View Product On Amazon

When a ToiletTree oral irrigator tool is a part of the scene, nothing can defeat its high-quality design. The durability of this best cordless water flosser is the greatest convincing aspect. But that doesn’t mean the other characteristics are any less. So let’s find out more!

The Poseidon Oral Irrigator offers dual charge system. The outcome is that you can charge the device at home and when traveling. And that means, as a portable unit, it lives up to your expectations.

The three different operating modes are pulse, soft, and normal. Soft is suitable for sensitivity issues and normal is a perfect mode for daily use. But it’s the pulse setting that steals all the limelight. And that’s because the mode is capable of eliminating the toughest plaque. As an added bonus, the operation is not so loud as compared to other models.

Furthermore, the cost-effective feature comes in the form of interchangeable tips. These make it possible for more than a single person to use the cordless water flosser.

And lastly, the batteries are light and small since they’re lithium ion. The little beasts deliver more power along with increased energy density. They have the capacity to run for as long as eight hours when charged. Plus, the batteries recharge pretty fast in a limited span of time. What more do you need, right!

​The compact ToiletTree oral irrigator doesn’t take up space more than 2-3 inches on the countertop. And you know what; the cordless appliance operates for at least two whole weeks on a single charge. Even if you use it twice daily!

My only complaint with the Poseidon is that its on/off power button does not have a recessed quality. So the device might turn on all by itself inside your bag or suitcase.

All three pressure modes are low-noise.
​High-grade design and construction.
The inductive charging feature adds more convenience.

Water pressure tends to be too hard in higher settings.
The on/off switch gets activated easily.

The thing contains vibrating bristles in a high-low pattern. These do an excellent job of breaking up plaque. Even in the hardest to reach spaces!

Now let’s talk about the Waterpik Cordless Professional WP-440 Water Flosser. The unit offers a remarkable combination of pulsations and water pressure. Such an action goes deep between your teeth and under the gum line. This means it reaches vulnerable areas. To end debris and bacteria that other methods fail at doing.

So it’s a shame that the manufacturer doesn’t succeed at providing a seamless user experience. The main problem lies with the battery of the device. Eventually, it tends to stop charging. And that can be quite a nuisance to deal with, right?

Furthermore, this best cordless water flosser has a waterproof body. This way, you can wash and clean it without any worries.

Unfortunately, due to the poor hold, the device is not comfortable to use. But with time, your hands get well accustomed to the shape and learn to grip better. Up until then, expect a messy flossing experience.

The rotation of the tip during irrigation is quite impressive.

Using it properly takes a while.

But there is a common issue with cordless units that offer more than 2-3 pressure settings. And here’s what it is.

Everything You Need To Know About Cordless Water Flosser


The cordless version came into existence as a result of humans craving more convenience. As consumers, we’re always looking for ways to make life easier. So if that’s the case, then it makes sense to buy the best cordless water flosser.

Maintaining oral hygiene when traveling is something you can achieve only if the device is portable. Using a corded version, on the other hand, might not be such a brilliant idea. The cord almost always gets tangled. And during travel, you don’t want to deal with that clutter!

So the whole purpose of the guide section is to push you in the right direction. Making an impulsive decision by purchasing a poor quality unit is what you should avoid.

With that in mind, let’s find out more about the product at hand.

What Are Cordless Water Flossers?

A portable/cordless oral irrigator device cleans the area between your gums and teeth. And it does so with the help of water pressure. The major difference between this and any standard version is the lack of a cord. And that means the cordless option is portable and rechargeable.

So it’s an excellent choice for bathrooms that offer limited counter space. The unit is also suitable for when you’re traveling, isn’t it?

And here’s a fun fact. When compared to string floss, any water flosser is more persuasive at removing plaque. So there’s the most appealing aspect of a cordless water flosser! (Benefits of flossing)

Cordless or Corded: What’s the deal?

The corded and cordless devices both serve the same purpose. There’s no doubt about that! They serve one purpose only. And that is to clean gums, heal sensitivities, and remove plaque.

But the cordless flossers provide an extra advantage. It comes in the form of portability. I would also like to add that the corded appliances rank as more powerful. That’s the only tradeoff here.

In return, you get a water flosser that is rechargeable, compact, and long-lasting. So it’s time to find out all about the features of the cordless unit.

What Are The Factors Involved In Choosing The Best Cordless Water Flosser?


Battery Life

The number of hours a cordless flosser runs before recharge says a lot about performance. A long battery life means more convenience during travel, right? So don’t forget to take the device’s battery life into consideration during the buying process.

Water Tank Capacity

Take any cordless model and you’ll find that its water tank capacity is lower. Corded flossers have a much larger water tank. But that doesn’t mean settling for something that doesn’t suit your requirements.

There are many brands that manufacture effective cordless water flossers. And these are the ones built with a tank capable of pumping out jet for as long as 45 seconds. So you should aim for such units!

Pressure Control

With the invaluable pressure control advantage, you get a device that bodes well with your tooth sensitivity. Initially, you begin with least pressure. And when you wish to get rid of stains and plaque, you can switch to high pressure. That’s the beauty of this particular feature.

Gum Sensitivity

Every best cordless water flosser offers an important function. And that is to comply with the natural sensitivity of your gum line. Such a factor is something that you should never forget to take into account.

The plaque located below your gum line requires as much attention as the operation of the flosser.

Travel Friendliness

Being corded and travel-friendly are two different things. You can’t have both at the same time, am I correct? And since you’re reading an article about cordless water flossers, I’m going to hold portability in high regard.

But even some cordless options on the current market are not that easy and convenient to carry. So at such times, look for an appliance that delivers more power and takes up less space.

Action Against Plaque, Bacteria, and Gingivitis
The flosser is no good if it doesn’t end plaque, bacteria, and gingivitis with the most ease. Only when the product provides relief in under two weeks is confirmation that it’s up to the task. Such an action reduces the growth of bacteria inside your mouth through long hours of sleep and rest.


My Choice: Oral Irrigator by Poseidon

Convenience is the only factor responsible for the success of cordless water flossers. So there’s no reason to believe that the New Poseidon Oral Irrigator does not provide such an experience. This best cordless water flosser is the only pick that performs exceptionally well. And that too in all significant aspects!

When it comes to removing plaque, this ToiletTree oral irrigator doesn’t let you down. It is a total space-saver and easy to assemble as well as operate. On top of that, the manufacturer has also included two extra heads/tips. This is great for many users!

So everything about the unit is well equipped to handle whatever you throw at it!
