What is a Cordless Water Flosser?

A cordless/portable oral irrigator utilizes water pressure to clean between the teeth and gums. It is much like a standard model, only it does not require a cord. It is rechargeable and portable. Portable oral irrigators are perfect for travel and bathrooms with a small amount of counter space.

In an evaluation comparing the performance of a water flosser vs. string floss to remove plaque, the water flosser was 29% more effective than string floss for overall plaque removal.

How does a Cordless Oral Irrigator Work?

A portable oral irrigator has several different water pressure settings, all clinically proven to be safe. It is recommended to begin at the lowest setting and work your way up over time. The pressure of the water is enough to break down and remove the plaque or food stuck in the teeth.

The water is held in a reservoir, which is then emitted through the handheld tip. Make sure the reservoir is filled with lukewarm water. Simply place the tip in your mouth after choosing a pressure setting. Slightly close lips to avoid splashing. Work your way around the teeth and let the flosser do the rest.

The cordless models typically include a charging unit for the battery-operated device. It is important not to let the battery completely drain.

Pros & Cons of a Portable Water Flosser



  • Compared to a standard model, the cordless version has a more compact, lightweight design and the hassle of a tangled cord is eliminated.
  • It takes up less space in the bathroom. It's portable design makes it a perfect choice for those who plan on travelling.
  • It's quicker and easier than traditional dental floss. It has been clinically proven to be more effective than regular floss at reducing gingivitis, bleeding of gums, and removal of plaque.
  • Great for people with implants, braces and orthodontic appliances. It can be very difficult for people with braces to use dental floss around the wires of their braces. The irrigator's orthodontic tip makes it easier to get to those hard-to-reach areas.
  • Portable irrigators draw power from a battery. The drawback to that is it needs to be charged in order to use it. It should be charged at least once per month if not in use.
  • Due to it's compact design, the water reservoir on a portable oral irrigator is not as large as that of a countertop model. It will need to be refilled more often.

Choosing a Cordless Oral Irrigator - Buying Guide

Here are some important factors to take into consideration when choosing a cordless oral irrigator:


  • Where do you plan on travelling with your oral irrigator? If your plan is to go abroad to travel, and you want to bring the water flosser along, it is important to find one that has a charger with universal voltage or bring back-up batteries if required.
  • Take a look at our chart here to see which of our top 5 cordless water flossers have universal/global voltage.
  • This means the device's charger can accept both 110-120V and 220-240V. If you do not have universal voltage, it will either not work properly… or it might burn out. However, if your plan is to travel within the country then global voltage is not necessary.
  • Some H2O flossers come with a bonus travel case for ease of packing.


  • It is important to make sure the oral irrigator your purchase has at least a one year warranty. You never know what could go wrong and one year gives the consumer enough usage time to make sure it doesn't have any problems right out of the factory.
  • The last thing you want to be stuck with is a dud that has no warranty.


  • Portable oral irrigators usually come with 1 or more different kinds of tips such as regular, orthodontic, tongue scraper etc.
  • If the consumer is looking for a specific tip, they will want to make sure it comes with it so that no extra purchases are needed.

Look at reviews:

  • The best way to make a good purchase is to see what other customers are saying about the models you are considering.
  • Take a look at the star rating.


  • Learn about the various features included in certain models besides tips and warranty. They include water pressure settings, massage mode and timers to name a few.
