The Hi-Tech Gadget for Your Delicate Fashion

The Hi-Tech Gadget for Your Delicate Fashion

If you want to clean any item thoroughly- whether it’s your home or car- you’ll have to try different cleaning techniques such as scrubbing, spraying and rubbing - sometimes quite aggressively.

But when it comes to cleaning delicate clothes, using aggressive approaches can do more harm than good. Enter: Dolfi. This hand-sized device utilizes ultrasonic technology to remove dirt while being gentle on your clothes.

Ultrasonic cleaning is not a new concept. It’s already being used in industrial cleaning, the medical industry to clean dental equipment and in the art world by tattoo artists. In our post, we’ll focus on the Dolfi Ultrasonic Cleaner, how it works and what makes it so suitable for cleaning delicate items.

What is Dolfi Ultrasonic Device?

 This cleaning gadget is founded on a very simple premise: it gives you a portable way of cleaning your laundry. Amazing, right? However, don’t expect to use it to clean massive loads of clothes; just a couple of items at a time. The good thing is, you can leave it amongst your clothes, walk away, run an errand and come back after an hour to find a clean set of clothes!

Dolfi is aptly shaped like a bar of soap. Only, it works way more effectively than one. So all you need to do is fill your basin with water and some detergent. Next,  place the Dolfi cleaner at the bottom of the basin, then add your clothes.



Be sure to use warm water that is about 30°C. Also, it’s good to leave at least 5 cm of space between the gadget and your laundry. This will facilitate the ultrasonic cleaning process, which we’ll explain in a bit.

When putting Dolfi device to your basin, ensure the side with the logo is facing up. Finally, plug the gadget’s cable to a power supply and wait as the magic happens.

A distinct feature of the Dolfi ultrasonic cleaner that makes it superior to washing machines is the fact that it doesn’t require too much water. Even low-water washing machines need a significant amount of water compared to this cleaning equipment.

Now, we’re not saying that you should give your washing machine to charity and rely exclusively on the Dolfi ultrasonic cleaner. This ultrasonic device is meant to clean a handful of clothes at a time. This means it can only serve as a complementary cleaning device. While this cleaning equipment may not replace a washing machine, it’s suitable for those times when you have smaller wash loads. It will save you significant amounts of water as well as energy.

That said, it’s hand-sized structure makes it perfect for travel purposes. Plus, it’s more effective and convenient than hand-washing your delicate clothing.

How does Ultrasonic Cleaning Technology Work?

This is a process that uses high-frequency and high-intensity sound waves to agitate a fluid, which leads to the creation of bubbles or cavities.

But how does any of these processes clean your clothing?

Well, when these microscopic bubbles are forced into contact with a surface, they disintegrate or collapse. Once this happens, the surrounding liquid occupies the area where the bubbles were, creating a gentle scrubbing action that cleans the item. The gentle scrubbing is what is referred to as cavitation.

 Cavitation process

In recent years, there has been a demand for a higher level of cleanliness. This has spurred the development of more sophisticated cleaning technology. As we speak, it’s possible to tailor ultrasonic waves so as to utilize this technology in a vast range of applications.

Ultrasonic cleaning is not only used to clean clothing items but also medical tools, lenses, jewelry, firearms, golf clubs, car fuel injectors, musical instruments just to mention a few.

This method uses a highly-effective and unconventional way of eliminating foreign contaminants from the item being cleaned. The kind of results you get from this process are difficult to achieve using other technologies.

Competing techniques include spray washing, agitation, brushing, turbulation and more. One disadvantage with most, if not all of these methods is that they use an ‘out-of-sight’ mechanism.


Why Invest in Dolfi Ultrasonic Cleaner?

It’s lightweight and portable

 Even though it cannot be used to clean huge loads of clothes, there’s one thing that makes it stand out- its lightweight design. Dolfi ultrasonic cleaner weighs less than an ounce.

Award-winning design: given its weight and size, this cleanser is small enough to fit in your bag and carry it with you wherever you go. In terms of size, it measures 9 x 7.2 x 3 cm.

Save water and energy


One of the largest applications of water by American households is laundry work. The U.S. Environmental Protection Agency (EPA) estimates that a standard washing machine consumes up to 41 gallons (155 liters) of water per load. While there are a few washing machines that use smaller amounts, none can compare to the water efficiency of an ultrasonic cleaner like Dolfi.  

So, you can save water by choosing to use this device instead of a washing machine. With Dolfi, you need between 5 and 10 liters to clean your laundry.  

Another area where Dolfi has proven to be superior is in energy efficiency - it uses about 80 times less energy than a traditional washing machine.

Clean on the go


Are you planning a trip overseas and want a convenient way to keep your laundry clean? The Dolfi Ultrasonic Cleaner is the perfect solution. While a washing machine may be more effective in some aspects, its bulky design means you cannot carry it as conveniently as this tool.

With ultrasonic cleaning, all you need is a basin or sink, a detergent and the device. Within an hour, your clothes will be as clean as new.

For travelers, the ease of using this device really comes in handy. It means you don’t have to carry as many clothes since you already have an easy way of cleaning dirty laundry and reusing them.

Save time and money

Cleaning delicate clothing can be challenging. Pieces of clothing such as bike shorts, ties, and silk shirts can get damaged if you use a washing machine.

Traditionally, the alternative to a washing machine has been hand washing these delicates. But this technique has one glaring issue- it requires too much time and effort.

It’s also more difficult to remove stubborn stains when hand washing clothes. This is where the Dolfi Ultrasonic cleaner comes in. As explained earlier, all you need to do is toss the device in the basin containing your dirty laundry and water. Connect it to an outlet and leave it to do its work. You don’t even have to be present to monitor the process.

This also eliminates the need to enlist laundry and dry cleaning services; hence, saving you money and time.


How Can You Get The Most Out of An Ultrasonic Cleaner?

If you’ve used any ultrasonic cleaner before, then you’re familiar with the level of efficiency it provides when it comes to cleaning. That said, there are a couple of things you can do to ensure you’re making the most of this tool. These include:

Get the Temperature  Right

Different ultrasonic cleaners come with different guidelines on how to use them. In the case of Dolfi, the ideal temperature is about 30°C, which is also the right temperature for most of delicate fabrics.

Do not Operate the Device Out of Water

The device must operate in the water. It is equipped with a protection mechanism for the cases of draining washing solution, however you should never try to run it “dry”intentionally. If you’ve finished cleaning before the end of full 60 min cycle (when it switches off automatically), you need to make sure that you first unplug the device from the power outlet and only after that you can take the device out of the water.


Designed in a compact shape, Dolfi employs ultrasonic technology to clean your garments. Since it can only be used to wash small loads of clothes, it’s best used to compliment your washing machine. Another benefit of its lightweight design is that it’s portable, which makes it suitable for cleaning items on the go.

Its ease of use and efficiency are other aspects that make Dolfi investing in. While a standard washing machine requires a considerable amount of water, the pocket-sized ultrasonic cleaner only needs about 5-10 liters per load. Even better, it utilizes 80 times less energy than a washing machine.

If you’re planning to travel or looking for a more efficient way to clean a few clothing items, Dolfi Ultrasonic Cleaner is the perfect solution.

How to Wash your Lingerie and Delicate Clothing in 21st Century?

How to Wash your Lingerie and Delicate Clothing in 21st Century?

Underwear and lingerie make us feel confident, they might be underneath another layer of clothes but we choose certain items for certain moments when we need that inner confidence. 

So as we rely on those delicate items they need to be like the day we got them.  Perfectly fitting and structurally sound.

How many times have you second guessed throwing your lingerie and other delicates in the washing machine, pressing the Power On button and hoping they come out unscathed?  And do you remember how you felt when the inevitable happened and you realized what you had done?


I know it has happened to you too.  It's happened to us all, and it sucks.  Your confidence producing armor is damaged and you have that event tomorrow.


Lady frustrated after the washing machine ruined her delicate clothes


Why are delicates so hard to wash?

Delicate items are not called delicates by chance.  They are thin, fragile fabrics woven and constructed to do a job and we rely on them to do that job every time we call on them.  That fine construction can be damaged by spin cycles or by simply rubbing them together during handwashing. 

I know what you're thinking.  You handwash them to protect them from the washing machine.  But guess what, you pulling and stretching at the fibers that will deconstruct the original shape and compromise the overall shape and design.

We've moved away from rubbing our delicates against washboards but are we doing enough to preserve the integrity of our favorite delicate items?

The good news is, there is an answer.  And it's technology lending us a hand.  Ultrasonic technology that is.  Dolfi uses ultrasonic technology which radiates through water to clean your delicate pieces of clothing with no handwashing required. 

The science behind it is fascinating and I'll go into that shortly.  The important thing is with ultrasonic cleaning, there's no way to pull or stretch your fragile pieces of clothing out of shape so they always look and feel new.  And giving you that confidence time and time again.

How Does Dolfi Work? [Here’s the techy part…]

Put simply, the Dolfi device is packed with ultrasonic technology that can be applied to cleaning delicate fabrics without compromising the structure.

There is no mechanical rubbing or whirling during ultrasonic cleaning, the cleaning happens thanks to the cavitation phenomena. 

The device has a transducer inside that converts electric power into a range of soundwaves.  These soundwaves in water create millions of tiny bubbles. 

These bubbles then implode, creating jets of water (mixed with detergent) that dislodges the dirt from deep inside the fabrics.  This activity eliminates the need for washing machines or even hand washing. 

Industrial ultrasonic washing machines have been using this technology for years to clean mechanical components that would get damaged in other processes but now this technology is available for you at home so you can take care of your delicate items and cleaning them deeper than ever before.


How Ultrasonic Technology Cleans Fabric


Who benefits from Dolfi?

If you have delicate lingerie, a silk or lace blouse, a structured baby doll or any intricate piece of clothing that you don't trust the washing machine with, then try using Dolfi and see the results. 

Once you start washing with Dolfi you protect those items from damage, reduce the amount of times you have to buy new items and another wonderful aspect, you get your time back. 

When you use Dolfi you don't have to be there to do anything.  Just put it to work and come back later to hang it out to dry.  Sounds pretty sweet, right?


Why Dolfi is a game changer

Using Dolfi on your delicates will not only clean your items safely and deeply, it gives you back time you could be doing other things.  Plus it saves you money. 

And no, I don't mean money from not needing to buy new items but actual savings from not using the washing machine or dry cleaning.  Water consumption and electricity consumption is a fraction when using Dolfi over the conventional washing machine.

Dolfi doesn't completely replace your big load size automatic washing machine, although that would be awesome, that spot in my kitchen for me would become a pizza oven.  But anyway, it doesn't replace your washing machine, and it's not trying to. 

Dolfi is there when you're standing in front of the washing machine with your delicates in hand and you think to yourself "Am I going to regret this?"  that's when you reach for Dolfi and let it take care of business.

How This Portable Washing Machine Is Perfect While Traveling

How This Portable Washing Machine Is Perfect While Traveling

If anyone told me that in the near future we're going to have a portable washing machine in the size of a mobile phone, I'd have never believed him!

Modern technology has changed the way we live in infinite ways. Whether it's our life, work, or leisure time, there's always a machine or a device that has made our chores a much easier challenge for us.

Today, we're going to discuss one of the latest technologies that's going to take the world by storm; introducing the amazing Dolfi, the world's smallest and most gentle portable washing machine.

Let's take a deeper look at why this next-gen portable washing device can be the key to solving your laundry problems.

Why a Portable Washing Machine Might Be the Greatest Solution to Your Laundry Problems

If you’re a traveler who enjoys all kinds of outdoor activities, or you’re someone who always holds a plane ticket in his hands, whether it be for work or personal fulfillment, you’ll know the drill.

The worst laundry nightmare is when there's a lot of dirty clothes, and no washing machine or laundry services in sight. This leads us all to the inevitable. We open our bags, take out our smelly dirty laundry, head to the sink and get to work on handwashing them.

That isn’t the only problem. Going to the gym means sweaty clothes after a fruitful workout which inevitably means that we’ll need to do another workout afterwards to wash our clothes or inevitably destroy all those technologically advanced fabrics in the washer or dryer drum.

Even when you have your washing machine ready, there are sometimes these extremely delicate garments that you just can't throw in the washing machine for a quick wash.


Girl Frustrated with Washing Machine


All these were episodic samples of how dirty laundry and washing machines can be inconvenient and unreliable. Luckily, the new invention of the Dolfi portable washing machine is the perfect solution to these problems.

How Ultrasonic Cleaning Works

While a portable washing machine like Dolfi isn’t something that many people thought of before, the use of ultrasonic technology in cleaning delicate medical tools such as surgical and dental instruments has been around for quite a while now.

It's also the ideal way used by automotive companies to remove grease and oil from motors and all the other vehicle parts. Since it has proven its efficiency and efficacy throughout the years, it was only a matter of time before it’d be implemented on laundry as well.

Ultrasonic cleaning utilizes the ultrasound waves in frequencies that range above 20 kHz  inside water. These produced sound waves can’t be heard. However, they’re able to agitate the water due to rapid changes in the pressure inside the water.

When the pressure is drastically altered underwater by the effect of ultrasound waves, it produces a bubble cavity inside the water that’s filled with water vapor. This process is known as cavitation.

When the high pressure in the water vapor filled bubble meets the lower pressure of the water molecules, these void bubbles implode from the inside out and collapse, producing a powerful shock wave that creates millions of microscopic jet streams.

In the case of ultrasonic cleaners, these invisible microscopic jet streams produce agitative and strong pushing shocks that can safely wash the dirt and particles off the fabrics.

 Deep Cleaning with ultrasonic power


What Dolfi did was incorporating a small but highly powerful transducer inside the portable washing device. This transducer creates and emits ultrasonic waves of multiple frequencies that are multi-mode, wide-band, and progressive.

How Dolfi Portable Washing Machine Can Make Your Life Even Better

Dolfi offers some amazing benefits that make the next-gen cleaning device an ideal addition to your gadgets range.

Washes Different Types of Fabrics

Dolfi portable washing device is a perfect solution to a wide variety of fabrics. If you have some delicate material garments that are meant to be hand-washed only, then you’re in for a treat!

Fabrics like moire, cashmere, mohair, silk, lace and others aren’t washing machine friendly and they require a huge deal of caution while being cleaned. However, all these fabrics can be left for Dolfi without worrying about damaging them.

Not only is it perfect for lingerie and undergarments, but this portable washing device is also ideal for all kinds of light sportswear such as sports bras, leggings, workout outfits, sport apparel made of technologically advanced textiles, swimwear and swimsuits.

It is a great solution to wash at home shaped apparel such as light dresses, ties, hats, caps and bespoke decorated clothes such as embellished fashion or a jeweled shirt.




Dolfi is an extremely eco-friendly device that’s claimed to use about 80 times less power than a regular washing machine. It also operates on a very small amount of water - less than 10% compared to consumption of conventional washing machines that need to be continuously fed with water.


Having a portable washing device saves you lots of laundry service money. Additionally, you can say goodbye to all the tedious and time-wasting handwashing chores. And probably the biggest savings are your (often pretty expensive) favorite fashion items that will stay intact and in their best condition for much much longer if you let Dolfi to take care of them. Since Dolfi works without the need to rub, twirl, or stretch the clothes, there’s no risk of damaging them. 

Perfect Travelling Companion

Traveling with Dolfi is one of its greatest perks. The portable device is small enough to fit within your luggage without a hassle. It’s also packed with universal power plugs to allow using it almost anywhere you go.




Easy to use

One of the greatest things about Dolfi is that you don’t have to be a rocket scientist to use it. As long as you condition your water container right, all you have to do is plugging it to the wall and you’re good to go.

Works silently

If you’re tired of washing machine noises for washing even the lightest garments, then you’ll be pleased to know that Dolfi is extremely silent. That’s because our ears can't pick up or hear sound waves in ultrasonic frequencies.

The easiest way to tell that Dolfi is running by looking at its blue light  indicators when it’s powered on.


In addition to its cleaning properties, you can also use Dolfi portable device to wash and clean kids and babies small stuffed animals for extra freshness.

Although it isn’t claimed by Dolfi’s producers, according to many studies, high power ultrasonic waves also have a potent decontamination effect on fruits and vegetables.

How to Use Dolfi Portable Washing Machine Properly

Here are some tips that can help you through the process of using the portable washing device correctly.

The Type of the Container

When choosing a water basin for the washing cycle, you should look for a waterproof and hard container to serve as a water basin. Solid materials such as metal and ceramic basins are perfect for Dolfi.

The Right Amount of Water

Water creates the required medium for Dolfi’s ultrasonic waves to work. Consequently, the more water in the sink, the better the results are going to be.

Having a low amount of water in the sink means a smaller field of active ultrasound waves. This also diminishes the cleaning effect..

A golden rule of thumb while using Dolfi is to have 5 to 10 liters of water for every one or two pounds of laundry. You’ll know that you’ve added enough amount of water when the fabrics start to float freely on the surface. Be sure to leave some space between the Dolfi device and the fabric, optimal positioning would be the fabrics free-floating about 5 cm above the device.

The Ideal Water Temperature

The water’s temperature should be hot enough to maximize the effect of cleaning, but not too hot to burn your hands, as such temperature can also ruin your delicates. A warm 30 to 40 °C (85 to 105 °F) bath can do the trick.

Keep Dolfi Underwater While Running

To avoid overheating and malfunctioning, you should always avoid turning the washing device on while outside of the water or have it in an unplugged sink.

Placing the Device Correctly

Make sure to put the Dolfi device at the bottom of the sink or container with logo facing up.

If you’re going to use it on one piece of fabric with a tough stain, the fabric should be placed directly over the device with a gap of about 5cm between them. This is where the ultrasonic field is the strongest.




Pre-treatment and Detergents

Even the most powerful regular washing machine requires pre-treatment for some of the tough stains. Similarly, Dolfi portable washing device needs some external help from detergent and stain removers to remove difficult stains.

While Dolfi can work perfectly on stains like wine, blood, juices, and coffee, some thicker stains like mustard, cream, ketchup will require some detergent enhancers to remove them.

The Minds Behind Dolfi Portable Washing Machine


Dolfi is a startup company that was founded by Lena Solis, an innovative entrepreneur who came up with the idea of using the powerful technologies of ultrasonic waves for washing clothes.

The word “Dolfi” is derived from “Dolphins” to pay tribute to the most advanced users of the ultrasound on earth. Dolphins masterfully use ultrasound waves for communication, echolocation, hunting, and orientation under the water.

The idea of a portable washing machine came up to Lena Solis when she was frustrated by some local laundries experiences and hating to hand wash her clothes she was looking for a solution.

After examining the field of ultrasound technology and exploring its versatility and wide range of applications, she enrolled the best minds in the business, the Centre for Ultrasonic Engineering (CUE) and product designer Andre Fangueiro.

They then worked together to produce a miniature device that can utilize the power of ultrasound technology and solving a problem that hundreds of thousands of people face daily.

Wrapping It Up

Although Dolfi portable washing device is highly versatile and functional, it can’t replace a regular washing machine nor it can wash and clean many kilos of extremely dirty clothes.

If you’re seeking the best result out of a Dolfi washing device, then you should never use it with heavy-duty greases like engine oil, large volume items such as bedsheets and towels, or heavy fabrics such as jeans and blankets.

However, Dolfi can be a perfect complimentary device to your washing machine, as it can help protect the delicate and fragile items such as chiffon, silk, lace sheer fabrics and other fabrics that a regular washing machine might destroy.
