We know flossing is an important part of dental hygiene, but how many of us floss regularly and make it a routine? It is clear that besides brushing teeth, flossing is another oral care practice we should do. Water flossers are effective, convenient, and a quick way to floss your teeth. You shouldn’t skip flossing by any means. A cordless water flosser is yet another oral care product that we like to keep our dental health improved, just like the electric toothbrush.

What we recommend

Best overall: Waterpik Cordless Advanced Water FlosserWP-560

Best for travel: Panasonic EW-DJ10

Best design: Burst Water Flosser

Best budget: H2ofloss Cordless Water Flosser (HF-2)

Best battery-operated: Waterpik Cordless Express       

Traditionally, you can grab a thread floss and remove the food leftovers from between your teeth, which is good and recommended daily. But for some, it may be tedious or even painful since they can’t get the techniques right. Therefore, you can consider a cordless water flosser to complement your flossing habit.

Best Cordless Water Flosser is especially of great benefit when manual dexterity is an issue or when you have a crown, implant, or wearing an orthodontic appliance like braces. Along with your toothbrushing with fluoride toothpaste, using a water flosser can help more plaque removal. Also, it improves your gum health with the risks of gum diseases reduced.

What is a cordless water flosser?

Water flossers, or oral irrigators, help clean the teeth by spraying a steady stream of water. After filling the reservoir with water, put the tip (nozzle) on interdental spaces between your teeth and above on the gum line. Then turn on the device and it does the cleaning.

A cordless water flosser is a rechargeable and handheld device that is portable and compact. You don’t need a power outlet right next to your sink and it takes much less space which makes it suitable when you are on the go and traveling.

Countertop water flossers are larger-sized types that need to be plugged in while you want to work with them.

What to look for in a cordless water flosser?

There are several factors to keep in mind before buying your cordless water flosser. You can ensure that you get the most out of your purchase when you consider features like:

Power source and battery life.

Some cordless water flossers have a built-in rechargeable battery while other models are powered by replaceable batteries. Try to notice that and also the battery life of each.


If you are looking for an oral irrigator that takes much water and has a larger water reservoir, opt for one that suits you. Having a larger water tank can mean a longer time peruse and will decrease the number of times you refill the appliance to clean all the hard-to-reach areas of your teeth. 

Pressure mode/adjustments.

You can customize the flossing experience even more with different pressure settings or the rhythm of water pulses or bursts. You might like cleaner teeth and the ability to remove tough, sticky food debris by adjusting the flosser to higher pressure modes. Or, you can change to lower pressure mode in case of sensitive teeth or sensitive gums. Depending on the models, there may be about 2 or even 5 different modes, like the gum massaging feature, which can be soothing.


There are water flossers like Waterpik and Philips brands that have the American Dental Association (ADA) Seal of Acceptance. You can then be ensured about the safety and effectiveness of these models. But there are others that may lack ADA label yet have high-quality customer service.

360-degree rotating nozzle.

Water flossers have transformed our interdental cleaning. There are even greater benefits in 360-degree rotation tips that give flossing techniques to be far from any difficulties.

Gripping design.

The cordless models should offer appropriate handle designs with better quality materials. By that, you can grip the device comfortably in your hand during work and prevent slippage when it gets wet.


Always consider that the product you buy is under warranty, typically 2 or 3 years. The water flosser might be defective or fail as it can happen especially for an electrical device. Regarding the above features, we chose the list of best cordless water flossers on the market also by taking into account more issues like:

  • Online customer reviews. We checked the different online retailers like Amazon and official websites to get down to the most relatable and trustable reviews. 
  •  Key features. We explored the most noticeable factors that make each model popular or stand out among the rival models.
  • The price. There may be relatively expensive brands but there are choices of more affordable cordless water flossers to fit your financial needs.

Water flosser vs string floss

Both string floss and water flosser make good combinations for the elimination of plaque. But this is all achieved when you brush your teeth daily too.

Water flosser uses the jet of water through different modes to remove plaque and food residue from between your teeth. It is a novel way of cleaning teeth and gums, and it provides a couple of advantages over string floss.

With the jet tips and 360-degree rotatable nozzle, you will have the benefits of cleaning all the hard-to-reach parts of your teeth, like molar teeth, upper and lower interdental gaps, and gum line. Both water flosser and string floss have their own advantages.

Advantages of water flosser

  • Efficient plaque removal. It has the potential to disrupt more plaque buildups between your teeth and clean the gum line where string floss cannot reach.
  • Water flossers are quicker and much more convenient to use.
  • Give a pain-free flossing experience and there are no more gum pains and irritations.
  • Enhances gum health along with your dental health.
  • Suitable for people who have braces, aligners, bridges, dentures, crowns, and implant restorations.
  • It is an alternative to string floss for individuals with limitations in using hands correctly or with manual dexterity issues.

Advantages of string floss

  • Traditional floss has been an effective plaque removal method as well especially when used daily and with the correct technique.
  • It allows for more techniques to use the thread in any movements manually to clean between the teeth.
  • It is cost-effective and far cheaper.

Tips to remember before using a water flosser

  • Try to use a water flosser daily and make it a routine.
  • Follow the correct techniques in how to get cleaner teeth and mouth.
  • Brush your teeth twice daily with fluoride toothpaste for two minutes.
  • Using a water flosser can be messy, so use it over a sink to flush out excess water frequently.
  • Before using your device, check whether you can use the mouthwash in the reservoir. Not all brands offer that.

How to use a water flosser

  • Start by filling the reservoir with water.
  • If waterproof, you can use it in the shower unless getting access to the sink.
  • For first-time use, try to test the pressure of the water jet to see how it works.
  • Put the nozzle (tip) in your mouth and make sure the tip is pointing to your gum line.
  • Turn on the device and choose the mode you want.
  • Move the tip between each tooth and the gum line slowly.
  • Keep your mouth closed enough to prevent splash but you should let the excess water flow out of your mouth.
  • Rinse your mouth to get rid of loosened food and plaque.
