- −The 15L-class wording suggests a usable volume near, not at, 15 L
- −No degas or gentle mode is listed to protect more delicate items
VEVOR 15L Professional Ultrasonic Cleaner, 240W
About this pick
The 240W VEVOR is the lowest-power machine in this lineup, running 40 kHz with an adjustable 0 to 80°C temperature, a digital display, a stainless tank and a basket. The listing aims it at carburetor passages, airbrush tips, watch bands, hardware and lab components, and says an upgraded handle makes moving a full tank easier. Customizable time and temperature settings cover a range of soils.
The lower ultrasonic output is the main tradeoff, and it is a real one. Across 15 L, 240W spreads thinner than the 360W models, so heavy grease and larger loads clean more slowly and may need a second cycle. For some owners that is acceptable, because lighter parts and occasional use do not demand maximum power, and gentler output can be an advantage on thinner items. The listing does not mention degas or gentle modes.
Ownership is the same simple routine as the other VEVORs: fill, heat if needed, set the timer and run. If you mostly clean modest batches, you may never feel the power gap. Beside the CREWORKS at 360W and a 450W heater it is clearly the milder machine, and the VEVOR with the 400W heater and six transducers outputs 120W more.
Best for: Occasional users with lighter loads who do not need maximum ultrasonic output.
Check price on AmazonSpecs
- Ultrasonic power: 240W at 40 kHz

How We Evaluated These 15L Ultrasonic Cleaners
Each pick was assessed across 5 criteria weighted for real-world use.
Ultrasonic power and capacity
We compared the stated ultrasonic wattage against the 15 L tank volume. Four of the six machines list 360W, which leads the group, while the VEVOR 15L Professional lists 240W. We treated these as maker figures and weighed them against buyer feedback on cleaning speed.
Heating performance
We looked at whether a heater wattage is stated, how wide the temperature range is and whether the controls are digital. The CREWORKS at 450W and the six-transducer VEVOR at 400W lead on stated heater size. Where a wattage was not in the listing, we noted that rather than guessing a number.
Modes and material safety
We checked for degas and gentle modes, since they decide how well a big tank handles mixed loads. The CREWORKS and the VEVOR 15L Sonic Cleaner lead here, and the CREWORKS gentle mode halves power. We also noted the warnings around hot water for glued or plastic items.
Handling and build
A 15 L tank is heavy, so we weighed handle design, drainage and stainless construction. The VEVOR 15L Sonic Cleaner and the timer-and-heater VEVOR mention drainage, and the CREWORKS adds inset handles and a lid. All six use stainless steel tanks and baskets.
Clarity of specifications
We rewarded listings that publish dimensions, workpiece limits and power figures. The six-transducer VEVOR leads with a 13 x 11.8 x 5.9 in tank and a 10.6 x 8.7 x 4.1 in workpiece limit, while the 15L-class VEVOR gives the least detail. Gaps in the numbers were flagged, not filled in.
How to Choose the Right 15L Ultrasonic Cleaners
By Type of Load
Match the machine to what you plan to clean most often.
| Situation | Best pick | Why |
|---|---|---|
| Greasy hardware, tools and carburetor parts | VEVOR 15L Ultrasonic Cleaner, 360W with 400W Heater | Six 60W transducers and a 400W heater suit heavy soil. |
| Mixed loads with some delicate items | CREWORKS 15L Digital Ultrasonic Cleaner, 450W Heater | Gentle mode halves the 360W output for finer pieces. |
| Parts with tight bores and crevices | VEVOR 15L Sonic Cleaner with Degas and Gentle Mode | Degassing clears air so cavitation reaches inside. |
| Occasional light parts cleaning | VEVOR 15L Professional Ultrasonic Cleaner, 240W | 240W is enough for small batches and lighter soil. |
| Small hardware heated by material | VEVOR 15L-Class Ultrasonic Parts Cleaner, 40kHz | Digital panel sets 0 to 80°C by item and stain. |
Always rinse items after cleaning and keep delicate pieces in the basket, not on the tank floor.
By Budget
These tiers are relative, based on features and listed power rather than price.
| Tier | Pick | What you get |
|---|---|---|
| Entry | VEVOR 15L Professional Ultrasonic Cleaner, 240W | Lowest listed power at 240W with a basic digital timer and heater. |
| Entry to mid | VEVOR 15L-Class Ultrasonic Parts Cleaner, 40kHz | Heated, digital and handled, but with sparse power specs. |
| Mid | VEVOR 15L 360W Ultrasonic Cleaner with Timer and Heater | Full 360W output and drainage without extra modes. |
| Mid to premium | VEVOR 15L Ultrasonic Cleaner, 360W with 400W Heater | Published dimensions and a 400W heater. |
| Premium | CREWORKS 15L Digital Ultrasonic Cleaner, 450W Heater | Largest heater plus degas and gentle modes. |
Extra modes add flexibility, but if you only clean rugged parts a plain 360W machine does the same work.
Plain Power vs Degas and Gentle Modes
The extra modes change how the same 360W is applied.
Plain power
A plain unit sends full output through the tank for as long as the timer runs. That is ideal for rugged metal, tools and hardware, and it keeps controls simple. The VEVOR 15L with 400W heater, the VEVOR 15L 360W with timer and heater, the 15L-class VEVOR and the 240W VEVOR fall on this side. Pick it if you mostly clean parts and never need to soften the output.
Degas and gentle
Degassing removes dissolved air first so cavitation is stronger, and a gentle mode reduces the output for finer items. The CREWORKS 15L halves the ultrasonic power in gentle mode, and the VEVOR 15L Sonic Cleaner lists dual power settings. Pick these if your loads are mixed, and skip them if you prefer the simplest possible panel.
Choose plain power for parts only, and degas plus gentle if jewelry or boards share the tank.
Heater Strength and Warm-Up
A bigger heater shortens the wait for a cold 15 L tank to warm.
| Situation | Best pick | Why |
|---|---|---|
| You want the fastest warm-up | CREWORKS 15L Digital Ultrasonic Cleaner, 450W Heater | 450W is the largest stated heater here. |
| You want a stated, solid heater | VEVOR 15L Ultrasonic Cleaner, 360W with 400W Heater | 400W is listed, with a 0 to 80°C range. |
| You need heat but not a stated wattage | VEVOR 15L 360W Ultrasonic Cleaner with Timer and Heater | Heated cleaning is a headline feature. |
| You rarely heat the tank | VEVOR 15L Professional Ultrasonic Cleaner, 240W | Cold or lightly warmed cleaning suits lighter soil. |
Heat helps with grease but never use it on plastics, glued parts or soft stones.
For Garage and Hobby Parts Specifically
Carburetors, nozzles and small hardware need power, heat and sensible sizing.
Look for
At least 300W of ultrasonic power, a heater of 400W or more, a stainless basket and a tank depth that fits your parts. Degas helps with blind holes and passages. Always loosen heavy sludge first and use a suitable solution rather than plain water for oils.
In this comparison
The VEVOR 15L Ultrasonic Cleaner with 400W Heater lists the 10.6 x 8.7 x 4.1 in workpiece limit, the CREWORKS adds a 450W heater, and the VEVOR 15L Sonic Cleaner adds degassing for bores. The 15L-class VEVOR names carburetor components and nozzles directly.
Measure your biggest part first, since the six-transducer VEVOR tank is only 5.9 inches deep.
When to Spend More
Extra features pay off only in certain situations.
| Spend more if | Save if |
|---|---|
| You clean mixed loads and want gentle mode, as on the CREWORKS 15L | You only clean rugged metal parts on a basic VEVOR 360W |
| You want a 450W heater to warm 15 L faster, as on the CREWORKS | You can wait for the 240W VEVOR to warm or run cold |
| You need published dimensions, as on the six-transducer VEVOR | You already know your parts fit a 15L-class tank |
| You want degassing for blind holes, as on the VEVOR 15L Sonic Cleaner | You clean open, simple shapes where air is not a problem |
If in doubt, choose a 360W model, because the power gap over 240W shows up on every heavy load.
Frequently Asked Questions
Which 15L ultrasonic cleaner is best for most people?
For most buyers the CREWORKS 15L is the safest choice, thanks to 360W of ultrasonic power, a 450W heater and both degas and gentle modes. If you only clean rugged hardware, the VEVOR 15L with 400W heater and six transducers is a fine alternative with clearly published dimensions. The 240W VEVOR suits only lighter, occasional use.
Do I need a 15 L machine, or is a smaller one enough?
Fifteen litres makes sense when you clean long items, trays of hardware or several batches' worth of parts at once. For rings, glasses or a retainer, a 600 ml or 3 L machine is easier to store and lift. A full 15 L tank holds around 15 kg of water, so be honest about whether you have the bench and the strength to handle it.
Is the heater safe for everything?
No. Heaters on these machines reach 80°C or 176°F, which suits greasy metal but not glued parts, plastics, soft stones or oral appliances. Pearls, opals, turquoise, emeralds, amber and coral can crack or cloud, and treated stones may be affected. When unsure, run cold and use a short cycle.
Will an ultrasonic cleaner remove tarnish or rust?
Not by itself. Tarnish is a chemical change on the surface, not dirt, so ultrasonic cleaning lifts residue around it but leaves the discoloration. Rust and heavy scale need a suitable cleaning solution suited to the metal. Use the tank for the dirt and a polish or solution for the chemistry.
How long should I run a cycle?
Short cycles of a few minutes are normal, and the listed maximum on the CREWORKS and the six-transducer VEVOR is 30 minutes. Long continuous runs build heat and put extra wear on the machine. Run a few minutes, check the item, and restart the timer if needed, and never run the tank empty.
Do I need a cleaning solution, or is water enough?
Water alone works for light dirt, but oils, grease and heavier grime clean better with a mild solution suited to the material. Heat helps the solution work, which is why the CREWORKS 450W heater and the VEVOR 400W heater matter on greasy parts. Keep items in the basket and rinse them afterward.
How do I move and empty a full tank safely?
Switch the unit off, unplug it and let the heated water cool before you move anything. Use the drainage feature if your model has one, as on the VEVOR 15L Sonic Cleaner and the timer-and-heater VEVOR, or dip out most of the liquid. Then lift using the handles on the CREWORKS or the side handles on the 15L-class VEVOR.
