What exactly is a water flosser?

An oral irrigator/water flosser is an electric oral hygiene device with a water tank and a nozzle that releases a stream of water with adjustable pressure.

It works like a small high-pressure cleaner for your teeth: the focused water stream rinses away food particles and plaque from between the teeth and along the gumline — areas a toothbrush cannot easily reach.

The cleaning is done gently with water pressure instead of mechanical pressure, helping to provide a deeper clean and a fresh feeling in the mouth.

Is the application gentle on the gums?

The application is specifically designed to be gentle. HydroPulse™ technology cleans with variable water pulses instead of mechanical pressure – removing plaque and food particles without irritating the gums. Users with sensitive gums can start with the gentlest setting (Soft) and increase the intensity if needed.

Who is an oral irrigator suitable for?

In general, it is suitable for anyone who wants to take their oral hygiene to the next level.

The Sonic Mini is especially useful for people with tight spaces between their teeth, sensitive gums, or a higher need for thorough cleaning. It can also make daily care easier for those with braces, aligners with attachments, implants, crowns, or bridges, as it helps clean hard-to-reach areas more effectively.

It is also a great choice for anyone who values gentle yet thorough oral care.

Compact design

At just 12 cm in height when collapsed, the Sonic Mini is significantly more compact than conventional water flossers. It fits securely in the hand and easily fits into a toiletry bag or luggage when traveling – without compromising on cleaning performance.

Gentle cleaning

The HydroPulse™ technology of the Sonic Mini thoroughly cleans between the teeth with variable water pulses that are gentle even on sensitive gums. A noticeably clean feeling without making the application uncomfortable.

Easy refilling

The 140 ml water tank is quick to refill and can be conveniently topped up at any time using the integrated refill flap. The nozzle is hygienically stored within the same compartment – thoughtfully designed for everyday use and travel.

Built to last

A full charge of the Sonic Mini lasts for up to 50 days of daily use. This makes it a reliable companion even on longer trips – and it can be fully recharged in just 4 hours.

Dani K.

For me, a water flosser has always been an essential part of oral care. However, since I never really liked the bulky designs of other brands, I decided to go with the Sonic Mini. The performance is truly impressive, and I especially love the foldable design.

Claudia H.

The packaging and overall look are really impressive, I have to say. The cleaning performance is also spot on, especially the gentle cleaning mode, which feels very comfortable, and it removes food particles thoroughly as well.

Jan D.

It feels very high-quality, fits comfortably in the hand, and has plenty of power. There are actually four attachments included, not three, and it also comes with a tongue scraper nozzle. My favorite, however, is the Clean Plus attachment.

Julia S.

It felt a bit unusual at first, but by now it has become part of my daily routine. The device works really well.

Got any questions?

What exactly is a water flosser?

A water flosser is an electric oral care device with a water tank and a nozzle that releases a stream of water with adjustable pressure. It works like a small pressure washer for your teeth: the concentrated water jet removes food particles and plaque from between the teeth and along the gumline – areas a toothbrush cannot properly reach.

The cleaning is done gently through water pressure instead of mechanical force, providing a more thorough clean and a fresh mouthfeel.

How does the 30-day money-back guarantee work?

It’s not always easy to judge a product online. That’s why your purchase comes with a 30-day money-back guarantee, allowing you to try the Sonic Mini at your own pace. If it doesn’t meet your expectations, you can simply return it to us and receive a full refund of the purchase price. Please note that return shipping costs are not covered by us.

How exactly does the application work?

Using the Sonic Mini is simple and convenient: Thanks to its compact telescopic design, it can easily be extended for use. It can then be filled with water either through the integrated refill flap or via the fully removable water tank. Afterwards, simply position the nozzle between the teeth and start the device with the push of a button. The water stream effectively removes food particles and thoroughly yet gently cleans between the teeth. The nozzles can also be changed easily thanks to the convenient click system.

Do I even need dental floss anymore?

Dental floss can still be useful for removing buildup between the teeth. However, in many cases, thorough daily oral care with a toothbrush and a water flosser is sufficient, allowing dental floss to be used as needed.

Does the Sonic Mini make my teeth whiter?

The Sonic Mini uses a targeted water stream to flush out food particles and bacteria from between the teeth and along the gumline – areas that a toothbrush often cannot reach properly. Thanks to the deeper cleaning, surface stains caused by coffee, tea, or similar substances can be reduced, making your teeth appear naturally brighter. While it is not a replacement for professional teeth whitening, a visibly improved overall appearance of your teeth is absolutely realistic with regular use.

Is it safe to use on the gums?

Yes, using the Sonic Mini is generally safe for the gums. Cleaning is done gently with water, and the intensity can be adjusted, making it suitable even for sensitive gums. For beginners, it is recommended to start with the lowest pressure setting. The sensation may feel unfamiliar at first, but after a few days it typically becomes part of a regular routine.

Is a water flosser suitable for children?

Yes, a water flosser can also be suitable for children – especially if they wear braces or have difficulty cleaning between their teeth thoroughly. It is important that it is used age-appropriately, with gentle water pressure and ideally under supervision.

When does a water flosser make sense for me?

A water flosser can be a good choice for you if food particles frequently get stuck between your teeth or if you want to clean hard-to-reach areas more effectively. It is especially helpful for tight interdental spaces, braces, bridges, or aligners, making daily oral care easier and more comfortable.

How long does the cleaning take?

Cleaning with the Sonic Mini takes around 30 seconds. At first, it may take a little practice to get used to the new routine. On the lowest setting, the integrated water tank provides up to 45 seconds of cleaning time.

How do I clean the Sonic Mini?

To keep the Sonic Mini clean, the water tank can be fully removed and easily rinsed with a little dish soap if needed. The housing is waterproof and can be cleaned effortlessly with lukewarm water.
