Best Cordless Water Flosser 2020 1

The use of a water flosser can reduce the existence of bleeding of gums by up to 93%!

A water flosser is a more gentle, comfortable and convenient way than the traditional flossing that your dentist always goes on about.  In fact, water flossers reach areas of the mouth normal flossing can’t.

There is a problem though; many water flossers need mains power which means you are potentially restricted in term of where and when you use it.

Thankfully the cordless water flosser exists and after hours of research and testing, we can conclusively tell you which are the best and why.

Below is our list of recommendations, what we like about each flosser and why, plus a link to a more detailed review in case you want more information. 

Later on in this post, we also include a buyer’s guide with a full explanation of water flosser and their features.

The article is broken up into several sections:

Our Top 5 Picks For Best Cordless Water Flosser

In the sections below you can read a little more about each water flosser and the reason we have included it.

1. Sonicare AirFloss Ultra

Short review: Perhaps not strictly a water flosser, the AirFloss uses a combination of water and air to achieve a similar effect but delivers short sharp bursts to get in between the teeth.

What makes it so good and desirable is the much smaller profile, it’s cordless, really easy to use and can achieve a clean in 30 seconds. It makes for effortless everyday use.

The Ultra model offers 3 different burst configurations so you can select the mode that is right for you.

The unit comes in 3 different colour options.

Whilst the AirFloss is actually our preferred go to flosser, clinical studies show Waterpik models are better.

2. Waterpik WP-560 Cordless Advanced

Short review: The best true cordless water flosser.

A good size water tank, with variable pressure settings built into a smart and appealing unit.

The box contents is good. It is by far the cheapest, but it is made by a leading brand and is clinically proven.

With a built-in rechargeable battery complete with magnetic charger it is convenient to use, although the battery life could be better.

3. DentJet DJ-159 Cordless Water Flosser

Short review: The DJ-159 takes the challenge to the brand leaders by offering an equivalent product for at least half the price.

Perhaps unsurprisingly it does not look or feel quite as refined as the premium models. It feels a bit cheaper and I have resevations about the long term reliability.

However, this cordless unit is powerful with 3 different modes to suit most users.

The handle is IP rated and the 200ml water tank will allow for a quick interdental clean.

2 nozzles and a travel pouch are included.

What I like

  • Value for money
  • Cordless

  • 3 modes

What I dislike

  • Unknown brand
  • Quality and reliability

4. Waterpik WF-03 Cordless Freedom

Short review: Cordless and powered by AA batteries this is a little more versatile for those away from power or do not have a power socket in the bathroom.

From the brand leader the tank is a reasonable size with the option of using different tips.

2 pressure modes is appealing but the overall bulky size and the slightly cheap feel to it is disappointing.  Overall pretty good value when you compare to some of the other options.

5. HAUEA 5 Mode Cordless Flosser

Short review: In truth it is really hard to find fault with this product when you consider what you get for the money.

It certainly take the challenge to the larger brands.

What you lose out on in brand reputation and possible product quality you more than make up for with value and box contents.

The cordless unit has a built-in rechargeable battery that can last for 10-12 days.

The 6 included tips can be rotated as it pushes out water from the 240ml tank.

And as you use it you can select from one of the 5 modes come pressure settings, so you can find the one that suits you best.

Cordless Water Flosser Buyer’s Guide

Corded water flossers are better (for some)

Right, let’s not mess about here.

From a scientific, everyday-use and results perspective you are going to get the best experience from the larger, bulkier and mains hogging countertop water flossers.

They will normally offer more features such as variable pressure settings and larger water tanks that ultimately affect your user experience.

But, the cordless and wire free options are good enough for the vast majority of us and still bring significant benefit.

What is a cordless water flosser?

A cordless or portable water flosser is an oral hygiene product that is powered from built-in batteries.

When switched on, the batteries power the pump that draws water from the refillable tank/reservoir and pushes this out at pressure via a nozzle you align with your gumline.

The water dislodges food particles, bacteria and plaque both on and underneath the gums, that was not removed through regular brushing to leave you with a cleaner and healthier mouth.

Water flossers are a type of interdental cleaning, like regular flossing or interdental brushes, which should be used in addition to brushing (preferably with an electric toothbrush!).

No power cable means you can move around more freely and floss where and when you choose.  This is particularly helpful for those who travel frequently or do not have a power outlet in the bathroom.

Oh, and if you see the words oral irrigator, it’s the same as a water flosser it’s just another name for them.

Waterpik is also a name you will see, this is in fact a brand name that has become synonymous with water flossers.

Pros and cons of cordless water flossers

There are pros and cons to water flossers in a general sense as well as those that are specific to cordless flossers.

For example all water flossers, cordless or not, tend to be easier to use, softer on the gums, offer a better clean and reach more of the tooth surface in comparison to regular flossing.

A con is that the technique does take some getting used to and they are initially anyway, more expensive than normal string floss.

Listed below are what we consider the pros and cons of cordless oral irrigators specifically.

Benefits of a cordless water flosser

  • Size/portability
    • Much smaller than the countertop alternative they can be stored out of sight, taken away when travelling as they will more easily fit in a bag.
  • Internal batteries
    • Batteries inside the flosser, be those user replaceable or rechargeable mean you are not attached to a power outlet and you can go where you want with the flosser.

Negatives of a water flosser

  • Tank/reservoir size
    • To be portable, the flossers need to be smaller and the tank is the biggest compromise.  Often enough to just do the job, you have to frequently refill.
  • Batteries/recharging
    • The batteries are built-in and need recharging or are user replaceable AA design often.  They need frequent charging due to the power used and often the chargers connect to 2 pin sockets, which is one of the appeals for going cordless in the first place.

Do I need a portable flosser?

It depends.

None of us NEED one, but there are health benefits from owning a water flosser.

There is then the added benefits such as size and portability that the cordless option bring which in truth generally outweighs the cons by quite some considerable distance.

With over 47.2% of over 30’s in the USA alone suffering from gum disease according to the Centre for Disease Control and Prevention,  and the proven benefits of the water flosser there are very compelling arguments to own one.

Common signs of gum disease are red or swollen, tender or bleeding gums.  

Best Cordless Water Flosser 2020 10

This is normally caused by poor oral hygiene and regular flossing can help, but water flossing in particular is more effective and comfortable to do.

A 2005 study found that the addition of a water flosser to a daily oral healthcare routine resulted in a 93% reduction in bleeding and up to 52% better at reducing gingivitis (inflamed gums) than traditional dental floss.

Other studies have shown that water flossers are able to remove more bacteria, reduce more bleeding, plaque, and gingivitis in comparison to interdental brushes and to just toothbrushing alone.

Dr. David Jolkovsky, a diplomate of the American Board of Periodontology, wrote a literature review that unequivocally showed that a Waterpik Water Flosser reduces inflammation, removes bacteria from deep periodontal pockets, does not cause damage to mouth tissues and is in the same range as brushing teeth, flossing, and using wooden sticks in the incidence of bacteremia.

Recent guidelines also recommend that the use of a water flosser is even safe for those who require antibiotic cover for dental treatment.

Such high praise has made water flossers a must have healthcare gadget, but daily life means the countertop option is not always practical, particularly if you lack a power outlet in the bathroom or travel frequently.

As you will see from our recommendations at the start of the article, Waterpik and Sonicare are just two big brands within this space, but ultimately Waterpik are industry leaders.

What makes a good cordless water flosser?

So although compromise for some features has to be made to make a cordless flosser portable there are some key things to look out for.

You will see that our highest ranking recommendations will boast these features.

  • Water tank/reservoir size

Smaller than the countertop options it is about finding those with the largest tank but keep the unit portable.

  • Adjustable pressure settings

Adjustable pressure can help ensure you get a more comfortable user experience.

The best cordless options will offer at least two options here, typically high or low with a pressure measured in Bar, varying from 3.1-5.2.

Best Cordless Water Flosser 2020 12
  • Size/travel friendly

It is somewhat of a catch 22 in that you want the largest tank, but you want flosser to be small enough to be portable.

Frequent travellers take note of the size and ease of which it can be fit into a bag.

  • Different tips

The more premium models, particularly those from Waterpik offer a range of different styles of interchangeable tips.

Whilst the classic jet tip is most common across all brands, the more specific options work well for particular user requirements.

Those with braces will wish to make use of the orthodontic tip whilst those who have dental work such as dental implants, tooth crowns and bridges will find the plaque seeker tip most beneficial.

Best Cordless Water Flosser 2020 13
  • Adjustable/rotatable nozzle

Some allow you rotate the nozzle, they are not completely fixed giving greater flexibility in reaching certain areas of the mouth.

Some rotate a full 360 degrees thanks to a click wheel style adjustment.

So, here then is our list of best cordless water flossers with extra detail on why we have picked each one and what we like.

Travelling with a cordless flosser

Depending on the model you choose will depend on the exact power and connector that comes supplied with it.

Most power cables for recharging the water flosser come with a 2 pin connector, designed to be connected to the power socket found in a bathroom.

Best Cordless Water Flosser 2020 14

If you intend to travel with the flosser be aware of the different power requirements internationally.  As a quick reference guide:

  • Printed on base/plug – 100-240V
    • Where can it be used? Globally
    • Do I need a voltage convertor? No
    • Do I need a plug adapter? Subject to country
  • Printed on base/plug – 220-240V
    • Where can it be used? In countries with 200-240V (e.g. most European countries, NOT US/Canada)
    • Do I need a voltage convertor? Yes if the voltage of the country you are travelling to is less than 220V
    • Do I need a plug adapter? Subject to country
  • Printed on base/plug– 110 Volts 60 Cycles
    • Where can it be used? In countries with 110 volts (e.g. US/Canada)
    • Do I need a voltage convertor? Yes if the voltage of the country you are travelling to is higher than 110V
    • Do I need a plug adapter? Subject to country

Warranty

Subject to change between models and manufacturers, most come with a 2 year (24 month) warranty that will cover any faults that are not as a result of user damage.

An example might be the pump failing to push water through.

You will need to contact the manufacturers respective customer service line but will likely need your original proof of purchase and once accepted arrange repair or replacement of the product.

Where to buy

Due to the size and slightly more specialised nature of the electric flosser, sadly the availability is not quite as great as most other dental products.

You are less likely to see a wide range in your local supermarket, but chemists like Chemist Warehouse do offer them.

Many manufacturers offer their own online stores and then there are the other retailers like Shaver shop and Amazon who offer a wide portfolio of products.

I have to suggest Amazon as the ‘best’ option given their very competitive prices, broad range and rapid delivery options.
