Best Cordless Water Flossers On The Market: Top 10 Cordless Water Flosser Reviews
1. Best Overall Cordless Water Flosser: Waterpik Cordless Advanced (WP-560)
The Waterpik Cordless Advanced is our top choice, and this comes as no surprise considering that Waterpik is a is famous for their high-quality water flossers. The Waterpik Cordless Advanced has three electronically controlled pressure settings—high, medium, and low—ranging from 45 to 75 PSI. It’s a rechargeable model with an internal battery that charges through Waterpik’s new four-hour magnetic rapid charging system. One full charge should be enough to give you a week of use. A convenient LED indicator also tells you when your flosser needs to be recharged.
The Waterpik Cordless Advanced will give you around 45 seconds of flossing time with one fill of its water reservoir. It comes with four flossing nozzles, namely two Classic Jet Tips, one Waterpik Plaque Seeker Tip, and one Waterpik Orthodontic Tip; the Classic Jet Tips are for general use and cleaning, the Plaque Seeker Tip is used to remove plaque from implants, bridges, crowns, and other appliances, and the Orthodontic Tip was designed to clean around orthodontic appliances like braces. These tips can be rotated 360 degrees, giving users fast, thorough, and deep cleaning no matter the angle.
This model is waterproof so you can even use it in the shower. It has global voltage compatibility, making it an excellent travel option. Waterpik also designed this model to be extra quiet so you can use it anywhere and anytime with no hesitation.
Note that the Waterpik Cordless Advanced has a non-replaceable internal battery. You have to remember to unplug your flosser when it’s done charging since frequent overcharging will reduce its battery life, and a depleted battery is something you definitely want to avoid with a cordless model. With that said, as long as you’re diligent about unplugging your flosser, you’ll be able to enjoy it for years to come.
- Three pressure settings
- LED indicators for battery life and charging
- Comes with four multi-functional, 360-degree rotating nozzles
- Four-hour magnetic rapid charging system
- Global voltage-compatible
- Quite pricey
- Non-replaceable internal battery can pose problems
2. Runner-Up For Best Overall Cordless Water Flosser: Waterpik Cordless Plus (WP-450)
If you don’t need the bells and whistles of the Waterpik Cordless Advanced, then the Waterpik Cordless Plus is the choice for you. The Waterpik Cordless Plus is the predecessor of the Cordless Advanced we reviewed earlier. Despite being an older model, it has the same quality you can expect from a Waterpik product and is still a great value proposition.
The Waterpik Cordless Plus has in-handle dual-pressure control. You have high and low water pressure settings, ranging from 45 to 75 PSI. Its water reservoir has a capacity of 45 seconds of flossing time, similar to the Cordless Advanced.
This model comes with four different tips, namely two Classic Jet Tips, a Plaque Seeker Tip, and an Orthodontic Tip. These are the same tips that come with the Waterpik Cordless Advanced, so your mouth will get the same thorough and intensive cleaning with this model. These tips also rotate 360 degrees, making flossing as effortless and easy as possible.
The Waterpik Cordless Plus is a rechargeable model. The first time you charge this water flosser should be for 24 hours and you’ll be able to get one to two weeks of use per charge, depending on how frequently you floss. When the battery is running low, leave it charging for 8-10 hours. Waterpik advises users to unplug this flosser when it’s done charging, so as not to drain the battery completely. Overcharging or constantly draining the battery can both reduce battery life quickly.
We wish that this water flosser had some kind of charging or battery life indicator. That would eliminate the guesswork for users regarding how much they have to charge their flossers.
Nonetheless, the Waterpik Cordless Plus presents so many advantages that definitely make it a worthy investment.
- Adequately strong water pressure
- Compact and lightweight
- Comes with a variety of four different flossing tips
- 360-degree rotating tips
- Good battery life
- No charging indicator
- North American voltage-compatible only
3. Best Battery-Powered Cordless Water Flosser: Panasonic Dental Water Flosser EW-DJ10-A
Panasonic is known for a variety of household appliances and products, but water flossers probably don’t come to mind when you think about where Panasonic excels as a company. However, they really hit it out of the park with the Panasonic Dental Water Flosser EW-DJ10-A, being our top pick for a battery-operated cordless water flosser.
One of this flosser’s most notable features is that it can collapse to half its size, making it the perfect option for frequent travelers. It has two-speed pulse settings: high-speed pulse for general flossing and cleaning, and lower-speed pulse for sensitive gums, or even for use by children. Despite its small size, its water reservoir can give you about 40 seconds of flossing time.
This Panasonic model is completely waterproof, making regular cleaning and maintenance a breeze. Each part can be washed under running water, and we recommend that you do this to avoid any build-up of grime or bacteria in your flosser.
Because this Panasonic model is so compact and lightweight, it only requires two Double-A (AA) batteries to operate. This flosser is very energy efficient so you won’t have to replace the batteries often. Even heavy users who floss more than twice a day will only have to change the batteries around twice a month.
The small size of this water flosser does come with some trade-offs. It can be hard to clean this product and mold can build up if you aren’t diligent about maintenance. The water pressure also tends to decrease when water is running low in the tank, so you’ll likely have to refill this flosser to get the level of cleaning that you want.
But these are little things that we’ll gladly live with considering the value that this water flosser offers.
- Compact, collapsible design is perfect for travel and storage
- High-speed pulse is very powerful
- Only two Double-A (AA) batteries required
- Doesn’t come with extra nozzles
- Can be difficult to clean
4. Runner-Up For Best Battery-Powered Cordless Water Flosser: Waterpik Cordless Freedom (WF-03)
The Waterpik Cordless Freedom is unique among Waterpik products for being one of their few battery-powered models. It’s another great option if you favor a battery-powered device over a rechargeable one.
The Waterpik Cordless Freedom is powered by three double A (AA) batteries, and Waterpik recommends that customers use only alkaline or NiMH batteries. Your purchase already comes with three free batteries so you just have to stock up on extras of your choice.
This water flosser comes with three flossing nozzles, namely two Classic Jet Tips and one Orthodontic Tip. While not as varied as the ones that come with newer Waterpik models, these tips are more than enough to cover most users’ oral hygiene needs. The Waterpik Cordless Freedom also has in-handle dual-pressure control. The lower pressure setting is at 45 PSI, while the higher setting is at 75 PSI. You can expect to get around 30 seconds of flossing time with one fill of the water reservoir.
This model has the added bonus of being waterproof so you can safely use it in the shower. It also comes with a microfiber travel bag for greater convenience. A travel water plug is included in the package so that your flosser won’t leak during transport.
Because the Waterpik Cordless Freedom isn’t a new model, it hasn’t benefited from Waterpik’s design upgrades as much as other flossers. It’s not the easiest flosser to hold one-handed and using it has a bit of a learning curve. It would’ve been nice to have separate power and water pressure buttons instead of having them all in one slider, since it’s easy to miss the middle setting with this design.
All in all, though, the Waterpik Cordless Freedom is still a solid choice for those who want a battery-powered cordless water flosser.
- Comes with three multi-functional flossing tips
- Double-A (AA) batteries are affordable and accessible
- Detachable water tank
- Comes with a travel bag and travel water plug
- Can be difficult to operate one-handed
- Relatively small water reservoir capacity
5. Best Cordless Water Flosser For Multiple Users: Zerhunt Cordless Water Flosser
Zerhunt is relatively new to the market but their cordless water flosser is already making waves. The Zerhunt Cordless Water Flosser is our recommendation for those looking for a flosser that the whole family or multiple users can use.
The Zerhunt Cordless Water Flosser has three modes—Normal, Soft, and Pulse Modes—ranging from 30 to 100 PSI. It comes with a two-minute auto-timer that shuts off the flosser when it’s not in use to save battery life. One fill of its detachable water tank can give you around 50 seconds of flossing.
This water flosser is a rechargeable, USB-compatible model. Charging only takes four hours, and one full charge can give you up to two weeks of flossing. You can also use this flosser in the shower since it’s waterproof.
The Zerhunt Cordless Water Flosser’s most notable feature is its six color-coded, 360-degree rotating flossing nozzles, making this the perfect choice for families or multiple users. You can assign a color per user and never mistakenly use someone else’s nozzle.
Note that the position of the on/off switch on this flosser can be problematic for some users. Because the switch is so high up on the flosser’s neck, it’s easy to accidentally turn the flosser on or off when you don’t intend to. It also takes some practice to get used to this model and to really get the water to spray where you want it to.
But don’t let these minor concerns discourage you from getting this great product, especially if you have multiple users in mind.
- Comes with six color-coded, 360-degree rotating tips
- Quick charging and long battery life
- Three water pressure settings
- Global voltage-compatible
- Poor placement of the power switch
- The highest pressure setting is too strong or messy for some users
6. Best Cordless Water Flosser For Travel: QQCute Portable Oral Irrigator
Don’t be fooled by the name—this is a powerful device! One charge of the QQCute Portable Oral Irrigator can give users up to two weeks of use, depending on flossing frequency. That’s enough to last a short trip even if you forget to pack the charger. This flosser’s USB-compatibility is another convenient feature since most other devices these days are also USB-powered; you can charge this water flosser anytime and anywhere—with a power bank, a wall adaptor, in the car, or even with a laptop if you really wanted to. All of that, plus its global voltage-compatibility, really make this a must-have for any traveler.
Pressed for time? This product’s mode memory function will revert to the last mode you used so you won’t have to switch through the settings. It’ll essentially set your favorite mode, whether Normal, Soft, or Pulse, as the default flossing mode. This flosser will also help you save time with its flossing capacity of about 50 seconds. You can cover your whole mouth without having to refill the reservoir. This will save you time and effort, especially with a fully-rotating nozzle that reaches all the spaces you need.
This cordless water flosser is travel-friendly even in its size, which is why the buttons can feel a bit cramped and poorly spaced. For users with large hands, this will just take a bit of practice to get used to.
But for anyone who’s always on the go, there’s no better option than the QQCute Portable Oral Irrigator.
- Compact and lightweight
- USB-compatibility makes for easy charging
- Fully-rotating nozzles
- Poor button layout
- Only comes with one extra flossing nozzle
7. Best Portable Cordless Water Flosser: Mospro Professional Oral Irrigator
If portability ranks high on your list of important features in a water flosser, the Mospro Professional Oral Irrigator is our pick for you. This product is a rechargeable, cordless water flosser with Normal, Gentle, and Pulse pressure settings. You get 30 to 100 PSI of flossing power depending on the mode you choose.
This water flosser comes with four color-coded, 360-degree rotating nozzles that can give all areas of your mouth a deep clean. And speaking of cleaning, this model’s water tank is completely detachable, allowing you to keep your flosser just as clean as your mouth.
The Mospro Professional Oral Irrigator is our number one recommendation for portability because of its very light weight and compact size. This flosser is also waterproof and designed to prevent water leakage, ensuring that you can safely bring it around and use it in any setting. Battery life is important for portability, and you can expect to get 7-10 days of use from this model before having to recharge. If you accidentally leave your charger, you’ll still be able to get a few flossing sessions out of this product. It can also charge via USB so you can recharge with just about any USB-compatible device you have on you.
This model’s portability came at the expense of some of its water capacity. Most users will probably have to refill the tank for a complete flossing session, which can prove more cumbersome than expected since the tank can be tricky to detach. You also need to get acquainted with this flosser’s button layout, or you might end up spraying your walls or making a mess on the sink with a wrong button press. However, we still think that this is the best portable cordless water flosser available today.
It just takes a little practice to get the most out of this investment!
- Fully detachable water tank is great for cleaning and hygiene
- Comes with four color-coded, 360-degree rotating nozzles
- Compact and lightweight
- The water tank can be difficult to remove
- Relatively small water reservoir capacity
8. Best Portable Cordless Water Flosser On A Budget: ToiletTree Products Poseidon Oral Irrigator
The ToiletTree Products Poseidon Oral Irrigator might be on the more affordable end of the spectrum, but it still packs a lot of features and gives users excellent bang for their buck. It’s a great all-rounder and a worthy addition to anyone’s oral care collection.
One of the best features of this water flosser is its portability. It has a slim and compact profile and comes in at just under a pound, making this the perfect option for those with small bathrooms or those who like to travel light. Its base takes up less than 3 inches of space and we imagine that this can fit anywhere you choose. It’s waterproof and has global voltage-compatibility, so you can take it everywhere and stay consistent with your oral hygiene.
This water flosser is a rechargeable model that takes around 8 hours to fully top up. You should be able to get a week of flossing on one charge. To conserve battery life, this model also comes with a built-in automatic shut-off feature that will power down the flosser after two minutes.
A quick tip release button unlocks the flosser tip from the body with one press, making switching between tips effortlessly easy. The ToiletTree Poseidon’s tip sprays out an ultra-fine 0.6mm stream in three pressure settings: Normal, Soft, and Pulse, which range from 40 to 80 PSI. ToiletTree promises 60 to 80 seconds of flossing time, but we found it to be closer to 30 to 50 seconds in actual use. Still, that’s not a bad range since it’s within the average for most cordless water flossers.
The ToiletTree Poseidon’s water reservoir design is what we find a little lacking. You have to keep the flosser upright as you go because its tube tends to pick up air, especially when the tank is less than half-full. This means that most users will probably have to fill the tank more than once to get that truly clean and fresh feeling. That aside, this is still a great water flosser with so much to offer.
It’s also so affordable that there’s no risk trying it out.
- Very lightweight and compact
- Automatic shut-off feature to conserve battery life
- Global voltage-compatible
- Comes with only two tips
- Likely to require refills for thorough flossing
9. Runner-Up For Best Portable Cordless Water Flosser On A Budget: SmarToiletries Professional Rechargeable Oral Irrigator
The SmarToiletries Professional Rechargeable Oral Irrigator is another solid option for those who want a quality cordless water flosser without breaking the bank. This water flosser has three cleaning modes ranging from 40 to 90 PSI. Normal mode is the highest pressure setting and recommended for experienced users. The soft mode was designed for children and users with sensitive gums. Massage mode stimulates and massages the gums for improved blood flow. A convenient LED indicator lets you know which mode is active.
This model comes with four Jet Tips, making this suitable for multiple users or just giving you extras to keep in stock. Its water reservoir has around 45 seconds of flossing capacity. It has a built-in SmarTimer that automatically shuts off the flosser after a two-minute cycle, helping preserve battery life.
This SmarToiletries cordless water flosser is waterproof, rechargeable, and USB-compatible, all of which really add to the portability of this model. It has great battery life and you can expect two or even three weeks of use before you have to recharge it. It’s not as bulky as other cordless water flossers so it’s easy to store and also easy to hold and operate.
Unfortunately, the lid or flap of the reservoir isn’t very sturdy, making this model prone to some leakages. However, this won’t be much of an issue with proper use, and the manufacturer can be contacted for parts or unit replacements.
- Compact, lightweight, and easy to carry
- Comes with four flossing tips
- The flossing tips aren’t color-coded
- The water reservoir sometimes leaks
10. Best Lightweight Cordless Water Flosser: Philips Sonicare AirFloss Rechargeable Electric Flosser (HX8211/03)
The Philips Sonicare AirFloss is one of the lightest cordless water flossers around, and that’s because of its unique flossing technology that uses a mixture of air and water to clean users’ mouths. The Philips Sonicare AirFloss is the lightest model on this list, but it’s definitely a heavy-hitter among cordless water flossers.
This water flosser’s most notable feature is its combination of air and micro-droplet technology to remove plaque, dirt, and debris from users’ gums and teeth. While most water flossers rely solely on water, the Philips Sonicare AirFloss pumps out air together with droplets of water. Because of this feature, it operates differently from other water flossers. The air and water don’t come out in a continuous stream. Rather, they come out in single bursts each activated by a button press.
This flosser comes with a guidance tip that fits into the grooves between your teeth so you know where to direct the flosser each time. To use this flosser, you align the guidance tip with the space desired and then press the activation button to get one burst. You then move the guidance tip from one space to the next, pressing the activation button each time you get to a new space. A new auto-burst feature allows users to hold down the button instead, and the flosser will proceed to burst every second.
This model’s reservoir can hold enough water or mouthwash for two flossing sessions. You get a lot more control with this water flosser than other models, so flossing time and speed will really vary from user to user. This is a rechargeable model that’ll give you a solid battery life of about two to three weeks.
Note that the design of this product’s reservoir makes it difficult to dry out, which could potentially cause a mold build-up in your flosser. It’s not the easiest flosser to clean and you might have to get a little creative to get all the water, bacteria, and grime out. Some users also find the burst sensation uncomfortable. You can’t change the burst pressure and you might not like the sensation of air compared to pure water.
However, if you’re in the market for a lightweight cordless water flosser that’ll give you a lot of control over your flossing, this is still an excellent product to consider.
- Extremely lightweight
- Users can control each burst
- Global voltage-compatible
- Guidance tip improves ease of use
- New auto-burst feature
- Difficult to clean
- Only one pressure setting
Buyer’s Guide: What Should You Look For In A Cordless Water Flosser?
Water flossers might all look the same but it’s the little details that really separate ‘must-haves’ from the ‘must-avoids.’ Here are some features that you should look out for when choosing a cordless water flosser.
Water Pressure Settings Or Modes
The ideal cordless water flosser should have multiple modes or pressure settings. You can’t expect to have as many settings as the more powerful countertop models, but most cordless water flossers can still offer some variation in water pressure
Stronger modes, on the other hand, are useful for really getting into those spaces between your teeth and removing tough plaque, dirt, and debris.
Water Reservoir Capacity
Since we’re looking at cordless water flossers, it’s important to remember that these won’t have the same tank capacity as countertop models. It’s a trade-off that has to be made for better portability. One fill of the tank of a cordless water flosser will usually give you around 30 to 45 seconds of flossing time, depending on the pressure setting that you use.
Nozzles Or Attachments
Different brands and models have their own flossing nozzles, also called ‘attachments’ or ‘tips.’ It is safe and hygienic for more than one person to use the same water flosser since the nozzles don’t touch users’ gums or teeth. Most cordless water flossers come with multiple flossing attachments of the same kind, meaning that these nozzles don’t vary in functionality. They will, however, still get the job done and allow you to replace them as needed.
Power Source, Battery Life, And Charging
Cordless water flossers are either rechargeable or battery-powered. The choice of power source is ultimately up to you, so we’ll outline the pros and cons of both options here.
Rechargeable Water Flossers
With a rechargeable model, it’s important to note that not all internal batteries and chargers are made equal. Some batteries can last up to two weeks on just one charge, while others will require more frequent charging. Charging times will vary depending on the manufacturer and model.
Some models have to be plugged into a wall outlet or socket, while others are already USB-compatible. Keep these considerations in mind and see what fits best with your lifestyle.
Battery Powered Water Flossers
Battery-powered devices are becoming less popular these days, but there’s a reason that they persist even with more advanced tech. A battery-powered water flosser will always be ready to go as long as you have spare batteries. You won’t have to wait for your flosser to charge.
You will also never have to worry about voltage compatibility when you’re traveling with your flosser.
Of course, the downside to this is that your flosser will be unusable if you don’t have any batteries. Just remember to stock up on batteries so that you can easily avoid this problem.
A cordless water flosser is perfect for travel, allowing you to maintain your dental hygiene even when you’re on the go. Most cordless water flossers come with travel cases where you can store your flosser, charging cables or batteries, and some extra tips or nozzles.
Compact and lightweight models make for the best portable water flossers. A model that charges via USB is also ideal for travel so that you can avoid any voltage compatibility issues.
Flosser Design and Ergonomics
A good cordless water flosser should feel comfortable in the hand and easy to hold. It shouldn’t be too heavy, or that would defeat the purpose of having a more portable water flosser. Most models these days were designed to allow for one-handed operation.
Another key element of good water flosser design is the layout of the buttons on the flosser handle. The buttons should be easily accessible and within reach of your fingertips. The buttons should also have intuitive spacing so that users don’t accidentally press the wrong one in the middle of flossing. A button for pausing water flow is also a great feature that gives you more control over your flossing and helps you avoid making a mess on the bathroom counter.
