Water flossing is the arguably more enjoyable alternative to regular dental flossing, but it’s something that takes a bit of getting used to, you need the right technique.
There are also lots of different options when it comes to water flossers and not all are created equal.
So, if I was to tell you that this water flosser is the winner of our ‘best water flosser’ then you will be interested to know more, right?
Read our Waterpik WP-660 review below to find out what makes this model so special.

What is the Waterpik Ultra Professional Water Flosser?
This is a countertop water flosser.
It has to be connected to mains power to be used and cannot be used wirelessly.
Taking water from a refillable on board tank, the pump inside the flosser takes that water and feeds it out through a nozzle on the handle of the flosser.
The water jet that exits the flosser can be altered in its pressure, the angle at which it is directed and more.
An alternative to string floss, the water passes in between teeth and gums as well as under the gumline to remove plaque, bacteria and food particles that make up the 35% of teeth surfaces that do not get cleaned with regular brushing.
Manufactured by the market leading brand, clinical trials have resulted in significant improvements in oral health, including a 93% improvement in reducing bleeding and up to 52% better at reducing gingivitis than traditional dental floss.
Variants of Waterpik Ultra Professional Water Flosser
There are 2 versions of this flosser. The difference is the colour of the unit, one is White and one is Black.
The WP-660 is the White colour option whilst the WP-662 is the Black coloured unit.
It is the WP-662 that I am testing in this review.
The White is the more popular colour option.
You may see the model number with the letters UK after them, I.E WP-660UK.
This is to identify that this is a version made for the UK that comes with the appropriate 2 pin plug and power adapter suitable for connecting to sockets found in many bathrooms in the UK.
Aside from the colour there are no other differences between these units.
I will refer throughout to both these models.
How to use the Waterpik WP-660UK Water Flosser
There is certainly a technique to using a water flosser.
The mains steps are as follows
- Step 1: Fill the water tank/reservoir with lukewarm water (tank can be lifted out and replaced).
- Step 2: Fit the appropriate nozzle to the handle of the flosser ensuring it has clipped into place.
- Step 3: Adjust the pressure dial on the unit to your desired pressure level (can be adjusted later). If it’s your first time using, turn down to a lower setting.
- Step 4: Press the power button to switch the unit on.
- Step 5: Lean over the sink and place the tip of the flosser into your mouth. Close the lips enough to prevent splashing while still allowing water to flow from mouth into the sink.
- Step 6: Slide the switch on the handle from off to on, the water will begin to flow.
- Step 7: Aim water at the gumline at a 90 degree angle. Follow the gumline and pause briefly between teeth.
- Step 8: When complete, slide the button to ‘off’ and then press the power button to turn it off.
During the clean you can adjust the pressure, turn the nozzle and control water flow by sliding the switch to the on or off position during the clean.
Why not see how it is done on video:
And now for a bit more detail….
There will always be arguments for and against flossing be that with string or water.
Evidence will favour both sides and there will always be the dramatic headlines that say you need to or don’t bother flossing.
Make your own judgement cal,l but general advice is that it is better to floss, if precautionary more than anything. Those who do floss typically suffer less with gum disease and similar gum related issues.
Sting floss is cheap, but it is awkward. Interdental brushes are a great alternative (you can learn more in our post interdental brushes all you need to know but it still takes time
Water flossing on the other hand typically takes a lot less time once the technique has been mastered and it can be as effective.
Although water to floss is something that has actually been around for a long time it is not all that heavily promoted, but they are slowly becoming more common.
US firm Waterpik are the market leaders and regularly allow for their products to be tested and critiqued and have generally won the backing of many dental professionals worldwide.

Pros & Cons
Here are the quick fire pros and cons of this water flosser.
- Clean – It feels like it has cleaned well without the harshness of traditional floss with clinically backed results.
- Pressure settings – Adjust it to what you like with 10 different settings there is a lot of control.
- Box contents – Good box contents with multiple tips.
- Size & Design – Despite being bigger than most would ideally want it has been fairly well designed to keep a small profile and the Black colour option is a nice touch. Decent sized water tank too.
- Mains power – It requires mains power to work. If you do not have a shaver socket in your bathroom this might be an issue.
- Size -Its a little bulky, not ideal for the smallest bathrooms with limited work surface space.
- Messy – Not a product con as such but more as a result of how water flossers work, it can take some time to get used to the right technique and avoid making a mess.
- Colour/Accessories – The availability of the Black colour matched accessories is not great.
Design, Usability, Clean & General Use
This is not the most exciting product you will ever unbox, the packaging is fairly standard for this type of product.
The outer box has lots of strong marketing messages and product features highlighted. While this can be overbearing at times, at least it is well laid out and easy to distinguish.
Some packaging is so basic you really can’t get much info about a product before you buy it.
Testing out the WP-662UK here for this review, the box was colour matched which is nice to see.
Once unboxed you will notice the unit is not small but actually nicely sized and well designed given that there is a 600ml tank built into it.
On the top is a lid which lifts up and locks into place to allow the clear water tank (complete with ml and Oz markings) be lifted out and filled.
The tank has a valve which seals closed until it is firmly pressed back into the unit at which point the seal opens to allows water to flow into the pipework ready for pumping out of the nozzle.
7 different tips come supplied with the WP-662UK as you will see in the box contents listing.
The same tips come supplied with the WP-660UK, the only difference is the colour of the units.
The nozzles that are provided are:
- 3 x JT-100E – Waterpik Classic Water Flosser Tips (view on Amazon)
- 1 x OD-100E – Waterpik Orthodontic Tips (view on Amazon)
- 1 x PS-100E – Waterpik Plaque Seeker Tips (view on Amazon)
- 1 x PP-100E – Waterpik Pik Pocket Tips (view on Amazon)
- 1 x TB-100E – Waterpik Water Flosser Toothbrush Tips (view on Amazon)
There only other nozzle that is not supplied is the:
- TC-100E – Waterpik Water Flosser Tongue Cleaner (view on Amazon)
Worth noting is that most of the tips came colour matched to the Black WP-662, but purchasing these as separate accessories is difficult. Availability may improve, but at the time of writing there were not really Black coloured tips available, everything was designed for the more standard White coloured unit.
Each tip works best in different scenarios.
The classic tip and toothbrush is best for most everyday use.
If you have braces, the orthodontic tip is ideal.
Pik pocket tip is suited to those with periodontal pockets and furcations.
Those with implants, crowns, retainers and bridges will likely see best results from the plaque seeker tip.
The left hand side of the unit has a plastic panel that leads up to the hinging for the lid. When opened and the tank removed, just inside are 2 holes into which your most used tips can be stored.
This is a neat solution, but does not give a home to all 7 tips. A 3rd could remain fitted to the handle.
Waterpiks other model, the Ultra, is better equipped to store multiple heads.
For most, users there will be favoured heads and not all will need and want all so you will have to make your decision as to what is most suitable for you.
Under the water tank is the main body of the unit that houses the pump and electrics. This is encased in the smooth to touch plastic.
There are 5 rubber feet on the flosser slightly raised off the worktop.
Sitting at the front of the unit (slightly off centre to the right) is the main nozzle/handle.
Docked into a little holder the length of hose coils into a recess within the body of the flosser. You have about 100cm of length from the tip of the nozzle to the hose running into the flosser. That is enough length for most.
The hose is colour matched too and the handle is accented with nice silver/grey switches.
On the side is a sliding switch to release the nozzle which on the front is a much larger and clearly market On/Off slider. This controls the water flow.
The handle is rounded and tapered and fits nicely in the hand. Although smooth there is a contour to the plastic that helps with grip and there are 3 ridges on the power button.
At the top of the handle is where the detachable nozzle fits and the upper section of the handle can be rotated a full 360 degrees to position the nozzle tip precisely.
To the left are more controls. A raised power button actually turns the unit on and off.
A concave button below switches between ‘Floss’ and ‘Massage’ mode.
Below this is a largish knob that can be rotated to match up with the 10 pressure settings available.
The rear of the unit has the power outlet cable that stretches to about 140cm.
A 2 pin connector is found on the end to connect to the sockets found in most UK bathrooms.
If you do not have a socket in the bathroom (like me) you can buy adapters to connect it to a 3 pin UK mains supply but be aware of the complications with trailing cables and positioning and using a unit safely.
When it comes to actually using the steps you need to take are outlined earlier in this review.
However there are some things to note and be aware of that help you and improve your use.
It is not essential, but recommended to use lukewarm water. This is because it is more pleasant on your gums when flossing.
You can use mouthwash but it would be expensive and wasteful and if you want an extra shot of freshness or flavour to the flossing add a capful or two to the water tank.
The tank is 600ml in capacity and will last roughly 90 seconds in daily use. Subject to how you use it you might just stretch 2 flossing sessions out of it.
For the best results you should start with the back teeth and work forward. Direct the jet at a 90 degree angle, working along the gumline with a brief pause between teeth. The rotatable tip will aid with this. As you get more proficient you will be able to twist the nozzle without having to stop the water flow.
When in use the unit will pause very briefly at 30 seconds to remind you to move onto the other arch of your mouth. If you have an electric toothbrush with a built in timer it is a similar principle.
At 60 seconds it will pause again to let you know you have reached the recommended usage time.
It need take no longer than a minute to floss your mouth. You do not need to spend 2 minutes like you do with a toothbrush.
You should not use the flosser for more than 5 minutes in any 2 hour period and it will automatically shut off if used for 5 continuous minutes as a safety precaution.
Selecting the ‘Floss’ mode and changing the pressure setting is most common, but this model does too have a Hydro-Pulse Massage.
Essentially a unique pattern of water exits from the nozzle and can be used on the gums to stimulate them. This is ideal for those with sensitive gums and suffering from periodontal disease.
Now make no mistakes if you are new to this, it is more messy than regular flossing and it will take some getting used to. Don’t be surprised by a lot of dribbling and maybe a big of spray (it’s only water). But soon it will be easier and more enjoyable.
You can’t pop this in your bag or pocket for a quick freshen up on the go, but the water reaches deep into the mouth and really does remove bacteria and food stuffs you didn’t even realise were there.
You won’t be struggling to get to your back teeth like you do with regular floss due to the long nozzle and easy reach.
The power setting choice will be personal, most I believe will hover from about 5-7, that feels like a nice comfortable mid ground.
How often you use this is up to use. Once a day is the minimum you should use it really.
It can be used perhaps after a meal to quickly freshen up as an alternative to brushing the teeth.
Many of us suffer with red, swollen or bleeding gums and that is believe it or not as a result of not flossing or brushing correctly. It is the bacteria buildup that causes the gums to react.
Regular use will lead to healthier gums as the bacteria is removed and the gums begin to recover. So confident are Waterpik that they offer a 14 day money back guarantee as well as a 3 year warranty.
If you purchase a Waterpik Water Flosser and don’t feel it’s improved your gum health, they will refund your money – no questions asked. What have you got to lose?
I think this is as close to perfect as you can get for a water flosser…unless there is one that can help master the technique better.
Summary of Design, Usability, Clean & General Use

- 600ml water tank
- Storage space for 2-3 nozzles
- 7 nozzles provided in the box
- 1m length on hose

There is a physical cost to this flosser and that recommended retail price is £79.99.
The good news is that without much shopping around you can save about £10-15, with the average selling price being around the £65.
Shop smart and you may save another £5, but often the sale price is not too far from the retail price, because the RRP is not over inflated like it is with some other dental products.
Assuming one user, using this over a 3 year period, the cost of ownership would work out at approximately £75.50 which is 7p per day.
This does include the cost of replacement nozzles which are somewhere around £3.50 per nozzle and require replacing every 3 months (jet tips can be replaced every 6).
No denying that good old string floss is as much as 7 times cheaper, but what price do you pay for convenience.
I reckon each flossing session you save yourself about a minute (not a scientific study).
Not only is there the time saved, there is the ease with which water flossing is completed in comparison.
What price can you put on the convenience that comes as a result?
Yes cheaper options exist, but they do not have all the same features, you are getting a very good option for less than 10p per day and the benefit will be your oral health.
Get more members of your family using it and there are only further savings to be made by sharing the cost between more users.
Please note that all costs quoted are approximates and prices will vary based on location, supplier, time of purchase. These figures should not be relied on as hard fact but as a guide, based on real information at the time of writing.
Summary of Price
- Recommended retail price of £79.99
- Average selling price £65, can be under £60
- Replacement nozzles retail for £3.50 each
- Daily cost around £0.07 over 3 years
- Expensive but arguable benefits
Reliability & Long Term Use
To suggest that this would never go wrong I cannot.
However there are few complaints of Waterpik products being inherently faulty.
Compared to the Freedom Cordless flosser I have used from Waterpik this looks and feels more premium.
In the few weeks I have tested all has worked fine and I see little in the way of obvious weaknesses. Buttons are fairly resistive, the pressure control knob is not loose and other fitments solid.
There are not lots of parts to go wrong, but electrical products can fail, particularly when near water like this is. However it is backed by an impressive 3 year warranty. When many offer just 1 year this is going above and beyond.
I suspect you will get good value from this unit.
It is arguably a slightly expensive luxury, when flossing the old fashioned way is cheaper.
However, there is a lot to be said for the convenience and the way in which you will be more encouraged to use this and I believe floss more regularly than you would otherwise.
It is not small, it does require mains power but it has been well designed and comes with a good selection of tips that makes this work particularly well in a family environment.
The adjustable pressure caters to different users needs and timers help prevent over flossing but also encourage better routines.
Convenience and the comfort in flossing with the Waterpik are the biggest draws.
The 3 year warranty is a bonus and offers a nice extra peace of mind to this investment.
This is the best corded water flosser available today in my opinion.
