The Sonic-Fusion has been updated, there is now version 2.0.
Learn more about it in our hands-on review of the Waterpik Sonic-Fusion 2.0 flossing toothbrush.
Conceptually, I like the idea of the Sonic-Fusion.
In reality, I am a bit disappointed. It has failed to wow me.
The toothbrush is satisfactory. It cleans the teeth, but it makes an irritating noise. The battery life is poor.
You are much better off buying a separate electric toothbrush and water flosser, as discussed in my article on the best electric toothbrush and water flosser combo.
- Toothbrush and water flosser combined
- Stylish design
- Timer and pacer encourage brushing for the recommended time
- Choose between 10 different pressure settings
- American Dental Association (ADA) approved
- 3 year warranty
- Toothbrush battery life is poor
- Combines two products into one – conceptually great, poor execution
- Not suitable for all – only 1 style tip
- The water flosser is not portable
- Expensive (see other choices)
Where to buy the Waterpik Sonic-Fusion
Here are some of the current prices and retailers, in addition to Waterpik’s own online webshop stocking the Sonic-Fusion.
It’s always worth checking eBay too.
Consider these other water flossers
The Sonic Fusion is quite unique, there isn’t really another product quite like it.
Whilst Waterpik doesn’t make the best electric toothbrushes, they do make the best water flossers.
If you want the convenience of water flosser and toothbrush as one package, then the Waterpik Complete Care 9.5 (view on Amazon) would be a great alternative. The separate brush and flosser handle are more convenient.
Either alternative is likely going to be a little more cost effective than buying the Sonic-Fusion.
Waterpik Sonic-Fusion in-depth review
If you have ever visited the dentist, you will likely have heard them say, make sure you brush properly and floss. It is a routine saying, but it is said for good reason.
Brushing your teeth alone cleans just 60% of the tooth surfaces, leaving some 40% untouched by the bristles of the toothbrush.
That 40% is the side of the teeth or what professionals call interdental spaces.
This then is where you need to make use of interdental brushes, dental floss or you can use a water flosser.
All of these products can reach into spaces and under the gumline in ways, regular tooth brushing, even with an electric toothbrush cannot.
Using floss and brushes can be awkward and may mean you skip the process entirely. This is where the powered water flosser can become really useful.
The pressure of the water cleans away plaque and debris and helps you maintain a really good standard of oral health with a convenience not achieved by floss and brushes.
The Sonic-Fusion is a toothbrush and water flosser blended into 1 product, a flossing toothbrush.
It is designed to be a more convenient and practical option for you to help take care of your teeth and gums.
Variants of this water flosser – Waterpik Sounc Fusion SF-01 vs SF-02
Waterpik often makes a standard and professional variant of water flosser units they manufacture.
I am not entirely sure why they do this as the differences are always very slight, but Waterpik has made 2 different models of the Sonic-Fusion.
There is the SF-01 and the SF-02.
The SF-02 is the ‘Professional’ model.
The differences between these models is very slight, but the differences are:

It is the SF-02 ‘Professional’ model that I am reviewing here.
Subject to price, the SF-01 could be the better buy. There are so few meaningful differences here.
I will refer to the SF-01 for the sake of comparison throughout, should the situation change.

Design, usability, clean & general use
White, orange and blue are the stand out colors on the box of the Waterpik Sonic-Fusion.
It is fair to say, it catches the eye.
There is quite a lot of information on the box. The key features, functions and box contents are highlighted in both English and French language.
The box is a fair bit larger than the average toothbrush box, primarily because this toothbrush comes with a base unit that is the water flosser.
As you will know by now, this is not your conventional electric toothbrush or a water flosser, the two have been combined into this water flossing toothbrush.
What you get in the box depends on what variant you opt for.
It is the SF-02 Professional model that I am reviewing, in the black with copper color.
As you will see in the ‘variants’ section of this review, there is little difference between them ultimately.
I have listed what is provided in the ‘what’s in the box’ section above.
Placed on a countertop, the unit looks smart.
Where many dental products are white, it is nice to have the choice of black color as an alternative if you choose. The copper accents give it a certain classy look as the additions are subtle.
The whole unit whilst not small is fairly compact considering. It requires only one power socket compared to the two sockets and additional countertop you had purchased an electric toothbrush and water flosser separately.
There are essentially two main parts to this water flossing toothbrush, the brush itself and the water flosser.
If you have seen a water flosser before the design of the Sonic-Fusion is very similar, the main difference being rather than a handle with a nozzle mounted on the front you have a toothbrush.
The main unit is of a rounded rectangle design, there are no harsh corners or edges.
Mounted inside the black plastic frame is the electronics, notably the pump that draws the water from the clear 14 ounces (414ml) reservoir that sits on top.
The reservoir has a lid on it. Opening it from the left side, it hinges on the right side, in the middle of the unit, giving you visible access to one half of the reservoir.
The reservoir itself is removable and doesn’t need to remain seated to fill the tank.
Fitting snugly into the base unit, there is a strip of copper colored accenting that runs around the top edge of the base unit where the reservoir fits into.
On the rear of the unit is a US 2 pin power cord which is approximately 4 feet (122cm) long.
Fitted to the cord is a velcro strap to help tie up excess cable.
The unit itself supports 100-240v, so should you travel with it you only need a plug adapter, not a voltage adapter.
On the front of the unit, centrally placed is a hose that feeds the water from the pump and into the brush handle.
This hose is approximately 3 feet (90cm) in length. Therefore at full stretch, you can be about 7 feet away from the power socket.
The hose tucks neatly away into the front of the unit for convenient storage. There is a slight recess in the body of the water flosser to allow the hose to tuck away.
The detachable hose is black in color to match the handle.
Whilst the right side of the water flosser is free of buttons or controls on the left side is a large rotatable dial.
This dial controls the pressure of the water flow when in use.
There are 10 settings to choose from, clearly labeled on the dial.
The numbers are in a copper color and there is a copper ring around the edge of the dial.
Protruding out from the base of the water flosser is a platform if I can call it that.
It is flat on the right and left side, but in the middle is a recess that has been molded to offer a place for the handle of the Sonic-Fusion to sit comfortably in an upright position.
When sat here, the brush is in position to be charged. Providing the unit is connected to power, the brush will charge wirelessly. The LEDs on the front of the brush handle will light up to show it is charging.
On the very front edge is the Waterpik logo printed in copper color.
Just beneath this logo, essentially on the base of the unit, as the plastic sweeps to the underside is an LED that shines blue. This only comes on when the unit is connected to power. Despite thinking it is a power LED, it is, in fact, an LED to confirm that the base unit and the brush handle are communicating wirelessly.
On the very base of the unit are 4 rubber feet that help stop the unit from sliding over the countertop.
When looking at the unit it does look smart and you will notice that the width of the unit it the same at the top and the bottom, but halfway up the body pinches inwards slightly, kind of like a waste line, where the reservoir and water flosser meet.
The SF-01 is the other variant. The design is on the whole very similar, but it is a little more rounded in its shape.
Either model looks smart and would certainly not look obtrusive in any bathroom, even for the most house proud. Gone are the days where you would need or want to hide such items away.
So, to the toothbrush part of this unit then.
The toothbrush is an electric toothbrush, but it is also the handle/nozzle for the water flosser.
With a conventional water flosser there is a handle with a nozzle at the top, in this instance, the toothbrush is the handle and the nozzle is the brush head.
The toothbrush handle connects to the water flosser via a hose that clips into the base of the handle.
You have to have the hose attached to use it as a water flosser, but the hose does not need to be attached when using it as a toothbrush.
The hose clips in securely to the base of the handle and is unclipped by pressing a large circular button located on the back of the brush handle, at the very bottom.
The attachment is designed in such a way that the hose rotates a full 360 degrees, so as not to limit your control and movement of the handle when flossing. That said the nature of having a hose attached does cause a slight resistance when handling the brush.
The handle itself is slightly chunkier than a Sonicare or Oral-B brush handle and is finished with smooth plastic.
There are no rubber grips like you see on some brushes to aid with a secure hold in the hand.
However, on the back of the handle are 9 rows of small raised dots that run the length of the handle and do offer some grip to the fingertips.
The front of the handle has an oval shaped panel, with a copper accent around it.
The panel runs the length of the handle and inside sits the main controls and LEDs for the toothbrush.
Of the 2 main buttons on the handle, the top one is the button that turns the brush on or off.
It is circular, with an LED ring around it that lights up a yellow/green. The word brush sits just above.
Underneath is more of an oval button, that has 4 raised dots on it. Surrounded by an LED ring that lights up turquoise/blue and the word floss just above it, this button turns the water flow on and off.
Both buttons are slightly concave helping the fingertips naturally fall and rest in place.
The LEDs are a nice touch. They make the brush a bit more fun and is an approach I haven’t seen before.
The LED’s are activated when buttons are pressed. It would be useful if the lights were activated when too much brushing pressure is applied or when the quadpacer kicks in, but they don’t.
The LEDs around these buttons are not present on the SF-01 model. Whilst nice, they are not essential.
On the lower part of the panel is a battery icon, with 3 LED’s stacked below it. Each LED shines white light and indicates the battery charge.
Roughly speaking each LED represents 33% battery power remaining. If all three are lit then there is plenty of power. Just the one lit, then a charge will be required soon.
Underneath this is the Waterpik logo.
All wording on the handle is copper in color, matching in with the theme.
At the top of the handle is where the brush head attaches.
A metal tube feeds out from the motor inside the brush handle.
Unlike other brushes, this tube has a small hole in it, through which the water comes if being used as a flosser.
Two brush heads are supplied in the box, they simply attach to this metal tube by being pushed on and clipping into place. There is no need to twist to lock the head on the handle.
When you want to remove the head, you simply pull it off.
With the brush head fitted, you will see that the head leans at a very slight angle and this helps with reaching teeth at the back of the mouth when brushing.
The actual brush head is shaped similar to that you might see on a Philips Sonicare brush. It is not a circular brush head like you get with Oral-B electric toothbrushes.
The head is, however, is about 25-35% smaller than a Sonicare brush head. This is noticeable when brushing and I felt there was a little more maneuverability as a result.
Placed just above center within the bristles of the brush head is a small tube that acts as the nozzle for the water flow.
The bristles are vibrant green color and the nozzle for the water flow is blue.
The bristles feel firmer to the touch than they do when it comes to actual brushing in the mouth, they feel soft.
There are 18 bristle tufts at varying heights to help the head get good coverage over and around the teeth.
A point to note is at the bottom of the brush head is a small plastic ring. With the black and copper unit, you get 1 head with a black ring and 1 with a copper ring.
With the white unit, 1 ring is silver and the other white.
These colored rings are not removable and are designed to make it clear whose head is whose.
Imagine a husband and wife sharing the brush handle, they each have their own brush head. The husband may have the black ringed brush head, whilst the wife has the copper color.
Aside from the travel case, there is no place to store the other brush head when not in use.
Unlike Oral-B and Sonicare who offer a vast array of different styled brush heads, Waterpik offers just the one.
They are sold in packs of two.
This is perfect as it makes the purchasing decision much easier.
The heads should be replaced every three months. Unlike some brush heads that have fading bristles or icons that light up on the handle, there are no reminder systems built into the brush, so it is up to you to replace regularly.
Sealed inside the brush handle are the motor and battery.
Little mention is made about the handles water resistance. I believe it should be fine with the odd quick rinse or splash under the tap, but you may want to avoid using it in the shower or exposing it to too much water. The Nickel Metal Hydride (NiMH) battery should offer just 1 weeks use between charges.
Realistically, this is below the expectation of an electric toothbrush today, particularly at this price point. 2 weeks really is the minimum now.
I am somewhat surprised that a lithium-ion battery is not being used as these are now more popular and tend to be more reliable with better usage times.
Given the price of the unit and the size of the handle, it is surprising you don’t get 3 weeks from it.
The brush offers 3 cleaning modes.
These are not the clean, sensitive, massage, whitening and deep clean style modes you might see on other electric toothbrushes.
In this instance this flossing toothbrush offers:
- Brush and floss
You control each mode by a single press on the relevant button.
Press the brush button once to turn it on and press it again to turn it off.
Press the floss button once and the water will begin flowing out the brush head, press it again to stop it.
To brush and floss, first press the brush button, followed by the floss button. You should now get the idea.
An interesting point to note is that the communication between the handle and the main water flosser unit uses wireless technology. Providing the base unit has power connected, you can technically turn on the water flosser, even if the hose is not connected to the handle.
As the name implies, this is a sonic toothbrush and whilst my experience was satisfactory, it felt inferior to the likes of a Sonicare or Oral-B electric toothbrush.
Whilst the brush cleaned the teeth, I did not get the really clean feeling I do with the major brands. The brushing experience felt a little weak. You may like the more gentle clean it offers.
I almost felt like moving the brush head more rapidly myself to help get what my brain perceives as a better clean.
Once powered on in the brushing mode, the built-in timer is activated. There are two parts to this. There is the 2 minute timer and the quadpacer.
You might be familiar with this, but essentially they are very important and help encourage you and me to brush evenly and for the right amount of time.
At 30 second intervals, there is a slight pause in the brush head motion, which also causes a change in sound. This is your alert to move from one quadrant of the mouth to another.
Once you have cleaned the upper right, upper left, lower right and lower left quadrants for 30 seconds each, the 2 minutes has elapsed and the brush will automatically turn itself off. I do like this feature.
This feature is disabled when flossing. The unit will continue to pump from the moment it is switched on until it is turned off.
Not present in the brush is a pressure sensor. This is much more common now in other electric toothbrushes like the ProtectiveClean 4100 and the Oral-B Pro 1500.
In those brushes with a pressure sensor built-in, it will alert you, usually via a change in sound or some sort of visual alert if you are applying too much force when brushing.
Bristles need essentially only skim the surface of the teeth, you don’t need to scrub.
With this Sonic-Fusion, you will hear the brush staining a little if you do brush with too much pressure but there is no actual pressure sensor built in to offer any other form of alerts.
When powered on, this brush makes a noise which I found rather irritating.
This might sound trivial and I am not trying to find fault with the Sonic-Fusion, but it emits a high pitched whining sound.
Sonicare brushes emit a soft audible humming sound. Oral-B brushes emit a much more mechanical clanking sound. This is somewhere in between but is as loud as Oral-B brush in my opinion.
I could live with it for sure. It is just a very different sound to all other brushes I have tried.
I am not sure why it is so loud, compared to all other sonic brushes that are so quiet. Perhaps it is to do with the water flossing element?!
When used as a flosser, the sound is much more bearable. The unit inevitably makes a noise as there is a pump working away, but all things considered, it is fairly quiet.
It is a bit strange using a toothbrush as the tool to floss your teeth.
Maybe it is because I am used to the smaller handles and slimmer nozzles found on most other water flossers, but using a toothbrush handle is a bit more clunky in a way.
The more I used it, the more I got used to it, but it still felt a bit odd and I didn’t feel I was able to control the water jet in quite the same way as I could with a regular water flosser.
For me, the brush head restricts the accuracy and pinpointing element you have with the smaller nozzles on classic water flossers.
Even when you are using the flossing mode only, you kind of feel like you are brushing your teeth because the bristles inevitable makes contact. Maybe this is a good thing, I am not so sure.
You can use the sonic toothbrush and the water flosser at the same time rather than independently.
A clever concept that kills two birds with one stone as they say. I don’t dislike it, but it takes a bit of getting used to.
My testing was not to the standards of clinical trials, but you generally hold a toothbrush head at 45 degrees to the gumline, whilst with a water flosser this is at 90 degrees. Which approach do you take here?
I am sure overall it helps get a good clean. My teeth feel cleaner in this mode than brushing alone! The water being fired in at the same time gave the sensation that it was doing a better job.
This combined brush and floss mode would work well if you are in a bit of a rush and have limited time to clean the teeth.
It also works well for the self-confessed lazy flossers, who would simply skip the exercise otherwise. I have to give credit to Waterpik here.
Many people don’t brush for long enough, let alone clean interdental spaces, so if you can do both at the same time with some effectiveness, then wonderful.
But a point I want to raise is the sequence for brushing and flossing.
In Waterpiks demonstration videos, they suggest using the brush and then flossing.
However, assuming you brush with a fluoride based toothpaste, flossing with water afterwards will wash away much of, if not all of the protective layer left behind by the paste.
Therefore flossing first, then brushing is likely the better option.
Don’t get me wrong, brushing and flossing in any order is better than none at all, but surely it is best to get the maximum benefits from the toothpaste?!
What I wish to make clear here also, is that the Sonic-Fusion works for the average user, with no overly complicated dental history.
Those with periodontal pockets and those with implants will unlikely get the same level of satisfaction and cleaning effectiveness with this flossing toothbrush.
With most other Waterpik units, supplied or available as separate accessories, are different styles of tips, which are designed for different purposes.
For example, the plaque seeker tip is designed to help those with dental work such as crowns, bridges, and implants. The PikPocket tip is best for periodontal pockets and furcations.
It is always best to speak to your dentist so they can advise based on your personal circumstances, but if you have periodontal pockets, the level of effectiveness, might not be as good.
During the flossing, you can control the pressure to be one of 10 different settings.
The lowest is rated at just 10 PSI, with the highest at 100.
It is powerful and most will settle around 6, 7 or 8 in my opinion, a balance between comfort and flossing power.
The pressure setting used does dictate how much flossing time you get.
Waterpik claims 60+ seconds of flossing time, but I think they are selling themselves a little short here.
Set to pressure setting 10, from a full tank I achieved 1 minute and 25 seconds of flossing. That is 85 seconds in total.
When dropped down to the lowest setting, I achieved around 3 minutes and 30 seconds, that is 210 seconds in total.
Of course, you need to find what works for you, but you can more than likely get 2 flossing sessions from a full tank of water.
It is possible to use mouthwash in the flosser if you want or prefer. A dash in with the water often works well to give that extra freshness.
Giving extra credibility to the Sonic-Fusion is the fact that it is ADA accepted.
What does this mean?
Well, the American Dental Association (ADA) are one of the leading dental bodies within the USA and to earn their seal of acceptance, the product has to go through a series of tests and be scrutinized by many professionals.
Essentially, this is a great accreditation to have and it can give you extra confidence that this is approved by dentists and will help you improve your oral health.
Included in the box is a travel case, a useful accessory.
The case holds the brush handle and up to 2 brush heads, as is common.
It is hinged on the left side and opens up like a book.
Rather than being a solid color, the back half of the case is black plastic whilst the front is a transparent/clear plastic, so you can see the brush in the case.
There are vents built in so that air can flow and reduce moisture and bacteria built up.
The clip on the right side locks reassuringly into place protecting the brush in transit from damage and accidental activation.
The edges are curved and the overall size is fractionally taller than the brush handle itself and about twice as wide.
This case is for the brush only and not the water flosser element. Whilst you can move it, it is not travel friendly.
If going on vacation, the idea is you take the brush and leave the flosser at home.
And finally, Waterpik does offer a 36 month/3 year warranty as standard, should anything go wrong, which is excellent.
The unit is well built and looks good. Whilst it performs ok, this has not wowed me like I would have hoped. Some small usability and design elements are frustrating given the price.

Battery life does not normally apply to countertop water flossers as they usually only function when connected to mains power.
But, the Sonic-Fusion is a little different.
There is a battery in the toothbrush handle, which can be used without having to be connected to power.
To use the water flosser, you do need to plug the cord in, to power the pump.
A 2 pin US power cord is supplied. The unit does support 110-240v, so should you use it outside of America, you only need a plug adapter and not a voltage converter.
A Nickel Metal Hydride (NiMH) battery is built into the handle.
The battery is not user replaceable and needs to be recharged by sitting it on the base plate of the main uni.
From here the brush can be recharged wirelessly.
It takes approximately 4 hours to fully recharge the brush, which is quite quick in comparison to the leading brands.
You can leave the brush on the charging stand part of the base unit all the time it is not in use if you like. Whether you have it connected to power or not is up to you.
When sat on the charging stand and connected to power, the icons on the brush handle will be lit. Depending on the charge level of the battery will depend on how many lights are lit.
There are 3 lights in total that are lit by a white light.
The 3 LEDs essentially represent 33% of the battery charge each.
Each LED will flash to show it is charging. When that percentage is charged, the light will be a steady white.
If there are 3 fully charged lights then the brush is fully charged and after some time will go out completely.
When the brush is used, the lights will go out as the power drops.
If just 2 of the 3 lights are lit, you have somewhere between 33-66% charge in the battery.
When the battery is really low, the bottom LED will flash.
It would be good if it flashed red as this would likely catch the eye more and remind you it requires charging.
You cannot use the water flosser or the brush if the battery power is really low or depleted. There needs to be some charge in the brush handle even if you have the hose connected for flossing.
It is suggested that you should get 14 uses from a fully charged battery.
Based on two brushing sessions per day of 2 minutes in length that is 28 minutes of total usage time.
7 days of battery life is really below the standard I would expect of a new product like this. Most other electric toothbrushes now offer a minimum of 2 weeks (28 uses).
To be fair, most of the time it will remain sat on the charging stand when not in use, but if going on vacation, it would be nice not to have to worry about how you can and will charge it. For some, they would have to leave it at home if on vacation for a couple of weeks.
From my testing, I on average achieved 15 uses from a fully charged handle. The maximum was 19 brushing sessions, which totals 38 minutes or in other words 9 days between charges.
Summary of battery life
- Battery built into the brush handle
- The battery is not user replaceable
- Nickel Metal Hydride (NiMH) battery used
- Takes approximately 4 hours to charge the battery
- Last 7 days (14 uses)
- Poor in comparison to the competition
- LEDs give an indication of battery charge
- Red flashing LED would be useful when power is low
- Must be connected to mains power to use the water flosser
- 2 pin US power cord supplied
- Unit supports 110-240v
Price & where to buy
I have included links to buying options here at the start of the review.
In the section below, I discuss the price more generally and in relation to similar products.
As I mentioned within the variants section of this review, the two different models each have different recommended retail prices.
The SF-02 Professional model I have been hands-on with here as a suggested price of $199.99 whilst the SF-01 has a price of $169.99.
Unless buying directly from Waterpik, you can always save yourself a few dollars, generally around $20 off the retail price. There are a few dollars in it, depending on where you are looking. Some retailers do stay with the recommended prices, but most knock a bit off.
Therefore expect the prices to be around $150 and $170
I paid just $169.99 for this professional version, a saving of $30.
Waterpik themselves do quite often offer additional incentives, such as $30 off, but these are usually, mail-in rebate schemes and are not always offered.
As I write this review, several weeks after I bought it, I have found it being sold from a Waterpik approved seller for just $144. Add on the $30 rebate they are offering and this is not much over $100. This is a very good price, one that is unlikely to be offered all that frequently.
Of course, you do need to factor in the cost of replacement brush heads.
Supplied as a pack of 2, the price is around $25. That is $12.50 each, which is pretty pricey when you consider and Oral-B head is about $5.
These heads are priced at the premium end of the scale, but to be fair they are quite unique.
Here at Electric Teeth, we like to work out the cost of ownership over a 3 year period.
The SF-01 works out at approximately $288 or 26 cents per day, whilst the SF-02 Professional comes in at $305 or 28 cents per day.
Sharing the handle with another user or buying when the prices are particularly competitive will help keep ownership costs down. Perhaps you can wait until a rebate program is being run to save a few dollars extra.
Given the very small differences between the SF-01 and the SF-02, there isn’t an absolute need to get this professional model. You are going to have to make a call based on the prices and your desires.
Sadly though, I don’t think these products are worth the prices being asked of them.
I have mentioned how a separate electric toothbrush and water flosser might well be a better option.
Using the Sonicare ProtectiveClean 4100 and the Waterpik Aquarius as examples, I can purchase these for $40 and $60 respectively.
At around $100 that is quite a saving and arguably offers just as much if not more.
Waterpiks complete care 9.0 or 9.5 is anywhere between $100-120. That is a saving of at least $30 or as much as $100 for a very similar system, which offers the benefit of separate flosser and toothbrush.
Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase. These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Reliability & long term use
Having tested the Sonic-Fusion for only a few weeks, I cannot speak completely honestly about the reliability and long term use of this product.
I have used many Waterpik products over the years and have been impressed with the quality and construction and the newest products are made to an even better standard, the Fusion included.
Being a new style of product, it does open itself up to possible weaknesses not seen or experienced with conventional water flossers.
Having taken a close look at the unit, I see no obvious weaknesses. Materials feel good, the general fit and finish is to a high standard and items like the hose clip into the handle well.
Only time will really tell, but I will have to rely on readers and other users who commit to this for the long term to report any issues.
Should the worst happen, it is nice to see that Waterpik offer a 3 year/36 month warranty.
Very few brands offer a guarantee for this length of time. For me this is a sign of Waterpiks confidence in their own product, but also the level of commitment they wish to deliver to users.
Do consider though, if this breaks you have lost your water flosser and toothbrush whilst it is repaired or replaced. At least with separates, you are not left with nothing.
Conceptually, I like the idea of the Sonic-Fusion.
In reality, I am a bit disappointed.
It has failed to wow me.
The toothbrush is satisfactory. It cleans the teeth, but it makes an irritating noise. The battery life is poor.
The water flossing works, but the brush head rather than nozzle design limits the suitability for certain users.
Waterpik have a solid reputation for water flossers and sadly, I don’t think this shows off the best of Waterpik, combining of the two hasn’t really paid off.
It is innovative, and for some, the convenience of the dual purpose device like this will be a game changer, but for what it is worth, my opinion is to stick to separate items.
You could opt for one of Waterpik’s complete care systems or a good electric toothbrush, such as the ProtectiveClean 4100 from Sonicare and then have a water flosser such as the Aquarius WP-660 from Waterpik.

All are approximates
- Does it come with a charger?
- Yes, a 2 pin US power adapter. The power supply supports 120-240V.
- How often do the brush heads need replacing?
- Brush heads should be replaced every 3 months.
- Can I use mouthwash in the Waterpik?
- You could, but it could be expensive and wasteful. Best adding a dash into the water used in the reservoir for a burst of freshness.
- How much water or mouthwash does it hold?
- 15 ounces (440ml) with the SF-01
- 14 ounces (420ml) with the SF-02
- My gums bleed when brushing and flossing. Is that normal?
- Bleeding gums may be a sign of infection and a little bleeding can be normal when starting a new oral care routine, as you may be cleaning in areas not previously reached. However, if bleeding is excessive or does not stop within a few days of regular use, consult a dental professional.
