Water flossing is an easy way to improve the overall health of your teeth and mouth. It is quick, it’s easy, and it produces rapid results. Plainly put it will make your teeth look better.
Flossing is great for cleaning between teeth, but some people are uncomfortable with using waxed string because they have to say it backwards and forwards between their teeth and this can be uncomfortable. Others find that using string makes their gums bleed, and this is one of the reasons why water flossers have become so popular over the years. They are much more gentle and more comfortable than using string, and some research has shown that they can reduce bleeding gums by up to 93%.
Not only that, but they are proven to be effective. Clinical studies of the Waterpik brand found that water flossing was 51% better at reducing gingivitis, twice as good at reducing bleeding from the gums and 29% better at removing plaque than dental floss. They have even found approval with the American Dental Association, so their benefits are indisputable now. The only question left now is which one should you buy?
The one big drawback with most water flossers has been that they need to be plugged in somewhere. Electricity and bathrooms don’t mix well, and many traditional flossers (countertop) are not very portable, so if you travel a lot it can be a pain having to bother with plugs and cables when you want to floss. That’s why somebody came up with the bright idea of the cordless water flosser. But what should you look out for when choosing one?
Things to think about when buying cordless water flossers
- Large enough water tank capacity?
- Built-in battery or removable?
- How long does the charge last?
- How long before the battery needs replacing?
- Strong enough water pressure?
- How portable is it?
Top cordless water flossers of 2018
Waterpik WP-560 Cordless Advanced Water Flosser
This is our top buy for 2018, partly because the American Dental Association has formally approved it. We like it because it has 3 pressure settings, can hold enough water for 45 seconds of use at a time, and comes with 4 flossing tips (2 standard, 1 for plaque and 1 for orthodontics).
It’s quiet to use and can charge up in just 4 hours because it uses inductive charging (but do remember to disconnect it after it’s fully charged, or you may damage the battery. Some units have failed because of this so it’s something to be very conscious of the unit controls water pressure electronically and you get a choice of 3 settings: low, medium, and high pressure, which means your teeth get blasted at between 45 and 75 PSI.
If you like to floss in the shower, then you will be happy to know that the Waterpik WP-560 is waterproof and won’t mind if you get it wet. Doing your teeth in the shower is a good way to get the job done without having to clean up any mess and can also save you time in the morning.
The package includes a drawstring pouch so you’re not just tossing it into your suitcase ‘naked’ and Waterpik has thoughtfully included a plug to stop it leaking over your clothes when the cleaning tip is removed.
In use it’s very pleasant. It’s effective at what it does and always leaves the mouth feeling very clean. The only slight criticism we could level at it is the battery life. Using it for a minute a day will get you 7 days of usage before you need to recharge it. Also, the battery is built-in so if it fails you would need to dismantle it to change it, but having said that, the WaterPik WP-560 comes with a 2-year warranty, so getting a replacement if it fails should be easy.
It’s a pleasure to use every day, but at 20 cm tall and with a chunky body it might be a bit too much for small children to handle without supervision. Aside from that, we recommend the WP-560 as the current supreme champion among portable flossers for its excellent overall performance.
Waterpik WP-450 Ultra Cordless Plus Water Flosser
Another Waterpik slip into the number 2 position. Like the WP-560 it comes with 2 classic jet tips, the plaque seeker tip, the orthodontic tip, and a charger. The difference with this model is that it has 2 pressure settings instead of 3, so you can switch between low (45psi) and high (75psi) water jet strengths.
This one charges with a socket instead of the magnetic method base of its big brother, and it has a nice ribbed rubber body which is easy to grip. The 200 ml water tank is good for 45 seconds of flossing time, which seems to be the amount of time chosen as a compromise between a good clean and maximum portability. When you think about it, they could have given the unit a 1-liter tank but you would struggle to lift it!
Refilling the tank is easy. You just pop open the sealed flap and put it under the tap. You needn’t worry about splashing because the whole unit is sealed, so no water will get to the electrics. That said, don’t let it sink in the bath. You don’t want to risk sending it to a watery grave.
The tips slide in to place with a click with ease, and you can remove them again just by pressing the button. Tips can be locked into one of 8 positions, whichever suits you best, so it’s held at the angle you prefer.
Charging the Waterpik WP-450 takes 24 hours, which is good for about 14 time uses before the battery completely gives up. Because it takes a long time to charge, you’ll want to make a note in your diary each week, so you don’t get caught out by a flat battery.
In use, the unit does a great job of cleaning along the gum line on one tankful, but if you have orthodontics, then you may need to refill halfway through to finish the job.
All in all, this is a great cordless water flosser for those on the move.

Waterpik WP-360W Cordless Water Flosser
The WP-360W does a good job of flossing well at a reasonable price. It comes with just 2 tips, one for low pressure and one for high pressure. We found that the unit lasts for 1 week if used twice a day, but some users have reported that it can last longer, even up to 3 weeks if it’s used only once a day. Waterpik recommends that you recharge the unit between uses, so this shouldn’t be a problem. The unit isn’t very bulky, so it won’t take up much room on the bathroom countertop.
The water tank holds 150 ml, which is only three quarters of the size of the WP-450 and WP-560, which means you only get about 30 seconds of flossing before you need to fill it once more. The flosser tip can be rotated through 360° which means you can point it towards your back teeth without having to twist your wrist around in an uncomfortable way. It’s really good for getting to the areas that are hard to reach with normal floss, the areas where plaque can build up unseen.
Overall this flosser is a very decent and competent unit, but it’s relegated to 3rd position because it doesn’t have quite as many features as the other top two. The WP-560 has a larger tank, comes with 4 tips and has a faster charger and the WP-450 comes with 2 tips and has a 24-hour charger. Both of these have a bigger tank than the WP-360W.
Waterpik WF-03 Cordless Freedom Water Flosser
Waterpik is doing a great job of taking the top positions isn’t it? This is another one of their offerings, and it’s another good design which is a competent performer and handy for travel. It comes with 3 tips, 2 classic jet and 1 orthodontic tip, which should make it popular among students with braces.
As the flosser is powered with AA batteries there is no problem in getting it charged up if you take it to other countries. You can either put standard batteries or rechargeable in it, so you will never be caught short.
As you may know, for most of the flossers of Waterpilk, if you buy your model in North America, please be advised that you shouldn’t use it outside the country due to voltage issues. However, the WP-03 has an advantage here since the replaceable AA batteries can solve this problem properly.
It’s waterproof as you might expect, making it handy for usage in the shower, and it has 2 pressure settings (45 and 75PSI), so you can choose the one that’s most comfortable for you, or switch between the two, with full pressure in one part of your mouth and lower pressure in a more sensitive area.
The tip rotates though 360° which is great for getting into hard-to-reach areas.
The reservoir holds enough capacity for about half a minute of use, which does feel a little bit short if you’ve tried one of the 45 second models. But it’s enough for a swift rinse if you’re away from home and on the move and does enough after a meal to leave your mouth feeling clean and refreshed.

Panasonic EW-DJ10-A Portable Dental Water Flosser
At last we have a water flosser that isn’t made by Waterpik! The most impressive selling point of this model is its outstanding design for space-saving. When the unit is empty, the body pushes down into the empty reservoir which saves on storage space. In the fully extended position you just fill the reservoir with lukewarm water, and off you go.
Power is provided by a pair of AA batteries, another plus point, so you have the freedom to use rechargeable or single use as you wish. You do have to supply them yourself though as they are not included in the box. And on that note, what also isn’t included are extra nozzles. You just get one jet. And there is no travel pouch either. Not a big deal of course, but something to keep in mind.
Like all of the Waterpik products it’s waterproof so you can take it in the shower without worrying about hurting it. It has a turnable nozzle and two power settings.
The tank holds 160 mL which again, is enough room for about 30 to 40 seconds worth of water, which puts it at about the average for this type of device.
It looks as if the Panasonic EW-DJ10-A is mainly intended for people who travel a lot, or maybe people who like camping in the great outdoors, because it is very portable.
The unique design certainly outshines any other flosser on the market, because it’s the only one out there that can collapse into itself and save space. On its own that isn’t enough to push it to the top of the best-buy list, but it is a great feature that makes it worth serious consideration.

ToiletTree Poseidon Portable and Cordless Water Flosser/ Oral Irrigator
Here is another non-Waterpik product and one from a brand that isn’t well-known. This offering is a sturdy unit that looks pleasing to the eye with its hourglass shape, although that shape does feel big and bulky in the hand.
It has 3 pressure settings called normal, soft and pulse. They deliver 40, 60, and 80 PSI respectively for periods of use of 60-65, 70-75 and 75-80 seconds. A power-saving feature turns it off after 2- minutes to minimize battery wastage, but this seems a bit pointless as you’ll have to stop to refill the tank halfway through anyway!
The water pulses come at 1800 times a minute, which is enough to dislodge food and shift plaque from along the gumline.
It weighs about 500g and is powered by rechargeable lithium-ion batteries to give about a week’s worth of use. On a full charge it should last about a week, and charging is via its USB port, which is a convenient option to have when you’re on the move.
It’s another water-resistant design which means that if you want to use it in the shower you can.
The motor is fairly quiet and it’s easy to replace tips quickly at the touch of a button. The tank holds 150 ml of water which is enough to get you through around 40 seconds of use.

MOSPRO Professional Cordless Water Flosser / Dental Oral Irrigator
This MOSPRO water flosser has a pleasant design that feels comfortable to use. The water tank is transparent, so you can check that it’s filled to the limit of its 200ml capacity. The tank is removable, like some other models, but unlike them it can be opened, which makes cleaning out any limescale deposits and bacteria very easy. Instead of just sluicing water in, you can actually scrub to make sure that nothing nasty is making its home there.
It’s another model designed to be waterproof, so you shouldn’t get any leaks. It also boasts 360 degrees of nozzle rotation and 3 pressure modes, named normal, gentle, and pulse. These can deliver jets of water at between 30 and 100 psi.
The pressure might be a bit mild for some people, but it does give a decent clean. The water reservoir will empty after about 20 seconds.
It can do all this for about 7 days per charge and can be recharged via USB. It’s lightweight and you get a storage bag for your travels, so you will probably need to refill it a couple of times to do the job properly.

Zerhunt Professional Rechargeable Portable Dental Water Jet
The Zerhunt is another relatively unknown name compared to the likes of WaterPik, so perhaps because of that they have tried to include enough features to attract the interest of potential customers.
It’s a nice-looking device with a profile that pinches in the middle to fit the hand and spreads out at the bottom to accommodate the water tank. It can hold 200 ml which is good for about 40 to 50 seconds of flossing.
It also comes with 3 tips which are identically color-coded so that different members of the family can have their own to use.
To fill the tank, you don’t need to detach it. Just open the flap at the bottom to fill it with water (This tank is also removeable). The design is such that for the water to be fed into the pump it has to enter a tube which dangles down inside from the body. This means that when you’re flossing you have to keep the Zerhunt upright, otherwise it runs dry. Not a huge inconvenience, but something that you have to make allowances for.
It’s got 3 different modes. Soft, Normal, and Pulse. As you’d expect, the difference is to do with the water pressure and the amount of pulses that the unit generates. It can pulse at up to 1700 times a minute and combined with the 360° rotating nozzle it does a good job of getting the cleaning jet to blast debris from between the teeth.
This model can hold charge for up to 2 weeks depending on usage and charging takes just 4 hours. It can also handle international voltages so it’s very portable.

Pure Daily Care Aqua Flosser Professional Cordless Oral Irrigator
Pure Daily Care has produced a portable water flosser that’s designed to be used by the whole family, which is why they included a total of 4 flossing tips, each with its own color. They also included a stainless-steel dental toolkit, but unless you are a dentist it might be best to exercise caution when poking around inside your mouth with tools that you are not used to using! The mirror tool is safe and useful of course, but using scrapers is best avoided.
It takes a lithium ion rechargeable battery that can hold charge for more than a week with normal usage. It’s not very heavy and it is waterproof, as many of these devices are. And in common with them also the tip rotates so that you can attack the teeth from different angles.
It fits in the hand nicely and is easy enough for children to hang onto as well.
Its 3 modes are the usual Normal, Pulse, and Soft, and they relate to different waterjet pressures, with Pulse adding intermittent pulses to the water stream to help dislodge material from between the teeth.
The tank will hold 150 ml, so you will need to refill it once or maybe twice to finish your whole mouth.It can be charged with USB which is very convenient for travelers, as you could just plug it into your laptop if you couldn’t find a socket.

VAVA Cordless Water Flosser, Professional Dental Oral Irrigator
Vava is another new brand that offers 3 settings: pulse, low, and normal, and includes 3 jet tips (3 color-coded). It can clean for 50 seconds from its 200ml water tank and uses a lithium battery.
One of the advantages of this model is its battery life, it’s claimed to have a 24 days use when it’s fully charged!
Its nozzle rotates 360°and pulse frequency goes from 1,400 to 1,800 times a minute, with water pressure 30–100 psi.
The water reservoir is removable and easy to clean. It’s another competent performer and worth a look if you aren’t too concerned about buying a well-known name.

Overall, the Waterpik is a worthy winner, but all of the featured models on our list are capable of performing well.
Waterpik has a well-established name and is considered to have excellent customer service, so consider their products if you want to be sure that the help will be there if your unit ever breaks down. Customers report that they are very responsive, and that’s not something you can be totally sure of if you trust a brand that hasn’t been around as long.
In addition, the traditional brands like Waterpik sometimes will offer some not expensive but value-added accessories that you definitely needed – for example, the Whitening Water Flosser Refill Tablets.
It is undeniable that these thoughtful and practical gadgets often help them win the favor of consumers.
